maths geometry
Step-by-step explanation:
since both shapes are totally symmetric, a few answers are obvious :
(1) F2 = F1 = 50°
(3) B1 = D1 = 20°
last but not least, D2 = B2.
using the fact that the sum of all angles in a triangle is always 180°.
and that the sum of all angles sind a single point on one side of a line is also always 180° :
in the triangle CDF the inner angle C is
C = 180 - 20 - 50 = 110°.
therefore, C1 = 180 - 110 = 70°
E1 = 90° (a major rule for the diagonals of a kite).
D2 = 180 - 90 - 70 = 20°
and so, B2 = 20°
(2) D2 = 20°
(4) B2 = D2 = 20°

The largest interval in which the function is continuous is given by:
(-∞, -3).
What is the continuity concept?A function f(x) is continuous at x = a if it is defined at x = a, and:
[tex]\lim_{x \rightarrow a^-} f(x) = \lim_{x \rightarrow a^+} f(x) = f(a)[/tex]
A function is also not continuous for the values of x which are outside the domain of the function, hence a fraction is not continuous at the zeroes of the denominator.
In this problem, the zeroes of the denominator of the function are:
x = -3, x = 4.
Hence the continuity intervals are:
(-∞, -3).(3,4).(4,∞).The largest one is the first, as |-3| < |4|, meaning that it is a larger distance from infinity.

A group of exchange students from Japan went to a convalescent home to sing songs for the seniors and to demonstrate origami. Groups of students and seniors sat together at tables so the students could teach the seniors to fold some origami figures. As it turned out, at each table there was either 1 student and 3 seniors, or 2 students and 4 seniors. There were 23 students and 61 seniors in all. How many tables were being used?
Answer:
19 tables
Step-by-step explanation:
Let X represent the number of tables that have 1 student and 3 seniors
Let Y represent the number of tables that have 2 student2 and 4 seniors
Therefore number students total
1X + 2Y =23 (1)
Number of seniors total
3X + 4Y = 61 (2)
Multiply equation (1) by 2 giving
2X + 4Y = 46 (3)
Subtract (3) from (2)
3X + 4Y - (2X+4y) = 61-46
3X + 4Y - 2X -4Y = 15
3X-2X = 15
X = 15
Plugging this value into equation (1) gives
1(15) + 2Y = 23
15 + 2Y = 23
Subtract 15 from both sides
2Y = 23 - 15
2Y = 8
Divide by 2 both sides
Y = 4
Thus total number of tables used = X +Y = 15+4 = 19

A student on the track team runs 45 minutes each day as a part of her training. She begins her workout by running at a constant rate of 8 miles per hour for 푎 minutes, then slows to a constant rate of 7.5 miles per hour for 푏 minutes. Which equation describes the relationship between the distance she runs in miles, 퐷, and her running speed, in miles per hour?
D = RT would be the fundamental equation to answer this, which is
Distance in D
Rate is R (speed)
It is now.
We can determine the individual distances for the two legs of the whole to determine the overall distance D.
Initial Leg:
R = 8
T = a
D = 8a
8(45 – b) + 7.5b =D
What is the formula for rate and distance?
Use the formula d = st to determine speed, distance, or time. Distance is equal to speed multiplied by time. Given two known numbers, the Speed Distance Time Calculator can solve for the unknown sdt value.
Units of seconds (s), minutes (min), hours (hr), or hours, minutes, and seconds can be used to input or solve for time (hh:mm:ss). Time format shortcuts are shown below.
Use the formula d = st, or distance equals speed times time, to find the distance.
Distance Equals speed x time
Since both reflect a certain amount of distance per unit of time, such as miles per hour or kilometers per hour, rate and speed are comparable. If speed s and rate r are equal, then r = s = d/t. The corresponding formula is d = rt, which denotes Rate times time are equivalent to distance.
Distance = Rate x Time
Use the speed formula, s = d/t, which states that speed is equal to distance divided by time, to solve for speed or rate.
speed equals distance/time.
Use the time formula, t = d/s, which states that time is equal to distance divided by speed, to solve for time.
Time = Speed/Distance

When a constant force acts upon an object, the acceleration of the object varies Inversely with its mass. When a certain constant force acts upon an object with
mass 7 kg, the acceleration of the object is 10 m/s². If the same force acts upon another object whose mass is 5 kg, what is this object's acceleration?
The acceleration of the object is found as 14 m/s².
What is defined as the Newton's second law of motion?Newton's second law states that acceleration of an object is determined by two variables: the net force acting on it and its mass.
The acceleration of the body is proportional to the net force exerting on it and inversely proportional to its mass. This implies that as the force that acts on an object increases, so does the object's acceleration. Similarly, as an object's mass increases, the object's acceleration decreases.The formula for the Newton's second law is;
F = ma
F = acting force in Newton
m = mass of the body in Kg.
a is the acceleration in m/s².
The mass of 7 kg accelerates with 10m/s².
Force acting on it is;
F = ma
F = 7×10
F = 10 N.
The same force is acting on the body of mass 5 kg.
F = ma
a = F/m
a = 70/5
a = 14 m/s².
Therefore, the acceleration of the body is found as 14 m/s².

How many apples does Maria have?
The number of apples Maria has after giving 1 apple to Lillian at the end is is 5 apples.
Given data:
The expressions representing the change in values of the apples are:
Lilian starts with 12 apples, and she gives half (6 apples) to Sebastian. She now has 12 - 6 = 6 apples.
Sebastian starts with 6 apples and gives 2 apples to Jose. He now has 6 - 2 = 4 apples.
On simplifying the expressions:
Maria starts with 6 apples and gives 2 apples to Jose. She now has 6 - 2 = 4 apples.
Sebastian gives half of his remaining apples (4 / 2 = 2 apples) to Maria. Maria now has 4 + 2 = 6 apples.
Maria gives 1 apple to Lilian. She now has 6 - 1 = 5 apples.
Hence, at the end of the given actions, Maria has 5 apples.

The coordinates of point E is (-37/7, 23/7)
Calculating the midpoint of a line using a ratioThe formula for calculating a coordinate points using the points (-1, -1) and point A is located at (-7, 5) in the ratio 2:5 is expressed as:
E (x, y) = {(ax₁+bx₂)/a+b, (ay₁+by₂)/a+b}
Substitute the coordinates and ratios to have;
E (x, y) = {(2(-1)+5(-7))/2+5, (2(-1)+5(5))/2+5}
E(x, y) = {-35-2/7, -2+25/7}

Jim began a 145mile bicycle trip to build up stamina for a triathlon competition. Unfortunately, his bicycle chain broke, so he finished the trip walking. The whole trip took 7 hours. If Jim walks at a rate of 4 miles per hour and rides at 30 miles per hour, find the amount of time he spent on the bicycle.
The amount of time he spent on bicycle is 4.5 hours.
Given Jim began a 145 mile bicycle trip.
The whole trip took 7 hours.
Jim walks at a rate of 4 miles per hour and rides at 30 miles per hour.
speed = distance / time
time = distance / speed
ride:
d = distance ridden
t = d/30 (given from the problem)
walk:
t = (145 - d)/4 (given from problem)
total trip time:
7 = d/30 + (145 - d)/4.
7 = 4d/120 + 30(145 - d)/120
7×120 = 4d + 30(145 - d)
840= 4d +4350-30d
840 ₋ 4350 = ₋30d ₊ 4d
₋3510 = ₋26d
d = 3510/26
d = 135
d=135 then from here using the formula t = d / s we can solve
t=135/30 = 4.5 hours
hence the amount of time Jim spent on the bicycle is 4.5 hours.

Ashley is the oldest of four siblings whose ages are consecutive even integers. If the sum of their ages is 100, find Ashley's age.
Answer:
Ashleys age is 28.
Step-by-step explanation:
When finding numbers that are consecutive, I like to divide the sum in this case, 100 by the number of people or things, in this case, the 4 siblings. The sum is 100 and there are 4 of them so we divide them first.
100÷4=25 so our answer must be around there. The question states that the ages must be even. So the even numbers in the range of lets say 20-30 are 20, 22, 24, 26, 28 and 30. Closest four numbers to 25 are 22, 24, 26 and 28. We must have two numbers below 25 and two numbers above 25. So we will keep 22,24,26 and 28. If you add them together, then you'll get 100! Since we are looking for Ashley's age which is the oldest, her age will be 28 as 28 is the highest number out the four numbers (22,24,26,28)

What is a histogram?
A histogram is a graph that shows the frequency of numerical data using blocks. The height of a cube( the perpendicular axis) represents the distribution frequency of a variable( the quantum, or how frequently that variable appears). A histogram is a graphical display of data using bars of different heights. In a histogram, each bar groups figures into ranges. high bars show that further data falls in that range. A histogram displays the shape and spread of nonstop sample data. Histograms fantasize quantitative data or numerical data, whereas bar maps display categorical variables.From the frequency table, we get the frequency of the first class is 20(twenty), and for the second(2) class it is 10(ten) also the remaining frequencies are correctly shown by the histogram shown in option C.
Hence, C is the correct(right) answer.
