Answer:
From top to the bottom:
Acute,
Right,
Straight
Step-by-step explanation:
An acute angle is formed when the measure of the angle is smaller than 90° which is provided in te first image.
A right angle is formed when the measure of an angle is precisely 90° which we can see in the second image.
A straight angle is formed when the measure of an angle is precisely 180° no less no more, which we can see in the last image.
Solve (8×5)÷4×5 step by step
Answer:
50
Step-by-step explanation:
Apply PEMDAS to this problem
8 × 5 = 40
Now you are left with: 40÷4×5
You then use PEMDAS from left to right from here
So 40 ÷ 4 would be 10, and now you are left with 10 × 5, which would be 50.
From midnight to 7:00 am, the temperature rose 1.1 C each hour. If the temperature at 7:00 am was -0.3 C, what was the temperature at midnight?
The temperature at midnight is -8°C.
How to calculate the temperature?Let the initial temperature be x.
It should be noted that there are 7 hours between midnight and 7am.
Therefore, the equation will be:
x + (1.1 × 7) = -0.3
x + 7.7 = - 0.3
x = -0.3 - 7.7
x = -8
The temperature at midnight is -8°C.

Find x and y pleaseee
Answer:
x = 23 y = 42
Step-by-step explanation:
y + 54 + 4x - 8 = 180
y + 4x = 180 - 46
y + 4x = 134
180 - (5x - 19) = 4x - 8
180 - 5x + 19 = 4x - 8
180 + 19 + 8 = 4x + 5x
207 = 9x
207/9 = x
x = 23
y + 4(23) = 134
y = 134 - 92
y = 42

The value of the expression (12 - 3/5√25)^2 + (2 - 4)^2 is 85
How to evaluate the expression?The expression is given as
(12 - 3/5√25)^2 + (2 - 4)^2
Evaluate the square root of 25
So, we have
(12 - 3/5√25)^2 + (2 - 4)^2 = (12 - 3/5 * 5)^2 + (2 - 4)^2
Evaluate the product
So, we have
(12 - 3/5√25)^2 + (2 - 4)^2 = (12 - 3)^2 + (2 - 4)^2
Evaluate the difference
So, we have
(12 - 3/5√25)^2 + (2 - 4)^2 = 9^2 + (2 - 4)^2
Evaluate the exponent and the sum
So, we have
(12 - 3/5√25)^2 + (2 - 4)^2 = 85
Hence, the value of the expression (12 - 3/5√25)^2 + (2 - 4)^2 is 85

A water tank is a cuboid 45cm long, 30cm wide and 26cm high. it contains water to a depth of 21cm. a sphere is placed in the tank and is fully submerged. the water level rises by 1.8cm. volume of a sphere is 4/3 pi r^3 . calculate the radius of the sphere (nearest mm)
The radius of the Sphere that submerged in the water is 178.9 mm.
Volume of the Cuboid:
Volume of cuboid is the total space occupied by the cuboid in a three-dimensional space.
The general form of the Volume of the Cuboid is,
Volume of a cuboid = l × b × h [cubic units]
Where,
l = length
b = breadth
h = height
Given,
A water tank is a cuboid 45cm long, 30cm wide and 26cm high.
It contains water to a depth of 21cm.
A sphere is placed in the tank and is fully submerged. the water level rises by 1.8cm.
Here we need to find the radius of the Sphere and we have to use the Volume of the sphere as 4/3πr³.
First, we need to find the volume of the water,
For that, we have to take the measurement of it.
l = 45 cm
b = 30 cm
h = 21 cm
( here we have to find the volume of water, so we have take the water depth as its height)
Now, the volume of the water is,
V₁ = 45 x 30 x 21
V₁ = 28350 cm³
After placed the sphere on the tank the water level is increased as 1.8 cm,
So, the new height = 21 + 1.8 = 22.8
Now the new volume is,
V₂ = 45 x 30 x 22.8
V₂ = 30780 cm³
So, the Volume of the increased water level is,
=> 30780 - 28350
=> 2430 cm³
Now we have to consider this as the Volume of the Sphere and calculate the radius through it,
=> 4/3πr³ = 2430
=> r³ = 2430 x 3/4 x π
we know that the value of π = 22/7
So,
=> r³ = 2430 x 3/4 x 22/7
=> r³ = 5727.86
=> r = ∛5727.86
=> r = 17.89
Therefore, the radius of the sphere is 17.89 cm
Now we have to convert it into mm,
=> 1 cm = 10 mm
So,
=> 17.89 cm = 178.9 mm
Therefore, the radius of the sphere is 178.9 mm.

pls help me
Answer: 144N
Step-by-step explanation:
A=acceleration. N=net force. M=mass
A=N/M

If the price of an apple is $0.50, the marginal utility per dollar spent on the fifth apple is: ________
a) 20
b) 30
c) 40
The marginal utility per dollar spent on the fifth apple is 60. The correct option is D.
What is marginal utility?The marginal utility simply refers to the change or extra satisfaction derived from the change in consumption.
Hence, the marginal utility of the fifth apple equals :
Difference /change or extra satisfaction derived by consuming one more than 4 apples = (total utility of 5th apple - total utility of 4th apple)
= (250 - 220) = 30
Hence, marginal utility per dollar: Marginal utility/price per apple
Price per apple = $0.5
Marginal utility of 5th apple = 30
Marginal utility of 5th apple = 30 / 0.5
Marginal utility of 5th apple = 60
Therefore, the marginal utility per dollar spent on the fifth apple is 60. The correct option is D.

find the derivative of f(x)=3x+5
Answer: Derivative of f(x) =3x+5=3
Step-by-step explanation:
By the Sum Rule, the derivative of 3x+5 with respect to x is d/dx[3x]+d/dx[5]
d/dx[3x]+d/dx[5]
evaluate: d/dx[3x]
Since 3 is constant with respect to x, the derivative of 3x with respect to x is 3d/dx[x].
3d/dx[x]+d/dx[5]
Differentiate using the power rule
which states that d/dx[[tex]x^{n}[/tex]] is [tex]nx^{n-1}[/tex] where n=1.
3⋅1+d/dx[5]
Multiply 3 by 1.
3+d/dx[5]

The linear combination of u and v = <3,-27>=5U+4V.
What does linear combination in vectors mean?A linear combination of two or more vectors is the vector formed by multiplying two or more vectors (with distinct directions) by scalar values. The above equation demonstrates that the vector is produced by adding two vectors to three vectors.
What is the term "linear combination"?The term "linear" has two independent meanings: geometric and algebraic. Because linear combinations essentially linear in the both senses, the expression is accurate.
According to the given information:Let u= <3,3> and v= <-3,3>
<3,-27> = x< 3,3> + y<-3,3> = <3x - 3y, 3x + 3y>
3x - 3y = 3 => x - y = 1
3x + 3y = -27 => x + y = -9
Adding both, we get

Trigonometric Identities are equality statements that hold true for all values of the variables in the equation and that use trigonometry functions.
There are numerous distinctive trigonometric identities that relate a triangle's side length and angle. Only the right-angle triangle is consistent with the trigonometric identities.
The six trigonometric ratios serve as the foundation for all trigonometric identities. Sine, cosine, tangent, cosecant, secant, and cotangent are some of their names. The adjacent side, opposite side, and hypotenuse side of the right triangle are used to define each of these trigonometric ratios. The six trigonometric ratios are the source of all fundamental trigonometric identities.

34.3 Km /h was her average velocity in km/h.
What is average velocity?
The change in position or displacement (x) divided by the time intervals (t) during which the displacement happens is the definition of average velocity. Based on the direction of the displacement, the average velocity might either be positive or negative. Meters per second (m/s or ms-1) is the SI measure for average velocity.The displacement of a body, or the shortest distance it must go during a trip, is calculated as the displacement multiplied by the time interval over which it covered that distance.average velocity = Displacement / time taken
V = d/ l

The standard deviation is 2.24 if the sum of squares for a sample containing 101 items equals 500 option (C) is correct.
What is the standard deviation?It is defined as the measure of data disbursement, It gives an idea about how much is the data spread out.
[tex]\rm SD = \sqrt{\dfrac{ \sum (x_i-X)^2}{n-1}[/tex]
SD is the standard deviation
xi is each value from the data set
X is the mean of the data set
n is the number of observations in the data set.
∑(x(i) - X)² = 500
n = 101
SD = √(500/101-1)
SD = √5
SD = 2.236 ≈ 2.24
