Answer:

1/5 mile

Step-by-step explanation:

1/10 mile in 1/2 second

This can be written as a ratio:

1/10 mile : 1/2 second

We need the ratio in terms of 1 second, so multiply both numbers in the ratio be 2.

2 × 1/10 mile : 2 × 1/2 second =

= 2/10 mile : 1 second

= 1/5 mile : 1 second

Answer: 1/5 mile

The change as a percentage is 6.7 %

The price of the building in the year 2021 is $4,200,00

The price of the building in 2021 is $4,500,000

Therefore the percentage change can be calculated as follows

= 4,500,000 - 4,200,000/4,500,000 × 100

= 300,000/4,500,000 × 100

= 0.066 × 100

= 6.7 %

Hence the percentage change is 6.7%

The value of a in the equation in the simplest form will be 17 / 6.

We are given an equation:

x³ / x^(1/6) = x^(a)

We need to evaluate the left hand side to find the value of a in the equation in simplest form.

We know that:

x^ (a) / x^ (b) = x^ ( a - b)

Using this, we get that:

x^ (3 - 1/6) = x^ (a)

x^ (17/6) = x^ (a)

By comparing the bases, we get the value of a as:

a = 17 / 6.

Therefore, the value of a in the equation in the simplest form will be 17 / 6.

Answer:

y=-3

Step-by-step explanation:

First, we start with the basic line equation:
y=ax+b
Plugging in the two points, we get
-3=a(5)+b and
-3=a(-3)+b
Simplifying we get
b=-3-5a
b=-3+3a
Setting the two equations equal, we get
-3-5a = -3+3a
8a = 0

so a =0
plugging in a into the first equation
-3=0(5)+b
b=-3

and finally plugging a and b into y=ax+b we get

y=-3

If this was helpful pls give me brainliest <3

Equation: [tex]y=-3[/tex].

To find the slope of this equation, let's refer to the formula of slope:

Slope (m)= [tex]\frac{y_{2}- y_{1} }{x_{2}- x_{1} }[/tex]

Identify the points:

Let the ordered pair of (5, -3) take the number 1 for the notation. Hence:

[tex]x_{1} =5\\\\y_{1} =-3[/tex]

Note. This assigment of number 1 can be done arbitrarily, we could've named the coordinates of the other ordered pair as number 1 and the result would be the same.

Now, identify the values of the remaining ordered pair.

[tex]x_{2} =-3\\\\y_{2} =-3[/tex]

Substitute the values into the slope formula and calculate.

[tex]m=\frac{(-3)-(-3)}{(5)-(-3)} \\ \\m=\frac{-3+3}{5+3}\\ \\m=\frac{0}{8} \\ \\m=0[/tex]

To find the equation, we're going to use the formula for crafting linear equations which is the following:

[tex]y-y_{1} =m(x-x_{1} )[/tex]

Substitute the values into the formula and calculate.

[tex]y-(-3) =(0)(x-(-3) )\\ \\y+3=0\\ \\y=-3[/tex]

Note. For this formula you may use any of the ordered pairs to substitute.

Answer:

With a circle with radius 7 cm, the circumference of given circle is 14π (cm) and the area is 49π (cm²).

Step-by-step explanation:

Given: radius = 7 cm

Circumference of a circle: C = 2πr

C = 2πr

Substitute given value radius.

C = 2π(7)

Multiply 7 and 2.

C = 14π cm.

Area of a circle: A = πr²

A = πr²

Substitute given value radius.

A = π(7)²

Square the 7.

A = 49π cm²

Points A, B, C, D, and E are collinear and in that order. The value of Ac is 18.

According to the segment addition postulate, if two points on a line segment, A and C, are given, a third point, B, will only be found on line segment AC if and only if the distances between the points satisfy the conditions of the equation AB + BC = AC.

Keep in mind that a line segment is a portion of a line that has two distinct end points. There are many points between the two end points that make up the object.

The segment addition postulate can be stated more simply by saying that if point B lies on line segment AC, then AB + BC will equal AC.

by the segment addition postulate,

AC + CE = AE so AC = AE - CE

AC = (x+50) - (x+32)

AC = x+50-x-32

AC = 18

The investment in  Fund B is $2000.

To understand the given question we first have to understand the logic of percentage and how it affect the return on Investment.

If an investment fund returns a profit on an investment then the profit is calculated by multiplying the investment with the profit(in decimal form).

For Example: If the investment is A and profit is x % then the profit is calculated by:

Profit =A×([tex]\frac{x}{100}[/tex])

Now in the given problem, let us consider the amount of investment into the Fund B be x.

Profit in Fund B=10%

Profit in Fund A is 3%.

Investment in Fund A=$5000

Total profit from both investments=3% of 5000+10% of x

[tex]=\frac{3}{100}\times 5000 + \frac{10}{100}\times x\\ =150+0.1x[/tex]

Now the total investment=5000+x

The combined profit for both the Investments is 150+0.1x

But the combined profit is 5% for both investments.

profit=[tex]5\% of(5000+x)[/tex]

[tex]=\frac{5}{100}\times (5000+x)\\=0.05\times5000+0.05x\\=250+0.05x[/tex]

Now the profit is same, so if we equate both the expressions of profit we get a linear equation in x.

[tex]\therefore 250+0.05x=150+0.1x\\or,250-150=0.1x-0.05x\\or,100=0.05x\\or,x=2000[/tex]

Thus we can conclude that she invested $2000 in the Fund B.

The ratio of EQUATION the outcome is (17/6)/(8/10) = 3.5416667.

The quotient is the result of dividing two numbers by each other. As in the case of 8 4 = 2, when the division produced the number 2, the outcome is the quotient. The dividend is 8 and the divisor is 4.

based on the available facts;

Divide: 17/6 : 8/10

= 17/6· 10/8

= 17 · 10/6 · 8

= 170/48

= 85/ 24

= 85/24

When two fractions are divided, the first fraction is multiplied by the second fraction's reciprocal value. Finding the reciprocal of the second fraction is the first sub-step. For example, the reciprocal of 8/10 is 10/8. Multiply the two numerators after that. Multiply the two denominators after that. The intermediate step that comes after canceling by a common factor of 2 yields 85/24.

The midpoint of the line segment of the endpoints (6,-6) and (1,2) is given as:

(3½,-1)

What is the midpoint of a line segment in geometry?

The midpoint of a line segment is simply the centre point of a give segment that cuts or divides it into two congruent segments.

That is for example, if there are two points with coordinates (x1,y1) and (x2,y2), then their midpoint will be ; [(x1+x2)÷2,(y1+y2)÷2]

From the given question!

x1=6, x2=1 and y1=-6,y2=2

Thus, the midpoint is derived as;

[(6+1)÷2,(-6+2)÷2]

[(7)÷2,(-4)÷2]

Linear equations are equations that have constant average rates of change. Note that the constant average rates of change can also be regarded as the slope or the gradient

The given parameters are

Slope, m = 1/2

Points (x1, y1) = (x, 5) and (x2, y2) = (3, 3)

The slope of a linear equation is calculated as

m = (y2 - y1)/(x2 - x1)

So, we have

1/2 = (3- 5)/(3 - x)

Evaluate the differences

So, we have

1/2 = -2/(3 - x)

Cross multiply

So, we have

3 - x = -4

This gives

x = 3 + 4

Evaluate the sum

x = 7
