Answer and explain? I've been getting a lot of these questions wrong lately lol.

Answers

Answer 1

Answer:

the answer is 31!

Step-by-step explanation:

So if you do 12 x 3 that is 36 and 36-5 is 31

so then you see if it works

31 +5 = 36

36/3 = 12

Answer 2

Answer:

number: 31

Let the number be x

This number is added by 5, so: x + 5

Then we divide it total by 3, so: (x + 5)/3

And this equals to 12, (x + 5)/3 = 12

Solve for unknown number:

(x + 5)/3 = 12

x + 5 = 36

x = 36 - 5

x = 31

find x

Answers

Answer:

Step-by-step explanation:

the measure of a secant- tangent angle is half the difference of the intercepted arcs, then

[tex]\frac{1}{2}[/tex] (154 - (12x + 2) ) = 6x + 4 ( multiply both sides by 2 to clear the fraction )

154 - 12x - 2 = 12x + 8 , that is

152 - 12x = 12x + 8 ( subtract 12x from both sides )

152 - 24x = 8 ( subtract 152 from both sides )

- 24x = - 144 ( divide both sides by - 24 )

Mr. Ingle purchased a Prius for $42,500. If the car depreciates at a rate of 10%, what is
the value of the car after 7 years?

Answers

Based on the cost of Mr. Ingle's car and the depreciation rate, the value after 7 years will be $20,327.62.

What would be the value after 7 years?

This can be found by the formula:

= Cost of car x ( 1 - depreciation rate) ^ number of years given

Solving gives:

= 42,500 x (1 - 10%)⁷

= 42,500 x 0.4782969

= $20,327.62

clockwise about the origin and then translated
2 units left and 3 units down to form A'B'C'D'.
What is the length, in units, of line segment A'B'
if AB was 4 units?

Answers

Rotation involves moving the rectangle ABCD around a fixed point

The length of side A'B' is 4 units, if AB was 4 units

How to determine the length of A'B'

From the question, we have the following transformations

RotationTranslation

Both transformations are rigid transformations, and they do not change the length of the shape

Hence, the length of side A'B' is 4 units, if AB was 4 units

14. Danny works part-time at Tom's Toy Store. He
worked 84 hours in May and June. Danny worked
one-third as many hours in May as in June.
How many hours did he work in each month?

Answers

Answer:

21 hours in May, 63 hours in June

Step-by-step explanation:

Set up equationsm - May, j - Junem + j = 84m = 1/3jSolve by substitution, fin the value of j1/3j + j = 844/3j = 84j = 84*3/4j = 63Find mm + 63 = 84m = 84 - 63m = 21

May be y and June be x

x+y=84y=1/3x

Now

Put y from (2) in eq(1)

x+1/3x=843x+x)3=844x/3=844x=3(84)x=3(21)x=63

Find y

y=1/3(63)y=21

Juan is clearing land in the shape of a circle to plant a new tree. The diameter of the space he needs to clear is 52 inches. By midday, he has cleared a sector of the land cut off by a central angle of 140 . What is the arc length and the area of land he has cleared by midday?

Answers

The central angle of 140 degrees illustrates the degree measure of the arc

The arc length cleared is 63.54 inches and the area of the land cleared is 826.00 square inches

How to determine the arc length

The given parameters are:

Central angle = 140 degrees

Diameter = 52 inches

The length of the arc is then calculated s:

[tex]L = \frac{\theta}{360} * \pi d[/tex]

Substitute known values in the equation

[tex]L = \frac{140}{360} * 3.142 * 52[/tex]

Evaluate the products

[tex]L = \frac{22873.76}{360}[/tex]

Evaluate the quotient

[tex]L = 63.54[/tex]

Hence, the arc length cleared is 63.54 inches

How to determine the area of the land cleared

The area is calculated s:

[tex]A = \frac{\theta}{360} * \pi (d/2)^2[/tex]

Substitute known values in the equation

[tex]A = \frac{140}{360} * 3.142 * (52/2)^2[/tex]

Evaluate the products

[tex]A = \frac{297358.88}{360}[/tex]

Evaluate the quotient

[tex]A = 826.00[/tex]

Hence, the area of the land cleared is 826.00 square inches

At a fabric store, fabrics are sold by the yard. A dressmaker spent $36.35 on 4.25 yards of silk and cotton fabrics for a dress. Silk is $16.90 per yard and cotton is $4 per yard.
Let 'x' represent the number of yards of silk and 'y' represent the number of yards of cotton.
Here is a system of equations that represent the constraints in the situation.
x+y=4.25
16.90x+4y=36.35
Find the solution to the system of equations. You may use any method you want, but you must explain your reasoning and methods fully.

Answers

Answer:

Step-by-step explanation:

The yards of silk bought is 1.49 yards and the yard of cotton bought is 2.76 yards.

The two equations are known as simultaneous equation. They would be solved using elimination method.

x + y = 4.25 equation 1

16.90x + 4y = 36.25 equation 2

where:

x = yards of silk bought

y = yards of cotton bought

In order to determine the value of x, multiply equation 1 by 4.

4x + 4y = 17 equation 3

Subtract equation 3 from 2

19.25 = 12.90x

Divide both sides of the equation by 12.90

x = 1.49 yards

In order to determine the value of y, substitute for x in equation 1

1.49 + y = 4.25

y = 4.25 - 1.49

y = 2.76 yards

Answer:

Step-by-step explanation:

The yards of silk bought is 1.49 yards and the yard of cotton bought is 2.76 yards.

16.90x + 4y = 36.25 equation 2

In order to determine the value of x, multiply equation 1 by 4.

4x + 4y = 17 equation 3

Divide both sides of the equation by 12.90

x = 1.49 yards

What is a graph?

A graph is a way to represent a lot of data in such a visual format that it is easy for the user to understand the complete information in one go. Usually, the line of the graph is a function that follows the graph.

here, we have,

A.) A symmetric graph is a graph in which the left half of the graph looks like the mirror image of the right half of the graph. Since the graph has no symmetry it is not a symmetric graph.

B.) Skewness is a distortion or asymmetry in a set of data that deviates from the symmetrical bell curve, or normal distribution. The curve is said to be skewed if it is displaced to the left or right. As we can see that the shape of the graph is the left tilted bell shape.

C.) A constant graph is a graph in which the value of each bar lies on the same horizontal value. Since the shape of the graph is not a horizontal line, it is not a constant shape graph.

D.) When a graph has Peak and Valleys in a graph, the values of the graph are different from each other, therefore, forming peaks and valleys in a graph, which looks like a spline. Since the value of the graph is decreasing towards the right side of the graph. Therefore, the graph of the shape is not of a peak and valley.

Thus, the shape of this graph is best described as skewed.

second sample indicates that only 15% of the trees are oak. The third sample

indicates that 26% of the trees are oak. The fourth sample indicates that 29% of

Answers

Using proportions, it is found that about 175 trees are oak.

What is a proportion?

A proportion is a fraction of a total amount.

For the four samples, the proportions are: {0.3, 0.15, 0.26, 0.29}.

Hence, the mean proportion is given by:

M = (0.3 + 0.15 + 0.26 + 0.29)/4 = 0.25

Out of 700 trees:

700 x 0.25 = 175.

About 175 trees are oak.
