HELP!Find The Measure For A)127B)131C)135D)139

Answers

Answer 1

Answer:

B) 131°

Step-by-step explanation:

-4a + 139 = 4a + 123 because they are vertical angles

-4a + 139 = 4a + 123

reduce:

8a = 16

a = 2

4(2) + 123 = 131°

ASAP!: can anyone solve three times the difference of Federico age and 4 increased by 7 is greater than 37 what are possible values of Federico age?

Answers

Answer:

Federcio's age possible values are those that are greater than 14 i.e 15, 16, 17 and so on

Step-by-step explanation:

Let Federico's age = x

Three times the difference of Federico’s age, and 4 means:

3(x - 4)

Increased by 7:

3(x - 4) + 7

Is greater than 37:

3(x - 4) + 7 > 37

Solving the inequality:

3x - 12 + 7 > 37

3x - 5 > 37

3x > 37 + 5

3x > 42

x >42/3

x > 14

Federcio's age possible values are those that are greater than 14

The youth soccer team is fundraising by washing cars. They paid $84.55 for supplies. If
they charge $8.00 per wash, how many cars must be washed to profit at least $300.00 dollars?

Answers

Answer:

The soccer team must wash 49 cars in order to gain at least $300.

Step-by-step explanation:

The soccer team started out by paying $84.55.  They charge $8 per car wash.  So let's say how many cars they washed was x.  They need to gain at least $300 dollars.  If we put this in an equation it looks like this (we are solving for x):

8x - 84.55 >or= 300

To find x we have to do the following steps:

8x - 84.55 >= 300

    + 84.55     + 84.55

8x >= 384.55

/8          /8

x >= 48

Now we have to make sure that this is correct:

8 * 48 - 84.55 = ?

384 - 84.55 = 299.45

Since 299.45 is less than 300, x must be greater than 48, but since 299.45 is so close to 300, my educated guess would be that x=49.  

8 * 49 - 84.55 = ?

392 - 84.55 = 307.45

Since 307.45 is greater than 300, x=49.  So we can conclude that they must wash 49 cars to profit at least $300.

Given the 2 similar triangles, what is the length of LK?

What is -6x+4(-2x+8y)-2y+4

Answers

Answer:

-14x + 30y + 4

Step-by-step explanation:

-6x + 4(-2x + 8y) - 2y + 4

take out the parentheses

4(-2x + 8y) = -8x + 32y

-6x - 8x + 32y - 2y + 4

solve for the x's then y's

-6x - 8x = -14x

32y - 2y = 30y

you are done

-14x + 30y + 4

The roof of a clock tower is a square pyramid. Each side of the base is 16ft long. The slant height is 22ft. What is the lateral area of the roof?

Answers

Answer:

The area of the pyramid is 703.97 ft²

Step-by-step explanation:

The lateral area of a right square pyramid is given as;

[tex]A_l =a \sqrt{a^2 + 4h^2}[/tex]

where;

a is base length

h is the vertical height of the pyramid

The vertical height of the pyramid is calculated as follows;

the vertical height passes through the center of the base.

half of the base = 8 ft

the slant height = hypotenuse side of the right triangle = 22 ft

Thus; h² = 22² - 8²

h² = 420

h = √420

h = 20.493 ft

The area of the pyramid is calculated as;

[tex]A_l =a \sqrt{a^2 + 4h^2}\\\\A_l =16\sqrt{16^2 + 4(20.493)^2} \\\\A_l = 703.97 \ ft^2[/tex]

Therefore, the area of the pyramid is 703.97 ft²

The quotient of 50 and 5 subtracted from 20 (move numbers and symbols to the line to show the phrase as a numerical expression)

Answers

The value of the quotient of 50 and 5 subtracted from 20 that can be given as 10.

What is subtraction?

It simply means to deduct something from the object or number of group, place, etc. Subtraction means to take away from the group or a number of objects.

Firstly, we have the quotient of 50 and 5. This can be written as

[tex]\dfrac{50}{5}[/tex]

And we know that this can be written as 10.

Now we subtract it from 20. Then we have the number 20 and we subtract 10 from it. Then it can be written as

20 - 10

On subtracting, we have

20 - 10 = 10.

Answers

Answer:

[tex]Area = 49\frac{25}{36}[/tex]

Step-by-step explanation:

Given

Tile

[tex]Length = 4\frac{5}{6}[/tex]

[tex]Width = 2\frac{1}{3}[/tex]

See attachment for dimension of the floor

Required

Determine the area covered by the carpet

From the attachment, the dimension of the floor is:

[tex]Length = 12\frac{1}{4}[/tex]

[tex]Width = 5[/tex]

Calculate Area

[tex]Area = Length * Width[/tex]

[tex]Area = 12\frac{1}{4} * 5[/tex]

[tex]Area = 61\frac{1}{4}[/tex]

The area of the tiles is:

[tex]Area = 4\frac{5}{6} * 2\frac{1}{3}[/tex]

[tex]Area = \frac{29}{6} * \frac{7}{3}[/tex]

[tex]Area = \frac{203}{18}[/tex]

[tex]Area = 11\frac{5}{18}[/tex]

So, the carpet area is:

[tex]Area = Floor\ Area - Tile\ Area[/tex]

[tex]Area = 61\frac{1}{4} - 11\frac{5}{18}[/tex]

To improper number

[tex]Area = \frac{245}{4} - \frac{208}{18}[/tex]

Take LCM

[tex]Area = \frac{2205 - 416}{36}[/tex]

[tex]Area = \frac{1789}{36}[/tex]

[tex]Area = 49\frac{25}{36}[/tex]

B [tex]\hat y=20x+20[/tex]

C [tex]\hat y=-20x+20[/tex]

Based on this equation, estimate the score for a student that spent 3.8 hours studying.

Answer:

[tex]\hat y = 20x +20[/tex]

Score of 96 for studying 3.8 hours

Step-by-step explanation:

Given

See attachment for graph

From the straight line of trend, we have:

[tex](x_1,y_1) = (0,20)[/tex]

[tex](x_2,y_2) = (2,60)[/tex]

The slope (m) is:

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

[tex]m = \frac{60 - 20}{2 - 0}[/tex]

[tex]m = \frac{40}{2}[/tex]

[tex]m = 20[/tex]

The equation is calculated using:

[tex]\hat y = m(x - x_1) + y_1[/tex]

This gives:

[tex]\hat y = 20(x - 0) +20[/tex]

[tex]\hat y = 20(x ) +20[/tex]

[tex]\hat y = 20x +20[/tex]

Solving (b): When study hours is 3.8

This means that [tex]x= 3.8[/tex]

So:

[tex]\hat y = 20x +20[/tex]

[tex]\hat y = 20 * 3.8 + 20[/tex]

[tex]\hat y = 96[/tex]
