Step-by-step explanation:

Hey There. Your Answers Are A. And D.

Step-by-step explanation:

Answer:

x = 16.20

Step-by-step explanation:

tan48 = 18/x

xtan48 = 18

x = 18/tan48

x = 16.20

Answer:

35

Step-by-step explanation:

When the two lines being crossed are Parallel Lines the Consecutive Interior Angles add up to 180°.

So, x + 12 + 4x - 7 = 180.

5x + 5 = 180

5x = 175

x = 35

Answer:

f(x)=

[tex] {x}^{2} + 8[/tex]

or

Answer:

g(x) = (x-4)^2

Step-by-step explanation:

Just took the test and got it right. SEE picture for answer.

Answer:

Step-by-step explanation:

Y = 1/4x - 12

Adding 12 on both sides

12y = 1/4x

12y/ 1/4 = x

3y = x

messed up, thought it said 2 lol ignore my answer

Answer:

-3x + 7

Step-by-step explanation:

she used the y-intercept as the slope and the slope as the y- intercept.

Answer:

its y= -3x+7

Step-by-step explanation:

she used the x intercept for the y - intercept and the y- intercept for the c-intercept

Answer:

y= 2x+1

Step-by-step explanation:

Using the general linear form y=mx+c

First find the gradient: change in y/change in x

11-5/6-2 = 6/3= 2

y=2x+c

Secondly find out c:

Use one of the coordinats

5= 2(2)+c

5=4+c

-4

1=c

y= 2x+1

Step-by-step explanation:

x= -3, -7

Answer:

x = -7, -3

Step-by-step explanation:

Try to factor the left side of the equation.  

(x +7)(x + 3) = 0    Remember that if AB = 0, then A = 0 or B = 0 or both  A and B = 0

Therefore,  x + 7 = 0  or x + 3 = 0

                        x = -7  or x = -3

Answer:

6 cm

Step-by-step explanation:

Area of parallelogram = 75 sq.cm

base * height = 75

12.5 * height = 75

          height = 75÷ 12.5

height = 6 cm

Answer:

Answer:

x=216°

Step-by-step explanation:

100%=360°

To find 10% divide by 10

10%=36°

x4

40%=144°

in a full circle thered 360°

360-144=216°

x=216°

Answer:

Answer:

the x would equal to 11 ,so x=11

The formula to calculate mean= Add the numbers and Divide by how many numbers( there are 7 numbers)..............

If the answer is wrong.....

Sorry, because I read in class nine........

Answer:

there's nothing in step 1

it's not clear enough

Answer:

Step-by-step explanation:

Let us represent:

Short pieces = x

Middle pieces = y

Long pieces = z

A three foot long deli sandwich must be split into three pieces

x + y + z = 3

The middle piece is twice as long as the shortest piece

y = 2x

The shortest piece is 8 inches shorter than the longest piece.

x = z - 8

z = x + 8

We substitute

x + y + z = 3

x + 2x + x + 8 = 3

5x = 8 - 3

5x = 5

x = 5/5

x = 1

y = 2x

y = 2 × 1

y = 2

z = x + 8

z = 1 + 8

z = 7

How long should the three pieces be?

Answer:

Step-by-step explanation:

Consider AP:

As multiples of 5 between 100 and 300

The first term is 105, the common difference is 5, the last term is 295.

Use the nth term formula:

Answer:

Solution given:

first term [a]=100

last term[l]=300

common difference [d]=5

second term[b]=100+5=105

now

we have

l=a+(n-1)d

substituting value

300=100+(n-1)5

300-100=(n-1)5

200/5=n-1

40=n-1

n=40+1

there are 41 multiple in between 100 and 300/including it but no including its 41-2=39 multiple

Answer:

c.15

Step-by-step explanation:

3*35= 105

since 7x=105 you divide 105 by 7 which is 15

Answer:

7x=3y

7x=3(35)

7x=105

x=105/7

x=15

Answer: 2000

Step-by-step explanation:

From the information, we are informed that a population of 500 doubles in size every 80 years. Therefore, the population in 160 years will have doubled twice i.e 160/80 = 2 times

First time doubling = 500 × 2 = 1000

Second time doubling = 1000 × 2 = 2000

Answer:

[tex]\displaystyle t=\frac{v-v_o}{a}[/tex]

Step-by-step explanation:

Equations

It's given that the velocity (v) of an object is equal to its initial velocity (vo) plus the product of its acceleration (a) and the elapsed time (t).

The equation that expresses the above relationship is

[tex]v =v_o+at[/tex]

We must write an equation that expresses time in terms of the rest of the variables given above.

Swap the equation:

[tex]v_o+at=v[/tex]

Subtract vo:

[tex]at=v-v_o[/tex]

Divide by a:

[tex]\boxed{\displaystyle t=\frac{v-v_o}{a}}[/tex]

Answer:

36

Step-by-step explanation:

it says 6 with a 2 so u multiply 6 by 2 and get 12 then u multiply the 12 by the 3 and get 36 SO SRY IF IM WRONG !!

Answer:

Option (3)

Step-by-step explanation:

Formula to calculate the surface area of a cardboard box in the shape of a cube is,

Surface area = 6(Side)²

If the length of the each side of the box is = 3 feet

Surface area of the cube = 6(3)²

                                          = 6 × 9

                                           = 54 square feet

Therefore, Surface area of the box in the shape of a cube is 54 square feet.

Option (3) is the correct option.

Answer:

hii

Step-by-step explanation:

interior corner of the triangle is 180°

180° - 78° - 90° = 12°

x = 12°

2y - 1 = 24

2y = 24 + 1

y = 25/2

y = 12.5

Answer:

Answer:

Madison has earned 180 dollars in all.

Step-by-step explanation:

Let [tex]x[/tex] denotes amount earned by Madison.

Percentage of amount saved by Madison [tex]=\frac{40}{100} x[/tex]

Amount saved by Madison [tex]=72[/tex] dollars

Therefore,

[tex]\frac{40}{100}x=72\\x=72(\frac{100}{40})[/tex]

[tex]=180[/tex] dollars

So,

Madison has earned 180 dollars in all.

Answer:

25 I'm pretty sure

Step-by-step explanation:

5×5=25

Answer:

25 cm

Step-by-step explanation:

If it is enlarged by the scale factor of 5, you are multiplying by 5. 5 cm is the longest side, so therefore 5 cm times 5 cm is equal to 25.

Answer:

23.41%

Step-by-step explanation:

Kirtim's purchase price was 3600 + 205 = 3805,

Kirtim sold the table for 4968 for a profit of 4968 - 3805 = 1163

Assuming requirement is for profit on revenue, so

P = 100 * (1163/4968) = 23.41%
