I’m having trouble on this, can someone help?

Answer:

B

Step-by-step explanation:

Notice that the y intercept is 125 and that each time week it goes down by 25 meaning the slope is equal to -25

this means our equation is

-25x+125=y which is the same as b

Answer:

C x=40, y=30

Step-by-step explanation:

Remember the opposite side of parallelogram is the same

so angle C and angle A is the same.

3x=120

divide both sides by 3 and you get 40

All parallelogram equal to 180 degrees so to find y

180=2y+120

-2y=120-180

-2y=-60                   negative divide negative is positive.

y=30

Answer:

28

Step-by-step explanation

180=85+67+x

x=28

Kindly find number line in attacked picture

Step-by-step explanation:

Price of cupcake per dozen = $15

Projected amount of sales > $120

In other to make such amount in sale, we need to obtain the number of dozens of cupcake :

Project amount of sales / price per dozen

> $120 / $15

> 8 dozens

Answer: Hence, Mean height of the girls is: 1.48

Step-by-step explanation: It is given that:

in a class of 32 students .

the mean height of 14 boys is 1.56 and the mean height of all 32 students is 1.515.

Since there are 14 boys in a class.

So, number of girls is equal to (32-14)=18.

The mean height of 14 boys is 1.56.

Hence the sum of height of 14 boys is= 1.56×14=21.84

Similarly mean height of 32 students is 1.515.

Hence, sum of height of 32 students=1.515×32=48.48.

Let x denote the mean height of 18 girls.

Hence, sum of height of 18 girls is: 18 x.

Now,

18x+21.84=48.48

( since sum of height of girls and boys is equal to the sum of height of all the students)

so, 18x=48.48-21.84

18 x=26.64

Hence, x=1.48

Hence, Mean height of the girls is: 1.48

Answer:

25 is the total length

Step-by-step explanation:

Distance driven = 15

Which Is 3/5 of the way home

Total length of drive

The unknown = x which is the total length of his drive

From the statement in this question 15 is three-fifth of c

So we have this equation:

(3/5)x = 15

We divide both sides by (5/3) so that x can stand on its own

(3/5)(5/3)x = 15(5/3)

(15/15)x = 75/3

x = 25

The total length of the drive is 25

Step-by-step explanation:

Find 5% of £16855.21 by 3.5%

5%=842.7605

1%=168.5521

0.5%=84.27605

168.5521+168.5521+168.5521+84.27605=

£16855.21-589.93235 =16265.27765

16265.28 is the answer rounded to 2dp

Answer:

Drew is incorrect

Step-by-step explanation:

Drew is incorrect

Let the number be x such that if the product of the number and four is 1.08 then

x * 4 = 1.08

Divide both sides by 4

x = 1.08/4

= 0.27

Drew is incorrect because the result (1.08) has 2 decimal places and not once as deduced by him hence the number of digits before the decimal point for the numbers being multiplied must be 2.

The answer is below

Step-by-step explanation:

A rectangle has an area of x² + 7x + 12. Use factoring to find possible dimensions of the rectangle. Explain why you can use factoring to find the answer.

Solution:

A rectangle is a quadrilateral (ha four sides and four angles) in which opposite sides are parallel and equal to each other. All the four angles in a rectangle are 90° each.

The area of a rectangle is given by:

Area = length * width

Hence the area is the product of two sides.

Given that:

Area = x² + 7x + 12

Factoring to find both the length and width of the rectangle:

Area = x² + 7x + 12

Area = x² + 4x + 3x + 12

Area = x(x + 4) + 3(x + 4)

Area = (x + 4)(x + 3)

After factoring we can see that the area is the product of (x + 4) and (x + 3). Hence x + 4 is the length and x + 3 is the width.

Step-by-step explanation:

Area of square = s² ; s = side length

Let the area of each room equal to x and y

x + y = 89cm²

If x = smaller room

y = x + 3 in dimension

Hence,

x² + (x + 3)² = 89

(x +3)(x +3) = x² + 3x + 3x + 9

x² + x² + 3x + 3x + 9 = 89

2x² + 6x + 9 = 89

2x² + 6x - 80 = 0

x² + 3x - 40 = 0

x² + 8x - 5x - 40 = 0

x(x + 8) - 5(x + 8) = 0

x + 8 = 0 ;

x - 5 = 0

x = - 8 or x = 5

Dimension can't be negative :

So, x = 5

Samller square = x = 5

Larger square = x + 3 = 5 + 3 = 8

Answer:

b. x > -6

Step-by-step explanation:

> [greater than], and < [less than] inequalities are not filled in because the value is not included, but is only greater or less than.

≥ [greater than or equal to], and ≤ [less than or equal to] inequalities are filled in because the value is included, and it is greater than or less than.

Given that there is an empty circle with an arrow moving in the positive direction from -6, the inequality must be a greater than, and since the value is -6, x > -6.

Answer:

10

Step-by-step explanation:

We will first take a right triangle and we will apply the pythagorean theorem to it. First, the base of the right triangle will be 12/2 which is 6; then, we will just use the theorem.

a^2+b^2 = c^2 (pythagorean theorem)

8^2+6^2 = c^2

100 = c^2

c = 10 because the square root of 100 is 10
