Step-by-step explanation:

Area = 182 m^2

Perimeter = 54 m

Solution.

B: solves for the length, not the width. Area = L*w. Area / w = L. But to get to the length, you need to solve for the width. So this statement can be used. B is true.

C is not true. The length and width differ by 1 which means one of them is even and the other is odd. See below under A.

D is also true. 2L = 54 - 2w   Divide both sides by 2

2L/2 = 54/2 - 2w/2

L = 27 - w

E is true.

L * w = 182                              Divide both sides by w

L = 182/w

The only one we don't know about is A. We have to solve the problem to get the answer to A.

P= 2L + 2w = 54

2L + 2w = 54

L + w = 27

L = 27 - w

L*w = 182

(27 - w ) * w  = 182                   Remove the brackets

27w - w^2 = 182                      Subtract 27w - w^2  from both sides.

0 = w^2 - 27w + 182                Notice the sign change. Subtraction does that.

This factors into

(w - 13)(w - 14)

A turns out to be true, because w can be 13 or 14. When W = 13, L = 14.

When w = 14, L = 13

Work Shown:

12 & 1/2 = 12 + 1/2 = 12 + 0.5 = 12.5

Jerry climbed 250 steps in 12.5 minutes

unit rate = (250 steps)/(12.5 min)

unit rate = (250/12.5) steps per min

unit rate = 20 steps per min

The unit rate is basically the same as the average speed.

Here, we are given the cost of Jose for 1 year for attending college i.e $14500/year, and we need to find the total cost for Jose to attend college for 4 years, so here we can just use unitary method, we can just multiply the whole cost for 1 year by 4, to get the total cost for 4 years, as :

[tex]{:\implies \quad \sf Cost\:\: for\:\: 1\:\: year= \$14500}[/tex]

Now, multiplying by 4 on both sides will yield :

[tex]{:\implies \quad \sf Cost\:\: for\:\: 4\:\: years= \$14500\times 4}[/tex]

[tex]{:\implies \quad \boxed{\bf{Cost\:\: for\:\: 4\:\: years= \$58000}}}[/tex]

This is the required answer

The total cost of tuition, books, and fees for Jose if he eventually chooses to attend this college for four years is $58,000.

Using this formula

Total cost of tuition=Cost of tuition books and fees×Number of years

Where:

Cost of tuition books and fees=$14,500 per year

Number of years=4 years

Let plug in the formula

Total cost of tuition=$14,500 per year x 4 year

Total cost of tuition=$58,000

Inconclusion the total cost of tuition, books, and fees for Jose if he eventually chooses to attend this college for four years is $58,000.

The volume of air needed is equal to the volume of the sphere, which is 7,234.56 cm^3.

The volume of air that we need is equal to the volume of the basketball.

Remember that for a sphere of radius R, the volume is:

V = (4/3)*3.14*R^3

In this case, the radius is 12cm, replacing that we get:

V = (4/3)*3.14*(12cm)^3 = 7,234.56 cm^3

Then, to fully inflate the ball, we need  7,234.56 cm^3 of air.

Step-by-step explanation:

First, find the common denominator between 3/4 and 1/10. If you multiply 1/10 by 2/2 you get 2/20. If you multiply 3/4 by 5/5 you get 15/20. Now that we have the common denominator, how many times can 2/20 go into 15/20? Since 2 x 7 = 14, the answer is 7.

Answer:

200 questions

Step-by-step explanation:

Here,

grade = 36%

total number of question = ?(X)

We know,

36% of X = 72

or, 36x/100 = 72

or, 36x = 72*100

or, x = 7200/36

Q=91, S = 153

Step-by-step explanation:

QR and TS are parallel (see the arrows in the middle?). Means that angles T and Q add up to 180 - they are conjugate angles. Thus Q has to be 89 (since 89+91=180).
Same difference for R and S: they add up to 180 and since one is 27, the other has to be 153.

Answer:

955.168 cm²

Step-by-step explanation:

The formula to find the surface area of a cylinder is :

Surface area = 2 π r ( r +  h )

Here,

r ⇒ radius ⇒ 8 cm

h ⇒ height ⇒ 11 cm

So, Let us solve now.

Surface area = 2 π r ( r +  h )

Surface area  = 2 × 3.142 × 8 ( 8 + 11 )

Surface area  = 50.272 × 19

Surface area  = 955.168 cm²

Answer:

(x - 1)2 + (y + 2)2= 25

Step-by-step explanation:

because that is it

The values of the x when the square root is taken on both sides are negative 4 and negative 14.

Algebra is the study of mathematical symbols and the rule involves manipulating these mathematical symbols.

The equation is given below.

(x + 9)² = 25

Taking square root on both sides, then we have

(x + 9) = ±5

When the positive sign is considered, then we have

x + 9 = 5

     x = -4

When the negative sign is considered, then we have

x + 9 = -5

     x = -14
