Step-by-step explanation:

Answer:

A) 3.44 ft²

Step-by-step explanation:

before cutouts, the area was 4 x 4 = 16 ft²

the circles have a diameter of 2 ft each, and a radius of 1 ft

each circle has an area pf (3.14)(1²) = 3.14 ft²

3.14 x 4 = 12.56 ft²

16 - 12.56 = 3.44 ft² left

Answer:

x = 8

Step-by-step explanation:

0.4x - 1.2 = 0.15x + 0.8

0.4x - 1.2 + 1.2 = 0.4x

0.15x + 0.8 + 1.2 = 0.15x + 2

0.4x = 0.15x + 2

0.4x - 0.15x = 0.25x

0.15x + 2 - 0.15x = 2

0.25x = 2

0.25x / 0.25 = x

2 / 0.25 = 8

x = 8

Answer and Step-by-step explanation:

It is 3 dollar per pound.

To figure this out, you would have to divide each number by 8. This reduces 8 pounds to 1 pound, and 24 dollars to 3 dollars.

Answer: C

Step-by-step explanation:

At a = 2 and b = -3, the correct expression which has the largest value is,

⇒ 2a - 3b

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The expressions are,

A. 2a+3b

B. 3a+2b

C. 2a-3b

D. 3a-2b

Put a = 2 and b = - 3 in expressions as;

A. 2a + 3b

⇒ 2 × 2 + 3 × - 3

⇒ 4 - 9

⇒ - 5

B. 3a+2b

⇒ 3 × 2 + 2 × - 3

⇒ 6 - 6

⇒ 0

C. 2a-3b

⇒ 2 × 2 - 3 × - 3

⇒ 4 + 9

⇒ 13

D. 3a-2b

⇒ 3 × 2 - 2 × - 3

⇒ 6 + 6

⇒ 12

Thus, Option C has the largest value.

Answer:

Option (2)

Step-by-step explanation:

Amount of apples in a box = [tex]2\frac{3}{4}[/tex] pounds

                                            = [tex]\frac{11}{4}[/tex] pounds

Apples used by Sage = [tex]\frac{1}{5}th[/tex] Part of the total amount

                                    = [tex]\frac{1}{5}[/tex]th part of the apples in the box

                                    = [tex]\frac{1}{5}\times \frac{11}{4}[/tex]

                                    = [tex]\frac{11}{20}[/tex] pounds

Therefore, Sage used [tex]\frac{11}{20}[/tex] pounds of the apples.

Option (2) will be the answer.

Answer:

[tex]\Sigma_{k=1}^{n}[3(\frac{10}{9} )^{k-1}][/tex]

Step-by-step explanation:

A geometric sequence is a list of numbers having a common ratio. Each term after the first is gotten by multiplying the previous one by the common ratio.

The first term is denoted by a and the common ratio is denoted by r.

A geometric sequence has the form:

a, ar, ar², ar³, . . .

The nth term of a geometric sequence is [tex]ar^{n-1}[/tex]

Therefore the sum of the first n terms is:

[tex]\Sigma_{k=1}^{n}(ar^{k-1})[/tex]

Given a geometric series with a first term of 3 and a common ratio of 10/9, the sum of the first n terms is:

[tex]\Sigma_{k=1}^{n}[3(\frac{10}{9} )^{k-1}][/tex]

Answer:

56 cent per ft²

Step-by-step explanation:

Wall dimension = 35 feets * 21.5 feets

Total cost of paint used = 421.40

Area of wall = Area of rectangle = Length * width

Area of wall = 35 feets * 21.5 feets

Area of wall = 752.5 ft²

Cost of paint per square feet:

Total coast of paint / Area of wall

$421.40 / 752.5 ft²

= $0.56 per ft²

= 0.56 * 100 = 56

Answer:

Formula for Volume of Cylinder = pi x r^2 x h

Volume = 3.14159 x 7^2 x 3

Volume  = 461.81373 in^3

Volume  = 461.8 in^3

Answer:

6 cups

Step-by-step explanation:

Recall:

1 pint = 2 cups

Required recipe = 3 pints of rice

To make the measurement using a cup ;

The number of cups of rice needed will be ;

1 pint = 2 cups

3 pints = x cups

Cross multiply

x = 3 *2

x = 6

Hence, 6 cups of rice will be needed

Answer:

the car is traveling 60 miles per hour

Step-by-step explanation:

Since it is going 30 miles in half an hour, we just need to double both values to find the speed for an hour

30*2=60

1/2*2=1

60 miles per hour

Answer:

Volume of the given pyramid = 1122.37 cubic feet

Step-by-step explanation:

Volume of the regular hexagonal pyramid = [tex]\frac{1}{3}(\text{Area of the base})(\text{Base})[/tex]

Measure of internal angle of a polygon = [tex]\frac{(n-2)\times 180}{n}[/tex]

Here, n = number of sides of the polygon

For a hexagon, n = 6

Measure of interior ∠C = [tex]\frac{(6-2)\times 180}{6}[/tex]

                                       = 120°

Measure of ∠BCD = [tex]\frac{120}{2}[/tex]

                              = 60°

By applying tangent rule in ΔCED,

tan(∠ECD) = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]

tan(60°) = [tex]\frac{DE}{CE}[/tex]

[tex]\sqrt{3}=\frac{DE}{6}[/tex]

DE = [tex]6\sqrt{3}[/tex] feet

And cos(60°) = [tex]\frac{EC}{CD}[/tex]

[tex]\frac{1}{2}=\frac{6}{CD}[/tex]

CD = 12 feet

Area of ΔBCD = [tex]\frac{1}{2}(\text{Base})(\text{Height})[/tex]

                        =  [tex]\frac{1}{2}(6\sqrt{3})(12)[/tex]

                        = [tex]36\sqrt{3}[/tex] feet

Area of hexagonal Base of the pyramid = [tex]6(36\sqrt{3})[/tex]

                                                                  = 216√3 square feet

Since, lateral height of the pyramid (AC) = 15 feet

By applying Pythagoras theorem in ΔADC,

AC² = AD² + CD²

(15)² = AD² + (12)²

AD = [tex]\sqrt{225-144}[/tex]

AD = 9 feet

Volume of the given pyramid = [tex]\frac{1}{3}(216\sqrt{3})(9)[/tex]

                                                 = 648√3 cubic feet

                                                 = 1122.37 cubic feet

Answer:

1/7 > 1/8

Step-by-step explanation:

In fractions, is the numerator is one on both numbers, then whichever denominator is largest means the fraction is the smallest.

Answer:

Write the problem as a mathematical expression.

y=−x²+18x−72

Rewrite the equation in vertex form.

y=−(x−9)²+9

Use the vertex form, y=a(x−h)2+k , to determine the values of a, h, and k.

a=−1

h=9

k=9

Find the vertex (h,k).

Answer:

4 numbers, mean of 5.

4x5= 20. so the total of all 4 numbers is 20.

2+4+6= 12

so in order for the total to be 20, the missing number has

to be 8 (20-12=8)
