Mrs. Hector is renovating a house. The living room is a rectangle 10 feet long and 15 1/2 feet wide. Mrs. Hector wants to put in new flooring in the living room. Flooring is sold by the square foot for $6.25. How much flooring does she need and how much will it cost? Area = length x width

This is the same as writing [tex]3^9[/tex]

====================================================

How to get that answer:

The lowest height is 3^8, and the highest point is 3 times that value.

We can think of that second "3" as really 3^1. This is because x^1 = x for any real number.

Multiply 3^8 and 3^1 using the rule that a^b*a^c = a^(b+c). We add the exponents together.

Therefore, 3^8*3^1 = 3^(8+1) = 3^9

Side notes:

Answer:

3^9

Step-by-step explanation:

3 * 3^8

3^1 * 3^8

3^1+8

= 3^9

Answer:

V = 7,600.17

Step-by-step explanation:

Given:

V=25000(0.82)^t

Where,

V = value of the car

t = time in years

Find V when t = 6

V = 25,000(0.82)^t

= 25,000(0.82)^6

= 25,000(0.304006671424)

= 7,600.1667856

Approximately

V = 7,600.17

Answer: Your question is poorly written, the Normal Curve is missing attached is a free sketch of normal distribution curve

answer : attached below

Step-by-step explanation:

Given data :

Mean = 80

standard deviation = 10

for a Normal distribution curve to the right of the mean value is ; +10SD , +20SD, +30SD........ +250D while to the left is  -10SD , -20SD, -30SD....... -350D

Answer:

the total payment need to pay is $525

Step-by-step explanation:

Given that

The amount at promissory note issued is $500

The rate of interest is 10%

And, the time period is 180 days

So, the total payment included is

= $500 + ($500 × 10% × 180 days ÷ 360 days)

= $500 + $25

= $525

hence, the total payment need to pay is $525

Answer:

a. Simplify each term. 49/2+0

Add 49/2 and 0.

49/2

The result can be shown in multiple forms.

Exact Form:

49/2

b. Replace the variable a with −13 in the expression.

−(−1/3)²b²−3(−1/3)³b²

Replace the variable b with −1 in the expression.

−(−1/3)²(−1)²−3(−1/3)³(−1)²

Simplify each term. −1/9+1/9 = 0

Combine fractions. 0

Answer:

3.

Step-by-step explanation:

3(n + 4) = 21

3n + 12 = 21

3n = 21 - 12 = 9

n = 3.

Answer:

n = 3

Step-by-step explanation:

Given

3(n + 4) = 21 ( divide both sides by 3 )

n + 4 = 7 ( subtract 4 from both sides )

n = 3

Answer:

630cm³

The volume of the right triangular prism is 630cm³.

Answer:

x ≤ -3 ∨ x ≥ 0

Step-by-step explanation:

3+ 2x ≥ 0

2x ≥ -3

x ≥ -3/2

if x ≥ -3/2

-2x - 3 + 1 ≤ -2

-2x ≤ 0

x ≥ 0

if x ≤ -3/2

2x + 3 + 1 ≤ -2

2x ≤ -6

x ≤ -3

x ≤ -3 ∨ x ≥ 0

Question:

What’s the volume ?

Answer:

Volume: 8663.2

Area : 392

Step-by-step explanation:

The formula for volume is length times width times height (L x W x H)

So

28 x 28 = 784 x 22.1 = 17326.4 (Crazy right) But this is not the answer. A triangle is half of a Square so we divde by 2

17326.4 / 2 = 8663.2

The Volume is 8663.2

And if you are looking for the Area it's 392

Answer:

Curved Surface Area = 48π cm² (≈ 150.72 cm²)

Total Surface Area = 120π cm² (≈ 376.8 cm²)

Step-by-step explanation:

GIVEN :-

TO FIND :-

GENERAL FORMULAES TO BE USED IN THIS QUESTION :-

Curved Surface Area of cylinder = 2πrh

Total surface Area of cylinder = 2πrh + 2πr² = 2πr(h + r)

SOLUTION :-

Curved Surface Area of cylinder = 2×π×6×4 = 48π cm² ≈ 150.72 cm²

Total Surface Area of cylinder = 2×π×6(4 + 6) = 120π cm² ≈ 376.8 cm²

Answer:

Answer:

C.372

Step-by-step explanation:

A prism is a three dimensional shape with two identical shapes facing each other known as bases.

A triangular prism has two triangular bases and three rectangle.

From the net attached:

Area of triangle 1 = area of triangle 2 = (1/2) * base * height = (1/2) * 10 cm * 12  cm = 60 cm²

Area of rectangle 1 = Area of rectangle 2 = length * width = 13 cm * 7 cm = 91 cm²

Area of rectangle 3 = base * height = 10 cm * 7 cm = 70 cm²

Total surface area = Area of triangle 1 + Area of triangle 2 + Area of rectangle 1 + Area of rectangle 2 + Area of rectangle 3

Total surface area = 60 + 60 + 91 + 91 + 70 = 372 cm²
