Answer:

90

Step-by-step explanation:

Step 1: Given data

Side of the rectangular prism (s): 3

Height of the rectangular prism (h): 6

Step 2: Calculate the surface area (SA) of the base

We will use the following expression, replacing the values for s and h.

SA = 2 × s² + 4 × s × h

SA = 2 × 3² + 4 × 3 × 6 = 90

The units are not provided but the SA should have the same units as s and h, but raised to the power of 2.

Solve the following system of equations. <br> y = 12 - 5x <br> 2x + 3y = 11
Sindrei [870]
Use substitution
2x + 3(12 - 5x) = 11
Distributive property
2x + 36 - 15x = 11
Combine like terms
-13x + 36 = 11
Subtract 36
-13x = -25
x = 25/13
y = 12 - 5(25/13)
y = 31/13
Solution: x = 25/13, y = 31/13

if an amount of $100 in a savings account increases by 10% , then increases by 10% again, is that the same as increasing by 20%
Elina [12.6K]


100 + 100 * 10/100 = 110

NOW 110 INCREASES BY 10 %, 110 + 110*10/100 = 110+ 11 = 121

INCREASE OF 20 % = 100 + 100*20/100= 100+20 = 120

SO IT IS NOT SAME

Do you know has three times as many dimes as quarters the dollar amount of her dimes and quarters is $6.05 how many quarters doe
vesna_86 [32]

The number of quarters she have 11.

<h3>What is a system of equations?</h3>

A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.

Let consider y = quarters; x = dimes

We know that there are 3 times as many dimes as quarters. So we can state that x = 3y.

Then, we say that 25y + 10x = 605

(Value of coin * amount of coins)

Then we substitute x=3y into the equation, yielding:

25y + 10(3y) = 605

25y + 30y = 605

55y = 605

605/55 = 11 = y

Therefore, the number of quarters she have 11.

Which represents the polynomial below written in standard form?
STALIN [3.7K]

Answer:

B. 4x^3}+\frac{x^2}{2}-3x+6

Step-by-step explanation:

The polynomial is \frac{x^2}{2}-3x+4x^3}+6

To write in Standard form, the greatest exponent goes first, down to the least.

The greatest exponent is 3, so 4x^3 goes first.

4x^3}+\frac{x^2}{2}-3x+6 is what you end up with
