A small toy car costs $3. A large toy car costs 5 times as much as the small one.
Aaron wants to buy one of each. Which equation can he use to find the cost (a)
of the two cars?

Answer:

answer is D

Step-by-step explanation:

as we need to cancel the square in b

so we add square root on both sides and square root of 2.56 is 1.6

Answer:

C and D

Step-by-step explanation:

Given

b² = 2.56 ( take the square root of both sides )

b = ± [tex]\sqrt{2.56}[/tex] = ± 1.6

Then solutions are

b = - 1.6 → C

b = 1.6 → D

Answer:

The area of the base and the height of the object

Step-by-step explanation:

you need to know these so you can us the formula      B x H = V

B = base

H = height

V = volume

Answer:

what's the context of this?

Answer:

B

Step-by-step explanation:

5t^2-(3-6t-8t^2)

=5t^2-3+6t+8t^2

=13t2-3+6t

Answer:

[tex]\boxed {\boxed {\sf B. \ 13t^{2} -3+6t}}[/tex]

Step-by-step explanation:

We are given this expression and asked to simplify:

[tex]5t^2-(3-6t-8t^2)[/tex]

First, distribute the -1. Multiply each term in the parentheses by -1 or switch the sign of every term inside the parentheses.

[tex]5t^2+ (-1*3)+(-1*-6t)+(-1*-8t^2)[/tex]

[tex]5t^2+(-3)+(6t)+(8t^2)[/tex]

[tex]5t^2-3+6t+8t^2[/tex]

Next, combine like terms. We see that two terms have a t², so they are like terms. We can add them together.

[tex](5t^2+8t^2)-3+6t[/tex]

[tex]13t^2-3+6t[/tex]

The simplified expression is 13t²-3+6t and Choice B is correct.

Answer:

a) -1535.5

b) 0

Step-by-step explanation:

A) We do this problem according to its parenthesis. First, let's evaluate the first half, -2[(-1/4)-12(-1)^2]. We have to do (-1)^2 first, because of PEMDAS. (-1)^2 is just 1. Now, our equation is -2[(-1/4)-12*1]. Thus, we get -2[(-1/4)-12] because 12*1 is just 12. Then, we do (-1/4)-12, giving us -12.25. Our equation becomes -2(-12.25). Then, we just get 24.5.

The next half, -5[24+2(-12)^2] is similar. We first evaulate (-12)^2 because of PEMDAS, giving us 144. Then, we have -5[24+2(144)]. 2 times 144 is 288, so we get -5[24+288]. 24 + 288 is 312, so we have -5(312). This finally gives us -1560.

Putting the two together, we get 24.5 - 1560, which is -1535.5.

--------------------------------------------------------------------------------------------------------------B) We substitute a = -1/3 and b = -1 into the equation, -a^2b^2 - 3a^3b^2.

We plug in -1/3 where a is and -1 where b is. So:

-(-1/3)^2(-1)^2 - 3(-1/3)^3(-1)^2.

The tricky part of this problem is making sure you follow PEMDAS. We evaluate the exponents first.

-1/9 * 1  - 3(-1/27) * 1

= -1/9 + 1/9

= 0

Answer:

10 units ^2

Step-by-step explanation:

Area 1:

A = lw

   = 2 * 5 = 10

Answer:

12.32 units

Step-by-step explanation:

Use the distance formula to find the lengths between two points:

[tex]d=\sqrt{(x_{2} -x_{1})^2+(y_{2}-y_{1})^2 }[/tex]

the distance between (-2, -1) and (-5,-1) is

[tex]\sqrt{(-2-(-5))^2+(-1-(-1))^2}[/tex]

=[tex]\sqrt{3^2+0^2}[/tex]

=[tex]\sqrt{9}[/tex]

=3

the distance between (-2, -1) and (-3, -4) is

[tex]\sqrt{(-2-(-3))^2+(-1-(-4))^2}[/tex]

=[tex]\sqrt{1^2+3^2}[/tex]

=[tex]\sqrt{10}[/tex]

≈3.16

the distance between (-6, -4) and (-3, -4) is

[tex]\sqrt{(-6-(-3))^2+(-4-(-4))^2}[/tex]

=[tex]\sqrt{(-3)^2+0^2}[/tex]

=[tex]\sqrt{9}[/tex]

=3

the distance between (-6, -4) and (-5, -1) is

[tex]\sqrt{(-6-(-5))^2+(-4-(-1)^2}[/tex]

=[tex]\sqrt{(-1)^2+3^2}[/tex]

=[tex]\sqrt{10}[/tex]

≈3.16

Now, add all the sides:

3+3.16+3+3.16=12.32 units

Note: A property of a parallelogram is that it has two pairs of congruent sides, so for this problem, you could solve for 2 different sides, double them, then add and you will get the same thing.

Answer:

41x² - 27x + 27

Step-by-step explanation:

Perimeter of Rectangle:

= 2(20x²-12x+4) + 2(5x²-5x+15)

= 40x²-24x+8 + 10x²-10x+30

= 50x²-34x+38

Perimeter of Triangle:

= 6x²+6x+3x+3+3x²-2x+8

= 9x²+7x+11

Difference:

(50x²-9x²)+(-34x+7x)+(38-11)

= 41x² - 27x + 27

Step-by-step explanation:

Here is your answer :

Answer 1 :

Volume of the Cylinder = πr²h

Therefore, The Volume of the Cylinder is 50.27 Feet

By Rounding, 50 Units/Feet

Answer 2 :

So, volume is always cubed since you have l x w x h.

A cubic ft is 12 in x 12 in x 12 in = 1728 in3.

35328.78/1728 = 20.44  

20.44 x 7.48 = 152.89
