Answer: 14

Step-by-step explanation: The perimeter is all of the side added together. When finding the perimeter of a rectangle the opposing sides have the same value. So the equation would be 2(12) + 2(a) = 52. 12 x 2 is 24. 52- 24 is 28 and youre left with 28 = 2(a). You divide each side by 2 and get 14 = a

Answer:

On a coordinate plane, a line has a negative slope

Step-by-step explanation:

If a graph only shows one line, there is an infinite amount of solutions. We need two separate line equations to cross at a point in order to find the solution to the system. However, if a graph shows two parallel lines that never cross, there are no solutions to that systems of equations.

Answer:

The correct answer is the last graph (C).

Answer:

1/4 mile

Step-by-step explanation:

A = length · width

let 'n' = length

1/8 = 1/2n

8n = 2

n = 2/8 or 1/4

Answer: B.1 2/5 − a fraction less than 2/5

Step-by-step explanation:

Question was not formatted properly and in the proper format, the above is the answer.

1²/₅ - ²/₅ = 1

Any number therefore that is lower than ²/₅ will when subtracted from 1²/₅ give an answer greater than 1 because when ²/₅  was subtracted from  1²/₅, it gave 1 as an answer.

Answer:

49m^4 - 25

Step-by-step explanation:

The simpler expression can simply be found by expanding

The kind of expansion we have here is the difference of two squares

(a + b)(a-b) = a^2 - b^2

Thus, we have it that;

(7m^2-5)(7m^2 + 5)

=

49m^4 - 25

Answer: $259.20

Step-by-step explanation: Divide $32.40 by 3 to get $10.80. Then multiply $10.80 by 24 (2 years).

Answer:

$259.20

Step-by-step explanation:

32.4·4=129.6

129.6·2=259.2

Additional info

Twelves months in one year so 12÷3=4

Two years so 129.6·2

Just in case you were wondering how I got 4 and 2

Step-by-step explanation:

.45x25+10.00= 21.25

.65x25+5.00=21.25

Yes, the reaction is balanced.

Among the reactants, we have

• 8 carbon

• 20 hydrogen

• 26 oxygen

and among the products,

• 8 carbon

• 16 + 10 = 26 oxygen

• 20 hydrogen

Answer:

Simple Answer... Yes it is balanced.

Answer: =3.5x Slope:

3.5

y-intercept:

0

Step-by-step explanation:

y=-3.5x-10 is an inverse proportional.

Given that, the given equation is y= -3.5x-10.

Proportional relationships are relationships between two variables where their ratios are equivalent. Another way to think about them is that, in a proportional relationship, one variable is always a constant value times the other. That constant is known as the "constant of proportionality".

Put x=0, 1, 2, 3, and 4 in the given equation.

When x=0

y=-10

When x=1

y=-3.5(1)-10

=-3.5-10

=-13.5

When x=2

y=-3.5(2)-10

=-7-10

=-17

When x=3

y=-3.5(3)-10

=-10.5-10

=-20.5

Here, x increases and y decreases, it is inverse proportionality

Therefore, y=-3.5x-10 is an inverse proportional.

Step-by-step explanation:

Answer:

24 DVDs

Step-by-step explanation:

45% of 160 = 72

40% of 160 = 64

72+64=136

160-136=24

Answer:

9°

Explanation:

So, since the arrow is pointing to a RIGHT angle, you have to know the right angle's degree is 90° so set up an equation.

11x - 9 = 90

Now you solve it. Here's a step by step:

11x - 9 = 90

Add nine to nine and ninety. Since the nine in this equation is negative, it'll cancel it out. Now here's what you have left to solve:

11x = 99

Divide -11 from 11 and 99.

x = 9

If you feel like you're wrong, fill it in!

11(9) - 9 = 90

11 x 9 = 99

99 - 9 = 90

There you go!

Answer:

The sum of x and seven, or x plus seven, or the product of x and seven.

41.803 is 42 rounded to the nearest whole number because when you go past .5 you round to the nearest highest number, but when your below .5 then you round to the nearest lowest number.

Answer: 41.803 rounded to the nearest whole number would be 42. Whenever you go over .5 you round to the nearest highest number. For example, 41.6 would also be rounded to 42.

Answer:

[tex]c=14[/tex]

Step-by-step explanation:

a = 18.2

[tex]\angle B=62^{\circ}[/tex]

[tex]\angle C=48^{\circ}[/tex]

[tex]\angle A=180-(62+48)=70^{\circ}[/tex]

From sine rule we have

[tex]\dfrac{\sin A}{a}=\dfrac{\sin B}{b}=\dfrac{\sin C}{c}[/tex]

[tex]\Rightarrow \dfrac{\sin A}{a}=\dfrac{\sin C}{c}[/tex]

[tex]\Rightarrow c=\dfrac{\sin C}{\sin A}a[/tex]

[tex]\Rightarrow c=\dfrac{\sin 48^{\circ}}{\sin 70^{\circ}}\times 18.2[/tex]

[tex]\Rightarrow c=14.4\approx 14[/tex]

[tex]\boldsymbol{\therefore c=14}[/tex].
