Answer: 55% decrease

Step-by-step explanation:

% decrease is calculated by = [ (New Value - Old Value) / Old Value × 100

63 - 140 = -77

-77/140 = -0.55

- 0.55 x 100

= -55%

Answer:

55% decrease

Step-by-step explanation:

To find the percent decrease

Take the original price and subtract the new price

140-63 =77

Divide by the original price

77/140

.55

Multiply by 100 to get the percent

.55*100 = 55%

55% decrease since the price got lower

The given expression $8(4)^2+2^4$ is equal to 144 or $12^2$

<em><u>Solution:</u></em>

Given expression is:

$8(4)^2+2^4$

We have to evaluate the above given expression

We know that,

$(4)^2 = 4 \times 4 = 16$

$2^4 = 2 \times 2 \times 2 \times 2=16$

Substituting these in above given expression, we get

$8(4)^2+2^4=8 \times 16+16\\\\8(4)^2+2^4= 128+16\\\\8(4)^2+2^4=144$

Also we know that,

$12 \times 12 = 144$

Therefore,

$8(4)^2+2^4=144 = 12 \times 12 = 12^2$

Thus the given expression $8(4)^2+2^4$ is equal to 144 or $12^2$

x = 5

y = -1

Step-by-step explanation:

from second equation,

y = -2 + 1
y = -1

by putting the value of y in first equation

y = -x + 4
-1 = -x + 4
-x = -1 -4
-x = -5
x = 5

x = 5 and y = -1

According to the diagram, how far is point L from Rays KH and HF?Find the value of Y

RideAnS [48]

Answer:

The distance between L and the line KH and HF is;

$27$

The value of y is;

$y=9$

Explanation:

Given the figure in the attached image;

$\begin{gathered} KL=27 \\ KHL=(6y)^{\circ} \\ FHL=(4y+18)^{\circ} \end{gathered}$

From the image;

$KL=FL=27$

So, the distance between L and the line KH and HF is;

$27$

Also, the triangles KHL and FHL are congruent.

So, the angles KHL and FHL are congruent.

$m\measuredangle KHL\cong m\measuredangle FHL$

Substituting the expressions;

$\begin{gathered} (6y)^{\circ}=(4y+18)^{\circ} \\ 6y=4y+18 \\ 6y-4y=18 \\ 2y=18 \\ y=\frac{18}{2} \\ y=9 \end{gathered}$

Therefore, the value of y is;

$y=9$
