% change= (new # - original #) ÷ original # x 100

original #= 98
new #= 62

% change= (62-98)/98 x 100
= -36/98 x 100
= -0.36734 x 100
= -36.73%

Rounded to nearest 10th of %= -36.7%

CHECK:
= 98 - (98 * 36.73%)
= 98 - (98 * 0.3673)
= 98 - 36
= 62 new #

ANSWER:
Her percent error was 36.7% (rounded to the nearest tenth of a percent). The negative indicates a decrease.

Hope this helps! :)

Morgarella [4.7K]
15=7x+1-5x


Put like terms together. ( group anything alike)

15+1=16

7x-5x=2x

16 2x
—- ——-
2x 2x


2x/2x cancels itself out.

16 divided by 2 is 8

x=8

HELPPPPP Find the missing parts of the triangle. Round to the nearest tenth when necessary or to the nearest minute as appropria
Romashka-Z-Leto [24]

The missing parts of the triangle ABC are A = 31.4°, B = 57.4°, C = 91.2°

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more numbers and variables.

Given that a = 8.6 in, b = 13.9 in. and c = 16.5 in. Using cosine rule:

c² = a² + b² - 2abcosC

16.5² = 8.6² + 13.9² - 2(8.6)(13.9) * cosC

C = 91.2°

Also:

a² = b² + c² - 2bccosA

8.6² = 16.5² + 13.9² - 2(16.5)(13.9) * cosA

A = 31.4°

A + B + C = 180° (angles in a triangle)

31.4 + B + 91.2 = 180

B = 57.4°

The missing parts of the triangle ABC are A = 31.4°, B = 57.4°, C = 91.2°

I don't get it can u help me??
andrew-mc [135]

Just look at the percentages and make them into fractions. You can think about it like money. 50 cents is half of a dollar, so %50 is 1/2. for the decimals, you just take the percent and put a decimal point in front of the answer, so 28% is .28, 50% is .50, 18% is .18. For fraction to decimals, you could just put 1 divided by 4 into a calculator and it will tell you .25, which is the decimal, and 25 cents is one fourth of a dollar, so it works out.

Hope this helps! Let me know if you have any more questions!
