70% of 200 is 140. 1/4 of 160 is 40. so 70% of 200 is bigger.

Hope this answer helps! feel free to ask any additional questions :)

Also if you are good at Geometry, would you mind seeing if you can answer some of the questions on my profile?

Which expression is equivalent to -7(y-2)

soldi70 [24.7K]

Hello!

Distributive property: a(b+c)=ab+ac

$a=-7, b=y, c=2$

$-7y-(-7)*2$

Minus and plus sign.

$-7y+7*2$

Then multiply by the numbers.

$7*2=14$

$\boxed{=-7y+14}$

Hope this helps!

Thanks!

Have a great day!

Find the value of the expression 4a to the fourth power - 2b squared +40 when a =2 and b=7

Tom [10]

4a^4 -2b^2 +40
a=2
b=7
4(2)^4 -2(7)^2 +40
PEMDAS is what your gonna use to solve this you go from right to left

First is P which is parentheses which is none
second is E which stands for exponents
4(32)-2(49)+40
now MD multiply or divide
128-98+40
now add or subtract
30+40
last one
70 this is your answer i hope

Someone help pls :,)

Answer:

W = 87 degrees

Step-by-step explanation:

First we can rearrange the question so that W is isolated on the left side, which we do by dividing both sides by tan:

tanW/tan = 19.0811/tan

W = 19.0811/tan

Now we can use the inverse tan function on the calculator ( $tan^{-1}$ ) to calculate it:

W = 19.0811 x $tan^{-1}$

W = 87 degrees

Hope this helped!
