games unlimited buys video games for $10. The store increases the price 300%. What is the price of the video game?

1 answer:

5 0

To solve this problem, identify the starting payment for video games that is given in the question. This is $10.

Since the company decides to increase the price by 300%, you have to multiply to get the new price.
Start by finding 100% on $10.
Since 100% of $10 is all that is there, that is another $10.

So now that you know a baseline for the increase in price, multiply that base by three to find the increase in price.
10 x 3 = 30

So, the company adds $30 to the price.
A simple addition problem gives you the new final price:
10 + 30 = 40

So, video games are now bought for $40 rather than $10.

I hope this helps! :)

In the diagram mz3= x+ 30 and mz4 =2x-80. What is the measure of angle 3?

Andreas93 [3]

Given:

Consider the below figure attached with this question.

$m\angle 3=(x+30)^\circ$ and $m\angle 4=(2x-80)^\circ$ .

To find:

The measure of angle 3.

Solution:

From the below figure it is clear that, angle 3 and angle 4 are vertically opposite angles.

We know that, vertically opposite angles are always equal. So,

$m\angle 3=m\angle 4$

$(x+30)^\circ=(2x-80)^\circ$

$x+30=2x-80$

$x-2x=-30-80$

$-x=-110$

$x=110$

Now,

$m\angle 3=(110+30)^\circ$

$m\angle 3=140^\circ$

Therefore, the measure of angle 3 is 140 degrees.

A triangular lot has sides of 215m, 185m, and 125m. Find the measures of the angles at its corners

Vlada [557]

Answer:

The measures of the angles at its corners are $59.1\°,35.4\°,85.5\°$

Step-by-step explanation:

see the attached figure to better understand the problem

step 1

Find the measure of angle A

Applying the law of cosines

$185^{2}= 215^{2}+125^{2}-2(215)(125)cos(A)$

$2(215)(125)cos(A)= 215^{2}+125^{2}-185^{2}$

$cos(A)= [215^{2}+125^{2}-185^{2}]/(2(215)(125))$ $cos(A)=0.513953$

$A=arccos(0.513953)=59.1\°$

step 2

Find the measure of angle B

Applying the law of cosines

$125^{2}= 215^{2}+185^{2}-2(215)(185)cos(B)$

$2(215)(185)cos(B)= 215^{2}+185^{2}-125^{2}$

$cos(B)= [215^{2}+185^{2}-125^{2}]/(2(215)(185))$ $cos(B)=0.81489$

$B=arccos(0.81489)=35.4\°$

step 3

Find the measure of angle C

Applying the law of cosines

$215^{2}= 125^{2}+185^{2}-2(125)(185)cos(C)$

$2(125)(185)cos(C)= 125^{2}+185^{2}-215^{2}$

$cos(C)= [125^{2}+185^{2}-215^{2}]/(2(125)(185))$ $cos(C)=0.0784$

$C=arccos(0.0784)=85.5\°$

Emily has a babysitting job that pays $11 per hour. She wants to know how many hours she has to babysit to afford a

SCORPION-xisa [38]

Answer: 165=11h

Step-by-step explanation:

I believe it would be 165=11h because you have to multiply the number of hours she worked times 11 to get the amount that would equal 165!

Solve 2(x + 1) = 2x + 2.<br> A All real numbers<br> B No solution<br> C 0<br> D 1

FrozenT [24]

2(x+1)=2x+2 if you factor the right side ..

2(x+1)=2(x+1)

This is always true for any value of x so there are infinitely many solutions...

x= all real numbers.
