Answer:
133.2
Step-by-step explanation:
First take off the 40%
740 - (40/100)*740
740 - 0.4 * 740
740 - 296
444
=========================
That answer of 444 is the new selling price.
Now you take 30% of 444
30% of 444
30/100 * 444
0.3 * 444
133.2
Joseph will have to pay 133.2 dollars for the TV he want.
===========================
One Step
===========================
You could do this problem all in one step
30% (740*60% )
0.3 ( 740*0.6)
0.3(444)
133.2
=================
Both methods give the same answer.
Answer:
x= 30
The angles measure 80 degrees
Step-by-step explanation:
The two angles are corresponding angles and, when the lines are parallel, corresponding angles are equal.
2x+20 = 3x-10
Subtract 2x from each side
2x+20-2x = 3x-10-2x
20 = x-10
Add 10 from each side
20+10=x-10+10
30 = x
2x+20 = 2(30) +20 = 60+20 = 80
Answer:
317.21 (sales price)
259.53 (discount amount)
Step-by-step explanation:
First, we need to divide.
576.75/100=5.7675 (note that I will be rounding at the end)
5.7675 x 55 (100-45) = 317.2125
Rounds to: 317.2<u>1</u>
<u></u>
Now, we need to find the discount amount.
576.75
-317.21
=259.53
1. The data is not linear. There's not a constant difference between the f(x) values. (AKA there's not a fixed slope between the data points)
2. The data is exponential, because there's a consistent ratio in the f(x) values:
189/567 = 1/3
63/189 = 1/3
21/63 = 1/3
7/21 = 1/3
Each new y-value (aka f(x)-value) is 1/3 the previous value.
Also, f(0)=567.
If we put that together, we have f(x) = 567 (1/3)^x.
Answer:
About 41.5%
Step-by-step explanation:
<em>Given:</em>
<em>A bowl has 8 green grapes and 15 red grapes. Henry randomly chooses a grape, eats it, and then chooses another grape. </em>
<em>To Find:</em>
<em>What is the probability that both grapes are red?</em>
<em>Answer choices:</em>
<em>about 39.7% </em>
<em>about 41.5%</em>
<em> about 42.5% </em>
<em>about 44.5%</em>
<em>Solution:</em>
<em>Since, there are 8 green grapes and 15 red grapes, the total number of grapes is 23 . </em>
<em>As the red grapes are 15.. </em>
<em>Thus, </em>
<em>The probability of choosing a red grape the first time is 15/23.</em>
<em>Because out of the total 23 grapes only 15 were red grape.</em>
<em> The probability of choosing the red grape the second time will be 14/22. Because the number of red grapes has already decreased by one and so is the total number of grapes after first choice</em>
<em>Hence, the probability of choosing or eating two red grapes will be :</em>
<em>15/23×14/22 </em>
<em>=105/253 </em>
<em>=0.415</em>
<em>= 41.5% </em>
<em>Therefore, the probability that both grapes are red is about 41.5%</em>
