Answer:
= 14
Step-by-step explanation:
So my way of doing it is to simply put 20% in decimal so
20= 0.20
Then multiply that by 70
0.20× 70 = 14%
There are probably other ways to do it but I find this way easier

Give Me BrainliestLast term Mark spent $218 on college textbooks. This term the amount he spent on college textbooks decreased by 26.7%. By how much money did his textbook bill decrease this term? What is his total textbook bill for this term?
Answer:
Money decrease = $58.21
Total Bill = $159.79
Step-by-step explanation:
Starting Value = $218
Percent Decrease = 26.7%
End Value = x
Value Decrease = $218 - x
x = 1(218) - 0.267(21.8)
x = 0.733(218)
x = 159.794 ≈ $159.79
Money Decrease = $218 - $159.79 = $58.21
Total Bill = $159.79
-Chetan K
The amount by which the text book decrease is $58.206
The total textbook bill for the term is $ 159.794
How to calculate the total textbook bill for the term?The first step is the calculate the amount by which the textbook decreased
The formular can be written as
Decrease= original amount × percentage decrease
= 218 × 26.7/100
= 218 × 0.267
= 58.206
The amount by which the textbook decreased is $58.206
The total textbook bill for the term can be calculated as follows
= Original amount- amount decrease
= 218 - 58.206

As a nurse, part of your daily duties is to mix medications in the proper proportions for your patients. For one of your regular patients, you always mix Medication A with Medication B in the same proportion. Last week, your patient's doctor indicated that you should mix 50 milligrams of Medication A with 45 milligrams of Medication B. However this week, the doctor said to only use 36 milligrams of Medication B. How many milligrams of Medication A should be mixed this week?
Answer:
40 mg
Step-by-step explanation:
The ratio is 10:9 because 50:45 divided by 5 gives 10:9
if you divide 36/9 that gives you 4, then multiply your ratio by 4 to get 40:36.

Answer:
14.4
Step-by-step explanation:
Because the figures are similar, they are basically the same figure. One is just dilated by a certain amount. To figure out the missing x, we need to find out exactly how much the small one is dilated from the bigger one.
Here's how we do that:
We know 9 and 5 are correlating sides because of where they are in relation to the right angle. We can find out how much smaller 5 is than 9 by dividing 9 by 5.
9 ÷ 5 = 1.8
This means that x is going to be bigger than 8 by a multiple of 1.8.
8 × 1.8 = x
14.4 = x

Answer:
1) 2 and 4
2) 3 and 4
3) 7 and 8
4) 9 and 10
5) 21 and 22
Step-by-step explanation:
#1
Since √(8) = √(2×4) = 2√2
then the √(8) lies between 2 & 3
#2
Since √(9) = 3 & √(16)= 4
then √(14) lies between 3 & 4
#3
√(60) = √(4×15) = 2√(15)
since √16 = 4 and 4 × 2 = 8
then 2√(15) < 8
∴ the √16 lies between 7 & 8
#4
√99 = √(9×11) = 3√11
√11 lies between √9 & √16 but closer to √9
& 3 × √16 = 12
the 3√11 = √99 likely lies between 9 & 10
#5
√444 = √(4×111)= 2√111
since √100 = 10 & √121 = 11
& 2×10= 20 & 2×11= 22
then 2√111 is likely between 21 & 22

Answer:
A) ∠5 = 160°
B) ∠4 = 37°
C) ∠3 = 98°
Step-by-step explanation:
A)
If ∠1 = 160°
⇒ ∠5 = ∠1 = 160° (∵ Corresponding angles are always equal)
B)
If ∠6 = 37°
⇒ ∠4 = ∠6 = 37° (∵ Vertical angles are always equal)
C)
If ∠8 = 82°
⇒ ∠8 = ∠6 = 82° (∵ Alternate interior angles are always equal)
Now ,
∠6 + ∠3 = 180° (∵ Linear pair)
⇒ ∠3 + 82° = 180°
⇒ ∠3 = 180° - 82° = 98°
A production process produces electronic component parts. It is presumed that the probability of a defective part is 0.01. During a test of this presumption, 500 parts are sampled randomly and 15 defectives are observed. (a) What is your response to the presumption that the process is 1% defective
Testing the hypothesis, we have that since the p-value of the test is 0 < 1, our response is that the presumption underestimates the proportion of defective parts.
At the null hypothesis, we test if the proportion of defectives is of at most 1%, that is:
[tex]H_0: p \leq 0.01[/tex]
At the alternative hypothesis, we test if the proportion of defectives is of more than 1%, that is:
[tex]H_1: p > 0.01[/tex]
The test statistic is given by:
[tex]z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}[/tex]
From the sample, we have that:
[tex]n = 500, \overline{p} = \frac{15}{500} = 0.03[/tex]
Thus, the value of the test statistic is:
[tex]z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}[/tex]
[tex]z = \frac{0.03 - 0.01}{\sqrt{\frac{0.01(0.99)}{500}}}[/tex]
[tex]z = 4.49[/tex]
The p-value of the test is the probability of finding a sample proportion above 3%, which is 1 subtracted by the p-value of z = 4.49.
z = 4.49 has a p-value of 1.
1 - 1 = 0.
The p-value of the test is 0 < 1, which means that our response is that the presumption underestimates the proportion of defective parts.

Sum of interior angles in a 4 sided quadrilateral is 360,

180 + 37x - 5 = 360
180 - 5 + 37x = 360

y=x squared - 4x
This is one way of doing it.
We want to get the function into vertex form.
y = x2 - 4x + 2 Subtract 2 from both sides.
y - 2 = x2 - 4x Add (-4/2)2 , or 4, to both sides.
y - 2 + 4 = x2 - 4x + 4 Now that the right hand side is a perfect square trinomial, factor it.
y + 2 = (x - 2)(x - 2)
y + 2 = (x - 2)2 Subtract 2 from both sides.
y = (x - 2)2 - 2
When the equation is in this form, we can see that this is the graph of y = x2 shifted to the right 2 units and shifted down 2 units. The vertex is at (2, -2). So plot the first point at (2, -2) and go up just like a basic parabola from there. :)
