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

1.A different of two square has a middle term.
2.The binomial x² + 4 is equal to (x + 2) (x + 2).
3. The complete factored form of x⁴ - 16 is (x² + 4) (x² - 4)
4. When x + 3 is multiplied by x - 3, the product is a perfect square trinomial.
1. True.
2. False. x² + 4 = (x+2)(x-2)
3. True.
4. False. It gives (x²-9) which is a binomial.

Answer:

Step-by-step explanation:
Sum of interior angles in a 4 sided quadrilateral is 360,
110 + 70 + 14x + 23x - 5 = 360
180 + 37x - 5 = 360
180 - 5 + 37x = 360
175 + 37x = 360
37x = 360 - 175
37x = 185
x = 185 / 37
x = 5
Step-by-step explanation:
We know that,
For a tetragon the sum of all 4 angle is 360°
According to the question,
70+110+(23x-5)+14x=360180+23x-5+14x=36037x-5=360-18037x=180+537x=185x=[tex]\sf{\dfrac{185}{37} }[/tex]x=5what is 7.2 times 10 with the exponent of 5

Transpose for y.
y/5+ f = 3q
Answer:
y = 15q - 5f
Step-by-step explanation:
[tex]\frac{y}{5}[/tex] + f = 3q ( subtract f from both sides )
[tex]\frac{y}{5}[/tex] = 3q - f ( multiply through by 5 to clear the fraction )
y = 15q - 5f
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.
27/125 in simplest form
[tex] \frac{27}{125} [/tex]
It is already in the simplest form. It can be written as 0.216 in decimal form (rounded to 6 decimal places).
Answer:
27 /125
is already in the simplest form. It can be written as 0.216 in decimal form (rounded to 6 decimal places).
Step-by-step explanation:
Find the GCD (or HCF) of numerator and denominator
GCD of 27 and 125 is 1
Divide both the numerator and denominator by the GCD
27 ÷ 1 /125 ÷ 1
Reduced fraction:
27 /125
Therefore, 27/125 simplified to lowest terms is 27/125.

Step-by-step explanation:
20 ÷ 4 1/2
let's change 4 1/2 into an improper fraction.
20 ÷ 9/2
20 is the same thing as 20/1, so we'll express it that way.
[tex]\frac{20}{1}[/tex] ÷ [tex]\frac{9}{2}[/tex]
in order to divide fractions, you must multiply the first number (20/1) by the inverse of the second number (2/9). I'll put it in normal fraction form for clarity.

Last 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
= 159.794
The total textbook bill for the term is $159.794

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:
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

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.

B. If the measure of 6 =37°, then the measure of 4 =
C. If the measure of 8 = 82, then the measure of 3 =
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°

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. :)
