Find the value of X.
Answer:
X = 5
Step-by-step explanation:
Angles on a straight line=180°
180-151=29°
sum of angles in a triangle= 180°
11x-1+20-3+29=180
11x+20x-3-1+29=180
31x+25=180
31x=180-25
31x=155
divide both sides by 31
X=5
(11x-1)°= 55-1= 54°
(20x-3)°= 100-3= 97°
54°+97°+29°=180°

The equivalent multiplication equation is 1/2 x 1/4.
What is Fraction?The fractional bar is a horizontal bar that divides the numerator and denominator of every fraction into these two halves.
The number of parts into which the whole has been divided is shown by the denominator. It is positioned in the fraction's lower portion, below the fractional bar.How many sections of the fraction are displayed or chosen is shown in the numerator. It is positioned above the fractional bar in the upper portion of the fraction.Given:
1/2 ÷ 4
As, the fraction does not support division.
So, to perform the division we change the division sign into multiplication sign and reciprocate the number on the right side of division sign.
Then, 1/2 ÷ 4
= 1/2 x 1/4
= 1/8
Hence, the equivalent multiplication equation is 1/2 x 1/4.

For males in a certain town, the systolic blood pressure is normally distributed with a
mean of 110 and a standard deviation of 9. Using the empirical rule, determine the
interval of systolic blood pressures that represent the middle 95 of males.
Answer: (92, 128)
Step-by-step explanation:
According to the Empirical rule,
If the population is normallly distributed, then 95% of the population lies within 2 standard deviations from the mean.
Given: Mean = 110
Standard deviation = 9
The interval of systolic blood pressures represent the middle 95% of males:
(110-2(9), 110+2(9))
= (110-18, 110+18)
= (92, 128)
Hence, the interval of systolic blood pressures that represent the middle 95 % of males = (92, 128)
Answer:
its 92, 128

A jar contains n nickels and d dimes. There are 17 coins in the jar, and the total value of the coins is $1.10. How many nickels and how many dimes are in the jar? (Hint: Nickels are worth $0.05 and dimes are worth $0.10.)
Answer:
Here's what we know:
n + d = 20 (there are a total of 20 nickels and dimes)
.05n + .1d = 1.4 (total change equals $1.40)
There are a couple of ways to solve this. You can go the elimination method by multiplying the second equation by an amount to get rid of a variable, or we can go substitution by isolating a variable in the first equation. I'll go with elimination in this case:
-10(.05n + .1d = 1.4) this will cause the d-variable to equal 0:
n + d = 20
-.5n - d = -14
------------------
.5n = 6
n = 12
Now that we know n, we can solve for d:
12 + d = 20
d = 8
Check:
.05 * 12 + .1 + 8 = 1.4
.6 + .8 = 1.4
1.4 = 1.4

HI there!
This is a compound interest question, so we will use the formula
[tex]x = p(1+\frac{r}{n})^n^t[/tex]
P being our principle amount, $15,000 in this case,
R being our rate, or 1.25
N being our compound rate, which is semiannually, or twice a year.
T is our time, being 3.
After plugging these values in, we get

The gas tank in your vehicle holds 12 gallons of gas. If you get 30 miles per gallon, how many miles can you drive on a full tank?
Answer:
you can get 360 miles on a full tank
Step-by-step explanation:
Answer:
Every 1 Gallon will get you 30 Miles
So, if you have 12 Gallons then you can travel 360 Miles
You just multiply the amount of miles you can travel per gallon by the total amount of gallons that can be held by the gas tank. This will get you the max miles you can drive before running completely out of gas.
