Solve for x.
A) 13
B) 26
C) 11
Answer:
13
Step-by-step explanation:
Once again we are looking at inscribed angles and intercepted arcs. Like stated previously an inscribed angle is equal to half its intercepted arc
That being said we want to create an equation to solve for x
The equation would be 7x + 5 = 192/2
We now solve for x
step 1 simplify
192/2=96
now we have 7x + 5 = 96
step 2 subtract 5 from each side
5 - 5 cancels out
96 - 5 = 91
7x = 91
step 3 divide each side by 7
7x/7 = x
91 / 7 = 13
we're left with x = 13
NEED HELP ASAP 15 POINTS
Answer:
mean = 2
median = 2.5
Step-by-step explanation:
There are a total of 20 goals (1*0 + 3*1 + 1*2 + 3*5 = 0 + 3 + 2 + 15 = 20)
There are 10 games, so 20/10 = 2 = mean
Threre are 5 games with goals greater than 2.5 and 5 games with goals below 2.5. So the median is 2.5

A square has an area of 16 square ft what would be the measurement of its side
Answer:
4ft
Step-by-step explanation:
to get the area of a square you multiply the sides together so you just find the square root of the area
Answer:
4 feet would be the legth of the squares side
Step-by-step explanation:
t16 is the squares area and the area of a square is length X width, since all the sides of a square are equal, we can just take the square root of 16 which is 4 feet.
A laptop computer is purchased for $2000. After each year, the resale value decreases by 25%. What will the resale value be after years?
Use the calculator provided and round your answer to the nearest dollar.
$[]
Answer:
2000? ... assume $2000
Resale Value = $2000*(1 - 0.25)t/yr
where: t = number of year after purchase
at t = 3 yr
Resale Value = $2000*(1 - 0.25)3 = $843.75
checking: at t = 0 $2000 (purchase price)
at t = 1 yr $2000 - 0.25*$2000 = $2000 - $500 = $1500
at t = 2 yr $1500 - 0.25*$1500 = $1500 - $375 = $1125
at t = 3 yr $1125 - 0.25*$1125 = $1125 - $281.25 = $843.75

Work out the size of angle x.
105
140
Answer:
Step-by-step explanation:
Sum of angles of a triangle = 180
x + (180 - 105) + (180 -140) = 180
x + 75 + 40 = 180
x = 180 -75 - 40
x = 65

A principal of $3000 was
invested in a savings account
for 3 years. If the interest
earned for the period was
$450, what was the interest
rate?
A=P+Prt
Answer:
r = 0.05 or 5%
Step-by-step explanation:
3450 = 3000 + (3000 · r · 3)
450 = 9000 · r
450/9000 = r
r = 0.05 or 5%

Classify the object with the given side lengths as acute, obtuse, right, or not a triangle.
16, 21, 28
Right
Acute
Obtuse
Not a triangle
Answer:
We have to first see that the given lengths makes a triangle or not by using a+b > c in which a,b and c are
length of sides of a triangle lets check out
16 + 21 = 37 > 28
21 + 28 = 49 > 16
16+ 28 = 44 > 21
As because the statement fits correct in the lengths given so its a triangle
So we can say that the triangle is scalene by means of measurements
but cant be a right angle as by taking the pythagorean triplet
= a^2 + b ^ 2 = c^2
lets see if a=16, b = 21 and c = 28
So a^2 + b^2
= 256 + 441
= 697
but c^2
= 28^2 = 784
As 441 =/= 784
So The triangle lengths cant be a right angled triangle
So 1/2 of possibility is the traingle acute and 1/2 of the possibilty that the triangle is obtuse
Now you can find the correct triangle on the basis of acute or obtuse angle by drawing with given length of sides of triangle
Hope it helps

what is the HCF of 3000 and 525 answer with process
Answer:
The HCF is 75
Step-by-step explanation:
Here, we want to get the highest common factors of the two numbers
To do this, we have to write the numbers as the product of their prime factors
We have;
3,000 = 2 * 2 * 2 * 3 * 5 * 5 * 5
525 = 3 * 5 * 5 * 7
now looking at this, we can see that in both numbers, we can have 3 * 5 * 5 taken out as it is common to both numbers
This represents the highest common factor of the two numbers
and that is 75

Deena drinks 2 cups of milk per day. She buys 5 quarts of milk. How many days will her 5 quarts of milk last?
Answer:
10 days
Step-by-step explanation:
Given data
Deena drinks 2 cups of milk per day
from table
1 cup = 0.25 quarts
Hence she drinks
0.5quarts per day
Hence if 0.5quarts last for 1 day
5quarts will last x days
cross multiply
0.5x= 5*1
x= 5/0.5
x=10 days

Answer:
∠A = 126°
Step-by-step explanation:
Supplementary angles are angles that add up to equal 180°
Given that ∠B = 54°, we can subtract 54° from 180°.
180° - 54° = 126°
∠A = 126°

The mean age of 11 women in an office is 31 years old.
The mean age of 6 men in an office is 29 years old.
What is the mean age (nearest year) of all the people in the office?
Answer: 30.2
Explanation:
The mean is calculated by taking the sum of the values and dividing by the count.
For instance, for the 6 women, with the mean being 31, we can see that the ages summed to 186:
186
6
=
31
And we can do the same for the men:
116
4
=
29
And now we can combine the sum and count of the men and women to find the mean for the office:
186
+
116
10
=
302
10
=
30.2
Step-by-step explanation:
9514 1404 393
Answer:
30
Step-by-step explanation:
The total of the ages of the 11 women is 11·31 = 341. The total of the ages of the 6 men is 6·29 = 174. Then the total of the ages of all 17 people in the office is ...
341 + 174 = 515
and their average age is ...
515/17 ≈ 30.294 ≈ 30
The mean age of the people in the office, to the nearest year, is 30.
_____
The mean is the total divided by the number of contributors. Then the total is the mean times the number of contributors.
Based on historical data, your manager believes that 43% of the company's orders come from first-time customers. A random sample of 243 orders will be used to estimate the proportion of first-time-customers. What is the probability that the sample proportion is between 0.2 and 0.39?
Answer:
Following are the solution to the question:
Step-by-step explanation:
[tex]p = 0.43\\\\n = 243\\\\\sigma =\sqrt{\frac{p(1-p)}{n}}=\sqrt{\frac{0.43 (1 -0.43)}{243}}=0.0013[/tex]
z-score for [tex]\hat{p}=0.2[/tex] will be:
z score for will be:
[tex]z=\frac{\hat{p}-p}{\sigma}=\frac{0.39 - 0.43}{0.0013}=-30.76[/tex]
[tex]P(0.2 <\hat{p}< 0.39) = P(-176.92 < z < -30.76)[/tex] using excel method to calculate the value.

If you graph the equation you can see that it doesn't cross the x-axis. It doesn't go lower than y=1. If you don't have a graphing calculator use Desmos. Also the +1 at the end of the equation tells you that it won't go lower than y=1.
Answer:
Never your answer is 0
Step-by-step explanation:
The equation creates what's called a parabola the line curves up the 1 represents the y axis so the line curves up from the y axis point 1 never touching the x axis
