Answer:
Hello! answer: 16
Step-by-step explanation:
These are a bit different instead your solving for B so you have to work backwords so... 20 × 20 = 400 12 × 12 = 144 400 - 144 = 256 now we just find out what multiplied by itself = 256 16 × 16 = 256 therefore b = 16 Hope that helps!

GD : GC = 1 : 2 = 7 : 14 . . . . . . . . multiply the ratio by 7
GC = 14
What's the answer for this?
Answer:
50
Step-by-step explanation:
if 50 degrees is the angle across from b, then 50 is b. 50 applies to b as well. whatever is across from it is the same thing. all of the angles should add up to 360 at an intersection.
If I earn $21.30 an hour and work 12 hours how much money will I have in 2 days?
According to the question,
Earnings I get for working an hour = $21.30Total hours I work in a day = 12 hoursWe are asked to calculate how much money will I have in 2 days.
If in one day, I work 12 hours, so
→ Total hours I'll work in 2 days = 2(12) hours
→ Total hours I'll work in 2 days = 24 hours
Also, in the question it is given that,
→ Earnings I get for working an hour = $21.30
→ Earnings I'll get for working 24 hours = $(21.30 × 24)
→ Earnings I'll get for working 24 hours = $511.2
Therefore, I'll have $511.2 in two days.
Answer:
Earning per hour = $21.30
No. of hours he works = 12 hours
So in two days no. of hours he work = (12×2) hours = 24 hours
He earned in two days = 24 × $21.30 = $ 511.20 ( ans)
Hope it helps

Bro this is so simple but I don't know. At the party, jorden shared out all the loonies in his present. Altogether there was 47 Lolies and 6 boys. How many lollies were leftover.
Answer:
5 lollies are left over
Step-by-step explanation:
Total lollies Jordan has = 47
Number of boys at the party = 6
If the lollies are shared equally,
Number of lollies each boy gets = Total lollies ÷ number of boys
= 47 ÷ 6
= 7 lollies remainder 5
That is,
6 boys × 7 lollies each = 42 lollies
How many lollies were leftover.
Remaining lolly = Total lollies - shared lollies
= 47 - 42
= 5 lollies are left over

Answer:
the length of the road after 25 days:L = 41 + 25

a wise man once said "500 reduced by 4 times my age is 200." what is his age?
Answer: Well, when the wise man said "500 reduced by 4 times my age is 200." A wise women came up to him and responded " Your age is 75"
Step-by-step explanation:
If 500 reduced by 4 times your age is 200, then the equation
500 − 4x = 200
Take away 200 from both sides of the equation.
Add 4x to both sides of the equation.
Divide both sides of the equation by 4, you get 75 = x.
So, if 500 reduced by 4 times your age is 200, then you are 75.
Answer:
Step-by-step explanation:
let the age of old man be x
given word problem in equation form=
500-4x=200

Find the mean number of hours for these students.
If necessary, round your answer to the nearest tenth.
Answer:
10.9
Step-by-step explanation:
The "mean" is just school's fancy way of saying "the average". To find the mean of the numbers, you add them all up first. 12 + 5 + 14 + 6 + 17 + 7 + 15 = 76. The next step is to divide 76 by the number of values that were added. 12, 5, 14, 6, 17, 7, and 15 are a total of 7 numbers. So, we will divide 76 by 7.
76/7 = 10.8571428571, which rounds to 10.9 if you are rounding it to the nearest tenth.
Answer:
[tex]\boxed {\boxed {\sf 10.9 \ hours }}[/tex]
Step-by-step explanation:
The mean is also called the average. It is a measure of central tendency and provides information about the center of a data set.
The mean is found by adding up all the values, then dividing by the number of values. Remember, this is the data set we have:
12, 5, 14, 6, 17, 7, 15
1. Add up values
12 + 5+ 14 + 6 + 17 + 7 + 15= 76
2. Divide by the number of values
There are 7 values ( 1 for each student)76/7=10.8571428571
3. Round
We need to round our answer to the nearest tenth. The 5 in the hundredth place tells us to round the 8 up to a 9.10.8571428571 ≈ 10.9
The mean number of hours spent watching television for this group of students is 10.9 hours.

Kevin is paid $8.80 per hour. He worked 7 hours. He gave his mother 1/4 of his earnings. How much did Kevin have left?
Question 2 options:
25%
$46.20
$15.40
$61.60
Question 31poins
Answer:
46.20
Step-by-step explanation:
First determine how much he earned:
8.8 per hour times 7 hours
8.80 *7 =61.60
Then determine how much he gave his mother
61.60 * 1/4 =15.4
Subtract this from the total amount to determine how much is left
61.60-15.40
46.20

In Mr. Forester's science class,
students are given five tests in a
semester. Latoya's scores on the first
four tests are 86%, 82%, 91%, and
98%. If Latoya's score on the final
test is represented by x, then her
class average y can be found using
the equation below.
y =
86% + 82% + 91% + 98% + x
5
Mr. Forester awards an "A" to any
student whose class average falls
within the 90 - 100% range. Which
interval represents the domain of final
test scores that Latoya can get and
still receive an "A"?
F [90%, 100%]
G [87%, 100%]
H [93%, 100%]
[96%, 100%]
Answer:
The answer is "H [93%, 100%]"
Step-by-step explanation:
I'll edit this in a second to show the process, but it may take a minute. Just have the answer for now.
This is a surprisingly useful question hah, I'll bet many will need to do this.
This question is just finding the average. Pretty simple.
y = 86 + 82 + 91 + 98 + x / 5
y = 357 + x / 5
An easy way is to do the lowest question first, then go from lowest to second lowest and so on. Because if you go to the highest one and the answer is one of the lower ones, well, of course it's going to be within the 90-100 range, but that doesn't necessarily mean it's the answer.
y = 357 + (87) / 5
y = 444 / 5
y = 88.8
Okay, so the answer isn't G. Then let's try H.
y = 357 + (93) / 5
y = 450 / 5
y = 90
Yep, the answer is H. This is because it equals 90, which is indicative of the 90-100% range that Latoya needs to get an "A".

An equilateral triangle has perimeter P. The length of one side is P/3. Which expression is equivalent to the length on one side
Answer: [tex]3\times \dfrac{P}{3}=P[/tex]
Step-by-step explanation:
Given
The perimeter of one equilateral triangle is P
The lengths of the equilateral triangle are equal
Suppose x is the length of each side
[tex]\therefore 3\times x=P\\\\\Rightarrow x=\dfrac{P}{3}[/tex]
i.e.
[tex]\Rightarrow 3\times \dfrac{P}{3}=P[/tex]
Which is the equation of a parabola with vertex (0, 0), that opens to the left and
has a focal width of 12?
a. y2 = 12x
b. y2 = -12x
c.x = 12y
d. x = -12y
Answer:
Step-by-step explanation:
I'm going to guess that the square exponents are on the top y's only? then answer b) looks good
Answer:
b. y^2 = -12x
Step-by-step explanation:
The general form for the given parabola is y^2 = -4ax where the focus is at (-a, 0). The focal width is 4a which in this case = 12.

solve the equation 5(x-1)=17
Answer:
5(x-1) = 17
5x - 5 = 17 (write equation in simpler terms)
add 5 on each side like this (5x = 17 + 5)
= 5x = 22 which results in 4.4
