Jada has 12 library books checked out and Han has LaTeX: \frac{1}{3}1 3 less than that. How many books does Han have checked out?
Answer:
8
Step-by-step explanation:
The questions is difficult to read but if it means "Jada has 12 library books checked out and Han has 1/3 less than that" Han would have 8 because 12/3 is 4. 12-4 is 8. This would only be correct if that is what the problem means. Sorry. I'm not sure what "LaTeX: \frac{1}{3}1 3" means.

1: 15 - 3/7 =
2: Hayden has 5 hours to practice his oboe. It takes him 3/5 of an hour to practice one song. How many songs can he practice in 5 hours?
3: 12/15 x 6/18 =
4: 4 4/8 x 1 3/11 =
Answer:
( I am assuming that these are all fractions)
1. 14 [tex]\frac{4}{7}[/tex]
2. 8
3. [tex]\frac{4}{15}[/tex]
4. 5 [tex]\frac{8}{11}[/tex]
Step-by-step explanation:
1. First you have to convert 15 into a fraction but it must have the same denominator causing the equation to look like 105/7 - 3/7= 102/7. But you cannot just leave the fraction like that it must be simplified 14 [tex]\frac{4}{7}[/tex]
2. Three-fifths of an hour is 36 minutes. You would next multiply 5 by 60 which would the hours into minutes 5 x 60 = 300. You would then divide 300 by 36 which would give you 8.3333333333, which I just simplified it to 8
3. In order for you to multiply a fraction you would first multiply the top then the bottom. 12 x 6= 72, 15 x 18= 270. The fraction would look like 72/270 which is simplified to [tex]\frac{4}{15}[/tex] .
4. First I changed the fractions into improper fractions causing the fraction to look like 36/8 x 14/11 (I got these answers by 8 by 4 then adding 4, then for the next fraction I multiplied 11 by 1 then added 3.) 36 x 14= 1224, 11 x 8= 88 the fraction would look like 1,224/88 you would simplify to 5 [tex]\frac{8}{11}[/tex]

I WILL GIVE BRAINLIEST! DO NOT ANWSER IF YOU DON'T KNOW! Guy and Jim work at a furniture store . Guy is paid $185 per week plus 3% of his total sales, in dollars, x, which can be represented by g(x) = 185 + 0.03x. Jim is paid $275 per week plus 2.5 % of his totals sales in dollars, x, which can be represented by j(x) = 275 + 0.025 x . Determine the value of x, in dollars, that will make their weekly pay the same.
Answer:
185 + 0.03x = 275 + 0.025x
Step-by-step explanation:
0.03x - 0.025x = 275 - 185
0.005x = 90
Divide both sides by 0.005
x = 90/0.005
x=18000

Solve each system of equations
2x- 5y = 7
3x - y = -9
Answer:
x = -4; y = -3
Step-by-step explanation:
2x - 5y = 7
3x - y = -9
Rewrite top equation. Multiply both sides of bottom equation by -5. Add equations. This eliminates y, and we solve for x.
2x - 5y = 7
(+) -15x + 5y = 45
----------------------------
-13x = 52
Divide both sides by -13.
x = -4
Substitute -4 for x in the first original equation and solve for y.
2x - 5y = 7
2(-4) - 5y = 7
-8 - 5y = 7
-5y = 15
y = -3
Answer: x = -4; y = -3

If the diameter of a circle is 12, what is the area and circumference?
Answer:
circumference: 37.7
area: 113.1
Step-by-step explanation:
for the future look up '___ of a circle'
and enter the radius (if u are given the diameter divide it by 2)
Answer:
circumference = 37.68 (37.7 if you're rounding it)
Area = 113.04 (113.1 if you're rounding it)
Step-by-step explanation:
The formula for circumference is C=2πr (2 times pi times radius)
If the diameter is 12, the radius is 6.
2 x 3.14 x 6 = 37.7
The formula for area is A=πr2 (pi x radius to the second power)
The radius is 6. Six to the second power is 36.
36 x 3.14 = 113.04

Estelle drew two parallel lines, PQ and RS, intersected by a transversal KL, as shown below: Two parallel lines, PQ and RS, are drawn with KL as a transversal intersecting PQ at point M and RS at point N. Angle KMQ is shown congruent to angle MNS. Which fact would help Estelle prove the measure of angle KMQ is equal to the measure of angle MNS? When both angle KMQ and angle MNS are equal to angle RNM, the angles KMQ and MNS are congruent. When same-side, consecutive interior angles QMN and PMN are complementary, the angles KMQ and MNS are congruent. When alternate interior angles QMN and MNR are supplementary, angles KMQ and MNS are congruent. When both angles KMQ and MNS are equal to angle PMN, the angles KMQ and MNS are congruent.
Answer:
I'm pretty sure the answer is d,(When both angle KMQ and MNS are equal to angle PMN, the angles KMQ and MNS are congruent.)

Find the area of a circle with a diameter of 56 millimeters. Round your answer to the nearest hundredth.
area: about ???
mm2
9514 1404 393
Answer:
2463.01 mm²
2461.76 mm² if you use 3.14 for π
Step-by-step explanation:
The formula for the area of a circle is ...
A = πr²
where r is the radius, half the diameter.
For a diameter of 56 mm, the radius is 28 mm. Using that in the formula gives an area of ...
A = π(28 mm)² = 784π mm²
For an appropriate value of π, the area is ...
784π mm² = 2463.00864... mm² ≈ 2463.01 mm²
For 3.14 as the value of π, the area is ...
784(3.14) mm² = 2461.76 mm²
_____
Comment on pi
Quite often these problems expect you to use 3.14 for pi. The required answer has 6 significant digits, so the use of a 3-digit value for pi is not appropriate. Rather, the value used should be 3.141493 or even more accurate.
Lucy wants to buy a basketball that costs $30. She lives in a state that has 10% sales tax. What is the final price she will pay for the basketball including tax?
Answer:

3.-7 - 5 = -12
4. 7 - (-5) = 12
Step-by-step explanation:
#4 - The reason it's 12 is because the -5 is in parenthesis which means they want you to find the absolute value of the number and then add it. The absolute value of a negative number is positive.
#3 really you're adding 5 to -7.
#2 opposite of #3, you can think of it as subtracting 5 from -7.

Which of the following is equivalent to 5:4? *
25:15
20:19
30:20
10:8
15:16
100:85
Answer:
10:8
Step-by-step explanation:
5*2=10
4*2=8
10:8
Answer:
the answers equivalent to 5:4 is 10:8
Step-by-step explanation:
The reason I only chose 10:8 is because all the other answers are not even multiples of 5 or 4 or they were multiples of 5 and 4 but they were not multiplied by the same number.
Example:
25:15 = okay so 5 can go into 25, 5 times but 4 cannot go into 15
20:19 = okay so 5 can go into 20, 4 times but 4 cannot go into 19
30:20 = though 5 can go into 30 and 4 into 20 they are not multiplied by the same number
15:16 = though 5 can go into 15 and 4 into 16 they are not multiplied by the same number
and last but not least 100:85 = okay so 5 can go into 100, 20 times but 4 cannot go into 85
So it leaves 10:8= 5 can go into 10, 2 times and 4 can go into 8, 2 times so this is your answer.
Hope this helps you!!!
5 * 2 = 10 and 4 * 2 = 8
