Aubrey finished 2/9 of a project on Monday and 1/4 of the project of Tuesday. How much of the project has Aubrey completed?
Answer:
17/36
Step-by-step explanation:
We have to find a common denominator, so the first common denominator for 4 and 9 is 36. 9x4=36, so we multiply 2 by 4, which equals 8. 4x9-36, so we multiply the 1 by 9, and get 9. Then we add the numerators, 8 and 9, and get 17. So it's 17/36

A small dog gets fed 3/4 cups of dog food twice a day. Using d for the number of days and f for the amount of food in cups, write an equation relating the variables. Use the equation to find how many days a large bag of dog food will last if it contains 210 cups of food.
Answer:
f=1.5⋅d or equivalent. The bag will last 140 days since 210÷1.5=140.
Step-by-step explanation:

Jocelyn estimates that a piece of wood measures 5.5cm. If it actually measures 5.62 cm, what is the percent error of Jocelyn’s estimate?
Answer:
2.14% error
Step-by-step explanation:
Use the percent error formula:
| (observed - expected) / expected | x 100
Plug in the observed and expected values:
| (observed - expected) / expected | x 100
| (5.5 - 5.62) / 5.62 | x 100
Calculate:
= 2.14% error
So, the percent error of Jocelyn's estimate is 2.14%

a TV reduced by 30% to £560. What was the original cost of the TV?
Answer:
£800
Step-by-step explanation:
when you recuce the price of something by 30%, it is 70% of the original (100% minus whatever percent reduction).
.7x=560 where x is the original price of the tv
560/.7=800
the original price of the tv is £800

There are 10 cards. Each card has one number between 1 and 10, so that every number from 1 to 10 appears once.
In which distributions does the variable X have a binomial distribution?
Select each correct answer.
When a card is chosen at random without replacement three times, X is the number of times an even number is chosen.
When a card is chosen at random with replacement multiple times, X is the number of times a card is chosen until a 5 is chosen.
When a card is chosen at random with replacement five times, X is the number of times a prime number is chosen.
When a card is chosen at random with replacement six times, X is the number of times a 3 is chosen.
Answer:

A) 10 millimeters
B) 5 millimeters
C) 50 millimeters
D) 2 millimeters
Answer:
50 millimeters
Step-by-step explanation:
d alone , is always 1. Just like any other variable. To find the hegiht you need to do days x 10.
After 5 days its mental math.
just do 5 x 10 and do not forget to add millimeters to the end!

Isaiah earns $60 per week mowing lawns in the summer and shoveling driveways in the winter. He invested $220 in equipment. How long will it take him to earn $860? Find the equation and solve.
Answer:
18 weeks
Step-by-step explanation:
Create an equation where x is the number of weeks he works
60x - 220 will represent his profit, since he gets $60 a week but spent $220 in equipment.
Set this equal to 860, then solve for x, to find when he will earn $860
60x - 220 = 860
60x = 1080
x = 18
So, it will take him 18 weeks to earn $860

Step-by-step explanation:
Jamal is running 42 kilometers. The amount of time t it takes Jamal to run varies inversely with the rate, r, at which he runs, write the inverse variation equation that represents this situation
Answer:
t α 1 /r ; t = k/r
Step-by-step explanation:
Given that :
Time taken, t varies inverse as rate, r
MATHEMATICALLY,
t α 1 /r
Hence,
t = k/r ;
Where, k is the proportionality constant
Hence, the situation could be expressed as :
t = k/r OR
t α 1 /r
50% of 50% of x. PLEASE HELP I WILL GIVE BRAINLIEST
Answer:
25. 50 percent of 50 is 25 divided by 2.
Step-by-step explanation:
step1:Our output value is .50.
step2:we represent the unknown value with x
step3: from step1 above,.50=100%
step4: similarly,x=50%
step5: This results in a pair of simple equation:
.50=100%(1)
x=50%(2)
step6:by dividing equation 1 by equation 2 and noting that both the RHS(right hand side)of both equations have the same unite(%);we have
.50. 100%
____. = ____
x. 50%
step7: again,the reciprocal of both sides gives
x. 50
___ =. ___
50. 100
°x=0.25
therefore,50%of.50 is 0.25

Answer:
-40m = 59.2
Step-by-step explanation:
simplify
Answer:
-40m + 59.2
Step-by-step explanation:
Distribute
-40m + 59.2
If you're solving for m then set the equation equal to 0 and solve.
-40m + 59.2 = 0
-40m = -59.2
m = 37/25
Sasha uses 6.1 pints of white paint and blue paint to paint her bedroom walls. 2/5 of this amount is white paint, and the rest is blue paint. How many pints of blue paint did she use to paint her bedroom walls?
Answer: 3.66 pints of blue paint.
Step-by-step explanation:
She used 2/5 of the total number of pints to paint white.
That number in pints is:
= 2/5 * 6.1
= 2.44 pints of white
The number of pints used to paint blue is therefore:
= 6.1 - 2.44
= 3.66 pints of blue paint.

let f(X)=x^2+2 and g(X)=1-3x
Answer:
1. y = x2+2
2. g = (-3x+1)/x
Step-by-step explanation:
1. No explanation
2.
Let's solve for g.
gx=1−3x
Step 1: Divide both sides by x
gx /x = −(3x+1 )/x
g = (-3x+1)/x
