Step-by-step explanation:
Two tailors, Valentina and Laura, sit down to do some embroidery. Valentina can embroider 2 shirts per hour, and Laura can get through 3 shirts per hour. In addition, the tailors had previously finished some shirts. Valentina has already completed 15 shirts, and Laura has completed 11 shirts. Valentina and Laura decide to take a break when they have finished the same total number of shirts. How many shirts, in total, will each tailor have finished? How long will that take?
Answer:
Valentina and Laura finished the same total number of shirts in [tex]4[/tex] hours.
Total number of shirts finished by Valentina [tex]=23[/tex]
Total number of shirts finished by Laura [tex]=23[/tex]
Step-by-step explanation:
Suppose that Valentina and Laura finished the same total number of shirts in [tex]t[/tex] hours.
Valentina can embroider 2 shirts per hour and Valentina has already completed 15 shirts.
Total number of shirts finished by Valentina [tex]=2t+15[/tex]
Laura can get through 3 shirts per hour and Laura has completed 11 shirts.
Total number of shirts finished by Laura [tex]=3t+11[/tex]
Therefore,
[tex]2t+15=3t+11\\3t-2t=15-11\\t=4[/tex]
So,
Valentina and Laura finished the same total number of shirts in [tex]4[/tex] hours.
Total number of shirts finished by Valentina [tex]=2(4)+15=8+15=23[/tex]
Total number of shirts finished by Laura [tex]=3(4)+11=12+11=23[/tex]

Answer:
36
Step-by-step explanation:
16*2 = 32
16*1/4 = 4
32+4 = 36
Answer: She will need 36 yards of material.
Step-by-step explanation:
16 × 2¹/₄ can be done different ways,
First multiply ¹/₄ times 16. that is the same as dividing 16/4 = 4
Then multiply 2 times 16 2×16 = 32
Add 32 + 4 = 36
Another way is to change 2¹/₄ to an improper fraction and multiply
⁹/₄ × 16

tommy had 8 times more money than loren. when parents gived 35cents to loren and tommy spent 14cents both of kids had same money. how much tommy had in start? how much loren had in start?
Answer:
Tommy had 56 cents in start and Loren had 7 cents in start.
Step-by-step explanation:
Let,
x be the money Tommy have.
y be the money Loren have.
According to given statement;
Tommy had 8 times more money than Loren.
x = 8y Eqn 1
Parents gave 35 cents to Loren and Tommy spent 14 cents, therefore
x-14=y+35 Eqn 2
Putting x=8y in Eqn 2
[tex]8y-14=y+35\\8y-y=35+14\\7y=49[/tex]
Dividing both sides by 7
[tex]\frac{7y}{7}=\frac{49}{7}\\y=7[/tex]
Putting y=7 in Eqn 1
[tex]x=8(7)\\x=56[/tex]
Hence,
Tommy had 56 cents in start and Loren had 7 cents in start.

Replace x with the values in the table and solve.
25-3(2)= 25-6 = 19
25-3(4) = 25-12 = 13
25-3(5) = 25-15 = 10
25-3(6) = 25-18 = 7
10x = 10,000?
What is It?
Answer:
x = 1000
Step-by-step explanation:
To solve for x, you do the same thing to both sides to isolate x.
To isolate x in this equation, you divide both sides by 10.
10x = 10,000
10x/10 = 10,000/10
x = 1,000

Blanche bought a 5-year cd for $7100 with an apr of 2.8%, compounded quarterly, but she wants to take all her money out 9 months early. The early redemption fee for the cd is 3 months' interest on the original principal. What is the periodic interest rate of the cd
Answer:
The money she will end up earning in interest on the cd = $11,352.90
Step-by-step explanation:
The formula for getting the accumulated amount(compounded) is;
[tex]A =P(1+\frac{r}{n})^n*t[/tex]
Where
A = Accumulated amount
P = principle (deposit)
r = interest rate and
n = no of times interest applied per time period.
The interest is compounded quarterly so in one year it will be 4 times
In 5 years
n = (5×4)-3 = 17 (as she will withdraw 3 month before the completion of five years)
A = [tex]7100(1+\frac{2.8}{100} )[/tex]^17
= 7100( 1 + 0.028)^17
= 7100(1.028)^17
= 7100 * 1.599
= 11,352.90
Therefore the money she will end up earning in interest on the cd = $11,352.90
Evaluate the following expression when n = 6.
|n - 6| - |5 - n|
Answer:
-1
Step-by-step explanation:
1. Substitute n with 6 because n=6
2. Then you simply solve both sides so (6-6)-(5-6) because n=6
3.so then you get the absolute value of 0 subtracted by the absolute values of -1
4. So because all absolute values change it to positive you get 0-1 instead of 0- - 1
5. So the final answer is -1
Sorry if this was confusing, I’m really bad at explaining. :)
Answer:
|n-6|-|5-n|

A company tests the life of its rechargeable batteries over six months of use. They test how long a battery will last after a full charge and put the data into a scatter plot. On the best-fit line y=-12.05+224.26 about how many months will a typical battery last before it is completely dead? Round your answer to the nearest tenth of a month.
Answer:
18.6 months
Step-by-step explanation:
Given that :
Best fit line from scatterplot :
y=-12.05x +224.26
x = Number of month
y = charge on battery
Number of months a typical battery uses before being dead completely :
When battery is dead completely ; charge =0, y = 0
y = -12.05x + 224.26
0 = - 12.05x + 224.26
12.05x = 224.26
x = 224.26 / 12.05
x = 18.610788
Hence, 18.6 months before battery is completely dead.
