Answer:
60 oz of water to add
45 oz of 35% salt solution should be used
Step-by-step explanation:
Let x = amt no. ounces in the first solution
and 105 - x = amt no. of ounces in the second solution
Ist solution contains 0% salt
2nd solution contains .35(105 - x) salt
.15(105= amt of salt in mix
So.
amt of salt in 1st solution + amt of salt in 2nd solution = amt of salt in the mix
0 + .35(105 - x) = .15(105)
Let's get rid of the fractions by multipying thru the equation by 100
35(105 - x) = 15(105)
3675 - 35x = 1575
-35x = -2100
x = 60 oz of water to add
105 - 60 = 45 oz of 35% salt solution should be used

1. -1/2 = -6/18h
2. 16 = 3/10 a
3. 3/5 x = 12
4. 15/7y = 3
5. 14/3 = -7/9b
1) Answer:
[tex]h = \frac{3}{2} [/tex]
2) Answer:
[tex]a = \frac{160}{3} [/tex]
3) if you mean,
[tex] \frac{3}{5} x = 12[/tex]
Then the answer is. x = 20.
but, if you mean
[tex] \frac{3}{5x} = 12[/tex]
then the answer would be, x = 1/20.
4) Answer:
[tex]y = \frac{5}{7} [/tex]
5) If you mean,
[tex] \frac{14}{3} = - \frac{7}{9b} [/tex]
then the answer would be, b = -1/6
but if you mean,
[tex] \frac{14}{3} = - \frac{7}{9} b[/tex]
then the answer would be, b = -6

Work out (4.2×107)÷(7×104)Give your answer in standard form. Work out (4.2×107)÷(7×104)Give your answer in standard form.
Answer:
6 * 10^2
Step-by-step explanation:
Simplify : (4.2×10^7)÷(7×10^4)
(4.2 × 10^7) / (7 × 10^4)
From indices : 10^a ÷ 10^b = 10^(a - b)
(4.2 / 7) * 10^(7-4)
0.6 * 10^3
= 6 * 10^2
Hence, (4.2×10^7)÷(7×10^4) = 6 * 10^2
Riley earned $38.25 for cleaning the garage. She was paid $4.25 per hour. Write and solve an equation to find how long it took her to clean the garage. Include a label in your answer.
Answer:
It took Riley 9 hours to clean the garage.
Step-by-step explanation:
With the information provided, you can say that the amount Riley earns for cleaning the garage is equal to the price per hour for the number of hours it takes to clean the garage, which can be express as:
x=4.25y, where:
x is the amount Riley earns for cleaning the garage
y is the number of hours it takes to clean the garage
Now, you can replace x with $38.25 that is the amount that Riley earned and you can solve for y to find how long it took her to clean the garage:
38.25=4.25y
y=38.25/4.25
x=9
According to this, the answer is that it took Riley 9 hours to clean the garage.

B. B'C' = 17. m2A=62
C. B'C' = 8. m ZA=28
D. B'C' = 8. m ZA' = 14
Answer:
your answer will be C. B´C=8. m ZA=28
Step-by-step explanation:
hope it helps have a nice day
After dilation of ΔABC, the length of B'C' = 8m and ∠A' = 28°.
What is Dilation?Dilation means changing the size of an object without changing its shape. The size of the object may be increased or decreased based on the scale factor.
When the triangle undergoes dilation, the length of its sides gets multiplied by 1/2 (dilation factor) but the angles remain the same ( since, the shape has to remain same).

A gym charges an initial fee plus $25 per month. John paid $200 for six months. Assume the relationship is linear.
a.What is the rate of change and what does it mean in context to the situation?
b. What is the initial value and what does it mean and context to the situation?
i will give brainliest!!!!!
Step-by-step explanation:
a. The rate of change is $33.33 per month
200/6 = approximately $33.33 per month
This means that in addition to the initial fee, Josh has to pay $33.33 per month for the gym membership.
b. The initial value is $25. This is a constant value and a one time fee to open and attain a gym membership.

What is another way to write 15 divided by 2?
15
O 15+2
O 15 x 2
Answer: [tex]15\times\frac{1}{2}[/tex]
Explanation:
Multiplying by 1/2 is the same as dividing by 2.
For example, if you have 10 slices of cake and 2 friends, then each friend gets 10/2 = 5 slices. We could also say [tex]10\times \frac{1}{2} = 5[/tex]
The fraction 1/2 converts to the decimal form 0.5, which means [tex]10 \times \frac{1}{2} = 10*0.5[/tex]
