Answer:
4,24,48
Step-by-step explanation:
For the first equation, they are splitting 8 in half. So 8/2 would be 4. The 4 would go in the first box.
Then 4x6 is 24 in the second box.
Then just add 24 and 24. 24+24=48
And your last answer is 48.
Solve for y: 3x - y^2 = 25
Answer:
Square root ( 3x - 25)
Step-by-step explanation:
3x - y^2 = 25
- y^2 = 25 - 3x
y ^2 = 3x - 25
y = Square root ( 3x - 25)

the ratio of zoes money to yolansa's is 3:7. Yolanda has $64 more than Zoe. If Yolanda gives (1)/(4) to zoe what is the new ratio of zoes money to yolanda
New Ratio = 19:21
This deals with ratios, fractions and basic arithmetics'.
The ratio of money of zoe to yolansa's own is 3:7.Thus, the total part for each of them will be;
Zoe; 3/10
Yolansa; 7/10
If the total money they both have is x, then they will have;Zoe; 3x/10
Yolansa; 7x/10
Now,Yolanda has $64 more than Zoe. Thus;[tex]\frac{7x}{10}[/tex] - [tex]\frac{3x}{10}[/tex] = 64
Simplifying this gives;
[tex]\frac{4x}{10}[/tex] = 64
Rearranging gives;
4x = 640
x = 640/4
x = $160
Thus, originally;
Yolanda has [tex]\frac{7}{10}[/tex] × 160 = $112
Zoe has [tex]\frac{3}{10}[/tex] × 160 = $48
Yolanda now gives [tex]\frac{1}{4}[/tex] of her money to Zoe.
Thus, she gives out [tex]\frac{1}{4}[/tex] × 112 = $28
Thus,
Zoe now has; 48 + 28 = $76
Yolanda now has; 112 - 28 = $84
New ratio of zoes money to yolandas money is;76:84
Simplifying this ratio gives;
19:21

We are required to find the new ratio of zoes money to yolanda
the new ratio of zoes money to yolanda is 19:21
Ratio of zoes money to Yolanda's = 3:7.
Zoes = 3
Yolanda = 7
Total ratio = 3 + 7 = 10
let
x = Total money
Zoes = 3/10
Thus, the total part for each of them will be;
Zoe= 3/10x
Yolanda = 7/10x
Yolanda has $64 more than Zoe.
Therefore,
7/10x - 3/10x = 64
(7x - 3x) / 10 = 64
4x/10 = 64
cross product
4x = 64 × 10
4x = 640
divide both sides by 4
x = 640/4
x = $160
Original share:
Zoe = 3/10x
= 3/10 × 160
= 0.3 × 160
= $48
Yolanda = 7/10x
= 7/10 × 160
= 0.7 × 160
= $112
If Yolanda gives 1/4 to zoe
= 1/4 of 112
= 1/4 × 112
= 0.25 × 112
= $28
New Zoe's share = $48 + $28
= $76
New Yolanda's share = $112 - $28
= $84
Their new ratio = 76 : 84
divide by 4
= 19 : 21

Determine if 0.34375 is rational or irrational and give a reason for your answer.
Answer:
Rational
Step-by-step explanation:
The key detail in this problem is that the decimal is terminating so it's not infinitely continuous. A irrational number is a value that when in decimal form, it is infinitely continuous and never ends. Since the decimal we are working with terminates, it is rational.

(50 Points) ∠1 and ∠2 are supplementary angles. m∠1 is 4y+7, and m∠2 is 9y+4. Find m∠2.
∠1 and ∠2 are supplementary angles. m∠1 is 4y+7, and m∠2 is 9y+4. Find m∠2.
Solution:The sum of supplementary angle is 180°
First, solve for the value of y.
∠1 + ∠2 = 180°(4y + 7) + (9y + 4) = 180°13y + 11 = 180°13y = 180° - 1113y = 169/13y = 13°Then, plug and substitute the value y = 13 to find the m∠2.
m∠29y + 49(13) + 4117 + 4121Answer:The angle of m∠2 is 121The measure of angle 2 is 121 degrees.
Given:
[tex]m\angle1=4y+7\\m\angle2=9y+4[/tex]
Recall: Supplementary angles are angles whose sum equals [tex]180^{o}[/tex]
To solve this problem, create an equation to find the value of x:
Thus:
[tex]m\angle1 +m\angle2=180[/tex]
Therefore:
[tex](4y+7)+(9y+4) = 180\\[/tex]
Solve for y:
[tex]4y+7+9y+4 = 180\\\\[/tex]
Add like terms:
[tex]13y+11 = 180\\\\[/tex]
Subtract 11 from both sides
[tex]13y+11 - 11= 180 - 11\\13y = 169[/tex]
Divide both sides by 13
[tex]\frac{13y}{13} = \frac{169}{13} \\y = 13[/tex]
Find the m∠2 by substituting [tex]y = 13[/tex] into [tex]9y +4[/tex]
[tex]m\angle= 9(13)+4\\m\angle = 121^{o}[/tex]
Therefore, m∠2 = 121 degrees.

A box of candy was divided into three bottles P, Q and R in the ratio 9:4:11. If, instead, the candy had been divided equally between them, there would be 21 fewer pieces of candy in bottle R. How many pieces of candy were there in the box?
There are a total of 44 candies in the box.
How many pieces of candy were there in the box?The total ratio is 24
Let;
the total number of candies be xthe number of candies in R be11/22 * x = y ---- (1)
If the candies were shared equally
The ratio of candies in R will be 6
6/24 * x = y - 11 --- (2)
substitute y = 11/22 * x in (2)
6x/24 = 11x/22 - 11
x/4 = x/2 - 11
multiply through with 4
x = 2x - 44
x = 44
Therefore, there are a total of 44 candies.
