A frosting recipe calls for adding 5 tsp of red food coloring for every 3 tsp of blue food coloring. If you used 15 tsp of blue food coloring, how many tsp of red food coloring would you use to get the same recipe of frosting ?
Answer:
tsp of red food coloring = 25
Step-by-step explanation:
Red food coloring = 5 tsp
Blue food coloring = 3 tsp
Red food coloring : Blue food coloring = 5 tsp : 3 tsp
Blue food coloring = 15 tsp
how many tsp of red food coloring would you use to get the same recipe of frosting ?
Let
x = tsp of red food coloring
Red food coloring : Blue food coloring = x tsp : 15 tsp
Equate the ratios to find x
Red food coloring : Blue food coloring
5 tsp : 3 tsp = x tsp : 15 tsp
5 / 3 = x / 15
Cross product
5 * 15 = 3 * x
75 = 3x
Divide both sides by 3
x = 75 / 3
= 25
x = 25 tsp
tsp of red food coloring = 25

Given that 4x−5y=39
Find y when x=3
Give your answer as an improper fraction in its simplest form.
Answer:
- [tex]\frac{27}{25\\}[/tex]
Step-by-step explanation:
4x−5y=39
for x=3
12 - 5y = 39
-5y = 39 -12
-5y = [tex]\frac{27}{5\\}[/tex]
-y = [tex]\frac{27}{25\\}[/tex]
y = - [tex]\frac{27}{25\\}[/tex] = -1 [tex]\frac{2}{25\\}\\[/tex]
-27/5 or -5 2/5
Step-by-step explanation:
4x-5y=39 while x=3
4(3)-5y=39 add x into bracket
12-5y=39 result of 4*3
12-5y-12=12-39 substrate non variable number to each side
5y = -27 the result from upper substraction
y= -27/5 the result mixed fraction form -5 2/5

f(x) = 8x^2 + 8x - 12 in vertex form
Answer:
f(x) = (x + 4)² - 4
Step-by-step explanation:
Write the equation f(x) = x² + 8x + 12 in vertex form by completing the square:
f(x) = (x² + 8x + (8/2)²) + 12 - (8/2)²
Simplify:
f(x) = (x² + 8x + 16) + 12 - 16
Subtract to find the 'k' value:
f(x) = (x + 4)² - 4. This is the equation in vertex form.
Answer:
y=8x2+8x−12
Step-by-step explanation:
Rewrite in vertex form and use this form to find the vertex (h,k).

The average of four numbers 30.5. three of the numbers are 24.2, 14.5, 50.5
what is the fourth number?
Answer:
32.8
Step-by-step explanation:
The average is calculated as
average = [tex]\frac{sum}{count}[/tex]
let x be the fourth number, then
[tex]\frac{24.2+14.5+50.5+x}{4}[/tex] = 30.5 ( multiply both sides by 4 )
89.2 + x = 122 ( subtract 89.2 from both sides )
x = 32.8
Thus the fourth number is 32.8

what is the following sum ?
what are the angle measures given the figure is a rhombus???
Answer:
∠ 1 = 136°
Step-by-step explanation:
The diagonals of a rhombus bisect the angles, thus other side of the diagonal to 22° is also 22°. Making the whole angle = 44°
Consecutive angles are supplementary, thus
∠ 1 + 44° = 180° ( subtract 44° from both sides )
∠ 1 = 136°

You and your friend go shopping with $846,375,593. (that's literally the question) You spend 250,678 dollars on shoes, 10,008 dollars on clothes, and 40,034 dollars on accesories. How much money do you both have left?
Later, your friend and you get robbed and the robber takes half of the remaining money. How much do you have left?
Later, you earn $234,485.78. How much do you and your friend now have?
This is the actual question on my homework... I have no clue how to do this... can someone please help me? 50 points!
Answer:
Initial money -->$846,375,593
You spend 250,678 dollars on shoes, 10,008 dollars on clothes, and 40,034 dollars on accesories.
$846,375,593-$250,678-$10,008-440,034 = $845,674,873
Later, your friend and you get robbed and the robber takes half of the remaining money. How much do you have left?
$845,674,873/2 = $422,837,436.5
You have $422,837,436.5 left.
Answer: Ok look at the explaination
Step-by-step explanation:
$846,375,593 - everything you spend = 846,074,873
You both have 846,074,873 after the shopping spree
To calcute how much is left after the robbery you divide the money you have left by two since the robber took half. Then your are left with 423,037,436
Then you earn money so add 234,458.78 to your 423,037,436 and you have 423,271,922
At the end you are left with $423,271,922
Two friends argue over who brushes their teeth more often.
Who is more likely to brush both morning and evening? Assume all events are independent.
Multiple choice answers in picture below
Answer:
arabella so B
Step-by-step explanation:
plz mark brainlyest
The probability of one who is more likely to brush both time morning and evening is Braxton, he has a 0.61 probability of brushing both times.
What is Probability?Probability helps us to know the chances of an event occurring.
[tex]\rm Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}[/tex]
The probability of Braxton brushing both times = (0.72×0.85) = 0.612
The Probability of Arabella brushing both times = (0.82×0.79) = 0.6478
Hence, the probability of one who is more likely to brush both time morning and evening is Braxton, he has a 0.61 probability of brushing both times.

In a board game, Judy scored 5 points more than twice the number of points Ann scored. There was a total of 65 points scored. If Judy scores x points and Ann scores y points . How many points did Judy score?
Judy scored 45 points in the board game.
What is the system of equations?One or many equations having the same number of unknowns that can be solved simultaneously called as simultaneous equation. And simultaneous equation is the system of equation.
Given:
In a board game,
Judy scored 5 points, more than twice the number of points Ann scored.
If Judy scores x points and Ann scores y points,
that means,
x = 2y + 5
x - 2y = 5. {equation 1}
There was a total of 65 points scored.
x + y = 65 {equation 2}
Subtract the equation 2 to equation 1,
we get,
-3y = -60
y = 20
Then, x = 45.
Therefore, 45 points Judy scored.

(a) the probability that a vampire bat would pick A (b) the probability that a vampire bat would pick C (c) the probability that a vampire bat would pick T
Answer:
See Explanation
Step-by-step explanation:
See attachment for complete question.
From the attachment, we have that:
[tex]A = 71[/tex]
[tex]C = 121[/tex]
[tex]T = 66[/tex]
First, we calculate the total
[tex]Total = A + C + T[/tex]
[tex]Total = 71 + 121 + 66[/tex]
[tex]Total = 258[/tex]
Solving (a): Probability of A
This is calculated using:
[tex]Probability = \frac{A}{Total}[/tex]
[tex]Probability = \frac{71}{258}[/tex]
[tex]Probability = 0.275[/tex]
Solving (b): Probability of C
This is calculated using:
[tex]Probability = \frac{C}{Total}[/tex]
[tex]Probability = \frac{121}{258}[/tex]
[tex]Probability = 0.469[/tex]
Solving (b): Probability of T

Maritza says that the number y is equal to 5 less than -5 times x. Which of the following equations could be used to find the value of y?
Answer:
y= -5x-5
Step-by-step explanation:
Y is equal to 5 less than -5 times x, which means it is 5 less than -5x.
If y is 5 less than -5x, that means it is equal to -5x-5.
If you were to put that in an equation, it would be y= -5x-5

Which equation represents the vertex form of the equation y= x2 - 6x + 11?
A. y= (x - 3)2 + 2
B. y= (x - 6)2 + 2
C. y= (x - 6)2 +11
D. y= (x - 3)2 + 11
Answer:
A
Step-by-step explanation:
Use the method of completing the square to express in vertex form.
Given
y = x² - 6x + 11
To complete the square
add/subtract ( half the coefficient of the x- term )² to x² - 6x
y = x² + 2(- 3)x + 9 - 9 + 11 , then
y = (x - 3)² + 2 → A

3 hats and 2 scarves costs £12.
5 hats and 4 scarves costs £21.
Find the cost of a hat.
Find the cost of a scarf
Answer:
hat=£(9*9)/3*24)/3/8/9
Scarf=£1.5
Step-by-step explanation:
Let's suppose hats is the variable h
And Let's suppose scarves is the variable s
3h+2s=12
5h+4s=21
so, 3h+2s=12 which is also 2s=12-3h
so, in the equare 5h+4s=21 we can replace the 4s with 2(12-3h) Now the equation is this:
5h+24-6h=21
*Simplified*
Now 5h-6h= -1h
-1h+24=21
+1h +1h
on each side.
now the equation is(remember 1h=h): 24=h+21
I think you can do it now.
Now with the cost of the hats, we can use the first equation: 3h+2s=12
h=3
3*3=9
-9 -9
2s=3
s=1.5
