18. A juice recipe calls for 3 1/2 cups
of sugar and will serve 60 people.
How much sugar would you need
if you reduced the recipe to serve
only 48 people?
A 4 2/3c B 3 1/2c C 2 4/5 c D 2 1/2c
Answer:
C. 2 [tex]\frac{4}{5}[/tex] cups
Step-by-step explanation:
We want 3.5 (3 1/2) cups of sugar that serves 60 people to serve 48 people instead. So we use proportions. Set it up:
[tex]\frac{x}{3.5} = \frac{48}{60}[/tex]
60x = 168 (48 x 3.5)
/60 /60
x = 2.8 cups of sugar serves 48 people.
Change 2.8 into fractions: 2 [tex]\frac{4}{5}[/tex]

This graph shows the amount of charge left on my computer, c, after I have been awake for h hours.
How many hours will I have been awake when my computer has no charge left?
Use the sketch tool if it helps you with your thinking.
Based on the graph given above, the hours you will have to be awake when your computer has 0% charge is: 4.5 hours.
How to Interpret a Graph?Analyzing the graph given in the image above, where c represents the amount of charge you have left on your computer, and h represents the number of hours after you have been awake, the graph shows the following:
The unit rate = -30, which means the charge on your computer dropped at 30% per hour.The initial charge on your computer was the y-intercept of the graph, which is 90%.Your computer will have 0% after 4.5 hours that you have been awake (this is the x-intercept of the graph).Therefore, the number of hours you will have been awake for your computer to have no charge left is: 4.5 hours.

5. What is the value of x?
Answer:
5[tex]\sqrt{3}[/tex]
Step-by-step explanation:
in a 30-60-90 triangle the ratio of sides, respectively, is 1 : [tex]\sqrt{3}[/tex] : 2
you can set up a proportion like this to solve for 'x':
[tex]\sqrt{3}[/tex] / 1 = 15 / x
cross-multiply:
[tex]\sqrt{3}[/tex]x = 15
x = 15/[tex]\sqrt{3}[/tex]
rationalize the denominator by multiply top and bottom by [tex]\sqrt{3}[/tex]
you get 15[tex]\sqrt{3}[/tex] ÷ 3 which is 5[tex]\sqrt{3}[/tex]

Harvey is studying the polynomial f(x) = (2x - 3)(x - 4)(x2 + 3) and determines that the polynomial has four real roots. Is
Harvey's statement CORRECT?
A. No, the polynomial f(x) has 2 real roots and 2 complex roots when solved.
O B. Yes, the polynomial f(x) has 4 x-intercepts so the function has 4 real roots.
C. Yes, the polynomial f(x) has a degree of 4 so the function has 4 real roots.
OD. No, the polynomial f(x) has 3 real roots because there are 3 factors.
Answer:
It is A, I highly suggest you should read my explanation.
Step-by-step explanation:
(2x - 3)(x - 4)(x^2 + 3)
Exponent of 2x = 1
Exponent of x = 1
Exponent of x^2 = 2
Add them all together to get the degree. 1 + 1 + 2 = 4
Now we can tell that the polynomial can have 1,2,3,4, or no roots at all. The max number roots it can have is 4
To see the number of roots it has, we have to set each part equal to 0
2x - 3 = 0
Add 3 to both sides
2x - 3 + 3 = 0 + 3
2x = 3
Divide both sides by 2
2x/2 = 3/2
x = 3/2 or 1.5
Next,
x - 4 = 0
Add four to both sides
x - 4 + 4 = 0 + 4
x = 4
Then,
x^2 + 3 = 0
Subtract 3 from both sides
x^2 + 3 - 3 = 0 - 3
x^2 = -3
Find the square root of both sides
sqrt(x^2) = sqrt(-3)
x = i*sqrt(3), -i*sqrt(3)
Those are imaginary numbers, therefore there are not real.
The real roots are x = 3/2, 4
Harvey stated that this equation has four real roots. We can cross options B and C out since they stated he was correct.
It is not D because finding a square root of a number gives two answers; the positive and negative version, so it will have two solutions. There were only two real roots and the other two roots are complex roots.
That leaves us to option A, which states that there are 2 real and 2 complex roots. It is correct
8. Can Sandra claim Debbie as a qualifying relative on her 2019 return? a. Yes, because Debbie lived with Sandra as a member of her household for all of 2019. b. No, because Debbie had gross income of more than $4,200 during the tax year.
Answer:
b. No, because Debbie had gross income of more than $4,200 during the tax year.
Step-by-step explanation:
Qualifying relative refers to the person those who meet the five of the requirements of the Internal revenue Service or the IRS. They are :
-- The person is not a qualifying child.
-- Individual must be a citizen of U.S., Canada or Mexico or alien resident of the USA.
-- The person should be a relative of the tax payer for a complete and has a relationship with the tax payer which is either by blood or by donation.
-- The tax payer should be supporting a higher than half of the expenses of the person.
-- Individual must have less than a gross income of 4,200 dollar in the year 2019.
Since, gross income is 18,250 dollar of Debbie and therefore she is not a qualifying relative.
Write an exponential function in the form y=ab^xy=ab x that goes through points (0, 3)(0,3) and (4, 7203)(4,7203).
Answer:
[tex]y = 3(7)^x[/tex]
Step-by-step explanation:
Given
[tex](x_1,y_1) = (0,3)[/tex]
[tex](x_2,y_2) = (4,7203)[/tex]
Required
Determine an exponential function
Substitute 0 for x and 3 for y in [tex]y=ab^x[/tex]
[tex]3 = ab^0[/tex]
[tex]3 = a*1[/tex]
[tex]3 = a[/tex]
[tex]a = 3[/tex]
Substitute 4 for x and 7203 for y in [tex]y=ab^x[/tex]
[tex]7203= ab^4[/tex]
Substitute 3 for a
[tex]7203= 3*b^4[/tex]
Divide both sides by 3
[tex]2401= b^4[/tex]
Take 4th root of both sides
[tex]\sqrt[4]{2401} = b[/tex]
[tex]7 = b[/tex]
[tex]b = 7[/tex]
Substitute 3 for a and 7 for b in [tex]y=ab^x[/tex]
[tex]y = 3(7)^x[/tex]
Describe and correct the error in solving the following rational equation , plz help!!!!!
First of all, x cannot ever equal -1 because if it does then in the original equation you'd be dividing by 0, which is not possible. anything divided by 0 is undefined.
I think the error was in the second step: x(x+1) = 2(x+1) because they didn't need to go from the first step to there. I'm assuming they multiplied both sides of the equation with (x+1) to get rid of the fraction, but since both sides have (x+1) as the denominator the (x+1) would've cancelled out instead of multiplying with the numerator.
Correction:
[tex]\frac{x}{x+1} = \frac{2}{x+1}\\(\frac{x+1}{1}) (\frac{x}{x+1}) = (\frac{2}{x+1})(\frac{x+1}{1}) \\x = 2[/tex]
as u can see, in the second step of this correction, the (x+1)s on both sides cancel out so only the numerators remain.
Hope this helps!

-2(x - 2) = -3 - 21 I need help with that question, I've been trying to solve it for hours but i cant find the answer
Answer:
x = 14
Step-by-step explanation:
you would first distribute the -2 with x - 2, which should give you -2x + 4, and you want to do the -3 - 21, which would give you -24, then subtract 4 from -2x + 4, then you should have -2x = -28, then divide it by -2, which should give you x = 14
Answer:
x = 14
Step-by-step explanation:
In this problem, we must isolate x
Given: -2(x - 2) = - 3 - 21Simplify the right side: -2(x - 2)= - 24Distribute the -2 to x and -2 (multiply): -2x + 4 = -24Subtract 4 from both sides: -2x = -28Divide both sides by -2: x = 14A garden table and a bench cost $935 combined. The garden table costs $85 more than the bench. What is the cost of the bench?

table + bench = $ 935
$85 + 2b = $935

Mr. Hayes has 11 straw bundles to use forr bedding in his horse stalls. What is the greatest number of stalls he can fill if each stall holds exactly 4 bundles
Answer:
2 stalls
Step-by-step explanation:
Mr. Hayes has 11 straw bundles to use forr bedding in his horse stalls. What is the greatest number of stalls he can fill if each stall holds exactly 4 bundles
1 stall = 4 bundles
4 bundles = 1 stall
11 bundles = x
Cross Multiply
4x = 11
x = 11/4
x = 2 3/4 stalls
The greatest number of stalls he can build is 2 stalls
