Jack read 20 pages of a book in 60 minutes. How many pages can he read in 75 minutes at the same rate? Write a proportional equation. Please help me answer this equation!!
Answer:
25 pages
Step-by-step explanation:
Create a proportion:
[tex]\frac{pages}{minutes}[/tex] = [tex]\frac{20}{60}[/tex] = [tex]\frac{x}{75}[/tex]
Cross multiply and solve for x, the number of pages in 75 minutes:
60x = 1500
x = 25
So, he can read 25 pages in 75 minutes at the same rate

What is the product of -8 and 5? A. 40 B. -40 C. 13 D. -3
Answer:b-40
Step-by-step explanation:
Sue deposited $1,500 into two different accounts. - She deposited $600 into an account that pays 7.5% simple interest. - She deposited $900 into an account that pays 6% compounded annually. If Sue does not deposit additional money into the accounts and she doesn't withdraw any money from the accounts, which is closest to the total balance she will have in the two accounts at the end of 5 years
The required total balance at the end of the 5 years is given as $1995.
What is simple interest?Simple interest is a quick and simple formula for figuring out how much interest will be charged on a loan.
here,
Sue deposited $1,500 into two different accounts. - She deposited $600 into an account that pays 7.5% simple interest. - She deposited $900 into an account that pays 6% compounded annually.
Investment 1,
Amount = P(1 + rt)
Amount = 600(1 + 0.075×5)
Amount = $825
Investment 2,
Amount = P(1 + rt)
Amount = 900(1 + 0.06×5)
Amount = $1170
Total balance = 825 + 1170
Total balance = $1995
Thus, the required total balance at the end of the 5 years is given as $1995.

5x +2y=22
4x+y=17
In the system of equations above, what
is the value of x+y?
A. 5 B. 4 C. 3 D. 2
Answer:
A: 5
Step-by-step explanation:
4x + y = 17 --> y = 17 - 4x
5x + 2y = 22
<=> 5x + 2 . (17 - 4x) = 22
<=> 5x - 8x + 34 = 22
<=> 34 - 3x = 22
<=> 3x = 34 - 22 = 12
<=> x = 4
y = 17 - 4x = 17 - 4 . 4 = 17 - 16 = 1
So, x + y = 4 + 1 = 5

URGENT!! I have been trying to ask this question for a while but I keep getting fake answers: Find an equation in standard form for a parabolic function that goes through the points (1,-12) (3,16) and has a stretch factor of 2
Answer:
Step-by-step explanation:
y=a(x-h)^2+k
-12=a(1-h)^2+k
16=a(3-h)^2+k
subtract
a(3-h)^2-a(1-h)^2=28
a[(3-h)^2-(1-h)^2]=28
a=2
2[(3-h)^2-(1-h)^2]=28
(3-h)^2-(1-h)^2=14
9+h^2-6h-(1+h^2-2h)=14
9+h^2-6h-1-h^2+2h=14
-4h+8=14
-4h=6
h=-3/2
16=2(3+3/2)^2+k
16=2×81/4+k
k=16-81/2=-49/2
so y=2(x+3/2)²-49/2
Answer: y=a(x-h)^2+k
-12=a(1-h)^2+k
16=a(3-h)^2+k
subtract
a(3-h)^2-a(1-h)^2=28
a[(3-h)^2-(1-h)^2]=28
a=2
2[(3-h)^2-(1-h)^2]=28
(3-h)^2-(1-h)^2=14
9+h^2-6h-(1+h^2-2h)=14
9+h^2-6h-1-h^2+2h=14
-4h+8=14
-4h=6
h=-3/2
16=2(3+3/2)^2+k
16=2×81/4+k
k=16-81/2=-49/2

Answer:
C. 1.404
Step-by-step explanation:
The 1000ths place is the 1 in 0.01
The 100ths place is the 1 in 0.001
A = 0.881
The number in the 1000ths place is 1
The number in the 100ths place is 8
1/8 is not 1/10
B = 0.722
The number in the 1000ths place is 2
The number in the 100ths place is 2
2/2 is not 1/10
C = 1.404
The number in the 1000ths place is 4
The number in the 100ths place is 0
BUT the numbe rin the 100ths place could also be written as 40, where the 4 from the 40 has moved up a place to 10th
in which case, 4/40 = 1/10

Answer: The answer is D
Step-by-step explanation: First you distribute the 2 by x and 2 so you get 2x + 4 then you distribute -3 by x and -1 so you get -3x + 3 then you add up the two equations then yo get -x + 7 = 9 then you subtract the 7 on both sides so you get x = -2
Which ratios are equivalent to 10:16? Check all that apply. 30 to 48 25:35 StartFraction 40 Over 64 EndFraction 8:32 5 to 15
Answer:
30 to 48, 40/64
Step-by-step explanation:
Which ratios are equivalent to 10:16, and they gave us 30 to 48, 25:35, 40/64, 8/32 and 5 to 15.
For 30 to 48, we can mulitply the 10:16 by 3 to give us 30:48, so it is equal.
For 25:35, we simplify it to 5:7, while 10:16 is 5:8, so they are not equal.
For 40/64, we can take 10:16 and multiply them by 4, getting the same number. Therefore, it is equal.
For 8/32, we can simplify it down to 1/4, while 10:16 simplifies down to 5:8, it is not equal.
Lastly, for 5 to 15, w can simplify that to 1/3, and get 5:8 for 10:16, so it won't be equal.

What is a pre-image??? SaberXTooth bro answer me!!!
Answer:
Step-by-step explanation:Much is usually anticipated about the fierce and decidedly bloody clashes between Wolverine and Victor Creed, the man known as Sabretooth, even though these men are arguably two sides of the same coin. Each of them has deadly claws that rend and draw blood; each has a generous amount of fear and intimidation working for them; each has a healing factor that prevents them from being mortally wounded (eventually reaching preposterous levels of effectiveness); and each has killed and will kill if the situation calls for it. Yet there are differences, as well: Logan's skeleton, as well as his claws, are made of the unbreakable metal known as adamantium; and while there have often been instances where he's been shown to be merciless, he's not nearly as sadistic as Creed, who will not hesitate to kill even when there is no reason for it. Perhaps the difference that keeps us engaged, however, is the fact

Pls help me!! ASAP I WILL GIVE BRAINLIEST Brandon's bread recipe calls for milk powder, sugar, and flour in a ratio of 2:3:15, respectively. How many pounds of each does Brandon need if the three ingredients together weigh 2 lb?
Answer:
0.2 pounds of milk
0.3 pounds of sugar
1.5 pounds of flour
Step-by-step explanation:
If we have the ratio [tex]2:3:15[/tex], then we know that all of these ingredients together will be [tex]15+3+2=20[/tex]. If we want the whole thing to weight 2 pounds, then the total weight of everything else will be [tex]20\div2=10[/tex] percent of the original.
So,
[tex]2\cdot0.1=0.2\\\\3\cdot0.1=0.3\\\\15\cdot0.1=1.5[/tex]
We can confirm this is correct because [tex]1.5+0.3+0.2=2[/tex].
Hope this helped!
Step-by-step explanation:
Simple formula [tex]\frac{item ratio}{total ratio}[/tex]×total amount
milk powder; ×2= 0.2 lb
sugar; [tex]\frac{3}{20}[/tex]×2= 0.3 lb
flour; [tex]\frac{15}{20}[/tex]×2= 1.5 lb
To check you can add them up :)

A sample of 257 adults is selected. The adults are classified according to voter registration status ("registered" or "not registered"). They are also classified according to preferred source of current events information ("television", "newspapers", "radio", or "internet sites"). The results are given in the contingency table below. What is the relative frequency of adults in the sample who are not registered to vote? Round your answer to two decimal places.
The relative frequency of adults in the sample who are not registered to vote is 0.47.
What is the relative frequency?Relative frequency is a statistical concept that refers to the proportion or percentage of observations or events in a given sample or population that fall into a particular category or have a particular characteristic.
We have,
To find the relative frequency of adults in the sample who are not registered to vote, we need to sum up the number of adults who are not registered:
22 + 39 + 21 + 39 = 121 and divide it by the total sample size which is 257.
Relative frequency of adults who are not registered to vote
= (number of adults who are not registered) / (total sample size)
Relative frequency of adults who are not registered to vote.
= 121/257
Relative frequency of adults who are not registered to vote
= 0.47 (rounded to two decimal places)
Therefore,
The relative frequency of adults in the sample who are not registered to vote is 0.47.
