Answer:
Step-by-step explanation:
Let the section size for section 1, section 4 and section 3 = x for each of them
Let the section size for Section 2 = 2x
Total size for the three = sections = 3x + 2x = 5x
P(2) = 2x/5x = 0.4 The xs cancel
Answer: P(2) = 0.4
use substitution to determine if 0 is a solution of 5x = 5.
Answer:
No
Step-by-step explanation:
0 5(x)=5Substitution:
5(0)=5
Anything times 0 equals 0 so
does 0=5?
No
A jar contains 125 marbles. Given 2% of the marbles are green, 54% of the marbles are blue, and the rest are red, how many red marbles are in the jar?
there are 55 red marbles in the jar
Answer:
There are 55 red marbles in the jar.
Step-by-step explanation:
Green marbles = 125 x 2/100 = 2.5
Blue marbles = 125 x 54/100 = 67.5
Red marbles = 125 - 67.5 - 2.5 = 55
A ball bounces half as far as it did on the preced-
ing bounce and traveled a total distance of 12 feet
on two bounces. How far did it go on the first
bounce?
Answer:
Think proportion and ratio.
The ball bounced twice and travelled 12ft.
The first bounce is twice the distance of the second bounce so the second bounce must be equal to two of the first.
2:1 of a total 12.
You now have three parts 12/3 =4
The first bounce is 2 times this amount which is 8 ft the second bounce was 4 ft as it was only one part.
Given that f(x)=x^2 + x and g(x) = 3x + 1,
find the value f(g(4))
Answer:
110
Step-by-step explanation:
Given that [tex]f(x)=x^2 + x[/tex] and [tex]g(x) = 3x + 1[/tex] , find f(g(4))
f(g(4)) ==> you always start from the inside (g(4)).
[tex]g(x) = 3x + 1[/tex]
[tex]g(4) = 3(3) + 1[/tex]
[tex]g(4) = 9 + 1[/tex]
[tex]g(4) = 10[/tex]
[tex]f(x)=x^2 + x[/tex]
[tex]f(10)=10^2 + 10[/tex]
[tex]f(10)=100 + 10[/tex]
[tex]f(10)=110[/tex]
Final answer, 110.

Claire estimates the her brother is 4 feet tall. When they get measured at the doctor's office her brother's height is 4 feet 2 inches. What was the error, expressed in inches?
Answer: 2 is less than 5 so when she rounded she ended up with 4 feet and the doctors didn’t round
Step-by-step explanation:
I think this is correct
Explanation:
The error is the amount Clair is off by. Both figures involve "4 feet", but the actual measurement has the additional "2 inches" added on. So this is why she is off by 2 inches.

Alex’s SUV gets an average of only 15 miles per gallon. Gas costs $2.19 per gallon. Write a rule that gives the cost of a trip C when you know the number of miles d that Alex travels.
Answer:
(d miles)/(15 miles/gallon)*($2.19/gallon)
Step-by-step explanation:
Fuel efficiency = 15 miles/gallon.
Gas is $2.19/gallon.
Total cost is y.
miles is d
The equation that provides the total fuel for a trip in Alex's SUV would be:
Fuel for d miles (gallons) = (d miles)/(15 miles/gallon)
This is the total fuel required for a trip of d miles. Multiply this times the cost per gallon to find the total ciost of the trip:
(d miles)/(15 miles/gallon)*($2.19/gallon) = Total cost for a trip of d miles.

Answer:
20%
Step-by-step explanation:
It would be 20% because there is a total of 5 numbers and by which 1 is a 3 so 1/5=20%
chance for 2=60% Because there are 3 2 so 3/5=60%
chance for a 1=20%

What is 1/4 divided by -1/2?
Answer:
1/2
Step-by-step explanation:
KEEP 1/4 CHANGE the sign to multiplication FLIP 1/2 to 2/1
new equation: 1/4 x 2/1
now we can solve
we do: 1 x 2= 2
so 2 is our nominator
then we do: 4 x 1= 4
so 4 is our denominator
combine the nominator and denominator and we get
1/2 which in decimal form is 0.5
Find the lateral surface area of the triangular prism. A) 84 in2 B) 90 in2 C) 96 in2 D) 104 in2.
The lateral surface area of the provided triangular prism is 96 square inches. Option C is the correct option.
What is surface area?Surface area of any solid or the 3 dimensional body is the area of each faces by which the solid body is enclosed.
The lateral surface area of the triangular prism can be calculated with the following formula.
[tex]A_{LS}=h(a+b+c)[/tex]
Here, (a,b,c) are the bases of the rectangular faces and (h) is the common height.
The image of the triangular prism is attached below. In the given triangular prism, the common height is 8 in and bases of the rectangular faces are 5 in, 4 in and 3 in long.
To find the lateral surface area of the given triangular prism, put the values in the above formula.
[tex]A_{LS}=8(5+4+3)\\A_{LS}=8(12)\\A_{LS}=96\rm\; in^2[/tex]
Thus, the lateral surface area of the provided triangular prism is 96 square inches. Option C is the correct option.

Solve for the value of p
dont ask for ang information cuz that is literally all it says
Answer:
p = 35
Step-by-step explanation:
( 2p + 5 ) + ( 3p ) = 180
-
2p+5+3p=180
Combine 2p and 3p to get 5p.
-
5p+5=180
Subtract 5 from both sides.
-
5p=180−5
Subtract 5 from 180 to get 175.
-
5p=175
Divide both sides by 5.
p = 175\5
Divide 175 by 5 to get 35.
-
p = 35

Question 1
What value of “n” makes the equation true?
Provide evidence.
-n + 8 = 12
Answer: " n = - 4 " .
__________
Step-by-step explanation:
Given:
-n + 8 = 12 ; solve for "n" ;
Subtract "8" from each side of the equation:
-n + 8 - 8 = 12 - 8 ;
to get:
-n = 4 ;
Which is the same as:
-1n = 4 ;
Divide each side of the equation by "-1" ; to isolate "n" on one side of the equation; and to solve for "n" :
-1n / -1 = 4 / -1 ;
to get:
" n = - 4 " ; which is our answer.
_______________
Now, let's check our answer:
_______________
→ by plugging in our value obtained for "n" ; which is " - 4 " ;
_______________
-(-4) + 8 ≟ 12 ?? ;
_______________
From the "left-hand sign" of the equation:
_______________
" - (-4) = ⁺ 4 " ;
_______________
Note: The opposite of negative value; or the negative of a negative value; is equal to that very positive value.
_______________
⇒ " 4 + 8 ≟ 12 ? ;
⇒ " 12 ≟ 12 ? ; Yes!
_______________
The correct answer is: " n = - 4 " .
