In 4/5 hours, Manuel reads 3/4 chapters. What is the unit rate in chapters per hour?
Manuel reads 3/4 chapter in 4/5 hours.
Rate = Chapter / Hours
Rate = (3/4) / ( 4/5)
Rate = 0.75 / 0.80
Rate = 0.9375
So, Manuel reads the chapter with rate 0.9375 chapters/hour.

2x + 2 y = -2
3x - 2y = 12
Answer:
x=2 and y=-6 aka. (2,-6) which is the point of intersection
Step-by-step explanation:
Use elimination to cancel out y by adding the equations:
5x=10
x=2
Plug x=2 into one of the equations and find y:
2(5)+2y=-2
10+2y=-2
2y=-12
y=-6
Therefore, x=2 and y=-6

a triangle with area 28 square inches has a height that is twi less than four times the base. find the base and the height if the tringle?
Answer:
b = 4 inches and h = 14 inches
Step-by-step explanation:
Given that,
The area of a triangle, A = 28 sq inches
Height is twice less than 4 times the base.
H = 4b-2, b is base
We know that,
The area of a triangle is given by :
[tex]A=\dfrac{1}{2}bh\\\\28=\dfrac{1}{2}\times b\times (4b-2)\\\\56=4b^2-2b\\\\28=2b^2-b\\\\b=4\ inches,-3.5\ inches[/tex]
Base = 4 inches
Height = 4(4)-2
= 14 inches
Hence, this is the required solution.

Verify & mention the below given property a*(+)=*+*of rational numbers by taking a= 1:3, b= 1:5 c= -2:3
To Prove :
a×(b+c) = a×b + a×c
Solution :
Solving L.H.S. we get :
[tex]a(b+c ) = \dfrac{1}{3}( \dfrac{1}{5}-\dfrac{2}{3})\\\\= -\dfrac{7}{45}[/tex]
Solving R.H.S. we get :
[tex]a\times b + a\times c = \dfrac{1}{3}\times \dfrac{1}{5} + \dfrac{1}{3}\times (-\dfrac{2}{3})\\\\= -\dfrac{7}{45}[/tex]
Since, L.H.S = R.H.S
Therefore, the given equation is correct.
use the rules for long division to divide 724 by 11
Answer:
65 r 9
Step-by-step explanation:
First we see what 7 divided by 11 is, we know that it is 0 so we put it in the top as our first number then we subtract 0 from 7 which is 7, then we bring down the 2 to make our next number 72, now we see if 11 can go into 72 and we know that it can by 6, we put our six on the top and then multiply it by 11 to get 66, we subtract our 66 from 72 to get 6, we bring down the 4 to make 64 and divide it by 11 to get 5 which we put on the top, then multiply 5 by 11 to get 55, subtract 55 by 64 to get 9 and because now there's no more numbers in the sum, 9 is our remainder.

Hayden and Brianna received a mortgage in the amount of $164,320 for a condominium that cost $198,450. The documentary stamp tax fee for mortgages in their state is $0.35 per $100 or portion thereof. How much did Hayden and Brianna pay for the documentary stamp tax? (2 points)
Answer:
the answer is 575.12
Step-by-step explanation:
since the mortgage amount is $164320, you divide that by 100 because it is $100 per $.35.
lastly, you multiply it by .35
you should have something like this: 164320/100x0.35
which equals 575.12.

SOCCER Alice kicks a soccer ball towards a wall. The ball is deflected off the wall at an angle of 40°,
and it travels 6 meters. How far is the soccer ball from the wall when it stops rolling?
Answer:
The ball is 3.86 meters from the wall when it stops rolling.
Step-by-step explanation:
Representation of the situation:
This situation can be represented by a right triangle:
The hypotenuse is the distance the ball traveled, of 6 meters.
The distance from the wall is the side opposite to the angle of 40º.
We have that:
Sine of an angle is the length of the opposite side divided by the hypotenuse. So, in this situation.
Sine of 40 degrees = Distance from the wall/6
Sine of 40 degrees is of 0.64278760968.
Distance = 6*0.64278760968 = 3.86.
The ball is 3.86 meters from the wall when it stops rolling.

A. 20 is an even number
B. 21 is positive number
C. x is an even number
D. 21 is an even number
Answer:
C. x is an even number
Step-by-step explanation:
The open statement is x is an even number. The correct option is C.
What is an open statement?A statement (as in mathematics) that contains at least one blank or unknown and that becomes true or false when the blank or unknown is filled in or a quantity is substituted for the unknown. The sentences "n + 5 = 3" and "it is divisible by 6" are both open sentences.
here te open statement is given as x is an even number because the statement says that there is an unknown number which is even in nature. So there is a blank for the number the number can be anything from all the even numbers.

Determine the nature of the solution(s) of
5w2 – 2w= -4
A- one real, rational solution
B- two real, irrational solutions
C- two imaginary solutions
D- two real, rational solutions
Answer:
Step-by-step explanation:
This is a quadratic equation. We'll find the discriminant, but must first rewrite this equation in standard form:
5w2 – 2w + 4 = -4 + 4, or 5w^2 - 2w + 4 = 0
The coefficients of the w terms are {5, -2, 4}
and so the discriminant b^2 - 4ac is 4 - 4(5)(20) = -396
Because the discriminant is negative, we know that there will be two unequal, complex solutions.
A farmer wants to divide his 2700 km2 of land into two separate pastures for his new horses by building a fence that will enclose both pastures. He wants one pasture to be twice the size as the other. What should the dimensions of the larger pasture be if he wants to use the least amount of fencing?
Answer:
Step-by-step explanation:
just a guess, it seems like you are asked about only dimensions of the big one, isnt that just 2/3 of 2700 km2. that is 1800km2 which = 60 km x 20km.

answer:
12.5%
explain:
16 seats= 6.25% for each seat
4/16=25%
the chances of it happening again is 12.5%
The probability that you are assigned to a desk in the front row exactly twice is 12.5%.
What is probability?Probability is defined as the ratio of the number of favourable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.
Probability = Number of favourable outcomes / Number of sample
Given that the desks in a classroom are organized into four rows of four columns. each day the teacher randomly assigns you to a desk. you may be assigned to the same desk more than once. over the course of 5 days,
The probability will be calculated as,
16 seats = 6.25% for each seat
4/16=25%
The chances of it happening again are 12.5%
Therefore, the probability that you are assigned to a desk in the front row exactly twice is 12.5%.
