Pam read 126 pages of her summer reading book in 3 hours. Zac read a 180 pages of his sunday reading book in 4 hours. If they continue to read at the same speeds, will they both finish the 215 page book after 5 total hours of reading. explain
Answer:
yes they both will because in four they both read more then half the book and one more hours should let them finshed the book
Step-by-step explanation:
Answer:
Zack is able to, but Pam cannot.
Step-by-step explanation:
Number of pages Pam read in 5 hours = 5 x 42 = 210 pages
Number of pages Zack read in 5 hours = 5 x 45 = 225 pages

Answer/Step-by-step explanation:
The equation of the line that passes through the two points would be correct if each point, when substituted into the equation, satisfy the equation.
This is what I mean:
Given the equation of the line, y = 2x - 5, and the two points (-2, -9) and (3, 1):
For the first point, substitute x = -2, and y = -9 into y = 2x - 5.
Thus:
-9 = 2(-2) - 5
-9 = -4 - 5
-9 = -9 (this is true). It means the line runs through the point (-2, -9)
For the second point, substitute x = 3, and y = 1 into y = 2x - 5
This:
1 = 2(3) - 5
1 = 6 - 5
1 = 1 (this is true). This also means the point, (3, 1) is also a point that the equation runs across.
Enter the midpoint of the segment whose endpoints are (2,9) and (-8, 14).

Find the simple interest.
Principal:$6000
Interest Rates: 5%
Time: 6 months
Is it $1500 or $150?
Answer:
Given,
P = ₹5,000
R = 5%
T = 6 months
= 1/2 years
S.I = P×R×T/100
= 5,000 × 5 / 2×100
= 250 / 2
= ₹125
Step-by-step explanation:
The simple interest of principal of $ 6000 at an interest rate of 5% for a period of 6 months is $ 150
What is Simple Interest?
Simple interest is a method of calculating interest that ignores the impact of compounding. While interest frequently compounds throughout the course of a loan's set periods, simple interest does not. Simple interest is calculated by multiplying the principal amount by the interest rate, times the number of periods.
Simple Interest = ( Principal Amount x Rate x Time Period ) / 100
Given data ,
Let the total amount be Principal P = $ 6000
Let the interest rate be R = 5 %
Let the number of periods be T = 6 months
So , the value of T = 1/2
Now , the simple interest is given by the formula
Simple Interest = ( Principal Amount x Rate x Time Period ) / 100
Substituting the values in the equation , we get
Simple Interest = ( 6000 x 5 x ( 1 / 2 ) ) / 100
Simple Interest = ( 60 x 5 ) / 2
Simple Interest = $ 150
Therefore , the value of simple interest is $ 150
Hence , The simple interest of principal of $ 6000 at an interest rate of 5% for a period of 6 months is $ 150

katie collets stamp she has stamps from canada, United Staes,ands Rest of the world in a ratio of 1:1.2:1.5 she has 135 stamps from rest of the world
Answer:
90 stamps from Canada, 108 stamps from the United States, and 135 stamps from the Rest of the World
Step-by-step explanation:
Since this is a problem of proportion we can use the Rule of three to solve this. We do this by multiplying the diagonal available values and dividing by the third value in order to get the missing variable, which in this case would be the number of stamps in the other country. Like so...
1.5 <=====> 135 stamps
1.2 <=====> x stamps (United States)
(1.2 * 135) / 1.5 = 108 stamps (United States)
1.5 <=====> 135 stamps
1 <=====> x stamps (Canada)
(1 * 135) / 1.5 = 90 stamps (Canada)
Finally, we can see that Katie had 90 stamps from Canada, 108 stamps from the United States, and 135 stamps from the Rest of the World. All creating a ratio or 1:1.2:1.5
PLEASE PLEASE I SUCK AT MATH AND ITS ALL DUE FRIDAY PLEASE 10 piont !!! Select all the correct systems of equations.
Which systems of equations have infinite solutions?
2x + 5y = 31
6x - y = 13
2x + y = 10
-6x = 3y + 7
y = 14 - 2x
6x + 3y = 42
y = 13 - 2x
4x - 3y = -19
2x + y = 14
x = 13-2y
2x + y = 17
-6x = 3y - 51
Reset
Next
Answer:
2x + y = 17
-6x = 3y - 51
Step-by-step explanation:
You get an infinite number of solutions when two equations are really just the same. This means you can convert one into the other simply by multiplying one to get the other.
In the above answer, if you multiply the above by -3 you get:
-6x -3y = -51
which is of course -6x = 3y - 51
So that is an example of a pair that has infinite solutions.
To find all of them, you'd carefully have to compare each 2 and see if there is a multiplier to convert one into the other. You can do that!

How much would you need to deposit in an account now in order to have $2000 in the account in 10 years? Assume the account earns 2% interest compounded monthly
Step-by-step explanation:
A(t) = amount in t years
P = Principal (original investment)
r = annual interest rate (in decimal form)
n = number of times that interest is compounded each year
A(t) = P(1 + r/n)nt
Substitute in the given values: 2000 = P(1 + 0.04/12)12(10)
2000 = P(1.490832682)
P = $1341.53

The base of a cone shaped glass is 12 inches and it is 18 inches tall. You
fill the glass with soda pop to the top of the glass. What is the volume of
soda pop
Answer:
Step-by-step expla
To find the volume of a cone, use the equation: V = 1/3Bh.
In this equation, V is the volume, B is the base, and h is the height.
We are given that the base is 12 inches, and the height is 18 inches. With those necessary values, we can substitute those values, and calculate it.
V = 1/3(12)(18)
V = 4(18)
V = 72.0
Therefore, the volume of this glass is 72.0 cubic inches.

C. 14
d. 16
Answer:
Fill in the blank with 14
Step-by-step explanation:
Given
The attached table
Required
Fill in the gap
Since, the table represents a linear function.
The first step is to calculate the slope of the table
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
Where
[tex](x_1,y_1) = (1,2)[/tex]
[tex](x_2,y_2) = (2,6)[/tex]
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{6 - 2}{2 - 1}[/tex]
[tex]m = \frac{4}{1}[/tex]
[tex]m=4[/tex]
The equation of the table is calculated next as:
[tex]y - y_1 = m(x - x_1)[/tex]
This becomes
[tex]y - 2 = 4(x - 1)[/tex]
[tex]y - 2 = 4x - 4[/tex]
Solve for y
[tex]y = 4x - 4+2[/tex]
[tex]y = 4x -2[/tex]
To fill in the blank;
The value of x is 4
So, substitute 4 for x in [tex]y = 4x -2[/tex]
[tex]y = 4 * 4 - 2[/tex]
[tex]y = 16 - 2[/tex]
[tex]y = 14[/tex]

Step-by-step explanation:
1/2y = 4
x - 1/2y = 2
First solve for y in the first equation.
1/2y = 4 Divide both sides by 1/2
y = 8
NOw substitute the value of y into the second equation and solve for x.
