Answer:
1st number = 4
2nd number = -1
Step-by-step explanation:
Let n = 1st number
Let m = 2nd number
2n + 4m = 4
n - m = 5
Substitu method, let n = 5 + m
2(5+m) + 4m = 4
10 + 2m + 4m = 4
6m = -6
m = -1
find n:
n - (-1) = 5
n + 1 = 5
n = 4

Answer:
[tex]B = \pi (3\frac{1}{2})^2[/tex]
Step-by-step explanation:
Given
[tex]D = 7\ in[/tex]
[tex]H = 2\frac{3}{4}\ in[/tex]
See attachment for question and options
Required
Which best describe the base area of the pan
The base area (B) is calculated using:
[tex]B = \pi r^2[/tex]
Where
[tex]r = \frac{1}{2}D[/tex]
So, we have:
[tex]r = \frac{1}{2}*7[/tex]
[tex]r = \frac{7}{2}[/tex]
[tex]r = 3\frac{1}{2}[/tex]
Substitute [tex]r = 3\frac{1}{2}[/tex] in [tex]B = \pi r^2[/tex]
[tex]B = \pi (3\frac{1}{2})^2[/tex]

In the diagram below, it is given that point Ris the midpoint of PQ. Which of the following can be concluded
based on this given?
Answer:
Sheesh good luck
Step-by-step explanation:
.........
Answer:
3
Step-by-step explanation:
MN is not equal to NR, because MN is too long
It doesn't tell us R is the midpoint of MN, so for all we know MR and RN are completely different measurements.
PR and QR must be equivalent if R is the midpoint of the two.

Answer:
Only the first point lies on the line and thus, Anders is incorrect
Step-by-step explanation:
Here, we want to show that Anders is incorrect
we simply substitute the values of his coordinates into the equation of the line
for (10,420)
we have;
420 = 40(10) + 20
420 = 420
This is right
We now test the second given point;
-420 = 40(-10) + 20
-420 = -400 + 20
-420 is not -380

Brain has two rectangular sheets of paper.
-The length of the larger sheet is 1 1/2 times the length of the smaller sheet.
-The width of the larger sheet is 1 3/5 times the width of the smaller sheet.
By what factor is the area of the larger sheet greater than the area of the smaller sheet?
Answer:
2.4
Step-by-step explanation:
Smaller sheet length = 10u
Smaller sheet width = 10u
Smaller sheet area = 10u * 10u = 100u^2
Larger sheet length = 1.5 * 10u = 15u
Larger sheet width = 1.6 * 10u = 16u
Larger sheet area = 16u * 15u = 240u^2
240u^2 / 100u^2 = 2.4
The factor when the area of the larger sheet greater than the area of the smaller sheet should be considered as the 2.4.
Calculation of the factor:Since
Smaller sheet length = 10u
Smaller sheet width = 10u
Now
Smaller sheet area = 10u (10u) = [tex]100u^2[/tex]
And,
Larger sheet length = 1.5 ( 10u) = 15u
And,
Larger sheet width = 1.6 (10u) = 16u
So,
Larger sheet area = 16u (15u) = [tex]240u^2[/tex]
Now
[tex]= 240u^2 \div 100u^2[/tex]
= 2.4
hence, The factor when the area of the larger sheet greater than the area of the smaller sheet should be considered as the 2.4.

MODELING REAL LIFE A green roof is like a traditional roof but covered with plants. Plants used for a green roof cost $0.75 per square foot. The roof shown is 40 feet long. How much does it cost to cover both sides of the roof?
Answer:
$1200
Step-by-step explanation:
Let the roof be square shaped
Area of the roof = L²
L is the side length of the roof
Given
L = 40ft
Area of the roof = 40²
Area of the roof = 1600ft²
If plants used for a green roof cost $0.75 per square foot, this means
1 ft² = $0.75
Let the cost needed to cover both sides of the roof be y, hence;
1600ft² = y
Divide both expressions
1/1600 = 0.75/y
y × 1 = 0.75×1600.
y = 0.75×1600
y = 1200
Hence it will cost $1200 to cover both sides of the roof

Answer:
math book
Step-by-step explanation:
Write a function rule that gives the total cost c(p) of p pounds of sugar if each pound costs $0.59.
A. c(p) = p + 0.59
B. c(p) = 59p
C. c(p) = p/0.59
D. c(p) = 0.59p
Answer:
D. c(p) = 0.59p
Step-by-step explanation:
The total cost, c(p), to purchase sugar is equal to the product of the pound cost equal to $0.59 and the number of pounds of sugar, p. Thus, the answer to this item is C(p)=0.59p
The total cost, c(p), to purchase sugar is equal to the product of the pound cost equal to $0.59 and the number of pounds of sugar, p. Thus, the answer to this item is,
c(p) = ($0.59)p
We multiply the number of pounds of sugar, p, time the cost per pound ,.59, to get the total cost
c(p) = .59*p
