At the end of a snow storm, Gavin saw there was a lot of snow on his front lawn. The temperature increased and the snow began to melt at a steady rate. There was a depth of 10 inches of snow on the lawn when the storm ended and then it started melting at a rate of 0.5 inches per hour
Answer: 20 hr
Step-by-step explanation:
Given
The depth of accumulated snow is [tex]d=10\ in.[/tex]
Snow is melting at the rate of [tex]r=0.5\ \text{in. per hour}[/tex]
Time taken for complete melting of snow is
[tex]\Rightarrow t=\frac{d}{r}\\\\\Rightarrow t=\frac{10}{0.5}=20\ hr[/tex]
Tina is cutting construction paper into rectangles for a project. She needs to cut one rectangle that is 15 inches × 12 1/3 inches. She needs to cut another rectangle that is 10 1/4 inches by 10 1/3 inches. How many total square inches of construction paper does Tina need for her project?
Answer:
Step-by-step explanation:
Remark
This is an "in theory" type of question. She's going to actually need a little more.
Area 1
L = 15
W = 12 1/3
Area = L*W
Area = 15 * 12 1/3 I wonder if you know what the distributive property is. I'll try it. If you don't understand, leave a remark
Area = 15 * (12 + 1/3) Multiply both parts by 15
Area = 15*12 + 1/3 * 15
Area = 180 + 5
Area = 185 square inches.
Area 2.
This is a little harder because their are
2 fractions.
The easy way to do this is change to decimals
L = 10 1/3 = 10.33333333
W = 10 1/4 = 10.25
Area = 10.3333333 * 10.25
Area = 105.92 Add
Total Area
The total area = 290.92

write a quadratic equation with a double root of -5
Answer:
x^2 =5
Step-by-step explanation:
Answer:
x² + 10x + 25 = 0
Step-by-step explanation:
Given that x = - 5 is a root then (x + 5) is a factor
Since it is a double root then (x + 5)² so equation is
(x + 5)² = 0 ← expand factor using FOIL
x² + 10x + 25 = 0
Which equation represents a line which is parallel to x=0?
y=5
x=4
x=1/4y
x=−4y
Answer:Answer is A
Step-by-step explanation:
Correct option is
A
6x+2y=15
Given line is y=−3x+4
This is slope intercept form of a line where slope of line is −3.
Since, two lines are parallel When their slopes are equal.
Slope of line is 6x+2y=15
⇒2y=−6x+15
⇒y=−3x+
2
15
is equal to −3
Option A is correct.

The official all-time high temperature in Osoyoos, B.C., was 43°C in July 1998. The official all-time low temperature was –21°C in February 1996. What is the difference between the two temperatures? Please show all your work.
Answer: 64°C
Step-by-step explanation:
Official all-time high temperature = 43°C
Official all-time low temperature = –21°C
The difference between the two temperatures will be calculated by subtracting the low temperature from the high temperature. This will be:
= 43°C - (-21°C)
= 43°C + 21°C
= 64°C

A dilation maps (4, 6) to (2, 3). Under the same dilation, (-1, 3) would be mapped to _____. (-1/2, 3/2) (-3, 0) (-2, 6)
Answer:
(-1/2, 3/2).
Step-by-step explanation:
A dilation maps (4, 6) to (2, 3).
4/2 = 2, 6/3 = 2
It means that each coordinate is divided by 2.
(-1, 3) would be mapped to
Dividing by 2: (-1/2, 3/2) is the correct answer
Given A(8,3), B(4,8), C(4,4) and D(8,-1) find the slope of AB
Answer:
Step-by-step explanation:
Slope: [tex]\frac{y_2-y_1}{x_2-x_1}[/tex] when the given points are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]
Plug in A(8,3) and B(4,8)
[tex]=\frac{8-3}{4-8} \\=\frac{5}{-4}\\=-\frac{5}{4}[/tex]
Therefore, the slope of AB is [tex]-\frac{5}{4}[/tex].

Solve this system of equations by using the elimination method -2x-2y=-6, 3x+4y=8
Step-by-step explanation:
- 2x-2y=-6
3x+4y=8
multiply equation (1) by 3 and equation (2) by 2
- 6x-6y=18
6x+8y=16
Add
2y=34
y= 34÷2
y=17
substitute 17 for y in equation (2)
3x+4y=8
3x+4(17)=8
3x+68=8
3x=8-68
3x=-60
x=-60÷3
x=-20
x=-20,y=17
