One winter day, the temperature outside was 13°F. Overnight, the temperature dropped 9°F. What is the temperature at its coldest point? Describe how you would find your answer on a number line.
Answer:
the coldest point would be 4 degrees.
Step-by-step explanation:
On a nuber line you would plot the point 13 and go back on the number line 9 units and you would get 4 degrees.
The temperature at its coldest point is 4° F.
Given that, one winter day, the temperature outside was 13°F. Overnight, the temperature dropped 9°F.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Let the temperature at its coldest point be x.
Now, x = 13 - 9
= 4° F
Therefore, the temperature at its coldest point is 4° F.

Pamela is making pizzas. She has 112 pieces of pepperoni. She uses 29 pieces of pepperoni on the first pizza. If she uses the same amount on each pizza, does she have enough pepperoni to make 4 more pizzas?
Answer:
No
Step-by-step explanation:
Number of pieces of pepperoni available with Pamela = 112
Number of pieces of pepperoni used in one pizza = 29
Now, number of pepperoni left after using 29 in one pizza = 112 - 29 = 83
Now, Pamela makes second pizza, so again 29 pieces of pepperoni area used.
Now, number of pepperoni left after using 29 in one pizza = 83 - 29 = 54
Now, Pamela makes third pizza, so again 29 pieces of pepperoni area used.
Now, number of pepperoni left after using 29 in one pizza = 54 - 29 = 25
To make the third pizza, another 29 pepperoni are required but only 25 are available.
Therefore, there is not enough pepperoni for making 4 more pizza.

Answer:
We know that angels 5 and 6 are vertical angles, and that vertical angles are equal. We also know that angles 7 is equal to angle 6, in turn meaning that angle 7 is also equal to angle 5. Now we look at angle 8. We can see that angle 8 is vertical to angle 7, meaning its also equal to angle 7. We already established before that angle 7 is equal to angle 5, so if angle 8 is equal to angle 7 which is equal to angle 5. Then angle 8 is equal to angle 5.

What is the volume of the toy top pictured below?
Answer:
The volume of the top toy is 67.1175 cubic feet
Step-by-step explanation:
The toy top is a composite figure of a cylinder and an hemisphere, the volume of the figure is therefore, the sum of the volume of the cylinder and the hemisphere
The dimensions of the cylinder are;
The height of the cylinder = 6 feet
The diameter of the cylinder, [tex]D_{cylinder}[/tex] = 1.5 feet
Therefore, the radius of the cylinder, [tex]r_{cylinder}[/tex]= 1/2 × [tex]D_{cylinder}[/tex] = 1/2 × 1.5 ft. = 0.75 ft.
The volume of the cylinder = Area of the base × Height = π × [tex]r_{cylinder}^2[/tex] × (The height of the cylinder)
Where;
π = 3.14
∴ The volume of the cylinder = 3.14 × (0.75 ft.)² × 6 ft.= 10.5975 ft.³
The dimensions of the hemisphere are;
The diameter of the hemisphere, [tex]D_{hemispher}[/tex] = 6 feet
Therefore, the radius of the hemisphere, [tex]r_{hemisphere}[/tex]= 1/2 × [tex]D_{hemispher}[/tex] = 1/2 × 6 ft. = 3 ft.
The volume of the hemisphere = 2/3×π×[tex]r_{hemisphere}^3[/tex]
∴ The volume of the hemisphere = 2/3 × 3.14 × (3 ft.)³ = 56.52 ft.³the
The volume of the top toy = The volume of the cylinder + The volume of the hemisphere
∴ The volume of the top toy = 10.5975 ft.³ + 56.52 ft.³ = 67.1175 ft.³.

A linear model is yr
Answer:
12x+36
Step-by-step explanation:
If we subtract 36 from all 4 y's we get 72, 144, 216, and 288. We divide each one by 6, 12, 18, and 24. After we divide them up, we get 12 for each one. Now we need to set the equation up, it has to be 12x because the price of just one T-shirt is $12, the x is how many T-shirts are bought. The 36 is the b-intercept of the equation, and since we write this in y=mx+b, the equation is y=12x+36.
A linear model will be 12x+36.
What is a linear model?A linear model specifies a linear relationship between a dependent variable and n independent variables.
Given that, A chess team is ordering customized T-shirts for a competition. The table shows the cost of ordering
Number of T-shirts, 6 12 18 24
If we subtract 36 from all 4 y's we get 72, 144, 216, and 288. We divide each one by 6, 12, 18, and 24. After we divide them up, we get 12 for each one. Now we need to set the equation up, it has to be 12x because the price of just one T-shirt is $12, the x is how many T-shirts are bought. The 36 is the b-intercept of the equation, and since we write this as y=mx+b, the equation is y=12x+36.

The line passing through which two points is parallel to the line x - 2y = 16?
A) -6,-1 and 2,-5
B) -4,-6 and 2,-9
C) -5,7 and 0,-3
D) -1, 5 and 3,13
E) -4,7 and -2,8
Answer:
E) -4,7 and -2,8
Step-by-step explanation:
parallel lines have same slope
x - 2y = 16
y = 1/2 x -8 slope: 1/2
E. slope = Δy / Δx = (8-7) / (-2 - -4) = 1/2
Using the slope, it is found that the line passing through points (-4,7) and (-2,8), option E, is parallel to the given line.
----------------------
The equation of a line, in slope-intercept formula, is given by:
[tex]y = mx + b[/tex]
In which m is the slope.If two lines are parallel, they have the same slope.Given two points, the slope is given by change in y divided by change in x.----------------------
The line given is:
[tex]x - 2y = 16[/tex]
In slope-intercept formula:
[tex]2y = x - 16[/tex]
[tex]y = \frac{x}{2} - 8[/tex]
----------------------
In this question, we want a line with an slope of 1/2.
At option E, the points are (-4,7) and (-2,8), thus, the slope is:
[tex]m = \frac{8 - 7}{-2 - (-4)} = \frac{1}{-2 + 4} = \frac{1}{2}[/tex]
Thus, the line passing through points (-4,7) and (-2,8), option E, is parallel to the given line.

For every 2 reeses pieces, there are 7 snickers. If there are 16 reeses pieces, how many total pieces of candy are there?
Answer:
There are 72 pieces of candy.
Step-by-step explanation:
Since there are 16 Reeses in all, we need to find out how many 2's can fit in 16. We can do that by either multiplying or dividing.
16 ÷ 2 = 8 or 8 × 2 = 16
So we have 8 groups of 2 Reeses, now we need to multiply the groups of Reeses by how many Snickers.
So:
8 × 7 = 56
Now we need to add the Snickers and the Reeses.
56 + 16 = 72
Answer:
72 candies
Step-by-step explanation:
To find the number of snickers, divide the 16 reese's pieces by two to get 8. For every two reese's pieces, there are seven snickers, so multiply that by seven to get 56. There are 56 snickers. Add the 56 snickers to the given 16 reese's pieces for 72 total pieces of candy. Hope this helped ^^
What is the solution to the system of equations?
y = 2x + 6
y= x+ 2
A. (0,0)
C. (-2,-4)
B. (-4,-2)
D. (3,6)
Answer:
B
Step-by-step explanation:
Given the 2 equations
y = 2x + 6 → (1)
y = x + 2 → (2)
Substitute y = 2x + 6 into (2)
2x + 6 = x + 2 ( subtract x from both sides )
x + 6 = 2 ( subtract 6 from both sides )
x = - 4
Substitute x = - 4 into either of the 2 equations and evaluate for y
Substituting into (2)
y = - 4 + 2 = - 2
solution is (- 4, - 2 ) → B
When we compare two fractions with the same numerator, which
statement below is true?
А
The fractions with the same
numerators are the same.
11
The fraction with the smaller
denominator is the larger fraction.
C
The fraction with the larger
denominator is the larger fraction.
D.
We cannot say which is larger or
smaller than the other.
Answer:
The fraction with the smaller denominator is the larger fraction.
Step-by-step explanation:
Let's take [tex]\frac{5}{6}[/tex] and [tex]\frac{5}{10}[/tex]. The larger the denominator, the more the number of pieces. So if you have a pizza box divided into 6 slices, and they are all the same size, compared to that same box of pizza divided into 10 slices. Each of those 10 slices will be smaller than the 6 slices. Now if you eat 5 of the 6 slices, compared to if you eat 5 of the 10 slices, which one will make you more full and you know that you have eaten a lot? Of course, it is the 5 out of 6 slices because each of those slices is bigger. So the smaller the denominator of the fraction, the larger it is (if the numerator stays the same).
