If A train travels 220 miles in 4 hours. Then train's speed in feet per minute is 4840.
What is speed?Speed is the time rate at which an object is moving along a path,
To work out speed you use the speed, distance and time formula:
This is speed = distance/time.
Let us convert 220 miles into feet,
1 mile=5280 ft.
So 220 miles
=220×5280
=1161600 ft
Then we convert 4 hours into minuets
4 * 60 = 240mins
now plug in the formula with time and distance .
1161600ft/240mins = 4840 ft/min
Hence 4840 ft/min is the speed of train in feet per minute.

Which transformation rule maps triangle ABC onto triangle DEF ?
(x−7, y+3)
(x+3, y−7)
(x+7, y−3)
(x−3, y+7)
Answer: The correct option is (C) (x+7, y−3) .
Step-by-step explanation: We are given to select the correct transformation rule that maps triangle ABC onto triangle DEF.
From the graph, we note that
the co-ordinates of the vertices of triangle ABC are A(-8, 6), B(-3, 6) and C(-7, 4).
And, the co-ordinates of the vertices of triangle DEF are D(-1, 3), E(4, 3) and F(0, 1).
The transformations from the vertices of triangle ABC to the vertices of triangle DEF are
A(-8, 6) → D(-1, 3) = D(-8+7, 6-3),
B(-3, 6) → E(4, 3) = E(-3+7, 6-3)
and
C(-7, 4) → F(0, 1) = F(-7+7, 4-3).
Therefore, the required transformation rule is given by
(x, y) → (x+7, y-3).
Thus, (C) is the correct option.

What is the perimeter of triangle PQR? Show your work.
Answer:
PQR= 17 ft
Step-by-step explanation:
1. PQ ≅ ST = 4 ft (Given)
2. ∠PQR ≅ ∠STU (Given)
3. QR ≅ TU = 6 ft (Given)
Which makes the two triangles congruent by SAS postulate.
Now, from CPCTE, PR = SU
3y-2=y+4
Solve for y and simplify
Subtract Y from both sides.
Add 2 to both sides
3y-y=4+2
Add
2y=6
Divide both sides by 2
Y=3
Now, side PR is given by plugging in 3 for Y. PR = 3(3) - 2 = 9 - 2 = 7 ft. The perimeter of a triangle PQR is the sum of all of its sides. Perimeter = PQ + QR + PR = (4 + 6 + 7) ft = 17 ft. The perimeter of triangle PQR is 17 ft.

Eliza and Jamie are making cupcakes for a bake sale at school. Eliza needs 2one third c of flour for her recipe and Jamie needs 1three-fourths c for her recipe. They have 4 c of flour. Do they have enough flour for both recipes? Explain.
HELP!!!
Answer:
Givens:
They have 4c of flour.Eliza needs 2 1/3 c of flour.Jaime needs 1 3/4 c of flour.To know if the have enough flour, we just need to sum both amounts, but before that, we need to transform all mixed numbers into fractions
[tex]2\frac{1}{3}= \frac{7}{3}[/tex]
[tex]1\frac{3}{4}=\frac{7}{4}[/tex]
Now, we sum
[tex]\frac{7}{3}+\frac{7}{4}=\frac{28+21}{12}=\frac{49}{12}\approx 4.08[/tex]
Therefore, the just have enough flour to do their recipes, because they need 4.08 c of flour approximately, and they have 4 c of flour.
Final answer:
Eliza and Jamie do not have enough flour for both of their recipes for a school bake sale. After adding the required amounts, they are short by 1/12 cup since they need 4 1/12 cups and have only 4 cups of flour.
Explanation:
Eliza needs 2 1/3 cups of flour for her recipe and Jamie needs 1 3/4 cups for hers. To determine if they have enough flour, we must add these two amounts together:
Convert 2 1/3 to an improper fraction: 2 1/3 = (2 × 3) + 1 = 6 + 1 = 7/3 cupsConvert 1 3/4 to an improper fraction: 1 3/4 = (1 × 4) + 3 = 4 + 3 = 7/4 cupsAdd the two amounts of flour: 7/3 c + 7/4 c = (7 × 4) + (7 × 3) / (3 × 4) = 28/12 + 21/12 = 49/12 cupsConvert 49/12 cups to cups: 49/12 = 4 with a remainder of 1/12, which means they need 4 1/12 cups of flour in total.Since they have exactly 4 cups of flour, Eliza and Jamie do not have enough flour; they are short by 1/12 cup for both recipes combined.
When considering the total amount of flour needed for a recipe, it's important to make sure the sum does not exceed the available amount. In Eliza and Jamie's case, they will need to acquire more flour to meet the requirements of both their recipes for the bake sale.

1. An enclosed wooden crate is 4 feet tall, 8 feet long, and 6 feet wide. What is the total area of the top, bottom, front, back, and the left and right sides of the crate?
The total area of the top, bottom, front, back, and both sides of the crate is 208 square feet. This is calculated by finding the area of each pair of identical surfaces and summing these areas.
Explanation:To calculate the total area of the top, bottom, front, back, and the left and right sides of a crate that is 4 feet tall, 8 feet long, and 6 feet wide, we need to find the area of each of these surfaces and sum them up. There are three pairs of identical surfaces on a rectangular crate.
The top and bottom surfaces each have an area of 8 feet (length) × 6 feet (width) = 48 square feet. So, for both the top and bottom together, the area is 48 square feet × 2 = 96 square feet.The front and back surfaces each have an area of 8 feet (length) × 4 feet (height) = 32 square feet. Therefore, the total area for both the front and back is 32 square feet × 2 = 64 square feet.The left and right sides each have an area of 6 feet (width) × 4 feet (height) = 24 square feet. So, the total area for both sides comes to 24 square feet × 2 = 48 square feet.To find the total area of all these surfaces combined, we add these amounts together: 96 square feet + 64 square feet + 48 square feet = 208 square feet.

Suppose point J has coordinate of -2 and JK=4. Then what is the possible coordinate(s) for K? 4 2 or -4 -4 2 or -6
Given that point J is at -2 and the distance between J and K is 4, the possible coordinates for K are -6 (if you count 4 steps to the left) or 2 (if counted to the right on the number line).
Explanation:The given information tells us that point J has a coordinate of -2 and the distance JK equals 4. In a number line, distances can be counted to the left (negative direction) or to the right (positive direction). Therefore, point J will be 4 points to the left or right of, which means the coordinates for K could be -2-4 = -6 or -2+4 = 2.

How to solve a system of equations using elimination
To solve a system of equations by addition, also called elimination, the goal is to cancel out one of the variables by adding the equations together. However, in some cases, you will need to multiply one or both of the equations by a number in order to create a scenario where one of the variables will cancel out when the equations are added together. As long as you cancel a variable out, you will be able to add the equations together and solve for the variable. If you find one variable, you can find the other one easily.
