Amber ran a 25 kilometer road race in 3 hours. She ran at the same speed and covered the same distance each hour. Draw a visual model to find the distance Amber ran each hour. Between which two whole numbers does the she ran each our lie
Answer:
Amber ran 8,333 kilometers during each hour, and the equation to determine that amount is 25/3 = X.
Step-by-step explanation:
Given that Amber ran a 25 kilometer road race in 3 hours, and she ran at the same speed and covered the same distance each hour, to draw a visual model to find the distance Amber ran each hour the following calculation must be performed:
25/3 = X
8.333 = X
So Amber ran 8,333 kilometers during each hour, and the equation to determine that amount is 25/3 = X.

Answer:
The two triangles are congruent, or equal to each other.
Step-by-step explanation:
In order to solve this question, you first need to compare the measurements. Since AB and PQ both equal 4 cm, you know that they are congruent. Since BC and QR are also congruent, you know that the last two have to be congruent as well. Therefore, the triangles ABC and PQR are congruent, or equal, to each other.

The speed s (in miles per hour of a car driving on wet asphalt can be given by s = 3 square root d, where d is the stopping distance (in feet). What is the approximate stopping distance of a car traveling 80 miles per hour? Round your answer to the nearest hundredth.
Answer:
d = 711 miles
Step-by-step explanation:
The speed s of the car is given by :
[tex]s=3\sqrt{d}[/tex] ...(1)
Where
d is the stopping distance
We need to find the stopping distance of a car travelling at 80 mph.
Rearranging equation (1) for d.
[tex]s^2=9d\\\\d=\dfrac{s^2}{9}\\\\d=\dfrac{80^2}{9}\\\\d=711.1\ miles[/tex]
or
d = 711 miles
So, the required stopping distance is 711 miles.

You have to type up a 400 word paper. If you can type 25
words in 3 minutes, how long will it take you to type the
paper?
Answer:
48 minutes
Step-by-step explanation:
25=3 400/25=16x3=48
Answer:
48 minutes
Step-by-step explanation:
25 words - 3 minutes
400 words - x minutes
Cross multiply
25x = 400 x 3
25x = 1200
Divide both sides by 25
x = 1200/25
x = 48

-7b - 4(b + 7) = -3b - 4(b-2)
Answer:
b = -9
Step-by-step explanation:
-7b - 4(b + 7) = -3b - 4(b -2)
First we want to distribute the coefficients across the parentheses. To do so, we multiply the coefficient by every term within the parentheses.
-7b - 4(b + 7) = -3b - 4(b - 2)
-4 • b = -4b
-4 • 7 = -28
-4 • b = -4b
-4 • -2 = 8
Simplify the expression with these new values.
-7b - 4b - 28 = -3b - 4b + 8
Now we want to combine the like terms. First combine the variables.
-7b - 4b - 28 = -3b - 4b + 8
-11b - 28 = -7b + 8
Combine further by adding 7b to both sides.
-4b - 28 = 8
Combine the constants by adding 28 to both sides.
-4b = 36
Isolate b by dividing both sides by -4.
b = -9
This is your answer.
Check your answer by plugging b = -9 back into the original equation.
-7b - 4(b + 7) = -3b - 4(b - 2)
-7(-9) - 4(-9 + 7) = -3(-9) - 4((-9) - 2)
63 - 4(-2) = 27 - 4(-11)
63 + 8 = 27 + 44
71 = 71
Your answer is correct.
Hope this helps!
Answer:
-9 is the required answer of b
Step-by-step explanation:
-7b - 4(b + 7) = -3b - 4(b-2)
open bracket
-7b-4b-28=-3b-4b+8
-11b-28=-7b+8
-11b+7b=28+8
-4b=36
b=36/-4=-9
The graphs of linear functions f and g are shown on the grid below.
Which function is best represented by the graph of g?
Answer: g(x)=3f(x)
Step-by-step explanation:
So we know it isnt a translation. Which eliminates the first 2 answer choices. So its between the last 2. If it were 1/3 the grap would have been steeper.

Answer:
[tex] - (x - 1) {}^{2} + 5[/tex]
Step-by-step explanation:
F(x) is a transformation from h(x).
So our starting equation is
[tex] - (x - 1) {}^{2} - 1[/tex]
F(x) is also facing the same direction h(x) is so we dont have to reflect nothing across the x or y axis.
There isn't a vertical or horizontal stretch, compressions.
There isn't a horizontal shift as the x values stay in the same place.
There is a vertical shift. We can simply move h(x) up 6 units to get to f(x).
So our equation looks like.
[tex] - (x - 1) {}^{2} + 5[/tex]
The sales tax rate in Connecticut is 6.35%. Megan wants to buy a jacket with a $45.00 price tag. She has a gift card to the store she wants to use. What amount needs to be on the gift card for Megan to be able to buy the jacket using only the gift card?
Answer:
$47.86
Step-by-step explanation:
A tax is a compulsory amount levied by the government or an agency of the government on goods and services
Taxes increases the price of goods and services. Thus, the amount paid would increase by the tax rate
Amount that needs to be on the gift card = amount of tax + price of the jacket
Price of the jacket = $45
Amount of tax = percentage tax rate x price of the jacket
0.0635 x $45 = $2.86
$45 + $2.86 = $47.86

Evan and Dorinda make bracelets for a craft fair. Evan makes 10 bracelets the first day and 8 bracelets each day after that. Dorinda makes 8 bracelets the first day and 8 bracelets each day after that. If they make bracelets for 6 days, how many bracelets will they make in all? a. 567 b. 987653 c. 8765 d.65
Answer:
98 bracelets
Step-by-step explanation:
Number of days, n = 6
Evan:
= 10 + 8(n - 1)
= 10 + 8(6 - 1)
= 10 + 8(5)
= 10 + 40
= 50 bracelets
Dorinda
= 8n
= 8(6)
= 48 bracelets
Total bracelets they will make in all = Evan + Dorinda
= 50 + 48
= 98 bracelets
