Final answer:
To calculate the cost of 10 pencils when seven pencils cost $0.84, you find the price per pencil by dividing $0.84 by 7, which equals $0.12 per pencil. Then, multiply $0.12 by 10 to get the total cost of 10 pencils, which is $1.20.
Explanation:
To answer the question, we first need to find the cost of one pencil. Since seven pencils cost $0.84, we can divide that amount by seven to get the cost of one pencil.
Here is the calculation:
Cost of seven pencils = $0.84
Cost of one pencil = $0.84 ÷ 7
Cost of one pencil = $0.12
Now that we know the cost of one pencil, we can find the cost of 10 pencils by multiplying this amount by 10.
Here is the calculation:
Cost of 10 pencils = $0.12 × 10
Cost of 10 pencils = $1.20Therefore, the cost of 10 pencils is $1.20.

Jimmy ran m miles in t minutes. What was his speed?
To find Jimmy's speed, we use the formula speed = distance/time and represent his speed as m miles / t minutes.
Explanation:To find Jimmy's speed, we need to use the formula speed = distance/time. In this case, Jimmy ran m miles in t minutes. So, his speed can be represented as:
Speed = m miles / t minutes

Where the numbers are on top of each other they are a fraction, and where there is a / it is the long division symbol.
Its probaly: B, D, and E
Answer:
C - 645 ÷ 1100
E - 645 /(over) 1100
F - 1100 )645
Step-by-step explanation:
Use words to show how each division problem is read:
a. 12 ÷ 6 b. 12/6 c. 6)12
For all three division symbols, we say “divided by.” The division in
A is read from left to right: “twelve divided by six.”
The division in B is read from top to bottom: “twelve divided by
six.”
The division in C is written with a division box. We read the number
inside the box first: “twelve divided by six.”
We see that all three problems are read the same. Each problem
shows the same division “twelve divided by six.”
start at 5 create a pattern that multiplies each no. by 3 and subtracts 2 stop when you have 5 no.
Final answer:
The mathematical pattern involves starting with the number 5, multiplying by 3, and subtracting 2, which gives the sequence: 5, 13, 37, 109, 325.
Explanation:
The pattern described would involve starting with the number 5 and repeatedly applying the same mathematical operation, which is to multiply by 3 and then subtract 2, stopping after obtaining five numbers in total. Let's demonstrate this step-by-step:
Start with 5Multiply by 3: 5 × 3 = 15Subtract 2: 15 - 2 = 13 (This gives us our second number)Now use 13: 13 × 3 = 39Subtract 2: 39 - 2 = 37 (Third number)Next, take 37: 37 × 3 = 111Subtract 2: 111 - 2 = 109 (Fourth number)Finally, use 109: 109 × 3 = 327Subtract 2: 327 - 2 = 325 (Fifth number)So the series of five numbers created by this pattern is: 5, 13, 37, 109, 325.
Beau's recipe for granola bars calls for 3 1/2 cups of oatmeal. He only has a 1/6 cup scoop. How many scoops of oatmeal will he need to complete the recipe?
There will be [tex]\boxed{\bf 21}[/tex] scoops of oatmeal to complete the recipe.
Further explanation:
Given that Beau’s recipe of granola bars contains [tex]3\frac{1}{2}[/tex] cups of oatmeal.
Beau’s has only [tex]\frac{1}{6}[/tex] cup scoop.
Our aim is to find the number of scoops of oatmeal Beau’s needed to complete the recipe for granola bars.
Total cups of oatmeal are [tex]3\frac{1}{2}[/tex].
First we have to convert the total cups of oat meal to proper fraction.
[tex]\begin{aligned}\text{Cups of oatmeal for the recipe}&=\dfrac{(3\cdot 2)+1}{2}\\&=\dfrac{6+1}{2}\\&=\dfrac{7}{2}\end{aligned}[/tex]
There is only [tex]\frac{1}{6}[/tex] cup scoop.
Since there are [tex]\frac{7}{2}[/tex] cups of oatmeal and [tex]\frac{1}{6}[/tex] cup scoop, therefore, number of scoops required to complete the meal are calculated as follows:
[tex]\begin{aligned}\text{Number of scoops required}&=\dfrac{\frac{7}{2}}{\frac{1}{6}}\\&=\dfrac{7}{2}\cdot 6\\&=7\cdot 3\\&=21\end{aligned}[/tex]
The total number of scoops is obtained in whole number; therefore, this is our final answer.
Therefore, [tex]\boxed{\bf 21}[/tex] scoops of oatmeal are needed by Beau’s to complete the recipe of granola bars.

Further explanation:
Given:
Beau's recipe from granola bars calls for [tex]3\dfrac{1}{2}[/tex] cups of oatmeal.
He only is [tex]\dfrac{1}{6}\:{\text{scoop}[/tex]
Explanation:
The number of cups of oatmeal that are called for the recipe are [tex]3\dfrac{1}{2}.[/tex]
Solve the improper fraction [tex]3\dfrac{1}{2}[/tex] to obtain the proper fraction.
[tex]\begin{aligned}{\text{Fraction}}&= \frac{{2 \times 3 + 1}}{2}\\&=\frac{{6 + 1}}{2}\\&= \frac{7}{2}\\\end{aligned}[/tex]
The Beau has [tex]\dfrac{1}{6}{\text{ scoop}}.[/tex]
The number of scoops that are required to complete the recipe can be obtained as follows,
[tex]\begin{aligned}N&=\dfrac{{{\text{total cups of oatmeal}}}}{{{\text{the fraction of scoop Beau has}}}}\\&=\dfrac{{\dfrac{7}{2}}}{{\dfrac{1}{6}}}\\&= \frac{7}{2} \times 6\\&=\dfrac{{42}}{2}\\&= 21\\\end{aligned}[/tex]
The number of scoops required to complete the oatmeal is [tex]21{\text{ scoops}}.[/tex]
Therefore, [tex]\boxed{21}[/tex] number of scoops of oatmeal will he need to complete the recipe.

Convert the fraction into a decimal: 35/10 =
Answer: 3.5
Step-by-step explanation: In order to write [tex]\frac{35}{10}[/tex] as a decimal, we need to find a fraction that is equivalent to [tex]\frac{35}{10}[/tex] with a 100 in the denominator. Notice that if we multiply the numerator and denominator of [tex]\frac{35}{10}[/tex] by 10, we get the equivalent fraction [tex]\frac{350}{100}[/tex] which we can now write as a decimal. Remember that the hundredths place is two places to the right of the decimal point. Therefore, we can write [texfrac{350}{100}[/tex] as 3.5.

Relationship A has a greater rate than Relationship B. This table represents Relationship B.
Hours worked 2 4 5 8
Amount paid ($) 25 50 62.50 100
Which equation could represent Relationship A?
Hours worked is represented by x and Amount paid is represented by y.
Select each correct answer.
y = 13x
y = 11.5x
y = 12.75x
y = 12.25x
Answer:
y = 13x ; and y = 12.75x
Explanation:
The rate of change is another name for slope. To find the slope of Relationship B, we use the formula
[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]
Using the first two points, we have
m = (50-25)/(4-2) = 25/2 = 12.5
This means that anything with a rate of change greater than 12.5 works in this problem.
The equations listed for Relationship A are in slope-intercept form, y=mx+b, where m is the slope and b is the y-intercept (in all of these, b = 0).
In the first equation, m = 13; in the second equation, m = 11.5; in the third equation, m = 12.75; and in the fourth equation, m = 12.25. The only ones with higher slopes than Relationship B are the first and the third one.

the triangles shown below must be congruent. right awnsers only please.
Answer: false
Step-by-step explanation:
Answer:
False
Step-by-step explanation:
Properties of congruent triangle :
SSS -"side, side, side" and means that we have two triangles with all three sides equal.
ASA- "angle, side, angle" and means that we have two triangles where we know two angles and the included side are equal.
SAS -"side, angle, side" and means that we have two triangles where we know two sides and the included angle are equal.
AAS -"angle, angle, side" and means that we have two triangles where we know two angles and the non-included side are equal.
Since the given triangles does not satisfy any property
So, the given triangles are not congruent.
So, Option B is true
Hence False
