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.”

You and two friends are playing basketball. You make 7 out of 15 shots. Your first friend makes 6 out of 10 shots and your second friend makes 5 out of 12 shots. Who is the better shooter? How would you solve this problem using what you know about rational numbers?
Two containers, A and b begin with equal volumes of liquid. 120 mL is then poured from a to B. Container b now contains four times as much liquid as A. Find the volume of liquid left in container a at the end
The volume of liquid left in container a at the end is 80 mL.
Let's denote the initial volume of each container as ( V ) mL. After pouring 120 mL from A to B, the volume of liquid in A decreases to ( V - 120 ) mL and the volume in B increases to ( V + 120 ) mL.
We're given that after this transfer, the volume in B is four times the volume in A:
[tex]\[ V + 120 = 4(V - 120) \][/tex]
Now, we solve for ( V ):
V + 120 = 4V - 480
120 + 480 = 4V - V
600 = 3V
V = [tex]\frac{600}{3}[/tex] = 200
So, the initial volume in each container was 200 mL. After pouring, A has ( 200 - 120 = 80 ) mL left.
Using this how do you solve the equation: f(g(3))

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.

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

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
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.

Two scientists are measuring lava temperatures. One scientist records temperature of 1725 degrees Fahrenheit. The other scientist records a temperature of 950 degrees Celsius. Which is the greatest temperature? (Use C= 5/9(F - 32)
Final answer:
To compare temperatures, convert them to the same unit. In this case, 1725°F is the greatest temperature between 1725°F and 1742°F.
Explanation:
Converting temperatures: To compare temperatures, we must convert them to the same unit. The first scientist recorded 1725°F, and the second scientist recorded 950°C. Converting 950°C to Fahrenheit, we get 1742°F. Therefore, 1725°F is the greatest temperature.

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.
