Write an equivalent multiplication expression. Then, find the quotient in its simplest form. Use a model to support your response. 1 4 ÷ 2 and 2 3 ÷ 6
Step-by-step explanation:
Let the integers be a, b and c. To model the expression generally;
[tex]\dfrac{a}{b} \div c = \dfrac{a}{b} \times \dfrac{1}{c}\\= \dfrac{a}{bc}[/tex]
Using the model to solve the following expression given
a) [tex]\dfrac{1}{4} \div 2[/tex]
[tex]= \dfrac{1}{4} \times \dfrac{1}{2}\\= \dfrac{1}{4*2}\\= \dfrac{1}{8}[/tex]
b)
[tex]= \frac{2}{3} \div 6 \\= \dfrac{2}{3} \times \dfrac{1}{6}\\= \dfrac{2}{3*6}\\\\= \dfrac{2}{18}\\= \dfrac{2}{9}[/tex]

A firefighter needs to lean a ladder against a wall of a building to reach a window. How far away from the base of the building should he/she place the foot of the ladder? Ladder is 25 feet long, window is 23.8 feet high in the building.
Answer:
7.7 feet
Step-by-step explanation:
Let the distance from the base of the building to the foot of the ladder be represented by x. Ladder is 25 feet long, while window is 23.8 feet high.
The length of the ladder, the height of the window and the distance from base of building to foot of ladder describes a right angled triangle.
Thus, applying the Pythagoras theorem;
[tex](25)^{2}[/tex] = [tex](23.8)^{2}[/tex] + [tex]x^{2}[/tex]
625 = 566.44 + [tex]x^{2}[/tex]
625 - 566.44 = [tex]x^{2}[/tex]
58.56 = [tex]x^{2}[/tex]
⇒ x = [tex]\sqrt{58.56}[/tex]
= 7.653
The foot of the ladder should be placed 7.7 feet away from the base of the building.

A line passes through (3, 7) and (6, 9). Which equation best represents the line?
y = 3 over 2x + 5
y = 2 over 3x + 5
y = 3x + 2
y = 2 over 3x + 2
Answer:
B. [tex]y = \frac{2}{3} x + 5[/tex]
Step-by-step explanation:
Let's use the slope equation first. The slope equation is as follows:
[tex]\frac{y2-y1}{x2-x1} = slope[/tex]
This is what is given in the equation:
Point (3,7)Point (6,9)Let's label each component of the equation using these points:
y2 = 9
y1 = 7
x2 = 6
x1 = 3
Now, plug these into the equation
[tex]\frac{9-7}{6-3} = \frac{2}{3}[/tex]
We can now eliminate A and C of the answer choices.
Now let's find the y intercept
Right now we have the following equation
[tex]y = \frac{2}{3} x+ (y intercept)[/tex]
In order to find the y intercept we need to plug in one of the given points into the equation. Let's use point (3,7).
The equation should look like this now:
[tex]7 = \frac{2}{3}(3) + (yintercept)[/tex]
Now lets solve for the y-intercept
[tex]7 = \frac{2}{3}(3) + (yintercept)\\7 = \frac{6}{3} + (yintercept)\\7 = 2 + (yintercept) \\5 = yintercept[/tex]
Now that we found the y-intercept is 5 we have our full equation!
[tex]y = \frac{2}{3} x + 5[/tex]
Hope this helps!!

Danica is saving money to buy a used car in six months. She needs to save $1500 for a down payment in order to be able to finance the rest. She gets paid $180 per week at her part-time job. How much money will she need to save out of every weekly paycheck to reach her savings goal of $1500 in six months? Show the calculations:
Answer:
$62.5Step-by-step explanation:
Step one:
Given data
Danica's goal is to save $1500
her pay is $180 weekly.
the duration is 6months
in a month we have 4 weeks
in 6months there are 6*4= 24 weeks
Step two:
In 24 weeks Danica's earnings will be 24*180= $4320
nevertheless, she only needs $1500 for the 24 weeks to make the down payment
So per week, she will need to save 1500/24= $62.5

Answer:
g = 7 1/3
Step-by-step explanation:
Add 5 to both sides so it cancels out. 3g = 22Divide both sides by 3. g = 7.333...7.333... and 7 1/3 are equivalent, so just put either one.
Find each unit rate. Determine which is lower. Drag and drop the correct rate or letter into each of the boxes to complete the sentences. Ingredient C: 1/5 cup for 3/4 serving or Ingredient D: 1/4 cup for 4/5 serving.
Answer:
4/15 < 5/16
Ingredient C < Ingredient D
Hence ingredient C has a lower cup per serving than ingredient D
Step-by-step explanation:
Given the unit rates :
C: 1/5 cup for 3/4 serving or Ingredient
D: 1/4 cup for 4/5 serving
C : 1/5 cup for 3/4 serving
1/5 ÷ 3/4
1/5 * 4/3
= 4 / 15
= 0.2667
D: 1/4 cup for 4/5 serving
1/4 ÷ 4/5
1/4 * 5/4
= 5 / 16
= 0.3125
5/16 > 4/15 ;
Ingredient C < Ingredient D
Hence ingredient C has a lower cup per serving than ingredient D

A slug travels 3 centimeters in 3 minutes. A snail travels 6 centimeters in 6 minutes. Both travel at constant speeds. Mai says, “The snail was traveling faster because it went a greater distance.” Do you agree with Mai's reasoning
Answer:
No
Step-by-step explanation:
If you find the rate, they are the same.
3 minutes/3= 1 minute
3cm/3= 1 cm
Slug= 1 cm per minute
6 minutes/6= 1 minute
6cm/6= 1 cm
Snail= 1 cm per minute

Some people advise that in very cold weather, you should keep the gas tank in your car more than half full. Irene's car had 6.4 gallons in the 14-gallon tank on the coldest day of the year. Irene filled the tank with gas that cost $3.90 per gallon. How much did Irene spend on gas?
Answer:
$24.96
Step-by-step explanation:
Total number of gallons irede had in his tank = 6.4gallons
Price per gallon is $3.90
To get the cost of 6.4gallons;
If 1 gallon = $3.90
6.4gallons = $x
Cross multiply
1 * x = 3.90 * 6.4
x = 24.96
Hence Irene spent $24.96 on gas

i do not really understand but use this formula
= average acceleration
v = final velocity
v_0 = starting velocity
t = elapsed time
