Answers
Answer: 64.8 mph
Step-by-step explanation:
Given
Arriving time is 6 hours
return time is 4 hours
The average speed of returning 81 mph
Distance traveled while returning
[tex]\Rightarrow d=81\times 4=324\ miles[/tex]
the average speed of the entire trip is
[tex]\Rightarrow v_{avg}=\dfrac{2\times 324}{6+4}=\dfrac{648}{10}=64.8\ mph[/tex]

Ms. Stephanie bought a package of pens. Out of every 10 pens, 1 are black. If there are 30 pens in
the pack, what fraction of the pens in the pack are black? What percent of the pens in the pack are
black?
What fraction of the pens in the pack is black?
Answers
Answer:
1/10. 10% Since there are 30 pens, there are 3 black ones.
Answer:
The fraction of the black pens in the pack is [tex]\frac{3}{30}[/tex]
The percent of the black pens in the pack is 10%
Step-by-step explanation:
If 1/10 pens are black, we can use this same proportion to find how many black pens will be in the pack of 30.
Using this, there will be 3/30 pens that will be black, since 3/30 is equivalent to 1/10 when reduced.
So, the fraction of the black pens in the pack is [tex]\frac{3}{30}[/tex]
To find the percent, divide 3 by 30:
3/30
= 0.1 (10 percent)
So, the percent of the black pens in the pack is 10%

y = mx + b -2 = 3(4) + b -2 = 12 + b -14 = b; the y-intercept is -14 What is wrong with this answer?
Answers
Answer:
There is nothing wrong with the answer obtained
Step-by-step explanation:
Given the equation :
Y = mx + b
-2 = 3(4) + b
-2 = 12 + b
-14 = b
The correct calculation :
Y = mx + b
-2 = 3(4) + b
-2 = 12 + b
Subtract 12 from both sides
-2 - 12 = 12 + b - 12
-14 = b
Based on the details of the question given, the intercept, b is - 14 ;
Hence, there is nothing wrong with the answer

Heidi is making a tower using sugar cubes. Each sugar cube has a side length of 1 cm. Each layer has 4 sugar cubes, arranged in a 2 by 2 pattern. The completed tower has a volume of 24 cm3. How many layers of sugar cubes are in the tower?
Answers
Answer:
3 layers
Step-by-step explanation:
Given
[tex]L = 1cm[/tex] --- side length of the cube
Each layer = 2 * 2 cube
[tex]Volume = 24cm^3[/tex]
Required
Determine the number of layers
First, we calculate the volume of each layer:
The length of the layer is:
[tex]Length = 2 * L[/tex]
[tex]Length = 2 * 1cm[/tex]
[tex]Length = 2cm[/tex]
Next, we calculate the volume of each layer:
[tex]Volume = Length^3[/tex]
[tex]Volume = (2cm)^3[/tex]
[tex]Volume = 8cm^3[/tex]
The number of layer is calculated by dividing the volume of the tower by the volume of each layer
[tex]Layers = \frac{24cm^3}{8cm^3}[/tex]
[tex]Layers = 3[/tex]
"The Martin family's truck gets an average of 25 miles per gallon of fuel. Predict how many miles they will be able to get from 7 gallons of fuel by using equivalent rates." (Explain with fractions/ equivalent rate in detail pls)
Answers
Answer:
175 miles
Step-by-step explanation:
Average of 25 miles per gallon of fuel
Miles : gallons = 25 : 1
Predict how many miles they will be able to get from 7 gallons of fuel by using equivalent rates
Let x = number miles
Miles : gallons = x : 7
To find x
25 : 1 = x : 7
25/1 = x/7
Cross product
25*7 = 1*x
175 = x
x = 175 miles
Number miles = 175

Answers
Answer:
Both types of angles, complementary angles, supplementary angles.
Step-by-step explanation:
Hope this helps
Both types of angles, Complementary angles, supplementary angles are pairs of angles whose measures have specific sums. Therefore, option A is the correct answer.
What are complementary angles?Two angles are said to be complementary angles if they add up to 90 degrees. In other words, when complementary angles are put together, they form a right angle (90 degrees).
Supplementary angles refer to the pair of angles that always sum up to 180°. These two angles are called supplements of each other.
Therefore, option A is the correct answer.
