Answer:
Each book weighs 2.5 pounds.
Step-by-step explanation:
75/2.5 is 30. Or you could also get the answer by 30* 2.5 which it would be 75. So, therefor, the answer is 2.5.
Answer:
2.5lb
Explanation:
In equation form the question is asking for x in
[tex]30(x) = 75[/tex]
Since multiplication is reversible (to be division), we can switch the equation up.
[tex]75[/tex] ÷ [tex]30 = x[/tex]
So the answer is
[tex]75[/tex] ÷ [tex]30 = 2.5[/tex]
explain how sandbars in the ocean are formed.
Answer:
Sandbars begin forming underwater. As waves break, this pulls material from the shoreline, migrating further into the ocean. During heavy storms, large waves can build sandbars far from shore, until they rise above the water's surface.
Step-by-step explanation:
Water brings sand and other sediment to the surface and creates a strip of land that lays between water.

There are 20 children at a library. Six of the children have a averahe age of 5 years. The remaining children have a sverage age of 8 years. What is the average age of the children at the library?
Answer: The average age of the children at the library is 7.1 years.
Step-by-step explanation:
Given,
Out of 20 children, six of the children have an average age of 5 years,
Thus, the sum of the ages of 6 students = 5 × 6 = 30
( Total sum of observations = Their Average × Total numbers of the observations )
Now, remaining students = 20 - 6 = 14,
Since, the remaining children have an average age of 8 years.
Thus, the sum of the ages of 14 students = 14 × 8 = 112,
Total sum of the ages of 20 students = 30 + 112 = 142
=142/20
= 7.1 years
Answer:
The average is 7.1 years!
Step-by-step explanation:
6 children = average of 5 years
14 children = average of 8 years

An engineer traveled 150 mi by car and then an additional 630 mi by plane. The rate of the plane was three times the rate of the car. The total trip took 8 h. Find the rate of the car.
Answer:
Step-by-step explanation:
150 mile by car x mph
630 mile by plane 3x mph
Total travel time equal 8 hours
150 / x mile / (mile / hour) = hour
630 / 3x mile / (mile / hour) = hour
150/x + 630/3x = 8 hours
450/3x + 630/3x = 8 hours
450 + 630 = 8(3x) = 24x
1080 = 24x
45 = x the rate of the car is 45 mph

Based on this survey, what is the probability that a person texts over 50 messages per month given that the person is between the ages of 23 and 60? A) 157/229 B) 157/312 C) 157/384 D) 157/456
Answer:C
Step-by-step explanation:I took the test got a
The probability that a person texts over 50 messages per month given that the person is between the ages of 23 and 60 is 157/456.
What is probability?Probability is a measure of the likelihood of an event to occur. Many events cannot be predicted with total certainty. We can predict only the chance of an event to occur i.e., how likely they are going to happen, using it.
Given is table showing the results of a survey on the number of text messages per month for people of different ages.
we need to find the probability that a person texts over 50 messages per month given that the person is between the ages of 23 and 60,
P(E) = favorable outcomes / total outcomes
Favorable outcomes = 157
Total outcomes = 456
Hence the required probability = 157 / 456
Hence the probability that a person texts over 50 messages per month given that the person is between the ages of 23 and 60 is 157/456.

Ella is making a kite in the shape of a triangular prism, but with both ends open. Which net shows the faces that
would be used to calculate surface area shaded?
Answer: the answer is the second one :)
Step-by-step explanation:
The net is shown in the picture that can used to calculate surface area shaded.
What is quadrilateral?It is defined as the four-sided polygon in geometry having four edges and four corners.
We know that kite is quadrilateral, having:
Two pairs of congruent sides.It has one pair of opposite congruent angles.The diagonals of a kite are perpendicular.One diagonal is bisected.The top and bottom angles are bisected butKite does not have congruent diagonals.
As we have given that, Ella is making a kite in the shape of a triangular prism, but with both ends open.
Thus, the net is shown in the picture that can used to calculate surface area shaded.

Answer:
The x-intercepts are 1 and 3
The y-intercept is 3
The vertex is (2,-1)
The line of symmetry is x=2
Step-by-step explanation:
To find the x-intercepts, find where the graph intersects the x-axis, or the horizontal line. To find the y-intercept, find where the graph intersects the y-axis, or the vertical line. To find the vertex, find the coordinate where the graph is at its lowest point (or highest if it is flipped upside down). To find the line of symmetry, simple use the x-coordinate of the vertex and say x= (the x-coordinate)
