How to find the volume of a composite solid
Answers
Answer:To find the volume of a composite solid, u identify the different parts it is made of, work out the volume of each part independently, and sum up the volumes of its parts. For composite prisms, where the bases are a composite shape, the area of the bases is the sum of the areas of the parts it is made of.

The points have been plotted on the coordinate graph.
Answer:
plot each coordinate pair onto the graph then solve for the function
Step-by-step explanation:
step one: plot each coordinate pain onto the coordinate graph
step two: fuse the vertical line test. Determining whether a relation is a function on a graph is relatively easy by using the vertical line test. If a vertical line crosses the relation on the graph only once in all locations, the relation is a function. However, if a vertical line crosses the relation more than once, the relation is not a function
What percent is equivalent to Two-fifths?
Possible Answers...
0.4%
2.5%
25%
40%
Answers
Answer:
40%
Step-by-step explanation:
2/5= 4/10
4/10= 40%
The percent that is equivalent to two-fifths is 40%. The correct option is 40%.
To determine the percent equivalent to two-fifths, we need to convert the fraction into a percentage.
The fraction two-fifths can be written as 2/5. To convert this fraction to a percentage, we divide the numerator (2) by the denominator (5) and multiply the result by 100.
2/5 x 100
= 0.4 x 100
= 40%
Therefore, the percentage equivalent to two-fifths is 40%.
Among the provided options:
0.4% is incorrect. It represents four-tenths of a percent, not 40%.
2.5% is incorrect. It represents two and a half percent, not 40%.
25% is incorrect. It represents one-fourth or 25%, not 40%.
40% is the correct answer, as explained above.
Hence, the option that represents the percent equivalent to two-fifths is 40%.

Keira said that if 6 tickets are sold, there should be 2 tickets left. Is Keira correct?
Answers
According to Keira, if 6 tickets are sold, there should be 2 tickets left. However, we don't have any information about the initial number of tickets available.
If the total number of tickets initially was 8, and 6 tickets were sold, then there would indeed be 2 tickets left, supporting Keira's statement.
However, if the total number of tickets initially was less than 8, or if the statement doesn't specify the initial number of tickets, we cannot determine if Keira's statement is correct.
Therefore, without additional information, we cannot determine the accuracy of Keira's statement.

What are some key words that can help us figure out this equation?
-Key words-

The key word "over" is letting us know we need to subtract.
So
What are we subtracting?
2 more key words are "2000" and "65".
This means we are subtracting 2000 by 65

When Connor was 16, he bought his first car. It had 1.67 x 10^5 miles on it. Connor is now 55 and wants to buy his dream car. He wants a
new car or a used one with low miles. The car he ends up buying has 4.35 x 10^3 miles.
How many times greater were the miles on his old car than his new car? Round to the nearest whole number.

First,we do 10^3
10 x 10 x 10
100 x 10
1000
Then we bring down
4.35 and we multiply it by 1000
And Last, we get
4350 as the answer
The miles on Connor's old car were 39 times greater than the miles on his new car.
What is the distance?A mathematical number known as distance measures "how much ground an object has traveled" while moving. Distance is defined as the product of speed and time.
To solve this problem, we need to divide the number of miles on Connor's old car by the number of miles on his new car and round the result to the nearest whole number.
The number of miles on Connor's old car is 1.67 x 10⁵ miles and the number of miles on his new car is 4.35 x 10³ miles, so the number of times greater the miles on his old car are than his new car is:
(1.67 x 10⁵ miles) / (4.35 x 10³ miles) = 38.6
Rounded to the nearest whole number, this is 39.
Therefore, the miles on Connor's old car were 39 times greater than the miles on his new car.

The function for the points are y = -15x - 5
How to determine the functionFrom the information given, we have that;
The points are;
(1/3,0) (-2 3/4,0) and (0,-5)
Using the point-slope form of a linear equation, we have;
y - y₁ = m(x - x₁)
Such that;
m is the slope of the liney - y₁ and (x - x₁) are the pointsUsing (1/3, 0) and (0, -5), we have that the slope is;
m = (0 - (-5))/0 -1/3)
expand the bracket
= 5 / (-1/3)
= -15
Now, take any of the given points and substitute the values
Using (1/3, 0), we get;
y - 0 = -15(x - 1/3).
y = -15x - 5.

The function for the points solved by (1/3,0) (-2 3/4,0) and (0,-5) solved by point slope form is \(a=-15b-5\)
We have given the points:
(1/3,0) (-2 3/4,0) and (0,-5)
Using the formula of linear equation
\(a-\)\(a_{1}\)\(=x[b-b_{1}]\)
Where we will consider (1/3,0) = \(a-a_{1}\) and (0,-5) = \(b-b_{1}\)
that is 1/3 = \(a\), 0 = \(a_{1}\) and
0 = \(b\), -5 = \(b_{1}\)
\(x\) refers to the slope of line (take any variable)
Now for finding the value of \(x\),
\(x=a-a_{1}/b-b_{1}\)
inserting the values,
\(x=[0-[-5]]/[0-1/3]\\x= -15\)
Substitute the value of \(x\) in the equation
\(a-0=-15[b-1/3]\)
By simplifying the equation, we get
\(a=-15b-5\)
