Answer:

B. 200 cubic feet

Step-by-step explanation:

There are two prisms: the triangular prism and the rectangular prism

first lets start with the triangular one:

remember that for a right triangular prism (this one), the area is 1/2 x base x height x length

another way to think about it is to find the area of the triangle and then multiply that by the thickness

The base is 4 feet and the height is the same as the rectangular prism, which is 5

and the length is 4 ft (same as rectangular prism)

so 1/2 x 4 x 5 x 4 is 40

next lets do the rectangular prism

remember the volume is length x width x height

8 x 4 x 5 = 160

now we simply add the volume of the two prisms

40 + 160 = 200

and there's you're answer :)

hope that helps!

Answer:

Step-by-step explanation:

Area of triangular face = 0.5×4×5 = 10 ft²

Volume of triangular prism = 10×4 = 40 ft³

Volume of rectangular prism = 8×4×5 = 160 ft³

Total volume = 40+160 = 200 ft³

[tex](d)[/tex] [tex]\frac{4}{8}>\frac{2}{6}[/tex]

Step-by-step explanation:

Given

[tex]\frac{1}{4} <\frac{1}{6}[/tex]

[tex]\frac{5}{10}<\frac{3}{6}[/tex]

[tex]\frac{1}{2}>\frac{1}{3}[/tex]

[tex]\frac{4}{8}>\frac{2}{6}[/tex]

[tex]\frac{3}{5}>\frac{4}{5}[/tex]

Required

Select the unit fractions

If we are to go by what a unit fraction means: it means that the numerator of the fraction must be 1 and must be written as a single fraction i.e. [tex]\frac{1}{2}[/tex] and not as an inequality i.e. [tex]\frac{3}{5}>\frac{4}{5}[/tex]

Given the format of the question, what is required of the question is to select all correct inequality.

[tex](a)[/tex] [tex]\frac{1}{4} <\frac{1}{6}[/tex]

Convert to decimals

[tex]0.25 < 0.167[/tex] ---- This is not true because [tex]0.25 > 0.167[/tex]

[tex](b)[/tex] [tex]\frac{5}{10}<\frac{3}{6}[/tex]

Convert to decimals

[tex]0.5 < 0.5[/tex] ---- This is not true because [tex]0.5 = 0.5[/tex]

[tex](c)[/tex] [tex]\frac{1}{2}>\frac{1}{3}[/tex]

Convert to decimals

[tex]0.5 > 0.33[/tex] ---- This is true

[tex](d)[/tex] [tex]\frac{4}{8}>\frac{2}{6}[/tex]

Convert to decimals

[tex]0.5 > 0.33[/tex] ---- This is true

[tex](e)[/tex] [tex]\frac{3}{5}>\frac{4}{5}[/tex]

[tex]0.6 > 0.8[/tex] --- This is not true because [tex]0.6 < 0.8[/tex]

So: the true inequality is:

[tex](d)[/tex] [tex]\frac{4}{8}>\frac{2}{6}[/tex]

Answer:

B

Step-by-step explanation:

B shows a parabola, which is a quadratic equation, not a linear one.

The association between two numerical variables measured for the same individuals is displayed in a scatterplot. One variable's values are displayed on the horizontal axis, and the other variable's values are displayed on the vertical axis. On the graph, each individual in the data is represented by a point.

A scatter plot is a type of plot or mathematical diagram using Cartesian coordinates to display values for typically two variables for a set of data. If the points are coded, one additional variable can be displayed.

here, we have,

we know that,

The relationship between two economic phenomena, such as employment and output, inflation and retail sales, and taxes and economic growth, can be visually illustrated using scatter plots.

Spread Plots. Points on a scatter (XY) plot depict how two sets of data relate to one another. Each dot in this illustration represents a person's weight in relation to their height. (The information is displayed as "Cartesian (x, y) Coordinates")

It's 271 on Khan Academy

The sample space size that Angela wants to use for the employees who are satisfied with their benefits is. 271

In statistics, the margin of error is the level of inaccuracy in the findings of surveys using random samples. Less reliance on survey or poll results is indicated by higher statistical margins of error.

Given that,

[tex]\^p[/tex] = 0.5

1 - [tex]\^p[/tex]  = 1 - 0.5= 0.5

margin of error = E = 5% = 0.05

At 90% confidence level

= 1 - 0.90 = 0.10

0.10/2 =0.05

Z/2 = 1.645 ( Using z table )

Sample size = n = (Z/2 / E)² x   (1 - [tex]\^p[/tex])²

= (1.645 / 0.05)² * 0.5 x 0.5

=270.6

Sample size = 271

The required sample size is 271.

Answer: 2.5 hours

Step-by-step explanation:

Given

Distance between A to B town is [tex]d=145\ miles[/tex]

Bus speed is 9 miles per hour faster than car

time taken by car is 2 hours and 54 minutes i.e.

[tex]t=2+\dfrac{54}{60}=2+0.9=2.9\ hr[/tex]

Speed of car is v

[tex]\Rightarrow v=\dfrac{d}{t}=\dfrac{145}{2.9}=50\ mph[/tex]

Speed of bus is [tex]v+8=50+8=58\ mph[/tex]

time taken by bus is t'
