Answer:

180 mm³

Step-by-step explanation:

The polyhedron is an oblique rectangular prism

Area of the oblique rectangular prism = base area * height

height = z = 4 mm

Base area = L*W

L = y = 9 mm

W = x = 5 mm

Base area = 9*5 = 45 mm²

Area of the oblique rectangular prism = 45*4 = 180 mm³

Answer:

208m²

Step-by-step explanation:

Okay, so you can split this abomination into a rectangle, another rectangle, and a square, so we're going to start with the rectangle to the far left:

The formula for the area of a rectangle or square is length x width, so we just have to plug:

4 x 8 = 32

Now we do the next rectangle, but we have to figure out the length first, so:

4 + 4 = 8

Now we plug:

8 x 4 = 32 (I now realize that the rectangles are even and we could've just multiplied the first one by two, but it's always good to check)

Now we do the square:

12 x 12 = 144

Now we add it all together:

32 + 32 + 144 = 208

So the area of the figure is 208m²

if this is wrong, let me know so I can fix it

hope this helps:)

Answer:

3/8

Step-by-step explanation:

1. Display your knowledge to the problem

You know that a whole pizza must be 8/8 slices, right? And you know that Justin ate 1/4 of the pizza and Dan ate 3/8. Good, that's all you need to know so far.

2. Add 1/4 and 3/8

You have to figure out how much they ate all together. First, find a common denominator. Let's do... hmmm, 8 is perfect! 3/8 is already in its simplest form but what about 1/4? Well, 1/4 is 2/8 in simplest form. There we go! And 3/8 plus 2/8 is 5/8!

3. What's left of the pizza?

Well, we have 5/8 eaten and in whole, there's 8 slices, so that must mean 3 slices are still there and haven't been eaten yet! 3 slices = 3/8

Hope that helps!

Answer:

How can you determine whether a given number makes an equation true?

Determine whether a number is a solution to an equation.

   Substitute the number for the variable in the equation.

   Simplify the expressions on both sides of the equation.

   Determine whether the resulting equation is true. If it is true, the number is a solution. If it is not true, the number is not a solution.

Answer:

critical value = 5.29

Step-by-step explanation:

Given that they are divided into 4 groups and a sample of 5 test was selected

N = 5 * 4 = 20

k = 4

∝ = 0.01

Df for numerator ( SS group )= k - 1 = 3

Df for denominator ( SSE group )  = N - k = 20 - 4 = 16

DF ( degree of freedom )

Next we will use the F table to determine the critical value

Critical value =   [tex]F_{16,3,0.01}[/tex] = 5.29

Answer:

Ivy initially put $ 650 in the account.

Step-by-step explanation:

Given that Ivy deposited some money into a savings account that earns 1% annual simple interest, and at the end of 5 years, she earned $ 32.50 in interest, to determine how much money did she put into the account initially, the following calculation must be performed:

32.50 / 5 = 6.5

1 = 6.5

100 = X

100 x 6.5 = X

650 = X

Therefore, Ivy initially put $ 650 in the account.

Answer:

As the calculated value of z does not lie in the critical region the null hypothesis is accepted that the GPA mean of the night students is the same as the GPA mean of the day students.

Step-by-step explanation:

Here n= 20

Sample mean GPA = x`= 2.84

Standard mean GPA = u= 2.55

Standard deviation = s=  0.45.

Level of Significance.= ∝ = 0.01

The hypothesis are formulated as

H0: u1=u2   i.e the GPA of night students is same as the mean GPA of day students

against the claim

Ha: u1≠u2

i.e the GPA of night students is different from the mea GPA of day students

For two tailed test  the critical value is  z ≥ z∝/2= ± 2.58

The test statistic

Z= x`-u/s/√n

z= 2.84-2.55/0.45/√20

z= 0.1441

As the calculated value of z does not lie in the critical region the null hypothesis is accepted that the GPA mean of the night students is the same as the GPA mean of the day students.

The scenarios which gives a value of 0.4 is depicted by the equations B and C

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

a)

Jesse rode 4 out of 10 miles on his bike.

So , the fraction is A = 4/10 = 0.4

b)

Jesse finished 40 out of 100 math problems.

So , the fraction is A = 40/100 = 0.4

Hence , the equation is A = 0.4

Step-by-step explanation:

Answer:

The mass of the radioactive sample after 40 minutes is 12.8 g.

Step-by-step explanation:

The mass of the sample can be found by using the exponential decay equation:

[tex] N_{t} = N_{0}e^{-\lambda t} [/tex]

Where:

N(t): is the amount of the sample at time t =?

N₀: is the initial quantity of the sample = 120 g

t = 40 min

λ: is the decay constant =  0.056 min⁻¹

Hence, the mass of the sample after 40 min is:

[tex] N_{t} = N_{0}e^{-\lambda t} = 120g*e^{-0.056min^{-1}*40 min} = 12.8 g [/tex]

Therefore, the mass of the radioactive sample after 40 minutes is 12.8 g.

-----

Mrs. Reed DATA:

rate = 60 mph ; time = x - 3.5 hrs ; distance = 60x - 210 miles

Equation:

40x = 60x -210

-20x = -210

Answer:

The critical value is T = 3.143.

Step-by-step explanation:

The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So

df = 7 - 1 = 6

98% confidence interval

Now, we have to find a value of T, which is found looking at the t table, with 6 degrees of freedom(y-axis) and a confidence level of [tex]1 - \frac{1 - 0.98}{2} = 0.99[/tex]. So we have T = 3.143.

The critical value is T = 3.143.

The expressions that are the result of decreasing x by 80% will be (1 - 0.80)x, x - (80/100)x, and (20/100)x. Then the correct options are A, C, and E.

The quantity of anything is stated as though it were a fraction of a hundred. A quarter of 100 can be used to express the ratio. Per 100 is what the term percent signifies. The symbol ‘%’ is used to symbolize it.

The expressions that are the result of decreasing x by 80%.

We know that if something is decreased by a percentage p% then the percentage is written as (1 - p%). Then the expression is written as,

⇒ [(100 - 80) / 100]x

Then the expression can be written as,

⇒ [(100 - 80) / 100]x

⇒ x - (80/100)x

⇒ x - 0.80x

⇒ (1 - 0.80)x

⇒ 0.20x

⇒ (20/100)x

The expressions that are the result of decreasing x by 80% will be (1 - 0.80)x, x - (80/100)x, and (20/100)x. Then the correct options are A, C, and E.

Hi there,

The formula depends on what shape you are dealing with. There is no way to determine what formula you need without knowing what type of figure you are dealing with.

Answer:

1. Square, 10in x 8in, 160in^2

2. Each surface has an area of 80in^2

Step-by-step explanation:

1. Rectangle is the shape of each cut surface which is 10in by 8 in. Since the block was already painted with glitter, she needs to paint both sides of the cut surface only, 2*8in * 10in = 160in^2.

2. Each cut will have a surface area of 10in * 8in = 80in^2
