What is the volume of the die?

Answer:

if lines are parralel then corresponding angles are congruent and alternate exterior angles are congruent. if lines are parralel, them same side interior angles are suplementary and same side exterior angles are suplementary

Answer:

When two lines are crossed by another line (called the Transversal): Alternate Exterior Angles are a pair of angles on the outer side of each of those two lines but on opposite sides of the transversal. In this example, these are two pairs of Alternate Exterior Angles: a and h.

Answer:

1. independent variable

2. dependent variable

3. control group

Step-by-step explanation:

Independent variables are the factors in the experiment that are being modified to discover some sort of result.

Dependent variables are those that change because of the independent variable; they're also the ones that are measured in the experiment.

The control group is a group that undergoes the same exact procedure as the experimental group(s) do, but without the independent variable; it is to make sure that the different results aren't due to environmental factors.

Here, because Hannah is changing the amount of fertilizer in the plants (none or a specific amount), the presence of fertilizer is the independent variable. Since the heights of the plants will likely change due to the presence of fertilizer, height is the dependent variable. And, finally, the pots without fertilizer undergo the same procedure but without the independent variable, or the fertilizer, so it's the control group.

Hope this helps!

Answer:

The presence of fertilizer in the soil is the independent variable

The height of the tomato plants is the dependent variable

The pots without fertilizer form the control group

Step-by-step explanation:

She has divided the pots into 2 groups of 10 each:

1) experimental group

2) control group

She can decide the amount of fertiliser so that's an independent variable

What's she's observing are the heights which she can't control so heights is the dependent variable

Answer:

The Sun's diameter is [tex]1.075\times 10^2[/tex] times the Earth's diameter.  

Step-by-step explanation:

We are given the following in the question:

Sun's diameter = 860,000 miles

Earth's diameter = 8000 miles

Comparison of Sun's and Earth's diameter:

[tex]\dfrac{\text{Sun's Diameter}}{\text{Earth's Diameter}}\\\\=\dfrac{860000}{8000}\\\\=\dfrac{8.6\times 10^{5}}{8\times 10^3}\\\\=1.075\times 10^2[/tex]

Thus, the Sun's diameter is [tex]1.075\times 10^2[/tex] times the Earth's diameter.

Answer:

An acute triangle

Step-by-step explanation:

All of the angles are less than 90 degrees

With the given angles of 80, 40, and 40 degrees, a triangle can be constructed because they sum up to 180 degrees. Since all the angles are less than 90 degrees, the triangle formed will be an acute triangle (option A).

The question is to determine what type of triangle will be constructed using the given angles of 80 degrees, 40 degrees, and 40 degrees. The sum of the angles in any triangle must equal 180 degrees. Given the angles provided, if we add them up (80 + 40 + 40), we get exactly 180 degrees. This confirms that a triangle can indeed be constructed with these angles.

Furthermore, since all the given angles are less than 90 degrees, this means each angle is acute. Therefore, a triangle with all acute angles is known as an acute triangle (option A). Hence, the triangle that will be constructed with the given angles is an acute triangle.

The required total weight of the potato and onion is given as  5.79 Kg.

As given in the question, the potatoes beth brought weighed 3 kilograms and 420 grams. Her onions weighed 1,050 grams less than the potatoes.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
Weight of the potatoes = 3 + 0.420 = 3.420 Kg
Weight of the onion  = weight of potato - 1.050
Weight of onion = 3.420 - 1.050
weight of onion = 2.370 Kg
Total weight = 3.42 + 2.37 = 5.79 Kg

Thus, the required total weight of the potato and onion is given as  5.79 Kg.

#SPJ5

a) 9.33$

b) 1.33$

Step-by-step explanation:

a)

To solve the problem, let's call

[tex]m[/tex] = the money that Bella has at the beginning

[tex]d=[/tex] the price of a dictionary

[tex]b=[/tex] the price of one book

[tex]j=\$7[/tex] the price of the journal

Here, Bella spent 4/7 of her money to buy a dictionary and 3 books, so

[tex]\frac{4}{7}m=d+3b[/tex] (1)

Then she spent 1/6 of the remainder (which is [tex]\frac{3}{7}m[/tex]) to buy the journal so

[tex]\frac{3}{7}m=j=7[/tex] (2)

So from this second equation we can find m, the money that she has at the beginning:

[tex]m=\frac{7}{3}\cdot 7 =\frac{49}{3}=\$16.3[/tex]

So the amount that she spent for the dictionary + the 3 books is

[tex]\frac{4}{7}m = \frac{4}{7}\cdot \frac{49}{3}=\frac{28}{3}=\$9.33[/tex]

b)

Here, we are told that

3/8 of the cost of the dictionary was the same as 1/2 of the total cost of 3 books

Which can be rewritten as an equation as follows:

[tex]\frac{3}{8}d=\frac{1}{2}(3b)[/tex]

This means that we can rewrite the cost of the dictionary by re-arranging this equation as:

[tex]d=\frac{8}{3}\cdot \frac{1}{2}(3b) =4b[/tex]

Substituting into eq.(1) of part a),

[tex]\frac{4}{7}m=4b+3b\\\frac{4}{7}m=7b[/tex]

And from this, we can find b, the cost of each book:

[tex]b=\frac{1}{7}\cdot \frac{4}{7}m=\frac{4}{49}\cdot \frac{49}{3}=\frac{4}{3}=\$1.33[/tex]

a. She spent on the dictionary and 3 books is $8.

b. The cost of each book is $2.

a) First, let's find out how much Bella spent on the dictionary and 3 books.

Given that Bella spent 4/7 of her money on the dictionary and 3 identical books, this means she spent 1 - 4/7 = 3/7 of her money on other items.

Next, she spent 1/6 of the remaining money on a journal, which cost $7. So, 1/6 * 3/7 * Total money = $7.

To find the total money she had, we'll multiply $7 by 6/1 * 7/3 = $14.

Now, let's find out how much she spent on the dictionary and 3 books. She spent 4/7 * $14 = $8 on them.

b) Now, let's find out how much each book costs.

Given that 3/8 of the cost of the dictionary is the same as 1/2 of the total cost of 3 books, we set up the equation:

(3/8) * Cost of Dictionary = (1/2) * Total cost of 3 books.

Let's denote the cost of each book as x.

So, (3/8) * Cost of Dictionary = (1/2) * 3x.

To solve for x, first find the cost of the dictionary. From part a, we know the cost of the dictionary is $8.

Substitute $8 into the equation: (3/8) * 8 = (1/2) * 3x.

Simplify: 3 = (3/2) * x.

Now, isolate x: x = 3 * 2/3 = $2.

Therefore, each book costs $2.

Answer:

They are 261.96 meters apart.

Step-by-step explanation:

From the question, considering a North, East, South and west pole, Gustavo ran 23° above the east horizontal, while Aiden ran 33° below the east horizontal.

Thus, the total angle between them is 23 + 33 = 56°.

Therefore, let the distance between them be c and we can calculate that using the cosine law. Thus,

c² = a² + b² – 2ab cos θ

Where a and b are distances travelled respectively by Gustavo and Aiden. While θ is the angle between them.

Thus,

c² = 300² + 250²– 2(300) (250)cos 56

c² = 90000 + 62500 - 83878.9355

c² = 68621.0645

c = √68621.0645

c = 261.96 m

They are 261.96 meters apart.

Answer:

20%

Step-by-step explanation:

1.6:8*100 =

(1.6*100):8 =

160:8 = 20

Now we have: 1.6 is what percent of 8 = 20

Question: 1.6 is what percent of 8?

Percentage solution with steps:

Step 1: We make the assumption that 8 is 100% since it is our output value.

Step 2: We next represent the value we seek with $x$.

Step 3: From step 1, it follows that $100\%=8$.

Step 4: In the same vein, $x\%=1.6$.

Step 5: This gives us a pair of simple equations:

$100\%=8(1)$.

$x\%=1.6(2)$.

Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS

(left hand side) of both equations have the same unit (%); we have  

{100\%}{x}={8}{1.6}

Step 7: Taking the inverse (or reciprocal) of both sides yields

{100\%}={1.6}{8}

x=20

Therefore, $1.6$ is $20 of $8$.

Amount deposited into Lou's 401(k) each payday is $119.665

Step-by-step explanation:

Here we have gross income annual $41028

Payment frequency = Every two weeks

Number of payments (Pay days per annum)  = 12 × 2 = 24 payments annually

Amount payed on pay day = $41028/24 = $1709.5

Amount deducted from Lou's paycheck on payday = 4% of Pay = 0.04×$1709.5

∴ Amount deducted from Lou's paycheck on payday = $68.38

Amount employer matches = 3% of pay = 0.03 × $1709.5 = $51.285

Therefore, amount deposited into Lou's 401(k) each payday = $68.38  + $51.285

Amount deposited into Lou's 401(k) each payday = $119.665.

Step-by-step explanation:

Given:

The given expression is [tex]\frac{b^{-2}}{a b^{-3}}[/tex]

Let us assume that [tex]a \neq 0, b \neq 0[/tex]

We need to determine an expression that is equivalent to the expression [tex]\frac{b^{-2}}{a b^{-3}}[/tex]

Equivalent expression:

The equivalent expression can be determined by solving the given expression.

Hence, applying the exponent rule, [tex]\frac{x^{a}}{x^{b}}=x^{a-b}[/tex]

Thus, we get;

[tex]\frac{b^{-2}}{a b^{-3}}=\frac{b^{-2-(-3)}}{a}[/tex]

Subtracting the numbers, we get;

[tex]\frac{b^{-2}}{a b^{-3}}=\frac{b}{a}[/tex]

Thus, the equivalent expression is [tex]\frac{b}{a}[/tex]

Answer:

Her account balance after 3 years is $4,246.71

Step-by-step explanation:

In this question, we are tasked with calculating what Hannah's account balance will be after 3 years and the error she made in her calculations

Mathematically, to calculate the account balance after 3 years, we use the formula for the compound interest as follows.

Mathematically, the amount A earned on a compound interest is calculated as

A = P[tex](1+r/n)^{nt}[/tex]

where A is the account balance after the number of years which is what we want to know

P is the initial amount invested which is $4000

r is the interest rate which is 2%(2/100 = 0.02) according to the question

n is the number of times interest is compounded per year which is 4(quarterly means every 3 months)

t is the number of years which is 3

We plug the values into the question;

A = 4000(1 + 0.02/4)^(3)(4)

A = 4000(1+0.005)^12

A = 4000(1.005)^12

A = $4,246.71

P.S ; I do not see Hannah's calculation and as such I cannot spot where she made the error in her calculations

Final answer:

Hannah made a calculation error; the correct balance after 3 years at 2% interest compounded quarterly on a $4000 investment is approximately $4248.71.

Explanation:

The student has incorrectly calculated the future value of a $4000 investment at 2% interest, compounded quarterly. The accurate calculation involves using the compound interest formula:

P = P0 (1 + r/n)nt

Where:

P is the future value of the investment.

P0 is the principal amount ($4000).

r is the annual interest rate (2%, or 0.02).

n is the number of times interest is compounded per year (4, since it is quarterly).

t is the time the money is invested for (3 years).

Plugging in the values we get:

P = $4000 (1 + 0.02/4)4*3

After solving, we get P = $4000 * (1 + 0.005)12 ≈ $4000 * 1.061677812

Hence, the account balance after 3 years would be approximately $4248.71, not $4244.83 as Hannah initially thought.
