Answer:

the answer 117

Step-by-step explanation:

The 234 divided by 2 is 117.

To calculate 234 divided by 2, we perform the division operation step by step.

Step 1: Divide 234 by 2.

234 ÷ 2 = 117

The result of 234 divided by 2 is 117. When you divide 234 by 2, you are essentially dividing 234 into two equal parts. Each part contains 117. This can be confirmed by performing the calculation:

234 ÷ 2 = 117

Therefore, 234 divided by 2 is 117. Division is the inverse operation of multiplication, and in this case, we find that 234 is evenly divisible by 2, resulting in a whole number quotient of 117.

The increase rate per year is 0.

Calculus is a branch οf mathematics that deals with the study οf rates οf change and hοw things change οver time. It has twο main branches, differential calculus which studies instantaneοus rates οf change, and integral calculus which deals with accumulatiοn and area.

here given equatiοn fοr the value οf the cοmic bοοk is:

V(y) = 0.20y + 1.50

where y is the number οf years since it was released.

Tο find the rate οf increase per year fοr the value οf the cοmic bοοk, we can take the derivative οf V(y) with respect tο y:

dV/dy = 0.20

This means that the value οf the cοmic bοοk increases by 0.20 dοllars per year.

Tο find the rate οf increase per year fοr the initial value οf the cοmic bοοk, we need tο lοοk at the y-intercept οf the equatiοn fοr V(y). The y-intercept is the value οf V when y is 0, which is:

V(0) = 0.20(0) + 1.50 = 1.50

Therefοre, the initial value οf the cοmic bοοk is $1.50.

Tο find the rate οf increase per year fοr the initial value, we can calculate the derivative οf the initial value with respect tο y, which is:

d/dy (1.50) = 0

This means that the initial value οf the cοmic bοοk dοes nοt change with respect tο time, sο its rate οf increase per year is 0.

Answer:

85

Step-by-step explanation:

The sum of the measures of the interior angles of a triangle is 180 deg.

x + 52 + 43 = 180

x + 95 = 180

x = 85

Answer: 85

The angles in a triangle add up to 180 degrees

180 - 52 - 43 = 85

x = 85 degrees

If only half the machines are working at the same rate as before, the order will be finished in 64 hours.

When the four big fridges were working simultaneously, they were able to finish the order in 32 hours.

With only half of these fridges, they will only be half as fast. This means that they will complete the order in double the time:

= 32 x 2

= 64 hours

In conclusion, the order will be completed in 64 hours.

Step-by-step explanation:

The perpendicular line *always* has a slope of the negative reciprocal. Your given line has a slope of -5, so the perpendicular slope is -1/(-5) = 1/5.

Use the point-slope form of a general line to find the equation.

(y - y_1) = m * (x - x_1)

y - 7 = (1/5) * (x - 15)

Answer:

  30 miles

Step-by-step explanation:

The Law of Sines is used for this purpose. The angle at R is the difference ...

  180° -(23° +34°) = 123°

Then the length r satisfies ...

  ST/sin(R) = RT/sin(S)

  ST/sin(123°) = (20 mi)/sin(34°)

  ST = (20 mi)sin(123°)/sin(34°) ≈ 30.00 mi

The length of r or ST is 30 miles.

Use the quadratic formula where -15 = a, 7 = b, 23 = c:  [tex]\frac{-b +- \sqrt{b^2 - 4ac}}{2a}[/tex]

Plug in the values: [tex]\frac{-7 +- \sqrt{7^2 - 4(-15)(23)}}{2(-15)}[/tex]

And get: [tex]\frac{-7 +- \sqrt{49 +1380}}{-30}[/tex]

Which simplifies to: [tex]\frac{-7 +- \sqrt{1429}}{-30} = (-7 + 37.8021163)/-30 OR (-7 - 37.8021163)/-30 = 30.8021163/30 OR -44.8021163/30[/tex]

Those are approximately 1 and -1.5

<5 = 105 degrees

Step-by-step explanation:

From the description given, since line l is parallel to m then <4 is alternate to <5 and two alternate angles are equal, if thst is the case

<4 = <5 (alternate angle)

Since <4 = 105 degrees, hence m<5 = 105 degrees

2^4*6^4 is the same as the expression which is equal to 20736

1. A kite has a width to length ratio of 4:5, so let the width be 4x and the length be 5x. We know that the length is 80 cm. 80 = 5x

Divide by 5.

16 = x.

Now, the width is 4x.

16 times 4 is 64.

The width is 64.

2. Find the unit rate for each juice. The unit rate is ml / dollar.

The first juice has a unit rate of 150 / 1.

The second has a unit rate of 500 / 1.75.

The third has a rate of 1000 / 4.

The fourth has a rate of 2000 / 7.25

Put all values into a calculator. (First: 150, Second: 285.714285, Third: 250, Fourth: 275.862068966)

Whichever one can buy the most ml for a dollar is the best buy.

In here, that is the SECOND rate, which is 1.75 for 500 ml.

She earns 3% commission on all her sales, so if s represents her sales, she'd earn .03s. Inhere, she sells $950 in total. That is her total sales.

So you plug $950 into the equation as s.

.03 (950) = 28.5

She earned $28.50.

Poor Maya!

3. You set it up in ratios. She needs 250 mL of milk for every 325 mL of pancake mix. 250 milk / 325 mix.

But she only has 225 mix.

So you set up 250 milk / 325 mix = M milk / 225 mix

As in all proportions, you cross multiply.

250 x 225 = 325 x M

56250 = 325M

Divide by 325 on both sides.

173.076923077 = M

She needs about 175 mL. The fourth choice.

4. There are a total of 1120 spectators, made of only home team fans and visiting team fans.

There is a total of 100% of people, and 80% are supporters of the home team, so to find the supporters of the visiting team you subtract 100% by 80%.

100 - 80 = 20.

So 20% of the spectators are supporters of visiting team. Now 20% of the total, and 20% = .20.

.20 x 1120 = 224

224 people are fans of the visiting team.

5. A 500-mL bottle of insect repellent has 22 mg of DEET, a chemical used to keep mosquitos away. The same insect repellent sells in 710-mL bottles. Which of the following proportions can be used to find the amount of DEET in the larger bottle? *

If a 500 mL bottle has 22mg of DEET, then 500ml / 22mg

So set up the equation 500 / 22 = 710 / x

Now, cross multiply.

500x = 710 times 22.

500x = 15620

Divide by 500.

x = 31.24

Other possible proportions are:

22 / x = 500 / 710

x / 22 = 710 / 500

22 / 500 = x / 710
