Answer:

175.1

Step-by-step explanation:

Find the area of the semicircle:

(pi • radius²) / 2. [Radius is half of diameter]

(3.14 • 4²) / 2

(3.14 • 16) / 2

(50.24) / 2

25.12

Find the area of the parallelogram:

(base • height)

(30 • 5)

150

Add the areas of both shapes to get total area

25.12 + 150 = 175.12, round to the nearest tenths, 175.1

Hope this helps!

d >= 235 miles

Step-by-step explanation

Since you that he needs to drive at LEAST 235, you know that he can drive exactly 235 miles or more than 235 miles. That means you would need to use the greater than or equal to sign.

Answer:

Step-by-step explanation:

180-37=143

Answer:

The correct solution is "$1618.79".

Step-by-step explanation:

The given values are:

Home price,

= $300,000

Down payment,

= 10%

Mortgage,

= $270,000

Rate,

r = 6%

Time,

t = 30 years

As we know,

⇒ [tex]PV=P[\frac{1-(1+r)^{-n}}{r} ][/tex]

On substituting the values, we get

⇒ [tex]270 000= P[\frac{1-(1+\frac{6}{1200} )^{-12\times 30}}{\frac{6}{1200} } ][/tex]

⇒          [tex]P=1618.79[/tex] ($)

Answer:

312,764.40

Step-by-step explanation:

We previously determined that you will make monthly payments of $1,618.79 for 30 years to pay off the loan. You are paying $1,618.79 per month for 360 months.

1,618.79×360−270,000=312,764.40

You are paying a total of  $312,764.40 in interest over the life of the loan.

Answer:

Z=8 is the answer

Step-by-step explanation:

first, you add 8 to both sides which leaves you with 5z=40. then after that you divide both sides by 5 which leaves you with 5/5z = 40/5. then buy dividing 5 by 5 its leaves you with 1 which is equal to z because blank variables equal 1. On the other side if the equation 40 by 5 is 8 so that leaves you with z=8

Step-by-step explanation:

[tex] \tt{5z - 8 = 32}[/tex]

We want to remove the 8 first.

Step 1 : Since the original equation is minus 8 , we are going to use the opposite operation and add 8 to both sides.

⟶ [tex] \tt{5z - 8 + 8 = 32 + 8}[/tex]

Simplify -8 + 8 = 0 on the left. 32 + 8 = 40 on the right. Then we need to think about how to remove the coefficient 5.

⟶ [tex] \tt{5z = 40}[/tex]

Step 2 : Since the opposite of multiplication is division , we are going to divide both sides by 5.

⟶ [tex] \tt{ \frac{5z}{5} = \frac{40}{5}} [/tex]

Simplify. 5 / 5 = 1 on the left. 40/5 = 8 on the right. So , our answer is z = 8.

⟶ [tex] \tt{z = 8}[/tex]

[tex] \pink{ \boxed{ \boxed{ \text{Our \: final \: answer : \boxed{ \underline{ \tt{z = 8}}}}}}}[/tex]

Hope I helped ! ♡

Answer:

Step-by-step explanation:

13.3% of population = 30.7×10⁶

0.133 × population = 30.7×10⁶

population =  30.7×10⁶/0.133 ≅ 230.8×10⁶

population ≅ 230.8 million

The total U.S. population is approximately 23 million people.

Given the following data:

To calculate the total U.S. population:

How to solve a word problem.

In this exercise, you're required to determine the total number of people that make up U.S. population, if there are 30.7 million Americans in a which make up 13.3% of the total population.

Mathematically, this is given by this expression:

[tex]30.7 \times 10^6 = \frac{13.3}{100} \times T\\ \\ 30.7 \times 10^7=13.3T\\ \\ T=\frac{30.7 \times 10^7}{13.3} [/tex]

T = 23,082,706.8 ≈ 23 million people.

Answer:

The expected net gain to the player for one play is -$0.0526.

Step-by-step explanation:

To find the expected net gain, we multiply each outcome by its probability:

Player wins:

Earns $35.

1 out of 38 numbers, so probability 1/38.

Player loses:

Loses $1.

37 out of 38 numbers, so probability 37/38.

Expected value:

[tex]\frac{1}{38} \times 35 - \frac{37}{38} \times 1 = -\frac{2}{38} = -0.0526[/tex]

The expected net gain to the player for one play is -$0.0526.

C 0759, 1518

Step-by-step explanation:

The numbers which represent the first 2 students selected is the option D.) 0759, 1019.

Random number table are a table of numbers arranged in an unpredictable sequence. These tables are used to select a random sample in certain situations.

We have the line in the random table as,

24000  75983  62200  91518  10198  88936

There are 1020 students in total.

So we have to select four digit numbers of the sequence 0001, 0002, ..........., 1019, 1020.

Any number which is not included in this interval will not be selected.

From the reference line given, the four digit numbers are,

2400, 0759, 8362, 2009, 1518, 1019, 8889, ...

From this line, mark the numbers included in our interval from 0001 to 1020.

The numbers are 0759 and 1019. Other numbers are not included in our required interval.

Hence the first 2 students will represent as the numbers 0759 and 1019.

Answer:73-10

Step-by-step explanation:

Answer:

Since the frequency of the numbers vary, the students are not effective at generating random numbers.

Step-by-step explanation:

If they were effective, all the numbers should have around the same probability of being generated.

Between 1 and 20 there are 20 numbers, so the frequency of each number should be around 100%/20 = 5%.

Since the frequency of the numbers vary, the students are not effective at generating random numbers.

Answer:

15% plus 40% would be 65%. its just what is left of 100%. The answer is 35%

Step-by-step explanation:

this is really easy. Try harder.

Answer:

525

Step-by-step explanation:

Add the available percent of stamps. 40% + 15%= 65%, a percent is over 100, so 65/100 of 1500 basically means 65/100 x 1500 which equals to 525.

Answer:

[tex]3+(-7)+\frac{2}{5}+(-\frac{1}{5})[/tex]

Step-by-step explanation:

We are given that an expression

[tex]3\frac{2}{5}+(-7\frac{1}{5})[/tex]

We have to find the expression which shows the sum of integer and fractional parts.

The given expression can be written as

[tex]3+\frac{2}{5}+(-7-\frac{1}{5})[/tex]

Now, adding integers

[tex](3+(-7)+\frac{2}{5}+(-\frac{1}{5})[/tex]

Now, adding fraction parts we get

[tex]3+(-7)+(\frac{2}{5}+(-\frac{1}{5}))[/tex]

Hence, the expression which shows the given expression as a sum of integers and fractional parts is given by

Second answer down

Answer:

Speed of wind = 23.63 miles per hour

Plane speed in still air = 260 miles per hour

Step-by-step explanation:

Given:

Time taken with wind = 5 hour

Time taken against wind = 6 hour

Assume;

Speed of wind = s

So,

Speed of Plane with wind = (260 + s) miles per hour

Speed of Plane against wind = (260 - s) miles per hour

Distance = speed x time

So,

(260 + s)5 = (260 - s)6

1,300 + 5s = 1,560 - 6s

11s = 260

s = 23.63 miles per hour

Speed of wind = 23.63 miles per hour

Plane speed in still air = 260 miles per hour
