Month 1: 239 cars sold
Month 2: 324 cars sold
Do we have an increase or a decrease in sales and what percentage?

Answer:

The decimal point moves two places to the left when you rewrite the percentage as a decimal. When you rewrite the decimal as a percentage you move the decimal point two places to the right.

Answer:

explanation will answer.

Step-by-step explanation:

To convert this fraction to a decimal, just divide the numerator (35) by the denominator (64). So, 35 / 64 = 35 ÷ 64 = 0.546875. Approximated Values: 35 / 64 = 0.5 rounded to 1 significant figure. 35 / 64 = 0.55 rounded to 2 significant figures. 35 / 64 = 0.547 rounded to 3 significant figures.

Answer:

its B

Step-by-step explanation:

because if you flip e to the other side of the y-axis you'll get (2,4) and do the same with the letters and that's your answer.

Answer:

B.  C'(3 , 0) , D'(7 , 1) , E'(2 , 4)

Step-by-step explanation:

reflecting the point A(x , y) across the y-axis gives us the point A'(-x , y)

Then

The image of E(-2 , 4) is E'(2 , 4)

The image of C(-3 , 0) is C'(3 , 0)

The image of D(-7 , 1) is D'(7 , 1)

Therefore

The correct answer is option B.

The measure of the angles m∠1, m∠2 and m∠3 are 145°, 35° and 35° respectively.

An equation is an expression that shows the relationship between two or more numbers and variables.

m∠2 = m∠4 = 35° (corresponding angles are equal)

m∠2 = m∠3 = 35° (corresponding angles are equal)

m∠1 + m∠3 = 180° (base angles are supplementary)

m∠1 + 35 = 180

m∠1 = 145°

The measure of the angles m∠1, m∠2 and m∠3 are 145°, 35° and 35° respectively.

Answer:

10.8 pages must be prepared

Step-by-step explanation:

We first have to figure out how many words Julie would be able to say in 45 minutes. Since she can say 120 words per minute, she can speak 120*45 or 5400 words total.

We also know that Julie can write 500 words per page. Since she has 5400 words total, she needs to prepare 10.8 pages total (5400 divided by 500). If you are looking for a whole number answer, Julie needs at least 11 pages to write her complete speech.

Answer:

The number of pages she should prepare is 10.8 pages.

Step-by-step explanation:

Given:

Julie wants to give a 45 -minute speech, and she speaks 120 words per minute.

Her written notes contain 500 words per page.

Find:

The number of pages she should prepare

Step 1 of 1

We will set up a conversion factor:

number of pages [tex]=(45$ minutes $) \cdot \frac{120 \text { words }}{1 \text { minutes }} \cdot \frac{1 \text { pages }}{500 \text { words }}$[/tex]

[tex]$$\begin{aligned}&=\frac{45 \cdot 120}{500} \text { pages } \\&=10.8 \text { pages. }\end{aligned}$$[/tex]

Answer:

It takes the hose 300 hours to fill the pool

Step-by-step explanation:

The hose can fill the pool at a rate of 0.5 gallons per second, which means that it can fill the pool at a rate of 1 gallon per 2 seconds. It needs to fill 9000 gallons of water, so assuming the ratio remains 1:2, it takes the hose 18000 (9000*2) seconds to fill the pool completely.

However, it is important to note that we have to answer in terms of hours. There are 60 seconds in an hour, so 18000 seconds is equal to 300 hours (18000/60).

Answer:

If the pool's capacity is 9,000 gallons the number of hours it takes for the hose to completely fill an empty pool is 5 hours.

Step-by-step explanation:

Given:

A hose fills a swimming pool at a rate of 0.5 gallons per second.

If the pool's capacity is 9,000 gallons, we have to find the number of hours it would take for the hose to completely fill an empty pool.

Step 1 of 1

Do a basic conversion problem:

time in seconds[tex]$=9000$ gallons $\cdot \frac{1 \text { seconds }}{0.5 \text { gallons }}$[/tex]

[tex]$$\begin{aligned}&=\frac{9000}{0.5} \text { seconds } \\&=18000 \text { seconds }\end{aligned}$$[/tex]

We can also convert seconds to hours using conversion factors. This gives

[tex]$$\begin{aligned}18000 \text { seconds } &=(18000 \text { seconds }) \cdot \frac{1 \text { minute }}{60 \text { seconds }} \cdot \frac{1 \text { hour }}{60 \text { minutes }} \\&=\frac{18000}{60 \cdot 60} \text { hours } \\&=5 \text { hours }\end{aligned}$$[/tex]

Answer:

Step-by-step explanation:

$7.45 = 100g

x = 3kg( 3 × 1000) = 3000g

∵ $7.45 = 100g

   x        = 3000g

(100 × x) = (7.45 ×  3000)

100x = 22350

100x/100 = 22350/100

x  = $223.5

Answer:what graph?

Step-by-step explanation:

if we cant see the graph then we cant answer lol

Based on the image attached of the graph, the points that show equivalent ratios that would also be on the graph are option A and D which are: (6,18)  (1,3).

Note that: [tex]\frac{x}{y}[/tex]

=[tex]\frac{3}{9}[/tex]

= 1/3

So when you use 1/3 to compare all the options given, you will see that only option A and D  is equal to the value given.

So if a person can write that  we got  1 fish and we needs 3 gallons and when a person  make a point on the line, it will be (1,3).

The other equivalent fraction is known to be 6/18. When a person multiply the numerator and denominator by 2, the value that will be obtained is:

[tex]\frac{3 x 2 }{9 x 2}[/tex]   = 6/18.

So therefore, Based on the image attached of the graph, the points that show equivalent ratios that would also be on the graph are option A and D which are: (6,18)  (1,3).

Answer:

84°

Step-by-step explanation:

The circle has five central angles that together equal to 360°.

55° + 37° + 96° + 88° = 276°

Hence, to find the fifth central angle, we have to subtract 276° from 360°.

360° - 276° = 84°

The degree measure of the last central angle is 84°.

Answer:

On comparing the center i.e. mean we get that the sports magazine 19 uses more words than a political magazine 18 but they are almost the same because their difference is only 1. The variance of sports magazines 5.8 is greater than the variance of political magazines 5.2. We cannot use this to make a valid comparison about the magazines to a magazine the content matters or maybe the number of readers matters not the number of word count.

Step-by-step explanation:

Given: The number of words per sentence in a sports magazine to the number of words per sentence in a political magazine. The data represent random samples of 10 sentences in each magazine.

Sports magazine [tex]$$9,21,15,14,25,26,9,19,22,30$$[/tex].

Political magazine [tex]$$31,22,17,5,23,15,10,20,20,17$$[/tex].

To compare the samples using measures of center and variation.

Step 1 of 2

The mean of the words of sports magazine is [tex]\begin{aligned}(9+21+15+14+25+&26+9+19+22+30) \times \frac{1}{10} \\&=\frac{190}{10} \\&=19\end{aligned}[/tex]

The mean of the words of the political magazine is [tex]\begin{aligned}&(31+22+17+5+23+15+10+20+20+17) \times \frac{1}{10}\\&=\frac{180}{10}\\&=18\end{aligned}[/tex]

On comparing the center i.e. mean we get that the sports magazine uses more words than a political magazine.

Step 2 of 2

Variation of sports magazine is [tex]=\frac{1}{10}\times(|19-9|+|19-21|+|19-15|+|19-14|+|19-25|+|19-26|+|19-9|+|19-19|+|19-22|+|19-30|)$$\\ $$=\frac{1}{10}\times(10+2+4+5+6+7+10+0+3+11)$$\\$$=\frac{1}{10}\times58$$\\$$=5.8$$[/tex]Variation of the political magazine is \end{tabular}

[tex]=\frac{1}{10}\times(|18-31|+|18-22|+|18-17|+|18-5|+|18-23|+|18-15|+|18-10|+|18-20|+|18-20|+|18-17|)$$\\ $$=\frac{1}{10}\times(13+4+1+13+5+3+8+2+2+1)$$\\ $$=\frac{52}{10}$$\\ $$=5.2$$[/tex]

The variance of sports magazines is greater than the variance of political magazines.

We cannot use this to make a valid comparison about the magazines to a magazine the content matters or maybe the number of readers matters not the number of word count.
