the perimeter of a rectangle is (8x + 7y) feet, give two possible dimensions of the rectangle

please help ?? ​

Answer:

- 7/11 = 0.636363

- 18/25 = -0.72

Answer:

21%

Step-by-step explanation:

First find the whole, the total number of attendees:

714 \text{ home} + 2686 \text{ visiting} = \color{orange}{3400} \text{ total attendees}

714 home+2686 visiting=3400 total attendees

Method 1: Set up a proportion

Set up an equation of the form:

\frac{\color{red}{\text{part}}}{\color{orange}{\text{whole}}}=

whole

part

​  

=

\,\,\frac{\color{blue}{\text{percent}}}{100}

100

percent

​  

Assign the variable xx to the unknown value:

\color{blue}{x}=

x=

\,\,\color{blue}{\text{percent}}

percent

The question asks what \textit{percent}percent of all the attendees is 714

Substitute the known values with the numbers given in the problem, and the unknown value with xx:

\frac{\color{red}{714}}{\color{orange}{3400}}=

3400

714

​  

=

\,\,\frac{\color{blue}{x}}{100}

100

x

​  

Solve for xx:

100\cdot\color{red}{714}=

100⋅714=

\,\,\color{orange}{3400}\cdot\color{blue}{x}

3400⋅x

Cross multiply

\frac{71400}{3400}=

3400

71400

​  

=

\,\,\frac{3400x}{3400}

3400

3400x

​  

Divide both sides by 100

\color{blue}{21\%}=

21%=

\,\,\color{blue}{x}

x

Simplify

Method 2: Find percent directly

\text{Find \(714\) out of \(3400\) as a decimal:}

Find 714 out of 3400 as a decimal:

\frac{\color{red}{714}}{\color{orange}{3400}}=

3400

714

​  

=

\,\,0.21

0.21

\text{Convert decimal to percent:}

Convert decimal to percent:

0.21\times100=

0.21×100=

\,\,\color{blue}{21\%}

Answer: [tex]2.78m^{2}[/tex]

Step-by-step explanation:

given data:

height of the statue = 80m.

base of the statue = [tex]625m^{2}[/tex].

scale of the statue replica = 1:15.

solution:

[tex]= 1:15^{2} \\\\\= 1:225\\\\[/tex]

[tex]= \frac{625m^{2} }{225}[/tex]

= [tex]2.78m^{2}[/tex]

the area of the replica is [tex]2.78m^{2}[/tex]

Answer:

2.78 m^2 is the correct answer. :)

Answer:

23[tex]\frac{1}{3}[/tex]m/s

Step-by-step explanation:

We can change the km to m first. 1km = 1000m.

84km/h = 84 000m/h

Then, we can change the h to s. 1h = 3600s.

84 000m/h = 23[tex]\frac{1}{3}[/tex]m/s

Answer:

2 1/3 ; 9 1/3

Step-by-step explanation:

Given that:

Outside temperature increases by 3 1/2 degrees every 1 1/2 hours

The rate per hour of temperature increase will be :

Let rate per hour = x

3 1/2 = 1 1/2

x = 1

Cross multiply :

1 1/2 * x = 3 1/2 * 1

3x/2= 7/2

Multiply both sides by 2/3

3x/2 * 2/3 = 7/2 * 2/3

x = 14/ 6

x = 2 2/6

x = 2 1/3

Hence, outside temperature increases at the rate of 2 1/3 degrees per hour.

2.) Temperature increase after 4 hours :

(Temperature rate per hour * number of hours)

(2 1/3) * 4

(7/3) * 4

28 / 3

= 9 1/3

Hence, temperature increase after 4 hours = 9 1/3

2 1/3 ; 9 1/3

Step-by-step explanation:

Given that:

Outside temperature increases by 3 1/2 degrees every 1 1/2 hours

The rate per hour of temperature increase will be :

Let rate per hour = x

3 1/2 = 1 1/2

x = 1

Cross multiply :

1 1/2 * x = 3 1/2 * 1

3x/2= 7/2

Multiply both sides by 2/3

3x/2 * 2/3 = 7/2 * 2/3

x = 14/ 6

x = 2 2/6

x = 2 1/3

Hence, outside temperature increases at the rate of 2 1/3 degrees per hour.

2.) Temperature increase after 4 hours :

(Temperature rate per hour * number of hours)

(2 1/3) * 4

(7/3) * 4

28 / 3

= 9 1/3

Hence, temperature increase after 4 hours = 9 1/3

Step-by-step explanation:

Answer:

20 minutes

Step-by-step explanation:

34 times 45 secs equals 1190 secs,

since there is 60 secs in one minute you would divide,

1190/60 = 19.8333.. mins or 19 mins and 50 secs

In multiplication, the exponents add up.

5.5²=5¹.5²=5³

Note:

In the extraction ,the exponents remove.

5¹⁰÷5³=5⁷

Answer:

5³

Step-by-step explanation:

Using the rule of exponents

[tex]a^{m}[/tex] × [tex]a^{n}[/tex] = [tex]a^{(m+n)}[/tex]

Given

5 × 5²

= [tex]5^{1}[/tex] × 5²

= [tex]5^{(1+2)}[/tex]

= 5³ ← in index form

= [ 125 ]

Answer:

0%

Step-by-step explanation:

0% because there are no red apples in a bag of green apples.

Therefore it is impossible to pick a red apple.

Answer:

Slope is often denoted by the letter m; there is no clear answer to the question why the letter m is used for slope, but its earliest use in English appears in O'Brien (1844) who wrote the equation of a straight line as "y = mx + b" and it can also be found in Todhunter (1888) who wrote it as "y = mx + c".

Answer:

23

Step-by-step explanation:

Answer: 25%

Step-by-step explanation:

Given: A rectangle has length 4 inches and width 2 inches.

Area = Length x width

= 4 inches x  2 inches

= 8 square inches

If length is reduced by 50% , then length [tex]=0.5\times4=2\text{ inches}[/tex]

If width is reduced by 50% , then length [tex]=0.5\times2=1\text{ inch}[/tex]

Reduced area = (reduced length) x (reduced width)

= 2 inches x 1 inch

= 2 square inches

The percentage of the area of the rectangle be reduced :-

[tex]\dfrac{\text{Reduced area}}{\text{Original area}}\times100 \\\\=\dfrac{2}{8}\times100\% \\\\=25\%[/tex]

Hence, the percent of the area of the rectangle be reduced = 25%

Section 1

Answers:

-----------------------------

Explanation:

The abbreviation d.p. means decimal places

When rounding to 2 decimal places, we look at the digit in the third decimal place value slot (thousandths place). If the value is 5 or larger, then we round up. In the case of 1.6962, the second 6 tells us to round 1.69 up to 1.70

Something like 0.4247 does not round up because that second 4 is not 5 or larger. So we just are left with 0.42

The same logic applies to three decimal places, but you'll look in the fourth slot this time.

===================================================

Section 2

Answers:

-----------------------------

Explanation:

Recall that for a number like 32500, the 0s are not significant. This is because we can write that as 3.25 * 10^4 to convey the same idea. The only significant figures are 3, 2 and 5.

So when rounding 32549 to 3 sig figs, we just pick on the three left most values, and the rest go to 0. The 325 does not round up to 326 because the '4' isn't 5 or larger. Put another way: 32549 is closer to 32500 than it is to 32600

When rounding 909520 to three sig figs, it turns into [tex]91\overline{0}000[/tex]. The line over the first '0' tells us that zero is significant. Without this bar, the zero would be considered not to be significant. The 9095 is closer to 9100 than it is to 9000, so that's why we rounded up.

Answer:

he saved about 2300$

Step-by-step explanation:

Answer: $54.35

Step-by-step explanation:

If each one of the 15 students raises the same amount, let's define this amount by the variable X, then the total amount they will collect is 15 times X, or:

15*X

And the minimum amount they need to collect is $800

Then we will have the inequality:

15*X ≥ $800

Now we can divide both sides by 15 to get the minimum amount that each student needs to raise:

(15*X)/15 ≥ $800/15

X ≥ $54.33...

Where we should round up the right number to $54.35, because we can not have a $0.0333... and if we round down, they would collect less than $800.

Then the inequality is:

X ≥ $54.35

This means that the minimum amount that each one of the 15 students needs to collect is $54.35
