Answer:

15.6 ft

Step-by-step explanation:

Since the sails are similar then the ratios of corresponding sides are equal.

Comparing the shortest sides, that is

10 : 6 = 5 : 3

let the longest side be x, then using proportion

$\frac{26}{5}$ = $\frac{x}{3}$ ( cross- multiply )

5x = 78 ( divide both sides by 5 )

x = 15.6

The longest side is 15.6 ft

A rectangle has a length of (x + 4) centimeters and a width of 12x centimeters. If the perimeter is 26 centimeters, what is the

mars1129 [50]

Width of rectangle is 8.4 cm

Step-by-step explanation:

Length of rectangle = x+4

Width of rectangle = 12x

Perimeter = 26 cm

We need to find width of rectangle.

The formula used is:

$Perimeter=2(length+width)$

Putting values and finding x first:

$Perimeter=2(length+width)$

$26=2(x+4+12x)$

$26=2(13x+4)$

$26=26x+8$

$26-8=26x$

$26x=18$

$x=\frac{18}{26}$

$x=0.7$

So, value of x is 0.7

Now width= 12x = 12(0.7)

=8.4 cm

So, width of rectangle is 8.4 cm.

What addition statement does this show?

Anuta_ua [19.1K]

Answer:

D. –5.2 + (–6.4) = –11.6

Step-by-step explanation:

First, you can eliminate A and C because 5.2 is positive. Since the red arrow is pointing left, it indicates that the number (-5.2) is negative.

Then, you look at the second arrow, the green one. It is pointing left, so it would be -6.4.

I hope this helps :)

Learning Task 1: Read and analyze each problem carefully. Write your final answer in your notebook based on the given questions

solmaris [256]

Solving the given problems using the appropriate arithmetic operation such as multiplication, divison and addition, the answers are :

<em>4</em><em> </em><em>people</em><em> </em>
<em>1000</em><em> </em><em>ml</em><em> </em>
<em>$</em><em>1960</em>

Total size of pizza = $2 \frac{2}{3} = \frac{8}{3}$

Number of pizzas gotten by each person = $\frac{2}{3$

<u>Number of people sharing pizza</u> :

$\frac{8}{3} \div \frac{2}{3} = \frac{8}{3} \times \frac{3}{2} = 4 \: people$

2.)

<em>Volume bottle = 600 ml</em>

Fraction of water = $\frac{3}{5}$

Volume of full bottle = $\frac{3}{5} \times n = 600 = \frac{3n}{5} = 600$

Volume of full bottle = $\frac{3n}{3000}$

Volume of full bottle = $n = \frac{3000}{3} = 1000 ml$

3.)

Amount left = Php. 980
Fraction spent = $\frac{4}{8}$

<em>Let the monthly salary = m</em>

Fraction left = $1 - \frac{4}{8} = \frac{4}{8} = \frac{1}{2}$

Hence,

$\frac{1}{2} \times m = 980$

$\frac{m}{2} = 980$

$m = 980 \times 2 = 1960$

Therefore, Joel's monthly salary is $1960
