Answer:

read the question and you will find the like the question and just find it out The weather report says the temperature is 20°c and will drop 5°c per hour for the next 6 hours.

Temperature drops by 5°c per hour

So we find the temperature after 6 hours

In 1 hour temperature drops= 5°c

So in 6 hours = 6* 5 = 30°c

In 6 hours , temperature drops by 30°c

the actual temperature is 20°c. after 6 hours the temperature becomes

20°c - 30°c= -10°c

So, after 6 hours the temperature will be -10°c

Daryl plans to be gone for at least 6 hours. so its 6 hours or more than 6 hours

In 6 hours or more than 6 hours , the temperature will drop less than -10°c

Can you help me with this plzzzzzzz

Answer:

E: x = 13

F: x = 1.5 or 3/2

Step-by-step explanation:

This is for E:

x + 2/3 = 5

All you do is first multiply 5 * 3

and you will get 15

x + 2 = 15

Then you subtract from 15

15 - 2 = 13

So x = 13

This is for F:

10(x - 1) = 5

So all you do is distribute the 100 with x -1

10 * x = 100x

10 * -1 = 100

10x - 10 = 5

Then you add 10 to 15 because the number is -10

5 + 10 = 15

10x = 15

Now you divide by 10 on both sides

10x/10 = 15/10

10x/10 = x

15/10 = 3/2

So the answer for F is 3/2 or 1.5

Find the area of this rhombus

Vikentia [17]

<h2>Hello!</h2>

The answer is:

The area of the rhombus is equal to 64 squared inches.

$area=64in^{2}$

<h2>Why?</h2>

Since we already know half of the length of the diagonals of the rhombus, we can calculate the area of the rhombus using the following formula:

$area=\frac{diagonal_{1}*diagonal_{2}}{2}$

From the image we can see that:

$diagonal_{1}=8in+8in=16in$

$diagonal_{2}=4in+4in=8in$

So, substituting, we have:

$area=\frac{16in*8in}{2}=\frac{128in^{2} }{2}=64in^{2}$

Hence, we have that the area of the rhombus is equal to 64 square inches.

Have a nice day!

LeAnn wants to giftwrap a present she got for her little brother. How many square inches of giftwrap will be needed to cover a b

Sloan [31]

For this case we must find the surface area of a rectangular prism.
We have then:
$A = 2 * (w * l) + 2 * (w * h) + 2 * (l * h)
$
Where,
w: width
l: long
h: height
Substituting values we have:
$A = 2 * (4 * 6) + 2 * (4 * 2) + 2 * (6 * 2)

A = 88 in ^ 2$
Answer:
There will be needed 88 in ^ 2 of giftwrap to cover the box

Complete the work to solve for y:<br><br> What is the value for y?

ollegr [7]

Answer:

The value of y = 11/2

Step-by-step explanation:

As the work is completed up to the point

$\frac{11}{5}=\frac{2}{5}y$

Now completing the remaining work

$\frac{11}{5}=\frac{2}{5}y$

Dividing both sides by 2/5

$\frac{11}{5}\div \frac{2}{5}=\frac{2}{5}y\div \frac{2}{5}$

$\frac{2}{5}\cdot \frac{5y}{2}=\frac{\frac{11}{5}}{\frac{2}{5}}$ ∵ $\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{a}{\frac{b}{c}}=\frac{a\cdot \:c}{b}$

$\frac{2y\cdot \:5}{5\cdot \:2}=\frac{\frac{11}{5}}{\frac{2}{5}}$ ∵ $\mathrm{Multiply\:fractions}:\quad \frac{a}{b}\cdot \frac{c}{d}=\frac{a\:\cdot \:c}{b\:\cdot \:d}$

$\frac{y\cdot \:5}{5}=\frac{\frac{11}{5}}{\frac{2}{5}}$ ∵ $\mathrm{Cancel\:the\:common\:factor:}\:2$

$y=\frac{\frac{11}{5}}{\frac{2}{5}}$ ∵ $\mathrm{Cancel\:the\:common\:factor:}\:5$

$y=\frac{11\cdot \:5}{5\cdot \:2}$ ∵ $\mathrm{Divide\:fractions}:\quad \frac{\frac{a}{b}}{\frac{c}{d}}=\frac{a\cdot \:d}{b\cdot \:c}$

$y=\frac{11}{2}$ ∵ $\mathrm{Cancel\:the\:common\:factor:}\:5$

Therefore, the value of y = 11/2
