Answer:

I really don't get what you're asking but in finding the new area 20 feet and 10 feet I found the area and the perimeter 14 cm2. I have found both perimeter and area so if you wanted an answer I guess it is in one of my answers.

Will mark brainliest please help Debbie notices that the amount owed on her monthly heating bill varies inversely with the avera

Alekssandra [29.7K]

Answer:

The bill is $1837.5

Step-by-step explanation:

Given

$B = Bills$

$T = Temperature$

$B\ \alpha\ \frac{1}{T}$ --- The variation

T = 35; when B = 210

Required

Find B when T = 40

$B\ \alpha\ \frac{1}{T}$

Express as an equation

$B = \frac{k}{T}$

Make k the subject

$k = BT$

$k = 35 * 210$

$k = 7350$

When T = 40, we have:

$k = BT$

$7350 = B * 40$

Make B the subject

$B = \frac{7350}{4}$

$B = 1837.5$

Dario bakes a lasagna containing $\frac 23$ pound of parmesan cheese, $1\frac 14$ pounds of ricotta cheese, and $1\frac 13$ poun

svp [43]

Answer: There are 13 slices when Dario cuts .

Explanation :

Since we have given that

Quantity of parmesan cheese is given by

$\frac{2}{3}$

Quantity of ricotta cheese is given by

$1\frac{1}{4}$

Quantity of mozzarella cheese is given by

$1\frac{1}{3}$

Now, total quantity of cheese Dario have

$\frac{2}{3}+\frac{5}{4}+\frac{4}{3}=2+\frac{5}{4}=\frac{8+5}{4}=\frac{13}{4}$

Now,

According to question, Dario cuts the lasagna into several equal slices and each containing exactly

$\frac{1}{4}\ pounds\ of\ cheese$

So,

Number of slices is given by

$\frac{\frac{13}{4}}{\frac{1}{4}}=13$

Hence, there are 13 slices when Dario cuts .
