Answer:

+15

Step-by-step explanation:

An increase is generally regarded as being positive. If units are dollars, an increase of $15 can be represented by the integer +15.

Additional comment

If units are dimes, then the number would be +150. So, you see, the units are important to know.

It also depends on what is increasing and what is being represented by the integer. If it is an increase in debt, then the change in net worth might be -15.

Kamila buys a notebook for $1.59 and pens for $0.29 each. She spends $5.07.

emmasim [6.3K]

Answer:

12 pens

Step-by-step explanation:

Let the variable that can be used to determine the number of pens that Kamila bought be represented by n.

Price of a notebook = $1.59

Price a pen = $0.29

Total amount spent = $5.07

But,

1.59 + 0.29 n = 5.07

So that,

0.29 n = 5.07 - 1.59

0.29 n = 3.48

n = $\frac{3.48}{0.29}$

= 12

Therefore, Kamila bought 12 pens.

find the length of each isosceles right triangle when the hypotenuse of the given measure given 5 to the square root of 6

iragen [17]

In isosceles right triangle, legs are equal. Let each leg is of x units . And the given hypotenuse is 5 square 6. We use pythagorean identity here, which is

$a^2 + b^2 = c^2$

Where a=b=x and c= 5 square root 6

$x^2 +x^2 =(5 \sqrt6)^2$

$2x^2 = 150$

$x^2 =75$

$x= 5 \sqrt 3$

And that's the length of both the legs . ANd that's the required answer .

Find the volume of a sphere with surface area equal to 100π ft^2

Anni [7]

Answer:

$V=\frac{500}{3}\ \pi(ft^{3})$

Step-by-step explanation:

Hello.

to find the volume of a sphere we must know its radius,

we don't know the radius but we have the area

$A=4\pi r^{2} \\ \\isolating\ r\\\\A=4\pi r^{2}\\r=\sqrt{\frac{A}{4\pi } } \\r=\sqrt{\frac{100\ ft^{2} }{4\pi}} \\\\ r= \sqrt{25\ ft^{2} }\\ r=5\ ft\\$

Now, replacing this value in the volume equation

$V=\frac{4\pi r^{3} }{3} \\V=\frac{4\pi\ (5\ ft)^{3} }{3}\\ V=\frac{4\pi\ (125 ft^{3}) }{3}\\V=\frac{500}{3}\ \pi (ft^{3})\\\\\\$

have a great day
