Answer:

y=8

Step-by-step explanation:

if y = -x +7

then

y= 1 + 7 cause we know x = -1 so negative x is 1

so 1+7=8

so y = 8

hope this helped :)

Aliens have injected Ana with mathematical nanobots. These nanobots force Ana to think about math more and more. Initially, ther

natulia [17]

Answer:

<em>Math will take over Ana's brain at 4.4 hours</em>

Step-by-step explanation:

<u>Exponential Grow </u>

The population of the nanobots follows the equation

$p(t) = 5\cdot 2^t$

We must find the value of t such that the population of nanobots is 106 or more, that is

$5\cdot 2^t\geq 106$

We'll solve the equation

$5\cdot2^t= 106$

Dividing by 5

$2^t= 106/5=21.2$

Taking logarithms

$log(2^t)= log(21.2)$

By logarithms property

$t\cdot log(2)= log(21.2)$

Solving for t

$\displaystyle t=\frac{log21.2} {log2}$

$t=4.4 \ hours$

Math will take over Ana's brain at 4.4 hours

The volume of a cylinder is 156 x cm3. What is the volume of a cone with the same base and height as the cylinder?

Flura [38]

Answer: SECOND OPTION (52 cm³)

Step-by-step explanation:

The formula for calculate the volume of a cone is:

$V{co}=\frac{1}{3}r^{2}h\pi$

Where r is the radius and h is the height.

The formula for calculate the volume of a cylinder is:

$V{cy}=r^{2}h\pi$

Where r is the radius and h is the height.

As you can see, the difference between the the formulas is that r²hπ of the cone is divided by 3. Therefore, if you know the volume of the cylinder and you know that the cone has the same base and height as the cylinder, you have to divide the volume of the cylinder by 3 to obtain the volume of the cone.

Therefore, the result is:

$V{co}=\frac{156cm^3}{3}=52cm^3$

Soleil and Malvin each work a job. Soleil starts with $700 and makes $100 per day. Malvin starts out with $200 and makes $120 pe

Goshia [24]

Answer:

Soleil and Malvin would have $ 5,000 all together after 13 days.

Step-by-step explanation:

Since Soleil and Malvin each work a job, and Soleil starts with $ 700 and makes $ 100 per day while Malvin starts out with $ 200 and makes $ 120 per day, to determine after how many days will they have at least $ 5000 all together it must be done the following calculation:

5,000 - 700 - 200 = 4,100

200X + 120X = 4,100

320X = 4,100

X = 4,100 / 320

X = 12.8

So Soleil and Malvin would have $ 5,000 all together after 13 days.
