The question is
ELEN [110]

Answer:

C

Step-by-step explanation:

4.5 is 45 ÷ 10 and 81.1 is 811 ÷ 10 so that means that 4.5 × 81.1 = 45 ÷ 10 × 811 ÷ 10 = (45 × 81) ÷ 100. We know that 45 × 81 = 36,495 so we just have to divide that by 100 to get 364.95.

A silo is to be built by attaching a hemisphere roof onto a circular cylinder. The hemisphere part of the silo is constructed by
crimeas [40]

The radius and height, in two decimal places are mathematically given as

r=10.60

<h3>What is the radius and height, in two decimal places?</h3>

Generally, the equation for the volume is mathematically given as

V=\pi r^{2} h+\frac{2}{3} \pi r^{3}

Therefore

5000 &=\pi 0^{2} h+\frac{2}{3} \pi r^{3}

V(r, h) &=\pi r^{2} h+\frac{2}{3} \pi r^{3}-5000 \\\nabla V &=\left\langle 2 \pi r h+2 \pi r^{2}, \pi r^{2}\right\rangle \\

\cos t &=100\left(2 \pi r^{2}\right)+75(2 \pi r h) \\\\\cos t &=200 \pi r^{2}+150 \pi r h \\\\\nabla C(r, h) &=\langle 400 \pi r+150 \pi h, 150 \pi r\rangle

Using Lagrange method

$\langle 400 \pi \gamma+150 \pi \gamma h, 150 \pi \gamma\rangle=\lambda\left\langle 2 \pi \gamma h+2 \pi \gamma^{2}, \pi r^{2}\right\rangle$

$400 \pi r+150 \pi r=\left(2 \pi r h+2 \pi r^{2}\right) \lambda$

$400 \pi \gamma+150 \pi h=300 \pi h+300 \pi r \\\\

$400 \pi r-300 \pi r=150 \pi h$

$160 \pi r=150 \pi h \quad \\\\\\

with

h=\frac{2}{3} r $

$\pi r^{2} h+\frac{2}{3} \pi r^{3}=5000$

\pi r}\left(\frac{2}{3} r \right)+\frac{2}{3} \pi^{3}=5000$

$\frac{4 \pi \gamma^{3}}{3}=5000 \quad

r^{3}=\left(\frac{5000 \times 3}{4 \pi}\right)$

r=10.60

In conclusion, the radius and height, in two decimal places is

r=10.60

a ice cream factory makes 290 quarts of ice cream in 5 hours . how many quarts can be made in 48 hours
kodGreya [7K]

Answer:

2,784 quarts

Step-by-step explanation:

we first must find out how many quarts it can make per hour.

we do this by dividing 290 by 5 which gives you 58.

then you just multiply 58 by 48 which gives you 2,784.

MAKE SURE TO REMEMBER UNITS! Teachers like to take away points for that.

Jenine wants to purchase a home for $110,000. Her bank is offering her 6% interest rate for a 30 year mortgage. Jenine has saved
ch4aika [34]

L is the loan amount. We know that Jenine has saved a 15% downpayment, meaning she will pay 15% of house price at the time of borrowing.

After 15% is subtracted from the house price, the remaining amount is 85%, meaning Jenine will now only need to borrow 85% of the house price to purchase the house.

85% of the house price is

\frac{85}{100}\times110,000=93,500.

Hence, the loan amount is L = $93, 000.

Jenine paid 15% of the house price, right?

Now she has only 100% - 15% = 85% of the price left to pay.

Do you agree?
