A cylindrical grain bin has a radius of 5 feet and a height of 29 feet. What is the surface area of the bin? A. 1,067.6 ft2

B. 157 ft2

C. 910.6 ft2

D. 612.3 ft2

Hurry! pppplllleeeeeaaaasssseeeee!

Hello!

To solve this you use the equation to find the surface area of a cylinder

SA is surface area

r is radius

h is height

Put in the values you know and 3.14 for pi

SA = 2 * 3.14 * 5 * 29 + 2 * 3.14 * 5^2

SA = 1067.6

The answer is A)1,067.6ft squared

Hope this helps!

Find the value of the variable which satisfies the equation by trying the values given in bracket: m/2= 5 (2 , 5 , 10 , 15)

M/2=5

When 2 comes to the right hand side it multiplies with 5

m= 2x5

Therefore,m=10

Hope this helps

At a hockey game a vendor sold a combined total of 110 sodas and hot dogs. The number of hot dogs sold was 42 less than the number of sodas sold. Find the number of sodas sold and the number of hot dogs

76 sodas and 34 hot dogs were sold by the vendor.

Step-by-step explanation:

Given,

Total sodas and hot dogs sold = 110

Let,

x be the number of sodas sold

y be the number of hot dogs sold

According to given statement;

x+y=110 Eqn 1

y = x-42 Eqn 2

Putting value of y from Eqn 2 in Eqn 1

Dividing both sides by 2

Putting x=76 in Eqn 1

76 sodas and 34 hot dogs were sold by the vendor.

How can you use multiplication to check your answer ?

Answer:

You can use multiplication to check your division answer this way.

Do the division problem.

Multiply the quotient times the divisor.

If there is a remainder, add it to the multiplication product.

Compare this answer to the dividend. They should be the same number (630 = 630).

Math question 8v2+8v-48 ?

0 = 8v^2+8v-48

=8(v^2+v-6)

=8(v-2)(v+3)

so v= 2 or v=-3

=8(v^2+v-6)

=8(v-2)(v+3)

so v= 2 or v=-3

Im guessing that 8v2 means 8v² so that's how I will solve it

first, factor

(8v-16)(1v+3)

--------------------------

if finding v values, set each =0

8v-16=0

8v=16

v=2

------------

v+3=0

v=-3

first, factor

(8v-16)(1v+3)

--------------------------

if finding v values, set each =0

8v-16=0

8v=16

v=2

------------

v+3=0

v=-3

Karl visited his doctor because he found he had difficulty sitting upright and controlling his hands and movements. Which neurological disorder do you think Karl may have?

A amyotrophic lateral sclerosis

B. multiple sclerosis

C. Alzheimer disease

D. Parkinson disease

Answer:

A. amyotrophic lateral sclerosis

Step-by-step explanation:

This condition is also known as Lou Gehrig’s disease, after a professional baseball player who had the disease. ALS is a rapidly progressive, fatal disease that attacks the nerve cells responsible for controlling voluntary muscles. Because the muscles no longer receive nerve impulses, they atrophy (waste away). People with ALS lose the ability to move their arms and legs and hold their body upright. Eventually, when the diaphragm muscles fail to function properly, individuals lose the ability to breathe without support. Most people with ALS die from respiratory failure three to five years after the onset of the disease.

Answer:

D. Parkinson disease

Step-by-step explanation:

Karl is having difficulty sitting upright and controlling his hands and movements. Among the given options for diseases corresponding to this symptom:

amyotrophic lateral sclerosis : causes weakness of muscles and loss of control of muscles.

multiple sclerosis : causes breakdown of signal transmission between brain and rest of the body.

Alzheimer disease : causes loss of memory and cognition

Parkinsons disease : causes difficulty in balancing the body and limb movement.

So among the given options Parkinsons disease is the most relevant neurological disorder corresponding the symptoms exhibited by Karl.
