Answer:

2 cm

Step-by-step explanation:

h = 14 cm

Curved surface area of a right circular cylinder = 88 cm²

2πrh = 88

2 * \frac{22}{7}*r*14=88\\\\r = \frac{88*7}{2*22*14}\\\\ r =1 \\\\r = 1 cm

Diameter = 2 * r = 2 * 1 = 2  cm

Marcelina uses a blend of white corn and yellow corn to make tortilla chips at her restaurant. She needs to
UNO [17]

Answer:

Option C. Marcelina spends less that the intended amount of money and buy the correct amount of corn

Step-by-step explanation:

<u><em>The complete picture of the question in the attached figure</em></u>

Let

x---->  is the amount of white corn she buys

y ---> is the amount of yellow corn she buys

we know that

She needs to buy 50 kg of corn in total

so

x+y=50 ----> equation A

She wants to spend $12 dollars total

so

0.30x+0.15y=12 ----> equation B

The solution of the system of equations is the intersection point both graphs

The solution is the point (30,20)

That means

Marcelina needs to buy 30 kg of white corn and 20 kg of yellow corn

we have the ordered pair D(15.35)

That means

15 kg of white corn and 35 kg of yellow corn

therefore

Total kg of corn bought is

15+35=50\ kg\\50\ kg= 50\ kg

Total spend is

0.30(15)+0.15(35)=\$9.75\\\$9.75

therefore

Marcelina spends less that the intended amount of money and buy the correct amount of corn

When solving a compound inequality. Micah wrote the solution as x&gt; or equal to 50 OR x&gt;or equal to 75. What is a simpler w
REY [17]

Answer:

The best way of writing this answer in an inequality pattern is 50 ≤ x ≥ 70

Step-by-step explanation:

The variable "x" is said to be greater than or equal to 50, that means that x could be 50, 51, 52, 53, 54......to infinity, all these values are true for x.

The second solution said x is greater or equal to 70. This also means that x could be 70, 71, 72, 73, ......... to infinity.

The inference that can be drawn from here is that x actually started from 50, so anything lesser than 50 is lesser than x, so 50 ≤ x. We can join the two answers together to get a range in a form like: 50 ≤ x ≥ 70
