Answer:

20n

Step-by-step explanation:

One pretzel has 20 calories. Write an algebraic expression for the total number of calories in n pretzels.

1 pretzel = 20 calories

n pretzel = x

Cross Multiply

x × 1 pretzel = n pretzel × 20 calories

x = n pretzel × 20 calories/1 pretzel

x = 20 n

Therefore, an algebraic expression for the total number of calories in n pretzels = 20n

The sum of twice a number and three is greater than forty-nine

mestny [16]

We divide both sides by 2 to isolate x...
x > 23
There you go. Any number greater than 23 is a correct answer to your problem. Let's verify by substituting x for 24.
2(24) + 3 > 49
48 + 3 > 49
51 > 49

Riders on a Ferris wheel travel in a circle in a vertical plane. A particular wheel has radius 20 feet and revolves at the const

Zarrin [17]

It will take a rider 10 seconds to travel from the bottom of the wheel to a point 10 vertical feet above the bottom.

The radius of the wheel is 20 feet it revolves at the constant rate of one revolution per minute

using cos function,

cos ∅ = $\frac{\frac{R}{2} }{R}$

= $\frac{10}{20}$

= $\frac{1}{2}$

∅ $=60^{0}$

we know that, 1 minute = 60 seconds = $360^{0}$

1 second= $6^{0}$

∴Time = $\frac{60}{6}$ =10 seconds

Hence, it will take a rider 10 seconds to travel from the bottom of the wheel to a point 10 vertical feet above the bottom.

quester [9]

Answer: 42 bowls were sold in the month of December.

Step-by-step explanation:

Here, The company models its profit, P, using the formula $P=u^2-4 u-8$ , where u is the number of bowling balls the company sells.

Since, Dobbs Bowling Company made a profit of $1,588 during the month of December.

Therefore, $1588=u^2-4 u-8$

⇒ $u^2-4 u-8=1588$

⇒ $u^2-4 u-1596=0$

⇒ $u^2-42u+38u-1596=0$

⇒ $u(u-42)+38(u-42)=0$

⇒ $(u+38)(u-42)=0$

⇒ u = 42 and -38

Since, The number of balls can not be negative.

Therefore, total number of the bowling balls in December that are sold = 42
