A restaurant sells 10 tacos for $8.49, or 6 of the same kind of taco for $5.40. Which is the better deal?

Answers

Answer:

10 tacos

Step-by-step explanation:

10 tacos is the better deal because

it is 0.85 cents. 0.85 x 10 = $8.50 per taco for 10 tacos while it would cost $0.90 per taco for 6 tacos

0.90 x 6 = 5.40.

Hope this helps.

Graph the following pair of quadratic functions and describe any similarities/differences observed in the graphs.
f(x)=8x^2+2

The difference between the two graphs is that the first one is increasing which means that it’s going positive infinity. While the second graph is decreasing which means that the errors are going negative infinity.

x = 16

4x = 64

Step-by-step explanation:

The sum of the exterior angles of any polygon is 360°

Add the given angles and solve for x

93 + 46+ 3x + 62 + 4x +47 = 360

7x + 248 = 360

7x = 360 –248

x = 16

Find the lateral surface area of the cylinder. Round your answer to the nearest tenth.

Radius - 7
height- 2

Answers

Answer: 87.9

Step-by-step explanation:

Since the formula is 2 x pi x radius x height, we plug the equation in.

If you use “3.14” for pi, it’s 2 x 3.14 x 7 x 2 = 87.9 (rounded to the nearest tenth)

2 x pi x 7 x 2 = 87.96 (88 rounded to the tenth)

ILL MARK YOU BRAINLIEST To join a health club, a person must pay a $75 one-time fee plus a charge of $30 per month. This situation can be presented by an equation of the form y=mx+b, where x = the fire in months and ythe
total cost in dollars. What is the value of b in this equation?

Answers

Answer: b=75

Step-by-step explanation: Given that the health club charges $30 per month, we know that this is the "m" varible. We know this because the total value changes as the value of x changes. The value of b would therefore be $75 dollars because it is a constant and a one time fee. The person joining the health club pays an amount of money per month, as well as an initial charge of $75.

use the figure below and determine the angle measures. what is the measure of angle G?

Answers

Answer:

45

Step-by-step explanation:

First we want to understand the Base Angles Theorem

The Base Angles Theorem tells us that the base angles or the two bottom angles of an isosceles triangle are congruent.

Using this theorem, we can say that angle A and angle G are congruent meaning m∠A = m∠G. We can then write both of them as x.

We can create the equation ∠N + ∠A + ∠G = 180 degrees.

Knowing ∠N and knowing ∠A + ∠G = 2x, we can rewrite the equation into

90 + 2x = 180

We can then solve for x,

90 + 2x - 90 = 180 - 90

2x = 90

2x / 2 = 90 / 2

x = 45 degrees

(2x+4)(x-2)

Answer:

2x squared - 8

Step-by-step explanation:

For this kind of equation, we use the distributive property

So in the image below I used a box method (that's how I learned it in school)

So since -4x and 4x cancel each other out, or amount to 0, we don't put anything for those. So the equation left is 2x squared - 8
