4 0

Answer:

A number divided by 12 is equal to 4 multiplied by the sum of that number and 3

Step-by-step explanation:

If we suppose that "v" represents "a number," then the expression on the left is "a number divided by 12." That eliminates the first and last choices.

The expression on the right is the product of 4 and a sum, eliminating the third choice and confirming that the second choice is the correct one.

Why do banks give out there credit cards easily and offer to reward tgem

Masteriza [31]

Answer:

If the cardholder has a participating cash back rewards program, the credit card issuer simply shares some of the merchant fees with the consumer. The goal is to incentivize people to use their credit cards when making payments rather than cash or debit cards, which earns them no rewards.

PLEASE PLEASE HELP

Answer:68.3 degrees

Step-by-step explanation:

The diagram of the triangle ABC is shown in the attached photo. We would determine the length of side AB. It is equal to a. We would apply the cosine rule which is expressed as follows

c^2 = a^2 + b^2 - 2abCos C

Looking at the triangle,

b = 75 miles

a = 80 miles.

Angle ACB = 180 - 42 = 138 degrees. Therefore

c^2 = 80^2 + 75^2 - 2 × 80 × 75Cos 138

c^2 = 6400 + 5625 - 12000Cos 138

c^2 = 6400 + 5625 - 12000 × -0.7431

c^2 = 12025 + 8917.2

c = √20942.2 = 144.7

To determine A, we will apply sine rule

a/SinA = b/SinB = c/SinC. Therefore,

80/SinA = 144.7/Sin 138

80Sin 138 = 144.7 SinA

SinA = 53.528/144.7 = 0.3699

A = 21.7 degrees

Therefore, theta = 90 - 21.7

= 68.3 degees

Answer:

i got them right

Step-by-step explanation:

A is translated and congruent

B is dilated and similar

C is reflected and congruent

depending on how your quiz is when is say and then a word like "congruent" that word is the one you type in and the other word translated,dilated and reflected is from the drop down bar. any questions on how this is set up

a satellite's escape velocity is 6.5 mi/sec, the radius of the earth is 3960 mi, and the earth's gravitational constant is 32.2

Artyom0805 [142]

Answer:

$23.89x10^{6}$ ft

Step-by-step explanation:

$\frac{V^{2} }{R^{2} } = \frac{2g}{R+h} \\$ This is the formula to find satellite's escape velocity V , where R is earth's radius, h is the satellite's height from the earth surface and g is the earth's gravitational constant.
