Answer:

Each text costs 5 cents ($0.05)

Step-by-step explanations:

To find the cost of one text, divide the $6.00 by 120.

You will come up with 0.05, meaning the correct answer is 5 cents

The cost of each text message is 0.05 dollar.

What is Unitary Method?

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Given:

Cost of 120 text messages = $6

So, price to pay for 1 text message is

=6/120

=1/20

= 0.05 dollar

Hence, the cost of each text message is 0.05 dollar.

Answer:

Step-by-step explanation:

The sum of angles in a triangle is 180°. In an isosceles triangle, the base angles are congruent.

For this, it is easiest to find the base angles first. If we let b represent the measure of one of them, the sum of angles is ...

  2b +42 = 180

  b +21 = 90 . . . . . . divide by 2

  b = 69 . . . . . . . subtract 21

The measure of the base angles is 69°.

__

Then we can find the value of x from its relation to the base angle measure:

  (2x +3)° = 69°

  2x = 66 . . . . . . . . . divide by °, subtract 3

  x = 33 . . . . . . . . divide by 2

The value of x is 33.

Answer:

x = 33

each base angle measures 69°

1 6/8

Step-by-step explanation:

eight goes into fourteen 1 time with a remainder of 6

Step-by-step explanation:

I am not sure what you mean.

do you mean to see, if this can be a right-angled triangle, and if so, what is the Hypotenuse, and what are the legs ?

I assume this to be the case.

so, we must be able to build a Pythagoras equality

c² = a² + b²

28² = 784

53² = 2809

45² = 2025

indeed, we see right away, 45² + 28² = 53²

confirmed, it is a right-angled triangle, with 53 being the Hypotenuse.

In an hour, the first pipe can fill up 1/8 of the pool
In an hour, the second pipe can fill up 1/12 of the pool
In an hour, the third pipe can fill up 1/24 of the pool.

So, in an hour, the 3 pipes can fill up 1/8 +1/12 + 1/24 = 6/48 + 4/48 + 2/48 = 11/48 of the pool.

It will take the 3 pipes 1 : 11/48 = 48/11 hours to fill the pool.

The quadratic function that has x-intercepts at x = 3, and x = -5 that

passes through the point (1, -12) is f(x) = x² + 2·x - 15.

The intercepts of the graph of the quadratic function are x = 3 and x = -5

The point through which graph passes is (1, -12)

Required:

The equation of the quadratic function.

Solution:

Given that the intercepts are x = 3, and x = -5, we have;

x = 3, and x = -5 are the zeros of the quadratic function, which gives;

Factors of the quadratic function are; (x - 3) and (x + 5)

From which we have;

(x - 3) × (x + 5) = x² + 2·x - 15 is a factor of the quadratic function

When x = 1, we have;

1² + 2 × 1 - 15 = -12

Therefore, the point (1, -12) is a point on the quadratic function x² + 2·x -

15 that has intercepts at x = 3, and x = -5

The equation of the quadratic function is therefore;

Answer:

Step-by-step explanation:

If Kareem sold 28 pounds of tomatoes, then we first need to figure out, how much money she earned from that. That will be done by multiplying.

Since 1pound=$3

28x3=?

20x3=60

8x3=27

60+27=87

So, Kareem earned 87 dollars from selling all the tomatoes.

Now, we have to find out, how many dollars did the asparagus make for her.

That will be done by subtracting 180 by 87

180-87=?

180-80=100

100-7=93

So, the money that Kareem earned from selling all the Asparagus was $93.

Now, we have to find the amount of pounds of Asparagus did Kareem sell.

That will be done by dividing 4 by 93. (You can already say that the answer will be in decimals, or with a remainder)

93/4=

80/4=20

13/4=3.25 (since, 4x3=12, 4 parts of 100=25%, that's why that's the answer)

20+3.25=23.25

ANSWERS INFO:

Kareem earned: $180

Kareem sold pounds of tomatoes : 28

Kareem sold pounds of Asparagus : 23.25

Answer:

Statements:

m<b = 180 - m<a

m<c = 180 - m<d

m<b = m<c

180 - m<a = 180 - m<d

Reasons:

The measure of m<b is the angle of a straight line subtracted with m<a. The measure of m<c is the angle of a straight line subtracted with m<d. If m<a and m<d are equal, m<b and m<c are equal.

Step-by-step explanation:

We know, m<a = m<d

So, we need to prove m< b = m<c

Let's start by defining what b and c is

m<b + m<a = 180 This is because a straight line is 180 degrees

m<b = 180 - m<a

m<c + m<d = 180

m<c = 180 - m<d

With this, we can substitute in proof

m<b = m< c

180 - m<a = 180 - m<d

180 - m<a = 180 - m<a
