"bananas cost 89 cents each at the fruit stand.. Isabel has $11.75. how many bananas can she buy?" i forgot how to do this stuff pls help​

Answers

Answer:

She can buy 13 bananas

Step-by-step explanation:

She has 11.75 and each banana costs .89

Start by dividing 11.75/.89 = 13.20

She will be able to buy 13 bananas total since she cannot buy a portion of a banana (0.2) so she will just have some leftover change.

She’s right it’s 13.20

What is the area of the parallelogram?

A parallelogram with base of 20 centimeters, height of 15 centimeters, and side length 21 centimeters.
82 centimeters squared
300 centimeters squared
315 centimeters squared
420 centimeters squared

Answers

Answer:

300 centimeters squared.

Step-by-step explanation:

Given that a parallelogram has a base of 20 centimeters, a height of 15 centimeters, and a side length 21 centimeters, to determine the value of its area, the following calculation must be performed:

Area = Base x Height

Area = 20 x 15

Area = 300

Thus, the area of the parallelogram is 300 square centimeters.

Solve for x. Leave your answer in simplest radical form

Answers

Answer:

x = sqrt(39)

Step-by-step explanation:

Let y = common side of the two triangles.

Upper right triangle:

6^2 + y^2 = 10^2

y^2 = 100 - 36

y^2 = 64

y = 8

Lower left triangle:

5^2 + x^2 = 8^2

x^2 = 64 - 25

x^2 = 39

x = sqrt(39)

3. If a+b=c, then what is the average value of a,b are c?

Answers

Answer:

The average value of a, b and c is [tex]\frac{2c}{3}[/tex]

Step-by-step explanation:

Average value:

Sum of all values by the number of values.

In this question:

3 values, a, b and c.

We have that:

[tex]A = \frac{a+b+c}{3}[/tex]

Since [tex]a+b = c[/tex]

[tex]A = \frac{a+b+c}{3} = \frac{c+c}{3} = \frac{2c}{3}[/tex]

The average value of a, b and c is [tex]\frac{2c}{3}[/tex]

What is the x-intercept of the graph of Y= 4x-36

Answers

The x-intercept is -36.

y = 4x - 36
The y is your y-intercept.
The 4x is your slope. (4/1)
The -36 is your x-intercept.

The x - intercept of the line is at Point X(9, 0).

We have the following equation of a straight line -

y = 4x - 36

We have to find the x - intercept of the of this line.

What is the general equation of a straight line ?

The general equation of a straight line is as follows -

y = mx + c

where -

m - slope of line

c - intercept of line on y - axis.

According to the question, we have -

y = 4x - 36

Now, comparing this line with the general equation of line -  y = mx + c, we get -

m = 4

c = - 36

for the x - intercept of the line, substitute y = 0. We get -

0 = 4x -36

4x = 36

x = 9

Hence, the x - intercept of the line is at Point X(9, 0).

Refer to the graph attached for more clarity.

Quirky gives inventors a design team that helps them bring their thoughts to life. The staff of Quirky (75 people and growing) listens to proposals for new projects and votes on which products the company will make. One famous example of a Quirky product was invented by a salesman who lived in Baltimore. He noticed that people who lived in apartment buildings kept large air conditioners hanging out of their windows. Those air conditioners would run all day. He invented a slim air conditioner that can be turned on and off using a phone app. His air conditioners use less energy than old-fashioned air conditioners. Without the team at Quirky, he never would have been able to make his idea a reality. What can we infer about the salesman from Baltimore? He used to work as an air conditioning repairman. He was nervous to present his product at Quirky. He doesn't like seeing air conditioners in windows. He believes that working with others is a smart business move.
