Find the area of each figure. If necessary, use 3.14 for π and round to the nearest hundredth. (Example 1)

Answers

Answer:

113 cm²

Step-by-step explanation:

You want the area of the given composite shape.

Composition

The shape is already divided for you into a lower part that is a trapezoid and an upper part that is a parallelogram.

Trapezoid

The area of the trapezoid is given by ...

A = 1/2(b1 +b2)h

A = 1/2(14 +7)(6) = 63 . . . . square centimeters

Parallelogram

The area of the parallelogram is given by ...

A = bh

A = (10)(5) = 50 . . . . square centimeters

Figure area

The area of the figure is the sum of the areas of its parts:

figure area = trapezoid area + parallelogram area

figure area = 63 cm² +50 cm² = 113 cm²

The area of the figure is 113 square centimeters.

Jaden’s teacher had 4 boxes of pens that each contained y pens. She took 6 pens out of one of the boxes and told her 17 students to divide the remaining pens equally among themselves. Which expression shows the number of pens each student got?

Answers

Answer:

[tex]\frac{4y - 6}{17}[/tex]

Step-by-step explanation:

There are 4 boxes containing y number of pens. This means that in 4 boxes there are y pens so we multiply 4 and y. The teacher then takes 6 pens out so you minus the amount of pens from the 4y leaving 4y - 6.The teacher then asks the students to share the pens out between 17 of them equally. To do this you must divide by 17 to get an equal number of pens for each student. This means the correct expression is [tex]\frac{4y - 6}{17}[/tex]

Let's do each equation to find which has the value of 128. A is 2 to the power of 7 means you multiply 2, 7 times, so 2 times 2 is 4, 4 x 2 = 8, 8 x 2, 16, 16 x 2 = 32, 32 x 2 = 48, and 48 x 2 is 96, so answer A is incorrect. B is 2 times 4 to the power of 3 so 4 x 4 is 16 and 16 x 4 is 64, since I have to multiply that number by 2, I get a total of 128. Well that's the answer so the others are incorrect ( A, C, and D).

The scatter plot shows the relationship between the amount of time, in hours, students in a Spanish class slept the night before an exam and their score on the exam.
Which of the following describes the pattern of association for the scatter plot?

There is a positive linear association.
There is a positive nonlinear association.
There is a negative linear association.
There is a negative nonlinear association.

Answers

Answer: Positive Nonlinear Association

Step-by-step explanation:

Take a look at the graph. From what we can see, it is going up. Hence, it's positive (meaning C and D are not the answer).

The way to tell between linear and nonlinear is the line. If you can perfectly fit all the points on a straight line, then it is linear. Clearly, you can't fit all the points on a singular straight line here, so it is nonlinear.
