Insert parentheses to make each statement true.
oksano4ka [1.4K]

Answer:

a. (2+3)×4²+1=81

b. (2+3)×(4²+1)=85

c.  2+(3×4²)+1=51

d. 2+3×(4²+1)=53

Step-by-step explanation:

a. Parentheses about the 2 + 3  - then use PEMDAS to give 5 * 16.

b Inserting 2 parentheses makes it 5 * 17 = 85.

c.Inserting the parentheses simplifies it to 2 + 48 + 1 = 51.

d. Inserting the parentheses  makes it 2 + 3*17 = 53

in the figure below trianglePQM and triangleQRP are right triangles. the measure of lineQM is 6 and the measure of lineQP is 8.
Kipish [7]

Answer:

Option 4 is correct. The length of PR is 6.4 units.

Step-by-step explanation:

From the given figure it is noticed that the triangle PQR and triangle MQR.

Let the length of PR be x.

Pythagoras formula

hypotenuse^2=base^2+perpendicular^2

Use pythagoras formula for triangle PQM.

PM^2=QM^2+PQ^2

PM^2=(6)^2+(8)^2

PM^2=36+64

PM^2=100

PM=10

The value of PM is 10. The length of PR is x, so the length of MR is (10-x).

Use pythagoras formula for triangle PQR.

PQ^2=QR^2+PR^2

(8)^2=QR^2+x^2

64-x^2=QR^2                   .....(1)

Use pythagoras formula for triangle MQR.

MQ^2=QR^2+MR^2

(6)^2=QR^2+(10-x)^2

36=QR^2+x^2-20x+100

36-x^2+20x-100=QR^2        .... (2)

From equation (1) and (2) we get

36-x^2+20x-100=64-x^2

20x-64=64

20x=128

x=6.4

Therefore length of PR is 6.4 units and option 4 is correct.

31 one is in the middle, also you have to sort it for least to greatest.

Mean- Add all the number then divide by the numbers there are.

Mode-It has occored the most

Range- sort least to greatest, then subtract the highest number to the lowest
