Answer:

16 sq meters

Explanation

Surface area is the area of the figures combined. Find area of base and triangles then add.

2×2=4

2×3÷½=3

since there are 4 triangles you do 3×4

12+4= 16

Jorge needs to reflect a figure across the line y= -4 Which statements are correct regarding steps he could take to complete the
Serjik [45]

Answer:

see below. × signifies a wrong choice; → signifies a correct one

Step-by-step explanation:

× Jorge should graph in the vertical line with values of –4 for the line of reflection. (The line of reflection is horizontal.)

→ Jorge could count how far each pre-image point is from the line of reflection along the perpendicular from the point to the line of reflection.

× Jorge could count how far each vertex of the figure is from the y-axis and count the same distance on the other side. (He could do this pointless exercise, but it has no relation to the problem. The y-axis (x=0) is not the line of reflection.)

→ Jorge will not move any point that lies on the line of reflection. (All points on the line of reflection are reflected to themselves.)

→ Jorge could check his work by seeing if each segment joining a pre-image point with its image has the midpoint on the line of reflection. (This is what is meant by "line of reflection.")

× Jorge could check his work by making sure that the image has the same orientation as the original. (A reflected image as an orientation opposite that of the original, a fact you see every time you look in a mirror.)

Why are the soulution to the proportions 50/x = 10/20 and 10/50= 20/x
Marianna [84]

Answer:

Step-by-step explanation:

You should croos multiply to get 10x = 50 (20) which is 10x = 1000 then divide each side by 10. What do you get for x?

what is the quotient (65y3 15y2 − 25y) ÷ 5y? a. 13y2 3y − 5 b. 13y3 3y2 − 5y c. 13y2 − 3y 5 d.13y2 − 3y − 5
Aneli [31]

Keywords:

<em>Division, quotient, polynomial, monomial </em>

For this case we must solve a division between a polynomial and a monomial and indicate which is the quotient.

By definition, if we have a division of the form: \frac {a} {b} = c, the quotient is given by "c".

We have the following polynomial:

65y ^ 3 + 15y ^ 2 - 25y that must be divided between monomy5y, then:

C (y) represents the quotient of the division:

C (y) = \frac {65y ^ 3 + 15y ^ 2 - 25y} {5y}

C (y) = \frac {65y ^ 3} {5y} + \frac {15y ^ 2} {5y} - \frac {25y} {5y}

C (y) = 13y ^ 2 + 3y-5

Thus, the quotient of the division between the polynomial and the monomial is given by:

C (y) = 13y ^ 2 + 3y-5

Answer:

The quotient is: C (y) = 13y ^ 2 + 3y-5

Option: A
