Answer:

B

Step-by-step explanation:

Answer:

8(a+4)= 8a + 32

Step-by-step explanation:

Answer:

The constant of proportionality is 3.

Step-by-step explanation:

Constant of proportionality is found by doing k = [tex]\frac{y}{x}[/tex]. Point (2,6) is on the line, so if we plug in point (2, 6) into the equation to solve for the constant of proportionality, we get [tex]k=\frac{6}{2}[/tex] or k = 3. The constant of proportionality is 3.

im kinda confused on what your asking but if you wanna know who then Milton Sirotta and our number system comes from Aryabhata

Step-by-step explanation:

Answer:

1) D.208

2) C.112

Step-by-step explanation:

so basically for 1 you solve the area for all the shapes you see in the net using the equation l*w=a and add them together

l= length

w=width

a=area

4*8=32

4*8=32

6*4=24

6*4=24

6*8=48

6*8=48

48+48+24+24+32+32=208

208[tex]cm^{2}[/tex]

for number 2 since it's lateral surface area, you wanna find the area of all the shape in the net except for the square in the middle.

for the triangles you're gonna wanna use the equation 1/2b*h=a

b= base

h=height

a=area

7*4=28

7*4=28

7*4=28

7*4=28

28*4=112

Answer:

The total area is 66

Answer:

D 13

Step-by-step explanation:  L+L+W+W=Perimeter

2(1/4x)+2(2x+1)=4.5x+2            

4.5x+2=29        Subtract 2

4.5x=27             Divide by 4.5

x=6                                                            1/4(6)= 1.5 W=1.5      1.5(2)=3

                                                                 2(6)+1=13                  13(2)=26

                                                                                   26+3=29inches perimeter

Answer:

A: 12 4/9

Step-by-step explanation:

1/4x (2x + 1) = 29 (Combine like terms, NOT distributive property!!!)

   2 1/4x + 1 = 29

               - 1    - 1

2 1/4 / 2 1/4x = 28 / 2 1/4

                  x = 12 4/9

x = 12

Answer:

C

Step-by-step explanation:

In A, its :            10 - 3 x (4-5)

In B, it's :            (10-3) + 5

In D it's:            Nonsense

The only true answer is C:      (10-3)  x 4 + 5

Answer:

B) 20

Step-by-step explanation:

30 = 150% × Y

30 = 150/100 x Y

Y = 30 x 100 divided by 150

Y = 20.

Faster way: 30 x 100 divided by 150.

Answer:

149

Step-by-step explanation:

Find area of both triangles 6 x 6 because there are 2

Triangles area 36

Rectangle area= 9.25 x 20=185

Subtract  185-36=149

Answer and Step-by-step explanation:

First, you would find the area of the un-shaded portion, then we would add those together and subtract it from the area of the entire rectangle.

Base and Height (of triangle) is 6.

[tex]\frac{6*6}{2}[/tex] = 18

[tex]\frac{6*6}{2}[/tex] = 18

Area of Rectangle (length times width).

[tex]9\frac{1}{4}[/tex] × 20 = 185

185 - 36 = 149

A dot plot titled Number of Hours Spent on Homework goes from 1 to 6. There is 1 dot above 1, 5 dots above 2, 6 dots above 3, 4 dots above 4, 1 dot above 5, and 1 dot above 6. What is a dot plot and how do you read it? Check all that apply. A dot plot is a simple plot that displays data values as dots above a number line. Dot plots show the frequency with which a specific item appears in a data set. 3 students spent 4 hours on homework. 5 students spent 2 hours on homework. Dot plots show the distribution of the data. Students spent 1 to 6 hours on homework.

Step-by-step explanation:

Answer:

Length of the Area = 50mtrs

Width of the Area  = 20mtrs

Step-by-step explanation: Let the x be the length and y be the width of the Area. So we can write x = 2 y + 10 and x y = 1000 or ( 2 y + 10 ) y = 1000 or 2 y 2 + 10 y = 1000 or 2 y 2 + 10 y − 1000 = 0 or y 2 + 5 y − 500 = 0 or y 2 + 25 y − 20 y − 500 = 0 or y ( y + 25 ) − 20 ( y + 25 ) = 0 or ( y + 25 ) ( y − 20 ) = 0 or y + 25 = 0 or y − 20 = 0 or y = − 25 Invalid value contains negative sign or y = 20 So Width of the Area is 20 ----------Ans By plugging the value of y = 20 in the eqn x = 2 y + 10 we get Length of the Area = 2 × 20 + 10 = 50 -------------Ans
