Answer 1

Answer:

Triangular prism 1:    132

Triangular prism 2:   828

Step-by-step explanation:

1) triangle+triangle+rectangle+rectangle+rectangle

A of triangle=3*4 divided by 2

12/2= 6

since there are 2 triangles we do 6*2= 12

A of rectangle 1= 10*5= 50

A of rectangle 2= 10*4= 40

A of rectangle 3= 10*3= 30

so SA of whole figure is 12+50+40+30= 132

2) triangle+triangle+rectangle+rectangle+rectangle

A of triangle=9*12 divided by 2

108/2=54

since there are 2 triangles we do 54*2=108

A of rectangle 1= 9*20=180

A of rectangle 2= 15*20=300

A of rectangle 3= 12*20= 240

so SA of whole figure is 108+180+300+240=828

The length of a rectangle is 1 foot more than twice the width. The area is 55 square feet. Find the perimeter of the rectangle.

Answers

Answer:

5 ft and 11 ft

Step-by-step explanation:

l= 2w+1

A=lw= 55

w(2w+1)=55

2w²+w-55=0

integer solution of quadratic equation is:

w=5 ft

l= 2*5+1=11 ft

Answer:

32 feet

Step-by-step explanation:

Start by creating your 2 equations

l = 2w + 1

l * w = 55

Plug in l, the isolated variable

(1 + 2w)w = 55

w + 2w² = 55

2w² + w -55 = 0

( − 5 ) ( 2 + 1 1 ) = 0

w= 5

w= -11/2 <- the width can't be negative so this one is out

Plug width into the area formula to find length

l * 5 = 55

l = 11

Find the Perimeter

2(11) + 2(5)

22 + 10 = 32

Mrs Washington has a greater ratio of band students to chorus students.  I know my answer is correct because I compared the ratio of the band to chorus students where the Band was the same. When Band to chorus had 10:15  students for Washington's class, and Band to chorus had 10:14 in Utley's class. This means That Washington had more students.

What is the sum of the measures that represent the measures of each angle if m∠ABC=2x°, m∠CBD=3x°, and m∠EBD=4x°?


What is the measure of each angle?


Explain how an equation can be written to find m∠CBD.

Answers

Answer:

∠ABC= 40°  ∠CBD=60°  ∠EBD=80°

Step-by-step explanation:

Step 1: 2x+3x+4x=180

          A straight line is 180 degree's, and to get the value of the different angles, you have to add the three angle measures.

Step 2: 9x=180

            Combine like terms

Step 3: x=20

            Divide/ Isolate the variable

Step 4: 2(20)=40   3(20)=60    4(20)=80

What is (-3,0) be 90 degrees clockwise on a graph?

Answers

Answer:

(0, 3)

Step-by-step explanation:

Visualize this problem as being based on a circle of radius 3.  (-3, 0) lies on this circle, straddling the x-axis.

Now if we rotate that radius (connecting the (0, 0) to (-3, 0) clockwise, the point (-3, 0) becomes the point (0, 3).

the answer is (0,3) because (x,y) changes to (-y,x) when a 90 degree clockwise turn happens
