A. V= l x b x h
= 5cm x 4cm x 10cm
= 200 squared centimetres

C. V= S squared x h divided by 3
= 15cm x 17cm divided by 3
= 85 squared centimetres

D. V= b x h x l divided by 2
= 8cm x 10cm x 13cm divided by 2
= 520 cubed centimetres

Well am not sure about the other two but I hope this helps ya

6. Find all missing angles m<1 m<2 m<3​
masha68 [24]

Answer:

1. 128

2. 52

3. 47

4. 133

5. 81

Step-by-step explanation:

1. <1 and <52 are same side interior angles, therefore supplementary. So they should add up to equal 180, this means that <1 is 180 - 52. Solve to get <1 is 128

2. <2 is an alternate interior angle to <52, this means that they are congruent. Since they are congruent, they have the same value of 52.

3. <3 is an alternate interior angle to <47, so they are congruent, this means that they both have a value of 47

4. <4 is supplementary to <3 so you can say that <4 is equal to 180 - 47. Solve this to get <4 is 133

5. <5, <52, and <47 are supplementary when you combine all three. So you can create an equation that says <5 is equal to 180 - 52 + 47. This gives you that angle 5 is 81.

Solve the system of equations using the elimination method. 2x − 3y = 50;7x + 8y = −10
lorasvet [3.4K]

Answer: C. (10, -10)

Step-by-step explanation:

Given

1) 2x-3y=50

2) 7x+8y=-10

Multiply both sides of 1) equation by 3.5

1) 3.5(2x-3y)=3.5×50

   7x-10.5y=175

2) 7x+8y=-10

Subtract 2) equation from the 1)

(7x-10.5y)-(7x+8y)=175-(-10)

-18.5y=185

y=-10

x=10

(10, -10)

Hope this helps!! :)
