Answer:

The volume of the triangular prism is 2.76\ m^{3}

Step-by-step explanation:

we know that

The volume of the triangular prism is equal to

V=BH

where

B is the area of the triangular base

H is the height of the prism

In this problem we have

B=2.3\ m^{2}

H=1.2\ m

substitute the values

V=(2.3)(1.2)=2.76\ m^{3}

What is the solution to this equation ?<br><br><br> x + 9 = -4
PolarNik [594]

Isolate the x. Note the equal sign. What you do to one side, you do to the other.

Subtract 9 from both sides

x + 9 (-9) = -4 (-9)

x = -4 - 9

x = -13

-13 is your solution

hope this helps

Drag the tiles to the correct boxes to complete the pairs. Add each pair of monomials and match it to the correct sum. -15u3 + 5
Grace [21]

Consider the given monomials. Let us determine the sum of these monomials,

1. -15u^3+5u^3

= -10u^3

Therefore, the sum of the given monomials is  -10u^3.

2. 10u^3+(-5u^3)

= 10u^3-5u^3

= 5u^3

Therefore, the sum of the given monomials is  5u^3.

3. 10u^3+5u^3

= 15u^3

Therefore, the sum of the given monomials is  15u^3.

4. 5u^3+(-10u^3)

= 5u^3-10u^3

= -5u^3

Therefore, the sum of the given monomials is  -5u^3.

Solve for x in the triangle<br> A 25.6<br> B 27.8<br> C 45.6<br> D 64.4
labwork [276]

Answer:

The measure of angle x is 64.4\°

Step-by-step explanation:

To find the measure of angle X, apply the law of cosines

The law of cosines states that

c^{2}=a^{2}+b^{2}-2(a)(b)cos(C)

In  this problem we have

a=19\ cm

b=25\ cm

c=24\ cm

C=x\°

substitute

24^{2}=19^{2}+25^{2}-2(19)(25)cos(C)

576=986-950cos(C)

cos(C)=(986-576)/950

C=arccos[(986-576)/950]=64.4\°

Therefore

The measure of angle x is 64.4\°
