What is the volume of this pyramid? 945 cm³ 1260 cm³ 1890 cm³ 2520 cm³ A pyramid with a right triangular base. The right triangu
notsponge [240]

Answer:

The volume of the pyramid is 1,260\ cm^{3}

Step-by-step explanation:

we know that

The volume of the triangular pyramid is equal to

V=\frac{1}{3}BH

where

B is the area of the triangular base

H is the height of the pyramid

step 1

Find the area of the base B

B=\frac{1}{2}bh

we have

b=14\ cm

h=18\ cm

substitute

B=\frac{1}{2}(14)(18)=126\ cm^{2}

step 2

Find the volume

we have

B=126\ cm^{2}

H=30\ cm

substitute

V=\frac{1}{3}BH

V=\frac{1}{3}(126)(30)=1,260\ cm^{3}

equation in slope-intercept form is:

y=9x+7

Step-by-step explanation:

The general form of slope-intercept form is:

y=mx+b

where m is the slope and b is the y-intercept

In the question we are given slope m=9 and a point(0,7)

We will find b i.e y-intercept

y=mx+b\\7=9(0)+b\\7=0+b\\b=7

So, value of b=7 and value of slope m=9

So, equation in slope-intercept form is:

y=9x+7

Keywords: slope-intercept form

Answer: 15\times\frac{1}{2}

Explanation:

Multiplying by 1/2 is the same as dividing by 2.

For example, if you have 10 slices of cake and 2 friends, then each friend gets 10/2 = 5 slices. We could also say 10\times \frac{1}{2} = 5

The fraction 1/2 converts to the decimal form 0.5, which means 10 \times \frac{1}{2} = 10*0.5

Name one possible cross section of a sphere
Lisa [10]
A "cross section" is basically the two-dimensional face that you get when you cut a three-dimensional figure a certain way.  For example, imagine you're buttering your bread.  When you cut a pat of butter off, what shape is left on the butter?  A square!

So, imagine cutting a ball in half.  What shape is left?  A circle!

Answer: circle
