Step-by-step explanation:

the formula for the area of a triangle is base times height divided by 2

A=bh/2

the base in this triangle is 15 and the height is 4

(15)(4)/2

60/2

The store salsa jars have a height of ten centimeters and a radius of five centimeters. If there is only four centimeters of sal

Romashka-Z-Leto [24]

Answer:

$V=471.24cm^{3}$ (simplified)

$V=150\pi cm^{3}$ (in terms of pi)

Step-by-step explanation:

Since the salsa jar is basically a cylinder, to solve this we are using the formula for the volume of a cylinder:

$V=\pi r^{2} h$

where

$V$ Is the volume of the cylinder (salsa jar)

$r$ is the radius of the cylinder (salsa jar)

$h$ is the height of the cylinder (salsa jar)

We know from our problem that height of the full salsa jar is 10 centimeters; we also know that that there are only 4 centimeters of salsa left in the salsa jar. So, to find the the height of the missing salsa, we just need to subtract the height of the salsa from the height of the full salsa jar: $h=10cm-4cm=6cm$ . Since the radius of the salsa jar never changes, $r=5cm$ .

Now we can replace the values in our volume formula to find how much salsa is missing from the jar:

$V=\pi r^{2} h$

$V=\pi (5cm)^{2} (6cm)$

$V=\pi (25cm^{2})(6cm)$

$V=150\pi cm^{3}$

$V=471.24cm^{3}$

We can conclude that there are 471.24 cubic centimeters missing from the jar, or in terms of pi: $150\pi cm^{3}$ .

Find the volume of the pyramid

Vilka [71]

Volume is a three-dimensional scalar quantity. The volume of the right-triangular pyramid is 1.008 m³.

<h3>What is volume?</h3>

A volume is a scalar number that expresses the amount of three-dimensional space enclosed by a closed surface.

The volume of a right-triangle pyramid is one-third of the product of its base area and its height. Therefore, the volume is,

Volume = (1/3) × 0.5 × 1.4 × 1.8 × 2.4

= 1.008 m³

Hence, the volume of the right-triangular pyramid is 1.008 m³.

A library has five copies of a certain textbook on reserve of which two copies (1 and 2) are hardcover books and the other three

Gre4nikov [31]

Answer and Step-by-step explanation:

(a) Since the student have to stop when he gets to w softcover book, then the sample space should always stop at either 3 or 4 or 5. If the students examines the books randomly and stops at a softcover book, here are the possible ways he could carry this out,

S = {3, 4, 5, 13, 14, 15, 23, 24, 25, 123, 124, 125, 213, 214, 215}

2. Since only one book is to be examined then the student must check only one softcover book and end the examining. To do this, either he examines just 3 or 4 or 5. Therefore,

A = {3, 4, 5}

3. We need to pick the possibilities from the sample space that shows that the examining ended at book 5. Therefore,

B = {5, 15, 25, 125, 215}

4. We need to pick possibilities from the sample space that shows that book 1 was not examined. Therefore,

C = {3, 4, 5, 23, 24, 25}
