A 12ft. ladder is leaned against a wall. If the base of the ladder is 5ft. from the wall, how high up on the wall does the ladder reach?

Answers

Answer:

use Pythagoras theorem

[tex] {a}^{2} + {b}^{2} = {c}^{2} \\ \\ a = 5 \\ b = (required \: lenth) \\ c = 12 \\ \\ { {5}^{2} } + {b}^{2} = {12}^{2} \\ {b}^{2} = {12}^{2} - {5}^{2} \\ b = \sqrt{119} \\ b = 10.90871211[/tex]

Pythagorean Theorem

x^2 + 5^2 = 12^2

x^2 +25 = 144

x^2 = 119

x = √199 or 10.9087121146

Jenna wants to wrap a shipping box shaped like a rectangular prism. The box is 20 inches tall and has a square base with sides that each measure 3 inches. How much paper will she use?

Answers

Answer:

23 inches

Step-by-step explanation:

258in squared of wrapping paper.

Explanation:

For this question, we are trying to find the surface area of the rectangular prism, not the area inside the rectangular prism because we are wrapping the box up.

So, If we break up the rectangular prism, we will get 4 rectangles that are 20 inches by 3 inches, and 2 squares (the base and the top) that are 3 inches by 3 inches.

What we have to do know is find the area of all these pieces, then add them together.

So for the 4 rectangles:

A = l x w
= 20 inches x 3 inches
= 60 inches

Since there’s 4 rectangles we do:
60 x 4 = 240 inches

For the 2 Squares:

A = l x w
= 3 inches x 3 inches
= 9 inches

since there’s 2 squares we do:
9 x 2 = 18 inches

Then we can add these totals up for the total surface area:

240 + 18 = 258 inches squared

( brainlies ) Can somebody help me with this?

Answers

Answer:
(a)

Area: 930 meters(m)

Perimeter: 122 meters(m)

(b)

Area: 616 centimeters(cm)

Perimeter: 116 centimeters(cm)

(c)

Area: 1008 millimeters(mm)

Perimeter: 128 millimeters(mm)

Explanation:

Area = length x width

Perimeter = length+width+length+width

Area for (a) is then 31 times 30 = 930
Area for (b) is then 44 times 14 = 616
Area for (c) is then 36 times 28 = 1008

Perimeter for (a) is 31+30+31+30=122

Perimeter for (b) is 44+14+44+14=116

Perimeter for (c) is 36+28+36+28=128

Answer:

P = 122 | A = 930P = 116 | A = 616P = 128 | A = 1008

Solve(perimeter) ➕2 · (30 + 31) = 1222 · (14 + 44) = 1162 · (28 + 36) = 128

[tex]\sf Formula[/tex]

P = 2 × ([tex]l[/tex] + [tex]w[/tex])

Solve(area) ❎31 · 30 = 93044 · 14 = 61636 · 28 = 1008

[tex]\sf Formula[/tex]

A = [tex]w[/tex] × [tex]l[/tex]

Answer:

the square pyramid has a base that is 4 units on each side. The height of each triangular face is 4 units.

Step-by-step explanation:

for the base count the boxes on one side. For the height count from the base of the pyramid to the point of the triangular faces.

Answer:

Blank 1: Four

Blank 2: Three

Step-by-step explanation:

You can solve both by looking at the graph, no formulas needed.

Blank 1: The base is the square in the middle (in this case). If you're ever unsure, the name of the shape usually names the base. It's called a "square pyramid" which means the base is square.

Now, we know it's just asking for how many units each side of the square is. Because this is a square, all sides are the same, so the amount of units is the same. If you count the units on one side, it's four.

Blank 2: The "triangular face" just means the triangle. The height of the triangle is found by counting the units of the tallest part. The tallest part is the middle. The middle is 3 units tall.

Hope this helped!
