Answer:

160 square units

Step-by-step explanation:

We need to find the surface area of this figure, which is basically the areas of all the exterior sides.

Looking at the pyramid, we notice that we have 4 congruent triangles and 1 square.

Triangles:

The area of a triangle is denoted as A = (1/2) * b * h, where b is the base and h is the height. Here, the base is 8, so b = 8, and the height is 6, so h = 6. Plug these values in to get the area of one triangle:

A = (1/2) * b * h

A = (1/2) * 8 * 6 = (1/2) * 48 = 24

The area of one triangle is 24 square units, so the area of 4 is 24 * 4 = 96 square units.

Square:

The area of a square is denoted by: A = s * s = s². Here, s = 8, so plug that in:

A = s²

A = 8² = 8 * 8 = 64

The area of the square is 64 square units.

Now add up the areas of the triangles and square:

96 + 64 = 160 square units

The surface area is 160 square units.

Answer:

160

Step-by-step explanation:

Surface area = 4 triangles + square

4(½ × 6 × 8) + 8²

96 + 64

160 units²

Answer:

The answer should be 9in.

Answer:

30 percent

Step-by-step explanation:

12/40=0.3

0.3=30 percent

Answer:

30%

Step-by-step explanation:

To find a percent, use this equation:

x/100 = n/t

where x is the percent, n is the select number of things, and t is the total number of things

Substitute:

x/100 = n/t

x/100 = number of shots Marin made/number of shots attempted

x/100 = 12/40

Now, we need to cross multiply, or multiply the numerators by the denominators of the other fraction, and vice versa.

Multiply:

x/100 = 12/40

x(40) = 40x

100(12) = 1200

40x = 1200

Now, divide both sides of the equation to find the value of x.

Divide:

40x = 1200

/40     /40

x = 30

Now we have the percent is fraction form: 30/100

To make it a percentage, simply take the numerator and add the % sign.

Therefore, Martin made 30% of his shots.

Answer: 4/9

Step-by-step explanation:

9^2+B^2= 97

81+b^2=97

b^2=16

B=4

opposite=4

adj=9

tan= opposite/adj = 4/9

Answer:

81 m².

Step-by-step explanation:

To find the area of a square, you will simply need to do the side-length squared, or [tex]A= l^{2}[/tex].

If the side-length is 9, we can do:

A = 9²

A = 81 m²

Step-by-step explanation:

Step 1:  Find the area

An area of a square has a formula of → [tex]A= s^2[/tex]

[tex]A = 9 * 9[/tex]

[tex]A = 81[/tex]

Answer:  [tex]Area=81m^2[/tex]

Answer:There are many different answers :-)    but 100, 40, 40 is one

Step-by-step explanation:

There are quite a few answers, but you need to make sure 1 angle is greater than 90 degrees.  The remaining two angles should add up to less than 89 degrees and all 3 angles should total 180 degrees.

i.e. 100, 40, 40

Answer:

Answer:

He bought six cups of milk

Step-by-step explanation:

1 quart is 4 cups and one eighth of a gallon is 2 cups.

Answer:

250,000 to 700,000 parts

Step-by-step explanation:

For the lower ratio of 0.5, we have to get 0.5 flouride parts/1 gallon of water equivalent to (some fluoride parts)/ (500,000 gallons of water). we can multiply 500,000 by 0.5 to get 250,000 as our lower limit. Similarly, we can multiply 500,000 by 1.4 to get 700,000 as our upper limit

Answer:

V = 54316.7 in³

Step-by-step explanation:

V = 54316.7463 in³

The solution is, the volume of a hemisphere with a radius of 29.6 in, rounded to the nearest tenth of a cubic inch is, 54289.2 cubic inches.

In mathematics, volume is the space taken by an object. Volume is a measure of three-dimensional space. It is often quantified numerically using SI derived units or by various imperial or US customary units. The definition of length is interrelated with volume.

here, we have,

a hemisphere with a radius of 29.6 in,

i.e. The radius is 29.6.

now, we know that,

the volume of a hemisphere = 2/3 * pi* r^3

using the formula, we get,

V = 2/3 * 3.14 * 29.6³

   =54289.2100267

now, rounded to the nearest tenth  we get,

54289.2100267 ≈ 54289.2

The volume of the hemisphere should be 54289.2 cubic inches.

Answer:

C. -5

Step-by-step explanation:

14x and 6y both have variables attached to them

the most basic form for a function like this is ax+by+c

the definition of constant is a fixed value. the reason your constant has to be a solo number, not attached to a variable, is that these variables change the number!! so, -5, the only number that won't change in the function, is the constant.
