Jada is using pyramid-shaped piece of foam with the dimensions shown below for a model she is making. She has to paint the triangular surfaces for her model. The slant height of each triangular face is 9mm. The base will NOT be painted. Find the SURFACE AREA of the pyramid that has to be painted.

Answer:

Answer A is the correct answer.

Answer:

14.1 =x

Step-by-step explanation:

Since this is right triangle, we can use trig functions

sin theta = opp/ hypotenuse

sin 42 = x /21

21 sin 42 = x

14.05174273 =x

Rounding to the nearest tenth

14.1 =x

Answer:

x = 14.1 (Rounded to the nearest tenths)

Step-by-step explanation:

Since the opposite side of the angle given needs to be found out and hypotenuse, Sin ratio would be used;

Sin(42) = [tex]\frac{x}{21}[/tex]

=> Now multiply 21 on both sides of =, in order to isolate x;

Sin(42) * 21 = x

14.1 = x

Answer:

scale factor = length of image

corresponding length of object

= 32

8

= 4

The scale factor of the dilation of the given object is 4.

The scale factor of dilation of an object is determined by taking the ratio of image length to corresponding object length.

The scale factor of the dilation of the object is calculated as follows;

[tex]S.D = \frac{32\pi \ cm^2}{8\pi \ cm^2} \\\\S.D = 4[/tex]

Thus, the scale factor of the dilation of the given object is 4.

Answer:

5 days

Step-by-step explanation:

dogs, combined, eat 80 ounches of food daily

there are 16 ounces in one pound so there are 25x16, or 400 ounces, in a 25-pound bag

400/80 = 5

25-pound bag would last 5 days

One bag of dog food volunteered by Amelia, Which have quantity of 25 pounds  will last for 5 days.

What is ratio?

Ratio is mathematical term, which we use for comparing two or more terms. basically it indicates that how much big or small is number in compared to another.

Given that,

Every day, Amelia puts out 10 ounces of food for each of the 8 dogs.

Dog food comes in 25-pound bags.

And it is know that,

1 pound = 16 ounce;

so by that way it can state that,

Dog food for 25-pound bag will be equal to;

25*16

400 ounce.

Everyday requirement of dog food is 8*10 = 80 ounce/day

Number of days food will  last= Available quantity/Everyday requirement

Number of days food will  last= 400/80

Number of days food will  last= 5 days

Hence, One bag of food will be enough for 5 days.

Answer:

Below in bold.

Step-by-step explanation:

When x = 4 the denominator = 0 so the vertical asymptote is x = 4.

When x approaches negative and positive infinity  f(x) approaches zero  so the horizotal asymptote is y = 0 ( the x-axis).

Where the above is square, the coordinates are: (4, 7). This is obtained by simply tracing the A-D in equal distance with B and C.

A coordinate system in geometry is a system that employs one or more integers, or coordinates, to define the position of points or other geometric components on a manifold such as Euclidean space.

A coordinate system is a framework for specifying the relative positions of objects in a specific region, such as an area on the earth's surface or the whole earth's surface. A geographic coordinate system determines locations on the world by using a three-dimensional spherical surface.

The table in the exercise can be completed with the next results:

Step-by-step explanation:

As in the exercise Janice is 7 years older than Tam, to obtain the result in the table, you must add 7 to each age in the column x, with this we can make the next formula:

Remember that x is Tam's age, and y is Janice's age, so, you must replace the x variable in each case to obtain the result to y:

When x is 2:

When x is 4:

When x is 6:

When x is 8:

At last, to obtain the graph you can use the formula made: y = x + 7, and you'll obtain a graph like the attached picture, where each time x obtain a unit, the y variable obtain a unit too maintaining the diference of 7.

Answer:

Standard form = 606000

Scientific notation = 6.06*10^5

Step-by-step explanation:

Given the expression

(8.08×106)×(7.5×10−2)

This can also be expressed as;

(8.08*7.5) * (10^6*10^-2)

= 60.6*10^4

= 606000

express in scientific form;

606000

= 60.6*10^4

= 6.06*10^1*10^4

= 6.06 * 10^5

Answer:

1/6

Step-by-step explanation:

3 out of 18 marbles are green. 3/18 can be reduced to 1/6 because both 3 and 18 are divisible by 3.

3/3=1

18/3=6

1/6

The probability of picking a green marble is 1/6.

To find the probability of picking a green marble, we need to consider the total number of marbles and the number of green marbles in the jar. The jar contains a total of 18 marbles, and out of these, there are 3 green marbles.

The probability of an event happening is calculated by dividing the number of favorable outcomes (in this case, the number of green marbles) by the total number of possible outcomes (the total number of marbles in the jar).

So, the probability of picking a green marble can be written as:

P(green marble) = Number of green marbles / Total number of marbles

Substituting the values, we get: P(green marble) = 3 / 18

To simplify this fraction, we can divide both the numerator and denominator by their greatest common divisor, which is 3. Dividing both 3 and 18 by 3, we get: P(green marble) = 1 / 6

Therefore, the probability of picking a green marble from the jar is 1/6. This means that if you randomly pick a marble from the jar, there is a 1 in 6 chance that it will be green.
