Hello.
The surface area of a rectangular prism can be found by adding up the areas of all the faces. Additionally, since this is a rectangle, opposite sides will be of the same area, meaning that the surface area of a rectangular prism can be represented with the following equation.
[tex]SA=2(hw)+2(lw)+2(hl)[/tex]
Now let's plug in the dimensions of the rectangular prism.
[tex]SA=2(2*6)+2(6*3)+2(2*3)[/tex]
[tex]SA=72[/tex]
As for the units, the dimensions of the rectangular prism are given in centimeters, so our area will be in centimeters squared, as we are working with area.
Hope this helps!
Answer:
surface area = 72 cm²
surface area units = cm²
Step-by-step explanation:
surface area = 2(6x3 + 2x3 + 6x2) = 72 cm²

a= 540/5 = 108 (one interior angle)
x + a = 180 (linear pair)

To find the missing leg, use the following formula:
b = √[tex]c^{2} - a^{2}[/tex]
b = √[tex]37^{2} - 28^{2}[/tex]

The function f(x)=2x^2+x+5 represents the number of jars of pickles, y in tens of jars, denise expects to sell x weeks after launching her online store. What is the average rate of change over the interval 1<\= x <\= 2? Pls help quick!
Answers
Answer:
The average rate of change is 7.
Step-by-step explanation:
We are given the function:
[tex]f(x)=2x^2+x+5[/tex]
Which represents the number of jars of pickles, y (in tens of jars), Denise expects to sell x weeks after launching her store.
We want to find the average rate of change over 1 ≤ x ≤ 2.
Essentially, we want to find the slope over f(1) and f(2).
Thus, first evaluate the two endpoints:
[tex]f(1)=2(1)^2+(1)+5=2+1+5=8[/tex]
And:
[tex]f(2)=2(2)^2+2+5=8+2+5=15[/tex]
This gives us the two points (1, 8) and (2, 15).
Then the average rate of change will be the slope between the two:
[tex]\displaystyle m=\frac{15-8}{2-1}=7[/tex]
With units, this means that over the first and second week, Denise sold on average 70 jars of pickles per week.

Melanie gave her mother a bouquet of 24 flowers. The bouquet was made up of roses, carnations, and daisies. There were twice as many daisies as roses. There were three times as many carnations as roses. How many of each kind of flower was in the bouquet?
Answers
Answer:
Roses = x = 4
Carnations = y = 12
Daisies = z = 8
Step-by-step explanation:
The bouquet was made up of roses, carnations, and daisies.
Let us represent:
Roses = x
Carnations = y
Daisies = z
Melanie gave her mother a bouquet of 24 flowers.
Hence,
x + y + z = 24...... Equation 1
There were twice as many daisies as roses.
z = 2x
There were three times as many carnations as roses.
y = 3x
Therefore, we substitute 2x and 3x for z and y respectively in Equation 1
x + y + z = 24...... Equation 1
x + 3x + 2x = 24
6x = 24
x = 24/6
x = 4 roses
Solving for y
y = 3x
y = 3 × 4
y = 12 Carnations
Solving for z
z = 2x
z = 2 × 4
z = 8 Daisies
How many of each kind of flower was in the bouquet?
Therefore,
Roses = x = 4
Carnations = y = 12
Daisies = z = 8
Melanie gave her mother a bouquet of 24 flowers which has three kinds of flowers
The number of roses in the bouquet = 4
The number of carnations in the bouquet = 12
The number of daises in the bouquet = 8
Melanie gave her mother a bouquet of 24 flowers.
The bouquet was made up of roses, carnations, and daisies.
Let there be x roses
Let there be y carnations
Let there be z daises in the bouquet
So the total number of flowers in the bouquet is given by equation (1)
[tex]\rm x +y + z = 24........(1)[/tex]
There were twice as many daisies as roses.
So
[tex]\rm z =2x ....(2)[/tex]
Also , There were three times as many carnations as roses
[tex]\rm y = 3x ........(3)[/tex]
From equations (1) , (2) (3) we get
[tex]\rm z \; and \; y \; from \; (2)\; and \; (3)\; in\; (1) \; we\; get \\x + 2x +3x = 24\\6x = 24\\x= 24/6\\x = 4[/tex]
So
The number of roses in the bouquet = 4
The number of carnations in the bouquet = 12
The number of daises in the bouquet = 8

Harold is designing a patio with congruent square concrete tiles. He has 72 tiles. Use grid paper to model all the possible rectangular patios Harold could build. Label the dimensions in units. Which patio has the greatest perimeter? The least perimeter?
Answers
Answer:
(a) The possible dimensions are:
1 unit by 72 units; 2 units by 36 units; 3 units by 24 units; 4 units by 18 units; 6 units by 12 units; 8 units by 9 units
(b): Patio with greatest and the least perimeter
The dimension with the greatest perimeter is: 1 by 72
The dimension with the least perimeter is: 8 by 9
Step-by-step explanation:
Given
[tex]Tiles = 72[/tex]
Solving (a): Possible rectangular models
To do this, we simply list out the possible factor pairs of 72.
So, we have:
1 unit by 72 units; 2 units by 36 units; 3 units by 24 units; 4 units by 18 units; 6 units by 12 units; 8 units by 9 units
Solving (a): Models with the least and the greatest perimeter
Perimeter (P) is calculated using:
[tex]P = 2 * (L + W)[/tex]
So:
1 unit by 72 units;
[tex]P = 2 *(1 + 72) = 146 units[/tex]
2 units by 36 units;
[tex]P = 2 *(2 + 36) = 76 units[/tex]
3 units by 24 units;
[tex]P = 2 *(3 + 24) = 54 units[/tex]
4 units by 18 units;
[tex]P = 2 *(4 + 18) = 44 units[/tex]
6 units by 12 units;
[tex]P = 2 *(6 + 12) = 36 units[/tex]
8 units by 9 units
[tex]P = 2 *(8 + 9) = 34 units[/tex]
From the calculations above:
The dimension with the greatest perimeter is: 1 by 72
The dimension with the least perimeter is: 8 by 9

Answers
Answer:
3900 feet
Step-by-step explanation:
Steps to answer this question
We are to convert yards to feet Multiply laps sum by two to determine the number of laps he swam in two weeksthen multiply figures gotten from 1 and 21 yard = 3 foot
25 yards = 25 x 3 = 65 foot
total yards swam = 30 x 2 = 60
60 x 65 = 3900

What is an expression?Mathematical actions are called expressions if they have at least two terms that are related by an operator and include either numbers, variables, or both. Adding, subtraction, multiplying, and division are all reflection coefficient operations. A mathematical operation such as reduction, addition, multiplication, or division is used to integrate terms into an expression.
As per the data given in the question,
The total amount Kiran is having in the bank = $100
He needs to have at least $25 in the account at the end of the year.
So, the money he can spend in a year = $100 - $25 = $75
1 year = 12 months
So, the amount of money spent per month will be,
75/12 = $6.25

Answer:
x = 3.6
Step-by-step explanation:
It can be helpful to write down corresponding sides and their measures.
AB = 5, PQ = 6
BC = 3, QR = x
CD = 2, RS = 2.4
DA = 4, SP = 4.8
Then you can look for easy ways to find x. You can tell from this table that all of the values in PQRS are 6/5 = 1.2 times the corresponding values in ABCD.
Then ...
QR = 1.2×BC = 1.2×3
QR = x = 3.6
_____
Other ways you can figure x are ...
x/BC = PQ/AB
x = (BC)(PQ/AB) = 3(6/5) = 3.6 . . . . the method we used
__
x/RS = BC/CD
x = 2.4(3/2) = 3.6
__
x/SP = BC/DA
x = 4.8(3/4) = 3.6

Angle O=64
Side m=7.3159882(rounded if needed)
Side n=16.68902(round if needed)
We are given
Angle M which equal 26.
Angle N equals 90 degrees
Side MN which equal 15.
We are asked to find all the missing elements of the triangle.
Angle O can be found using triangle interior theorem so we can add 90+26+x =180 to find the value that satisfies the x value.
[tex]90 + 26 + x = 180[/tex]
[tex]116 + x = 180[/tex]
[tex]x = 64[/tex]
Angle O=64 degrees
We can find side m by doing law of sines.
[tex] \frac{on}{ \sin(26) } = \frac{mn}{ \sin(64) } [/tex]
[tex] \frac{on}{ \sin(26) } = \frac{15}{ \sin(64) } [/tex]
[tex]on = \frac{15}{ \sin(64) } \times \sin(26) [/tex]
which is 7.315(round if neeeded).
We can find side n using pythagorean theorem,
[tex] {15}^{2} + {7.3}^{2} = {n}^{2} [/tex]
[tex]225 + 53.29 = {n}^{2} [/tex]
[tex] \sqrt{278.29} [/tex]

From a horizontal distance of 80.0 m, the angle of elevation to the top of a flagpole is 18 degrees. Calculate the height of the flagpole to the nearest then of a meter.
Answers
Answer: 84.1m
Step-by-step explanation:
Let the height of the flagpole be represented by x.
First and foremost, we have to know that the cosine of 18° = 0.9511.
The equation to get the height will then be:
0.9511 = 80/x
Cross multiply
(0.9511 × x) = 80
0.9511x = 80
Divide both side by 0.9511
0.9511x/0.9511 = 80/0.9511
x = 84.1
The height of the flagpole is 84.1m
