Which simple solid looks like a square from above, a triangle from the front, and a triangle from the side?

Answer:

a) t = 0.54 seconds

b) t = 8 seconds

Step-by-step explanation:

Given in the question the equation

h = 40t - 5t²

where h is height in meters

            t is time in seconds

Time it took to reach 20 meters

20 = 40t - 5t²

-5t² + 40t - 20 = 0

by using quadratic formula for factorisation

t = 0.54 (upward motion)

or

t = 7.46 (downward motion)

b) Time it took to reach the ground

at ground h = 0

So,

0 = 40t - 5t²

t(40 - 5t ) = 0

t = 0 (at starting point)

or

40 -5t = 0

5t = 40

t = 40 /5

t = 8 seconds

Answer:

x > 18

Step-by-step explanation:

If you need to complete more than 18 repetitions, you would use the greater than sign.

You can tell if they're similar if they:

1) Have two of the same angles

2) If two pairs of corresponding angles in a pair of triangles are congruent.

3) If they are the same shape

with it's formula

Area of Triangle = (1/2)(ab)sin(C) – This formula is used when two sides and the angle in between them are known. It can be obtained from the basic formula, Area of Triangle = 0.5 × base × height. The height with respect to side 'a' can be written in as b×sin(C), where C is the angle between a and b.

Circumference = 2pi*r

22.6 = 2*3.14*r

22.6 = 6.28*r

r = ~3.6

Using that we can find area

A = pi*r^2

A = 3.14*3.6^2

A = 3.14*12.96

A = 40.6944 which is ~40.7in^2

The area of the circular plate with a circumference of 22.6 inches is 40.69 in².

The area of a circle can be found by using the formula given below:

Area = πr²

The circumference is given as 22.6. Therefore:

Circumference = 2πr

⇒ 22.6 inches = 2πr

⇒ 22.6 inches = 2*3.14*r

⇒ r = 22.6/(2*3.14) inches

⇒ r = 3.6 inches

We can use this r to find the area. The area of a circle is given by:

A = πr²

= 3.14*3.6*3.6 in²

= 40.69 in²

Therefore we have found the area of the circular plate with a circumference of 22.6 inches to be 40.69 in².

Step-by-step explanation:

The total time for the student's total trip is A = 58 minutes

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is = total time for the trip

Substituting the values in the equation , we get

The total length of the bus route is 57 minutes. The student is taking a trip for 2/3 of the total route length, which is (2/3) x 57 = 38 minutes

In addition to the time on the bus, the student must also walk 10 minutes to get to the bus and 10 minutes from the bus to his destination.

Therefore, the total time for the student's trip is:

38 minutes (on the bus) + 10 minutes (walking to the bus) + 10 minutes (walking from the bus) = 58 minutes

Hence , the time for student's trip is A = 58 minutes

2. 16 cm and 45 cm cone

3. 0.9 Fl oz

4. the cone still

Step-by-step explanation:

The volume of each vase can be determine by using volume formula of sphere, cone and cylinder.

(1) The volume of sphere is [tex]972\pi[/tex], volume of cone is [tex]960\pi[/tex] and volume of cylinder is [tex]1000\pi[/tex].

(2) You should purchase the cylinder vase.

(3) The largest vase hold [tex]40 \pi \:{\rm cm}^3[/tex] more than smallest vase.

(4) If the diameter decreases by 2 cm, then cone holds more water.

Given:

Diameter of cylinder is [tex]d=10 \:\rm cm[/tex].

Height of cylinder is [tex]h=40\:\rm cm[/tex].

Diameter of cone is [tex]d=16 \:\rm cm[/tex].

Height of cylinder is [tex]h=45\:\rm cm[/tex].

Diameter of sphere is [tex]d=45 \:\rm cm[/tex].

(1)

Calculate the volume of cylinder.

[tex]\begin{aligned}\mbox{Cylinder Volume} &= \pi r^2 h\\& = \pi(5)^2(40) \text{ cm}^3\\&= 1000 \pi \text{ cm}^3.\end{align}[/tex]

Calculate the volume of Cone.

[tex]\begin{aligned}\mbox{Cone Volume} &= \frac13 \pi r^2 h\\&= \frac13 \pi(8)^2(45) \text{ cm}^3\\&= 960 \pi \text{ cm}^3.\end{align}[/tex]

Calculate the volume of sphere.

[tex]\begin{aligned}\mbox{Sphere Volume} &= \frac43 \pi r^3\\&= \frac43 \pi (9)^3 \text{ cm}^3\\&= 972 \pi \text{ cm}^3.\end{align}[/tex]

(2)

Since the volume of cylinder is higher than the volume of sphere and cone. So, you should purchase cylinder vase.

(3)

The largest vase hold water more than the smallest vase is,

[tex]\text{Cylinder Volume} - \text{Cone Volume} = 1000 \pi \text{ cm}^3 - 960 \pi \text{ cm}^3 = 40 \pi \text{ cm}^3[/tex]

(4)

As per the question if diameter of each vase decreases by 2 cm then radius decreases by 1 cm.

Calculate the volume of cylinder.

[tex]\begin{aligned}\mbox{Cylinder Volume} &= \pi r^2 h\\&= \pi(4)^2(40) \text{ cm}^3\\&= 640 \pi \text{ cm}^3.\end{align}[/tex]

Calculate the volume of Cone.

[tex]\begin{aligned}\mbox{Cone Volume}&= \frac13 \pi r^2 h\\&= \frac13 \pi(7)^2(45) \text{ cm}^3\\&= 735 \pi \text{ cm}^3.\end{align}[/tex]

Calculate the volume of sphere.

[tex]\begin{aligned}\mbox{Sphere volume} &= \frac43 \pi r^3\\&= \frac43 \pi (8)^3 \text{ cm}^3\\&= 682 \frac23 \pi \text{ cm}^3.\end{align}[/tex]

➷The answer is that 20 goes into 16 1.25 times.

Explanation: You can use a calculator, and you just divide 20 by 16. Or, you can divide 20 and 16 both by 4. since you are dividing by four, and there are 5 fours in 20, you could know that 5*0.25 is 1.25, which is the answer. The fraction form is 1 1/4.

20 cannot go into 16 a whole number of times, but in terms of decimal division, 20 goes into 16 exactly 0.8 times.

The question asks how many times 20 can go into 16. In mathematical terms, this is asking for the result of dividing 16 by 20. Since 20 is larger than 16, 20 cannot go into 16 a whole number of times. However, if we are considering division in terms of fractions or decimals, 20 goes into 16 exactly 0.8 times because 16 divided by 20 equals 0.8.

Answer:

5/100, .05

Step-by-step explanation:

The decimal form remains 0.5, but when expressed with a denominator of 100, it becomes 50.0%.

To express 0.5 as hundredths in fraction form, you convert the decimal to a fraction with a denominator of 100. Since 0.5 is equivalent to 50%, you would write this as 50/100. This fraction can also be simplified to 1/2 by dividing both the numerator and the denominator by 50.

In decimal form, 0.5 is already represented as a decimal and does not require conversion. However, if we are to express it with a denominator of 100, we simply move the decimal point two places to the right (multiplying by 100), yielding 50.00, which can then be represented as 50.0% when expressing as a percent.

Final answer:

The area of a trapezoid with bases of 4 yards and 6 yards, and a height of 5 yards is calculated using the formula (1/2)*height*(sum of the bases). By substituting the given measurements, the area comes out to be 25 square yards.

Explanation:

The area of a trapezoid can be calculated using the formula: Area = ½×(height)×(sum of the bases). Given the measurements of a trapezoid with bases of 4 yards and 6 yards, and a height of 5 yards, we apply the formula:

Area = ½×(5 yards)×(4 yards + 6 yards)

First, sum the lengths of the bases:

4 yards + 6 yards = 10 yards

Then, substitute the sum of the bases and the height into the formula:

Area = ½×(5 yards)×(10 yards)

Area = ½×(50 yards²)

Area = 25 yards²

Therefore, the area of the trapezoid is 25 square yards.

Answer:

Part a) Higher fee per game Arcade A

Part b) Higher entrance fee Arcade B

Part c) Higher total cost for 8 games Arcade B

Step-by-step explanation:

Let

x------> the number of games

Arcade A

we have that the linear equation is

[tex]y=0.75x+2[/tex]

The fee per game is $0.75

The entrance fee is $2

The cost for 8 games is equal to

[tex]y=0.75(8)+2=\$8[/tex]

Arcade B

Find the linear equation

Let

[tex]A(0,8),B(4,10)[/tex]

Find the slope of the line (fee per game)

[tex]m=\frac{10-8}{4-0}=0.50[/tex]

The point A is the y-intercept

The linear equation is

[tex]y=0.50x+8[/tex]

so

The fee per game is $0.50

The entrance fee is $8

The cost for 8 games is equal to

[tex]y=0.50(8)+8=\$12[/tex]

therefore

Part a) Higher fee per game Arcade A

Part b) Higher entrance fee Arcade B

Part c) Higher total cost for 8 games Arcade B

David reads 80 pages every day.

Karen reads 25% more pages every day than David reads.

So, Karen reads [tex]\frac{25}{100}*80= 20[/tex] more pages. She reads a total of 80 + 20 =100 pages.

Rick reads 35% fewer pages per day than Karen. So, Rick reads [tex]\frac{35}{100}*100=35[/tex] less pages than Karen. He reads 100 - 35 =65 pages

So, in total the tree friends read = 80+100+65=245 pages.
