Find the area of the triangle that has a base of 16 yd and a height of 9 yd

Answers

Answer 1
72 because it would be 9 times 16 divided by 2
72=(9x16)/2
Answer 2
The area of triangle can be found using the formula 1/2bh

b is the base and h is height.

1/2(16)(9)
1/2(144)
72.

The area is 72 yd²

Answer:
Area of wall = [tex] 94 \frac{47}{48} [/tex] ft

Explanation:
First, we know that:
1 in = 1/12 ft
Therefore, the dimensions of the wall would be as follows:
H = 7 ft 10 in = [tex] 7 \frac{10}{12} [/tex] ft
B1 = 10 ft 2 in = [tex]10 \frac{2}{12} [/tex] ft
B2 = 14 ft 1 in = [tex]14 \frac{1}{12} [/tex] ft

For the trapezium, area can be calculated using the following the following formula:
Area of trapezium = Average base * height = [tex] \frac{B1 + B2}{2} [/tex] * height

Substitute with the given to get the area as follows:
Area of wall = ([[tex]10 \frac{2}{12} [/tex] + [tex]14 \frac{1}{12} [/tex]] / 2) * [tex] 7 \frac{10}{12} [/tex]
Area of wall = [tex] 94 \frac{47}{48} [/tex] ft

Cylinders A and B are congruent. Cylinder A has a volume of 27π cm3 and a height of 3 cm. What is the area of the base of cylinder B?

Answers

To find this answer you would use the formula for finding the volume of a cylinder. Because both of these cylinders are congruent, the area of the base for cylinder A I would also be the same area for cylinder B. V=pi x r^2 x h. When we substitute in what we know this is the new equation: 27 x pi = pi x r^2 x 3. Divide both sides by three and pi. This gives us 9 = r^2. Take the square roots of both sides to find the radius. The answer would be 3. Now use the formula for area of a circle to find the area of the base of cylinder B. A= pi x r^2. So the area would be 9 x pi.

Answer:

barry has an ice tray that makes ice cubes shaped like a cone with a diameter of 2 cm and height of 2 cm to the nearest cubic centimeter what is the volume of an ice cube from barry's tray 2cm2 8cm3 25 cm3 101 cm2

Answers

we know that
the volume of a cone=(1/3)*pi*r²*h
where
r is the radius
h is the height

in this problem
diameter=2 cm
so
r=diameter/2-----> r=2/2-----> r=1 cm
h=2 cm
volume of a cone=(1/3)*pi*1²*2------> 2.09 cm³------> 2 cm³

the answer is
2 cm³
Answer
2 cm²

Explanation 
The volume of a cone is found by the formula;
Volume =1/3 πr² h
Where π=3.142
r=2/2=1 cm
h=2 cm
Volume = 1/3×3.142×1²×2
2.09466667
To the nearest whole number the answer is 2 cm².

Sarah needs to buy 3 identical shirts to wear. She had $15 gift certificate. Including using the gift certificate, she can spend no more than $80. Which inequality can be used to determine the possible costs for a shirt ?

Answers

Let the cost of a shirt be s.

Three shirts = 3s.

3s + 15 ≤ 80 (Answer F)
Final answer:

The inequality that can be used to determine the possible costs for a shirt is 3x ≤ 65, where x represents the cost of each shirt. Therefore, the possible costs for a shirt must be less than or equal to $21.67.

Explanation:

To determine the possible costs for a shirt, we can use the inequality 3x ≤ 80 - 15,

where x represents the cost of each shirt. The left side of the inequality, 3x, represents the total cost of the 3 shirts. The right side of the inequality, 80 - 15,

represents the amount Sarah has left to spend after using the gift certificate.

Simplifying the inequality, we get 3x ≤ 65.

To find the maximum cost for each shirt, we divide both sides of the inequality by 3, giving us x ≤ 21.67.

Therefore, the possible costs for a shirt must be less than or equal to $21.67.

Tameron is driving 540
miles to college.
He drives at a rate of 45
miles per hour.

How many hours will it take him to get 34
of the way there?

Answers

Do 540 ÷ 45 as you're first step. Then multiply that by 3/4.

540÷4= 12.

12 × 3/4 = 9.                       Awnser: 9

Answer:

[tex]\Delta t=9\: hours[/tex]

Step-by-step explanation:

1) If Tameron is driving 540 miles at a rate of 45 mph, then he may take 12 hours to  make that trip. We'll use the formula below, that relates the rate for average speed is equal to the variation of space over the variation of time.

[tex]V_{m}=\frac{\Delta s}{\Delta t}\Rightarrow 45=\frac{540}{\Delta t}\Rightarrow \Delta t=\frac{540}{45}\Rightarrow 45\Delta t=540\:\Rightarrow \Delta t=\frac{540}{45}\Rightarrow \Delta t=12[/tex]

2) Although if he's already done 1/4 of the way , i.e. 135 miles then he's left with [tex]\frac{3}{4}[/tex]of the track to go.

Assuming He'll keep the speed rate,

[tex]\Delta t=\frac{540*\frac{3}{4}}{45}\Rightarrow \Delta t=9\: hours[/tex]

The constant of proportionality in terms of the cost per text is the coefficient of [tex]t[/tex] in the equation [tex]b=0.25t[/tex]. Since the coefficient of [tex]t[/tex] is 0.25, the constant of proportionality in terms of the cost per text is 0.25.
Proportionality constants are usually expressed as fractions, so lets convert 0.25 to a fraction. To do that we are going to add the denominator 1 to our decimal, and then we will multiply both numerator and denominator by ten for every number after the decimal point:
[tex] \frac{0.25}{1} [/tex]
[tex] \frac{0.25}{1} . \frac{100}{100} = \frac{75}{100} [/tex]
Finally, we can simplify our fraction:
[tex] \frac{25}{100} = \frac{1}{4} [/tex]

We can conclude that the constant of proportionality in text of the cost per text is 1/4

Hello there!

If this would be the case, we would then simplify this into a fraction and make it look like 3/10.

We do this because 30% is .3 of 1, like we already considered, and because of this, 10=1, and 3=30%.

What is a fraction?

In Mathematics and Geometry, a fraction simply refers to a numerical quantity (numeral) which is not expressed as a whole number. This ultimately implies that, a fraction is simply a part of a whole number.

In this exercise and scenario, we would convert the given decimal number 0.65 into a fraction by converting it into a percentage as follows;

0.65 = 65/100

By dividing both sides by 5, we have:

Fraction: 65/100 = 13/20.

Rewrite the following equation in slope-intercept form. 17x + 4y = -14 Write your answer using integers, proper fractions, and improper fractions in simplest form.

Answers

Answer:
y = [tex] \frac{-17}{4} x[/tex] - [tex] \frac{7}{2} [/tex]

Explanation:
The slope-intercept form of an equation has the following formula:
y = mx + c
where:
m is the slope
c is the y-intercept

The given is:
17x + 4y = -14

To put this in slope-intercept form,we will need to isolate the y as follows:
17x + 4y = -14
4y = -17x - 14
y = (-17/4)x - (14/4)
y = [tex] \frac{-17}{4} x[/tex] - [tex] \frac{7}{2} [/tex]
where:
m is the slope = -17/4
c is the y-intercept = -7/2

Hope this helps :)

17x+4y = -14
Y= 0
17x = -14
X=-14/17

X=0
4y= -14
Y= -14/4

how long will it take for the pool to completely fill with water? (explain why so i understand) it’s a 120 gallon pool

Answers

First, you find out how much can be filled in 1 minute. Then you divide that into 120 to get your answer. 

To find out how much can be filled in 1 minute, take the time and divide it into the volume. We'll use the second row (2 minutes and 8 gallons.)

8/2=4. So it takes 1 minute to fill 4 gallons. Now, you just divide 4 into 120. 

120/4=30

It takes 30 minutes to fill the pool up to 120 gallons. 

It would take 30 min to fill up the pool

Hello there! I can help you! The formula for compound interest is P(1 + r)^t, where P= principal (initial amount), r = interest rate (in decimal form), and t = time (in years). Let's do this step by step. First off, we add the rate into 1. 4% is the interest rate (0.04 in decimal form). 1 + 0.04 is 1.04. Now, what we will do is raise that number to the 2nd power, because the time that elapses is 2 years. 1.04² is 1.0816. That's that. Now, multiply 7,500 to find the total amount of money. 1.0816 * 7,500 is 8,112. There. Toby's savings account balance in 2 years is £8,112.

Note: To solve for compound interest questions like it, add 1 to the percentage rate in decimal form, raise that number to a power based on the number of years (for example, raise the number to the 7th power if we are looking for the balance after 7 years), and then multiply that number by the starting amount. After you raise the number by a power, there may be a lot of numbers behind it. Whatever you do, DO NOT delete the number. Keep it there and multiply it by the principal.
