Find the area of the triangle. Pls help!

Answers

Answer:

84 mm^2

Step-by-step explanation:

The area of a triangle is

A = 1/2 b *h

The base is 14 and the height is 12

A = 1/2 (14*12)

A = 84 mm ^2

Area of a triangle formula: A = 1/2bh

Solve using the values given in the picture.

A = 1/2(14)(12)

A = 1/2(168)

A = 84

Therefore, the volume of the triangle is 84mm²

Mr. Williams paid $1,250 in cash for a new television set. If he had bought it using the store's payment plan, he would have had to pay a deposit of $350 and 9 monthly installments of $150. How much money did he save by paying in cash?

Answers

Answer:

$450

Step-by-step explanation:

Mr. william's paid $1250 in cash for a new television set. But if he was to use the store's deposit plan, he will have to make some installmental payment after paying an initial deposit.

Initial deposit = $350

Installmental payments of $150 for 9months.

His total payment will be = Initial payment + the total amount of the installmental payment.

$350 + (9 x $150) = $350 + 1350 = $1700

$1700 - $1250 = $450 savings

By paying in cash he will be saving an amount of $450.

P( yellow) = yellow / total = 7/25

Then not replaced

6 yellow, 6 blue, 9 red, and 3 green ribbons in a drawer

Total ribbons = 24 ribbons

what is the slope of the line below? If necessary, enter your answer as a fraction in lowest terms, using the slash as the fraction bar. Do not enter your answer as a decimal number or an equation. (6, 9) (0, -5)​

Answers

Answer:

-7/-3

Step-by-step explanation:

The point (6,9) should be labeled as x1 and y1 and the point (0,-5) should be labeled as x2 and y2, so the slope equation ends up as -5-9 / 0-6, which turns out to be -14 / -6, but when you simplify it, it becomes -7 / -3. :)

The slope of line given below is 7/3.

What is Slope?

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the

change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx where, m is the slope

We have the points as (6, 9) and (0, -5)

So, the slope of line

slope = (-5 - 9)/ (0-6)

slope = -14 / (-6)

slope = 7/3

Thus, the required slope is 7/3.

Denise and Jacqueline are training for a swimming and running race.
• Jacqueline swims for 30 minutes. Then she runs 3.2 miles at a constant
pace. Her total training time is 54 minutes. • Denise swims for 24 minutes.
She runs at a constant pace of 8 minutes per mile. Her goal is to train for at
least 60 minutes. *
Part A: Write an equation or inequality to represent the pace, in minutes per mile, that Jacqueline
runs. Define all variables used. At what pace, in minutes per mile, does Jacqueline run? Show your
work. Respond in the space provided.

Answers

Answer:

Jacqueline runs at 6.25 minutes per mile

Step-by-step explanation:

Here we have that the total training time for Jacqueline = 54 minutes

The time for which Jacqueline swims = 30 minutes

Therefore, the time in which Jacqueline runs = 54 min. - 30 min. = 20 minutes

Therefore the equation for Jacqueline's speed = Distance/Time we have

Jacqueline's pace = 3.2 miles/20 minutes = 0.16 miles/minute

Therefore Jacqueline's pace = 0.16 miles/minute

The equation for Jacqueline's pace in miles/minute is presented as follows

Jacqueline's pace in miles/minute = Time of running/Distance

Jacqueline's pace in miles/minute  = 1/0.16 miles/minute = 6.25 minutes/mile.

He volume V (in cubic feet) of a right cylinder with a height of 5 feet and radius r (in feet) is given by V=5πr2. Solve the formula for r. Then find the radius of the cylinder when the volume is 770 cubic feet. Round your answer to the whole number.

Answers

Answer:

[tex] 770 = 5\pi r^2[/tex]

If we divide both sides by [tex] 5\pi[/tex] we got:

[tex] \frac{770}{5\pi} = r^2 [/tex]

And taking square root we got:

[tex] r = \sqrt{\frac{770}{5\pi}}= 7.001 ft[/tex]

And rounded to the nearest whole number we got 7 ft

Step-by-step explanation:

For this case we know that the hieght of a right cylinder is 5 ft and the volume is given by:

[tex] V = 5 \pi r^2 [/tex]

And we know that the volume [tex] V = 770 ft^3[/tex] and we want to solve for r so we can set up the following equation:

[tex] 770 = 5\pi r^2[/tex]

If we divide both sides by [tex] 5\pi[/tex] we got:

[tex] \frac{770}{5\pi} = r^2 [/tex]

Step-by-step explanation:

Let t= teachers

t * 25% = basic math teachers

t *.25 = 50

Divide each side by .25

.25t/.25 = 50/.25

t =200

Answer:

200

Step-by-step explanation:

The 50 basic math teachers are 25% of all the teachers of the school.

You can use a proportion.

50 is to 25% as x is to 100%

50/25 = x/100

10/5 = x/100

5x = 100 * 10

5x = 1000

x = 200

Meagan knits 1/10 of q scarf in 3/4 of annhour.What fraction of a scaf can megan knit in 1 hour

Answers

Answer:

2/15

Step-by-step explanation:

To solve this problem we just need to use a rule of three, relating the fraction of the scarf knitted and the amount of time.

So we have that:

1/10 of the scarf -> 3/4 hour

x of the scarf -> 1 hour

x * (3/4) = 1/10

x = (1/10) / (3/4)

x = (1/10) * (4/3)

x = 4/30 = 2/15

In one hour, Meagan knit 2/15 of the scarf.

2x^2 + 7x – 9 = 0

Answers

Answer:

x = - 4.5, and x = 1

Step-by-step explanation:

~ Let us solve for x through factorization, but first change the equation to an expression for the simplicity ~

1. First break this expression into groups ⇒ ( 2x^2 - 2x ) + ( 9x - 9 )

2. Now factor 2x from 2x^2 - 2x ⇒ 2x ( x - 1 )

3. Now factor 9 from 9x - 9 ⇒ 9 ( x - 1 )

3. Combine these factored expressions ⇒ 2x ( x - 1 ) + 9 ( x - 1 )

4. Factor out common term x - 1 ⇒ ( 2x + 9 )( x - 1 )

5. Now add 0 to this expression as provided in the start: ( 2x + 9 )( x - 1 ) = 0

6. And now we recieve two answers, calculated through zero product property ⇒ 2x + 9 = 0   and   x - 1 = 0,  ⇒ 2x = - 9   and    x = 1   ⇒

x = - 4.5, and x = 1

The solution of the given expression would be as x = - 4.5, and x = 1.

What is an expression?

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

First we have to break this expression into groups

[tex]( 2x^2 - 2x ) + ( 9x - 9 )[/tex]

Now factor 2x

2x ( x - 1 )

Now factor 9 from 9x

9 ( x - 1 )

Combine these factored expressions as;

2x ( x - 1 ) + 9 ( x - 1 )

Then Factor out common term;

( 2x + 9 )( x - 1 )

Then add 0 to this expression as provided in the start;

( 2x + 9 )( x - 1 ) = 0

By zero product property

2x + 9 = 0   and   x - 1 = 0,  

⇒ 2x = - 9   and    x = 1  

x = - 4.5, and x = 1

The solution of the given expression would be as x = - 4.5, and x = 1.
