Does anyone know how to answer this question I'm having a lot of trouble with it?

Answer:

(4,-2)

Step-by-step explanation:

Answer: C= 25.12

Step-by-step explanation:

Circumference formula: 2nr

The radius of the circle is half of the diameter

If diameter is 8, then the radius is 4

C = 2 x 3.14 x 4

C = 25.12

Answer: C. Two of the side lengths add to a sum that is less than the third side length, so these lengths cannot be used to draw any triangles.

Explanation:

Those two sides in question are 8 and 12. They add to 8+12 = 20, but this sum is less than the third side 24. A triangle cannot be formed.

Try it out yourself. Cut out slips of paper that are 8 units, 12 units, and 24 units respectively. The units could be in inches or cm or mm based on your preference.

Then try to form a triangle with those side lengths. You'll find that it's not possible. If we had the 24 unit side be the horizontal base, so to speak, then we could attach the 8 and 12 unit lengths on either side of this horizontal piece. But then no matter how we rotate those smaller sides, they won't meet up to form the third point for the triangle. The sides are simply too short. Other possible configurations won't work either.

As a rule, the sum of any two sides of a triangle must be larger than the third side. This is the triangle inequality theorem.

That theorem says that the following three inequalities must all be true for a triangle to be possible.

where x,y,z are the sides of the triangle. They are placeholders for positive real numbers.

So because 8+12 > 24 is a false statement, this means that a triangle is not possible for these given side lengths. Therefore, 0 triangles can be formed.

Find 10%:

100% = 2500

1% = 2500 divide 100

= 25

10% = 25 x 10 = 250

Find the 13% vat:

13% = 25 x 13 = 325

Find the total amount he got charged:

325 + 250 = 575

Total amount he had to pay for dinner + charges:

2500 + 575 = 3075

Answer: Rs. 3075

Answer:

0.224

Step-by-step explanation:

Multiply the whole number by the denominator:

22 × 5 = 110

Add the product you got in Step 1 to the numerator:

110 + 2 = 112

Divide the sum from Step 2 by the denominator:

112 ÷ 5 = 22.4

That's it folks! The answer to 22 2/5 in decimal form is displayed below:

22 2/5 = 22.40

[tex]22\frac{2}{5}[/tex] % is equivalent to 0.225 as a decimal.

To convert [tex]22\frac{2}{5}[/tex] % to a decimal, we divide the mixed number by 100.

Convert the mixed number 22 2/5 to an improper fraction:

[tex]22\frac{2}{5}[/tex] = (22 × 5 + 2) / 5

= 112/5

Next, divide the resulting fraction by 100:

112/5 ÷ 100

= 112/5 × 1/100

= 112/500

Simplifying the fraction:

112/500

= 14/62

Divide numerator and denominator by 2:

= 7/31

=0.225

Therefore,  [tex]22\frac{2}{5}[/tex] % is equivalent to 0.225 as a decimal.

We have this as;

As we can see, we have the whole number of inches before it as 2

Now, the small intervals between each of the whole numbers on the ruler is;

Step-by-step explanation:

Answer:

The total amount of paint left is 1.6 gallon of paint remaining

Where she has:

1.5 gallon of orange paint left and 0.1 gallon of black paint left.

Step-by-step explanation:

Step 1

Callie has 2 cans of orange paint with 4.5 gallons in each can.

The total gallons of orange paint that she has is given as:

1 can = 4.5 gallons

2 cans = x gallons

Cross Multiply

x = 4.5 gallons × 2 cans

x = 9 gallons of orange paint.

She also has 9/10 of a gallon of black paint.

Her brother took 0.8 gallon of the black paint

and 3.75 gallons from each of the cans of orange paint.

Since there are 2 cans, the total gallons of orange paint that her brother took = 2 × 3.75 gallons

= 7.5 gallons

Step 2

For orange paint

The amount of orange paint that she has left = 9 gallons - 7.5 gallons

= 1.5 gallons of orange paint left.

For black paint

We are told that: She also has 9/10 of a gallon of black paint.

Converting to decimal

= 0.9 gallon of black paint.

Her brother took 0.8 gallon of the black paint

The total gallon of black paint that she has left =

0.9 gallon - 0.8 gallon

= 0.1 gallon of black paint left.

The total amount of paint Callie has remaining after her brother took the stated amounts is:

1.5 gallon of orange paint + 0.1 gallon of black paint = 1.6 gallon of paint remaining

Hello!

[tex]\large\boxed{4 : 3 \text{ and } 16 : 12}[/tex]

We can go through each answer to verify whether each is equivalent to 8 : 6.

4 : 3 is equivalent to 8 : 6 because reducing the ratio 8 : 6  by a factor of 2 yields 4 : 3.

6 : 8 is not equivalent to 8 : 6 because the ratio is reversed.

16 : 12 is equivalent to 8 : 6 because the ratio is increased by a factor of 2.

10 : 8 is not equivalent to 8 : 6. We can verify this by checking whether each term was scaled equally:

10 ÷ 8 = 1.25

8 ÷ 6 = 1.33. Therefore, they are unequal.

7 : 5 is not equal to 8 : 6 for the same reason.

The only correct choices are:

4 : 3 and 16 : 12.

Answer: The waiting time will be 32 minutes when 240 people in line.

Step-by-step explanation:

Let us assume that the waiting time is directly proportional to the number of people in the queue.

Equation of direct proportion between variables x and y :  [tex]\dfrac{x_1}{y_1}=\dfrac{x_2}{y_2}[/tex]

Put [tex]x_1=20,\ y_1=150,\ y_2=150[/tex]  to find  [tex]x_2[/tex].

[tex]\dfrac{20}{150}=\dfrac{x_2}{240}\\\\\Rightarrow\ x_2=\dfrac{20}{150}\times240\\\\\Rightarrow\ x_2=32[/tex]

Hence, the waiting time will be 32 minutes when 240 people in line.

Answer:

32 minutes

Step-by-step explanation:

According to the scenario, computation of the given data are as follows,

For 150 people, waiting time = 20 minutes

So, for 1 minute waiting time, number of people = 150 ÷ 20

= 7.5 people per minute

So, for 240 people, waiting time = 240 ÷ 7.5

= 32 minutes.

So, the waiting time when 240 people are in line is 32 minutes.

The true statement is that Stephen's factored expression is incorrect

The expression is given as:

[tex]x^2-10x+21[/tex]

Start by expanding the equation

[tex]x^2-10x+21 = x^2-7x - 3x+21[/tex]

Factorize the equation

[tex]x^2-10x+21 = x(x-7) - 3(x-7)[/tex]

Answer:

(-11,-14)

Brainliest is always appreciated :)

Step-by-step explanation:

Left or right affects the x value

left = subtraction of the x value - right = addition to the x value

Up and down affect the y value

down = subtraction of the y value - up = addition to the value

So -8-3=-11 and -9-5=-14. So the answer is (-11,-14)
