Answer:

50.24

Step-by-step explanation:

Area = r^2 x 3.14 (pi)

Radius = 8 ÷ 2 = 4

4² = 16

16 x 3.14 = 50.24

Area = 50.24 cm ²

Given:

Total number of students = 10

To find:

How many was can you award first, second, and third place?

Solution:

Total number of students is 10. So, the total possible ways for the first award is 10.

We know that one student can hold only one place. So, after giving the first award, the number of remaining students is 9 and the total possible ways for the second award is 9.

Similarly, the total possible ways for the third award is 8.

Now, the total number of ways to award first, second, and third place is:

[tex]10\times 9\times 8=720[/tex]

Therefore, the total number of ways to award first, second, and third place is 720.

Answer:

x = 11

m(arc)MN = 65

m(arc)NP = 115

m(arc)NQP = 245

Step-by-step explanation:

10x - 45 = 6x - 1

4x = 44

x = 11

m(arc)MN = 10x - 45 = 10(11) - 45 = 110 - 45 = 65

m(arc)NP = 180 - 65 = 115

m(arc)NQP = 360 - 115 = 245

Answer:

Perpendicular

90 degrees

Step-by-step explanation:

When perpendicular lines intersect they form 4 right angles. Since these lines meet at 90-degree angles they must be perpendicular. Also, <ABC is directly across from <EBD, this means they are vertical angles. Vertical angles are congruent, so <EBD measures 90 degrees.

Answer:  

A. 0.25q + 0.10d = 1.00

q + d =7

Step-by-step explanation:  Only logical choice I see.  The others mix up values and units.

The system of equations is

0.25q + 0.10d = 1.00

q + d =7

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. LHS = RHS is a common mathematical formula.

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.

We have,

A jar contains "q" quarters and "d" dimes.

There are 7 coins in the jar and the total value of the coins is $1.00.

As, 2 quarters and 5 dimes

= 2(.25) + 5(.10)

= $.50+ $.50

= $1

Now, according to question,

0.25q + 0.10d = 1

and, 0.10q + 0.10d = 0.7

Solving above equation we get

0.15q = 0.3

q = 2 quarter

Then, d= 7 -q = 7- 2 = 5 quarter

Answer:

13 or B

Step-by-step explanation:

1 pound=16 oz

4 1/4=4.25, 4.25*16=68

68+10=78

78/6=13

6-ounce servings did Bob make be 13 servings.

pound, unit of avoirdupois weight, equal to 16 ounces, 7,000 grains,

Bob made 4 1/4 pounds of fruit salad

10 ounces of pineapple.

as, 1 pound=16 ounces

So, 4 1/4=17/4= 4.25 pounds of fruit salad

Now, 4.25 pounds in ounce = 4.25* 16

= 68 ounces

Total serving = 68+10

= 78

Thus,  6-ounce servings =78/6

The interpretation of the power of this test is that A. If the true proportion of high school students who work a part-time job during the school year is p = 0.747, there is a 0.59 probability that the guidance counselor will find convincing evidence for Ha: p > 0.28.

This refers to the possibility of an event occuring and this is used in statistics and mathematics to make calculations and predictions.

Hence, we can see that the power of the test to reject the null hypothesis if p = 0.747 is 0.59 using a significance level of α = 0.05, the proportion of high school students working is that there is a 0.59 probability that the guidance counselor will find convincing evidence for Ha: p > 0.28.

Answer:

about 7.6

Step-by-step explanation:

I got the measure of the hypotenuse to be about 7.6 because I did the Pythagorean theorem.

a^2+b^2=c^2

The value of a is the first leg (7cm), and the value of b is the second leg (3cm).

So, 7^2+3^2=58. Next, I found the square root of 58. The square root of 58 is 7.615773106. This value rounded to the nearest tenth is 7.6.

In conclusion, the measure of the hypotenuse rounded to the nearest tenth is about 7.6.

[tex]\boxed {\boxed {\sf 6x^2+7x-20}}}[/tex]

Step-by-step explanation:

We are given 2 binomials (meaning they have 2 terms) and asked to express as a trinomial.

To do this, we have to multiply the 2 binomials using the FOIL method. FOIL stands for first, outside, inside, and last. Basically, multiply the first terms from both, then the outside, and so on.

F : First

[tex](\underline{2x}+5)(\underline{3x}-4)[/tex]

2x * 3x= 6x²

O: Outside

[tex](\underline{2x}+5)(3x \underline {-4})[/tex]

2x * -4 = -8x

I: Inside

[tex](2x+\underline5)(\underline{3x}-4)[/tex]

5 *3x=15x

L: Last

[tex](2x+\underline5)(3x\underline{-4})[/tex]

5*-4= -20

Now, put all the products together into one expression.

[tex]6x^2-8x+15x-20[/tex]

However, this is not a trinomial yet. There are like terms that can be combined. Notice how 2 terms both have the variable x. They can be added together.

[tex]6x^2 + (-8x+15x)-20[/tex]

[tex]6x^2+7x-20[/tex]

Now there are 3 terms and we have a trinomial: 6x²+7x-20

Answer:

1: The initial value for option one is not charged

The rate of change for option 1 is $80/hr

Step-by-step explanation:

1. From the pricing options at the car dealership we have;

Option 1

Initial value = Not stated

Fee rate per hour of work = $80

Option 2

Standard fee = $100

Fee rate per hour of work = $400

The initial value for option one is not charged

The rate of change = The increase in payment for each increase in one hour of work = $80/hour

Mathematically, we have;

[tex]The \ rate \ of \ change = \dfrac{\Delta Payment}{\Delta Time} = \dfrac{\$80 - \$0}{1 \, h- 0 \, h} = \$ 80/hr[/tex]

[tex]y=-\frac{3}{4} x-4[/tex]

Step-by-step explanation:

When writing an equation of a line using slope-intercept form: y=mx+b, the slope of the line would take the place of m, and the y-intercept would take the place of b. Just substitute these variables for the slope and y-intercept to find the equation of the line.

lmk if this is incorrect, hope it helps!!

Answer:

y= -3/4x-4

Step-by-step explanation:

This is assuming that you want it in slope-intercept (y=mx+b)

You need to know that

Y= The line

m=Slope

b=y-intercept

Step 1, Replace slope (m)

y= -3/4x+b

Step 2, Replace the y-intercept

y= -3/4x-4

Conclusion to 'what is the equation of the line if its slope is -3/4 and Y-intercept is -4': y= -3/4x-4
