Find the area of a circle with diameter of 10 cm. Let pi = 3.14​

Answers

Answer 1

Answer:

A = 78.5 cm^2

Step-by-step explanation:

The diameter is 10 so the radius is 1/2 of the diameter

r =1/2d = 1/2(10) = 5

The area of a circle is

A = pi r^2

A = 3.14 (5)^2

A = 78.5 cm^2

A sporting goods store receives a shipment of 124 golf bags. The shipment includes two types of bags, full-size and collapsible. The full-size bags cost $38.50 each. The collapsible bags cost $22.50 each. The bill for the shipment was $3430. How much of each type of golf bag should be in the shipment? Show all work and verify your answer (prove that your answer is correct)

Answers

The sporting goods store receives the shipment of 124 golf bags in total.

Let us assume that the number of full-sized bags = X

Then the number of collapsible golf bags = 124 - X

Cost of each full sized bags = $38.50

Cost of each collapsible bags = $22.50

Total cost of the 124 bags received by the sporting goods store = $3430

Then

(38.50)X + (124 - X)22.50 = 3430

(38.50X - 22.50X) + 2790 = 3430

16X = 3430 - 2790

16X = 640

X = 640/16

  = 40

So the number of full-sized golf bags received = 40

Then the number of collapsible golf bags received = 124 - 40

                                                                                = 84

subract 5 5/21 from 13 1/7

Answers

Answer:

The answer is 166/21, or 7 19/21

Step-by-step explanation:

First, you would set up the equation, which is:

13 1/7 - 5 5/21

Next, you would turn them into an improper fraction, which is:

92/7 - 110/21

Then, you would multiply 92/7 by 3/3 because that is the least common multiple for 21 and 7 (which are the denominators). When you are done multiplying, the equation would be:

276/21 - 110/21

Afterwards, you would subtract the numerators and leave the denominators alone, which gives you the answer 166/21. As a mixed number, this would equal 7 19/21.

Answer:

7 19/21

Step-by-step explanation:

13 1/7 - 5 5/21

Get a common denominator

13 1/7*3/3 - 5 5/21

13 3/21 - 5 5/21

We need to borrow 1 from the 13 in the form of 21/21

12 +21/21 + 3/21   - 5 5/21

12 24/21 - 5 5/21

Match each of the following equations according to there slope and y intercept.

Answers

Answer:

using the equation of the line y = mx + b

m= slope

b = y intercept

y= - 1.5x - 4 m = -1.5 b = -4

y = -3x + 4 m = -3 b = 4

y = 3x m = 3 b = 0

y = 1.5x - 7 m = 1.5 b = -7

y = 7 m = 0 b = 7

Hope this helps.

Answer:

y=3x goes with m=3, b=0

y=7 goes with m=0, b=7

y=-3x+4 goes with m=-3, b=4

y=1.5x-7 goes with m=1.5, b=-7

y=-1.5x-4 goes with m=-1.5, b=-4

Step-by-step explanation:

The b represents the y- intercept in a graph (where the line crosses the y axis). The m represents the slope of the line. You can find the slope by taking the rise of the graph and dividing it by the run (rise/run). If you get the numbers in the equation form y=mx+b, then you just take the information they give you out of the equation.

Answers

Answer:

x = 114°

y = 27

Step-by-step explanation:

To get x, we simply subtract 66° from 180°. Because of same-side interior angles, the angle below x is 66°.

To find y, we set the expression equal to 66° because they are the same angle. When we solve for y, we get 27.

Answer:

x= 114,

y= 27

Step-by-step explanation:

x= 180 - 66 = 114

6y - 96 = 66, 6y= 66+96, 6y= 162, y= 162/6, y= 27

The measure of a tangent-tangent angle is half the difference of the
measures of the intercepted arcs.
A. True
B. False​

Answers

Answer:

  True

Step-by-step explanation:

The measure of the angle where secants intersect outside the circle is half the difference of the measures of the intercepted arcs. A pair of tangents is a special case where the intercepted arcs meet each other. The same relation regarding arc and angle measures still applies.

The given statement is true.

The measure of a tangent-tangent angle is one - half the difference of the measures of the intercepted arcs.

What is mean by Angle?

An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.

Now, The diagram is attached below

AB  and BC are the two tangents

By exterior angle theorem

∠3 = ∠2 + ∠4

So   ∠2 = ∠3 - ∠4

Now we find angle 3  and 4, we know when a chord and tangent intersect at a point then the measure of angle is one half of measure of intercepted arc

∠3 = 1/2 arc ADC

∠4 = 1/2 arc AC

∠2 = ∠3 - ∠4

∠2 = 1/2 arc ADC - 1/2 arc AC

∠2 = 1/2 ( arc ADC - arc AC)

Thus, The measure of a tangent-tangent angle is one half the difference of the measures of the intercepted arcs.

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 the Equation:

y= x+ 3

Katherine has two types of iodine in her lab. She has brand 232 iodine, which costs thirty-six cents
per ounce. She also has brand 880 iodine, which costs $2.04 an ounce. How many ounces of each should she use if she wants to make three hundred ninety-three ounces of iodine that cost a total of $255.72?

Answers

Answer:

Number of ounces of iodine 888 brand = 68

Number of ounces of iodine 232 brand = 325

Step-by-step explanation:

Given the following ;

Brand 232:

Cost per ounce = 36cent

Brand 880:

Cost per ounce = $2.04 = 204cent

Assume the following :

Number of ounces of 232 brand = x

Number of ounces of 888 brand = y

Total ounces to be made :

x + y = 393 - - - (1)

Total cost of iodine :

Brand 232 = 36x

Brand 888 = 204y

36x + 204y = 25572 - - - - (2)

From (1)

x = 393 - y - - - - (3)

Substitute (3) into (2)

36(393 - y) + 204y = 25572

14148 - 36y + 204y = 25572

-36y + 204y = 25572 - 14148

168y = 11424

y = 11424 / 168

y = 68

From ; x = 393 - y

y = 68

x = 393 - 68

x = 325

Number of ounces of iodine 888 brand = 68

Number of ounces of iodine 232 brand = 325

Answers

Answer:

x + 2y = -1

Step-by-step explanation:

First, we'll find the slope.

Slope = (2 - (-3)) / (-5 - 5) = 5 / -10 = -1/2

Since we know the slope and a point that belongs to the line, we can write this in point-slope form which will be:

y - 2 = -1/2(x - (-5))      *I used (-5, 2) but it doesn't matter which point you use

y = -1/2(x + 5) + 2

y = -1/2x - 1/2

Standard form:

1/2x + y = -1/2
