part a answer is the first triangle

Answer:

The 1st choice

Step-by-step explanation:

(a) the first and second ones are the only triangles with all three acute angles. The 2nd one has more than 1 line of symmetry so the 1st must be the answer.
(b) This one really depends on which side of the triangle is each length. One way to do it is A squared + B squared = C squared. 8 equals c because it is the largest side and 7.5 is A. This would be put out like 56.25 + B = 64. Subtract 56.25 from both sides to get B = 7.75.
OR, if 8 is not the longest side 7.5 squared + 8 squared = C squared which would be 120.25 = C squared. So, you would find the square root of 120.25 which is 10.97.

Ociel has designed a square mural that measures 10 feet on each side. Bill has also designed a square mural, but his measures y feet shorter on each side. How much smaller than Ociel's mural is Bill's mural? Explain.

Answers

Answer:

10²- y²

Step-by-step explanation:

Since the mural is 10 feet on one side we can make the size of Ociel's mural just 10². Of course, the same would go for Bill's mural except we square however long one of his sides is. So just subtract Bill's (y²) from Ociel's (10²).

I think that's right... Sorry if I'm wrong the question was just a bit confusing.

Answer:

m1=51

m2 =39

m3=90

m4=51

m5=17

m6=129

Step-by-step explanation:

m1=51

m2 =39

m3=90

m4=51

m5=17

m6=129

The total of all angles in a triangle is 180.

For angle 1 we are given an angle of 39 and the other of 90 so the angle 1 is 51.

Also we are provided angle 1 plus 2 is 90 so the angle 2 is 90-51 which is 39.

Angle 4 can be found by 180-90- 39which is 51.

If 3 is 180- 39-51= 90

Angle 5 can be found by 180-90-34-39 =17

Angle 6 is 180-35-17=129

Suppose the planned dimensions of a rectangular kitchen have a length-to-width ratio of 3 to 2. The length of the original kitchen is 6z feet. The original kitchen can be made larger by adding four feet to each original dimension. Write a polynomial expression that represents the floor area of the larger kitchen in square feet. Write your answer in standard form.

Answers

Answer:

150 sq. in.

Step-by-step explanation:
Because... Suppose the planned dimensions of a rectangular kitchen have a length-to-width ratio of 3 to 2. The length of the original kitchen is 6z feet. The original kitchen can be made larger by adding four feet to each original dimension. Write a polynomial expression that represents the floor area of the larger kitchen in square feet.

The polynomial expression that represents the floor area of the larger kitchen in square feet is 24z² + 40z + 16

What is Area of Rectangle?

The area of Rectangle is length times of width.

The length-to-width ratio of the original rectangular kitchen is 3 to 2.

Let the width of the original kitchen "w".

Then the length of the original kitchen is length = 3/2×w

We are also told that the length of the original kitchen is 6z feet. We can use this information to solve for the width of the original kitchen:

6z = 3/2×w

w = 4z

So the width of the original kitchen is 4z feet.

To make the kitchen larger, we add four feet to each original dimension. The new length is:

length = 6z + 4 feet

width = 4z + 4 feet

Area = (6z + 4 feet) × (4z + 4 feet)

Multiplying out the terms, we get:

Area = 24z² + 40z + 16 square feet

Therefore, the polynomial expression that represents the floor area of the larger kitchen in square feet is 24z² + 40z + 16

Answer:

x(angle A)=18.9 Angle B=94.5 Angle C=66.6

Step-by-step explanation:

Angle A+ angle B+ Angle C= 180

(x)+(5x)+(4x-9)= 180

add the x components: x+5x+4x= 10x

10x-9 =180

add 9 to each side to balance the equation

10x=189

Divide each side by 10 to get x

10x/10=x 189/10= 18.9

x=18.9

Put x back into the equations

B=5x B=5(18.9) B=94.5

C=4x-9 C=4(18.9)-9

C=66.6

Answer:

We first solve for x, then plug that value into all angle measures.

As selected in the first part,

m∠A + m∠B + m∠C = 180°,

We use this formula to solve for x.

Replace those angle variables with its actual equations, knowing that:

Angle A = x °Angle B = 5x°Angle C = 4x - 9°

So, set up the equation:

m∠A + m∠B + m∠C = 180°,

x + (5x) + (4x - 9) = 180°

Solve for x;

x + (5x) + (4x - 9) = 180°

Group and combine like terms;

(5x + x + 4x) + (-9) = 180°

10x - 9 = 180°

Get rid of constants;

+9 +9

10x = 189°

Get rid of co-efficient;

÷10 ÷10

x = 18.9°, x is equal to 18.9°.

Now, plug the value of x into angle 'A':-

x °

(18.9) °

∠A = 18.9°.

Then, plug the value of x into angle 'B':-

5x°

5(18.9) °

94.5°

∠B = 94.5°.

Finally, plug the value of x into angle 'C':-

4x - 9°

4(18.9) - 9°

75.6 - 9°

66.6°

∠C = 66.6°.

A store is giving out cards labeled 1 through 10 when customers enter the store. If the card is an even number, you get a 15% discount on your purchase that day. If the card is an odd number greater than 6, you get a 30% discount. Otherwise, you get a 20% discount. The table shows the results of 400 customers. What is the relative frequency for each discount? If the manager of the store wants approximately half of the customers to receive the 20% discount, does this seem like an appropriate method? Explain.

Answers

Answer:

Step-by-step explanation:

It is not an appropriate method because if you add all of the people that got 1, 3, and 5 together to get all the people that got the 20% discount, you get 140/400 people, and in order for it to be half there would have to be, or close enough to, a total of 200/400 people.

15% discount = 185/400 or 46.25%

20% discount = 140/400 or 35%

30% discount = 75/400 or 18.75%

Equation:
Answer: p =

Answers

Answer:

16 players can be brought to the tournament. The equation is written within my step-by-step explanation.

Step-by-step explanation:

Variable p = number of players

Set up an equation:

974.50 + 60.75p = 1946.50

Isolate variable p:

60.75p = 972

Divide:

p = 16

Check your work:

974.50 + 60.75(16) = 1946.50

974.50 + 972 = 1946.50

1946.50 = 1946.50
