Given that a = 15 cm and b = 8 cm, work out x

Answers

Answer 1

Answer:

the value of x is 17 cm

Step-by-step explanation:

The computation of x is shown below:

Here we applied the pythagoreans theorem

x^2 = a^2 + b^2

x^2 = 15^2 + 8^2

X^2 = 225 + 64

x^2 = 289

x = sqrt(289)

= 17

Hence, the value of x is 17 cm

Given That A = 15 Cm And B = 8 Cm, Work Out X

m∠R=140 and m∠S=100. Find the m∠T. The diagram is not on the scale.

Answers

Answer:

m<T = 20°

Step-by-step explanation:

m<R = 140°

m<S = 100°

The figure given is a kite. The angles formed where two unequal sides meet are always congruent to each other. This means:

m<S = m<U = 100°

Sum of all interior angles of a quadrilateral = 360°

Therefore:

m<T = 360° - (m<S + m<U + m<R)

m<T = 360° - (100° + 100° + 140°) (substitution)

m<T = 20°

1. Greatest common factor (GCF) would be 15, so the answer would be C, 15(x+2)

2. You are able to distribute -5, and you get -5x when it goes into x, and you get positive 10 because it is a negative times a negative. So the answer would be B, -5x + 10

3. On this type of problem, when there is a negative in the middle, you MUST turn it positive. This means you distribute the negative, and everything on the right of the minus sign changes to negative or positive. So it would change to -
(8x-6)+(x-4)
When you add, you get 9x-10, which is C.

4. Simply just add these two, which is what we got to on the last problem, and you get 20x-6, which is choice A.

5. For this, you substitute the numbers in the equation. So it would be -
2(5)-4(-1)
This would equal 14, which is A.

6. You substitute 4 for x, so it would be -
4^2 + 5
4 • 4 + 5
16 + 5
21, Choice B

7. When you combine like terms here, the 3y’s cancel out because they equal each other, so the answer would just be 19, which is A.

The answers for the given Expression are;

1) 15(x+2)

2) -5x + 10

3) 9x - 10

4) 20x - 6

5) 14

6) 21

7) 19

What is an Expression?

Numbers, symbols and operators (such as and times) grouped together that show the value of something.

Given are the Expressions to solve;

1) 15x + 30

GCF for this Expression is 15 therefore

15x + 30 = 15(x+2)

2) -5(x - 2) = -5 + 10

3) (8x - 6) - (-x + 4) = 8x - 6 + x - 4 = 9x - 10

4) (11x - 2) + (9x - 4) = 20x - 6

5) 2x - 4y when x = 5 and y = -1

2x - 4y = 2*5 - 4*(-1) = 14

6) x² + 5 when x = 4

4² +5 = 16 + 5 = 21

7) -3y + 12 + 3y + 7 = 19

Hence, The Answers are :

1) 15(x+2)

2) -5x + 10

3) 9x - 10

4) 20x - 6

5) 14

6) 21

7) 19

Answers

Answer: 36,960 ft

Step-by-step explanation:

Each lap around the track was a mile in distance.

Petrov therefore ran a total of 7 miles.

A mile is 5,280 feet.

If Petrov ran 7 miles in total, this distance in feet is:

= 7 * 5,280

= 36,960 ft

Noralie has a home-based business putting on children’s parties. She charges $45 to design the party and then $5.50 per child. Write a function rule that relates the total cost of the party to the number of children n.

f(n) = 5.5 – 55n

f(n) = 5.5n – 55

f(n) = 5.5 + 45n

f(n) = 45 + 5.5n

Answer:

The answer would be C because n is the number of children and it costs $5.50 per child plus an extra design fee of $45

Step-by-step explanation:

Design = $45

rate per child = $5.50

number of children, x

total cost, f(x) = $5.5x + $45
