Answer 1

Answer:

x = 42.5

Step-by-step explanation:

A triangle formed inside of a circle using the diameter as one of its side lengths is a right triangle

The right angle would be the angle opposite of the diameter (∠C)

A right angle has a measure of 90°

That being said we use this equation to solve for x

90 = 2x + 5

step 1 subtract 5 from each side

90 - 5 = 85

5 - 5 cancels out

now we have 85 = 2x

step 2 divide each side by 2

85/2=42.5

2x/2=x

we're left with x = 42.5

A teacher buys 6.25 ounces of a compound for an experiment. The compound costs $4.12 per ounce. The teacher pays with a $50 bill. How much change does the teacher receive?

Answers

Answer:

$24.25

Step-by-step explanation:

Given data

We are told that 1 ounce cost $4.12

Hence 6.25 ounces will cost x

cross multiply

x= 6.25*4.12

x=$25.75

This means that the cost of the 6.25 ounces is $25.75

If the teacher pays with a $50 bill, then her change is

=50-25.75

=$24.25

the drawing below shows the dimensions of skims kite what is the area of Kim's kite

Answers

Answer:

48 square inches

Step-by-step explanation:

Given

See attachment for kite

Required

The area of the kite

The given kite has a triangular shape.

So, the area is:

[tex]Area = 0.5 * base * height[/tex]

From the attachment

[tex]base = 12in[/tex]

[tex]height = 8in[/tex]

So:

[tex]Area = 0.5 * 12in* 8in[/tex]

[tex]Area = 48in^2[/tex]

Answers

Answer:

Step-by-step explanation:

(a+b)/2 x h

42 = (8+4)/2 x h

42 = 6h

h = 7

Answer:

height = 6.92820323028km (you can round if you want to)

Step-by-step explanation:

8km - 4km = 4km (this is for one of the side lengths of the traingle)

a² + b² = c²

4² + b² = 8² (b will be used to represent the height)

16 + b² = 64

b² = 48

b = 6.92820323028km

Answers

Answer:

angle c = 107°

angle b = 107°

angle a = 73°

Step-by-step explanation:

Given:

Two line XY and WZ intersect each other and make four angle [a, b, c, d]

Given that Angle d = 73°

Find:

angle a

angle b

angle c

Computation:

We know that angle c and angle d situated on same line XY

So,

angle c + angle d = 180°

angle c + 73° = 180°

angle c = 107°

We know that angle b and angle d situated on same line WZ

So,

angle b + angle d = 180°

angle b + 73° = 180°

angle b = 107°

angle a and angle d are vertical opposite angle

So,

angle a = angle d

angle a = 73°

Which statement about gravity is true?
A. Gravity pulls all objects together, big or small
B. Gravity decreases as mass decreases
C. Gravity decreases as distance increases
D. Gravity pulls only very large objects together

Please help, If I don't get at least a B my parents will kill me.

Answers

Answer:

D is false

A is true

B is true

C is true

Step-by-step explanation:

Answer:

I this a multiple choice answer? I found that A B and C are true.

I know this because the article Newtons laws of Universal Gravitation states that "Since gravitational force is inversely proportional to the square of the separation distance between the two interacting objects, more separation distance will result in weaker gravitational forces. So as two objects are separated from each other, the force of gravitational attraction between them also decreases." This makes C the best answer

In the coordinate plane below, quadrilateral PQRS is reflected over the x-axis. Which segment is segment QR congruent to?

Answers

Answer:

Q'R'

Step-by-step explanation:

Given

Quadrilateral PQRS

Reflected over x-axis

Required

Congruent side to QR

This question has a missing attachment, but can still be solved without the attachment.

When a shape is reflected, the sides and the angles of the shape remain unchanged.

This means that when PQRS is reflected to give P'Q'R'S, the following sides will be congruent.

[tex]PQ = P'Q'[/tex]

[tex]QR = Q'R'[/tex]

[tex]RS = R'S'[/tex]

[tex]SP = S'P'[/tex]

Hence, QR will be congruent to Q'R'

is 4x+5 eqvalent to 4(x+5)

Answers

Answer:

Step-by-step explanation:

4x+5 is not equivalent to 4(x+5) because when you solve for 4(x+5) using distributive property it equals 4x+20 which is not the same as 4x+5.

Answer:

Step-by-step explanation:

No, 4x+5 does not equal 4(x+5), because the operations are different for each expression.

4x+5 is an addition expression and 4(x+5) operation is multiplication.

You must using the distributive property to find the product: 4(x+5) = 4(x) + 4(5) = 4x +20

Therefore, 4x+5 is not equivalent to 4(x+5).

4x+5 is not equivalent to 4x+20.
