Sam has 2 dollars less than Alex. How do we write this as an equation?

Answer:

x>15.5

Step-by-step explanation:

x - 10.2 > 5.3

Add 10.2 to both sides

x-10.2+10.2>5.3+10.2

Simplify getting the answer of

x>15.5

Answer:

1: 31.5. 2: 5. 3: 4.6 4: 45

Answer:

Total cost= $100

Step-by-step explanation:

Giving the following information:

Each box has 10 brooms. Each broom is sold for $ 15

The charity earns $ 50 profit for each box of brooms.

First, we need to calculate the total revenue per box:

Total revenue per box= 10*15= $150

Now, the total cost:

Total cost= total revenue - total income

Total cost= 150 - 50

Total cost= $100

Answer:

29.42 units

Step-by-step explanation:

1) Find the perimeter around the semi-circle

To do this, we find the circumference of the circle using the given diameter:

[tex]C=\pi d[/tex] where d is the diameter

Plug in 6 as the diameter

[tex]C=\pi (6)\\C=6\pi[/tex]

Divide the circumference by 2

[tex]\frac{6\pi }{2} \\= 3\pi[/tex]

Therefore, the perimeter around the semi-circle is 3π units.

2) Find the perimeter around the rest of the shape

Although it's impossible to determine the lengths of the varied sides on the right side of the shape, we know that all of those vertical sides facing the right add up to 6. We also know that all of those horizontal sides facing up add up to 7. Please refer to the attached images.

Therefore, we add the following:

7+6+7

= 20

Therefore, the perimeter around that area of the shape is 20 units.

3) Add the perimeter around the semi-circle and the perimeter around the rest of the shape

[tex]20+3\pi \\= 20+9.42\\= 29.42[/tex]

Therefore, the perimeter of the shape is approximately 29.42 units.

I hope this helps!

Answer/Step-by-step explanation:

Problem 1:

E is the centroid of the triangle.

Centroid theorem states that the centroid is ⅔ of the distance of each vertex to the midpoint of the side opposite each vertex.

This implies that:

AE = ⅔(AD)

AE = 21

Therefore:

21 = ⅔(AD)

3*21 = 2(AD)

(3*21)/2 = AD

31.5 = AD

AD = 31.5

Problem 2: Apply the centroid theorem. Thus:

DE = ⅓(AD)

DE = 12

Therefore,

12 = ⅓(AD)

12*3 = AD

36 = AD

AD = 36

Answer: 22/25

Step-by-step explanation:

54x+6x-30=7(x+2)+3x

60x-30=7(x+2)+3x

60x-30=7x+14+3x

60x-30=10x+14

60x-10x-30=14

60x-10x=14+30

50x=14+30

50x=44

x=22/25

Answer:

The Notation for each event Not been independent = P( HT ) or P( TH )

Step-by-step explanation:

when A fair coin flipped ; P( H ) = 0.5 and P( T ) = 0.5

Hence when it is flipped twice the possible outcome = 4

= HH , HT , TT, TH

Since Notation for conditional probability = P ( HH )  this shows that each flip is independent

The Notation for each event Not been independent = P( HT ) or P( TH )

Answer: P(H on 2nd flip|H on 1st flip)=P(H on 2nd flip)

Answer:

65

Step-by-step explanation:

All the angles in a right triangle add up to 180

plug in what we know and we get

90+25+x=180

115+x=180

x=65

-2

Divide each term (-4x = 8 by -4)

Cancel the common factor of -4

x = 8/-4

THEN DIVIDE

Answer:

D

Step-by-step explanation:

The intersection of the graphs is at (-3,4).

Answer:

(-3,4)

Step-by-step explanation:

we have to find the point in common of the two lines, that is where they intercept.

when we write a point, we have to sign first the coordinate of the x, and then the coordinate of the y.

So the answer is : (-3,4)

Answer:

4x+8x = 180 degrees, so x=15

Step-by-step explanation:

Answer:

sum of 4x and 8x is 180°

( straight line )

Answer: 8

Step-by-step explanation: It's just GCF.  The greatest common factor (GCF) of 8 and 16 is 8 (8 and 16 are both divisible by 8 but not by anything greater) which brings us to our answer.

Answer:

7,000 - 2,386 = 4,614

Answer:

The answer is D

Step-by-step explanation:

Don't worry, no links here :)

Answer:

113°

Step-by-step explanation:

Measure of central angle is equal to the measure of its corresponding arc.

Here, x is the measure of the central angle and 113° is the measure of its corresponding arc.

Therefore, x = 113°

Answer:

D. Neither Ryan nor Addy

Step-by-step explanation:

Square:

A square is a quadrilateral that has equal sides and all angles equal to 90 degrees.

Rectangle:

A rectangles is a quadrilateral that has equal or unequal  sides and all angles equal to 90 degrees. All rectangles are not squares.

Rhombus:

A rhombus is a quadrilateral that has equal sides and all angles may or may not be  equal to 90 degrees. All squares are rhombus. But all rhombus are not squares.

As both Ryan and Addy have missed out one property of square therefore both of them are incorrect.
