Answer:

1)88 2)44.5

Step-by-step explanation:

i'm not sure about 3 and 4

Answer:

1.) 88cm²

2.) 44.5cm²

3.) 141.37cm²

4.) 44cm²

Step-by-step explanation:

Alrighty, we're just going to do an abridged version, but if you need me to explain it more, I can:

1.) 6 x 8 ÷ 2 = 24

8 x 8 = 64

64 + 24 = 88

1.) 88cm²

2.) 2 + 2 + 3 = 7

7 x 5 ÷ 2 = 17.5

9 x 3 = 27

27 + 17.5 = 44.5

2.) 44.5cm²

3.) 3.14 x 3² = 28.27

3.14 x 6² = 113.1

28.27 + 113.1 = 141.37

3.) 141.37cm²

4.) 3.14 x 4² ÷ 2 = 25.135

4 x 2 = 8

8 x 9 ÷ 2 = 36

8 + 36 = 44

4.) 44cm²

if any of these are wrong, let me know

hope this helps:)

Answer:

y=2x-50

Step-by-step explanation:

[tex]m=\frac{y^2-y^1}{x^2-x^1} = \frac{112-106}{81-78} =\frac{6}{3} =2[/tex]

slope-intercept formula(substitute 81 for x, 112 for y, and 2 for m:

y=mx+b

112=2(81)+b

112=162+b

Then subtract 162 from both sides, and b=-50

Plug in all numbers into original equation

y=mx+b  m=2 b= -50

So u get y=2x-50

Answer:

y = (1/2)x + 25 or y = 0.5x + 25

I used a online calculator that is reliable.

Answer:

First one, 2.88-2.4 since 12% of 24 is 2.88 (For music) and 10% of 24 is 2.4(playing tennis) which is 0.48 hours. Second, Jazz and Opera because 40% of 55 is 22. and together, they add up to 22. PLS BRAINLIEST PLS PLS PLS PLS PLS

Answer:

The representation of Brian's situation in slope intercept form is:

                              y= 15x +70

Step-by-step explanation:

Let x be the number of weeks Brian started his collection.

y be the number of cards Brian has at present.

                         y= 45+25+ 15 x

                   or, y= 15 x +70

which is in the form of,

                              y= mx +c                (slope intercept form)

where,

m= slope

x= x- intercept

c= constant.

Answer:

Step-by-step explanation:

we need to find the surface area of the shapes before adding them together. the triangles are 6*4 and since there are two, we do not need to divide by 2. (normally to find the area of a triangle it is base times height divided by 2)

so the area of the triangles are 24 units. Next we have the outer rectangles. 7*5=35. Since there are 2, we multiply by 2. Last we have the middle rectangle. 7*6=42.

the whole equation would be: 24+70+42= 136

so your answer would be B: 136.

hope this helps :)

Answer:

B. 30

Step-by-step explanation:

What we know: Beyunka has 6 baseballs that she keeps. That is 1/5 of the total that comes in one case.

What we need to know: How many baseballs are in one case?

What we need to do: Divide 6 by 1/5 (or multiply by 5).

6 / (1/5)

Dividing a fraction is the same thing as multiplying by its inverse.

6 * 5

Multiply 6 by 5 to get 30.

30

There are 30 baseballs in one case, so B is our answer.

Answer:

X = 74°

Step-by-step explanation:

90 + 30 = 120 (S + T = 120 )

180 - 120 = 60 (triangles total - S and T's Total = U )

120 - 46 = 74 (The angle TUX is 120 so the answer is 74)

Answer:

38.5sqft

Step-by-step explanation:

If we have the 2 shorter sides of a right triangle, we can compute the area as:

A = ab/2

A = 7ft * 11ft / 2 = 77sqft/2 = 38.5sqft

Answer:

38.5sqft

Step-by-step explanation:

Answer:

Volume is length times width times height. So, you would need to do 9 times 3 (27) times 10 (270). Then, you would divide by 10, because it is scaled down by 1/10, leaving you with 27

Answer:

The price of the soda.

Step-by-step explanation:

The dependent variable is the variable defined to be dependent on another object, typically the independent variable. That means the variable that varies based off of another value is the dependent variable. In this situation, as the number of sodas bought increases, the total price increases. The price varies off of the number of sodas because the increase in sodas causes it to increase. Thus, the price is the dependent variable.

The dependent variable would be the total cost of the sodas.

A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

Given that;

Each soda costs $4.50 at the baseball game.

Here, The cost of the sodas is dependent on the number of sodas purchased, which is the independent variable.

Thus, The dependent variable would be the total cost of the sodas.

Answer: f(x) = 64 * (3/4)^x

Step-by-step explanation: f(x)=ab^x

When x=0 f(x) = 64

64 = ab^0

b^0 =1 so

64 =a

f(x)=64 b^x

When x=1 f(x) = 48

48 = 64 *b

Divide by 64

48/64 =b

6/8 =b

3/4 =b

f(x) = 64 * (3/4)^x
