Isabella is 10% taller today than she was one year ago. Her current height is 176cm. How tall was she one year ago?

Answer:

Area: 312

Perimeter: 75

Step-by-step explanation:

Area is l·w

20·16=320

two corners aren't filled

320-9-9=318

Add all the sides for perimeter

17+3+3+13+20+13+3+3=75

Answer:

281 m squared

Step-by-step explanation:

What we can first do is find the top length so we can do

17+3+3=23

then we can multiply it by the side length to get the whole rectangle

23*13=299

and we know each of the little areas is 9, and there are two so

9+9=18

and we can subtract that from the whole rectangle

299-18=281

Answer: C=9

The value of c so that the function f ( c ) = 20 is when c = 9

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is given by

f ( x ) = 3x - 7

Now , substituting the value of f ( x ) = 20 , we get

when x = c

f ( c ) = 3c - 7

The value of the equation f ( c ) = 20

Substituting the value in the equation , we get

3c - 7 = 20

On simplifying the equation , we get

Adding 7 on both sides of the equation , we get

3c = 27

Divide by 3 on both sides of the equation , we get

c = 9

Therefore , the value of the variable c = 9

Hence , The value of c so that the function f ( c ) = 20 is when c = 9

Step-by-step explanation:

Answer:

A: 68.25 minutes

B: 12 times

C: 42 mins and you decide this part I actually don't know. But I think it could be reasonable, after 40 times someone should get pretty good at it.

Step-by-step explanation:

a: 72 -0.75*5 = 68.25

b: M=63=72-0.75n

subtract 72 from each side: -9 = -0.75n

divide each side by -0.75: n = 12

so 12 times

c: 72 - 0.75(40) = 42 minutes. Now this could be is reasonable, but we don't know what their desert is. But 40 times is a lot of practice.

Answer:

1/5

Step-by-step explanation:

To find this you would need to multiply the probability of pulling a white marble to the probability of pulling out a green marble.

1)First you would need the probability of pulling out a white marble. There are 10 marbles in total and out of those 2 are white. So the probability of pulling out a white marble would be 2/10. If you simplify that you would get 1/5 for the probability of pulling out a white marble.

2)Next, you would find the probability of pulling out a green marble. Using the same process that we used to find the probability of pulling out a white marble, we would find the answer to be 3/10. All that we did here was green marbles/total marbles. By filling that in we got 3/10 for the probability of pulling out a green marble.

3)Now all that is left is doing probability of pulling a white marble × probability of pulling out a green marble. This would be 1/5 × 3/10. After solving the answer would be 3/15 which we would simplify down to 1/5 as our final answer.

Answer: 36.84

(lmk if this isnt right)

Step-by-step explanation:

To find the perimeter of the rectangle:

3+3+3+3+3+3=18

or

3(6)=18

To find the diameter of the circle:

12-(3+3)

12-6=6

You can combine the 2 half circles to make 1 full circle since they both have the same diameter. Use the circumference formula to solve.

C=πd

Substitute

C=3.14(6)

Multiply

C=18.84

Add the perimeter of the rectangle and the circumference of the circle.

18+18.84=36.84

Given

[tex]8 \div \frac{1}{5} = 40[/tex]

[tex]8 * 5 = 40[/tex]

Required

Explain why both expressions are correct

No dropdown to select from. So, I will provide a general solution.

When a number is divided by a fraction.

Take for instance:

[tex]8 \div \frac{1}{5}[/tex]

The above can be expressed as the product of the number and the inverse of the fraction.

The inverse of 1/5 is 5.

So, we have:

[tex]8 \div \frac{1}{5} = 8 * 5[/tex]

The result of the above expression is:

[tex]8 \div \frac{1}{5} = 8 * 5 = 40[/tex]

Answer:

M1= 35°   M2=30°

Step-by-step explanation:

At the point where the two triangle meet, the north angle is 115°, so the south one will be 115°, because they're alternate angles. This means that to get the other two angles left, you must subtract the two angles that weren't in the triangles on that point = 360° - (115 x 2) = 130°. 130° is the total of the two angles on the point in the two triangles. Then you just subtract the two angles you have for each triangle from 180° to get the last two angles

Answer:

i believe the answer is 162 cubic inches

Step-by-step explanation:

as we know, the rectangles are conjoined but the easiest way to solve this is to separate them (so to speak) with that, let us pretend that we've cut them making two individual rectangles-

so rectangle one's dimensions are-

1, 8,9 (remember that the order the numbers are in is unimportant because the answer will still be the same no matter the order)

and rectangle two's dimensions are-

2,5,9

the formula for the volume of a rectangular prism is v=wlh

now we just need to plug in the information

rectangle one- v=1*8*9=72

rectangle two=2*9*5=90

now let us suppose we've re-conjoined the rectangular prisms-

(meaning we're going to add up the volumes for the total volume of the shape given in your problem)

72+90=162 cubic inches

good luck :)
