Answer:

What you must do for this case is to extract the relationship of the grapes that were eaten yesterday among the grapes that were eaten today.

To do it, let:

x: number of grapes that Reza ate yesterday

(x / 20) = (100/400).

Clearing x we have:

x = (100/400) * (20) = 5

answer

the number of grapes Reza ate yesterday was 5

Answer:

B. 80.    16 is 20% of 80

Answer:

B. 16 is 20% of 80

Step-by-step explanation:

20×5=100

16×5=80

Answer:

Step-by-step explanation:

Let the red cat be represented by x.

Let the yellow cat be represented by y.

Let the white cat be represented by z.

Which means :

[tex] \tt (1) \: \frac{4}{5} (20x - 5)[/tex]

[tex]\tt = \frac{4}{5} \times 20x - \frac {4 }{5} \times 5[/tex]

[tex] \tt= \frac{80x}{5} - \frac{20}{5} [/tex]

[tex]\tt = 16x - 14[/tex]

Thus, the first statement is correct.

[tex]\tt(2) \: \frac{3}{5} ( \frac{1}{3} z - 10)[/tex]

[tex]\tt = \frac{3}{5} \times \frac{1}{3} z - \frac{3}{5} \times 10[/tex]

[tex]\tt = \frac{3}{15} z- \frac{30}{5} [/tex]

[tex]\tt = \frac{1}{5} z - 6[/tex]

Thus, the second statement is a lie.

[tex]\tt(3) \: \frac{1}{9} ( - 9y - 27x)[/tex]

[tex] \tt= \frac{1}{9} \times - 9y - \frac{1}{9} \times 27x[/tex]

[tex]\tt = \frac{ - 9}{ \: \: 9} y - \frac{27}{9} x[/tex]

[tex]\tt = (- y) - 3x[/tex]

Thus, the third statement is correct.

Therefore, the second one is a lie.

Answer:

Let the money with Miguel be x.

Then :

Money with Kira = x - 9

Money with Charlie = 4x

Total money in their wallet = $105

This can be written in an equation as :

= \tt \: x + x - 9 + 4x = 105=x+x−9+4x=105

= \tt2x + 4x - 9 = 105=2x+4x−9=105

= \tt 6x - 9 = 105=6x−9=105

= \tt6x = 105 + 9=6x=105+9

= \tt6x = 114=6x=114

= \tt x = \frac{114}{6}=x=

6

114

= \tt x = 19=x=19

Which means :

Money with Miguel = $19

Money with Kira :

= 19 - 9

Thus, Kira has $10 in her wallet.

Money with Charlie :

= 4 × 19

= 76

Thus, Charlie has $76 in his wallet.

Therefore,

Money with Kira = $10

Money with Charlie = $76

Money with Miguel = $19

Answer:

118°

Step-by-step explanation:

Two angles are called complementary when their measures add to 90 degrees.

From the question,

Angle A=(2x-10)°

Angle B=(x-2)°

Both Angles are complementary.

Therefore

Step 1

(2x - 10)° + (x - 2)° = 180°

2x + x - 10 - 2 = 180°

3x - 12 = 180°

3x = 180° + 12

3x = 192°

x = 192/3

x = 64°

Step 2

We are to solve for Angle A

(2x-10)°

Angle A = 2(64 ) - 10

Angle A = 128 - 10

Angle A = 118°

The measure of Angle A = 118°

12

Answer:

x= -5

x= 9

Step-by-step explanation:

Answer:

x = - 5, x = 9

Step-by-step explanation:

To find the zeros equate f(x) to zero, that is

(x + 5)(x - 9) = 0

Equate each factor to zero and solve for x

x + 5 = 0 ⇒ x = - 5

x - 9 = 0 ⇒ x = 9

I believe it is C, but i may be wrong.

Question:A cone and a cylinder have the same base area. They also have the same curved surface area. If the height of the cylinder is 3m, then the slant height of the cone (in m) is

Answer:

Given the radius of cylinder and cone are the same because there base areas are same.

Curved surface of cylinder = curved surface area of the cone

∴2πrh=πrl

∴l=2h

Given, height of cylinder =3 cm

Therefore, slant height of cone =6 cm

The volume of the cone is 22π.

Volume of a cylinder = πr²h

55π = πr²(5)

55π = 5πr²

r² = 55π/5π

r² = ✓11

r = 3.3

The volume of the cone will be:

= 1/3πr²h

= 1/3 × π × 3.3² × 6

= 1/3 × 11 × 6 × π

= 22π

Answer:

Step-by-step explanation:

Since this is a test/homework I'll give a hint.

For a linear equation, you have no idea what x and y is, but thats ok! The test itself has already given you 4 options, so you can just input the x/y coordinates, and if they fit, good for you! If they don't, you may need to try again. There are other more complex and faster ways, but they are (a) more complex.

Hope this helps!

The first step that we must take before attempting to solve almost any problem is to determine what the problem statement is asking us to do and what they are giving to us to help finish the problem.  Looking at this question we can see that they have requested for us to solve for x and we were provided with a figure.

After understanding what the problem is asking for us to do we can attempt to solve the problem.  We can see that there are two angles on a straight line and this is known as supplementary angles.  Let us define what supplementary angles are.

In this case we don't have a missing angle but rather a variable that makes up each of the angles.  Using a similar concept we can create an expression with 4x - 6 and 2x and have them combined to equal to 180.  After that we can solve for the unknown which in turn would give us x.

Create an expression

Combine like terms

Add 6 to both sides

Divide both sides by 6

Therefore, after creating an expression and then simplifying it down all the way to just have the value of x equal to something we were able to determine that the unknown variable of x is equal to 31.

When x = 0.8, D. is correct

2.01 > 2.5(0.8)

2.01 > 2 √

Answer:

D.

Step-by-step explanation:

D is the correct answer choice because once you substitute 0.8 with x and multiply, 2.5 and 0.8.

2.5 · 0.8=2

PLS LOOK AT THE PIC I HAVE SENT YOU, HOPE THIS WILL HELP YOU!

Answer:

x = 1/4

Step-by-step explanation:

11 + 22x = 9 + 30x

subtract 22x from both sides

11 = 9 + 8x

subtract 9 from both sides

2 = 8x

divide both sides by 8

2/8 = x

simplify

1/4 = x

Answer:

Assuming you're talking about the angles of a triangle, X would be [tex]34^{.}[/tex]

Step-by-step explanation:

The sum of the angles in a triangle is 180, 180 - 32 - 80 = 68, [tex]\frac{68}{2}[/tex] is 34, so X is equal to [tex]34^{.}[/tex].

Answer:

[tex]\dfrac{1}{64}[/tex]

Step-by-step explanation:

[tex](-32)^{-1.2} = \dfrac{1}{(-32)^{\frac{6}{5}}} = \dfrac{1}{(\sqrt[5]{-32})^6}} = \dfrac{1}{(-2)^{6}} = \dfrac{1}{64}[/tex]

Answer:

(C) 1.75 in

Step-by-step explanation:

It give you a clue in the question that the height increases by the same amount each week. This means that if you add 0.25 you will get a constant answer. What I mean by constant is this :-

0.25 + 0.25 = 0.5 in

I can also do it by multiplying it by 2.

2 × 0.25 = 0.5 in

If you add 0.25 every time or if you multiply 0.25 by the number of weeks you will get your answer same. So,

7 × 0.25 = 1.75 in
