Can someone help me with 17 20 and especially 21
Only reply if your seriously trying to help me it would be really appreciate

Answer:

x = 4

Step-by-step explanation:

5x-4=16

Add 4 to both sides of the equation.

5x = 20

Divide both sides by 5.

x = 4

Answer:

x=4

Step-by-step explanation:

You first add 4 to both sides and get 5x=20. Then you divide both sides by 5 to isolate the x and get x=4.

Hope this helped :)

Answer:

x = {-8 - √10, -8 + √10}     exact answer

x = {-11.16, -4.84}     decimal approximation

Step-by-step explanation:

2(x + 8)²+ 9 = 29

Subtract 9 from both sides

2(x + 8)² = 20

Divide both sides by 2

(x + 8)² = 10

Take the square root of both sides

x + 8 = ±√10

Subtract 8 from both sides

x = -8 ± √10

x = {-8 - √10, -8 + √10}     exact answer

x = {-11.16, -4.84}     decimal approximation

Answer:

∠C≅∠J

Step-by-step explanation:

Two triangles will be congruent by SAS information required ∠C≅∠J.

The missing information that we need to establish a side angle side congruence is that ∠C≅∠J.

The congruence of a triangle can be established on three basis;

Now we know from the figure that the sides /CL/ = /JK/. It then follows that the missing information that we need to establish a side angle side congruence is that ∠C≅∠J.

Answer:

4: No

5: A

Step-by-step explanation:

4: The mapping does now represent a function. In a function each x value can only have 1 corresponding y value ( meaning that the x values can not repeat.) In the mapping the x value 3 corresponds with 2 y values therefore the mapping is not a function.

Formula for volume of a cylinder = [tex]V=\pi r^2h[/tex]

Where r = radius and h = height

The cylinder shown has a given diameter of 22ft and a given height of 10ft

In order to use the formula we must convert the diameter to radius.

To do this we divide the diameter by 2 ( this is because the radius is equal to half the diameter )

so radius = 22/2 = 11

Now we plug in the dimensions into the formula

[tex]V=\pi 11^210\\11^2=121\\121*10=1210\\1210\pi[/tex]

Remember, it says " Leave your answer in terms of pi," therefore we do not apply pi and leave it as 1210π

We can conclude that the answer is A

Answer:

See solution below

Step-by-step explanation:

The centre of the circle will be the midpoint of both coordinate

Given the coordinates P(-7, -10) and Q = (3,2)

X = x1+x2/2

X = -7+3/2

X = -4/2

X = -2

Y = y1+y2/2

Y = -10+2/2

Y = -8/2

Y = -4

Hence the centre is at (-2, -4)

The distance between the coordinates will be the diamter

PQ =√(3+7)² + (2+10)²

PQ =√(10)² + (12)²

PQ = √100+144

PQ =√244

radius = √244/2

Get the equation

(x-a)² + (y-b)² = r²

(x -(-2))² + (y-(-4))² = (√244/2)²

(x +2)² + (y+4)² = (244/4)

(x +2)² + (y+4)² = 61

This gives the required equation

SA ==736^2

Without unit = 736^2

Step-by-step explanation:

Start with base of a triangle face

Base = 12 Height = 8

1/2 x 12 x 8 =  48  cm^2      one side face surface area

48 x 2 = 96 cm^2               two side face surface area bold

----

Sides

10 x 20 = 200 cm^2            one side face surface area

200 x 2 = 400 cm^2           two side face surface area bold

-----

base 20 x 12 = 240 cm^2    single base. bold

Add up those values in bold =  240 + 400 + 96 =736 cm^2

Answer:

50% is water

Step-by-step explanation:

1. 80% is water and 20% is from other material

2. Lets say a fruit has 100g, to make it easier to understand

2. if the fruit loses 75% of its water, it will lose 75% of 80%, which is 60% of the total weight or 60g lost. The fruit is now 40g

3. If 20% was other material (20g), now other material is 50% (the same 20g)

4. Water is now only 20g, which is 50% of the total weight

Answer:

50% is water I think I am really sorry I I is wrong

Answer:

35 degrees

Step-by-step explanation:

An isosceles triangle has two opposite sides. If the two angles are equal , it means the triangle is an isosceles. Because 90 degrees is greater than 45 degrees, the two sides with the same length, would have a smaller length than the third side

sum of angles in a triangle = 180

180 - 110 = 70

since 2 angles would be equal

70 / 2 = 35

Answer:

12

Step-by-step explanation:

Please write this function as P(x) = x^3 + 7x^2 + 4x + 0.  This third order function has four coefficients.  We set up synthetic division with -2 as the divisor:

-2   /   1    7    4    0

              -2   -10  12

     ----------------------

        1      5     -6  12

The remainder is 12.  Accordng to the Remainder Theorem, the value of P(x) at x = -2 is 12.

Answer: depends on which probability you want (tell me and I’ll edit)

Step-by-step explanation:

10 blue

8 red

6 white

24 total

Pick a red marble: 8/24 or 1/3

Pick a blue marble: 10/24 or 5/12

Pick red or white: 14/24 or 7/12

do you want to know the probability of doing all that (pick red, put back, pick blue, put back, then pick red or white)? Or just the probability of each outcome?

Answer:

A. 30

B. 6

Step-by-step explanation:

We'll use P for Penny's age and B for Benny's age. When Penny is 24, Benny will be 1.25 her age. Thus:

B = 1.25 * 24

(benny is 25% older than her)

So Benny's age then will be 1.25 * 24 = 30.

When Benny is 30, Penny will be 24. This means that he is older than her by 6 years. Think about it for a second: Benny will always be 6 years older than her. You can write that as:

B = P + 6

If Benny is 12 years old now,

12 = P + 6

Subtract 6 from both sides and you get

6 = P

or P = 6

Penny is 6 years old when Benny is 12.
