MATH HOMEWORK HELP PLEASE I ONLY NEED 22 and 23 DONE

Answer:

x ≈ 41

Step-by-step explanation:

All the angles in a quadrilateral add together to equal 360°

So set up the equation:

a + b + c + d = 360°

Now fill in the values we know:

x + _ + 4x + 2x - 10 + 85 = 360

7x + 75 = 360

Now subtract both sides by 75:

7x + 75 - 75 = 360 - 75

7x = 285

Divide both sides by 7:

7x / 7 = 285 / 7

x = 40.714

Round:

x = 41

Now to check our answer, substitute 41 for x in the equation:

(41) + _ + 4(41) + 2(41) - 10 + 85

(41) + 164 + 82 - 10 + 85 = 362

The answer is close to 360, so we know it is correct

Answer:

x=40 and

+_ is 5

Step-by-step explanation:

Sum of the angles of any quadrilateral is 360.

4x +2x-10 +85 +x+_ = 360 combine like terms

7x + 75 = 360 subtract 75 on each side

7x = 360-75

7x = 285 divide by 7

x = 40.71

Now plug in back into equation x = 40:

4*40+ 2*40 -10 + 85 +40 + _  = 360

missing number is +5

AB = 4.5

Step-by-step explanation:

We can cross multiply the sides in order to find the length of AB. Make sure you don't go diagonal, so you can't do 3/6. You can do 3/4 and 3/x, then match it to the same pattern.

This is the one I chose...

[tex]\frac{4}{3} =\frac{6}{x}[/tex]

Notice how I put them in the same order.

Now we can cross multiply...

[tex]4*x[/tex]

= 4x

[tex]6*3[/tex]

= 18

[tex]4x=18[/tex]

Divide by 4.

x = 4.5

The length of AB is 4.5.

Answer:

42.42in³

Step-by-step explanation:

This problem bothers on the mensuration of solid shapes, a cone

Step one

We know that the volume of a cone is

V= 1/3πr²h

Given data

Diameter d= 6 inches

Radius r= diameter/2= 6/2= 3 inches

Height h = 4.5 inches

Step two

Substituting our given data we have

Volume = 1/3*3.142*3²*4.5

V= 1/3*3.142*9*4.5

V= 127.251/3

V= 42.42in³

Answer:

the square root of the number 25 is 5

Step-by-step explanation:

Answer:Find the domain of y = log(x + 3)

Logarithms can only be taken for positive numbers. So you must have

x + 3 > 0

x > – 3          ✔

So the domain of the function is

D = {x ∈ R:  x > – 3}

or using the interval notation

D = (– 3, +∞)

Answer:

p = 23       and p = -22

Step-by-step explanation:

| 2p -1 | =45

Absolute value equations have 2 solutions, one positive value and one negative

2p-1 = 45    and 2p-1 = -45

Add 1 to all sides

2p-1+1 = 45+1    and 2p-1+1 = -45+1

2p = 46                        2p = -44

Divide by 2

2p/2 = 46/2    and   2p/2  = -44/2

p = 23       and p = -22

Answer:

D

Step-by-step explanation:

a. The median, or line in the middle, is the same for both

b. This is the start to end of the box. For the top one, we have 39-33=6. For the bottom one, we have 36-30=6. These are the same.

c. The range is the highest minus the lowest value. For the top one, this is 41-31=10. For the bottom one, this is 38-28=10. These are the same.

This leaves D as our answer

Answer:

3.33times 10^7 because when it is possible to substract 2.24times10^5 from it

Answer:

Answer: A) 3.33 x 10⁷

Step-by-step explanation:

A is the correct answer because you're adding 7 to the left. Whereas for B, it's only 5 times, and the number is less than 3.33.

3.33 ⇒ 33.3 ⇒ 333 ⇒ 3330 ⇒ 33300 ⇒ 333000 ⇒ 3330000 ⇒ 33300000

2.34 ⇒  23.4 ⇒  234 ⇒  2340 ⇒  23400 ⇒  234000

Step-by-step explanation:

put f(4/3)= 3(4/3)^(2) +2(4/3)-8 =0

so 3x-4 is a factor

similarly, k=35

1. No answer ( may be due to incorrect question)

2. x = -3

y = 4

3. x= 4

y = 2

4.x = -63/40

y= -19/20

Step 1

Multiply equation 1 by the coefficient of x in equation 2

Multiply equation 2 by the coefficient of x I'm equation 1

(after completing this step you will derive equation 3 and 4 )

Step 2

Subtract equation 4 from equation 3

Step 3

Divide both sides of the equation by the coefficient of y

Step 4

substitute your value for y in equation 1 or 2

(after this you will derive the values of x)

Note : This method is for the Elimination of x

Therefore, h = 3, k = - 2

Radius r = 7

Equation of circle in centre radius form is given as:

[tex](x - h)^{2} + {(y - k)}^{2} = {r}^{2} \\ \therefore \: (x - 3)^{2} + { \{y - ( - 2) \}}^{2} = {7}^{2} \\ \red{ \boxed{ \bold{\therefore \: (x - 3)^{2} + (y + 2)^{2} = 49}}}[/tex]

Answer:

42cm²

Step-by-step explanation:

because if the perimeter of the rectangle is 28 then the length is 5, 5 - 11 = 6, the formula for finding the trapezium is to add the 2 parallel sides, half them, then times them with the length so your sum will look like this, 5+9=14, (i knew the other side was 9 as the length of AB is the same as the length of FC, which is the one of the parallel sides of the trapezium) then we do 14÷2=7, finally we times 7 by 6 which is 42cm²
