Step-by-step explanation:

Point C is located 5 units from points M.

Point C : (-1, 6)

Point M : (-6, 6)

Distance between two points:

[tex]d=\sqrt{(x_2-x_1)^2 +(y_2-y_1)^2 }[/tex]

[tex]d=\sqrt{(-6-(-1))^2 +(6-6)^2 }[/tex]

[tex]d=\sqrt{(-5)^2 +(0)^2 }[/tex]

First solve for x, then find ∡RQW. ∡WQP=139+x, ∡RQW=31+x & ∡RQP=152°

Answers

Answer:

[tex]x = -9[/tex]

[tex]RQW = 22[/tex]

Step-by-step explanation:

Given

[tex]WQP = 139 + x[/tex]

[tex]RQW = 31 + x[/tex]

[tex]RQP = 152[/tex]

Required

Determine x and WQP

From the attachment;

[tex]RQP = RQW + WQP[/tex]

Substitute 152 for RQP, 31 + x for RQW, 139 + x for WQP

[tex]152 = 31 + x + 139 + x[/tex]

Collect Like Terms

[tex]152 - 31 - 139 = x + x[/tex]

[tex]-18 = 2x[/tex]

Divide both sides by 2

[tex]\frac{-18}{2} = x[/tex]

[tex]x = -9[/tex]

To solve for RQW; substitute -9 for x in RQW = 31 + x

[tex]RQW = 31 + (-9)[/tex]

[tex]RQW = 31 -9[/tex]

[tex]RQW = 22[/tex]

25). WZ = 30

26). VY = 42

Step-by-step explanation:

In the figure attached,

V, W, X, Y and Z are collinear.

VZ = 52, XZ = 20 and WX = XY = YZ

21). Since XZ = 20

     XY + YZ = 20

     WX + WX = 20 [Since, XY = WX = YZ]

     2(WX) = 20

     WX = 10

22). VZ = VW + WX + XY + YZ = 52

     VW + 3(YZ) = 52 [Since, WX = XY = YZ]

     VW + [tex]3(\frac{XZ}{2})[/tex] = 52

     VW + [tex]\frac{3}{2}\times 20[/tex] = 52

     VW = 52 - 30 = 22

25). WZ = 3(WX)

The height of a triangle is 4 inches. Greater than twice it's base. The area of the triangle is no more than 168 in.². Which any quality can be used to find the possible lengths, x, of the base of the triangle

Answers

Step-by-step explanation:

this problem seeks to test our knowledge on word problems and algebra

Solution

let the base be x, and

the height h = 2x+4

We know that area of a triangle is given as

[tex]A= \frac{1}{2} b*h[/tex]

substituting our given values we have

[tex]168= \frac{1}{2} x*(2x+4)\\\\168= \frac{2x^2+4x}{2} \\\\168= x^2+2x\\\\[/tex]

re-arranging we have

[tex]x^2+2x-168=0\\\\[/tex]

we can now find two factors that will add up to give 2 and multiply to give -168

they are 14 and -12

[tex]x^2-14x+12x-168=0\\\\x(x-14)+12(x- 14)=0\\\\x+12=0\\\\x=-12\\\\x-14=0\\\\x=14[/tex]

The possible base of the triangle is 14 in

and the height is

[tex]h= 2x+4\\\\h=2(14)+4\\\\h= 28+4\\\\\h= 32 in[/tex]

A square image of an object on a video game has an initial side length of 25 pixels. To make the object appear closer, the side length of the square is increased by 10 pixels per second. This length change is represented by the function s(t) = 25 + 10t, where t is time in seconds. If the area of the square is A(s) = sa, find the formula for the area as a function of time, and then determine A(s(3)). A(t) equals +2+ t + 625 The area of the square image after 3 seconds is square pixels.​

Answers

Answer: A(t) = 100t^2 + 500t + 625

3,025 square pixels

Step-by-step explanation:

A function assigns the values. The area of the square image after 3 seconds is 3,025 sq. pixels.​

What is a Function?

A function assigns the value of each element of one set to the other specific element of another set.

A.) The area of the video game will be,

A(s) = [s(t)]²

A(s) = (25+10t)²

A(s) = 625 + 100t² + 500t

A(s) = 100t² + 500t +625

B.) The value of A(s(3)) will be,

A(s(t)) = 100(25+10t)² + 500(25+10t) + 625

A(s(t)) = 10,000t² + 50,000t + 62,500 + 12,500 + 5,000t + 625

A(s(t)) = 10,000t² + 55,000t + 75,625

A(s(3)) = 10,000(3)² + 55,000(3) + 75,625

A(s(3)) = 270,000 + 165,000 + 75,625

A(s(3)) = 510,625

The area of the square image after 3 seconds is,

A(s) = 100t² + 500t +625

A(3) = 100(3)² + 500(3) +625

A(3) = 900 + 1500 +625

A(3) = 3,025

Hence, The area of the square image after 3 seconds is 3,025 sq. pixels.​

2/3c=18 what does c equal to

Answers

Answer: 27

Step-by-step explanation:

Answer:

c = 27

Step-by-step explanation:

Solve for c:

(2 c)/3 = 18

Hint: | Multiply both sides by a constant to simplify the equation.

Multiply both sides of (2 c)/3 = 18 by 3/2:

(3×2 c)/(2×3) = 3/2×18

Hint: | Express 3/2×2/3 as a single fraction.

3/2×2/3 = (3×2)/(2×3):

(3×2)/(2×3) c = 3/2×18

Hint: | Express 3/2×18 as a single fraction.

3/2×18 = (3×18)/2:

(3×2 c)/(2×3) = (3×18)/2

Hint: | Cancel common terms in the numerator and denominator of (3×2 c)/(2×3).

(3×2 c)/(2×3) = (2×3)/(2×3)×c = c:

c = (3×18)/2

Hint: | In (3×18)/2, divide 18 in the numerator by 2 in the denominator.

18/2 = (2×9)/2 = 9:

c = 3×9

Hint: | Multiply 3 and 9 together.

3×9 = 27:

2 and 3 you have to draw

4a. 90 degree angle

4b. 180 degree angle

5a. 112 degrees

5b. 145 degrees

Step-by-step explanation:

for 5 you just subtract the given values from 360

Answer:

1a) A

(both B and C intersect at A)

1b) not sure

2a) draw 270 degree angle

360/4 = 90

90+90+90 = 270 = 3/4

2b) draw an angle less than 90 degree to get an acute angle

3a) first draw a 90 degree angle then divide the angle into two half and you ll get an angle of 45 degrees

90/2 = 45

but since you re not allowed to use compass or protactor so you might not get exact 45 but near to it

3b) draw a 90 degree angle facing downward and thats 270 degree

hope you get what im trying to say if not you can ask me again

4a) acute angle (90 degree)

4b) reflex angle (180 degree)

5a) 112 degree

118 + 130 + x = 360

248 + x  = 360

x  = 360 - 248

x  = 112

5b) 145 degree

360 - 215 = 145

im posting the solutions and the answers of your previous questions here

6a) a = 60 degree

6b) b = 27 degree

because sum of interior angles of a triangle is 180

7a) b = 60 degree and a = 30 degree

7b) x = 36 degree and x = 36 degree

isosceles triangle has 2 same angles and 1 different

x + x + 108 = 180

2x + 108 = 180

2x = 180 - 108

2x = 72

x = 72/2

x = 36

8a) x = 95 degree

8b) a = 100 degree

9) steps;

draw a line segment QR

draw 120 degree angle at point Q

now open the compass of 2cm (or of your own choice) and draw a small arc from point Q such that it intersects line PQ and QR and name that point between QR as O

now from point O, open your compass of same measurement and draw an arc that cuts the previous arc

now draw a line from point Q to join the new formed arc

now using a protactor measure both the newly formed angles

Answers

Answer:

(B) Subtract 3x from both sides of the equation, and then divide both sides by 2.

Can't read the second question fully.

(A) 0.53

Step-by-step explanation:

Number 1:

If we have the equation [tex]3x + 2 = 5x[/tex], our first goal is to get rid of the x term on one side.

To do this we can subtract 3x from both sides. This leaves our equation to [tex]2=2x[/tex]. To find x, we want to divide both sides by 2 since 2x divided by 2 is just x. Our goal is to isolate x.  This leaves [tex]x=1[/tex].

I couldn't read Number 2 fully - I'm sorry :c

Number 3:

Given the equation [tex]3(x+0.2)=2.2[/tex], we want to isolate x on one side.

To do this, we first apply the distributive property to the left side.

[tex]3x + 0.6 = 2.2[/tex]

Now subtract 0.6 from both sides:

[tex]3x=1.6[/tex]

And divide both sides by 3.

[tex]x=0.5\overline{3}[/tex]

This rounds to 0.53.

Answer:

Step-by-step explanation:

Equation

The first step is to subtract 3x from both sides.

3x - 3x + 2 = 5x - 3x

2 = 2x

The next step is to divide by two. That's the 2 in front of the two x.

2/2 = 2x/2

1 = x

So the answer must be B

You have ​$250 comma 000 in an IRA​ (Individual Retirement​ Account) at the time you retire. You have the option of investing this money in two​ funds: Fund A pays 2.4​% annually and Fund B pays 7.4​% annually. How should you divide your money between Fund A and Fund B to produce an annual interest income of ​$9 comma 000​?

Answers

Answer:

$190,000 goes to fund A while $60,000 goes to fund B to earn an annual interest income of $9,000

Step-by-step explanation:

Here, we are interested in knowing the way the money should be divided between the interest rates to give an annual interest totaling $9,000.

Let’s have the amount going to Fund A as $x while $y is the amount going to Fund B.

Although, we do not know the value of these amounts, we know that they both total $250,000

Thus, mathematically;

x + y = 250,000 •••••••••••(i)

Now also, let’s work with the percentages to get the interests:

For fund A;

2.4% of x = interest

2.4/100 * x = 2.4x/100

For fund B;

7.4% * y = interest

7.4/100 * y = interest

7.4y/100 = interest

Adding both gives a total of $9,000

Mathematically, that would be;

2.4x/100 + 7.4y/100 = 9,000

Multiply through by 100;

2.4x + 7.4y = 900,000 •••••••(ii)

From i, x = 250,000 -y

Substitute this into ii

2.4(250,000-y) + 7.4y = 900,000

600,000 -2.4y + 7.4y = 900,000

Collecting like terms, we have;

7.4y-2.4y = 900,000-600,000

5y = 300,000

y = 300,000/5

y = $60,000

But x = 250,000 - y

x = 250,000 - 60,000

x = $190,000
