Answer:

D - 10^2+24^2

Step-by-step explanation:

So, there are a few important things here to go over:

First off, the formula for area of square is l*w, but since a square's length and width are equal, this will just be l^2.

Secondly, the formula for pythagreons theorm is a^2+b^2=c^2. This is what we will use to find the side length of A.

So, we see that there is a triangle that is made up of the top side of the organge square, the left side of the green square, and the right side of the blue square.

To find the righ side of the blue square, we need to use the pythagreons theorm.

This is because the hypotenuse of the triangle(C), is also the right side of square A.

The A and B that we use to find C in pythagreons theorm we know is 24 and 10.

Lets plug this in:

10^2+24^2=c^2

=

100+576=676

Normallu, to find the length of the side, we would root the 676. However, since area is x^2, and we found ^2=676, we are fine.

So tecnically, 10^2+24^2=A.

Or:

[tex]10^2+24^2=A[/tex]

This looks like D

Answer:

3/2 cm^2 or 1.5 cm^2

Step-by-step explanation:

Remark

This is another one of those very poorly design questions where a lot is taken for granted. There is nothing to show the the black square has an area of 1/4 square cm. or the white square is 1/2 cm^2. You are left to speculate, and you should never have to guess a dimension from a diagram.

That said here are the assumptions

White square area = L * W

L = 1 (which comes from 1/2 of 2)

W = 1/2

Area = 1 * 1/2 = 1/2

There are two them them so their area = 1

The black squares are 1/2 * 1/2 = 1/4 square cm. There are two of them so their total area = 1/2 square cm.

Total of the white and black squares = 1 + 1/2 = 1 1/2 or 3/2 square cm.

Answer: The age of Mr. Lang's youngest son is 7 years old.

Step-by-step explanation:

Let's start by listing the factors of 84. The factors of 84 are 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42 and 84.

We can only use numbers that are under 19 since we must add up to that total. Now we are left with 1, 2, 3, 4, 6, 7, 12, and 14,

1 can't be an option since 18 is not there to pair with it to add together for 19. For the same reason we can eliminate 2, 3, 4, 6, and 14.

Now we are left with 7 and 12. Let's see is they will work.

7+12=19

7×12=84

It works! Since 7 is the smaller number that's the age of Mr. Lang's youngest son.

Answer:  directly north

=============================================

Explanation:

A one quarter turn is 1/4 of 360 degrees, so it's (1/4)*360 = 90 degrees.

Three quarters of a full turn is (3/4)*360 = 270, or you could triple the 90 to get 90*3 = 270.

Rick starts facing directly east. Then he rotates 270 degrees clockwise to end up facing directly north. Refer to the diagram below.

Answer:

160

Step-by-step explanation:

If the scale factor is 4, we would have to multiply the height and width by 4

4*5=20

4*4=16

Now to find the area of the triangle using the formula (20*16)/2

That equals to 160

Question 4

---------------------

Explanation:

There are 5 green, 9 red, and 6 blue. That makes 5+9+6 = 20 total marbles. Of this total, 6 are blue. The probability of picking blue is 6/20 = 3/10

==============================================================

Question 5

---------------------

Explanation:

The open hole at 6 means we do not include this value as part of the shaded solution set. So we either have "less than" or "greater than".

We go with "less than" since the shaded region is to the left. This describes all values smaller than 6.

If you had "or equal to" as part of the inequality, then you would have a filled in circle at the endpoint.

Answer: $15.21

Step-by-step explanation:

Given

Joe's lunch cost $13.00 without tax

He tipped the waiter with 17% of bill without tax

So, the amount of tip is

[tex]\Rightarrow 13\times 17\%\\\Rightarrow 13\times 0.17\\\Rightarrow \$2.21[/tex]

Total amount that food costs without tax is

[tex]\Rightarrow 13+2.21\\\Rightarrow \$15.21[/tex]

Answer:

Y=75x+125

Step-by-step explanation:

Your answer is correct. It is c. The equation is y=Mx+b where m is the slope and b is the y intercrept.

To get M (the slope), get the difference of y-y/x-x. You can use any value of y and x. So, 575-500/6-5=75/1 ot 75. Therefore 75 is m in the equation y=Mx+b.

To get b, you figure out what y is when x is 0. So, looking at the numbers, subtract 75 from 350, which means that  y is 275 when x is 2. Subtract 75 again to get 200 (275-75) when x is 1. Subtract 75 one more time to get y when x is 0. 200-75=125. 125 is the y intercept.

Going back to the equation y-Mx+b. Fill in m and b. Y=75x+125.

Answer:

Step-by-step explanation:

OS ≅ OU, so we will set those 2 expressions equal to each other and solve for y:

6y = 42 so

y = 7

Same goes for OT and OV:

x + 5 = 23 so

x = 18 and

SU = 84

We are given the equation below:

[tex] \large{ {p}^{2} = \frac{9}{36} }[/tex]

Use the property below:

[tex] \large \boxed{ {x}^{2} = \frac{a}{b} \longrightarrow x = \pm \frac{ \sqrt{a} }{ \sqrt{b} } \: \: (a \geqslant 0 \: \: and \: \: b > 0)}[/tex]

From the equation:

[tex] \large{p = \pm \frac{ \sqrt{9} }{ \sqrt{36} } } \\ \large{p = \pm \frac{3}{6} \longrightarrow p = \pm \frac{1}{2} }[/tex]

Hence the answer is p = ± 1/2.

Answer:

[tex]\text{B. }\triangle DKM[/tex]

Step-by-step explanation:

When naming a triangle or any polygon, the name should consists of either the center of the polygon or each of the vertices (points) of the triangle. In this case, no center is labelled, so we will use the vertices to name the triangle.

The vertices or points of the triangle are D, K, and M. Therefore, we name this triangle by writing a triangle symbol [tex]\triangle[/tex] followed by these vertices.

Unless you're comparing it to another polygon (e.g. writing a similarity statement), the order of which you list the vertices does not matter, but you should start with a point and move either clockwise or counterclockwise until you list every point. Therefore, the answer is [tex]\boxed{\text{B. }\triangle DKM}[/tex].

Answer:

7x + 2y = 1

Step-by-step explanation:

First we find the slope m of the line

The slope of a line that passes through 2 points x1, y1 and x2 , y2 is given as

m = (y2 - y1)/(x2 - x1)

Considering the points (–3, 11) and K(1, –3), the slope of the line m

= (-3-11)/(1 --3)

= -14/4

= 7/2

the line JK may be given as

y - 11 = -7/2(x - -3)

multiply through the equation by 2

2y - 22 = -7(x + 3)

2y - 22 = -7x - 21

7x + 2y = 22 - 21

7x + 2y = 1

Answer:

Answer:

y=50 and z=60 (vertically opposite)

x+60+y=180

or x+60+50=180

or x+110=180

or x=70

Answer:

Step-by-step explanation:

a.x = 95 degree

reason = being vertically opposite angles

x + 145 degree = 180 degree

x = 180 -145

x=35 degree

reason = being linear pair

b.40 + x =90 degree

x = 90 - 40

x = 50 degree

reason = being perpendicular

y = x + 40

y = 50 + 40

y = 90 degree

reason = being vertically opposite angles

c.50 + 60 + x=180 degree

110 + x =180

x = 180-110

x = 70 degree

reason = being linear pair

z = 60 degree

reason = being vertically opposite angles

y = 50 degree

reason = being vertically opposite angles

d. x = 80 +10

x =90 degree

reason = being vertically opposite angles

y + x =180 degree

y + 90 =180

y = 180 - 90

y = 90 degree

reason = being linear pair

If u want nore help please follow

Step-by-step explanation:

STEP 1: Draw a straight line with a ruler. STEP 2: Put the pin of a compass at the end of the line you want to bisect. Set the compass to more than half the length of the line, and draw an arc crossing the line. STEP 3: Keep the width of the compass the same, and from the opposite end of the line draw another arc.

Answer:

First, in your compass take more than half of the given line, i.e, if the line is 5 centimeters, then in the compass take a length more than five centimeters.

Second, Draw an arc, by keeping the compass needle on one end of the line, and do the same by keeping it on the other end.

Two of the arcs will intersect at a point.

Third, do the same, but in the back-ward direction, as in the below of the line. These two will also intersect.

Lastly, draw a line connecting the intersection of the top and below arcs.

I couldnt add the last pic because of the 5 attachments rule. Like I said in the last rule, just join the two arc intersections.
