The pairs of triangles appear to be congruent are Triangles 1 and 4,  Triangles 1 and 3 and  Triangles 3 and 4, that is option B, option C and option E. This can be obtained by understanding the concept of congruence.

In the question, Triangle 2 is larger than the other triangles.

Triangle 1, Triangle 3 and Triangle 4 appears to have the same size and shape.

Thus Triangle 1, Triangle 3 and Triangle 4 appears to be congruent to each other.

Hence the pairs of triangles appear to be congruent are Triangles 1 and 4,  Triangles 1 and 3 and  Triangles 3 and 4, that is option B, option C and option E.

Answer:

y=-2x+4

Step-by-step explanation:

2x+y-1=0

2x+y=0+1

2x+y=1

y=1-2x

y=-2x+1

y=mx+b where m=slope and b=y-intercept

parallel means same slope,

so the slope would still be -2.

y-y1=m(x-x1)

y-2=-2(x-1)

y=-2x+2+2

y=-2x+4

Answer:

Length = x-5

Step-by-step explanation:

Length= Area/width

Length = x³-5x²+3x-15/ x²+3

Re-arrange the numerator:

Length=x³+3x-5x²-15/x²+3

Take common from the numerator:

Length=x(x²+3) -5(x²+3)/x²+3

Length=(x²+3)(x-5)/x²+3

Length = x-5

Thus the answer is x-5 ....

the equation is S=30w+450

to find the answer just replace the w by 14

multiply 30 by 14 to get 420 and add 450 to it to get 870

The equation relating the total amount of money 'S' in the savings account to the number of weeks 'W' that Ryan has been saving is S = 450 + 30W. By substituting W with 14 in this equation, we find that Ryan will have $870 in his savings account after 14 weeks.

In this case, Ryan had started with $450 in his savings account. His weekly contribution to the savings is $30. So the total amount of money 'S' in the savings account after 'W' weeks could be represented by the equation S = 450 + 30W.

Now, if you want to find out the total amount of money in the savings account after 14 weeks, just substitute W = 14 into the equation. Thus the equation becomes S = 450 + 30*14 = 450 + 420 = $870.

Therefore, Ryan will have $870 in his savings account after 14 weeks.

Step-by-step explanation:

ΔACX is an isosceles triangle, so ∠AXC = ∠XAC.  We'll call the measure of this angle x°.

∠AXC and ∠BXC are supplementary, so ∠AXC + ∠BXC = 180.  That means ∠BXC = 180 − x.

ΔBXC is an isosceles triangle, so ∠XBC = ∠XCB.  We'll call the measure of this angle y°.

Angles of a triangle add up to 180, so:

y + y + (180 − x) = 180

2y = x

y = x/2

∠ACX and ∠XCB are complementary, so ∠ACX + ∠XCB = 90.

x + y = 90

x + x/2 = 90

3/2 x = 90

x = 60

Therefore, ∠AXC = ∠XAC = 60°.

Answer: OPTION A

Step-by-step explanation:

It is important to remember the "Angle Addition Postulate" in order to solve this exercise.

You have this larger angle:

 [tex]\angle AVB[/tex]

According to the "Angle Addition Postulate", if the point "C"  is in the interior of [tex]\angle AVB[/tex], then the measure of this angle can be obtained by adding the angle [tex]\angle AVC[/tex] and the angle [tex]\angle CVB[/tex].

You can observe in the figure that:

 [tex]m\angle AVC=39\°\\\\\mangle CVB=23\°[/tex]

Then you get that:

[tex]m\angle AVC+m\angle CVB=m\angle AVB\\\\39\°+23\°=62\°[/tex]

Therefore, the correct answer is Option A.

Answer:answer is actually C

Answer:

Choice C

Step-by-step explanation:

Because,

50 is min

75 is middle

100 is max

The correct data set is {50, 60, 60, 75, 75, 85, 85, 100}

Given,

The box plot with number line titled percent with 50 as the minimum, 60 as quartile 1, 75 as the median, 85 as quartile 3, and 100 as the maximum.

We need to determine the following data sets are represented in the box plot.

Let us segregate the following data set by taking the help of a minimum value.

Now, we require a data set that has a minimum value of 50.

There is only one data set given in the option that is a minimum value of 50.

Thus, data set is {50, 60, 60, 75, 75, 85, 85, 100}.

Cross-checked the above data set with more information that is already given in the question.

We required 60 as quartile 1, 75 as the median, 85 as quartile 3, and 100 as the maximum.

Thus, all the above requirements are fulfilled by the data set {50, 60, 60, 75, 75, 85, 85, 100}.

Hence, the correct data set is {50, 60, 60, 75, 75, 85, 85, 100}

Explanation

Answer

First option: 1/3x = y - 3

Answer:

7/15

Step-by-step explanation:

first recognise that 3/3 is a whole pizza and so is 5/5.

Secondly make all the numbers to have the same denominator

So times both denominators of the fractions together; 5x3=15

Now find 1/3 of 15. Do this by dividing 15 by 3. This equals 5.

So 1/3 is equal to 5/15

Now do the same for 1/5. 15 divided by 5, this equals 3.

So 1/5 is equal to 3/15

Now that we know that the whole pizza is 15/15

We minus 1/3 from 15.

15-5=10.  So we now have 10/15 left.

now we know that 'x' is representative of the amount of pizza Tom gave to his bother.

10/15 - 3/15 = x

x = 7/15

So out of the whole pizza (15/15), tom ate 5/15 and was left with 3/15 meaning he gave 7/15 to his brother.

Final answer:

Tom ate 1/3 of the pizza and was left with 1/5 of it, so he gave away 2/15 of the pizza to his brother.

Explanation:

The question is asking which fraction of a pizza Tom gave to his brother. To find out, we know Tom ate 1/3 of the pizza and ended up with 1/5 of it. The fraction that Tom gave his brother is the difference between what he had after eating and what he was left with, thus:

1/3 - 1/5 = (5 - 3) / 15

So, 2/15 of the pizza was given to Tom's brother.

Answer:

y = - 34

Step-by-step explanation:

Given y varies directly as x then the equation relating them is

y = kx ← k is the constant of variation

To find k use the condition y = - 51 when x = 3

k = [tex]\frac{y}{x}[/tex] = [tex]\frac{-51}{3}[/tex] = - 17

y = - 17x ← equation of variation

When x = 2, then

y = - 17 × 2 = - 34

Final answer:

To find the value of y when x = 2 in a direct variation relationship, determine the constant of variation first and then substitute the given values to find the unknown.

Explanation:

The relationship given is that y varies directly with x. To find y when x = 2, you can use the direct variation formula.

First, find the constant of variation by using the values given: y = kx. Plug in y = -51 and x = 3 to find k.

Once you have k, solve for y when x = 2 using y = kx.

Therefore, when x = 2, y = -34.

Answer:

25/81

Step-by-step explanation:

1000³ = (10³)³ = 10⁹ = 2⁹ × 5⁹

For a factor to be a perfect square, the exponents must be even.  For example:

2⁰ × 5⁰, 2⁰ × 5², 2² × 5⁰, etc.

There are 5 even exponents between 0 and 9 for each 2 and 5.  So the number of perfect square factors is 5×5 or 25.

The total number of factors is 9×9 or 81.

So the fraction of positive integer factors that are perfect squares is 25/81.

25/81 is the fraction of the positive integer factors of 1000^3,

1000^3 = (10^3)^3 = 10^9 = 2^9 x 5^9

Perfect square factors have even exponents.

There are 5 even exponents between 0 and 9 for each 2 and 5.

Answer:

3x+4 Ralph is currently 12 years old.

Step-by-step explanation:

You can find the equation by reading the scenario given. When you read it, it says that Ralph is 3 times as old as Sara and since her current age is going to be used to represent x you will first get 3x. That automatically eliminates the second and third choice given. It then says the equation is for Ralph's age in four years which means to add four to the equation. This gives you 3x+4 as your equation.

When something is tripled and then in a few years it is doubled, it is easiest to first try the number that is being added. So in this case the number is four. When you multiply 4 by 3 you get 12. If Sara is 4 she'll turn eight in four years and if Ralph is 12 he'll turn 16 in four years. 16 divided by 2 is 8 which shows you that Ralph is currently 12
