If ΔRST congruent to ΔNPQ, which of the following is true? A. ∠R congruent to ∠P B. ∠R congruent to ∠Q C. ∠T congruent to ∠P D. ∠T congruent to ∠Q

Answers

Answer:

Step-by-step explanation:

The order of the expression for congruent shapes indicate the

corresponding vertices between the two shapes that are congruent.

The option which is true is D. T = Q.

Reasons:

The given statement is; ΔRST ≅ ΔNPQ

By Corresponding Parts of Congruent Triangle are Congruent, CPCTC, we

have; The sides on ΔRST are congruent to the corresponding sides of ΔNPQ

Therefore;

RS ≅ NP

RT ≅ NQ

ST ≅ PQ

By CPCTC, we have that the angles on ΔRST are congruent to the corresponding angles of ΔNPQ

Therefore;

∠R ≅ ∠N

∠S ≅ ∠P

∠T ≅ ∠Q

Which gives, by definition of congruency;

∠R = ∠N

∠S = ∠P

∠T = ∠Q

Therefore, the true statement is D. T = Q.

What is an exponent?

Exponential notation is the form of mathematical shorthand which allows us to write complicated expressions more succinctly. An exponent is a number or letter is called the base. It indicates that the base is to raise to a certain power. X is the base and n is the power.

Where t is the number of hours

Then the population of the bacteria after 180 hours will be

[tex]\rm P = 100 \times 2^{t/60} \\\\P = 100 \times 2 ^{180/60}\\\\\rm P = 100 \times 2^{3}\\\\\rm P = 100 \times 8\\\\\rm P = 800[/tex]

Answer:

k = 5/7; y = 5vw/(7z)w = 18/5; y = 10vw/zy = 3/2; k = 96v = 5/6; k = 8y = 168/5; y = 6vw/z

Step-by-step explanation:

As with other forms of direct and inverse variation, the "constant of variation" (k) is the constant multiplier in the equation. "Varies directly" means the independent variable is in the numerator. "Varies inversely" means the independent variable is in the denominator. The variation equation can be solved for missing values of constants or variables.

The equation for "varies directly with v and w, and inversely with z" means the equation is of the form ...

  y = k·v·w/z

Then the values of v or w are ...

  v = y·z/(k·w)

  w = y·z/(k·v)

__

a)

  k = y·z/(v·w) = 5·24/(12·14) = 5/7; the equation is y = 5·v·w/(7·z)

b)

  w = y·z/(k·v) = 18·8/(10·4) = 18/5; the equation is y = 10·v·w/z

c)

  k = 3/2 (read from the equation); y = (3/2)v·w/z = 3·16·24/(2·6) = 96

d)

  k = 8 (read from the equation); v = y·z/(k·w) = 20·2/(8·6) = 5/6

e)

  y = k·v·w/z = 6·12·7/15 = 168/5; the equation is y = 6·v·w/z

3. Use Structure Shari is drawing a tree diagram

12-sided game piece and spinning the pointer of
a 4-section spinner. Does it matter if Shari starts
the tree diagram with the game piece outcomes
or the spinner outcomes? Explain.

Answers

The sample space of Shari's tree diagram is the total possible outcomes of rolling the game piece and spinning the pointer.

It doesn't matter if Shari starts with the spinner or the game piece

How to determine the tree diagram

The experiment involves:

Rolling a 12-sided game pieceSpinning the pointer of a 4-section spinner

If Shari starts with the game piece, the sample size (n) would be:

n = 12 * 4

n = 48

If Shari starts with the spinner, the sample size (n) would be:

n = 4 * 12

n = 48

Notice that the sample size remains unchanged irrespective of what he starts with

Hence, it doesn't matter if Shari starts with the spinner or the game piece

to solve m + 9 = 45, should you add or subtract 9 from both sides of the equation

Answers

Answer:

subtract 9 from both sides

Step-by-step explanation:

m + 9 = 45 ( subtract 9 from both sides )

m = 36

Answer:

Subtract

Step-by-step explanation:

You should subtract since the equation says to add.

You basically do the opposite of what it says.

For example, if it was m - 9 = 45 you would add 9 on both sides, but in this case, you would subtract since its m + 9 = 45

m + 9 = 45

subtract nine by 9 and 45:

m = 36

36 + 9 = 45

a) Write down all the possible outcomes.
b) Find the probability that Magnus gets a head and a 3.

Answers

The possible outcomes of the fair coin and the dice is the sample space

The list of possible outcomes is: {H1,H2,H3,H4,H5,H6,T1,T2,T3,T4,T5,T6}The probability of getting a head and a 3 is 1/12

How to list the possible outcomes

The items are given as:

Coin = 1

Dice = 1

The sample space of both items are:

Coin = {H,T}
Dice = {1,2,3,4,5,6}

So, the list of possible outcomes is: {H1,H2,H3,H4,H5,H6,T1,T2,T3,T4,T5,T6}

The probability of getting a head and a 3

From the above list, there is only one outcome that has a head and a 3 out of 12 possible outcomes

So, the probability of getting a head and a 3 is:

p = 1/12

How large of a circle would it

Answers

The largeness of the circle is an illustration of proportions

Using the assumed parameters, the circle must be 200 times larger than a normal circle

How to determine the size of the circle?

The question is incomplete; so I will make use of assumed values

Assume that a normal circle of radius r can take up to 50 toy cars.

When the normal circle is replaced by a larger circle of radius R to take up to 10000 toy cars, the size of the circle must be:

Size = 10000/50

Divide

Size = 200

This means that the circle must be 200 times larger than a normal circle

What is the measure of ∠A in the image below?

Answers

Answer:

A

Step-by-step explanation:

3x and x + 30 are vertically opposite angles and are congruent , then

3x = x + 30 ( subtract x from both sides )

2x = 30 ( divide both sides by 2 )

x = 15

Then

∠ A = 3x = 3(15) = 45°

See <A and x+30 are opposite angles .

We know that opposite angles are equal

so

3x=x+302x=30x=15

Now

<A=3x=45°

Explanation and Answer:

The graph of y=[tex]x^2[/tex] is a parabola (it looks like a u) that intersects the graph at the origin. These are all shifted variations of that graph, so from that you can figure out their formula by visualizing it.

You can also try substituting numbers into the equations and drawing a graph from that.

Graph A is the y=x^2, shifted to the left, so it becomes [tex]y=x^2+x[/tex]. It's +x because now negative numbers can be gotten from the equation, as compared to before when x^2 gives only positive numbers.

Graph B is [tex]y=x^2+3x[/tex] . Similar to graph A, but now it moves down by more units, because of the 3x.

Graph C is [tex]y=-x^2+2[/tex]. Imaging y=x^2 flipped, it changes from looking like a u to n. That's y=[tex]-x^2[/tex]

Graph D is [tex]y= x^2-x[/tex]. The opposite of Graph A.
