a number close to 1,772 that is easily divisible by 90

Problem 2

Why not? Well it's because the angles do not match up perfectly.

The triangle on the left is a 30-60-90 triangle; while the triangle on the right is a 40-50-90 triangle. The numbers mentioned are the angle values.

Only the "90"s match up, but everything else does not. We need to have three pairs of congruent angles to be able to use the angle angle (AA) similarity theorem.

Answer:

y=x+1.75

4x-2y = 4

The answer is (3. 75, 5.5)

Step-by-step explanation:

If you plot the two equations on Desmos' Graphing Calculator, you will see that the solution is intersected at (3.75, 5.5).

Explanation:

We can make use of the symmetry of the problem and properties of similar triangles.

Here's a "paragraph proof."

Draw line OP perpendicular to chord MN, such that P lies on line MB. Let the point of intersection of OP with chord MN be designated point Q. Line OP bisects angle MON, so has measure y/2.

Triangles OPM and MPQ are similar (by AA similarity; both right triangles contain angle OPM), so angle QMP ≅ angle MOP. As we observed above, angle MOP has measure y/2, so angle QMP has measure y/2.

Angle BMN is another name for angle QMP, so it has measure y/2.

Additional comments

By the HL congruence postulate, the perpendicular bisector of chord MN divides triangle MON into two congruent right triangles. (OM≅ON, MQ≅NQ). That means ∠MOQ≅∠NOQ, so OQ bisects angle MON, as we say above.

__

Another way to come to the desired conclusion is to recognize that for any point X on long arc MN, angle MXN will have measure y/2. (inscribed angle theorem) This remains true in the limit as X approaches M. As X approaches M, secant XM approaches tangent line MB. So, in the limit, angle BMN is y/2.

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

Answer:

explicit  definition: [tex]a_n=5n-4[/tex]

recursive definition: [tex]a_n=a_{n-1}+5[/tex]

Therefore,

Using the general form of arithmetic sequence: [tex]a_n=a+(n-1)d[/tex]

[tex]\implies a_n=1+(n-1)5[/tex]

Step-by-step explanation:

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

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}

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

Hence, the probability of getting a head and a 3 is 1/12

If the initial population of the bacteria is 100, then the population of the bacteria after 180 hours will be 800.

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.

A colony of 100 bacteria doubles in size every 60 hours.

The exponential relation will be given below.

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

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:

what's the problem?

Step-by-step explanation:

do u have a picture to show us?

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.

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.

Answer:For the answer to this It has me stuck between A and B

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

Now

Option A is correct

Answer:

$820.00

Step-by-step explanation:

x = price yesterday (initital price)

If it is 67% off, then the price is 33% of the initial.

x(.33) = 270.60

divide .37 on both sides

x = 820.00

The price of the suit yesterday is $820.00.

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

The experiment involves:

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

Answer:

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)

__

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

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

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

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

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