five consecutive multiples of 3 add up to 105. What is the second smallest number
89 points!
Answer:
18
Step-by-step explanation:
Let's call the first number n. The next four numbers will be n + 3, n + 6, n + 9 and n + 12. Then, we have
n + n + 3 + n + 6 + n + 9 + n + 12 = 105
5n + 30 = 105
5n = 75
n = 15
The second smallest number is n + 3 which is 15 + 3 = 18.

square root of, 29, end square root.
Where does the point T(5,-2)T(5,−2)T, left parenthesis, 5, comma, minus, 2, right parenthesis lie?
Answer:
Point T is on the circle
Step-by-step explanation:
To check where the point lies, we need to find its distance to the center of the circle.
The distance between two points (x1, y1) and (x2, y2) is given by:
[tex]distance = \sqrt[2]{(x2 - x1)^{2} + (y2 - y1)^{2}}[/tex]
If the first point is O(0,0) and the second is T(5, -2), we have:
[tex]distance = \sqrt[2]{(5 - 0)^{2} + (-2 - 0)^{2}}[/tex]
[tex]distance = \sqrt{29}[/tex]
The distance between the points is equal the radius of the circle, that means the point T is on the circle.
Answer:
inside the circle

Triangle MNO is dilated to form new triangle PQR. If angle
is congruent to angle R. what other information will prove that the two triangles are similar by the AA similarity postulate?
Side ON is congruent to side RQ.
Angle Nis congruent to angle
Side MN is congruent to side PQ.
Angle M is congruent to angle Q.
Please help
Answer:
Angle N is congruent to Angle Q.Step-by-step explanation:
If triangles MNO and PQR are similar, then the corresponding sides are propotional and the corresponding angles are congruent.
Angle M corresponds to Angle P.Angle N corresponds to Angle Q.Angle O corresponds to Angle R.So, we know by gvein that angles O and R are congruent. We only need another angle congruence to use the AA postulate of similarity.
Therefore, the right answer is the second choices, because Angle N must be congruent to Angle Q.
Answer: B: Angle N isn’t congruent to angle Q
Step-by-step explanation: You have to follow the letters MNO and PQR. We know O is congruent to R to get another angle we would use Angle N and Q because of the order since Angle M and angle Q aren’t in the same order and we’re not dealing with sides only Angles.

Use z- table Round your answers to four decimal places. Do not round intermediate calculations. a. What is the probability that the sample proportion will be within ±0.03 of the population proportion? b. What is the probability that the sample proportion will be within ±0.08 of the population proportion?
Answer:
A) 0.61351
Step-by-step explanation:
Sample proportion = 0.4
Sample population = 200
A.) proprobaility that sample proportion 'p' is within ±0.03 of population proportion
Statistically:
P(0.4-0.03<p<0.4+0.03)
P[((0.4-0.03)-0.4)/√((0.4)(.6))/200 < z < ((0.4+0.03)-0.4)/√((0.4)(.6))/200
P[-0.03/0.0346410 < z < 0.03/0.0346410
P(−0.866025 < z < 0.866025)
P(z < - 0.8660) - P(z < 0.8660)
0.80675 - 0.19325
= 0.61351
B) proprobaility that sample proportion 'p' is within ±0.08 of population proportion
Statistically:
P(0.4-0.08<p<0.4+0.08)
P[((0.4-0.08)-0.4)/√((0.4)(.6))/200 < z < ((0.4+0.08)-0.4)/√((0.4)(.6))/200
P[-0.08/0.0346410 < z < 0.08/0.0346410
P(−2.3094 < z < 2.3094)
P(z < -2.3094 ) - P(z < 2.3094)

Write the equation of the line with the following characteristics. Parallel to y=7x+2 through the point (0,0)
Answer:
y = 7x - 5
Step-by-step explanation:
y = 7x+2 we see the gradient is 7 (x 0) + 2 = Since the line is parallel to y= 7x +2
The new line has a slope of 7 + 2 as the intercept at y.
y - 0 = 7 ( x - 0)
y - 1/7 = x - 0
y = 7x - 5
As 7 -5 = 2
Hence equation of line becomes y=7x.
What is Equation of line?You must ensure that both equations have the same slope in order to find an equation for a line that is parallel to another. The m reflects your slope value in the general equation of a line, y=mx+b.
How to solve?Now given line y=7x+2 ,this line is parallel to another line which passes through origin(0,0)
Hence putting 0,0 in general equation to find equation of parallel line
⇒y=mx+c
⇒0=m(0)+c
⇒0=c
where m=7 as parallel lines have same slope.
Hence equation of line becomes y=7x.

Let's analyze the answer choices.
A. 6 2/3
The bottom number of the fraction is a 3, so this cannot be correct.
B. 16/18
The denominator here is 18, so this choice is also incorrect.
C. 6/7
In this fraction the numerator is a 6, but the denominator is a 7, so this choice is also wrong.
D. 1/6
This choice is the correct answer. The denominator, or bottom number is a 6.

Question #2 [tex]5x+9\leq 4[/tex]
The model represents an equation.
What value of x makes the equation true?
Record your answer and fill in the bubbles on your answer document. Be sure to use the
correct place value. x = -3.8
X = 2.25
x=4.12
x=2
The value of x in the model that makes the equation true is: b. x = 2.25
We can find the value of x that makes the equation true by applying our knowledge of how to model equations.
From the image given:
On your left, we have -x, in three places which can be translated to as: [tex]3 \times -x = -3x[/tex]On the left also, we are given [tex]10 \times 1 = 10[/tex]We can model the left side as:[tex]-3x + 10[/tex]
On your right, we have x in five places which can be translated to as: [tex]5 \times x = 5x[/tex]On the right also, we are given [tex]8 \times -1 = -8[/tex]We can model the left side as:[tex]5x - 8[/tex]
The equation would be:[tex]-3x + 10 = 5x - 8[/tex]
Solve the equation for the value of x. Collect like terms.[tex]-3x - 5x = - 8 - 10\\\\-8x = -18[/tex]
Divide both sides by -8[tex]x = \frac{-18}{-8} \\\\x = 2.25[/tex]
Therefore, the value of x in the model that makes the equation true is: b. x = 2.25

write this trinomial in factored form 4b^2 + 17b + 15
Answer:
(b + 3)(4b + 5)
Step-by-step explanation:
Given
4b² + 17b + 15
Consider the factors of the product of the b² term and the constant term which sum to give the coefficient of the b- term.
product = 4 × 15 = 60 and sum = 17
The factors are 12 and 5
Use these factors to split the b- term
4b² + 12b + 5b + 15 ( factor the first/second and third/fourth terms )
= 4b(b + 3) + 5(b + 3) ← factor out (b + 3) from each term
= (b + 3)(4b + 5) ← in factored form
