What whole number is 13 divided by 1 2/3 closest to?
Answer:
I think it's 14
The whole number is 13 divided by 1 2/3 closest is 8.
We need to find what the whole number is 13 divided by 1 2/3 closest.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Let the unknown whole number be x.
Here, 1 2/3 can be written as 5/3.
Now, x=13/(5/3)
=13 × 3/5
=39/5 = 7.8
≈8
Therefore, the whole number is 13 divided by 1 2/3 closest is 8.

Answer:
The angles measures are [37.5°], [75°], and [67.5°]
Step-by-step explanation:
Let us revise a fact about any triangle
In any triangle, the sum of the measures of the interior angles of a triangle is 180°We will use this fact to solve the question
∵ The measures of the angles of the given triangle are x°, 2x°, (x + 30)°
→ By using the fact above, equate their sum by 180°
∴ x + 2x + x + 30 = 180
→ Add the like terms in the left side
∴ (x + 2x + x) + 30 = 180
∴ 4x + 30 = 180
→ Subtract 30 from both sides
∴ 4x + 30 - 30 = 180 - 30
∴ 4x = 150
→ Divide both sides by 4 to find the value of x
∴ [tex]\frac{4x}{4}=\frac{150}{4}[/tex]
∴ x = 37.5
→ Substitute x by 37.5 in each angle
∴ x° = 37.5°
∴ 2x° = 2(37.5)° = 75°
∴ (x + 30)° = (37.5 + 30)° = 67.5°
The angles measures are [37.5°], [75°], and [67.5°]
To justify the answer substitute x by 37.5 in the equation
∵ 4x + 30 = 180
∵ x = 37.5
→ Left side = 4(37.5) + 30 = 150 + 30 = 180
→ Right side = 180
∵ Left side = Right side
∴ x = 37.5 is a correct answer.
Determine the value z* that satisfies the conditions below. (Round all answers to two decimal places.) (a) Separates the largest 3% of all z values from the others z* = 1.81 Incorrect: Your answer is incorrect. (b) Separates the largest 1% of all z values from the others z* = 2.33 Correct: Your answer is correct. (c) Separates the smallest 4% of all z values from the others z* = 1.76 Incorrect: Your answer is incorrect. (d) Separates the smallest 10% of all z values from the others z* = 1.29 Incorrect: Your answer is incorrect.
Answer:
The answer is below
Step-by-step explanation:
The z score is used to determine by how many standard deviations the raw sore is above or below the mean.
a) For the largest of 3%:
P(z > z*) = 3%
P(z > z*) = 0.03
P(z > z*) = 1 - P(z < z*)
1 - P(z < z*) = 0.03
P(z < z*) = 1 - 0.03
P(z < z*) = 0.97
The z score that corresponds with 0.97 is 1.88. Hence:
z* = 1.88
b) For the largest of 1%:
P(z > z*) = 1%
P(z > z*) = 0.01
P(z > z*) = 1 - P(z < z*)
1 - P(z < z*) = 0.01
P(z < z*) = 1 - 0.01
P(z < z*) = 0.99
The z score that corresponds with 0.99 is 2.33. Hence:
z* = 2.33
c) For the smallest of 4%:
P(z < z*) = 0.04
The z score that corresponds with 0.04 is -2.65. Hence:
z* = -2.65
d) For the smallest of 10%:
P(z < z*) = 0.1
The z score that corresponds with 0.1 is -1.28. Hence:
z* = -1.28

classify each angle as right, acute, or obtuse. then use a protractor to measure the angle to the nearest degree
The angle ∠MPR is an obtuse angle, ∠RPN is a right angle and ∠NPS is an acute angle.
What is an angle?An angle is a geometry in plane geometry that is created by 2 rays or lines that have an identical terminus.
The identical endpoint of the two rays—known as the vertex—is referenced as an angle's sides.
In another word, the angle is the measurement of the angular distance for example for linear motion we have a meter inch but for angular rotation, we don't have the measurement so the angle is useful to measure the angular rotation.
Given the angles ∠of MPR, ∠RPN, and ∠NPS.
Now,
The right angle is the angle with 90° (perpendicular rays) so ∠RPN will be the right angle.
An angle less than 90° will be an acute angle so ∠NPS will be acute angle.
An angle greater than 90° will be an obtuse angle so ∠MPR will be an obtuse angle.
Hence "The angle ∠MPR is an obtuse angle, ∠RPN is a right angle and ∠NPS is an acute angle".

Answer:
m<2 = 70 degrees, m<4 = 110 degrees, m< 8 = 110 degrees, m < 7 = 70 degrees
Step-by-step explanation:
According to the consecutive interior angles theorem, we get that m< 1 and m< 2 equals 180 degrees.
So, we will get 110 + m< 2 = 180
m<2 = 70 degrees
m<2 and m<4 are supplementary angles, so they both add up to 180 degrees.
70 + m<4 = 180
m<4 = 110 degrees.
m<1 and m<8 are vertical angles, so they will both be of equal measure.
So, m<8 = 110 degrees.
Lastly, m<8 and m<7 are supplementary angles, so they add up to 180 degrees.
110 + m< 7 = 180
m< 7 = 70 degrees.
Hope this helps!

Answer:
A = 60
B = 55
C = 65
Step-by-step explanation:
The sum of the angles of a triangle is 180
A + B+C = 180
x+ x-5 + 65 = 180
Combine like terms
2x+60 =180
Subtract 60 from each side
2x= 180-60
2x= 120
Divide by 2
2x/2 = 120/2
x= 60
A = 60
B = 60-5= 55
C = 65
Answer:
Angle A: 60°
Angle B: 55°
Angle C: 65°
Step-by-step explanation:
180° = 65° + x + (x-5)
Subtract 65° from both sides
115° = x+(x-5)
115° = 2x-5
Add 5 to both sides
120° = 2x
Divide both sides by 2
x = 60°
Angle A: 60°
Angle B: 55°
Angle C: 65°

Find u in terms of m,g and v in this equation E = m/2g(v²-u²)
Step-by-step explanation:
E = m/2g(v²-u²)
2g×E = 2g×m/2g(v²-u²)
2Eg = m(v²-u²)
2Eg = mv² - mu²
mu²= mv² -2Eg
mu²/m = mv² -2Eg /m
u²= v² -2Eg
u = √v²-√2Eg

Answer:
No solution
Step-by-step explanation:
→ Expand brackets
3 ( 2x + 2 )- 3x = 6 + 3x ⇒ 6x + 6 - 3x = 6 + 3x
→ Simplify
6x + 6 - 3x = 6 + 3x ⇒ 3x + 6 = 6 + 3x

Determine which graph, f(x) = or g(x) = 16, rises more steeply. Explain.
Answer:
Sample Response: g(x) rises more steeply than f(x) because the value of a in f(x) is 4, whereas the value of a in g(x) is 16. This means that f(x) is a vertical stretch of the square root function by a factor of 4, while g(x) is a vertical stretch of the square root function by a factor of 16. Both functions will contain the point (0, 0), but f(x) would contain the point (1, 4) and g(x) would contain the point (1, 16), which is a steeper rise from the point (0, 0).
