Choose Yes or No to tell whether 0 is a solution for the inequality 10p - 8 less than or equal to 12.
Yes
No
Answers
Answer:
yes
Step-by-step explanation:
Answer:
Yes
Step-by-step explanation:
To find out if the inequality 10p - 8 ≤ 12 is true if p is 0, replace p with 0.
10(0) - 8 ≤ 12
0 - 8 ≤ 12
-8 ≤ 12
-8 is less than 12 so Yes, p as 0 works.
(Ex: In fact, the largest value where this is true is 2. All negative numbers work with this inequality.)

Answer:
Answer:
x = 15 , m∠ CDF = 59° , m∠FDE = 73° , m∠CDE = 132°
Step-by-step explanation:
* Lets explain how to solve the problem
- The m∠ CDF = (3x + 14)°
- The m∠ FDE = (5x - 2)°
- The m∠ CDE = (10x - 18)°
- We need to find the value of x and the measure of each angle
∵ Point D is the vertex of the three angles
∵ The ray DF is between the rays DC and DE
∴ m∠ CDE = m∠ CDF + m∠ FDE
∵ m∠ CDE = (10x - 18)°
∵ m∠ CDF = (3x + 14)°
∵ m∠ FDE = (5x - 2)°
- Substitute the measures of these angles in the equation above
∴ 10x - 18 = (3x + 14) + (5x - 2)
- Add the like terms in the right hand side
∴ 10x - 18 = (3x + 5x) + (14 - 2)
∴ 10x - 18 = 8x + 12
- Subtract 8x from both sides and add 18 to both sides
∴ 10x - 8x = 12 + 18
∴ 2x = 30
- Divide both sides by 2
∴ x = 15
- Substitute the value of x in the measure of each angle to find it
∴ m∠ CDF = 3(15) + 14 = 59°
∴ m∠ FDE = 5(15) - 2 = 73°
∴ m∠ CDE = 10(15) -18 = 132°
9514 1404 393
Answer:
∠CDF = 59°
∠FDE = 73°
∠CDE = 132°
Step-by-step explanation:
We can use the angle sum theorem to relate the angles:
∠CDF + ∠FDE = ∠CDE
(3x +14) +(5x -2) = (10x -18) . . . . . divide by " (presumably, degrees (°))
8x +12 = 10x -18 . . . . . collect terms
30 = 2x . . . . . . . . . . . . add 18-8x
15 = x . . . . . . . . . . . . . . divide by 2
Then the angle measures are ...
∠CDF = (3x +14)° = (3(15) +14)° = 59°
∠FDE = (5x -2)° = (5(15) - 2)° = 73°
∠CDE = (10x -18)° = (10(15) -18)° = 132°

A lumber company is making boards that are 2857.0 millimeters tall. If the boards are too long they must be trimmed, and if the boards are too short they cannot be used. A sample of 16 is made, and it is found that they have a mean of 2858.7 millimeters with a variance of 100.00. A level of significance of 0.05 will be used to determine if the boards are either too long or too short. Assume the population distribution is approximately normal. Is there sufficient evidence to support the claim that the boards are either too long or too short
Answers
Answer:
The test statistic 't' = 0.68 < 2.1314 at 0.05 level of significance
Null Hypothesis is accepted
There is no sufficient evidence to support the claim that the boards are either too long or too short
Step-by-step explanation:
Step(i):-
Mean of the Population (μ) = 2857.0 millimetres
size of the sample 'n' = 16
Mean of the sample (x⁻) = 2858.7 millimetres
The Variance of the sample (S²)= 100.00
Standard deviation of the sample (S) = √100 =10
Degrees of freedom = n-1 =16-1 =15
Level of significance =0.05
Tabulated value = [tex]t_{\frac{0.05}{2} , 15} = t_{0.025,15} = 2.1314[/tex]
Step(ii):-
Null Hypothesis :H₀ : There is no sufficient evidence to support the claim that the boards are either too long or too short
Alternative Hypothesis: H₁:There is sufficient evidence to support the claim that the boards are either too long or too short
Test statistic
[tex]t = \frac{x^{-} -mean}{\frac{S}{\sqrt{n} } }[/tex]
[tex]t = \frac{2858.7 -2857}{\frac{10}{\sqrt{16} } }[/tex]
t = 0.68
The calculated value = 0.68 < 2.1314 at 0.05 level of significance
Null Hypothesis is accepted
Final answer:-
There is no sufficient evidence to support the claim that the boards are either too long or too short

Jessica needs to get her bicycle fixed. A mechanic charges $30 per hour of labor, and $45 for parts. The total cost for fixing Jessica's bicycle is $90. How
long did it take the mechanic to fix Jessica's bicycle?
Answers
Answer:
It took the mechanic an hour and a half so 1.5 hour.
Step-by-step explanation:
If the mechanic charges $30 per hour + $45 for parts=75. If the total cost was $90 then 90(total cost)-75(for the first hour +parts) =15 and 30(cost of one hour)/2 is 15 which is half hour.

The sum of the measures of the angle in any triangle is 180 degrees. In triangle ABC, angles A and B have the same measure, while angle C is 42 degrees larger than each of the other two angles. Find the measure of angle C.
Answers
Answer:
88°
Step-by-step explanation:
we can say the two base angles are each x°
the vertex angle (∡C) is (42 + x)°
add them all and set equal to 180°
x + x + x + 42 = 180
3x + 42 = 180
3x = 138
x = 46
∡C = 46 + 42 = 88°
If angle C is 42 degrees larger than each of the other two angles. then measure of angle c is 88 degrees.
What is Angle Sum property?The sum of angles of a triangle are 180 degrees.
Given that,
The sum of the measures of the angle in any triangle is 180 degrees. In triangle ABC, angles A and B have the same measure, while angle C is 42 degrees larger than each of the other two angles. we can say the two base angles are each x°
the vertex angle (∡C) is (42 + x)°
add them all and set equal to 180°
x + x + x + 42 = 180(By angle sum property)
3x + 42 = 180
Shift 42 to RHS
3x = 180-42
3x = 138
Divide both sides by 3.
x = 46
∡C = 46 + 42 = 88°
Therefore angle C is 88°.

Answer:
The answer is C and E.
Step-by-step explanation:
I just took the assignment and it is C and E.
The expression that represents the population after 5 decades is
100,000 x [tex]2^5[/tex] or 100,000 x 2 x 2 x 2 x 2 x 2.
Options C and E is the correct answer.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
2x + 4 = 8 is an equation.
We have,
The population of the city = 100,000
Population doubles every decade.
This means,
Population after 1 decade.
= 100,000 x 2
= 200,000
Population after 2 decades.
= 200,000 x 2 x 2
= 800,000
We can write an expression for the population after x decade.
= 100,000 x [tex]2^x[/tex]
The population after 5 decades.
= 100,000 x [tex]2^5[/tex]
= 100,000 x 2 x 2 x 2 x 2 x 2
= 100,000 x 32
= 3200,000
Thus,
The expression is 100,000 x [tex]2^5[/tex] or 100,000 x 2 x 2 x 2 x 2 x 2.
