What is the measure of angle JHN.
Answer:
it's a)25
Step-by-step explanation:
angle MHL and JHN+NHK should be the same, they both are 95 degrees
Answer:
45°
Step-by-step explanation:
first of all find X
(3x+20) - (x+25) =x + 20
3x+20-x-25=x+20
3x-x+20-25=x+20
2x-5=x+20
collect like terms
2x-x=20+5
x=25°
recall JHN= (x+20)°
x=25
JHN=((25)+20)°
JHN=(25+20)°
JHN=45°

Find the total surface area of this prism where
the cross-section is an isosceles triangle.
13 cm
5 cm
10 cm
24 cm
Answer:
The total surface area of the prism is 620 cm²
Step-by-step explanation:
The total area of the prism = lateral area + 2 (area of the cross-section)
The lateral area = perimeter of the cross-section × height
∵ The cross-section of the prism is an isosceles triangle
∵ The sides of the triangle are 13 cm, 13 cm, 24 cm
∵ The perimeter of the triangle is the sum of its sides
∴ The perimeter = 13 + 13 + 24 = 50 cm
∴ The perimeter of the cross-section = 50 cm
∵ The height of the prism is 10 cm
→ Use the rule of the lateral area above to find it
∴ The lateral area of the prism = 50 × 10 = 500 cm²
∵ The area of the triangle = [tex]\frac{1}{2}[/tex] × base × height
∵ The base of the triangle = 24 cm
∵ The height of the triangle = 5 cm
∴ The area of the triangle = [tex]\frac{1}{2}[/tex] × 24 × 5 = 60 cm²
∴ The area of the cross-section = 60 cm²
→ Substitute the lateral area and the area of the cross-section in the rule
of the total surface area above
∵ The surface area = 500 + 2(60)
∴ The surface area = 500 + 120
∴ The surface area = 620 cm²
∴ The total surface area of the prism is 620 cm²
which is greater -4/5 or -7/8
Answer:
-7/8 is greater
Step-by-step explanation:
-4/5=-0.8
-7/8=-0.875
To find the greater fraction, we can use the butterfly method.
Cross multiply the numerator by the denominator.[tex](-\frac{4}{5} )(- \frac{7}{8} )[/tex]
[tex]-\frac{4\times8}{5\times7}=\frac{32}{35}[/tex]
Therefore, [tex]-\frac{4}{5}[/tex] is greater than [tex]-\frac{7}{8}[/tex].
4) Name The Angle Pair Represented And Solve For x. *
37°
(6x - 11)
Answer:
x = 8
Step-by-step explanation:
The attached figure shows the angle pair representation.
Here, two lines are cut by a transversal. It means the corresponding angles are equal i.e.
37 = 6x-11
37+11 = 6x
6x = 48
x = 8
Hence, the value of x is 8.

Solve for W: P=2L + 2W
A. W=P-L
B. W= 1/2P - L
C. W= 1/2 P + L
D. W= 2P - L
Answer:
B
Step-by-step explanation:
[tex]P=2L+2W[/tex]
[tex]P-2L=2W[/tex] (Subtract 2L from both sides of the equation)
[tex]2W=P-2L[/tex] (Symmetric Property of Equality)
[tex]W=\frac{P-2L}{2}[/tex] (Divide both sides of the equation by 2)
[tex]W=\frac{P}{2} -\frac{2L}{2}[/tex] ("Split" the fractions)
[tex]W=\frac{1}{2}P-L[/tex] (Simplify)

a road crew can repave 1/15 miles of road each hour. they must repave a road that is 3/5 miles long. how long will it take the crew to repave the road?
Answer:
9 hours
Step-by-step explanation:
For this problem, we simply need to rewrite the goal length, 3/5 miles, into our ratio of time length equivalence, 1 hour per 1/15 miles. To do this we find the common denominator to be 15 and rewrite it as so:
3/5
= 3*3 / 5 * 3
= 9 / 15
And since it takes 1 hour per 1/15 mile of road, we can perform the division to find the amount of time:
9/15 / 1/15
= 9/15 * 15/1
= ( 9 * 15 ) / ( 15 * 1 )
= 9 / 1
= 9
Hence, it will take the crew 9 hours to repave the road.
Cheers.
Answer:9 hours

A factory produced a batch of handheld video games, but 4% of the games were found to be defective. If the batch had 250 games in all, how many games in the batch were not defective?
A.
240
B.
150
C.
100
D.
10
Answer:
A) 240 games are not defective
Step-by-step explanation:
1% of 250 = 2.5
*4 *4
4% of 250 = 10
250 - 10 = 240
240 games are not defective

The perimeter of a regular decagon is 513m.
State the length of one of its sides.
Step-by-step explanation:
Decagon = 10-sided polygon
Perimeter of 10 sides = 513m
Perimeter of 1 side = 513m/10 = 51.3m.
If a radioactive isotope has a half-life of 6 hours and 12 milligrams is initially present, how much will
be present in 24 hours?
Answer:0.75 milligrams will be present in 24 hours
Step-by-step explanation:
Step 1
The formula for radioactive decay can be written as
N(t)=No (1/2)^(t/t 1/2)
where
No= The amount of the radioactive substance at time=0=milligrams
t 1/2= the half-life= 6 hours
t=24 hours
N(t) = the amount at time t
Step 2--- Solving
N(t)=No (1/2)^(t/t 1/2)
=N(t)=12 x ( 1/2) ^ (24/6)
= 12 x (1/2) ^4
= 12 x 0.0625
= 0.75 milligrams

Two triangles are said to be congruent if all three corresponding sides are equal and all the three corresponding angles are equal in measure.
1.The triangle is congruent by ASA postulate
If two angles and the included side of one triangle are congruent to two angles and the included side of a second triangle, then the triangles are congruent.
2. The triangle is congruent by SSS postulate
If all three sides of a triangle are congruent to corresponding three sides of other triangle then the two triangles are congruent.

Step-by-step explanation:
Nadine conducted an experiment with four possible outcomes. Trevor conducted the same experiment, but he doubled the number of trials. Which statements are true? Select two options. Trevor has more experimental outcomes than Nadine. Trevor’s sample space is greater than Nadine’s. Trevor’s experimental probability is more likely closer to the theoretical probability than Nadine’s. Nadine’s experimental probability is more likely closer to the theoretical probability than Trevor’s. Nadine has more experimental outcomes than Trevor.
Answer:
A and C
Step-by-step explanation:
Nadine and Trevor both conducted an experiment but Nadine conducted with four possible outcomes and Trevor doubled the trials, therefore, Trevor will have more experimental outcomes than Nadine because he doubled the trials. Moreover, Trevor's experimental probability is more likely closer to theoretical probability than Nadine's, therefore option 'A' and 'C' are correct.
Answer:
Trevor has more experimental outcomes than Nadine.
Trevor’s experimental probability is more likely closer to the theoretical probability than Nadine’s.

Answer:
(1)
Step-by-step explanation:
Given
[tex]\frac{2x}{a}[/tex] + b = c ( subtract b from both sides )
[tex]\frac{2x}{a}[/tex] = c - b ( multiply both sides by a to clear the fraction )
2x = a(c - b) ← distribute
2x = ac - ab ( divide both sides by 2 )
x = [tex]\frac{ac-ab}{2}[/tex] → (1)
