tabel optional
PLEASE HELP ME PASS 8th GRADE
Answer:
61.8 feet to nearest tenth.
Step-by-step explanation:
USING THE PYTHAGORAS THEOREM:
55*2 = 21^2 + h^2 where h is the height of the top of the ladder from the ground.
h^2 = 55^2 - 21^2
= 2584
h = √2584
= 50.83 ft.
So the height of the building
= 11 + 50.83
= 61.83 feet.

A bag contains 5 red marbles, 10 white marbles, and 9 blue marbles. You draw 3 marbles out at random, without replacement. What is the probability that all the marbles are red?
Answer:
5/24
Step-by-step explanation:
Number of red marbles = 5Number of white marbles = 10Number of blue marbles = 9Total number of marbles = 24P(getting red marbles) = (Number of red marbles)/(Total number of marbles)P(getting red marbles) = 5/24What is the area of the circle?
Answer:
530.93
Step-by-step explanation:
area of a circle = πr²
where r = radius
here we are given the diameter
to convert to radius , we divide by 2
so radius = 26 / 2 = 13
so we have A = πr²
==> plug in r = 13
A = π13²
==> evaluate exponent
A = 169π
==> multiply 169 and π
A = 530.93 ( approximately )

To solve this problem, we need to use the theorem which states that the sum of angles in a triangle is equal to 180 degrees. The value of m<FED is equal to 120 degrees. From the diagram given, m<CBD is complimentary with m<BED
Sum of Angles in a TriangleThe value of m<FED can be calculated by summing the entire entity and equating to 180 degrees.
Data;
m<FED = (16x - 8)m<EFD = 35m<EDF = 2x + 9[tex]35+(16x-8)+(2x+9) = 180[/tex]
Reason: The sum of angles in a triangle is equal to 180 degrees.
But we would need to solve for the value of x.
[tex]35+(16x-8)+(2x+9) = 180\\35 + 16x - 8 + 2x + 9 = 180\\36+ 18x = 180\\180 - 36 = 18x\\18x = 144\\x = \frac{144}{18} \\x = 8[/tex]
Let's substitute the value of x into m<FED
[tex]m < FED = 16x - 8\\x = 8\\m < FED = 16(8) - 8 \\m < FED = 128 - 8\\m < FED = 120^0[/tex]
The value of m<FED is equal to 120 degrees.
From the diagram given, m<CBD is complimentary with m<BED

Answer:
Angle E equals 45 degrees and angle J equals 35 degrees.
If all angles of two triangles match up with one another, then you have yourself a pair of two similar triangles.
Hope it helps, have a fantastic day.
Step-by-step explanation:
We all know from geometry that all the angles of a triangle add up to 180 degrees.
We can form the following equation:
[tex]100 + 35 + E = 180[/tex]
[tex]E[/tex] here represents the measure of angle E.
Add together like terms:
[tex]135 +E = 180[/tex]
Then subtract 135 from both sides:
[tex]E = 45[/tex]
We can, likewise, form another equation for angle J :
[tex]100 + 45 + J = 180[/tex]
Add together like terms:
[tex]145 +J = 180[/tex]
Then subtract 145 from both sides:
[tex]J = 35[/tex]
Angle E equals 45 degrees and angle J equals 35 degrees.
If all angles of two triangles match up with one another, then you have yourself a pair of two similar triangles.

Formula's:
Area of triangle:
1/2 × base × height
Area of rectangle:
length × width
Area of the figure:
= area of triangle + area of rectangle's
= 1/2 × 11 × 7 + 3 × 4 + 5 × 3 + 5 × 2 + 7 × 5
= 110.5 yd²
Answer:
110.5 yd²
Step-by-step explanation:
Separate the figure into 1 triangle and 3 rectangles.
(see attached image)
Area 1
Area of a triangle = 1/2 × base × height
= 1/2 × (7 + 2 + 2) × 7
= 1/2 × 11 × 7
= 38.5 yd²
Area 2
Area of a rectangle = width × length
= 3 × (5 + 2 + 2)
= 3 × 9
= 27 yd²
Area 3
Area of a rectangle = width × length
= 5 × (5 + 2)
= 5 × 7
= 35 yd²
Area 4
Area of a rectangle = width × length
= 2 × 5
= 10 yd²
Total Area
Area 1 + Area 2 + Area 3 + Area 2 = 38.5 + 27 + 35 + 10

A packaging factory is open from Monday to Saturday.
In a particular week, 15,000 packets were packed on Monday and the factory was also closed on Tuesday.
If no less than 100,000 packets should be packed in that week, what is the minimum equal number of packets that must be packed per day for the remaining days?
packets
Answer:
A minimum of 21250 packets per day.
Step-by-step explanation:
If Monday produced 15,000 packets, and Tuesday was closed they produced 15,000 packets in 2 days.
The factory is open 6 days a week.
They need 100,000 packets.
They have 15,000 packets.
6 subtract 2 is 4.
100,000 subtract 15,000 is 85,000.
They need 85,000 packets in 4 days.
That is a minimum of 21250 packets per day.
21250 is minimum equal number of packets that must be packed per day for the remaining days
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Given that packaging factory is open from Monday to Saturday.
On monday 15,000 packets were packed.
On tuesday the factory is closed.
The factory has to pack in that week of 100000 packets.
As already 2 days completed by packing 15000
The remaining packets should be packed within 4 days.
The remaining packets are 100000-15000
85000
This should be done with in four days of time.
We need to find the minimum equal number of packets that must be packed per day for the remaining days.
Divide 85000 by 4
85000/4
21250
Hence, 21250 is minimum equal number of packets that must be packed per day for the remaining days
