Answer: D 90
Step-by-step explanation:
One way to do this follows: Find the ratio, r, which when multiplied by each of the four numbers in the ratio produces the actual number of parts present:
4r + 11r + 9r + 6r = 60
Summing these up results in 30r = 60, so r is 2.
There are 4(2), or 8, nails,
11(2), or 22, screws,
9(2), or 18, washers, and
6(2), or 12, brackets.
Note that 8 + 22 + 18 + 12 = 60 (total number of parts)
If 5 carpenters have identical boxes, there will be 5(18), or 90, total washers.

What is the volume of the prism?
A prism has hexagon bases with each side 12 centimeters. From the side of the base to the center of the base is 10 centimeters. The height of the prism is 9 centimeters.
Answer:
To find the volume of a regular hexagonal prism, we can use the formula V = 3ash, where a = apothem length, s = length of a side of the base, and h = height of the prism

for question 1
Area of Base B =45×25 = 1125 cm²
perimeter of base P = 2(45+25) = 140 cm
Height = 15 cm
Using the formula
Surface area = 2B + Ph
A = 2×1125 + 140×15= 4350 cm²
Voume = Bh = 1125×15= 16875 cm³
For question 2,
Area of base = 7× 5/2= 17.5 cm²
Perimeter of base = (7+7+7) = 21 cm
Surface area = 2B + Ph
Surface area of prism = 2×17.5+ 21×10 = 245cm²
Volume = Bh = 17.5×10 = 175 cm³

Gretchen made a paper cone to hold a gift for a friend. The paper cone was 14 inches high and had a
radius of 4 inches. Find the volume of the paper cone to the nearest tenth. Use 3.14 for it.
The volume of the paper cone is about
in?
Answer:
268.0 in²
Step-by-step explanation:
refer to attached graphic as reference
volume of cone, V = (1/3) πr²h
in our case, we are given r = 4" and h = 16"
substituting this into equation:
V = (1/3) πr²h
= (1/3) ·(3.14) · (4)²· (16)
= 267.94667 in²
= 268.0 in² (nearest tenth)

Mrs. Murphy by balloons garlands paper lanterns and banners to decorate a school party she got three times as many bags of balloons as paper lanterns seven more garlands than paper lanterns and for banners she paid $5.25 for each banner $6.50 for each paper lantern five dollars for each bag of balloons and $3.50 for each garland how many of each kind of decoration did she purchase if she paid $145.50
Pls use format that is shown on screenshot ty
Answer:
Paper Lanterns: 4
Bags of Balloons: 12
Garlands: 11
Banners: 4
Step-by-step explanation:
Cost of lanterns is $6.50
Mrs. Murphy bought 4 lanterns
Multiply the cost of one lantern ($6.50) by the number of lanterns bought (4)
6.50 multiplied by 4 equals 26
Cost of banners is $5.25
Mrs. Murphy bought 4 banners
Multiply the cost of one banner ($5.25) by the number of banners bought (4)
5.25 multiplied by 4 equals 21
Mrs. Murphy bought 3 times as many balloons as she did lanterns
So, you multiply the number of lanterns bought (4) by 3
This gives you 12
You then multiply the cost of each balloon ($5.00) by the number of balloons bought (12)
5.00 multiplied by 12 equals 60
Mrs. Murphy bought 7 more garlands as she did lanterns
So, you add 7 to the number of lanterns bought (4)
7 plus 4 equals 11
To find the cost of the total garlands bought
You multiply the cost of each garland ($3.50) by the number of garlands bought (11)
3.50 multiplied by 11 equals 38.5
Now you can add up the costs of all the items
26+21+60+38.5=145.50
145.50 was the total amount she spent so you know it is the correct answer.

Answer:
2/3
Step-by-step explanation:
The slope is rise over run so all you have to do is make a triangle from the two points, count how many go up, which is 2, and how many go to the side, which is 3. The rise (2) goes on the top of the fraction, the run (3) goes on the bottom and then that's your answer.

Calculate the area of each rectangle and add the two areas to find the whole area.
First split the shape. You can split it where the 13 ends and the 8 starts.
Next, We know that Area = lw
Do, 13x6= 78
Next, Do, 8x4=32
Then add both areas to get:
78+32=110
So, Area = 110

need help with this question.
Answer:
-4
Step-by-step explanation:
it would be -9+5 which is basically 5-9=-4
so, the answer is -4.
Answer:
-4°C
Key:
( | | ) = these in between numbers is the absolute value. EXAMPLE: |-8| = 8
Step-by-step explanation:
If it was -9°C and it INCREASED by 5°C, you need to ADD.
-9°C + 5°C
*Because -9°C is a NEGATIVE NUMBER and is on the LEFT side of the number line, unlike 5°C, you need to count 5 units to the RIGHT of -9°C (Basically subtract the absolute values of each number (-9 = |9|) (5 = |5|) and make it either positive or negative, depending on which absolute value is the greatest (|9|).*
-9°C + 5°C OR |9| - |5|
|9°C| - |5°C| = |4°C| = -4°C
(because the greatest absolute value, |9|, is negative, the answer is too.)

Suppose you have a bag with 25 letter tiles in it and 7 of the tiles are the letter V. If you pick a letter tile at random from the bag, the probability that it is the letter V is 7/25
. Suppose another bag has 500 letter tiles in it and 250 of the tiles are the letter V. Write the probability of picking a tile that is the letter V as a fraction and as a percent. From which bag are you more likely to pick a tile that is the letter V?
The probability of picking a tile that is the letter V from the second bag is: As a fraction: 250/500 = 1/2 and As a percent: (1/2) x 100% = 50%.
What is probability?Probability is a measure of the likelihood that an event will occur. It is a number between 0 and 1, with 0 indicating that the event is impossible and 1 indicating that it is certain. The closer the probability is to one, the more likely it is that the event will occur.
Probability can be used to make predictions and decisions in a variety of fields such as finance, statistics, and so on.
It is also an important concept in comprehending probability laws and the behaviour of random events.
The probability of picking a tile that is the letter V from the second bag is:
As a fraction: 250/500 = 1/2
As a percent: (1/2) x 100% = 50%
Thus, comparing the probabilities, the second bag is more likely to contain a tile with the letter V since the probability of picking a V from the second bag is higher (1/2 or 50%) than from the first bag (7/25 or 28%).
