Answer:

2 1/2

Step-by-step explanation:

Area - 1/2(b)(h)

5/6 = (1/2)(2/3)(b)

5/6=2/6(b)

b=5/2

b=2 1/2

Answer:

The best statement to choose is D

Box B has a volume of 591 1/2cm³. She should choose Box B because it has greater volume.

step by step:

Step 1) 13/4 × 13/2 = 13/4 × 26/4 = 338/4 = 84 1/2 (84.5)

Step 2) 84 1/2 × 7 = 591 1/2 (591.5)

Box B = 591.5cm³   >   Box A = 185.25cm³

Answer:

r is also 60 degrees, p and q are both 120 degrees

Step-by-step explanation:

you add the 2 60s together because they are the same angles, then you subtract that number from 360, and then divide it by 2 because p and q are both the same, and you get the answer.

r is also 60 degrees, p and q are both 120 degrees

Step-by-step explanation:

you add the 2 60s together because they are the same angles, then you subtract that number from 360, and then divide it by 2 because p and q are both the same, and you get the answer. so yeah there you go

answer: 6(3h+5k)

To factor this, we can factor both variables and then get a multiplier outside the parentheses and the new variables inside. (Sorry if it’s confusing)

18h = 2*3*3*h

30k = 2*3*5*k

Both have 2*3, which is 6. This will be the multiplier. To get the new variables, divide the old variables by 6.

18h/6 = 3h

30k/6 = 5k

The signs should not change.

6(3h+5k)

Hope this helps!

Step-by-step explanation:

To subtract 3/8 from 2/3, we need to find a common denominator.

The least common multiple of 3 and 8 is 24.

So, we can convert 2/3 and 3/8 to have a denominator of 24:

2/3 = 16/24

3/8 = 9/24

Now we can subtract:

16/24 - 9/24 = 7/24

Therefore, 2/3 - 3/8 = 7/24.

Answer:

[tex]\frac{2}{5}[/tex]

Step-by-step explanation:

How about we try this:

Joe needs to plant tomatoes in his garden, but he needs to know the area before planting. What is the area of a rectangular garden that is [tex]\frac{2}{3}[/tex] wide and [tex]\frac{3}{5}[/tex] long?

To solve this problem:

The formula for area of a rectangle is [tex]A=lw[/tex] where l is the length and w is the width. This is the same as multiplying, which is done in the operation.

[tex]A=\frac{2}{3}\times \frac{3}{5}[/tex]

Multiply across

[tex]A=\frac{6}{15}[/tex]

Simplify the fraction by dividing by 3

[tex]A=\frac{2}{5}[/tex]

The area of the rectangle is [tex]\frac{2}{5}[/tex]

Under these conditions, plant B produced 12000 panels

We are told that 3% of the 9000 panels in plant A and 10% of "x" quantity in plant B are defective.
As it is not known how much plant B produces, but it is known that the grand total of defects is 7%, the total defective of separate plants are added and the value is equaled to the grand total of defects.

[tex]\begin{array}{l}\sf 0.03\times 9000 + 0.1b = 0.07\times(9000+b)\\\sf 270 + 0.1b = 630 + 0.07b\\\sf 0.1b-0.07b = 630-270\\ \sf 0.03b=360\\\raisebox{6pt}{$\sf b=\dfrac{360}{0.03}$}\\\therefeore\bf b=12000~panels\end{array}[/tex]

So, plant B produces 12000 panels

If you have any question about this solution, you can ask me in the comments :)

Answer:

8 students went to the science museum twice last year.

Step-by-step explanation:

It's pretty straightforward but just to give an explanation: So based on the graph, it seems like each green x is equal to one student. And on the bottom it tells us the numbers 0-5 are the number of times of trips students took. It tells you to calculate the amount students went EXACTLY twice, so look at how many green x's are at number 2 and that's the answer, 8.

Answer:

19

Step-by-step explanation:

85-66=19

Answer:

19

Step-by-step explanation:

19+66=85

85-19=66

66-85=19

Let x represent the amount of second chocolate that should be added.

First, 300 pounds of chocolate

1 to 7 = chocolate to caramel

Hence there are a total of eight pieces (1+7=8).

There are:

1/8 300 pounds cocoa

7/8 300 pounds caramel

Second chocolate: x pounds cocoa to caramel = 1 to 15 Hence, there are in total 16 parts (1+ 15 = 16)

There are:

Caramel: 15/16" x pounds Cocoa: 1/16" x pounds

Chocolate yield: 300 + x pounds

1 to 9 = chocolate to caramel

As a result, there are a total of ten pieces (1 + 9 = 10)

There are:

1/10 (300 + x) pound cocoa

9/10 (300 + x) pounds caramel

Because there is only one part cocoa in every chocolate, adding up the amounts of cocoa is simple:

1/8* 300+ 1/16* x = 1/10 * (300 + x)

300/8 + x/16 300/10 + x/10 =

75/2 + x/16 = 30 + x/10

75/230= x/10 - x/16

75/2 - 60/2 = 8x/80 - 5x/80

(75 - 60)/2 = (8x - 5x)/80

15/2 = 3x/80

80 15/2 = 3x

40 * 15 = 3x

600 = 3x

x = 600/3

200 pounds = x

As a result, the answer is 200.

Step-by-step explanation:

Answer: The perimeter of crater lake is 17.27 miles.

Step-by-step explanation:

The shape of the lake is like a circle

The diameter of lake = d = 5.5 miles

∵ shape pf lake is circle, so the diameter of circle = d = 5.5 miles

Let The perimeter of crater lake = p miles

Now, As we know

The perimeter of circle = \pi × diameter

the value of \pi = 3.14

Or, p =  pi × d

Or, p = pi × 5.5 miles

Or, p =  3.14 × 5.5 miles

∴ p = 17.27 miles

So, The perimeter of circle = perimeter of lake = p = 17.27 miles

Hence, The perimeter of the crater lake is 17.27 miles.
