Answer:
1000 less 35% == 650
so 250 given to charity
total cost making the pins was 1000x 1.10 = 1100
so you need to find 60 percent of 650 =390
and 40 percent of 650 = 260
so then you need to find the cost 390 x 3 pounds each so × this and gives you 1170 cost sold for intotal
Then you have 260 ÷2 = 130 x 5 = 650
so you have 650+1170 = 1820 - 1100 cost to make =720 pounds
think this right

* Find the length of BD.
A
9514 1404 393
Answer:
BD = 17
Step-by-step explanation:
The Pythagorean theorem can be used twice:
BC^2 + AC^2 = AB^2
BC = √(AB^2 -AC^2) = √(25^2 -24^2) = √49 = 7
__
Likewise, ...
DC = √(AD^2 -AC^2) = √(26^2 -24^2) = √100 = 10
Then ...
BD = BC +DC = 7 + 10
BD = 17

Write the ratio of the first measurement to the second measurement. Compare in millimeters Diameter of ball A: 33mm Diameter of ball B: 5.4 cm
Answer:
The ratio of first measurement to second measurement in millimeters is 11:18
Step-by-step explanation:
Given that:
Diameter of ball A = 33 mm
Diameter of ball B = 5.4 cm
1 cm = 10 mm
5.4 cm = 10*5.4 mm
5.4 cm = 54 mm
Ratio of diameter of ball A to diameter of ball B.
33 : 54
Simplifying the ratio
11 : 18
Hence,
The ratio of first measurement to second measurement in millimeters is 11:18

Answer:
D. x>[4]
Plzzzzz give me Brainliest!!!!!
Answer:
D. x > 4
Step-by-step explanation:
You have to do the opposite operations to get the variable on one side of the equation by itself.
4 - x + 4 = 8 - 4
x = 4
You only switch the comparison sign if you mutliply or divide by negative numbers when you do opposite operations to get the variable on one side of the equation by itself.

The missing number in the arithmetic sequence 60, 51, ___, 33 is:
Answer:
42
Step-by-step explanation:
In this question, we have the find the rate of change in the sequence.
To find this, we need to find how much the sequence is changing by.
We know from 60 to 51 is -9, so we know that our sequence is changing by -9.
To find our unknown number, we would subtract 9 from 51.
51 - 9 = 42
Our missing number in the sequence is 42.
We can check our answer by subtracting 9 from 42. This gives us our next number, which is 33.
42 would be your answer.

Answer:
x = 6y = 18Step-by-step explanation:
The applicable rules of exponents are ...
(a^b)/(a^c) = a^(b-c)
(a^b)^c = a^(bc)
__
[tex]\left(\dfrac{a^3b^4}{a^2b}\right)^6= (a^{3-2}b^{4-1})^6 =a^{1\cdot6}b^{3\cdot6}=\boxed{a^6b^{18}}[/tex]

Which costs the last per ounce, a 20 ounce soda for $0.60, 68 ounce for $2.38, or 100 ounce for $3.32? Explain how you got your answer.
9514 1404 393
Answer:
20 oz for $0.60
Step-by-step explanation:
You can determine the least-cost item by comparing costs at the same size. (This can be done using mental arithmetic.)
68 ounces is between 3 and 4 times the size of 20 ounces. If the costs were the same, 68 ounces would cost between 3·$60 = $1.80 and 4·$60 = $2.40. The cost of 68 ounces is closer to $2.40 than 68 is to 80, so we conclude the 20-ounce soda costs less.
The cost of 100 ounces at the 20-ounce price would be 5·$0.60 = $3.00, which is less than the cost of the 100-ounce soda. Again, the 20-ounce soda is cheaper.
The least cost per ounce is the 20-ounce soda.
__
If you like, you can actually find the cost per ounce by dividing the cost by the ounces. Those results are shown in the attached table. The 20-ounce soda costs the least.
The ration of child to teen to adult tickets sold at a water park on Saturday was 4:1:2. A total of 294 tickets were sold. How many child tickets were sold?
Answer: 168 child tickets were sold.
Step-by-step explanation:
Given: The ratio of child to teen to adult tickets sold at a water park on Saturday was 4:1:2.
Let the number of child tickets = 4x , teen tickets = x , adult tickets = 2x
Total tickets = x+4x+2x = 7x =294
[tex]\Rightarrow\ x=\dfrac{294}{7}\\\\\Rightarrow\ x=42[/tex]
Number of child tickets = 4(42) = 168
Hence, 168 child tickets were sold.
Samantha makes a conjecture that the product of two odd integers is always an odd integer. Which choice is the best proof of her conjecture? CLEAR CHECK Look at these different examples: 7 × 3 = 21, 5 × 9 = 45, 11 × 3 = 33. So the product of two odd numbers must be odd. Every time you multiply two odd numbers, the product is an odd number. Let (2a + 1) be an odd number. Let (2b + 1) be another odd number. The product 2(2ab + a + b) + 1 is a multiple of 2 plus 1, which is an odd number. Let a and b both represent odd numbers, and let a × b be an odd number. Therefore, a × b = b × a, which shows that the product of two odd numbers is odd.
Answer:
Let (2a + 1) be an odd number. Let (2b + 1) be another odd number. The product 2(2ab + a + b) + 1 is a multiple of 2 plus 1, which is an odd number.

Help me please 9w+4= 2w+32
Answer:
w=4
Step-by-step explanation:
9w+4=2w+32
-2w -2w
7w+4=32
-4 -4
7w=28
w=4
Answer:
w = 4
Step-by-step explanation:
How to solve...
You have your equation 9w + 4 = 2w + 32, now you take 4 and subtract on both sides, so you will subtract it to 4 and 32. You get 28 as your answer. Now leave that alone, next you will take 2w and subtract it on both sides, when you subtract 2w to 9w you will get 7w. Now just do 28 divided by 7, which is 4. So w = 4. Hope this helps!
9w + 4 = 2w + 32
- 4 = - 4
--------------------------
9w = 2w + 28
-2w = -2w + 28
---------------------------
7w = 28
7w = 7w
---------------------------
w = 4
