and the difference in price is .49
so 1.1 ounces cost .49

Jordan has to solve this division problem: 42 divided by 7 = ?
Which of the following equations can he use?
42 + 7 = ?
7 x 42 = ?
? x 7 = 42
7 divided by 42 = ?
Answers
The correct equation that Jordan can use to solve the division problem 42 divided by 7 is:
? x 7 = 42
So, the correct equation is option 3) ? x 7 = 42.
Given that, Jordan has to solve this division problem: 42 divided by 7 = ?
In this case, Jordan needs to find the value of the missing factor, which represents how many times 7 can be multiplied to get 42.
Therefore, he can use the equation:
? x 7 = 42
This equation represents the inverse operation of division, which is multiplication.
When we know one factor (7) and the product (42), we can use multiplication to find the missing factor (the quotient).
By solving for the missing factor, he will find the correct answer to the division problem:
The missing factor = 42 / 7 = 6
So, the correct equation is option 3) ? x 7 = 42.

A cage has canaries and parakeets in the ratio 4:7. another cage has cockatiels and parakeets in the ratio 5:8. are the ratios of birds in the two cages equivalent?
Answers
Answer: No
Step-by-step explanation:
think of 4:7 as a fraction. that would be 4/7 right? so compare that to 5:8 as a fraction- 5/8. Are these fractions the same? the answer is no.
Answer: No.
Step-by-step explanation: In this situation, you should be able to multiply the lesser ratio by a certain number and it should be equivalent with the bigger one.
Example:
1:1
2:2
For this example, you would want to multiply 1:1 by Q. Q will be our variable here. So, 1 times q equals 2. Q would be equivalent to 2, now multiply both the 1's in 1:1.
The two ratios also don't hold the same types of birds, so it cannot be equivalent whatsoever.

Banana Cupcakes
makes 10 cupcakes
1 cup granulated sugar
cup vegetable oil
1 large egg
4 tablespoons sour cream
2 medium-sized ripe bananas, mashed
1 cups all-purpose flour
1 teaspoon baking soda
teaspoon salt
1 teaspoon vanilla extract
pinch of nutmeg
You will use the recipe above to answer the following questions:
This recipe serves 10, but you need to serve 30. What number will you need to multiply the amount of each ingredient by to adjust the recipe? How did you determine this number?
How much vegetable oil do you need for 30 cupcakes?
How much flour do you need for 30 cupcakes?
What is the difference in the amount of vanilla extract you would need for 30 cupcakes?
What is the difference in the amount of salt you would need for 30 cupcakes?
In the real world, even though you make adjustments to a recipe to accommodate the number of people you need to serve, you sometimes round the amount of an ingredient instead of using an exact amount. Which ingredient would it make more sense to round rather than coming up with the exact amount? Why?
Answers
Answer: Hey give me 1 hour and ill answer it I'm doing odessyware rn so Ill get back to you later appreciate yo patients.
Step-by-step explanation:
Then, if we want to make 30 servings, we need to use that recipe 3 times. (because x*10 = 30, then x = 30/10 = 3)
This would be equivalent to multiply each ingredient by 3.
for 30 cupcakes we need:
3 cups of vegetable oil.
3 cups of all-purpose flour
(because for each one of these ingredients we needed only 1 cup to make 10 cupcakes).
for 10 cupcakes we need 1 teaspoon of vanilla.
for 30 cupcakes we need 3 teaspoons of vanilla, the difference is 3 - 1 = 2.
So the difference is 2 teaspoons.
About which quantities we should round are those where we may have mixed numbers or big numbers.
For example, we have 4 tablespoons of sour cream for 10 servings, then for 30 servings we should have:
3*4 = 12 tablespoons.
We could round this down to 10 tablespoons.

A composite figure has a radius of 10 cm.
A circle with radius of 10 centimeters. One-quarter of the circle is cut out of the figure.
What is the area of this composite figure? Use 3.14 for Pi.
23.55 centimeters squared
78.5 centimeters squared
235.5 centimeters squared
314 centimeters squared
Answers
Answer:
C, 235.5 cm^2
Step-by-step explanation:
Formula for area of circle:
A = πr^2
Where π represents pi(3.14 or 22/7) and r represents the radius.
Plug in given value (10):
A = πr^2
A = 3.14(10)^2
A = 3.14(100)
A = 314
Now they say a quarter of this circle is cut out, which means we have to first find out what a quarter of this area is:
314/4
= 78.5
A quarter of this circle is 78.5, so let's subtract this from the total area (314):
314 - 78.5
= 235.5 cm^2
The area is 235.5 centimeters squared.
If x and y vary directly and y is 6 when x is 8, find y when x is 12.
Answers
Answer:
If x and y vary directly and y is 6 when x is 8, y is 9 when x is 12.
Step-by-step explanation:
In the given problem, it is known that when x is 8, y is 6, so the constant of proportionality in this case is k = y/x = 6/8 = 3/4. This means that the relationship between x and y can be written as y = (3/4)x.
To find the value of y when x is 12, we can plug this value into the equation to get y = (3/4) * 12 = 9. Therefore, if x and y vary directly and y is 6 when x is 8, y is 9 when x is 12.

(1, 50) , m = 50
y - y1 = m(x -x1)
y - 50 = 50(x -1)
y - 50 = 50x - 50

The units and tens digits of one-two digit integer are the tens and units digits of another two- digit integer, respectively. If the product of the two integers is 4930, what is their sum?
Answers
Answer:
(10t + u)(10u + t) = 4,930
100tu + 10t^2 + 10u^2 + tu = 4,930
101tu + 10t^2 + 10u^2 = 4,930
10t^2 + (101u)t + (10u^2 - 4,930) = 0
(101u)^2 - 4(10)(10u^2 - 4,930)
= 10,201u^2 - 400u^2 + 197,200
= 9,801u^2 + 197,200
We see that u = 5 gives 442,225.
√442,225 = 665
(10t + 5)(50 + t) = 4,930
500t + 10t^2 + 250 + 5t = 4,930
10t^2 + 505t - 4,680 = 0
2t^2 + 101t - 936 = 0
t = (-101 + √(101^2 - 4(2)(-936)))/(2×2)
= (-101 + √17,689)/4
= (-101 + 133)/4 = 32/4 = 8
So the numbers are 58 and 85.
58 + 85 = 143

Answer:
Part A:
6 feet
Part B:
Around 9.17 feet
Part C:
Around 3 feet
Step-by-step explanation:
Part A:
The Pythagorean Theorem (which is a^2 + b^2 = c^2), is the simpilist way to solve this. a = 8; c = 10. so, the problem becomes (64 + b^2 = 100). Subtract 64 from both sides to get (b^2 = 36). Square root both sides to get (b = 6).
Part B:
Using the same method, but with different measurements:
(a^2 + b^2 = c^2)
(16 + b^2 = 100)
(b^2 = 84)
(b = 9.17)
Part C:
The difference of 9.17 and 6 is 3.17. Therefore, the closest foot is 3. Hope this helps! Have a great day! :)
