Step-by-step explanation:
adam prepares a meal of shrimp and brown rice. it must contain exactly 6 g of fat and 10 mg of iron. each 5oz serving of shrimp contains 2 g fat and 5 mg iron. each 1 cup of brown rice contains 6 g fat and 7 mg iron. how many servings of shrimp and brown rice should be in the meal?
Answer:
Adam needs 9/8 of a 5oz serving of shrimps (which equals to 5.625 oz) and 5/8 of a cup of brown rice (which is around 10 tablespoons).
Explanation:
You are given:
every serving of shrimp contains 2g of fat and 5mg of iron;
every serving of rice contains 6g of fat and 7mg of iron;
each meal should have 6g of total fat and 10mg of total iron.
You need to set a system of equation: let's call
s = quantity of shrimps
r = quantity of rice
The equation for the total fat will be: the quantity of fat in the serving of shrimps plus the quantity of fat in the serving of rice must be equal to 6g
2s + 6r = 6 (1)
Similarily:
the quantity of iron in the serving of shrimps plus the quantity of iron in the serving of rice must be equal to 10g
5s + 7r = 10 (2)
In order to solve the system, solve for s in equation (1):
s = (6-6r)/2 = 3 - 3r (3)
Substitute in equation (2):
5(3 - 3r) + 7r = 10
and solve for r:
15 - 15r + 7r = 10
8r = 5
r = 5/8
Substitute the value of r in equation (3):
s = 3 - 3×5/8 = 9/8
Therefore Adam would need 9/8 of a 5oz serving of shrimps and 5/8 of a 1 cup of brown rice for each meal.

10(5 - n) - 1 = 29
n = ?
Help!
n = 2
distribute and simplify left side of equation
50 - 10n - 1 = 29
49 - 10n = 29 ( subtract 49 from both sides )
- 10n = 29 - 49 = - 20
n = [tex]\frac{-20}{-10}[/tex] = 2
To get rid of the parantheses we must multiply 10 by anything inside the parantheses.
10(5-n)-1=29
50-10n-1=29
Combine like terms
50-10n-1=29
49-10n=29
Subtract 49 from both sides
49-10n=29
-10n=-20
Divide both sides by -10
-10n/-10=-20/-10
n=2
Our final answer is 2

what is 34% of 510.
Tracereed,
In order to solve this question you have to divide 34 by 100 then divide that by 510.
[tex]100 \div 34[/tex][tex]510 \div 34 = 2.9411764705882[/tex][tex]15 \div 100 =173.4 [/tex][tex]173.4[/tex]Therefore "173.4 is 34% of 510!"
Hope this helps!
To find 34% of 510, first write 34% as a decimal by moving the decimal point two places to the left to get .34.
Next, the word "of" means multiply, so we are going to multiply.
(.34) (510) = 173.4
Therefore, 34% of 510 is 173.4.

Three different car are available to take five women and a man on a particular journey. In how many different ways can the six people be allocated to the car so that the man is alone.
To find the number of ways six people can be allocated to three different cars with the man alone, we consider the man's three choices and then partition the five women into the remaining two cars in all possible ways, then multiply by the man's choices.
Explanation:The question asks for the number of different ways six people can be allocated to three different cars, ensuring the man is alone. Since there are three cars, the man has three choices of cars to be alone in. After the man has chosen his car, we have five women and two remaining cars. The five women can be distributed in these cars in a 5-partition of two numbers, which means the number of ways we can divide five into two groups without considering order.
The possible partitions for the five women are (3,2), (4,1), and (5,0). For each partition, there are combinations of woman that can occupy the cars. For example, for partition (3,2), we have 5 choose 3 ways to choose which three women are in the first car and the remaining two automatically go to the second car. We repeat this process for each partition. Finally, we must multiply the number of ways for each partition by the three initial choices the man had to get the total number of combinations.

In the diagram abc=adb=90, ad=p and dc=q. Use similar triangles to show that x2=pz
plzz anyoneee
Answer:
By comparing the ratios of sides in similar triangles ΔABC and ΔADB,we can say that [tex]x^{2} =pz[/tex]
Step-by-step explanation:
Given that ∠ABC=∠ADC, AD=p and DC=q.
Let us take compare Δ ABC and Δ ADB in the attached file , ∠A is common in both triangles
and given ∠ABC=∠ADB=90°
Hence using AA postulate, ΔABC ≈ ΔADB.
Now we will equate respective side ratios in both triangles.
[tex]\frac{AB}{AC}= \frac{AD}{AB}=\frac{BD}{BC}[/tex]
Since we don't know BD , BC let us take first equality and plugin the variables given in respective sides.
[tex]\frac{x}{z}= \frac{p}{x}[/tex]
Cross multiply
[tex]x^{2}=pz[/tex]
Hence proved.

fred has two types of peanut butter,three types of jelly, and one type of bread. how many different peanut butter and jelly sandwich can he make?
Answer:
6
Step-by-step explanation:
fred has 2 peanut butter and 3 jelly
type 1 peanut butter can go with all three types of jelly = 3 pb&js where ther is one constant peanutbutter and 3 different jellys
type 2 peanut butter can go with all three jellies = 3 pb&js where there is one constant peanutbutter and 3 different jellies
3+3=6
there are 6 peanut butter and jelly sandwhiches he could make.
you can also just multiply the numbers (2x3=6)
Final answer:
Fred can make 6 different peanut butter and jelly sandwiches by multiplying the number of peanut butter types by the number of jelly types (2 types of peanut butter × 3 types of jelly). The type of bread does not affect the count as there's only one type.
Explanation:
To determine how many different peanut butter and jelly sandwiches Fred can make, we need to consider all possible combinations of peanut butter, jelly, and bread. Since Fred has two types of peanut butter, three types of jelly, and one type of bread, the number of different sandwich combinations can be calculated using the Counting Principle. This principle states that if there are n ways to do one thing, and m ways to do another, then there are n × m ways to do both.
In Fred's case, for every type of peanut butter, he can choose from three different types of jelly. So, for two types of peanut butter, we have:
2 types of peanut butter × 3 types of jelly = 6 combinations
Since there's only one type of bread, it doesn't change the number of combinations.
Therefore, Fred can make 6 different peanut butter and jelly sandwiches.

Mai has 40 tens. Write how many hundreds. Write the number.
The number is 400.
To find out how many hundreds Mai has, let's understand that each ten is equal to 10. So, if Mai has 40 tens, we can calculate how many ones that is in total:
40 tens * 10 = 400 ones
Now, since there are 100 ones in one hundred, we divide the total number of ones by 100 to find out how many hundreds Mai has:
400 ones / 100 = 4 hundreds
So, Mai has 4 hundreds.
Now, let's write the number:
If Mai has 4 hundreds, it means the digit in the hundreds place is 4. Since she has no tens, the digit in the tens place is 0. And since she has no ones, the digit in the ones place is 0.
