i passed grade 7 lol
The price of gallons as per number of gallons.
1 gallon to $1.50
30 gallons to $45.00
$1.00 to 2/3 gallon
Finding cost of gallons
Accoring to the question, the price of two gallons of vinegar is $3.00. A chef need fifteen gallons of vinegar to make pickles.
As we know the price of two gallons of vinegar, we can find out price for any amount of vinegar by applying cross multiplication method.
Let's find out price of different amounts of gallons
The cost of two gallons of vinegar = $3.00
So, the cost of one gallon of vinegar = $3.00/2 = $1.50.
we find out that cost of one gallon of vinegar is $1.50.
Let's find the cost of other amount of gallons.
The cost of four gallons = ?
we know the cost of one gallon is $1.50, so the cost of four gallons is $1.50 × 4 = $6.00
This is how we can find out cost of other amount of gallons by multiplying number of gallons by the price of one gallon.

10. A certain strain of bacteria occurs in all raw milk. Tests of uncontaminated raw milk conducted by the Health Department found that the bacteria count per milliliter is normally distributed with a mean of 3500 and standard deviation of 300. a) What is the probability of finding a bacteria count of between 3200 and 3400 in a milliliter of raw milk? b) What percentage of the uncontaminated raw milk has a bacteria count per milliliter between 3200 and 3400? c) For this normal distribution, what is the percentage of the area under the normal curve for a bacteria count per milliliter less than zero? As bacteria count cannot be less than 0, is this small enough to disregard when claiming that the bacteria count per milliliter is normally distributed? Explain your answer.
Answer:
a) 0.21078
b) 21.078%
Step-by-step explanation:
We solve using z score formula
z = (x-μ)/σ, where x is the raw score, μ is the population mean, and σ is the population standard deviation.
Mean of 3500 and standard deviation of 300.
a) What is the probability of finding a bacteria count of between 3200 and 3400 in a milliliter of raw milk?
For x = 3200
z = 3200 - 3500/300
z = -1
Probability value from Z-Table:
P(x = 3200) = 0.15866
For x = 3400
z = 3400 - 3500/300
z = -0.33333
Probability value from Z-Table:
P(x = 3400) = 0.36944
The probability of finding a bacteria count of between 3200 and 3400 in a milliliter of raw milk
P(x = 3400) - P(x = 3200)
= 0.36944 - 0.15866
= 0.21078
b) What percentage of the uncontaminated raw milk has a bacteria count per milliliter between 3200 and 3400?
We convert the answer in part a) to percentage
= 0.21078 × 100
= 21.078%
What formula do you use to measure the entire length of a diagonal?
Answer:
d² = l² + w² ,
Step-by-step explanation:
You can use the Pythagorean theorem to estimate the diagonal of a rectangle, which can be expressed with the following formula: d² = l² + w² , and now you should know how to find the diagonal of a rectangle explicit formula - just take a square root: d = √(l² + w²) .

Angle a and b are complementary. M angle a equal (5x +2) degrees. Find m angle b. Justify your reasoning. Will mark brainliest !!!!!!!!!!!!!!!!!!!!!!!!!
Answer:
∠b = 88 - 5x
Step-by-step explanation:
If a and b are complementary, then sum of two angles is 90
∠a + ∠b = 90
5x + 2 + ∠b = 90
∠b = 90 - 5x - 2
∠b = 88 - 5x
Katie has a coin collection she keeps 7 of the coing in the box which is only 14% of her entire collection. What is the total number of coins in katie's collection
Answer:
x= 50
Step-by-step explanation:
7/x = 14/100
14x = 700
x = 50
the reason behind my calculations were to get the same ratios and because they gave us percentage and the actual number, we can set them; 14 percent 14/100, however, the 7/x is because we don't know the 100 percent of the coins which is what we look for. Therefore, you cross multiply and get x.
