Janet's recipe calls for 3 cups of flour for every 2 cups of sugar. How much sugar does
Janet need, when she uses 9 cups of flour?
a) 6 cups b) 2⁄3 cup c) 8 cups d) 5 cups
Answer:
a) 6 cups
Step-by-step explanation:
Use a ratio equation to solve:
3/2 = 9/x
Cross multiply to get:
3x = 18
Solve for x:
x = 6
Answer: a) 6 cups
Step-by-step explanation: The 3 cups to get to 9, is really double the amount, so if you double 3 then you double 2 and get 6. 3*2=6

Step-by-step explanation:
6 increased by 2 --> 6+2
difference of 4 and 2 --> 4-2
first part times the second part --> 6 + 2 (4-2)
times a number --> • x
put it all together --> (6+2)(4-2) • x or 16x

In the table, the relation (x, y) is not a function if the missing value of xis
Reset
Next
Answer:
The missing value of x is 3
Step-by-step explanation:
Given Table:
x y
3 10
__ 20
The relation of x and y (x,y) is not a function.
Relation is function if it is one-to-one.
One-to-one means to different value of x to get different value of y.
If function is not a function then one value of x to get two different value of y.
For first value of x=3, y=10
For which value of x= ? , y=20
x must be 3
x=3 to get y=20
The missing value of x is 3 because same of x we get two different value of y.

The approximate number of Calories, C, that an animal needs each day is given by C = 72m^3/4, where m is the animal's mass in kilograms. Find the number of

Calories
someone plss helpp!?!!
Answer:
[tex]\huge\boxed{576 \ \text{calories}}[/tex]
Step-by-step explanation:
In order to find the number of calories that an [tex]m[/tex] kg animal weighs, we can substitute what we need inside the formula given, [tex]72m^{\frac{3}{4}}[/tex]. Since we want to find how much a 16 kg dog needs to eat, we substitute 16 in as m.
[tex]72\cdot 16^{\frac{3}{4}}[/tex]
BPEMDAS tells us that the order of solving equations is
Brackets
Parantheses
Exponents
Multiplication/Division
Addition/Subtraction
Looking at this order, we need to do [tex]16^{\frac{3}{4}}[/tex], then multiply by 72.
When we have a number to a fraction power, we need to note that
It's the same as taking the denominator root of the base to the numerator powerTherefore, our expression will be [tex]\sqrt[4]{16^3}[/tex].
[tex]16^3 = 4096[/tex] [tex]\sqrt[4]{4096} = 8[/tex]Now that we have this much, we need to multiply it by 72 as our formula read [tex]72m^{\frac{3}{4}}[/tex].
[tex]72 \cdot 8=576[/tex]Therefore, an animal weighing 16 kg needs to consume 576 calories.
Hope this helped!

A mailbox that is 4 1/2 feet tall casts a shadow that is 6 feet long. At the same time, a nearby ferris wheel casts a shadow 84 feet long. Find the height of the ferris wheel.
60 feet
Answer: 63 ft
Step-by-step explanation:
We can think of the shadow and height of objects as the catheti of a triangle rectangle.
We also know the relationship:
Tan(θ) = (opposite cathetus)/(adjacent cathetus)
if we define:
Tan(θ) = k (a real number, such that will be the same number for every object, because it depends on the angle θ that will depend on the position of the sun)
opposite cathetis = heigt.
adjacent cathetus = length of the shadow.
Then we have:
k = height/length of the shadow.
For the mailbox, we know that the height is (4 + 1/2) ft and the shadow is 6ft long, then we have the equation:
k = (4 + 1/2)ft/6ft = 0.75
Then for the ferris wheel we know:
shadow length = 84ft
we can write the same equation as above:
k = 0.75 = height/84ft
0.75*84ft = height = 63ft
The ferris wheel is 63 ft high.
Answer:
63 feet

A Government company claims that an average light bulb lasts 270 days. A researcher randomly selects 18 bulbs for testing. The sampled bulbs last an average of 260 days, with a standard deviation of 90 days. If the CEO's claim were true, what is the probability that 18 randomly selected bulbs would have an average life of no more than 260 days
Answer:
31.92% probability that 18 randomly selected bulbs would have an average life of no more than 260 days
Step-by-step explanation:
To solve this question, we need to understand the normal probability distribution and the central limit theorem.
Normal probability distribution
When the distribution is normal, we use the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
Central Limit Theorem
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean [tex]\mu = p[/tex] and standard deviation [tex]s = \sqrt{\frac{p(1-p)}{n}}[/tex]
In this question, we have that:
[tex]\mu = 270, \sigma = 90, n = 18, s = \frac{90}{\sqrt{18}} = 21.2[/tex]
What is the probability that 18 randomly selected bulbs would have an average life of no more than 260 days?
This is the pvalue of Z when [tex]X = 260[/tex]. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
By the Central Limit Theorem
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{260 - 270}{21.2}[/tex]
[tex]Z = -0.47[/tex]
[tex]Z = -0.47[/tex] has a pvalue of 0.3192.
31.92% probability that 18 randomly selected bulbs would have an average life of no more than 260 days
The speed of light is 3 x 10 8 meters per second (m/s). What is the speed of light in miles per year (mi/yr)
Answer:
the speed of light in miles per year is 5.88 × 10^12 mi / year
Step-by-step explanation:
The computation of the speed of light in miles per year is shown below;
As we know that
1 m/sec = 1 ÷ 1609 mi/sec
3 ×10^8 m/sec = (3 × 10^8) ÷ (1609)
= (3 × 10^8 × 60 × 60 × 24 × 365) ÷ (1609)
= 5.88 × 10^12 mi / year
Hence, the speed of light in miles per year is 5.88 × 10^12 mi / year
