The surface area to this problem would be 2352yd^2. mainly because I saw 4 rectangles I needed to find the area of and 2 small blue squares also. to get the are of the two small squares youd have to multiply 14x14, which is 196, then times 192x2=392. but to get the rectangles you would have to multiply 35x14=1960. after that I added 1960+392+2352yds.

The surface area is the area on the surface of the shape (I suck at describing things ). To find that, you have to find the area of each shape and add them all together. I hoped this helps

The result of our calculations about the rate and time are:

r=d/t

200000m/hr

200km/hr

km/hr

Rate can be regarded as the given object with respect to time.

falcon flies= 800,000 meters

t= 4 hours

We were given the formula as (d = rt)

d= distance

r = rate

t = time

We can make our calculations as:

part a:

r=d/t

part b:

falcon's rate in meters per hour = 800,000 meters / 4 hours = 200000m/hr

part c:

falcon's rate in kilometers per hour=(200000m/hr *(1/1000)=200km/hr

part d:

km/hr

IQ scores are normally distributed with a mean of 100 and a standard deviation of 15.

jekas [21]

Using the normal distribution, it is found that 1851 people would have an IQ less than 115.

<h3>Normal Probability Distribution</h3>

The z-score of a measure X of a normally distributed variable with mean $\mu$ and standard deviation $\sigma$ is given by:

$Z = \frac{X - \mu}{\sigma}$

The z-score measures how many standard deviations the measure is above or below the mean.

Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.

The mean and the standard deviation are given, respectively, by:

$\mu = 100, \sigma = 15$

The proportion of IQ scores less than 115 is the <u>p-value of Z when X = 115</u>, hence:

$Z = \frac{X - \mu}{\sigma}$

$Z = \frac{115 - 100}{15}$

Z = 1

Z = 1 has a p-value of 0.8413.

Out of 2200 people:

0.8413 x 2200 = 1851.

A recipe requires 1/3 cup of oil for every 2/5 cup of water. How much oil (in cups) is needed per cup of water?

igor_vitrenko [27]

3/8 cups of oil

Step by step explanation:

Given : A recipe requires 1/4 cup of oil for every 2/3 cup of water.

To Find: How much oil (in cups) is needed per cup of water?

Solution:

Oil required by 2/3 cup of water = 1/4

Oil required by 1 cup of water = 1/4
= 2/3
= 3/8
Hence cups of oil is needed for per cup of water.

6x - 9 = 15 linear equations

finlep [7]

Answer:

x = 4

Step-by-step explanation:

6x - 9 = 15

6x - 9 + 9 = 15 + 9

6x = 24

6x / 6 = 24 / 6

x = 4
