Answer: 3 gallons of water would be mixed with 1/2 gallon of the chemical

Step-by-step explanation:

If the mix ratio for certain chemical is 1:6 when it is mixed with water. This means that for every 1 gallon of the chemical, 6 gallons of water is required.

Therefore, the number of gallons of water that would be mixed with 1/2 gallon of the chemical becomes

1/2 × 6 = 3 gallons of water.

you roll a number cube twice. find p(even, then not 2). Write the probability as a fraction in simplest form.
aksik [14]
For the first roll, you expect that you would get an even number. Since there are six sides of a die, then there are 3 ways to get an even number which are numbers 2, 4 and 6. So the probability of an even number is 3/6 or 1/2.
Next for the second roll, you expect that you should not get a number 2. There are 5 ways occurring which are 1, 3, 4, 5, 6. So the probability for this is 5/6.
Multiply the two probabilities because both probabilities will occur for this event.
P(even, then not 2) = (1/2)(5/6) = 5/12

A circle with radius of \greenD{4\,\text{cm}}4cmstart color #1fab54, 4, start text, c, m, end text, end color #1fab54 sits insid
mario62 [17]

Answer:

The area of the shaded region is   329.87\ cm^2

Step-by-step explanation:

<u><em>The correct question is</em></u>

A circle with radius of 4cm sits inside a circle with a radius of 11cm. What is the area of the shaded region?

The shaded region is the area outside the smaller circle and inside the larger circle

we know that

To find out the shaded region subtract the area of the smaller circle from the area of the larger circle

so

A=\pi r_a^{2} -\pi r_b^{2}

simplify

A=\pi (r_a^{2} -r_b^{2})

where

r_a is the radius of the larger circle

r_b is the radius of the smaller circle

we have

r_a=11\ cm\\r_b=4\ cm

substitute

A=\pi (11^{2} -4^{2})

A=\pi (105)\ cm^2

assume

\pi=3.1416

substitute

A=(3.1416)(105)=329.87\ cm^2

Michaela’s class used a spinner that has 6 spaces of equal area in which the arrow can land. The areas are numbered 1, 2, 3, 4,
diamong [38]

The number of times the spinner landed on a space numbered greater than 4 = 167

Step-by-step explanation:

Step 1 :

Given,

Number of equal area spaces in the spinner = 6

Number of times the spinner was spun = 500

We need to find  the number of times the spinner landed on a space numbered greater than 4

Step 2 :

Total number of outcome = 6

Favorable outcomes are = Numbers greater than 4 = 5,6

Total number of favorable outcome = 2

Therefore Probability that the spinner will land on a number that is greater than 4 is \frac{2}{6} = \frac{1}{3}

The number of times that the spinner landed on a space numbered greater than 4 = 500 × \frac{1}{3} = 166.67 = 167 (rounded off to the nearest integer)

Step 3 :

Answer :

The number of times the spinner landed on a space numbered greater than 4 = 167

Which is an x-intercept of the continuous function in the table?
Ad libitum [116K]

Answer:

B. (3, 0)

Step-by-step explanation:

The x-intercept is the point where the graph of the function meets the x-axis.

At x-intercept, y=0 or f(x)=0

So look through the table and find where f(x)=0.

From the table, f(x)=0 at x=3.

We write this as an ordered pair.

Therefore the x-intercept is (3,0)

The correct choice is B.

the united states has 12,383 miles of coastline.if 0.8% of the coastline is located in georgia,about how many miles of coastline
Sever21 [200]

Answer:

825.5 miles of coastline

Step-by-step explanation:

The United States has 12383 miles of coastline.

0.8% of the coastline is in Georgia

Total number of coastline in Georgia will be

0.8% /100% x 12383

0.0667 x 12383

825.5

So there are 825.5 miles of coastline Georgia
