About `3. 2 x 10^{8}` people live in the United States.
About `3. 9 x 10^{7}` people live in Canada.
And about `1. 1 x 10^{8}` people live in Mexico.
About how many people live in all three countries altogether?
Answer:
About 4.69 x 10^8 people live in all three countries altogether
Step-by-step explanation:
3.9 x 10^7 is .39 x 10^8
now you can make x 10^8 into y
3.2y + .39y + 1.1y =
4.69y
make y into x 10^8 again
4.69 x 10^8

For a given input value a, the function f outputs a value b to satisfy the following equation.
-3a+6b=a+4b
Write a formula for f(a) in terms of a
Answer:
ok
Step-by-step explanation:
-3a + 6b = a + 4b
we move both values to the same side
6b – 4b = a + 3a
subtracting 6 from 4 gives us 4, and a 1 plus 3 gives us 4
2b = 4a
divide 4 on both sides to solve for a and to get a by itself.
1/2=a
please mark as brainlest.
Hey there!
Let's solve for a.
[tex] \fbox{−3a+6b=a+4b}[/tex]
Step 1: Add -a to both sides.
[tex] \fbox{−3a+6b+−a=a+4b+−a}[/tex]
[tex] \fbox{−4a+6b=4b}[/tex]
Step 2: Add -6b to both sides.
[tex] \fbox{−4a+6b+−6b=4b+−6b}[/tex]
[tex] \fbox{−4a=−2b}[/tex]
Step 3: Divide both sides by -4.
[tex] \fbox{−4a/−4 = −2b/−4}[/tex]
[tex] \fbox{a= 1/2b}[/tex]
Answer:
[tex] \fbox{a= 1/2b}[/tex]

DVDs are on sale for $28 each. Felipe writes the expression 5 × 28 to find the cost in dollars of buying 5 DVDs. How can you rewrite Felipe's expression using the Distributive Property? Felipe's expression can also be written as (5 × 20) + (5 × )
Answer:
Felipe's expression using the Distributive Property can be written as
5 × 28 = 5( 20 + 8)
5 × 28 = (5 × 20) + (5 × 8)
Step-by-step explanation:
Distributive property states that:
a( b + c) = ab + ac
We are told in the question that:
DVDs are on sale for $28 each. Felipe writes the expression 5 × 28 to find the cost in dollars of buying 5 DVDs.
Therefore:
Felipe's expression using the Distributive Property can be written as:
5 × 28 = 5( 20 + 8)
5 × 28 = (5 × 20) + (5 × 8)
Thirty percent of what number is 13.5?
Answer:
Well we can take this word for word into an expression
thirty percent of which is basically
0.3 *
We have an unknown number (what number) lets make that unknown number x
0.3 * x
And we want to know what is 13.5 which basically means equal 13.5
0.3 * x = 13.5
We solve for x
Solve from here.
I’m gonna multiply 10 on both sides
3 * x = 135
Now solve
x = 45

An open circle is at 8. Everything to the left of the circle is shaded. A number line going from 3 to 13. An open circle is at 8. Everything to the right of the circle is shaded.
Answer:
An open circle at 32 and everything to the right of the circle is shaded.
Step-by-step explanation:
[tex]-\dfrac12p < -16[/tex]
Divide both sides by -1 (remembering to reverse the sign):
[tex]\implies \dfrac12p > 16[/tex]

A burrito restaurant used the given table to keep track of the numbers of different types of burritos that were sold and the kinds of beans that people requested. consider the following events: a. the burrito is a chicken burrito. b. the burrito is a carne asada burrito. c. the customer requested black beans. d. the customer requested pinto beans. a 6-column table has 4 rows. the first column has entries black beans, pinto beans, no beans, total. the second column is labeled fish with entries 2, 10, 36, 48. the third column is labeled carne asada with entries 5, 24, 51, 80. the fourth column is labeled vegetarian with entries 1, 8, 20, 29. the fifth column is labeled total with entries 45, 72, 123, 240. which two events are independent? a and c a and d b and c b and d
The two events which are independent are the carne-asada burrito (B) and the customer requested pinto beans (D).
What is the independent events?Independent events are those events whose occurrences do not depend on the other events.
A burrito restaurant used the given table to keep track of the numbers of different types of burritos that were sold and the kinds of beans that people requested.
Consider the following events:
A. The burrito is a chicken burrito.B. The burrito is a carne asada burrito. C. The customer requested black beans. D. The customer requested pinto beans.The probability of event A is,
[tex]P(A)=\dfrac{83}{240}[/tex]
The probability of event B is,
[tex]P(B)=\dfrac{80}{240}=\dfrac{1}{3}[/tex]
The probability of event C is,
[tex]P(C)=\dfrac{45}{240}=\dfrac{3}{16}[/tex]
The probability of event D is,
[tex]P(A)=\dfrac{72}{240}=\dfrac{3}{10}[/tex]
If the probability of an event is calculated given that the other is happened, only the probability of event B and D we get such that,
[tex]P(B\cap D)=P(B).P(D)\\\dfrac{24}{240}=\dfrac{1}{3}\times \dfrac{3}{10}\\\dfrac{1}{10}=\dfrac{1}{10}[/tex]
Thus, the two events which are independent are the carne-asada burrito (B) and the customer requested pinto beans (D).

Circle A has a circumference of 25 centimeters. Circle B's diameter is 3 times as long as circle A’s diameter. What is the circumference of circle B?
- And don’t say 10 because it’s wrong
Answer: 74.98cm
Step-by-step explanation:
Step 1: Find out radius of Circle A. [We use circumference of circle A to find its radius].
Circumference of circle A = 2πr; where r is radius.
To better viewing we change sides, we get:
2πr = Circumference of circle A
2πr = 25
r = [tex]\frac{25}{2\pi }[/tex]
r = [tex]\frac{25}{3.14}[/tex]
r ≈ 3.98
Step 2: Calculate the diameter of circle A.
diameter of circle A = 2r = 2(3.98) = 7.96
Step 3: Finding diameter of circle B.
diameter of circle B = 3(diameter of circle A) = 3(7.96) = 23.88
Step 4: Converted diameter of circle B to r.
diameter of circle B = 2r
23.88 = 2r
divided 2 from both sides, we get:
11.94 = r
Step 5: Substitute radius of circle B into the circumference formula, where C = 2πr.
C = 2πr
C = 2(3.14)(11.94)
C ≈ 74.98

A balance scale is perfectly balanced with 2 cans of soda on one side and 1 can of soda and 8 ounces of sand on the other . How much does each can of soda weigh?
The balance scale is perfectly balanced when it sits perfectly
The weight of each can of soda is 8 ounces
How to determine the weight of the soda canRepresent the weight of the can with x.
On the first side, where there are 2 cans of soda.
The weight is 2x
On the other side, where there is 1 can of soda and 8 ounces of sand
The weight is x + 8
Since the balance scale is perfectly balanced, then we have the following equation
2x = x + 8
Subtract x from both sides
x = 8
Hence, the weight of each can of soda is 8 ounces

Use the proportion to solve for the unknown base measure of the enlarged trapezoid. 1.Set up the proportion: StartFraction 2 over 3.25 EndFraction = StartFraction x over 6.5 EndFraction 2.Use cross products: 2(6.5) = 3.25(x) 3.Simplify: 13 = 3.25x 4.Divide both sides by 3.25: The missing base measure of the enlarged trapezoid is cm.
Answer:
The missing base measure of the enlarged trapezoid is 4cm.
Step-by-step explanation:
Step 1:
2 / 3.25 = x / 6.5
Step 2:
Cross product
2 * 6.5 = 3.25 * x
