it is either the second one or the last one
Answer:
For (a) the answer is 450, 50(9)=450 total blocks.
Step-by-step explanation:
For (c), you will have to use a scale of 1 to 5, so, 450(5)=2,250.
For (b), if the map is 21 square inches and you want to enlarge it to the size you want, you would have to take the total value of the original map and multiply it by whatever factor it has to be multiplied by.
Now finally for (d), I applied proportional reasoning by looking at the dimensions and adding them all together to get the area value, then comparing the area value to the enlarged figure or decreased figure.
(I did this quite a long while ago, I'm going based on my memory and math skills, sorry if I failed horrendously.)

Someone plz help me >_<
Answer: (x - 2) ^2 + (y - 6) ^2 = 25
Answer:
(x - 48)² + (y - 24)² = 64Step-by-step explanation:
From the graph we see that
The diameter of the circle is: d = 16 mmThen its radius is: r = 16 mm/ 2 = 8 mmThe center has x-coordinate: h = 40 + 8 = 48Y-coordinate: k = 32 - 8 = 24Use circle formula:
(x - h)² + (y - k)² = r²Substitute values to get required equation:
(x - 48)² + (y - 24)² = 8²(x - 48)² + (y - 24)² = 64Mike will roll two number cubes labeled 1 through 6. After each roll, he adds the two numbers showing and records the result. He will roll the cubes 500 times. About how many times can he expect a sum greater than 8?
Answer:
In 500 rolls he can expect to get this outcome about 27.77...%* 500 = 139 times.
Larry is 4 times as old as his niece. Four years ago he was 6 times as old
as his niece was then. Find each of their ages now
9514 1404 393
Answer:
Larry: 40niece: 10Step-by-step explanation:
Let n represent the current age of the niece. Then 4n is Larry's current age. 4 years ago, the relationship was ...
6(n -4) = 4n -4
6n -24 = 4n -4
2n = 20
n = 10
Larry is 40; his niece is 10.

Jacob, non Hispanic white male. 30 years old.
Probability that Jacob lives to be 30 years old.
Since the given probabilities are probabilities of dying, I think we simply subtract it from 1 to get the probability of living. We will use the probability of non Hispanic white male.

Mateo, a 31-year-old nonsmoker ($5.50), wants to purchase $100,000 in coverage for himself and $75,000 for his spouse, who is female, 30 years old, and does not smoke ($3.50). What will the insurance premium be?
A. $30.50
B. $32.50
C. $35.50
D. $36.00
Answer: B. $32.50
Step-by-step explanation:
The premiums listed in brackets are for every $25,000 of coverage.
Mateo wants a $100,000 coverage so we need to divide this by $25,000 to see how much more he will have to pay:
= 100,000 / 25,000
= 4
Mateo will have to pay 4 times the $5.50 for himself:
= 4 * 5.50
= $22.00
For his spouse who requires $75,000, he will have to pay:
= 75,000 / 25,000
= 3
= 3 * 3.50
= $10.50
Total Mateo is to pay for both his spouse and himself is:
= 22 + 10.5
= $32.50
Answer: %32.50
9 + 10 = 21

Which symbol correctly compares the fractions below?
1/8 ? 1/2
Answer:
< "less than sign"
Step-by-step explanation:
1/8 is 0.125 in decimal form.
1/2 is 0.5 in decimal form.
Therefore, 1/2 is greater than 1/8 so you would use the less than symbol (<) for a final answer of 1/8<1/3.

30 POINTS!!! Find the area of each shaded region to the nearest hundredth. Show ur work
Answer:
[tex] 25.74 \: {m}^{2} [/tex]
Step-by-step explanation:
For parallelogram:
Base (b) = 6 + 3 = 9 m
Height (h) = 6 m
For circle:
Diameter = 6 m
Radius (r) = 6/2 = 3 m
Area of shaded region = Area of parallelogram - Area of circle
[tex] = bh - \pi {r}^{2} \\ \\ = 9 \times 6 - 3.14 {(3)}^{2} \\ \\ = 54 - 28.26 \\ \\ = 25.74 \: {m}^{2} [/tex]

What is the constant?
What is the coefficient?
What is the variable?
What are the factors of 9x?
Answer:
the constant is 3 the coefficant is y and the varible is a and the factors of 9 are 18 and 27
Step-by-step explanation:
Answer:
The constant is 3
The coefficient is 12
The variables are both A and Y.
Disclaimer: I'm not sure about this next one, but I believe it's right.
9x factors are 3x, 1, and 9x.
If you wanted me to factor it, then it'd be something like 3x(3)
Step-by-step explanation:
A constant is a number that is by itself. Variables can't be constants. In this case, the only number that is by itself, that isn't a variable is 3. Therefore, 3 is the constant.
A coefficient is a number that accompanies the variable. Normally in a math equation, a variable is multiplied by a number. In this case, A is being multiplied by 12, so 12 is the coefficient.
The variable is the letter that represents any number. In this case, there are two variables, A and Y. They both represent numbers that can differ. So, A and Y are the variables.
The factors of 9x are 3x, 3, 1x, 1, 9x, and 9.
9 times 1x is 9x, 9x times 1 is also 9x.
3 times 3x is 9x, and 3x times 3 is again, 9x.

Ivan found the change in a scale factor. His work is shown below. What error did Ivan make?
Old length = 35 feet New length = 10 feet
StartFraction 10 divided by 5 over 35 divided by 5 EndFraction = StartFraction 2 over 7 EndFraction
Answer:
PLS give me brainliest likes and 5 stars
Step-by-step explanation:
Here
Ivan wrote the ratio incorrectly. The ratio should be written as the old length to the new length, so it should be 35
10
, which reduces to 7
2
. When going from larger to smaller dimensions, the change in the scale factor is a ratio that looks like an improper fraction, with a larger number in the numerator and a smaller number in the denominator.

Step-by-step explanation:
If the triangle and the rectangle have the same area, what is the value of n if m=6?
Answer:
n=3
Step-by-step explanation:
Triangle area: height*length*(1/2)
Rectangle area: width*length
Let's say x is the length, then our equation would be:
mx(1/2)=nx
we also know m is 6, so
6x(1/2)=nx
now we can solve for n
6x(1/2)=nx
3x=nx
3=n
n=3

A plane is going to fly 400 miles at a planned speed of 570 mph. The flight will have an average headwind of w miles per hour the entire time, meaning the plane is flying directly against the wind. The time T, in hours, of the flight is a function of the speed of the headwind w, in mph, and can be modeled by
T(w) = 400/570 - W
a) What does T(150) mean in this situation?
b) At what value of w does the graph have a vertical asymptote? Explain how you know and what this asymptote means in the situation.
Step-by-step explanation:
t(150) = 400/570-150
=400/420
=20/21
=.95238
You are driving to visit a friend in another state who lives 700 miles away. You are driving 65miles per hour and have already driven 375 miles. Write and solve an equation to find how much longer in hours you must drive to reach your destination.
Answer:
5 hours
Step-by-step explanation:
distance = rate x time
t = time
(700-375) = 65t
325 = 65t
325/65 = t
5 hours = t
Identify CD. Please help ASAP
Answer: CD=7
Step-by-step explanation: By the definition of congruence, AB=CD.
Substitute the given expressions for AB and CD.
x+5=2x+3
Subtract x from both sides.
5=x+3
Subtract 3 from both sides.
2=x
Substitute x=2 back into the expression for CD and simplify.
CD=2(2)+3=7
Therefore, CD=7.
