please help me out, i'm really bad at math
Answer:
Step-by-step explanation:
3. [tex]\frac{3}{16}=\frac{x}{12}[/tex]
36 = 16x
9 = 4x
x = [tex]\frac{9}{4}[/tex]
4. [tex]\frac{x}{120}=\frac{1}{24}[/tex]
x = [tex]\frac{120}{24}[/tex]
x = 5
5. [tex]\frac{a-2}{9}=\frac{2}{3}[/tex]
3a - 6 = 18
3a = 24
a = 8
6. [tex]\frac{b+4}{5}=\frac{7}{4}[/tex]
4b + 16 = 35
4b = 19
b = [tex]\frac{19}{4}[/tex]
7. [tex]\frac{3}{7}=\frac{c+4}{35}[/tex]
105 = 7c + 28
7c = 105 - 28
7c = 77
c = 11
8. [tex]\frac{2c}{11}=\frac{c-3}{4}[/tex]
8c = 11c - 33
11c - 8c = 33
3c = 33
c = 11
9. [tex]\frac{7}{k-2}=\frac{5}{8}[/tex]
56 = 5k - 10
5k = 66
k = [tex]\frac{66}{5}[/tex]
12. [tex]\frac{c+1}{c-2}=\frac{4}{7}[/tex]
7c + 7 = 4c - 8
7c - 4c = -15
3c = -15
c = -5
13. [tex]\frac{v}{4}= \frac{7}{8}[/tex]
v = [tex]\frac{7}{2}[/tex]
14. [tex]\frac{9}{14}=\frac{3}{n}[/tex]
9n = 42
n = [tex]\frac{42}{9}[/tex]
n = [tex]\frac{14}{3}[/tex]
15. [tex]\frac{b+13}{2}=\frac{-5b}{3}[/tex]
3b +39 = -10b
13b = -39
b = -3
16. [tex]\frac{3b}{b-4}=\frac{3}{7}[/tex]
21b = 3b - 12
21b - 3b = -12
18b = -12
b = -[tex]\frac{12}{18}[/tex]
b = [tex]-\frac{2}{3}[/tex]
17. [tex]\frac{x+2}{2x-6}=\frac{3}{8}[/tex]
8x + 16 = 6x - 18
8x - 6x = -18 - 16
2x = -34
x = -17

Health officials in Parsnipville are concerned about the recent outbreak of the flu. While scientists are working hard to find a vaccine, the town leaders are turning to you to predict how many people will be sick over time. They hope to find a vaccine in a week. Here are the facts: The epidemic started on Day 0 when Velma and Stanley returned from their exotic jungle vacation with symptoms of the flu. Each day, a sick person infects two additional people. The town of Parsnipville has 3800 citizens.
Answer:
4372 people would have been sick over time.
Step-by-step explanation:
Since the vaccine would be found in a week, then the over time is a week (7 days). Each day, a sick person infects two additional people.
Number of people infected by Velma can be predicted as follows:
Day 1 - 2, Day 2 - 6, Day 3 - 18, Day 4 - 54, Day 5 - 162, Day 6 - 486, Day 7 - 1458
Number of people infected by Velma = 1458 + 486 + 162 + 54 + 18 + 6 + 2
= 2186
Also, number of people infected by Stanley can be predicted as follows:
Day 1 - 2, Day 2 - 6, Day 3 - 18, Day 4 - 54, Day 5 - 162, Day 6 - 486, Day 7 - 1458
Number of people infected by Stanley = 1458 + 486 + 162 + 54 + 18 + 6 + 2
= 2186
Total number of people than can be infected over time = 2186 + 2186
= 4372
Therefore, the predictable number of infected people over time would be 4372. All citizens of Parsnipville would have been infected before the vaccine is available.

Explanation:
The

mile cab ride includes a basic charge as well as the cost for the distance covered.
For a

4.80
which means that :
The cost of

The solution is, : The figure shows a line tangent to the circle is, 4th figure.
What is a tangent?As we know that, a tangent can be mentioned as a line segment to a circle which intersect the circle at exactly one point and that point is a tangency point.
here, we have,
the given figures,
we have to find the line that is tangent to the circle.
we know that,
a tangent is a line segment to a circle which intersect the circle at exactly one point and that point is a tangency point.
And the radius from the center of the circle to the point of tangent is always perpendicular to the tangent line.
now, from this figures we get,
From this we conclude that, 4th figure is a right angled triangle that means the radius from the center of the circle to the point of tangent is always perpendicular to the tangent line.

A bakery sells a dozen bagels for $8.50 and a dozen donuts for $3.99. Write an expression for the
cost of buying b dozen bagels and d dozen donuts.
Answer:
Total cost = ($8.50b) + ($3.99d)
Step-by-step explanation:
In a bakery, the cost of a dozen bagels = $8.50
and the cost of a dozen donuts = $3.99
1 Dozen = 12 pieces
Let 'b' represents the number of bagels (in dozen) and d represents dozen donuts.
The expression that represents total cost of b dozen bagels and d dozen donuts would be :
