Answer:
12.5 has to be the number that was doubled.
Step-by-step explanation:
24+2x=49 is your equation
you subtract 24 from 49 you get 25
25 divided by 2 is 12.5 there for 12.5+12.5 is 25
25+24=49
Hope this helps!
what is the value of y in this equation. 3-4y=19
Steps to solve:
3 - 4y = 19
~Subtract 3 to both sides
-4y = 16
~Divide -4 to both sides
y = -4

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 :
Total cost = ($8.50b) + ($3.99d)
PLEASE HELP Which of the following diagrams shows a line that is tangent to the circle?
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.

She must pay $200 to rent a booth at the craft fair. The materials for each pendant cost $7.80, and she plans to sell each pendant for $13.50. To make a profit, she must make more money than she spends.
Answer:
Instructions are below.
Step-by-step explanation:
Giving the following information:
She must pay $200 to rent a booth at the craft fair. The materials for each pendant cost $7.80, and she plans to sell each pendant for $13.50.
We weren't provided with questions to answer. But, I will assume that we need to determine the number of units to be sold to break-even.
To calculate the break-even point in units and dollars, we need to use the following formulas:
Break-even point in units= fixed costs/ contribution margin per unit
Break-even point in units= 200 / (13.5 - 7.8)
Break-even point in units= 35 units
Break-even point (dollars)= fixed costs/ contribution margin ratio
Break-even point (dollars)= 200 / (5.7/13.5)
Break-even point (dollars)= $473.68
If you want to reach a certain profit:
Break-even point in units= (fixed costs + desired profit) / contribution margin per unit
Break-even point (dollars)= (fixed costs + desired profit) / contribution margin ratio

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.

Answer:
-20 feet
Step-by-step explanation:
If the fish are closser to the suface it will be closer to 0 on the number line.
A fish finder is an instrument on a boat that indicates that fish are located in a radius of -20 to 0.
Given that,
A fish finder is an instrument on a boat that indicates where fish are located. The range of the fishfinder is to be specified.
Range, it is the set of the values that come out to an outcome for certain mathematical operations.
What is a number line?A number line is defined as the number marked on the line calibrated into an equal number of units. For example -1, 0, 1, and so on.
Here,
The range usual range of the fishfinder is standardly 0 to -20 on the number line of the instrument, where the negative sign indicates the depth.
Thus, A fish finder is an instrument on a boat that indicates that fish are located in a radius of -20 to 0.
