Mrs. Smith charges $30 per hour for tutoring
services plus a one time fee of $10 for supplies.
How many tutoring sessions can a student attend
if the parent will spend, at most, $2,500?
Answers
Answer:
62.5
Step-by-step explanation:
$30 per hour + one time fee of $10= 40$ in total.
[tex] \frac{2500}{40} = 62.5[/tex]
Answer:
83 hours of tutoring, I think.
Step-by-step explanation:
If there is a total of 2,500 dollars to spend, you have to subtract the 10 dollar fee from it first to get 2,490 dollars. Then, you divide that by 30 dollars to get the total amount of hours which is 83.
The half-life of a certain radioactive material is 83 hours. An initial amount of the material has a mass of 67 kg. Write an exponential function that models the decay of this material. Find how much radioactive material remains after 5 hours. Round the answer to the nearest thousandth.
Answers
Answer:
Initial amount of the material is 67 kgHal-life is 83 hoursThe required equation is:
m(x) = 67 * [tex](1/2)^{x/83}[/tex], where m- remaining amount of the radioactive material, x - number of hoursAfter 5 hours the material remains:
m(5) = 67 * [tex](1/2)^{5/83}[/tex] = 64.260 (rounded)Richie is solving the equation x^2 – 12x = 28 by completing the square. What number should he add to
both sides of the equation to complete the square? Pleaseee Help
Answers
Answer:
Richie should add the number 36 to both sides.

43 lbs of bananas cost $86. How many
lbs of bananas can you get with $100 ?
will get brainliest
Answers
Answer:
$200
Step-by-step explanation:
Hey There!
So first we want to find the price of each pound of banana
To do this we divide the cost by amount of bananas bought
86/43=2
so each pound of bananas cost $2
now we just multiply 2 and 100
2x100=200
so 100 pounds of bananas would cost $200
hope this helps :)
Answer:
50
Step-by-step explanation:
Calculate how much 1lbs of bananas cost by dividing 86 by 43. getting you 2. That means each lbs of bananas is $2. Then divide $100 by $2 getting you 50 because you have $100. So you can get 50lbs of bananas with $100.

Answer:
Step-by-step explanation:
the mid point formula is Midpoint = (x1+x2)/2 , (y1+y2)/2
I know that probably looks like a jumbled mess huh .. the formula
In words it's basically saying.. get the distance between the two points and take half of that
S = (10, -1) where it takes the form of (x1,y1)
T = (2, -7 ) where it takes the form of (x2,y2)
then midpoint = (10+2) / 2 , (-1+(-7)) /2 ]
midpoint = 12/2 , -8/2
midpoint = ( 6 , -4 )

The average newborn baby weighs 7.0 pounds, give or take 1 pound. The average newborn hippopotamus weighs 40 pounds, give or take 1 pound. Which statement is true about the percent error of each of the two newborns?
a. A newborn baby has a smaller percent error
b. A newborn hippopotamus has a smaller percent error
c. Both newborns have the same percent error
d. There is not enough information to decide
Answers
Answer:
B
Step-by-step explanation:
since the average newborn hippopotamus has a larger weight, if you give or take one pound, the percent error will not make as much of a difference as it would with the weight of an average newborn baby (7 pounds). therefore, a newborn hippopotamus has a smaller percent error.

X=15 than you just plug it in for each angle
Answer:
∠A = 60°
∠B = 42°
∠C = 78°
Step-by-step explanation:
∵ In a triangle, sum of all the three interior angles is 180°
∴ m∠A + m∠B + m∠C = 180°
∴ (4x)° + (3x - 3)° + (5x + 3)° = 180°
∴ (4x + 3x - 3 + 5x + 3)° = 180°
∴ (12x)° = 180°
∴ 12x = 180
∴ x = 180/12
∴ x = 15
∠A = (4x)° = (4× 15)° = 60°
∠B = (3x-3)° = (3× 15-3)° =(45-3)°= 42°
∠C = (5x+3)° = (5× 15 + 3)° =(75 + 3)°= 78°

What is a triangle?A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry.In Euclidean geometry, any three points, when non-collinear, determine a unique triangle and simultaneously, a unique planeGiven are two sides of a triangle as b = 7m and c = 10m.
The sum of two sides of a triangle is always greater than the third side. Mathematically -
a < {b + c}
a < {7 + 10}
a < 17
a ∈ [1, 16]
