Answer:

Step-by-step explanation:
[tex] \frac{35x - 2 - 93}{2} = 7x + 5[/tex]
[tex] \frac{35x - 95}{2 } = 7x + 5[/tex]
[tex]17.5x - 47.5 = 7x + 5[/tex]
[tex]17.5x = 7x + 52.5[/tex]
[tex]10.5x = 52.5[/tex]
[tex]x = 5[/tex]
Plug 5 in for 7x+5.

A three-dimensional L-shaped figure is made of two rectangular prisms joined at a right angle. A horizontal rectangular prism has a length of eight inches, a width of two inches, and a height of two inches. A vertical rectangular prism connected at the right end of the other prism has a length of two inches, a width of two inches, and a height of eight inches. What is the total volume of the composite figure?
The total volume of the composite figure is 64 in³.
Volume of a rectangular prismThe volume of a rectangular prism, V = lwh where
l = length, w = width and h = heightVolume of horizontal rectangular prismSince horizontal rectangular prism has a length of eight inches, a width of two inches, and a height of two inches. So,
l = 8 in, w = 2 in and h = 2 in.So, its volume V' = lwh
= 8 in × 2 in × 2in
= 32in³
Volume of vertical rectangular prismSince the vertical rectangular prism connected at the right end of the other prism has a length of two inches, a width of two inches, and a height of eight inches. So,
l = 2 in, w = 2 in and h = 8 in.So, its volume V" = lwh
= 2 in × 2in × 8 in
= 32 in³
Volume of composite figureThe volume of the composite figure V"' = V' + V"
= 32 in³ + 32 in³
= 64 in³
So, the total volume of the composite figure is 64 in³.

Answer:
yes your formula is correct
Step-by-step explanation:
A basketball is thrown upward from a height of 6 feet at an initial speed of 15 feet per second. As the basketball travels, Earth's gravity slows it down.
The height of an object dropped from a height of 6 feet is given by h(t)=−16t2+6.
The distance in feet traveled by an object at a constant speed of 15 feet per second is given by d(t)=15t.
These two functions can be combined to build a new function, f, that models the height of the basketball as a function of time in t seconds.
Which choice shows how to combine h and d to build f
Answer: f(t)=h(t)+d(t)
f(t)=-16t^2+15t+6

The Halloways are taking a trip to Maine. Mr. Halloway knows that it is about 885 miles to their destination in Maine from their home in Ohio. He knows the average speed along his route will be 65 miles per hour. How many hours is the drive?
Answer:
Number of hours= 13.61 hours
Step-by-step explanation:
Giving the following information:
Mr. Halloway knows that it is about 885 miles to their destination.
Average speed= 65 miles per hour
To calculate the number of hours to be drive, we need to use the following formula:
Number of hours= total miles / miles per hour
Number of hours= 885/65
Number of hours= 13.61 hours

The two column proof of the fact that △ACO is congruent to △BCO is; SSS Congruence Theorem
How to write the two column proof?
We are given that;
angle AOB is a central angle of circle O
angle ACB is a circumscribed angle of circle O.
Now, AO ≅ BO. The reason is because all radii of the same circle are congruent.
We are told that; AC ≅ BC. The reason is because tangents to a circle that intersect each other are congruent.
Using the reflexive property, we see that side CO is congruent to side CO.
Finally, we can conclude that △ACO is congruent to △BCO by the SSS congruence theorem.

Answer:
a part of the population that represents the entire population
Step-by-step explanation:
A sample simply refers to a smaller group of observation usually drawn from a larger group or a collection of the total possible observation that fits a particular or specific characteristic(population). This smaller group or subset of observation is usually chosen to be representative of the larger group of population. Representative Samples are usually obtained by drawing at random from the population and are very important where using the entire population for a study seems impossible or very expensive or intensive.

Choose the correct simplification of the expression a^9 multiplied by b^10/a^2 multiplied by b^7
A^11b^17
1/a^11b^17
1/a^7b^3
A^7b^3
Answer:
a^7 b^3
Step-by-step explanation:
The question can be interpreted as
[(a^9)( b ^10)] / [(a^2 )×( b ^7)]
Then we can bring the denominator up, which means the power on the denominator will become (-ve) once it comes to the numerator side. Then we have
a^(9-2) × b^(10-7)
We can simplify by performing substraction on the power
= a^7 b^3

A grab-bag contains 30 packages worth $.65 each, 10 packages $.60 cents each, and 15 packages worth $.30 each. What is the expected value if you have to pay $.50 to pick one package at random?
Answer:
Expected value of package = $0.04 (Approx.)
Step-by-step explanation:
Given:
30 packages at $0.65 each
10 packages at $0.60 each
15 packages at 0.30 each
Pick up price for random one = $0.50
Find:
Expected value of package
Computation:
Total cost of 30 package = 30 x 0.65
Total cost of 30 package = $19.5
Total cost of 10 package = 10 x 0.60
Total cost of 10 package = $6
Total cost of 15 package = 15 x 0.30
Total cost of 15 package = $4.5
Total cost = 19.5 + 6 + 4.5
Total cost = $30
Cost of random package = 30 / [30+10+15]
Cost of random package = $0.54
Expected value of package = 0.54 - 0.50
Expected value of package = $0.04 (Approx.)

Emma bought two televisions at 2500.00 each.One got slightly damaged during transportation.He sold the undamaged one at 3000.00 and sold the damaged one at 2200.00.Calculate the profit made by Emma
Answer:
200.00
Step-by-step explanation:
Cost of 2 television at 2,500.00 each = 2 × 2,500.00
= 5000.00
Cost of 2 television = 5,000.00
Selling price of the undamaged TV = 3000.00
Selling price of the damaged TV = 2200.00
Total selling price = 3000.00 + 2200.00
= 5,200.00
Total selling price = 5,200.00
Profits = selling price - cost price
= 5,200.00 - 5,000.00
= 200.00
Profits = 200.00
