Sam has three identical tennis balls with a diameter of 2.7 inches. Determine the volume of all three tennis balls?
Answer:
They are 30.93 in³ altogether.
Step-by-step explanation: V = 4/3 π r³
r = 2.7/2 = 1.35
π x 1.35 x 1.35 x 4/3 = 10.31 in³
10.31 x 3 = 30.93
solve for 7x2 = 10x
Answer:
x = 0, x = [tex]\frac{10}{7}[/tex]
Step-by-step explanation:
Given
7x² = 10x ( subtract 10x from both sides )
7x² - 10x = 0 ← factor out x from each term
x(7x - 10) = 0
Equate each factor to zero and solve for x
x = 0
7x - 10 = 0 ⇒ 7x = 10 ⇒ x = [tex]\frac{10}{7}[/tex]
Answer:
x = 1.4
Step-by-step explanation:
1. Simplify the left side so you get 14 = 10x
2. Divide the whole equation by 10
3. x = 1.4

The company's profit in the year 2003 is $3.1 million
What is profit?Profit is stated as the amount of revenue generated after deduction of all the liabilities. Profit is the money you have left after paying for business expenses. There are three main types of profit: gross profit, operating and net profit.
Given that,
in the year 2000 profit = $2.2 million
Each year increase in profit = 13% =0.13
Total number of year = 2003-2000=3 years
Profit is denoted by
profit = initial profit ( 1 + each year increase)^years
Substituting the values we get
profit=2.2( 1 + 0.13)³
=2.2( 1.13)³
=3.174373
=3.1 million
Therefor , the company's profit in the year 2003 is $3.1 million

Three dressers are placed side by side one dresser is 2 feet 9 inches wide , another is 2 feet 7 inches wide , and the third 3 feet 11 inches wide . How wide are they combined
Answer:
18 feet 3 inches
Step-by-step explanation:
4 feet 7 inches + 6 feet 11 inches + 6 feet 9 inches =
10 feet 18 inches + 6 feet 9 inches =
16 feet 27 inches =18 feet 3 inches
Answer: 9.25 Feet
Step-by-step explanation:
Step 1: Take all the feet add them together = 7Ft or 84 inches
Step 2: Now add all the inches together to = 27 inches
Step 3: Add 27 + 84 = 111
Step 4: Divide that by 12 cause 1 foot = 12 inches
Step 5: should equal 9.25 :)

Help geometry what I m jlf
Picture provided
Answer:
[tex]\angle\,JLF = 114^o[/tex] which agrees with option"B" of the possible answers listed
Step-by-step explanation:
Notice that in order to solve this problem (find angle JLF) , we need to find the value of the angle defined by JLG and subtract it from [tex]180^o[/tex], since they are supplementary angles. So we focus on such, and start by drawing the radii that connects the center of the circle (point "O") to points G and H, in order to observe the central angles that are given to us as [tex]90^o[/tex] and [tex]138^o[/tex]. (see attached image)
We put our efforts into solving the right angle triangle denoted with green borders.
Notice as well, that the triangle JOH that is formed with the two radii and the segment that joins point J to point G, is an isosceles triangle, and therefore the two angles opposite to these equal radius sides, must be equal. We see that angle JOH can be calculated by : [tex]360^o-90^o-138^o=132^o[/tex]
Therefore, the two equal acute angles in the triangle JOH should add to:
[tex]180^o-132^o=48^o[/tex] resulting then in each small acute angle of measure [tex]24^o[/tex].
Now referring to the green sided right angle triangle we can find find angle JLG, using: [tex]180^o-24^o-90^o=66^o[/tex]
Finally, the requested measure of angle JLF is obtained via: [tex]180^o-66^o=114^o[/tex]
Not so bad after an F- I guess.

What is the value of n?
Answer:
85°
To get this,know that the total angle of triangle is 180°[(n-2)180] n=number of sides.Total angle on a straight line is 180°.
There are 3 angle you need to calculate.
Upper angle:180-133=47°
Right angle:180-142=38°
Left angle:180°-47°-38°=95°
n+95°=180°
n=180°-95°=85°

Cindy dissolves 19 1 /4 grams of drink mix in 1 3 /4 ounces of water. What is the unit rate in grams of drink mix per ounce of water?
Answer:
11 grams of drink mix per ounce of water
Step-by-step explanation:
I converted both numbers to decimals to get 19.25 and 1.75, then divided the amount of drink mix by the amount of water.
Answer:
11 gm mix : 1 ounce water
Step-by-step explanation:
We find 1/7 of 19.75gm = 2.75
Then we multiply by 4 = 11
We have found our ounce rate to be 11 gm : 1 ounce water
The graph of a proportional relationship passes through (9, 18) and (1, y). Find y.
Answer:
2

Answer:
[tex]3\dfrac{5}{8}[/tex] pizzas.
Step-by-step explanation:
It is given that Aisha and her friends ate [tex]2\dfrac{1}{2}[/tex] pizzas.
After the party, the remaining pizza is [tex]1\dfrac{1}{8}[/tex] pizzas.
Now,
[tex]2\dfrac{1}{2}=\dfrac{4+1}{2}=\dfrac{5}{2}[/tex]
[tex]1\dfrac{1}{8}=\dfrac{8+1}{8}=\dfrac{9}{8}[/tex]
Pizzas at the starting = Pizza eaten by Aisha and her friends + Remaining pizza
[tex]=\dfrac{5}{2}+\dfrac{9}{8}[/tex]
[tex]=\dfrac{20+9}{8}[/tex]
[tex]=\dfrac{29}{8}[/tex]
[tex]=3\dfrac{5}{8}[/tex]
Therefore, [tex]3\dfrac{5}{8}[/tex] pizzas were there at the start of the party.

How to check that a trinomial is a perfect square ?
Answer:
Step-by-step explanation:
multiply the two square roots together and then by two. You should get the positive or negative version of the other term. Once again, if this is not the case, you do not have a perfect square trinomial. For example, in the trinomial x2 - 12x + 36, both x2 and 36 are perfect squares.

What additional information is needed to determine that ΔABC ≅ ΔEDC using the HL method of congruence? answers: A) ≅ B) No additional information is needed. C) ≅ D) ∠ACB ≅ ∠ECD
Answer:
AC congruent to EC
Step-by-step explanation:
This problem is asking specifically to prove triangles congruent using HL.
HL is a method of proving triangles congruent. HL stands for Hypotenuse-Leg. If you can show that the hypotenuse and leg of one right triangle are congruent to the hypotenuse and leg, respectively, of another triangle, then the triangles are congruent.
Looking at triangle ABC and EDC, we see that the legs AB and ED are congruent. We already have a pair of corresponding congruent legs. Now we need a pair of hypotenuses.
You need AC congruent to EC.
Answer:
AC congruent to EC
