Which value of x makes the equation 2 + 8 = 15
true?
Answer:
5
Step-by-step explanation:
Answer:
x = 3 [tex]\frac{1}{2}[/tex]
Step-by-step explanation:
there's no x in the equation you wrote.
Did you mean?
2x + 8 = 15
Subtract 8 from both sides
2x = 7
Divide both sides by 2
x = 7/2
x = 3 [tex]\frac{1}{2}[/tex]

Answer:
A and B are functions
Step-by-step explanation:
for A, none of the x's repeat which makes it a FUNCTION
for B, when it starts with x^2, it will always be a FUNCTION (its a quadratic)
for C, 10 repeats for the x so it is NOT A FUNCTION

total surface area of cylinder=?
we have
total surface area of cylinder=2πr²+2πrh
2πr(r+h)2π*2(2+8)40π or 125.66cm²total surface area of cylinder40π or 125.66cm².
Find the surface area of the cylinder.
___________________Solution :-Given Information :-Radius of the Cylinder ➢ 2 cmHeight of the Cylinder ➢ 8 cm Value of π (pi) (not given) ➢ 3.14To Find :-Surface Area of the CylinderFormula Used :-Area of cylinder = 2πr( r + h ) Calculation :-Substituting the values given in the formula, We get,
⇒ Area of Cylinder = 2 × 3.14 × 2 ( 2 + 8 )
⇒ Area of cylinder = 2 × 3.14 × 2 ( 10 )
⇒ Area of cylinder = 2 × 3.14 × 20
Calculating further, We get,
⇒ Area of cylinder = 125.66 cm²
___________________Final Answer :- Area of cylinder = 125.66 cm²____________________Name the conic section formed when a plane cuts a right circular cone parallel to its base.
1) circle
2)parabola
3)ellipse
4) hyperbola
Will mark it the brainliest plsss fast!
Answer:
option 1.
circle
Step-by-step explanation:
A section is formed when a solid shape is sliced into two. A conic section is therefore formed when a cone, is sliced into two.
What determines the shape of the section now, is the angle at which the cone was sliced.
Normally, the base of a cone is a circle. If we slice a cone using a straight line, which runs parallel to its base, we will still get another perfect cone, but with a smaller height.
If we look at the flat portion of the cone after it has been sliced, we will see that the cross-section is a circle.

QUESTION:
What is mBDG?
Answer:
242
Step-by-step explanation:
Circles have a total of 360°
mDBG does not include mBA or mGA
This means that mDBG = 360 - ( mBA + mGA )
mBA = 28° ( this is given )
mGA = 90° ( this is also given; it's indicated by the right angle )
Thus, mDBG = 360 - ( 28 + 90 )
28 + 90 = 118
mDBG = 360 - 118
360 - 118 = 242
Hence, mDBG = 242

Mary received an $80 gift card for a coffee store. She used it in buying some coffee that cost $8.21 per pound. After buying the coffee she had $30.74 left on her card. How many pounds of coffee did she buy?
Answer:
Mary bought 6 pounds of coffee
Step-by-step explanation:
80 - 30.74 = 49.26
49.26 divided by 8.21 =6
A dirt bike has been marked down 12% and now costs $4286.70. What was the original cost?
Answer:
$4871.25
Step-by-step explanation:
You know that the dirt bike has been "marked down," so to find the percentage of the original cost, subtract 0.12 from 1 to get 0.88. Then, define x as the original cost, and set up an equation:
0.88x = 4286.70
You know that 4286.70 is 88% of the original cost, so 0.88 times the original cost will equal the marked down cost. Now, divide both sides by 0.88 to get the answer:
x = 4871.25

2/3 as long = multiply by 2 1/2 of the time.
2.5 x 2/3 = 1.66666667
Simplify:
1.66666667 = 1 2/3
Answer:
Corine= 2 1/2 hours
Levon= 1 2/3 hours

please answer correctly !!!!! Will mark Brianliest !!!!!!!!!!!!!!
Answer:
44.1
Step-by-step explanation:
Cosine = Adjacent over Hypotenuse
Adjacent of ∠T = 28 and hypotenuse = 39
Which means that [tex]cos(x)=\frac{28}{39}[/tex]
Now we solve for x
To get rid of the "cos" we take the inverse of cos ( which is [tex]cos^-^1[/tex] ) and apply it to each side
[tex]cos^-^1((cos)x) = x\\cos^-^1(\frac{28}{39} )=44.11461855[/tex]
We're left with x = 44.11461855
Our last step is to round to the nearest tenth and we get that the answer is 44.1
3) Determine the numbers of solutions for 4x + 8 = 12x.
Answer:
x = 1
Step-by-step explanation:
4x + 8 = 12x
4 (1) + 8 = 12 (1)
4 + 8 = 12
12 = 12
your answer is x = 1
Answer:
4x+8=12x
8=8x subtract 4 on both sides
1=x divide by 8 on both sides

His average speed was 57 miles per hour
On a ship the ratio of crew members to passengers is 1:15. There are 540 passengers. How many crew members are there?
Answer: 36
Step-by-step explanation: Keep multiplying 15 until you get 540. 36 * 15 is 540
Answer:
36 Crew members
Step-by-step explanation:
Divide 540 by 15, to find how much the new amount of passengers had increased. It should be 36.
Now to keep the ration even, you need to multiply the amount of Crew members by 36 too.
Double checking your answer:1/15=0.06666666667...
36/540=0.06666666667...
There's probably other ways to solve this, this is just how I did it.
