) Dan bought 5 new baseball trading cards to add to his collection. The next
day his dog ate half of his collection. There are now only 32 cards left.
How many cards did Dan start with ?
Answers
Answer:
Start by writing an equation with a a variable (call it X) to represent the number Dan started with.
He started with X, added 5 more, then his dog took half or divide by 2. He then ended up with 32. Solve:
(X +5)/2 = 32 Multiply each side by 2
X+5 = 64 Subtract 5 from both sides
X = 59
Answer:
59
Step-by-step explanation:
Let the Dan's baseball be x
When 5 added
(x + 5)
Dog ate half
(x + 5)/2
(x + 5)/2 = 32
(x + 5) = 32(2)
x + 5 = 64
x = 64 - 5
x = 59

The range of the plotted function is the set of y values that it takes on. The curve is continuous and ranges from y = -2 (at the leftmost point (-11, -2)) up to y = 10 (at the rightmost point (11, 10)).
However, the unfilled circle at the left endpoint means that y = -2 is not actually included in the range.
So the range in this case is -2 < y ≤ 10. (note the strict inequality on the left)

Using the quadratic formula:
x = [-b +- sqr root (b^2 - 4ac)] / 2a
x = [-0 +- sqr root (0^2 - 4*3 *-1] / -2 * 3
x = +- sqr root (12) / -6
x = +2 * sqr root (3) /-6
x1 = + sqr root (3) / -3
x2 = -sqr root (3) / -3

A circle has a circumference of 18cm. What is the diameter of the circle?
Answers
Answer:
Around 5.73. The exact answer is 18/pi. Why? The diameter is twice the radius (2r) The formula of the circumference if 2 pi R
if we divide 18, the circumference by pi, we get the diameter.
Step-by-step explanation:
Answer:
18/π
Step-by-step explanation:
Since 2 × π × r is the circumference of the circle,
2πr = 18
πr = 9
r = 9/π
Since the diameter is 2x the radius,
2r = d
2 × 9/π = d
18/π = d

Answers
Answer: x = 115/2 and 119/6
You can simplify the answer.
Step-by-step explanation:
(2x + 5)(6x -1)= 120
120 = (2x +5) and (6x -1) = 120
120 - 5 = 2x and 6x = 120 - 1
115 = 2x and 6x = 119
115/2 = x and x = 119/6
Answer:
=>(2x+5)(6x-1)=120
=>2x(6x-1)+5(6x-1)
=>12x>2-2x+30x-5=120
=>12x>2+28x-5-120=0
=>12x>2+28x-125=0

Jay went to am amusement park. The park charges an entrance fee of $10.50 and $4.50 for every ride. Jay spent 46.50 on entrance fees and rides. Which function can be used to find the number of rides he went on?
Answers
And total amount spent on the ride and entry fees be y
Entry fees of the park = $10.50
Also, Charge for each ride is given to be $4.50
So, The linear function which describes the situation :
y = 10.50 + 4.50x
Now, Its given that Jay spent a total of $46.50 in the park
So, to find total number of rides taken substitute y = 46.50 in the above linear equation.
⇒ 46.50 = 10.50 + 4.50x
⇒ 4.50x = 36
⇒ x ≈ 8
Thus, Number of rides taken = 8

The expression two pi parentheses RH plus R to the power of two parentheses represents the total surface area of a cylinder with height H in radius R what is the surface area of the cylinder with a height of 6 cm and a radius 2 cm
Answers
Answer:
100.6cm2
Step-by-step explanation:
The mathematical expression wil become
[tex]2\pi(rh + {r}^{2} )[/tex]
The TSA of a cylinder is
[tex]2\pi \: rh + \pi {r}^{2} + \pi {r}^{2} [/tex]
When simplified, we have
[tex]2\pi \: rh + 2\pi {r}^{2} = 2\pi(rh + {r}^{2} )[/tex]
So indirectly, the expression is the same as total surface area of a cylinder.
So all you have to do is substitute the height and radius into any of the formulas .
[tex]2 \times \frac{22}{7} ( (2 \times 6) + {2}^{2} )[/tex]
[tex]2 \times \frac{22}{7} (12 + 4) \\ 2 \times \frac{22}{7} \times 16 \\ \frac{22 \times 2 \times 16}{7} \\ \frac{22 \times 32}{7} \\ \frac{704}{7} = 100.57 {cm}^{2} \\ = 100.6 {cm}^{2} [/tex]

Answer:
The second and third boxes. m=-10/4 & -5/2 & the last one
Step-by-step explanation:
We know the answer is negative so we need to add a larger number to get the 3/4 to the negatives. 3-10= -7, so -10/4 and -5/2 is equal to -10/4
Answer:
The second one m= -10/4, the third one m= -5/2, and the last one -5/4+m= -15/4
Step-by-step explanation:
You find m by solving -7/4 - 3/4 = m. Thats the second option -10/4.
When you simplify, you get -5/2, the third option.
Finally, -5/4+m= -15/4 is equal to -15/4 -(-5/4)=m. Subract and you get -10/4. That makes the original equation equal to the last option.
