Answer:
Mrs. Delgado purchased 6 notebooks and 2 packages of pens.
Step-by-step explanation:
Given that Mrs. Delgado purchased notebooks at 2 for $ 5 and pens at $ 2 per package, and she spent $ 19 for a total of 8 items, to determine how many notebooks and pens did she buy the following calculation must be performed:
5/2 = 2.5
8 x 2.5 + 0 x 2 = 20
6 x 2.5 + 2 x 2 = 19
Therefore, Mrs. Delgado purchased 6 notebooks and 2 packages of pens.

Which combined function gives the total surface area of the two bases of the cylinder? A. f + g B. f – g C. g – f D. f · g
Answer:
C. g - fStep-by-step explanation:
Total surface area of a cylinder with height 5 is:
A = 2πrh + 2πr² = 10πr + 2πr²If we substitute r with x, we get:
g(x) - full surface areaf(x) - surface areaTotal surface area of two bases:

Answer: 16.5
formula:
c^2 = a^2 + b^2
(a and b are the lines that form a right angle and c is the line that doesn’t)
a = 16
c = 23
Answer:
16.5
Step-by-step explanation:
a² + b² = c²
x² + 16² = 23²
x² + 256 = 529
x² = 273
x = √(273)

hi whats th median price of the items for 9.00 8.00 8.00 7.00 6.00
Answer:
8.00
Step-by-step explanation:
to find the median, you have to order all your numbers from least to greatest (6.00, 7.00, 8.00, 8.00, 9.00) then find the number in the MIDDLE. that number would be 8.00 so therefore the median is 8.00.

If steak costs $12.55 per pound, what will be the total cost of 0.6 pounds of steak?\
Answer:
Solve for X; whereas lb=pound, $=cost
1lb = $12.55
0.6lb = $X; therefore 6/10 lb = $X
Rewrite:
$12.55/1 lb = $X/6/10 lb; therefore $12.55/1 lb = 10/6(X); 10X=$12.55(6); 10X=$75.30; X=$75.30/10
X=$7.53 for .6 lbs.

Part b: Find the length of the sidewalk. The walk is the hypotenuse of a right 30-60-90 triangle with horizontal side 2√3. Using the 30° angle as the reference angle, we get the following from the definition of the cosine function:
cos 30° = adj / hyp, or:
√3 2√3
------- = --------
2 hyp
This simplifies to
1 2
-------- = -------
2 hyp
Cross multiplying results in: hyp = 4. The sidewalk length is 4 miles.
a. The width of the park can be found using the sine function, the now-known hypotenuse and the 30° angle:
1 opposite side
sin 30 degrees = ----- = ------------------------- or 2(opp side) = 4.
2 4
Then the opp side, which is the width of the park, is 2.

Candice has 40 bowls
She shared the bows between her 2 friends
Cindy has 3/8 of the bow
40×3/8
= 15
Elsa has 2/5 of the bow
40×2/5
= 16
Therefore elsa received more bows, she received 1 bow greater than Cindy

A stepladder has an angle of elevation of 60° with the front of the house. The length of the stepladder is 24 feet. At what height does the stepladder meet the house?
Answer:
20.78 feets
Step-by-step explanation:
Based on the solution diagram attached below :
The height at which the step ladder meets the house can be obtained thus :
Using trigonometry :
Sin θ = opposite / hypotenus
Sin θ = h / 24
Sin 60 = h / 24
0.8660254 = h/24
Height, h = 0.8660254 * 24
Height, h = 20.78 feets
The path of a projectile launched from a 26-ft-tall tower is modeled by the equation y = −16t2 + 64t + 26. What is the maximum height, in feet, reached by the projectile?
Answer:
The maximum height of the projectile is 90 ft
Step-by-step explanation:
Here, we want to get the maximum height reached by the projectile
The answer here will be the y-coordinate value of the vertex form of the given equation
so firstly, we have to write the equation in the vertex form
We have this as;
y = -16t^2 + 64t + 26
That will be;
y = a(x-h)^2 + k
y = -16(x-2)^2 + 90
where the vertex of the equation is;
(-h,k)
K
in this case is 90 and thus, that is the maximum height of the projectile
