Answer:
24
Step-by-step explanation:
First, start off by subtracting the cost of the coffee ($5.96) from the total cost of $32.12. This would give you $26.16. From here, if you multiply 24 by the cost of each doughnut ($1.09) you would get $26.16 which is the total amount of money that was spent on doughnuts. Miss Solan bought 24 doughnuts.

Multiply 6/5 by the reciprocal of (-3/8)
Answer:
-48/15, simplified to -16/5
Step-by-step explanation:
The reciprocal of -3/8 is -8/3. So the equation will be 6/5 x -8/3. Multiply numerators then multiply denominators to get -48/15. This can simplify to -16/5 by dividing both by 3.
Answer:
Step-by-step explanation:
hello :
6/5 by the reciprocal of (-3/8) means : ( 6/5 )(-8/3) = - 48/15 = -16/5

Answer:
11.1 feet
Step-by-step explanation:
When you are given a right triangle with a given angle and side, you can use
trigonometric functions to calculate missing side lengths or inverse functions for angles based on this information.
These ratios can be remembered by the mnemonic:
SOH CAH TOA.
S O H → Sin (Sine) = Opposite / Hypotenuse
C A H → Cos (Cosine) = Adjacent / Hypotenuse
T O A → Tan (Tangent) = Opposite / Adjacent
______________________________________
The Opposite side is the side directly across from the angle, The adjacent (next to) side is the side other than the hypotenuse or opposite side, and the hypotenuse is the longest side.
Given that we are trying to find the adjacent side, we must use the cos (cosine) function because that can be multiplied by the hypotenuse to give us the adjacent side we are looking for.
Therefore, 36 [Hypotenuse Side] × cos(72°) = Adjacent Side.
Because: 36 = Hypotenuse Side.
cos(72)° = Adjacent Side / Hypotenuse Side.
36 × cos(72°) =
36 × 0.309016994374... = 11.12461179749... ≈ 11.1

Answer:
area = 73.37 cm²
Step-by-step explanation:
area of circle:
A = π5² = 78.5 cm²
area of 80° segment:
(80/360)(78.5) = 17.44 cm²
area of isosceles triangle w/ 5 cm legs and 80° angle:
sin 40° = b/5
0.6428 = b/5
b = 3.214
base = 2(3.21) = 6.43 (we only figured for one-half of the base)
cos 40° = h/5
0.7660 = h/5
height = 3.83
A = 1/2(6.43)(3.83) = 12.31 cm²
area of unshaded part:
17.44 - 12.31 = 5.13 cm²
area of total shaded part:
78.5 - 5.13 = 73.37 cm²

Answer:
y ≤ 66.28 -> -∞
Step-by-step explanation:
y = a (x-h)² + k ... (h,k): vertex
y = - 32x² + 90x + 3
= -32 (x² - (90/32)x + (90/64)²) + (3 + (32)*(90/64)²)
= -32 (x² - 2*(90/64)x + (90/64)²) + (3+63.28) ... 90/64=1.41
= -32 (x - 1.41)² + 66.28
h = 1.41
k = 66.28 .... extremum of y value
y ≤ 66.28 (y is real number)
A square pyramid has a volume of 297 cubed feet. The width and length of the pyramid are
both 9. feet. Find the height of the pyramid.
Answer:
11
Step-by-step explanation:
H =V/(LxW)/3
H = 297/(9x9)/3
H = 297/(81)/3
H = 297/27
H = 11
Therefore, the height of the pyramid is 11ft square

Harold has a round trampoline with a radius of 1 yard. What is the trampoline's diameter?
Answer:
2 yards
Step-by-step explanation:
As per its definition, the diameter is the largest line that can be drawn from end to end of a circle, the diameter will always pass through the center of a cricle. The radius of a circle is a line drawn from the center of a circle to one of its sides. The diameter is always twice the measure of the raidus.
Applying this knowledge here, when given a radius of (1) yard, the diameter will be twice the length, and thus it will be (2) yards.
Can someone help me and solve for x
Answer:
x ≈ 14.6
Step-by-step explanation:
Assuming the triangle is right.
Using the sine ratio
sin55° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{12}{x}[/tex] ( multiply both sides by x )
x × sin55° = 12 ( divide both sides by sin55°
x = [tex]\frac{12}{sin55}[/tex] ≈ 14.6 ( to 1 dec. place )
Answer:
24? because the measure of 12 is half the size of x then the other half should be 12 too so i think 24. I AM VERY SORRY IF ITS WRONG!!!!!!!
What is the equation of the line that passes through the point (-2, 0) and has a slope of -2?
Answer:
y=-2(x+2)
Step-by-step explanation:
plug in(-2,0) into y-y1=m(x-x1)
y=m(x+2)
slope =m=-2
y=-2(x+2)
how do you solve 2x+4y=7 and -2x +3y=14
Answer:
y=3 x= -5/2
Step-by-step explanation:
simultaneous equations
2x + 4y = 7 ------ eq 1
-2x + 3y = 14 --------eq2
(different signs add)
(eq 2 + eq 1)
-2x +(-2x) = 0
4y+3y = 7y
7+14 = 21
7y= 21
(divide both sides by 7)
y= 21/7= 3
2x + 4(3) = 7
2x+ 12=7
2x = 7-12
2x = -5
x= -5/2

Which of these is NOT an example of lateral surface area? A. The label of a soup can. B. Painting the walls of your bedroom. C. The paper wrapper of an ice cream cone. D. The air in a basketball.
Answer:
D
Step-by-step explanation:
The lateral surface area is the area of all the sides of a 3-dimensional object excluding its base and top.
The total surface area of a room would be the walls of the room. this is because the roof and the floor would be excluded
The wrapper of an ice-cream cone excludes the base and the top. Thus it is an example of the lateral surface area

The equation of a circle centered at the orgin is x^2 + y^2 = 16. What is the radius of the circle
Given:
The equation of the circle is:
[tex]x^2+y^2=16[/tex]
To find:
The radius of the circle.
Solution:
The standard form of a circle is:
[tex](x-h)^2+(y-k)^2=r^2[/tex] ...(i)
Where, (h,k) is the center and r is the radius.
We have,
[tex]x^2+y^2=16[/tex]
In can be written as:
[tex]x^2+y^2=4^2[/tex] ...(ii)
On comparing (i) and (ii), we get
[tex]h=0[/tex]
[tex]k=0[/tex]
[tex]r=4[/tex]
Here, the center of the circle is the origin and the radius is equal to 4 units.
Therefore, the radius of the given circle is 4 units.
