Margaret is planning a wedding reception. She wants to spend less than her budget of $4,991, and Margaret has already spen
$2,016. The meal price per guest is $25. How many guests, x, can Margaret invite to the reception and stay under budget?
Select the number line that includes the largest number of guests Margaret can invite without exceeding her budget.
Answer:
I'm pretty sure it's C.
Step-by-step explanation:
4,991 - 2,016 is 2975 for the amount of money she has left over after what she spent already. 2975 divided by 25 is 119 for the amount of guests she can serve.

The blimp flying is "237 m" high.
Angle of depressionAccording to the question,
In ΔABC,
∠XCA = ∠CAB = 72°
∠YCB = ∠CBA = 40°
Now,
→ ∠A + ∠B + ∠C = 180°
By putting the values,
72° + 40° + ∠C = 180°
112° + ∠C = 180°
∠C = 180° - 112°
= 68°
By applying Sin Rule,
→ [tex]\frac{AB}{Sin \ 68^{\circ}} = \frac{AC}{Sin \ 40^{\circ}}[/tex]
AC = [tex]\frac{360\times Sin \ 40^{\circ}}{Sin \ 68^{\circ}}[/tex]
We know that,
Area of ΔABC = [tex]\frac{1}{2}[/tex] × AB × AC × Sin 72° ...(Equation 1)
Area of ΔABC = [tex]\frac{1}{2}[/tex] × AB × h ...(Equation 2)
From "Equation 1 and 2",
→ [tex]\frac{1}{2}[/tex] × AB × AC × Sin 72° = [tex]\frac{1}{2}[/tex] × AB × h
h = AC × Sin 72°
By substituting value of "AC",
= [tex]\frac{360\times Sin \ 40^{\circ}}{Sin \ 68^{\circ}}[/tex] × Sin 72°
= 237.36 or, 273 m
Thus the answer above is correct.

Answer:
15,200 ft^2
Step-by-step explanation:
The shape of the playground can be thought of as two rectangles.
The rectangle on the left side measures 2.5 inches by 3 inches.
The rectangle on the right side has a width of 1 inch. The length along the bottom side measures 4.5 inches - 2.5 inches = 2 inches
total area = LW + lw
total area = 3 in. * 2.5 in. + 2 in. * 1 in.
total area = 7.5 in. + 2 in.
total area= 9.5 in.^2
Now we need to convert to the actual area from the scale drawing area.
1 in. = 40 ft
9.5 in.^2 * (40 ft / in.) * (40 ft / in.) = 15,200 ft^2
Answer: 15,200 ft^2

If the length of a side of a square is increased from 4 to 8, which of the following statements is true?
A.) Both area and perimeter are doubled.
B.) Both the area and perimeter are quadrupled.
C.) The perimeter is doubled and the area is quadrupled.
D.) The perimeter is quadrupled and the area is doubled.
Answer:
C.) The perimeter is doubled and the area is quadrupled.
Step-by-step explanation:
Original square: side = 4
Area = side^2 = 4^2 = 16 square units
Perimeter = 4 * side = 4 * 4 = 16 units
Larger square: side = 8
Area = side^2 = 8^2 = 64 square units
Perimeter = 4 * side = 4 * 8 = 32 units
Comparison of areas:
(larger square area)/(original square area) = 64/16 = 4
Comparison of perimeters:
(larger square perimeter)/(original square perimeter) = 32/16 = 2
Answer:
C.) The perimeter is doubled and the area is quadrupled.

B. ( \ sqrt 9.5)
C. ( 3\ sqrt 5)
D. ( 5\ sqrt 3)
Answer: C. [tex]\sqrt[3]{5}[/tex]
Step-by-step explanation: Plato/ Edmentum
The simplified form of square root 45 is 3√5. Therefore, the correct answer is option C.
The given number is √45.
The square root of a number is the inverse operation of squaring a number. The square of a number is the value that is obtained when we multiply the number by itself, while the square root of a number is obtained by finding a number that when squared gives the original number.
Here, factors of 45 = 3×3×5
√45 = √3×3×5
= 3√5
Therefore, the correct answer is option C.

A buoy is floating in the sea and can be seen from the top of a vertical cliff. A boat is travelling from the base
of the cliff directly towards the buoy. The top of the cliff is 142 m above sea level. The angle of depression
from the top of the cliff to the buoy is 40 degrees.
Answer:
169.23m
Step-by-step explanation:.
Let's calculate the base of the cliff. Using SOH CAH TOA identity
Height (opposite) = 142n
Angle of depression = 40°
Required
Base of the cliff
Tan theta = opposite/adjacent
Tan 40 = 142/x
x = 142/tan40
x = 142/0.8391
x = 169.23m
Hence the base of the cliff is 169.23m long

Will all of the words be matched? Yes -
Can we use factorials? Yes -
How many different ways can the answer key be arranged?
P(all correct)

Answer:
Assume that there is a Latin quiz with 10 matching vocabulary questions, and your niece try to match them randomly. Then, the probability that she gets the first item right is

10
since there is only one correct answer for this item out of 10 options. Now, the probability that she gets the second item right is
