Answer:
Lesley purchased 1 oval bead and 4 round beands.
Step-by-step explanation:
Given that Lesley purchased 5 beads at a total cost of 80 cents, and the round beads cost 15 cents each, and the oval beads cost 20 each, to determine what are the numbers of round and oval beads Kelsey purchased, the following calculation must be performed :
5 x 0.20 + 0 x 0.15 = 1
4 x 0.20 + 1 x 0.15 = 0.95
2 x 0.20 + 3 x 0.15 = 0.85
1 x 0.20 + 4 x 0.15 = 0.80
Therefore, Lesley purchased 1 oval bead and 4 round beands.
5 + {[2 X (14 - 9)] - 1}
Answer:
14
Step-by-step explanation:
[tex] 5 + (2 \times (14 - 9) - 1) \\ = 5 + (2 \times 5) - 1 \\ = 5 + (10 - 1) \\ = 5 + 9 \\ = 14[/tex]
A max subscription for Twitch, a streaming service, costs a flat fee of $25. You can then also buy small subscriptions for others for $5 per subscription. Johnny is trying to budget the amount of money he wants to spend.
Let y represent the total amount of money spent, and x represent the number of small subscriptions he purchases.
Answer:
y = 25 + 5x
Step-by-step explanation:
Since the cost of Twitch is $25 no matter what, that will be our y-intercept (essentially when no other subscriptions are bought). Since with every purchase x we make, we spend an additional $5, the slope of the line (x coefficient) will be 5.

Find the measure of the missing angle.
Answer:
68 degrees
Step-by-step explanation:
That angle counts as 90 degrees, so all you need to do is subtract 90 from 22 because 90 degrees is the full angle.
90-22=68
Find the surface area of the regular pyramids. Round your answer to the nearest tenth.
Answer:
S.A = 147.35 cm²
Step-by-step explanation:
Surface area of the triangular pyramid = base area + ½(perimeter of base*slant height)
Base area = ½*bh
b = 7 cm
h = 6.1 cm
Base area = ½*7*6.1 = 21.35 cm²
Perimeter of triangular base = 7 + 7 + 7 = 21 cm
slant height = 12 cm
Plug in the values into the equation
S.A = 21.35 + ½(21*12)
S.A = 21.35 + 126
S.A = 147.35 cm²

The product of two numbers is 41. One of the numbers
is the complex number 5+4i. What is the other
number?
A. 5-4i
B. 5+4i
C. -5-4i
D. -5+4i
E. 41/5-4i
===================================================
Work Shown:
x = the other number
(5+4i)*x = 41
x = 41/(5+4i)
x = 41*(5-4i)/( (5+4i)*(5-4i) ) ..... see note below
x = 41*(5-4i)/( 41 )
x = (41/41)*(5-4i)
x = 5 - 4i
As a way to check, (5+4i)*(5-4i) = 5^2+4^2 = 25+16 = 41
The rule used is (a-bi)(a+bi) = a^2 + b^2
-----------
Note: I multiplied top and bottom by (5-4i) to get rid of the imaginary term in the denominator.

Help please! Much appreciated
Answer:
a. Sin B = 15/17
b. Cos B = 8/17
c. Tan B = 15/8
Step-by-step explanation:
Recall: SOHCAHTOA
Reference angle = B
Opp = 15
Adjacent = 8
Hypotenuse = 17
a. Sin B = Opp/Hyp (applying SOH)
Substitute
Sin B = 15/17
b. Cos B = Adj/Hyp
Substitute
Cos B = 8/17
c. Tan B = Opp/Adj
Substitute
Tan B = 15/8

Answer:
37.9 degrees
Step-by-step explanation:
Using the law of sines, [tex]\frac{\sin(m\angle C)}{21}=\frac{\sin(47^\text{o})}{25}[/tex]. It follows that [tex]\sin (m\angle C) = \frac{21\sin(47^\text{o})}{25} \approx 0.6143371[/tex]. Therefore, [tex]m\angle C = \sin^{-1}(0.6143371)=37.9^\text{o}[/tex].
