If you know that cosine of the obtuse supplementary angle -0.3456 what can you determine about the acute angle
Answer:
69.8°
Step-by-step explanation:
Since cosФ = -0.3456
Ф = cos⁻¹(-0.3456)
Ф = 110.2°
Since the angles are supplementary, let the acute angle be x
So, x + 110.2° = 180°
x = 180° - 110.2°
x = 69.8°

John has coins in a jar. Five of the coins are pennies, 8 are dimes, and 3 are
quarters. John randomly selects a coin from the jar and without replacing it
randomly selects another coin. What is the probability that he selects a dime and
then a quarter?
The probability that he selects a dime and then a quarter without replacement is 1/10
What is probability?Probability is a measure of the likelihood of an event occurring. The probability formula is defined as the possibility of an event happening is equal to the ratio of the number of favorable outcomes and the total number of outcomes. Probability of event to happen P(E) = Number of favorable outcomes/Total Number of outcomes.
Given here: John has 8 dimes 5 pennies and 3 quarters.
Total number of coins that John has is =8+5+3
=16
Thus the probability of picking a dime is P(dime)= 8/16
=1/2
Therefore the conditional probability that John picks a dime and then a quarter is given by
P(dime/quarter)=1/2×3/15 ( As the dime picked is not replaced)
=1/10
Hence, the probability that he selects a dime and then a quarter without replacement is 1/10

x = ___ units
Answer:
x = 16 units
Step-by-step explanation:
∆ABC is a 45-45-90 triangle, and ∆BCD is a 30-60-90 triangle.
If side opposite of 90° [∆] = x, side opposite of 45° [∆] = x / √2 = x √ 2 / 2.
Given side AC is opposite of 90° [∆ABC] = 32 √ 2, side opposite of 45° [∆ABC] = 32 √ 2 / √ 2 = 32 which is AB or BC.
Since side BC is part of BCD.
Side opposite of 90° [∆BCD] = BC = 32.
Since x is opposite of 30° [∆BCD].
x = Side opposite of 90° [∆BCD] / 2 = 32 / 2 = 16.

The drawing shows a stack of alternating cups. The cups are 9.2 cm high. How many cups will fit in a door that is 211.77 cm high?
Answer:
The total number of whole cups that we can fit in the dispenser is 25
Step-by-step explanation:
It is given that the height of each cup is 20 cm.
But when we stack them one on top of the other, they only add a height of 0.8 to the stack.
The stack of cups has to be put in a dispenser of height 30 cm.
So we need o find out how many cups can fit in the dispenser.
Since the first cup is 20 cm high, the height cannot be reduced. So the space to fit in the remaining cups in the stack is only 30-20 cm as that’s the remaining space in the dispenser
So,
30 - 20 = 10 cm
To stack the other cups we have 10 cm of height remaining
As we know that addition of each adds 0.8 cm to the stack, the total number of cups that can be fit in the dispenser can be calculated by the following equation. Let the number of cups other than the first cup be denoted by ‘x’.
10 + 0.8x = 30
0.8x = 20
x = 25
The total number of cups that we can fit in dispenser is 25

Find the area of triangleABC to the nearest tenth.
Answer:
62.3 units²
Step-by-step explanation:
We would apply the formula for area of a triangle given an included angle, which is A = ½*ab*sin C
Where,
a = 11
b = 14
C = 54°
Substitute
Area = ½*11*14*sin 54
Area = 62.2943085 ≈ 62.3 units² (nearest tenth)
A wrestling coach is entering his team in a tournament. There is a $75 fee for each team entered, plus a $5 fee for each wrestler entered.
The total cost to enter a team in a wrestling tournament can be represented by the equation f = 5w + 75, where f is the total fee and w is the
number of wrestlers entered.
if the total fee is $135, how many wrestlers does the coach enter in the tournament?
O A 12
OB. 15
OC 27
OD. 42
O E 60
Answer:
12 wrestlers
Step-by-step explanation:
First you do 135-75=60 to find the cost he payed for just the wrestlers
then each wrestlers cost 5 dollar so you do 60/5 to get a total of 12 wrestlers

Amal designed a silver necklace pendant in the shape of a cone. The slant height of the cone is 5 millimeters, and the radius of the cone is 3 millimeters.
What is the volume of the silver pendant, rounded to the nearest tenth?
Use 3.14 for π.
Answer:
37.7 mm³
Step-by-step explanation:
Step 1
We find the height of the cone
we are given slant height = 5mm and radius = 3mm
Height = √l² - r²
Where l = Slant height
Hence
h = √5² - 3²
h = √25 - 9
h = √16
h = 4
Hence, the height of the cone = 4mm
Step 2
We can proceed to calculate the volume of the cone
Volume = 1/3 πr²h
π = 3.14
Hence,
Volume = 1/3 × 3.14 × 3² × 4
= 37.68 mm³
Approximately, Volume of the cone to the nearest tenth = 37.7 mm³
Answer:37.7
mm3

Mrs. Roberts sewed m shirts using 2 yards of cloth for each shirt. She also sewed (m+2) dresses, using 5 yards of cloth for each dress. A) How much cloth did she use altogether? Give your answer in terms of m. B) If m= 7, find how much more cloth she used to sew the dresses than the shirts.
Answer:
7m + 10
31 yards
Step-by-step explanation:
Shirts :
Number of shirts sewed = m
Yards of cloth used per shirt = 2 yards
Number of dresses sewed = m + 2
Yards of cloth used per dress = 5 yards
Cloth used altogether :
Cloths used for shirt = 2 * m = 2m
Cloth used for dress = 5 * (m+2) = 5m + 10
2m + (5m + 10) = 7m + 10
If m = 7
Cloth used for dress - Cloth used for shirt
(5(7) + 10) - (2(7))
(35+10) - 14
45 - 14 = 31 yards
