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°

What is the area of circle circumscribing a triangle?
An imaginary tangent line stretching from the triangle's two sides plus a section of the curve that is tangent to one side create this combination. The formula for the radius of a circle enclosing a triangle is
r = ABC / 4A.
Solution:
area of sector ABC = 85/360 × π × (7.3)² cm²
= 39.53 cm²
area of triangle ABC = 1/2 × 9 × 5.7 cm²
= 25.65 cm²
area of shaded region = area of sectot ABC ₋ area of triangle ABC
= 39.53 ₋ 25.65
= 13.88 cm²
Hence the area of shaded region is 13.88 cm²

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
which expression can he used to find the surface area of the following sqare pyramid
Answer:
answer: A
Because when doing area for triangles its
base × height ÷ 2 so for 1 triangle it would be 5 × 4 = 20 then ÷ by 2 so 20 ÷ 2 = 10 Since there are 4 triangles we will have to add 10 4 times and then for the square it's easily just 4 × 4 = 16
so it would come out to 16 + 10 + 10 + 10 + 10 =
A cylinder has a volume of 200in^3. Determine the volume of a cone whose radius and height are equal to that of the cylinder
Answer:
66.67 in^3
Step-by-step explanation:
volume of a cylinder = nr^2h
Volume of a cone = 1/3(nr^2h)
n = 22/7
r = radius
the volume of a cone is 1/3 that of a cylinder
volume of the cone = 1/3 x (200) = 66.67 in^3

Answer: B. Yes, Because 3^2 + 4^2 = 5^2
Step-by-step explanation:
ONLY FOR RIGHT TRIANGLES
the biggest side is square root of the sum of the smaller sides squared(a^2 + b^2 = c^2)
So:
3^2 + 4^2 = 5^2
9 + 16 = 25
25 = 25

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

The world's largest pizza is 131 feet in diameter. What is the
area of this gigantic ple?
Answer:
1,665
Step-by-step explanation:
First find the area of the whole pizza. The diameter is given as 131 feet, so r would be 131/2 = 65.5 feet. I will use 3.14 for PI since the problem doesn't say what value to use. Each slice has an area of about 269.43 square feet and a crust length of 8.23 feet.

Answer:
$65
Step-by-step explanation:
x is the number of items sold, and y is the profit, so we need to calculate
y = 35x - 250
where x=9
y = 35*9 - 250 = 315 - 250 = 65
So the total profit is 65 dollars

The percentage of people wearing basket ball shoe is,
= 32%
What is Percentage?A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
here, we have,
To Calculate the percent of a number , divide the number by whole number and multiply by 100.
In a shoe store survey there are 200 customers.
Given in the table is that, people using basketball shoes, not using basket shoes and then there is also classification of people using running or non running shoes.
We have been asked what percentage of people have basketball shoes.
People having basket ball shoes = 0.18 × 200 + 0.28 ×200
= 64
Thus, The percentage of people wearing basket ball shoe is,
= 64/200 x 100
= 32 %
Hence, The percentage of people wearing basket ball shoe is,
= 32%

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

Malik got a 200 cafe gift on January 1. He always orders decaf mochas which cost 5 each. At the end of January, maliks gift card has 125 left. Write an equation with x as your variable.
Answer:
200 - 5x = 125
Step-by-step explanation:
Let the number of orders made by Malik in the month of January = x
Each order costs = $5
Total cost of decaf mochas in one order = $5x
Malik had cake gift on 1st of January = $200
Amount of money left with Malik at the end of January = $125
Therefore, equation representing this situation will be,
200 - 5x = 125

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
152° is an exterior angle of the triangle , then
x + x = 152
2x = 152 ( divide both sides by 2 )
x = 76
Answer:
x+x=152° (sum of two opposite interior angles is equal to exterior angle)
2x=152°
x=76 °
