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°

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)
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

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
A box has 3 pencils, 5 pens, and 4 markers. What is the probability of randomly pulling out a marker, then after putting it back your friend
grabbing something that is not a pencil?
Answer:
1/4 chance of pulling a pencil then 3/4 for ur frend
Answer:
If I remember correctly, possibility is favorable outcome / total possible outcomes.
Step-by-step explanation:
So this means:
Favorable outcomes: 3 (Pencils)
Total possible outcomes: 12 (3 + 5 + 4)
3 / 12 = 0.25

Answer:
[tex]-10x + 4 y + 27[/tex]
Step-by-step explanation:
Answer: -10x+4y+27
Step-by-step explanation: first, combine the like terms
20 + 7= 27
-9x-x=-10x
4y stays the same so, if simplified this equals
-10x+2y+27

Answer:
x = 58.5 m
Step-by-step explanation:
Let us use sine law to find the length of the yellow cable. Note that a cable of length 64 m is directly opposite the 112° angle and the 58° angle is directly opposite the unknown cable length. We can the set up our sine law as follows:
[tex] \frac{x}{ \sin(58) } = \frac{64 \: m}{ \sin(112) } [/tex]
Solving for x,
[tex]x = \frac{ \sin(58) }{ \sin(112) } \times (64 \: m) = 58.5 \: m[/tex]

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

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

Step-by-step explanation:
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
There are 15 kittens at the animal shelter, and i want to adopt 2 of them. How many different pairs of 2 are there?
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
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 =
