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.

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

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)

Sin = opposite/hypotenuseCos = adjacent/hypotenuseTan = opposite/adjacentsin 60° = opposite / hypotenuse
sin 60° = √3 / 2
The bottom side = √3, the hypotenuse = 2
To find the right side's value, you use Pythagorean's Theorem
a² + b² = c²a² + (√3)² = 2²a² + 3 = 4a² = 4 - 3a² = 1a = 1cos 60° = adjacent/hypotenuse

4.9t2+9t+11 models the height of the bowling pin in meters after t seconds.
About how many seconds does it take for the bowling pin to hit the ground?
Round your answer to the nearest tenth of a second.
Answer:
2.7
Step-by-step explanation:
yes i'm correct
A circus juggler on the highwire gives a bowling pin a final toss into the air with an initial velocity of 9 meters per second from a height of 11 meters. The time taken by the object to hit the ground is 2.7 seconds.
What is a quadratic equation?A quadratic equation is the second-order degree algebraic expression in a variable.
The standard form of this expression is ax² + bx + c = 0 where a. b are coefficients and x is the variable and c is a constant.
It is given that,
Initial velocity of an object, u = 9 m/s
Height, h = 11 m
The equation that models the height of the object in meters after t seconds is :
[tex]h(t)= -4.9t^2+9t+11[/tex]
We have to find the time it take for the bowling pin to hit the ground
i.e. [tex]-4.9t^2+9t+11=0[/tex]
On solving the above quadratic equation, we get the value of time t is :
t = 2.7 seconds
Hence, The time it takes to hit the ground would be 2.7 seconds.

Step-by-step explanation:
If you read it out loud, 0.4 is pronouced as "4 tenths"0.40--> 40?the ones that are equivalent are 40% and 0.4, since 40% converted into a decimal is 0.4. 4% isn't equivalent to any of the options because it would be 0.04 as a decimal.

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

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]

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

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°
