Find the missing length.
a
2.1 cm
2.9 cm
I NEED HELPPPP PLSSSS ITS FOR A MASTERY TEST PLSSSS HELPPPP
Answers
Answer:
a = 2
Step-by-step explanation:
To find the missing length we can use the Pythagorean theorem. Also, because it's a right triangle it makes it the perfect candidate!
The Pythagorean Theorem states:
a^2 + b^2 = c^2
Next, we substitute the letters with our given numbers (keep in mind that c is the hypotenuse which is the side facing the right angle)
a^2 + 2.1^2 = 2.9^2
Finally, we solve our equation (hint: use the calculator if needed)
a^2 = 4 (your answer is not final yet. You have to take the square root of both numbers)
a = 2 (Now that's the final answer!)

If Brenda decides to use milliliters and leaders in terms room instead and each person at the party will drink about 750 mL after 32 people and they each drink about 750 mL how many liters of punch open does mom need to buy?
Answers
Answer:
24 litres
Step-by-step explanation:
Given that :
Number of people present at party = 32
Volume of drink consumed by each person in mL = 750 mL
To consumption in mL:
Number of people * volume consumed by each
32 * 750 mL
24000 mL
24000 mL to L
1000 mL = 1 L
24000 mL = (24000/ 1000)L
= 24 L

Step-by-step explanation:
The sign shows that any number that is equal to, or more than, 36 is a valid answer. It can't be 3 because 3 x 9 is 27, and 27 is less than 36, so that wouldn't be true. 4 x 9 is 36, and 36 = 36, so that would be true, and obvoiusly all the other numbers that are over 4, when multiplied by 9, will equal more than 36, so they are all correct, except for the 3 and none answers. I hope this helps you out :)

The diameter of a circle is 0.82 inches. What is the approximate area of the circle?
Answers
Answer:
.53
Step-by-step explanation:
your diameter is .82,so divide it by two to get your radius
.82 / 2 = .41
A = [tex]\pi[/tex] r ^2
A = [tex]\pi[/tex] .41 ^2
A = .53
Answer:
0.53

Answer:
Step-by-step explanation:
Area of square = side * side

Area of triangle = [tex]\frac{1}{2}*base*height\\[/tex]
[tex]= \frac{1}{2}*4*2\\\\= 4 sq.ft[/tex]
Area of the figure = area of square + area of triangle
= 16 + 4
= 20 sq.ft
work out the circumference of a cirlce with a diameter of 1.8m
Answers
Answer:
5.56 m
Step-by-step explanation:
Circumference = 2πr
r is the radius, however the diameter is given. The radius is half the diameter. So the radius is:
1.8 ÷ 2 = 0.9
Circumference = 2 × π × 0.9
= 5.56 m ( in 3 significant figures )

2.a sector with angle 45 degrees has ab arc length 44cm find it radius and perimeter speratly
pls answer asap i will give u the brainliest
Answers
Step-by-step explanation:
Number 1
Circumference = 88cm
Circumference = 2πr
2πr = 88
πr = 88/2
πr = 44
22r/7 = 44
22r = (44 × 7)
r = (44 × 7)/22
r = 2 × 7
r = 14cm
Number 2
Length of arc = 44cm
Angle = 45°
L = ∅/360 × 2πr
44 = 45/360 × 2πr
44 = ⅛ × 2πr
44 = ¼ × πr
πr = 44 × 4
22r/7 = (44 × 4)
22r = (44 × 4 × 7)
r = (44 × 4 × 7)/22
r = 2 × 4 × 7
r = 2 × 28
r = 56cm
Perimeter = L + 2r
P = 44cm + 2(56cm)
P = 44cm + 112cm
P = 156cm
