What is the value of n in centimeters?
A. 9 cm
B. 4.5 cm
C. 3 cm
D. 12 cm
Answer:
A, 4.5
Step-by-step explanation:
6^2 + n^2 = 7.25^2
36 + n^2 = 56.25
56.25 - 36 = 20.25
√20.25 = 4.5
Determine the volume of a cylinder with 251.20cm2 lateral area and 78.50cm2 base area
Answer:
Answer is 628 cm^3
Step-by-step explanation:
using base area lets find radius
base area=pie*(r)^2
78.50=3.14*r^2
78.50/3.14=r^2
25=r^2
5=r
now using lateral area lets find height
lateral area=2*pie*r*h
251.20=2*3.14*5*h
251.20=31.4*h
251.20/31.4=h
8=h
volume of cylinder=pie*(r)^2*h
=3.14*(5)^2*8
3.14*25*8
=628 cm^3
Below. What is m∠1?
m∠1 =
Answer:
m∠1 = 70°
Step-by-step explanation:
Step 1
Sum of angles on a straight line = 180°
Hence:
180° - 101°
= 79°
Sum of interior angles in a triangle = 180°
Therefore,
m∠1 = 180° - (79 ° + 31°)
m∠1 = 180° - 110°
m∠1 = 70°

Below. What is m∠1?
m∠1 =
Answer:
m∠1 = 70°
Step-by-step explanation:
Step 1
Sum of angles on a straight line = 180°
Hence:
180° - 101°
= 79°
Sum of interior angles in a triangle = 180°
Therefore,
m∠1 = 180° - (79 ° + 31°)
m∠1 = 180° - 110°
m∠1 = 70°

How much does 5 packets of fries cost?
Select one
a. £6.40
b. £6.00

Answer:
C
Step-by-step explanation:
First, divide £4.20 by 3 to get the price for 1 packet.
4.20/3 = 1.4
5 packets is 5 times that, so multiply 1.4 times 5. You get 7. So 5 packets costs £7.00

find the measure of the angle indicated for each trapezoid
Answer:
The trapezoid is a quadrilateral. The 4 angles of a quadrilateral all equal to 360 degrees. Now you know that this is an isosceles trapezoid since the two sides are congruent. [360-(110*2)] / 2= [360-220] / 2= 140/2=70. So the answer is 70 degrees.

The population of Florida in 2000 was 15,982,378 and the land area was 54,252 square miles. The population increased 26.8% by 2015. To the nearest whole number, how much did the population density, in people per square mile, increase from 2000 to 2015?
Answer: See explanation
Step-by-step explanation:
Population in 2000 = 15,982,378
Land area = 54,252 square miles
The population density in 2000 will be:
= Population / Land area
= 15982378 / 54,252
= 294.60people per square miles
Since the population increased by 26.8% in 2015, the population in 2015 will be:
= 15,982,378 × (100% + 26.8%)
= 15,982,378 × 126.8%
= 15,982,378 × 1.268
= 20,265655
The population density in 2015 will be:
= Population / Land area
= 20,265655 / 54,252
= 373.55 people per square miles
The increase in population density from 2000 to 2015 will be:
= 373.55 - 294.60
= 78.95

The lateral area of a regular pentagonal pyramid is 75 square inches and the slant height is 10 inches. Find the length of each side of the base.
A) 15 in.
B) 14 in.
C) 7.5 in.
D) 3 in
The length of each side of the base is 3 inches. Thus, the correct option is D.
What is the pyramid?In terms of geometry, a pyramid is a polygon that is created by joining an apex and a polygonal base. A triangle known as a lateral face is formed by each base edge and apex. If the base of the pyramid is a rectangle then the pyramid is known as a rectangular pyramid.
The lateral area of a regular pentagonal pyramid is 75 square inches and the slant height is 10 inches.
The length of each side of the base is calculated as,
75 = 5 x 1/2 x a x 10
75 = 25a
a = 3 inches
Thus, the correct option is D.
