Answer:
18 minutes earlier
Step-by-step explanation:
Given
[tex]Distance =119km[/tex]
[tex]Speed\ 1 = 70km/h[/tex]
[tex]Speed\ 2 = 85km/h[/tex]
Required
Determine how much sooner if traveled at speed 2 instead of speed 1
Speed is calculated as:
[tex]Speed = \frac{Distance}{Time}[/tex]
Make Time the subject
[tex]Time= \frac{Distance}{Speed }[/tex]
For Speed 1
[tex]Time= \frac{119km}{70km/h}[/tex]
[tex]Time= 1.7hr[/tex]
For Speed 2
[tex]Time= \frac{119km}{85km/h}[/tex]
[tex]Time= 1.4hr[/tex]
Calculate the difference
[tex]Difference = 1.7hr - 1.4hr[/tex]
[tex]Difference = 0.3hr[/tex]
Convert to minutes
[tex]Difference = 0.3*60\ min[/tex]
[tex]Difference = 18\ min[/tex]
If traveled at 85km/h, the van will arrive 18 minutes earlier

What is the volume of a cylinder, in cubic centimeters, with a height of 18 centimeters and a base diameter of 8 centimeters? Round to the nearest tenths place
Please helpppp lol
Answer:
904.8 centimeters
Step-by-step explanation:
1)identify variables
h = 18 d = 8
2)radius is half of the diameter
r = 4
3)use volume of a cylinder formula
V= PIEr^2h
4)substitute variables into formula
V=PIE(4)^2(18)
5)multiply
V= 904.778684234
6)round to the nearest tenths place
V= 904.8 centimeters

Find the measure of the angle indicated... please help
Answer:
Step-by-step explanation:
41). Measure of an external angle of a triangle is equal to the sum of teh opposite two angles.
140° = (13x + 9)° + (5x + 5)°
140 = 18x + 14
18x = 140 - 14
18x = 126
x = 7
m∠R = (13x + 9)
= 13×7 + 9
= 100°
42). m∠DCA = m∠E + m∠D
126° = (6x + 2)° + (5x + 3)°
126 = 11x + 5
11x = 126 - 5
11x = 121
x = 11
m∠D = (5x + 3)
= 5(11) + 3
= 58°
43). m∠DPQ = m∠Q + m∠R
11x + 3 = 70° + (x + 13)°
11x + 3 = x + 83
11x - x = 83 - 3
10x = 80
x = 8
m∠R = (x + 13)
= 21°
44). m∠QST = m∠T + m∠U
13 + 13x = 100 + (3x + 3)
13 + 13x = 3x + 103
13x - 3x = 103 - 13
10x = 90
x = 9
m∠U = 3x + 3
= 3(9) + 3
= 27 + 3
= 30°

Brooke has a cylinder metal tin where he keeps his coins. The radius of the base is 5.5 inches and the height is 4 inches what is the area of a vertical cross section of the cylinder through the center of the base?
Answer:
44 square inches.
Step-by-step explanation:
radius of the base = 5.5 inches
height of the cylinder = 4 inches
The shape of the vertical cross section of the cylinder through the center of the base would give a rectangle with length of 2r, and its width is the height of the cylinder.
Area of the vertical cross section = height x diameter
diameter of the cylinder = 2r
= 2 x 5.5
= 11 inches
The diameter of the cylinder is 11 inches.
Area of the vertical cross section = 4 x 11
= 44 square inches.
The area of a vertical cross section of the cylinder through the center of the base is 44 square inches.

Steve connected a wire extension that is 3/8 foot long to another wire that is 1/2 foot long. How long is the wire with the extension?
Answer:
7/8 feet
Step-by-step explanation:
In order to add two frctions you need to make their denominator the same,
3/8 can be kept as it is and we can multiply the top and bottom of 1/2 by 4 in order to ger 4/8. Now it is easier to add together,
3/8 + 4/8= 7/8

120l NaBr solute is saturated at 70 degrees. In this case option b is correct when saturated at 70 degrees.
NaBr is the chemical formula for sodium bromide. It is an inorganic compound composed of sodium (Na) and bromine (Br). Sodium bromide is a white, crystalline solid that is highly soluble in water.
In terms of its properties and uses, sodium bromide has various applications. It is commonly used in the pharmaceutical industry as a sedative and anticonvulsant drug. Sodium bromide is also used in the oil and gas industry as a completion fluid in well drilling and workover operations. Additionally, it finds applications in photography as a component of some film developers.
As a salt, sodium bromide dissociates into sodium ions (Na+) and bromide ions (Br-) when dissolved in water. These ions can participate in various chemical reactions and have different effects depending on the specific application or purpose.
