Answer:
c.14
Step-by-step explanation:
Answer:
14
Step-by-step explanation:
To get the Greates Common Factor (GCF) of 238 and 462 we need to factor each value first and then we choose all the copies of factors and multiply them:
238: 2 7
462: 2 3 7
GCF: 2 7
The Greates Common Factor (GCF) is: 2 x 7 = 14

Jackson’s backpack weighs 734 pounds. After he adds food and water to his backpack, it weighs 1134 pounds. If the water weighs 134 pounds, how much does the food weigh?
Answer: 266 lbs.
Step-by-step explanation:
First, you subtract 734 from 1134 to get 400. Then, you subtract the number of pounds the water weighs from how much the food and water weighs. So you basically do 400 - 134 to get 266.

d. Using the diagram at the right,
determine the measure of AEC,
DEB, and CEB if x = 23°. Show
all your work.
Answer:
AEC=BED=157°
Step-by-step explanation:
AEC + CEB + BED + x = 360°
since CEB and x are vertical angles, they are equal.
Also, AEC = BED (same reason)
therefore,
2AEC+ 23° + 23° = 360°
2AEC + 46° = 360°
2AEC = 360° - 46°
2AEC = 314°
AEC = 157°
BED also = 157°

A spinner is divided into 12 identical sectors and labeled 1 through 12. How many spins are expected for a multiple of 5 to be spun 22 times? Select from the drop-down menu to correctly complete the sentence. The spinner is expected to have to spin approximately Choose... times for a multiple of 5 to be spun 22 times
1. 68
2. 88
3. 110
4. 132
Using the binomial distribution, it is found that the spinner is expected to have to spin approximately 132 times for a multiple of 5 to be spun 22 times, hence option 4 is correct.
What is the binomial probability distribution?It is the probability of exactly x successes on n repeated trials, with p probability of a success on each trial.
The expected number of trials until q successes is:
[tex]E_f(X) = \frac{q}{p}[/tex]
In this problem:
We want 22 successes, hence q = 22.2 out of 12 sections(5 and 10) are multiples of 5, hence p = 1/6.Then:
[tex]E_f(X) = \frac{q}{p} = \frac{22}{\frac{1}{6}} = 22 \times 6 = 132[/tex]
Hence option 4 is correct.

A cube with a volume of 75 cm³ is dilated by a factor of 5. What is the volume of the dilated cube? Enter your answer in the box. Cm³.
Using the concept of dilation the volume of the dilated cube when dilated by a factor of 5 is 9375 cm³.
What is dilation?Dilation means the changing of the size of the object without changing the shape. The size of the object may be increased or decreased based on the scale factor.
Given
A cube with a volume of 75 cm³ is dilated by a factor of 5.
The edge of the cube before dilation
Edge³ = 75
Edge = 4.217
The edge after dilation will be
Edge = 5 x 4.217
Edge = 21.08
The volume of the dilate cube will be
Volume = ( Dilated Edge)³
Volume = 9375
The volume of the dilated cube is 9375 cm³.

A wire is attached 35 feet above the ground to a telephone pole. The wire makes an angle of 45° with the ground, as shown below. What is the length of the wire?
Answer:
The length of the wire will be 44.83 feet.
Step-by-step explanation:
From the information given, the wire is attached from the top of a 30 foot telephone pole to a stake in the ground. if the angle formed by the wire and the pole is 48°.
Therefore, the length of the wire will be:
cos 48° = 30/x
x = 30/cos 48°
x = 44.83
The length is 44.83 feet.
Length of the wire is equals to 35√2 feet.
What is angle of elevation?"Angle of elevation is defined as the angle between the horizontal plane and the line drawn through the point of observation."
Formula used
sinθ = (Opposite side) / Hypotenuse
According to the question,
Given,
Length of the pole = 35feet
Angle of elevation = 45°
Length of the wire = Hypotenuse
'l' represents the length of the wire
Substitute the value in the formula we get,
sin 45° = (35 / l )
⇒ (1 / √2) = (35 / l )
⇒l = 35√2 feet
Hence, length of the wire is equals to 35√2 feet.

The point StartRoot x EndRoot is plotted on the number line. A number line going from 9. 8 to 10. 7. StartRoot x EndRoot is plotted slightly to the left of 10. 2. What whole number best approximates the value of x? 100 102 103 104.
Function assigns the value of one set to another. The whole number that best approximates the value of x is 10.
What is Function?A function assigns the value of each element of one set to the other specific element of another set.
As it is given that the point √x is plotted on the number line. therefore, the value of x is in square root. Now, in order to get a whole number out of this point function, we need the value of x should be such that when it goes through the function the outcome must be a whole number. therefore, let's substitute the value of x in the function,
A.) 100
[tex]\sqrt{x} = \sqrt{100} = 10[/tex]
B.) 102
[tex]\sqrt{x} = \sqrt{102} = 10.099[/tex]
C.) 103
[tex]\sqrt{x} = \sqrt{103} = 10.149[/tex]
D.) 104
[tex]\sqrt{x} = \sqrt{104} = 10.198[/tex]
As we can see, when the value of x is 100, only then the outcome of the point function is a whole number.
Hence, the whole number that best approximates the value of x is 10.

Nancy and Elsa like to ride bikes. The equation m=12h represents the approximate number of miles m Nancy bikes in h hours. The equation m=9h represents the approximate number of miles m Elsa bikes in h hours. How much longer will it take Elsa to bike 72 miles than Nancy?
Answer:
2 hours
Step-by-step explanation:
substitute m = 72 into both equations and solve for h
72 = 12h ( divide both sides by 12 )
6 = h
Takes Nancy 6 hours to cycle 72 miles
72 = 9h ( divide both sides by 9 )
8 = h
Takes Elsa 8 hours to cycle 72 miles
Elsa takes 2 hours longer than Nancy to cycle 72 miles
Answer:
2
Step-by-step explanation:
Answer:
2 hours
Step-by-step explanation:
substitute m = 72 into both equations and solve for h
72 = 12h ( divide both sides by 12 )
6 = h
Takes Nancy 6 hours to cycle 72 miles
72 = 9h ( divide both sides by 9 )
