Step-by-step explanation:
Candice leaves on a trip driving at 25 miles per hour. Four hours later, her sister Liz starts from the same location driving at 50 miles per hour. How long after Liz leaves home will she catch up to Candice?
9 hours
4 hours
7 hours
8 hours
Answer:
The time that Liz will take to catch up with Candice after Liz starts is:
4 hours.Step-by-step explanation:
We're gonna use the formula:
Distance = Speed * TimeAnd we'll give a variable for each driven distance:
C= Candice's driven distance. L= Liz's driven distance.Now, Liz begins when four hours had passed, then, from the beginning of this exercise Candice's distance is:
25 miles / hour * 4 hours = 100 milesCandice had a 100 miles lead when Liz started, so, the distances 1 hour after Liz began were:
C= 25 miles / hour * 1 hour + 100 miles = 125 miles. L= 50 miles / hour * 1 hour = 50 miles.When two hours have passed:
C= 25 miles / hour * 2 hour + 100 miles = 150 miles. L= 50 miles / hour * 2 hour = 100 miles.When three hours have passed:
C= 25 miles / hour * 3 hour + 100 miles = 175 miles. L= 50 miles / hour * 3 hour = 150 miles.And, when four hours have passed:
C= 25 miles / hour * 4 hour + 100 miles = 200 miles. L= 50 miles / hour * 4 hour = 200 miles.Then, Liz will catch up with Candice 4 hours after she leaves because after that time the distance traveled is the same for them.

Find the least counting number which when divided by 5 gives the remainder of 1 and when divided by 12 gives us the remainder of 3
Answer:
51
Step-by-step explanation:
Let x be the number
When x divided by 5 then it gives remainder 1 and when divided by 12 gives remainder 3.
We have to the value of x.
Using Euclid's algorithm
[tex]a=bq+r[/tex]
Where [tex]0\leq r<b[/tex]
[tex]x=5q+1[/tex]
[tex]x=12p+3[/tex]
[tex]5q+1=12p+3[/tex]
[tex]5q-12p=3-1[/tex]
[tex]5q-12p=2[/tex]...(1)
When q=10 and p=4
Then,
[tex]5(10)-12(4)=50-48=2[/tex]
q=10 and p=4 satisfied the equation (1)
Substitute q=10
[tex]x=5(10)+1=51[/tex]
Hence,51 is the least counting number which when divided by 5 gives the remainder of 1 and when divided by 12 gives us the remainder of 3.

Write a quadratic equation given the roots -1/3 and 5, show your work
[tex] \boxed{(x - a)(x - b) = 0}[/tex]
The equation above is the intercept form. Both a-term and b-term are the roots of equation.
[tex]x = - \frac{1}{3} \\ x = 5[/tex]
These are the roots of equation. Therefore we substitute a = - 1/3 and b = 5 in the equation.
[tex](x + \frac{1}{3} )(x - 5) = 0[/tex]
Here we can convert the expression x+1/3 to this.
[tex]x + \frac{1}{3} = 0 \\ 3x + 1 = 0[/tex]
Rewrite the equation.
[tex](3x + 1)(x - 5) = 0[/tex]
Simplify by multiplying both expressions.
[tex]3 {x}^{2} - 15x + x - 5 = 0 \\ 3 {x}^{2} - 14x - 5 = 0[/tex]
Answer Check
Substitute the given roots in the equation.
[tex]3 {(5)}^{2} - 14(5) - 5 = 0 \\ 75 - 70 - 5 = 0 \\ 75 - 75 = 0 \\ 0 = 0[/tex]
[tex]3( - \frac{1}{3} )^{2} - 14( - \frac{1}{3}) - 5 = 0 \\ 3( \frac{1}{9} ) + \frac{14}{3} - 5 = 0 \\ \frac{1}{3} + \frac{14}{3} - \frac{15}{3} = 0 \\ \frac{15}{3} - \frac{15}{3} = 0 \\ 0 = 0[/tex]
The equation is true for both roots.
Answer
[tex] \large \boxed {3 {x}^{2} - 14x - 5 = 0}[/tex]

Find the HCF of 58 and 70 using the
division method.
Answer:
Find the prime factorization of 58. 58 = 2 × 29.
Find the prime factorization of 70. 70 = 2 × 5 × 7.
To find the GCF, multiply all the prime factors common to both numbers: Therefore, GCF = 2

what is the value of y in the equation if x = 5
=》2x + 6y = 22
Step-by-step explanation:
We have 2x + 6y = 22.
When x = 5,
=> 2(5) + 6y = 22
=> 10 + 6y = 22
=> 6y = 12
=> y = 2.
Hence y = 2 when x = 5.

Container A is cylinder with a radius of 10 units and a height of 10 units. A right cone has been carved from its base and has a height of 10 units. Container B has the same radius as container A. Which statement derives the formula to find the volume of container A?
container A is a right cylinder that has had a right cone subtracted from its base, container B is half of a sphere
1 over 3π(102)(10) − π (102)(10)
2[1 over 3π(102)(10) − π(102)(10)]
π(102)(10) − 1 over 3π(102)(10)
2[π(102)(10) − 1 over 3π(102)(10)]
Answer: π(10^2)(10) − 1/3π(10^2)(10)
Step-by-step explanation:
Container A is a cylinder so the equation is π(r^2)(h)
Container B is a right cone so that equation is 1/3π(r^2)(h)
You would plug in the numbers and then subtract A from B
The formula to find volume of cylinder of container A is πr²h - 1/3π²h.
Thus Option (c) is correct
What is volume cylinder?The volume of cylinder is "the density of the cylinder which signifies the amount of material the cylinder can carry".
According to the question,
Container A is "cylinder with a cylinder of radius of 10 units and has height is 10 units. Container B is cylinder with a cylinder of radius of 10 units and has height is 10 units. A right cone has base and has a height 10 units.
In order to find volume of container A only if subtract volume of cone from volume of cylinder
Formula for volume of cylinder = πr²h
Formula for volume of cone = 1/3π²h
Formula for volume of container A = πr²h - 1/3π²h
Hence, the formula to find volume of cylinder of container A is πr²h - 1/3π²h. Thus, Option (c) is correct
