Answer:
a = 2, b = 4, c = 8
Step-by-step explanation:
Let:
First (smallest) number = a
Second number = b
Third number(Largest) = c
The sum of three numbers is 14.
a + b + c = 14...... Equation 1
The largest number is 4 times the smallest number.
c = 4a.... Equation 2
The sum of the smallest and twice the largest is 18.
a + 2c = 18........ Equation 3
We substitute Equation 2 in Equation 3
to solve for a
a + 2(4a) = 18
a + 8a = 18
9a = 18
a = 18/9
a = 2
Hence, the smallest number = 2
We find c
c = 4a.... Equation 2
c = 4(2)
c = 8
The largest number is 8
We find b
a + b + c = 14...... Equation 1
2 + b + 8 = 14
b + 10 = 14
b = 14 - 10
b = 4
What are all three numbers?
a = 2, b = 4, c = 8
A cell phone tower and a fence are on the same property. the fence is 8 feet tall and has a shadow that measures 14.5 feet. the shadow of the cell phone tower measures 72.5 feet . how tall is the cell phone tower ?
Answer:
40 feets
Step-by-step explanation:
Given that:
Height of fence = 8 feets
Shadow of fence = 14.5 feets
Shadow of cell phone tower = 72.5 feets
Height of cell phone tower = x
Height of fence = shadow of fence
Height of tower = shadow of tower
8 feets= 14.5 feets
x feets = 72.5
Cross multiply :
(14.5 * x) = (72.5 * 8)
14.5x = 580 feets
x = 580/14.5
x = 40 feets
Hence, the height of the cell phone tower is 40 feets

Answer:
Answer is 79 and 28
Step-by-step explanation:
Let two numbers be x and y.
x + y = 107. --> 1
x - y = 51 -->2
solving above equations,
2x = 158
x =79
y = 28
So far, a storm has traveled 35 miles in half an hour. If it is currently 5:00 pm and the storm is 105 miles away, what time will the storm reach you? Explain how you solved the problem.
Answer:
It will reach you at 6:30.
Step-by-step explanation:
THe storm traveled at 35 miles in half an hour. It is 105 miles away.
Divide 105 by 35 to get how many half hours it will take to rach you.
105 ÷ 35 = 3.
So, it will be 3 half hours or one hour and a half.
Add that time to the current time, which is 5:00.
It will be 6:30 when the storm reaches you.

Complete the equation that represents the total value of the nickels and p pennies
Answer:
Answers below
Step-by-step explanation:
Equation
Let's call:
p = number of pennies Janesa has in her pocket
n = number of nickels Janesa has in her pocket
She has 24 coins in total, thus:
[tex]p + n=24\qquad\qquad [1][/tex]
Since each penny is worth $0.01 and each nickel is worth $0.05, and Janesa has $1 in total:
[tex]0.01p+0.05n=1[/tex]
Multiplying by 100:
[tex]p+5n=100\qquad\qquad [2][/tex]
A. Completing the equation:
[tex]5n+p=100[/tex]
B.
From [1]:
[tex]p=24-n[/tex]
Substituting into [2]:
[tex]24-n+5n=100[/tex]
Simplifying:
[tex]24+4n=100[/tex]
Rearranging:
[tex]4n=100-24=76[/tex]
[tex]n=76 / 4= 19[/tex]
[tex]p=24-19=5[/tex]
B. There are 5 pennies in Janesa's pocket
C. Since each penny is worth $0.01, the total value of pennies is 5*$0.01=$0.05
The total value of the pennies is $0.05
D. The total value of the nickels is 19*$0.05 = $0.95
E. Jackson should say she has 19 nickels and 5 pennies
janesa has 24 coins in her pocket worth exactly $1.00. she tells her younger brother jackson that he can have the coins if he correctly guesses how many of each coin she has. she gives him the hint that there are only nickels and pennies. complete the equation that represents the total value of the nickels and p pennies 5( blank ) + p = 100 The type of coins that Janessa has = nickels and pennies.
Janessa has a total number of 24 coins
The sum of the nickels and pennies = $1.00
Let us represent the number of nickels as x
The number of pennies as y

How many ways can you arrange the word HOCKEY using only 5 letters
if each letter can only be used once?
Answer:
Total arrangement = 720
Step-by-step explanation:
Given:
Total letter n = 6
Using letter r = 5
Computation:
Total arrangement = nPr
Total arrangement = !n / !(n-r)
Total arrangement = !6 / !(6-5)
Total arrangement = 6 x 5 x 4 x 3 x 2
Total arrangement = 720

A star patterned quilt has a star with the angels shown. What is the value of x? Explain your answer.
Answer:
81°
Step-by-step explanation:
x° and 24° are interior angles of a triangle that are opposite to an exterior angle of measure 105°. According to the exterior angle theorem of a triangle, thus:
[tex] x + 24 = 105 [/tex]
Subtract 24 from both sides
[tex] x + 24 - 24 = 105 - 24 [/tex]
[tex] x = 81 [/tex]
Value of x = 81°

Step-by-step explanation:
8 coins are tossed simultaneously, find the chance of obtaining at least six heads
Answer:
37/256
Step-by-step explanation:
We need to use the Binomial distribution here, ask me why?
because there are only two outcomes of the experiment, heads or tails, which are complementary by nature, that is to say they are mutually exclusive and if one doesn't happen the other definitely does
p(head)+p(tail) = 1
also the trials are independent of one another, that is to say that the outcome of one toss doesn't affect the outcome of any of the other seven tosses out of 8.
and I am assuming here that the coins are all unbiased, i.e. p(head)=p(tail)=0.50
Considering all of these the possibility that we will get at least 6 heads out of 8 tosses is given by
p(head=6)+p(head=7)+p(head=8)= 8C6 (0.5)^6 (0.5)^2 + 8C7 (0.5)^7 (0.5)^1 + 8C8 (0.5) ^8
The plus sign indicates OR operator, i.e. we might get 6 heads or 7 heads or 8 heads.
where the probability mass function of the bin distn is given by
nCx p^x q^(n-x)
n= total number of trials
x= no. of success (in our case no of heads)
n-x = no of failures (no of tails in this example)
p= probability of success (p(heads)=0.5)
q= probability of failure (is equivalent of 1-p)
