Three consecutive even numbers are such that the sum of four times the smallest and twice the largest exceeds three times the second by 2006. What is the sum of the digits of the smallest number
Answer:
the sum of the digits of the smallest number 668 = 6+6+8 = 20
Step-by-step explanation:
3 consecutive even number: x, x+2, x+4
4x + 2*(x+4) = 3*(x+2) + 2006
6x + 8 = 3x + 6 + 2006 = 3x + 2012
6x - 3x = 2012 - 8 = 2004
3x = 2004
x = 668
the sum of the digits of the smallest number = 6+6+8 = 20

Write the equation in standard form that has a slope of -5/2 and a y-intercept of -2
Answer:
y = -5/2 x - 2
Step-by-step explanation:
The standard form of equation of a line is expressed as;
y = mx+c
m is the slope
c is the yintercept
Given
m = -5/2
c = -2
Substotute into the exoression above
y = -5/2 x + (-2)
y = -5/2 x - 2
Hence the equation in standard form is y = -5/2 x - 2

Monica deposit 300 into a savings account that pays a simple interest rate of 4.3% call deposit 400 and into the savings account that pays simple interest rate of 4.2% Monica says she warren more interest in one year because her interest rate is higher is she correct
Answer:
No
Step-by-step explanation:
MONICA:
Principal, p = 300
Simple interest, r = 4.3% = 0.043
CALL:
Principal, p = 400
Simple interest, r = 4.2% = 0.042
Amount, A received by each after one year :
Recall:
A = p(1 + rt) ; time, t = 1 year
MONICA:
A = 300(1 + 0.043(1))
A = 312.9
CALL = 400(1 + 0.042(1))
A = 416.8
Monica is incorrect, this is because amount earned is not only dependent on the interest rate but also the number of period and the initial or principal amount deposited.

Step-by-step explanation:
Under his cell phone plan, evan pays a flat cost of $57.50 per month and $3 per gigabyte. he wants to keep his bill at 62.90 per month. write and solve an equation which can be used to determine g, the number of gigabytes of data evan can use while staying within his budget.
Answer:
He can use 1.8 gigabytes of data
Step-by-step explanation:
The equation would be:
62.90 = 57.50 + 3g
Solve:
Subtract 57.50 from both sides, which gives you:
5.4 = 3g
g = 1.8
The number of gigabytes of data that Evan can use while staying within his budget is 1.8 gigabytes.
Based on the information given, the equation to solve the question will be:
57.50 + (3 × g) = 62.90
57.50 + 3g = 62.90
Collect like terms
3g = 62.90 - 57.50
3g = 5.40
Divide both side by 3
3g/3 = 5.40/3
g = 1.80
The number of gigabytes of data that Evan can use while staying within his budget is 1.8 gigabytes.

A zookeeper is 6 1/4 feet tall. A young giraffe in his care is 9 3/8 feet tall how many times as tall as the zookeeper is the giraffe?
Answer: The giraffe is 1.5 times tall as the zookeeper.
Step-by-step explanation:
Given: Height of Giraffe = [tex]9\dfrac38\ feet =\dfrac{72+3}{8}\ feet =\dfrac{75}{8}\ feet[/tex]
Height of zookeeper= [tex]6\dfrac14\ feet =\dfrac{24+1}{4}\ feet =\dfrac{25}{4}\ feet[/tex]
Let n = number of times the giraffe is tall as the zookeeper.
[tex]n=\dfrac{\dfrac{75}{8}}{\dfrac{25}{4}}=\dfrac{75\times4}{25\times8} = 1.5[/tex]
Hence, the giraffe is 1.5 times tall as the zookeeper.

How did you compute sums of dollar amounts that were not whole numbers? For example, how did you compute the sum of$5.89 and$1.45? Use this example to explain your strategy. 2.
Answer:
$7.34
Step-by-step explanation:
To compute sum of dollars that are not whole numbers. Using the sum of$5.89 and$1.45 as an illustration :
$5.89 + $1.45
Taking the whole numbers first:
$5 + $1 = $6
Take the sum of the decimals :
$0.89 + $0.45 = $1.34
Sum initial whole + whole of sum of decimal
$6 + $1 = $7
Remaining decimal : $1.34 - $1 = $0.34
$7 + $0.34 = $7.34
Answer:
$7.34

How many times can Henry expect to roll a 4 if he rolls a fair number cube 120 times?
Henry can expect to roll a 4 about 20 times if he rolls a fair number cube 120 times.
What is Probability?It is a branch of mathematics that deals with the occurrence of a random event.
The probability of rolling a 4 on any given roll is 1/6.
The expected number of times that Henry can roll a 4 is equal to the probability of rolling a 4 on a single roll multiplied by the number of rolls.
Expected number of times to roll a 4 = Probability of rolling a 4 on a single roll × Number of rolls
Expected number of times to roll a 4 = (1/6) × 120
Expected number of times to roll a 4 = 20
Therefore, Henry can expect to roll a 4 about 20 times if he rolls a fair number cube 120 times.
