Diego is thinking of two positive numbers, if we triple the first number and double the second number the sum is 34. Diego then says, "if we take half of the first of the first number and double the second number, the sum is 34. What are Diego’s two numbers?
Answer:
1st number: 0
2nd number: 17
Step-by-step explanation:
3x+2y=34 x is the first number, y is the second.
1/2x+2y=34 multiply each number by two to get rid of the integer by the variable x.
x+4y=68 solve for x.
x=68-4y add this into the first equation to solve for variable y.
3(68-4y)+2y=34 solve for y.
204-10y=34
-10y= -170
y=17
now to solve for x
x= 68-4(17)
x= 0

Convert the following repeating decimal to a fraction in simplest form.
.72
Answer:
The real answer is 8/11
Step-by-step explanation:
The fractional value of 0.72 is 18/25.
What is Decimal?A decimal is a number with a whole and a fractional part. Decimal numbers are between integers and represent numerical value for whole plus some fraction of a whole.
A decimal number comprises two parts: a whole number component and a fractional component. The decimal place value system is the same as the whole number value system for the whole component of a decimal number.
Given:
We have the decimal number 0.72.
Now, we can remove the decimal and put the number of zeroes in the denominator.
So, 0.72
= 72/100
Now, simplifying the fraction as
= 36/ 50
= 18/25
Now put decimal point ahead of two number from the numerator.
So, 37/100 = 0.37
So, the decimal is 0.37.

express 2.65 as a mixed number in the lowest terms
Answer:
2 13/20
Step-by-step explanation:
Answer:
2 13/20
Step-by-step explanation:
we can split up 2.65 into a whole number and a decimal
2.65
= 2 + 0.65 (note that 0.65 = 65/100)
= 2 + 65/100
= 2 65/100 (we can see that both numerator and denominator are multiples of 5, hence we can try to simply by dividing both numerator and denominator by 5)
= 2 (65÷5) / (100÷5)
= 2 13/20 (answer)

Meg is a veterinarian. I. Given week , 50% of the 16 dogs she saw were boxers . Steve is also a veterinarian. In the same week , 7 of the 35 dogs he saw this week were boxers. Each wants to know the record the part , the whole and the percent. Does meg need to find the part the whole or the percent
In this situation, Meg will need to find the whole because she already has the part and the percentage.
What is a whole?In mathematics, a whole represents the total number of items that are analyzed, in this case, the total number of dogs.
What is the part?The part refers to a number that is usually lower than the whole and describes specific characteristics. For example, in a classroom of 30 kids, 20 like to play basketball. Then 20 is the part.
What is the percentage?The percentage is the number followed by the symbol % and represents the relationship between the part and the whole. In this case, the percentage of boxers is related to the number of total dogs.
Based on this, Meg already has the percentage (50%), and the part (16), therefore, she needs to find the whole or the total number of dogs, in this case, 32.

If an object is projected upward with an initial velocity of 48 ft per second from a height h of 64 ft, then its height t seconds after it is projected is defined by the equation f(t) = -16(t) with superscript (2) + 48t + 64. How many seconds after it is projected will it hit the ground?
Answer:
4 seconds
Step-by-step explanation:
Given that :
Height of a projected object is modeled by:
f(t) = - 16t² + 48t + 64
t = height
How many seconds after projection will it hit the ground ;
When the projectile hits the ground ; t = 0
f(t) = - 16t² + 48t + 64
f(t) = 0
- 16t² + 48t + 64 = 0
Divide through by - 16
t² - 3t - 4 = 0
t² - 4t + t - 4 =0
t(t - 4) +1(t - 4) = 0
(t +1) = 0 or (t - 4) = 0
t = - 1 or t = 4
t can't be negative ;
Hence, the projectile will hit the ground after 4 seconds

what is the sum of zeros of the equation (m-10)(6m-1)=0. Ancwer your question as a fraction
PLSSS SOMEONE ANCWEE THISS BEGGINGG.
Answer:
The sum of zeros is [tex]\frac{61}{6}[/tex]
Step-by-step explanation:
The Rule of Zero Product
The rule of zero product states that the product of two nonzero elements is nonzero. It can be written as the following assertion:
If a.b=0, then a=0 or b=0
The equation
(m-10)(6m-1)=0
can be solved by applying the mentioned rule:
[tex]m-10=0 \ \ \Rightarrow m=10[/tex]
[tex]6m-1=0 \ \ \Rightarrow m=1/6[/tex]
The sum of both solutions is:
[tex]\displaystyle 10+\frac{1}{6}=\frac{61}{6}[/tex]
The sum of zeros is [tex]\mathbf{\frac{61}{6}}[/tex]

Step-by-step explanation:
A group of n friends is going to drive together to a big city to have lunch, visit a museum, and have dinner. They expect to spend $15 for gasoline, $20 for parking, $8 each for lunch, $11 each for tickets to the museum, and $12 each for dinner. The expression below represents the total number of dollars they expect to spend. 15 +20 + 8n +11n +12n The expression can be simplified as 35 +31n. Which statement explains the meaning of this simplified expression?
A. They expect to spend $66 each, not including gasoline and parking.
B. They expect to spend $31 each, plus an extra $35 for gasoline and parking.
C. They expect to spend $66 each, including gasoline and parking.
D. They expect to spend $35 each, plus an extra $31 for gasoline and parking.
Answer:
Option (B)
Step-by-step explanation:
Group of 'n' friends is going to drive together.
Expected expenditure on gasoline and parking = $(15 + 20) = $35
Expected expenditure for lunch, tickets for museum and dinner
= (8 + 11 + 12) × n
= 31n
Expression representing total expenditure = 35 + 31n
This expression shows the expected expenditure on each friend = $31
Plus an extra expense on gasoline and parking = $35
Therefore, Option (B) is the correct option.
