(2/3 + 3/4) × (3/6 + 4/9)
Answer:
289/216
Step-by-step explanation:
add the parentheses first
(2/3+3/4)×(3/6+4/9)=
17/12×17/18
then multiply
17/12×17/18=
286/216
2/3 + 3/4
= 2 × 4/3 × 4 + 3 × 3/4 × 3
= 8/12 + 9/12
= 8 + 9/12
= 17/12
For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common denominator. The common denominator you can calculate as the least common multiple of both denominators - LCM(3, 4) = 12. In practice, it is enough to find the common denominator by multiplying the denominators: 3 × 4 = 12. In the next intermediate step, the fraction result cannot be further simplified by canceling.
Add: 3/6 + 4/9
= 3 × 3/6 × 3 + 4 × 2/9 × 2
= 9/18 + 8/18
= 9 + 8/18
= 17/18
For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common denominator. The common denominator you can calculate as the least common multiple of both denominators - LCM(6, 9) = 18. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 6 × 9 = 54. In the next intermediate step, the fraction result cannot be further simplified by canceling.
2 = 17/12 × 17/18
= 17 × 17/12 × 18
= 289/216
Multiply both numerators and denominators. Result fraction keep to lowest possible denominator GCD(289, 216) = 1. In the next intermediate step, the fraction result cannot be further simplified by canceling.

Let f(t) represent the temperature of a turkey baking in an oven as a function of time [] in the oven (in minutes). This means time is the independent variable and temperature of the turkey t) is the dependent variable. The turkey was in the oven for 360 minutes and then removed. Note that when something is baked in an over, the temperature of the oven stays constant
1. Describe the rate of change pattern over each interval of the graph listed below.
a) 0
b) 345
c) t > 360
2. Explain what is happening in each interval of your graph in terms of the turkey and its temperature, using complete sentences
3. Let's say that the turkey sat on the counter for an additional hour (beyond the 390 minutes) and its temperature cooled to 80 degrees. Write that value in function notation
Answer:
Since x (independent) is time and y (dependent) is temperature;
F(0) =50 means; at the beginning which is 0 minutes, the temperature is 50F
f(120)>f(60) means the temperature after 120 min is bigger than the temperate after 60 min.
f(360) = f(345) means the temperature after 360 min and 345 min are the same
f(390) < f(360) means the temperate after 390 min is less than the temperature after 360 min
Step-by-step explanation:
Answer:
Since x (independent) is time and y (dependent) is temperature;
F(0) =50 means; at the beginning which is 0 minutes, the temperature is 50F
f(120)>f(60) means the temperature after 120 min is bigger than the temperate after 60 min.
f(360) = f(345) means the temperature after 360 min and 345 min are the same
f(390) < f(360) means the temperate after 390 min is less than the temperature after 360 min

The diagonal of one side of a rhombus are of equal length. Find the measure of angles of the rhombus.
Consider ABCD is a rhombus
We know that
All sides are equal in rhombus
=> AB=BC=CD=DA
and AC and BD are digonals
Given that
Diagonal and the side of the rhombus are equal.
=> AB = BC = CD = DA = AC
Diagonal AC divides the rhombus into two triangles .
They are ∆ BAC and ∆ DAC
In triangle BAC
BA=BC=AC,(Given)
=> < BAC=<ABC= < ACB =60°………(1)
Similarly in ∆DAC ,
DA=DC=AC
=><DAC=<ACD=<ADC=60°……….(2)
From (1) and (2)
<A=<BAC+< DAC=60°+60°=120°
and
< B= < ABC = 60°.
and
<C=<ACB+<ACD=60°+60°=120°
and
< D =<ADC=60°
Therefore, <A = 120° , <B = 60° ,<C = 120° ,<D = 60°
Answer:-
The measures of the all angles in the rhombus are 120° , 60° ,120° and 60°
Used formulae:-
all sides in a rhombus are equal

can someone explain scientific notation please it’s so confusing.
Let's say we had the massive number
6,230,000,000
which we can shorten it to saying "6.23 billion" and that allows us to drop all the extra zeros at the end.
When writing it in scientific notation, we would say [tex]6.23 \times 10^9[/tex] and the [tex]\times 10^9[/tex] portion indicates "times ten to the ninth power". This is the place holder for "billion". It means we'll move the decimal point 9 spots to the right to go from 6.23 back to the original massive number shown above.
In short, scientific notation allows us to represent really large numbers in a compact way. It's useful to be able to communicate to a friend about whatever number you're referring to. One application is trying to find vast distances in outer space which tend to be very larger numbers. There are many other applications for scientific notation.

The equation y = 0.29x + 58 models the cost y of renting a car if the car is driven x
miles.
According to the model, what is the best estimate of the cost for renting a car if you
plan to drive 619 miles? Please round your answer to the nearest dollar.
Include answer and units
Answer:
y = $238
Step-by-step explanation:
Given the equation, y = 0.29x + 58
Where:
y = total cost of renting a car
x = number of miles driven
58 = initial cost or amount.
To find the estimated cost for renting a car if you plan on driving for 619 miles, substitute 619 as the value of x into the equation:
y = 0.29(619) + 58
y = 179.51 + 58
y = 237.51 or 238
Therefore, the estimated total cost for driving 619 miles is $238.
