If you divide 78 by 34, will the quotient be greater than or less than 34? (Please help I'm desperate)
Answer:
The quotient will be less than 34
Step-by-step explanation:
When we talk of quotient, we are simply referring to the result of division.
Now, let’s divide 78 by 34, our answer is 2 10/34. The answer is slightly above two which in all terms is really less than 34.
So the correct answer to our question is that the quotient will be less than 34
When lava is expelled from a volcano, it temperature may vary from 700 degrees Celsius to 1200 degrees Celsius. Write an absolute value equation that represents the minimum and maximum temperatures of lava. Use x to represent the temperature.
Equation:__
Answer:
Ix - 950°C I ≤ 250°C
Step-by-step explanation:
We are told that the temperature may vary from 700 degrees Celsius to 1200 degrees Celsius.
And that this temperature is x.
This means that the minimum value of x is 700°C while maximum of x is 1200 °C
Let's find the average of the two temperature limits given:
x_avg = (700 + 1200)/2 =
x_avg = 1900/2
x_avg = 950 °C
Now let's find the distance between the average and either maximum or minimum.
d_avg = (1200 - 700)/2
d_avg = 500/2
d_avg = 250°C.
Now absolute value equation will be in the form of;
Ix - x_avgI ≤ d_avg
Thus;
Ix - 950°C I ≤ 250°C

Write an equation for the line that passes through the points (3,5) and (-2, 1).
All work must be shown for full credit. Be sure to include slope calculation.
Answer:
[tex]\displaystyle y=\frac{4}{5}x+\frac{13}{5}[/tex]
Step-by-step explanation:
The equation of the line in slope-intercept form is:
y=mx+b
Where m the slope of the line and b the y-intercept.
When two points are given, it's convenient to calculate the slope first.
Suppose we know the line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:
[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]
The points are (3,5) and (-2,1):
[tex]\displaystyle m=\frac{1-5}{-2-3}=\frac{4}{5}[/tex]
The equation is now:
[tex]\displaystyle y=\frac{4}{5}x+b[/tex]
To calculate b, we use any of the given points and solve for b. Use (3,5):
[tex]\displaystyle 5=\frac{4}{5}3+b[/tex]
Operate:
[tex]\displaystyle 5=\frac{12}{5}+b[/tex]
Solve:
[tex]\displaystyle b=5-\frac{12}{5}=\frac{13}{5}[/tex]
The required equation of the line is:
[tex]\boxed{\displaystyle y=\frac{4}{5}x+\frac{13}{5}}[/tex]

una dintre fetele laterale ale unei piramide patrulatere regulate este triunghi echilateral cu latura de 7cm. Calculati aria bazei piramidei consideratei
Answer:
21.27 cm^2
Step-by-step explanation:
Pentru a calcula aria bazei, putem folosi formula lui Heron Matematic aceasta este;
A = √s (s-a) (s-b) (s-c)
Unde s = (a + b + c) / 2
a, b, c se referă la laturile triunghiului
A = (7 + 7 + 7) / 2 = 21/2 = 10,5
A = √10,5 (10,5-7) (10,5-7) (10,5-7)
A = √10,5 (3,5) (3,5) (3,5)
A = √450.1875
A = 21.2176 cm ^ 2, care este de aproximativ
21.22 cm ^ 2

89
90
Answer:
5.6
Step-by-step explanation:
Sheryl got the following scores on her spelling tests.
95, 89, 99, 85, 82
Mean = sum of all observations/ Number of observations
Sum of all observations [tex]=95+89+99+85+82=450[/tex]
Number of observations = 5
So,
Mean [tex]=\frac{450}{5}=90[/tex]
Let M denotes the mean
Mean absolute deviation [tex]=\frac{\sum_{i=1}^{n}\left | x_i-M \right |}{n}[/tex]
Put [tex]n=5[/tex]
So,
Mean absolute deviation [tex]=\frac{\sum_{i=1}^{5}\left | x_i-M \right |}{5}=\frac{|95-90|+|89-90|+|99-90|+|85-90|+|82-90|}{5}=\frac{5+1+9+5+8}{5} =\frac{28}{5}=5.6[/tex]

Step-by-step explanation:
Paul is going to purchase orange juice and soda water for a new fruit punch recipe. The recipe calls for 3.5 times as many bottles of soda water as orange juice. If he has $20.55, what is the most bottles of orange juice he can buy if orange juice costs $3.70 per bottle and soda water costs $0.90 per bottle?
Answer:
10.5 bottles of orange juice
Step-by-step explanation:
Paul is going to purchase orange juice and soda water for a new fruit punch recipe. The recipe calls for 3.5 times as many bottles of soda water as orange juice. If he has $20.55, what is the most bottles of orange juice he can buy if orange juice costs $3.70 per bottle and soda water costs $0.90 per bottle?
Number of bottles of orange juice = x
Number of bottles of soda water = y
The recipe calls for 3.5 times as many bottles of soda water as orange juice.
Hence,
x = 3.5y
If he has $20.55, what is the most bottles of orange juice he can buy if orange juice costs $3.70 per bottle and soda water costs $0.90 per bottle
We have:
3.70y + 0.90× 3.5= 20.55
3.70y + 3.15y = 20.55
6.85 = 20.55
y = 20.55/6.85
y = 3 bottles
Since, Number of bottles of soda water = y, Number of bottles of soda water = 3
Note that: x = 3.5y
x = 3.5 × 3
x = 10.5 bottles
Number of bottles of orange juice = x, Hence, number of bottles of orange juice = 10.5 bottles

What is -4/5 divided by 2/3? I can't figure out how to get the answer and the calculators are no help at all.
If you're asking for improper, It's -6/5.
If you're asking for decimal. it's -1.2
If you're asking for mixed number, It's -1 1/5.
Answer:
-2/15
Step-by-step explanation:
Apply the fractions formula for addition, to
− 45 + 23
and solve
( −4 × 3 ) + ( 2 × 5 ) 5 × 3
= − 12 + 10/15
= −2/15
Therefore:

What is the value of 58 ? (1 point)
Answer:
1/25
Step-by-step explanation:
Answer:
Step-by-step explanation: The absolute value of 58 is the distance between 58 and 0 on a number line. See illustration below where x is 58: Since the distance between 58 and 0 on a number line is 58, we get the answer as follows: |58| = 58. Note that the absolute value of 58 can also be written as abs (58) which may be useful to know if you have a good calculator.
Alex bar and Carl are brothers Alex is the oldest and Carl is the youngest the some of the ages of the three brothers is 42 Alex his age is three more than twice Carl's age the difference between Barts in Carl's ages is seven years how old is each brother
Answer:
Alex = 19 years
Bart's = 15 years
Carl = 8 years
Step-by-step explanation:
Let us represent their ages as
Alex = x
Bart's = y
Carl = z
the sum of the ages of the three brothers is 42
x + y + z = 42
Alex his age is three more than twice Carl's age
x = 2z + 3
The difference between Barts in Carl's ages is seven years
y - z = 7
y = 7 + z
Hence: we Substitute
x + y + z = 42
2z + 3 + 7 + z + z = 42
Collect like terms
2z + z + z + 10 = 42
4z = 42 - 10
4z = 32
z = 32/4
z = 8 years
Hence, Carl = 8 years old
a) y = 7 + z
y = 7 + 8
y = 15 years.
Hence, Bart's is 15 years old
b)x = 2z + 3
x = 2(8) + 3
= 16 + 3
= 19 years
Therefore, Alex is 19 years old.
HELP, I WILL GIVE ALOT OF POINTS AND BRAINLYEST
Answer:
C
Step-by-step explanation:
first, let's find the midpoint of line TR.
((x1+x2)/2, (y1+y2)/2)
(4+8)/2= x-coordinate= 6
(-4+-4)/2=y-coordinate=-4
(6,-4) is the point of A
now, use the distance formula for U (5,-6) and A (6,-4)
d= sqrt (x2-x1)^2 + (y2-y1)^2
d= sqrt (6-5)^2 + (-4-(-6))^2
d= sqrt (1+4)
d= sqrt 5

Lance and Brandon purchased items at the sporting goods store and spent the same amount of money. Lance bought 18 shirts for his team, and Brandon bought 12 of the same shirts for his team plus a $75 pair of shoes. How much did each shirt cost?
Answer:
$12.50
Step-by-step explanation:
18 - 12 = 6
Brandon bought 6 less than Lance and payed $75 dollars shoes.
That means that 6 shirts cost $75.
We need to divide 6 from 75
75/6 = 12.5
So each shirt costs $12.50.
