Singh's house the weekly consumption of milk is 6.5 liters what is their daily consumption of milk if they consume same quantity of milk every day
Answers
Answer:
Their daily consumption of milk is of 0.93 liters.
Step-by-step explanation:
Weekly consumption:
6.5 liters.
Daily consumption:
A week has 7 days.
Each day the amount consumed is the same, so the daily consumption is:
6.5/7 = 0.93
Their daily consumption of milk is of 0.93 liters.
A baseball is projected upward at 64 feet per second. It can be approximated by the equation -16t^2+64t. The baseball reaches it maximum height at the vertex. That can be gotten from x= −/2a . How long until the baseball reaches its full height? Note a quadratic equation can be written as ax^2+bx+c
Answers
Answer:
f(t) = -16t²+64t
t = number of secondsf(t) = height (in feet)The x-coordinate(t) of the vertex can be found using formula [tex]\frac{-b}{2a}[/tex], where:
a = -16b = 64Therefore the t-value of the vertex is:
[tex]\frac{-64}{2(-16)} =\frac{-64}{-32} =2[/tex]
The baseball will reach its maximum height after two seconds.

Answers
9514 1404 393
Answer:
24.1
Step-by-step explanation:
The third angle is C = 180° -55° -19° = 106°. The law of sines can be used to find the other two sides:
a/sin(A) = c/sin(C) ⇒ a = c(sin(A)/sin(C))
b/sin(B) = c/sin(C) ⇒ b = c(sin(B)/sin(C))
Then the sum of the lengths of the sides is ...
P = a + b + c = c(sin(A)/sin(C)) +c(sin(B)/sin(C)) +c
= c(1 +(sin(A) +sin(B))/sin(C)) = 11(1 +(0.8192 +0.3256)/0.9613)
≈ 11(1 +1.1909) ≈ 24.0994

Does the graph below represent a proportional relationship?
———————————————
A. Yes, because the graph is a straight line
B. No, because it crosses the y -axis
C. Yes, because it crosses the y -axis
D. No, because the line doesn't pass through the origin, point (0,0)
Answers
The reason being straight lines mean equal proportions, while curved lines are exponential or quadratic.
Answer: D. No, because the line doesn't pass through the origin, point (0,0)
Explanation:
A direct proportional graph is always a straight line through the origin.
Algebraically, the form of any direct proportion equation is y = kx, where k is some constant. It plays the role as the slope.
We can rewrite y = kx as y = kx+0 to see that the y intercept is always 0 for these types of equations.
Unfortunately, this line shown has a y intercept of 2 instead of 0. So it's not a direct proportion.

So that's why the answer is choice C
The requirement that x is nonzero isn't technically necessary. The original expression simplifies to choice C even when x = 0 is the case. Also, we don't have issues such as division by zero errors that could arise. It's a bit curious why your teacher put in that condition.
Answer:
C.
Step-by-step explanation:
7x²×sqrt(2x⁴)×6×sqrt(2x¹²)
we see right away that as constant multiplication factor we have 7×6 = 42.
and then we get from each sqrt expression a sqrt(2), which leads to sqrt²(2) = 2 and therefore 42×2=84.
the only answer option with 84 is C.
now, to be completely sure, and to get some practice, let's look at the other parts :
sqrt(2x⁴) = sqrt(2)×sqrt(x⁴) = sqrt(2)×x²
sqrt(2x¹²) = sqrt(2)×sqrt(x¹²) = sqrt(2)×x⁶
=>
7x²×sqrt(2)×x²×6×sqrt(2)×x⁶ =7×6×2×x²×x²×x⁶ = 84x¹⁰
perfect. C is confirmed.

C: (3, 1), (4, 1), (5, 1)
D: (4, 1), (8, 2), (12, 3)
E: (2, 1), (4, 3), (5, 4)
Answers
Answer:
B and D
Step-by-step explanation:
in B the ratio of x/y = 1 for all pairs.
in D the ratio of x/y = 4 for all pairs.
in all other sets there are different ratios inside the set.
Answer:
The pairs (2, 2), (4, 4), and (6, 6) have ratios of 1 and the pairs (4, 1), (4, 1), (8, 2), and (12, 3) have ratios of 4. The other pairs do not have similar ratios.
Step-by-step explanation:
Step 1; In order to pair up the pairs with equivalent rations, we first need to calculate the ratios for all the pairs by dividing the first value with the second value. The same procedure must be followed throughout to be able to pair them up.
Step 2; By dividing the values, the ratios are;
For (1, 2), the ratio is = 0.5,
For (2, 3), the ratio is = 0.6666,
For (4, 7), the ratio is = 0.5714,
For (2, 2), the ratio is = 1,
For (4, 4), the ratio is = 1,
For (6, 6), the ratio is = 1,
For (3, 1), the ratio is = 3,
For (4, 1), the ratio is = 4,
For (5, 1), the ratio is = 5,
For (4, 1), the ratio is = 4,
For (8, 2), the ratio is = 4,
For (12, 3), the ratio is = 4,
For (2, 1), the ratio is = 2,
For (4, 3), the ratio is = 1.333,
For (5, 4), the ratio is = 1.25.
Step 3; Now we pair up the sets with the same ratios, out of these 15 pairs. The pairs (2, 2), (4, 4), and (6, 6) have ratios of 1 and the pairs (4, 1), (4, 1), (8, 2), and (12, 3) have ratios of 4. The other pairs do not have similar ratios.
