Answer:
x = -28
Step-by-step explanation:
−1/4x=7
Multiply each side by -4 to isolate the variable
-4 * −1/4x= -4*7
−1/4x=7
Answer:
start at 3 1/8, subtract 3/4 write the first four terms of the sequence
Step-by-step explanation:
3 1/8
2 3/8
1 5/8
7/8
are the first 4 terms.
Answer:
Step-by-step explanation:
Recall that a cosine function of the form has the following:
- amplitude A
- Frequeny .
- Phase shift
- Midline D
So, in our case, we know that A=3, (which implies that ) and D=5. Since we are not said everything about the Phase shift, lets asumme that the Phase shift is 0. Hence C=0.
Then, our desired function is
Answer:
3.73 m
Step-by-step explanation:
1375 mm Hg corresponds to a pressure of 18693.264 kgf/m^2.
Dividing that by the density will give the depth allowed, which is the diameter of the sphere:
(18693.264 kgf/m^2)/(5010 kgf/m^3) ≈ 3.73 m
The sphere can be up to 3.73 m in diameter.
_____
1 kgf is the force produced by a 1 kg mass in Earth's gravity field, about 9.8 N.
- you will need 2 busses to only transport the boys.
- Mark is at (1 + 5/6) miles of his house.
<h3>How many buses would it take to carry only the boys?</h3>
We know that there are (3 + 1/2) groups, such that each group fill one bus.
2/5 of the students are boys, then the number of groups that we can make only with boys is:
(2/5)*(3 + 1/2) = 6/5 + 1/5 = 7/5 = 5/5 + 2/5 = 1 + 2/5
Then you can make one and a little less than a half of a group, which means that you need 1 and 2/5 of a buss to transport the boys, rounding that to the a whole number, you will need 2 busses to only transport the boys.
<h3>How far is Mark from his house?</h3>
The original distance is:
D = (2 + 3/4) miles.
But Mark only covers 2/3 of that distance, then we have:
d = (2/3)*D = (2/3)*(2 + 3/4) miles = (4/3 + 2/4) miles
d = (4/3 + 1/2) miles = (8/6 + 3/6) miles = (1 + 5/6) miles
Mark is at (1 + 5/6) miles of his house.
