Answer:
S varies partly directly as M and Q.
S=C.
S=KMQ+C.
For the first one...
speed=80,m=220,Q=30.
80=K20×30+C.
80=600K+C......(I).equation one.
For the second one....
speed=60,m=300,Q=40.
60=K300×40+C.
60=12000K+C.....(ii). equation two.
Minus eqtn(I) from eqtn(ii).
80=600K+C.
- 60=12000K+C.
K=0.01754~0.018.
Substitute K=0.018 into eqtn(I).
80=600K+C
80=600×0.018+C.
80=10.8+C.
C=80-10.8=69.2.
The relation is S=0.018MQ+69.2
when speed is 100 and mass is 250 find the volume.
100=0.018×250×Q+69.2.
100=4.5Q+69.2.
4.5Q=100-69.2
4.5Q=30.8.
Q=30.8/4.5.
Q=6.8~7litres.

Answer:
x² - 1
Step-by-step explanation:
When x - 1 = 3 and x + 1 = 5 we know that x = 4 so (x - 1)(x + 1) = 4² - 1 when x = 4, 5² - 1 when x = 5 and so on. If you look carefully you will notice a pattern, the product is always x² - 1 so the answer to the blank is x² - 1.

Which type of conic section is described by the equation 4x^2 = 10 +y^2? Due in 2 HOURS, will give BRAINLIEST! A. Ellipse B. Circle C. Parabola D. Hyperbola
Answer:
c
Step-by-step explanation:
Hyperbola is the conic section described by the equation 4x² = 10 +y²
What is Parabola?A parabola is a plane curve which is mirror-symmetrical and is approximately U-shaped.
To identify the type of conic section from an equation whether it is circle, or ellipse a let suppose the equation as,
Ax²+By²+Cx+Dy+E=0
The given equation is 4x² = 10 +y²
4x²-y²=10
Divide the whole equation by 10
4x²/10 - y²/10=1
2x²/5- y²/10=1
x²/(1/2)- y²/10=1
The given equation is in the form of hyperbola.
Hence, hyperbola is the conic section described by the equation 4x² = 10 +y²

Bob is buying the soccer team ice cream after their game today. 8 players want ice cream cookies and 5 players want ice cream cones. If ice cream cones cost $1.25 each and ice cream cookies cost $1.75 each, how much will Bob spend on ice cream for the team?
Answer:
Bob will spend on ice cream for the team $20.25
Step-by-step explanation:
Hello!!!
In this problem we are expected to solve for the total amount that Bob will spend to buy
8 players ice cream cookies and
5 players ice cream cones
let us calculate as follows
Cost of ice cream cookies for 8 players = 8*1.75= $14
Cost of ice cone for 5 players = 5*1.25= $6.25
Total cost = $14+ $6.25= $20.25

∠A and ∠B are complementary angles. If the measure of ∠A is 42°, find the measure of ∠B.
Answer:
∠B = 48°Step-by-step explanation:
Since ∠A and ∠B are complementary angles their angles sum up to 90°.
In order to find ∠B add both ∠A and ∠B and equate them to 90° and solve for ∠B
That's
∠A + ∠B = 90
42 + ∠B = 90
∠B = 90 - 42
We have the final answer as
∠B = 48°Hope this helps you
Answer:
∠B = 48°
Step-by-step explanation:
A Complementary angles are total of 90°
If the measure of ∠A is 42°, find the measure of ∠B:
∠A + ∠B = 90°
42° + ∠B = 90°
∠B = 90° - 42°
∠B = 48°

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
We can simply each answer choice to find those which have no solution:
1. 6x + 1 = 3(2x - 4)
6x + 1 = 6x - 12
0 ≠ - 13, NO SOLUTION.
2. 2 - 5x = 7x - 12
14 = 12x
x = 7/6. 1 SOLUTION.
3. 4(3 - x) = 2(6 - 2x)
12 - 4x = 12 - 4x
0 = 0. INFINITE SOLUTIONS.
4. 5(x + 2) = 2(x - 4)
5x + 10 = 2x - 8
3x = -18
x = -6. 1 SOLUTION.
5. -4(x + 3) = 4(-x - 1)
-4x - 12 = -4x - 4
0 ≠ 8. NO SOLUTIONS.
Therefore, the only equations with no solutions are equations 1 and 5.

Nicole charges a flat fee of $15 for babysitting plus $7 per hour a) write about equation to find the total payout. b) Evaluate an equation to find the total payout if Nicole babysits for 5 hours.
Answer:
a) t = 7x + 15
b) Nicole is paid $50 for 5 hours.
Step-by-step explanation:
flat fee = a price that will not change = $15
$7 per hour = a price of $7 for an unknown amount of hours (x) = 7x
Let "x" = amount of hours.
Let "t" = total cost.
Set the equation:
t = 7x + 15
Nicole babysits for 5 hours. Plug in 5 for x in the equation:
t = 7x + 15
t = 7(5) + 15
t = 35 + 15
t = 50
Nicole is paid $50 for 5 hours.

Step-by-step explanation:
Produce BC in the direction of C which intersects DE at any point say P.

So, BP would be transversal.
[tex] \therefore m\angle DPB + m\angle FBP = 180\degree\\... (By\: interior \: \angle \: Postulate) \\
\therefore m\angle DPB + 125\degree = 180\degree\\
\therefore m\angle DPB = 180\degree - 125\degree \\
\huge \red {\boxed {\therefore m\angle DPB = 55\degree}} \\
m\angle DCP = 180\degree - 90\degree \\
m\angle DCP = 90\degree \\
x = 180\degree - (90\degree + 55\degree) \\
x = 180\degree - 145\degree \\
x = 35\degree [/tex]
