A car travels at a speed of 55 kilometers per hour.Find the distance travelled by the car in 12 minutes and 30 seconds.Find the Answers in meters
Answer:
Step-by-step explanation:
(distance) d = (speed) s * t (time)
= 55km/h * 12.30m/s
= 11.275 km
= 11.275 * 1000
= 11275m
Which set of ordered pairs does not represent a function?
Answer: b
Step-by-step explanation: in order to be a function an input value should only have one output value. 8 has two output values ( 2 and -1 ) so it’s not a function.

This is circle theorems I am not rly good at this
Answer:
m∠BCD = 24°
Step-by-step explanation:
By the theorem,
"Angle subtended by an arc at the center of the circle is twice in measure of the angle subtended at the circumference."
m(∠BOD) = 2(m∠BFD)
= 2(78°)
= 156°
Therefore, m(arc BD) = m∠BOD = 156°
Since, m(arc BD) + m(arc BFD) = 360°
156° + m(arc BFD) = 360°
m(arc BFD) = 360 - 156
= 204°
Since, "angle formed outside the circle by the intersection of two tangents measure half of the difference of the intercepted arcs".
m∠BCD = [tex]\frac{1}{2}[m(\text{arc BFD})-m(\text{arc BD})][/tex]
= [tex]\frac{1}{2}[204 - 156][/tex]
= 24°

Question 1
Solve 6x≥−42. Graph the solution.
Answer:
x ≥ -7
Step-by-step explanation:
Divide both sides by 6
Then to graph it, you can make a number line
Answer:
Step-by-step explanation:
Solve 6x ≥ − 42for x by dividing both sides by 6. We get:
x ≥ − 7
Now draw a vertical line (solid) through x = -7.
Finally, shade the area including and to the right of x = -7.

Kathy owns her own business selling homemade jam. Each jar of jam weighs 18 ounces. The box she mails the jam in weighs 6 ounces. How many jars of jam are in a package that weighs 150 ounces? Show all work necessary to justify your answer.
Answer: There are 8 jars in the package.
Step-by-step explanation:
Given: Weight of each jar = 18 ounces
Weight of box = 6 ounces
If weight of package = 150 ounces , then the weight of all jars (only) = 150-6 ounces = 144 ounces
Number of jars = (Weight of all jars) ÷ (Weight of each jar)
= (144 ÷ 18)
= 8
Hence, there are 8 jars in the package.

Answer:
The x-coordinate of the intersection point (x, y) = (-0.5, -1) of the system is: -0.5
Hence, option A) i.e. -0.5 is correct.
Step-by-step explanation:
Given the system of equations
2.4x - 1.5y = 0.3
1.6x + 0.5y = -1.3
solving the system of equations
[tex]\begin{bmatrix}2.4x-1.5y=0.3\\ 1.6x+0.5y=-1.3\end{bmatrix}[/tex]
Multiply 2.4x - 1.5y = 0.3 by 2
Multiply 1.6x + 0.5y = -1.3 by 3
so the system of equations becomes
[tex]\begin{bmatrix}4.8x-3y=0.6\\ 4.8x+1.5y=-3.9\end{bmatrix}[/tex]
so
[tex]4.8x+1.5y=-3.9[/tex]
[tex]-[/tex]
[tex]\underline{4.8x-3y=0.6}[/tex]
[tex]4.5y=-4.5[/tex]
so the system of equations becomes
[tex]\begin{bmatrix}4.8x-3y=0.6\\ 4.5y=-4.5\end{bmatrix}[/tex]
solve 4.5y = -4.5 for y
[tex]4.5y=-4.5[/tex]
Multiply both sides by 10
[tex]4.5y\cdot \:10=-4.5\cdot \:10[/tex]
Refine
[tex]45y=-45[/tex]
Divide both sides by 45
[tex]\frac{45y}{45}=\frac{-45}{45}[/tex]
Simplify
[tex]y=-1[/tex]
For 4.8x - 3y = 0.6, plug in y = -1
[tex]4.8x-3\left(-1\right)=0.6[/tex]
[tex]4.8x+3\cdot \:1=0.6[/tex]
[tex]4.8x+3=0.6[/tex]
Multiply both sides by 10
[tex]4.8x\cdot \:10+3\cdot \:10=0.6\cdot \:10[/tex]
Refine
[tex]48x+30=6[/tex]
Subtract 30 from both sides
[tex]48x+30-30=6-30[/tex]
Simplify
[tex]48x=-24[/tex]
Divide both sides by 48
[tex]\frac{48x}{48}=\frac{-24}{48}[/tex]
simplify
[tex]x=-\frac{1}{2}[/tex]
or
[tex]x = -0.5[/tex]
Thus,
(x, y) = (-0.5, -1)
Therefore, the x-coordinate of the intersection point (x, y) = (-0.5, -1) of the system is: -0.5
Hence, option A) i.e. -0.5 is correct.
The radius of a right circular cylinder is increasing at the rate of 7 in./s, while the height is decreasing at the rate of 3 in./s. At what rate is the volume of the cylinder changing when the radius is 17 in. And the height is 5 in.?
Answer:
1014.73 in³/s
Step-by-step explanation:
We know the volume of a cylinder, V = πr²h where r = radius of cylinder and h = height of cylinder.
Now, to find the rate of change of volume, we differentiate it with respect to time. So
dV/dt = d(πr²h)/dt
= πhdr²/dr × dr/dt + πr²dh/dh × dh/dt
= 2πrh × dr/dt + πr² × dh/dt
when r = 17 in, dr/dt = rate of change of radius = + 7 in/s, h = 5 in and dh/dt = rate of change of height = - 3in/s (negative since it is decreasing).
So, dV/dt = 2πrh × dr/dt + πr² × dh/dt
= 2π × 17 in × 5 in × (+ 7 in/s) + π(17 in)² × (- 3 in/s)
= 1190π - 867π
= 323π in³/s
= 1014.73 in³/s

The cost before tax for an order of CDs from Music & More store was $214.60. If the store ordered 20 equally priced CDs, and the total shipping and handling fee was $15.00, what was the cost of one CD?
Answer:
Cost of one CD = $9.98
Step-by-step explanation:
Total cost = $214.60
Total shipping and handling fee = $15.00
Number of CDs = 20
Cost of 20 CDs = Total cost - Total shipping and handling fee
= $214.60 - $15.00
= $199.60
Cost of one CD = $199.60 / 20
= $9.98
Cost of one CD = $9.98
Answer:
$9.98

The edges of a cube are 5 centimeters each and the diagonal of a face is approximately 7 centimeters. What is the approximate area of the cross section passing through the diagonals of opposite faces of this cube? A. 12 square centimeters B. 25 square centimeters C. 35 square centimeters D. 49 square centimeters
Answer:
C. 35 square centimeters
Step-by-step explanation:
What we need for this question:
The edges of a cube are 5 centimeters each.
The face diagonal is about 7 centimeters. (actually 7.0710678118655 cm)
To find the cross sectional area here, multiply 5 cm by 7 cm.
5 cm * 7 cm
35 cm² is your final answer, so C is the answer.
Answer:
It is C. 35 square centimeters
Step-by-step explanation:

Step-by-step explanation:
Amy wants to buy a new set of paints. At store A, the cost is $22.00, and she has a coupon for 20% off. At store B, the cost is $22.50, and she has a coupon for $5 off. Which store has the better buy, and why?
Answer:
Store B
Step-by-step explanation:
Store A
20% is just 1/5 in percent form
22.00= 22*1/5 = 22/5 = 4.40
22.00-4.40=17.6
Store B
22.50-5=17.5
Now you can see that 17.5 is less than 17.6 by 0.1
