Answer:
19 ; 2.8 hours
Step-by-step explanation:
Find the value of y for which the value of 8y+3 is 7 more than the value of 6y
8y + 3 = 7 + 6y
8y - 6y = 7 - 4
2y = 3
y = 3/2
y = 1.5
Let
Tom's rate = x
Sam's rate = y
Rate = 1 / time
Hence,
x = 1/7
Rate when they work together = 1/2
Tom's rate + Sam's rate = 1/2
1/7 + y = 1/2
y = 1/2 - 1/7
y = (7 - 2) / 14
y = 5/14
Since, rate = 1/time
Time = 1/ rate
Sam's time = 1/ rate = 1/y = reciprocal of y
Sam's time = 14/5 = 2.8 hours
2.8 hours = 2 hours (0.8 * 60) = 2 hours 48 minutes
A man sold two radios at Rs. 4800 each. On one he gains 20% and on the another
he loses 20% . Find the gain or loss percent in the whole transaction.
SP of first Radio = Rs. 4800
Gain% on first radio = 20%
Find:The gain or loss percent in the whole transaction.
Solution:We know that,
CP = (100/100 + gain% ) * SP
Hence,
⟹ CP of first Radio = (100/100 + 20) * 4800
⟹ CP of first Radio = 100 * 4800/120
⟹ CP of first Radio = Rs. 4000
Similarly,
SP = (100 - loss%/100) * CP
⟹ 4800 = (100 - 20/100) * CP of second Radio
⟹ 4800 * 100/80 = CP of second Radio
⟹ Rs.6000 = CP of second Radio
Now,
Total SP of radios = 4800 + 4800 = Rs. 9600
Total CP of radios = 4000 + 6000 = Rs. 10000.
We observe that,
CP > SP
So, a loss is occured.
⟹ Loss = CP - SP
⟹ Loss = 10000 - 9600
⟹ Loss = Rs. 400
Now,
Loss% = (Loss/CP) * 100
⟹ Loss% = 400/10000 * 100
⟹ Loss% = 4%
∴ The loss occurred in the whole transaction is 4 %.
I hope it will help you.
Regards.

How many different solutions does (x+1)(x-1)(x+2)(x+1) have?
Answer:
Perhaps this will help. We have 11 identical candies, that we wish to distribute between 3 children C1. C2, and C3. (Possibly one or more of the children will get no candies.) For every solution of x1+x2+x3=11, we have a way of distributing the candies, x1 to C1, x2 to C2, and X3 to C3. conversely, every distribution of candies gives us a solution to x1+x2+x3=11.

A rectangular section of wilderness will be set aside for a new wildlife refuge. It's dimensions are 5.2 × 105meters by 3.7 × 106meters. Find the area of the land in square meters.
Answer:
The area of the land in square meters is 1.924 x 10⁷ m²
Step-by-step explanation:
Given;
length of the wilderness, L = 3.7 × 10⁶ meters
width of the wilderness, W = 5.2 × 10⁵ meters
Area of the land in square meters is given by;
A = L x W
Where;
A is the area of the land
L is length of the land
W is width of the land
A = 5.2 × 10⁵ meters x 3.7 × 10⁶ meters
A = 5.2 × 10⁵ meters x 37 × 10⁵ meters
A = 192.4 × 10⁵ m²
A = 1.924 x 10⁷ m²
Therefore, the area of the land in square meters is 1.924 x 10⁷ m²
Part A
The cost of having one pizza delivered is $14. Each additional pizza costs $9 more. Choose the explicit formula to represent the situation.
A. an = 14 + 9(n + 1)
B. an = 5 + 9n
C. an = 14 + 9n
D. an = 5 + 9(n + 1)
Part B
The cost of having one pizza delivered is $14. Each additional pizza costs $9 more. Choose the recursive formula to represent the situation.
A. an = an – 1 + 5; a1 = 14
B. an = an – 1 + 23; a1 = 9
C. an = an – 1 + 14; a1 = 9
D. an = an – 1 + 9; a1 = 14
Answer: C
For part b, the answer is also C.
Step-by-step explanation:
14 Is the rate for the first pizza, then add 9 per pizza after that, so an=14+9n

What is the value of the expression (-2)^3 (3)^0 (4)^-2
Answer:
(-1)/2
Step-by-step explanation:
Simplify the following:
(-2)^3×3^0/4^2
4^2 = 16:
((-2)^3×3^0)/16
3^0 = 1:
(-2)^3/16
(-2)^3 = (-1)^3×2^3 = -2^3:
(-2^3)/16
2^3 = 2×2^2:
(-2×2^2)/16
2^2 = 4:
(-2×4)/16
2×4 = 8:
(-8)/16
The gcd of -8 and 16 is 8, so (-8)/16 = (8 (-1))/(8×2) = 8/8×(-1)/2 = (-1)/2:
Answer: (-1)/2

In the transformed quadratic functiong (X) = (x – 8)2 + 5, two
transformations occurred: horizontal translation to the right by 8 units
and
O Vertical translation up by 5 units
O Vertical Translation down by 5 units
Vertical stretch by a factory of 5
O Reflection over the X – axis
10t
Answer:
Vertical translation up by 5 unitsExplanation:
From vertex form of quadratic function g(x)=a(x-h)²+k the h and k are coordinates of vertex transformed from point (0,0) which is the vertex of parental function f(x)=ax²
It means the h determines how many units we moved parental graph horizontaly (to the left if h<0, to the right if h>0) and the k determines how many units we moved parental graph verticaly (down if h<0, up if h>0)
g(x) = (x - 8)² + 5 ⇒ h = 8, k = 5
So if h and k are >0 it means the parental graph was moved to the right and up.
Sharon has 10 ½ gallons of paint. She plans on using 1 ½ gallons to paint each room in her house. How many rooms will she be able to paint if she shares the paint equally in each room?
Answer:
3 rooms can be fully painted if the paint is shared equally.
As well as 2/3 of another room.
Step-by-step explanation:
Sharon has 10 ½ gallons of paint. She plans on using 1 ½ gallons to paint each room in her house.
Hence:
1 ½ = 1 room
10 ½ = x
Cross Multiply
x × 1 ½ = 10 ½ × 1
x = 10 ½ × 1/1 ½
x = 11/2 ÷ 3/2
x = 11/2 × 2/3
x = 11/3
x= 3 2/3 rooms
How many rooms will she be able to paint if she shares the paint equally in each room?
Hence, she will be able to paint 3 rooms fully as well as 2/3 of another room.
The speed limit on a road is 45 miles per hour. What is this rate in miles per minute?
1 hour = 60 minutes
Divide miles per hour by 60 minutes:
45/ 60 = 0.75 miles per minute
If you need the answer as a fraction 0.75 = 3/4 miles per minute.

need help with this. its very hard and i dont know what to do and my work is due at 11:59 pm today .
Answer:
125°
Step-by-step explanation:
Sum of all the internal angles in a triangle is 180°
So, we have,
67°+58°+ Adjacent angle of 1 = 180°
125°+Adjacent angle of 1 = 180°
Adjacent angle of 1 = 180° - 125° = 55°
Angle 1 and its adjacent angle are supplementary
So, Angle 1 + Adjacent angle of 1 = 180°
Angle 1 + 55° = 180°
Angle 1 = 180° - 55° = 125°

What are ratio and proportion?A ratio is a collection of ordered integers a and b represented as a/b, with b never equaling zero. A proportionate expression is one in which two items are equal.
The variable q varies inversely as the cube of v.
q ∝ 1/v³
q = k/v³
Where k is the constant of variation.
Then the equation represents this situation will be
q = k/v³
qv³ = k
Then the correct option is A.
