Answer:
r=1
Step-by-step explanation:
6-1+6r=11
add 6 and -1
5+6r=11
subtract 5 for both sides
6r=6
dived 6 from both sides
r=1

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
A gardener planted flowers of different colors.
3/10 of the flowers are yellow.
3/4 of the remaining flowers are green.
The rest are purple.
The gardener planted 119 purple flowers, how many flowers did the gardener plant?
Answer:
The gardener planted 680 flowers
Step-by-step explanation:
The different colors of flowers planted by the gardener are;
The proportion of the flowers planted that are yellow = 3/10
The proportion of the remaining flowers planted that are green = 3/4
The color of the rest of the flower planted = Purple
The number of purple flowers planted = 119 purple flowers
Let the number of flowers the gardener planted = x
Therefore, the number of yellow flowers planted = 3/10 × x
The number of green flowers planted = 3/4 × (x - 3/10 × x) = 21/40×x
The number of the rest of the flower which are purple = x - (3/10 × x+ 21/40×x) = x - 33/40×x = 7/40×x
∴ The number of the purple flowers planted = 7/40×x = 119
x = 119 × 40/7 = 680
The number of flowers the gardener planted = x = 680 flowers
The gardener planted 680 flowers.

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.

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.
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
If 2 pretzel makers can make 444 pretzels in 6 hours, how long does it take 5 pretzel makers to make 88 pretzels? Plz help me What is the answer to this equation?
Answer: Tt will take approximately 19.03 minutes.
Step-by-step explanation:
Formula required: [tex]\dfrac{M_1T_1}{W_1}=\dfrac{M_2T_2}{W_2}[/tex], where [tex]M_1[/tex] = number of men, [tex]T_1[/tex] = time taken,[tex]W_1[/tex] = work in situation 1, and [tex]M_2[/tex] = number of men, [tex]T_2[/tex] = time taken, [tex]W_2[/tex] = work in situation 2.
Given: If 2 pretzel makers can make 444 pretzels in 6 hours.
i.e. [tex]M_1=2,\ W_1=444, T_1=6\ hours[/tex]
To find : [tex]T_2[/tex] for [tex]M_25, W_2=88[/tex]
Substitute all value sin formula , we get
[tex]\dfrac{2\times6}{444}=\dfrac{5\times T_2}{88}\\\\\Rightarrow T_2=\dfrac{8\times88}{444\times5}=0.3171\ hour[/tex]
[tex]=0.3171\times 60= 19.026\text{ minutes}\ \ \ \ [\text{1 hour = 60minutes}][/tex]
hence, it will take approximately 19.03 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.
