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?

Answers

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.

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?

Answers

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.

What is the value of the expression (-2)^3 (3)^0 (4)^-2

Answers

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

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.

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.

The length of a rectangle is
four times its width. If the
area is 100 meters squared,
what is the length of the
rectangle?

Answers

Answer:

5 is the width 20 is the length

Step-by-step explanation:

5*4= 20 and 20*5=100

We know that the area of any rectangle is length times width. The perimeter is the sum of twice the length and twice the width.

Let width = x
Let length = 4x
Area = 100m2


Next, we can write an equation using these variables and formula for area.

4x2 = 100

x2 = 25


x = -5 and x = 5

Since the dimensions cannot be negative, we accept the positive value:

x = 5


Next, we can substitute this value of x into the variables.

width = 5 m
length = 20 m


Finally, we can find the perimeter by plugging in these dimensions into the perimeter formula,

Perimeter = 2(5 m) + 2(20 m)
= 10 m + 40 m
= 50 m

In a class 21 of students, 7 have a brother and 6 have a sister. There are 4 students who have a brother and a sister. What is the probability that a student who has a brother also has a sister?

Answers

Let x be the number of students having both brother and sister.

Brother only is 7-x
Sister only is 6-x


Brother only + sister only + both + neither = 21
(7-x) + (6-x) + x + 4= 21
-4 - x = 21
x = 17

Per definition of conditional probability:
prob( brother | sister) = prob ( brother AND sister) / prob ( sister)
17/6 = 2 5/6
17/6 = 2 5/6 = 25%

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.

Answers

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
