Answer: BRAINLIEST PLEASE
her supply has 18 pounds
Explanation:
Assume that the number of pounds in her supply is x.
We are given that:
She uses 1/3 x in salted mix and 2/9 x in unsalted mix.
This means that:
Total amount used = 1/3 x + 2/9 x = 5/9 x of her supply
Now, we are also given that:
She used 10 pounds of her supply.
This means that:
5/9 x = 10
5x = 9*10 = 90
x = 18 pounds
Hope this helps :)
The number of pounds of seeds in her supply is 18
Given:
let
her total supply = x
Supply of salted snack = 1/3x
Supply of unsalted snack = 2/9x
Total pounds of sunflower seed = 10
Total supply of sunflower seeds = salted snack + unsalted snack
10 = 1/3x + 2/9x
10 = (3x + 2x) / 9
10 = 5/9x
divide both sides by 5/9
x = 10 ÷ 5/9
x = 10 × 9/5
= (10 × 9) / 5
= 90/5
= 18
x = 18
Therefore, number of pounds of seeds in her supply is 18

Your dad is designing a new garden for your backyard. He has 26 feet of fencing to go around the garden. He wants the length of the garden to be 3 1/2 feet longer than the width. How wide should he make the garden?
Answer:
4.75 feet
Step-by-step explanation:
Perimeter for any rectangular shape is given by 2(length + width).
Fencing the garden means one wiring the garden along the perimeter.
Thus, it can be concluded that garden has perimeter of 26 feet as given in question.
__________________________________________
Let the width be x feet
given that, He wants the length of the garden to be 3 1/2 feet longer than the width
thus, length of garden = x + 3 1/2 feet = x + 3.5 feet
if length is x+3.5 feet and width is x feet.
Then perimeter = 2( x+3.5 + x) = 2(2x+3.5) = (4x + 7) feet.
This perimeter will be equal to 26 feet fence
thus,
(4x + 7) = 26
=> 4x = 26 - 7 = 19
=> x = 19/4 = 4.75 feet
x is width of garden.
Thus, he should make the garden 4.75 feet wide.

4.75

Answer:
-6/5 (This is Answer c)
Step-by-step explanation:
Re-writing this equation in standard form, we get:
25x^2 + 60x + 36 = 0. The coefficients are a = 25, b = 60 and c = 36.
The discriminant, b^2 - 4ac, is 60^2 - 4(25)(36), or 3600 - 3600, or 0.
Because the discriminant is 0, we have two real, equal roots, corresponding to
-b -60
x = ------ = ---------- = -6/5 (This is Answer c)

Find the area of the rhombus. Each indicated distance is half the length of its respective diagonal.
Answer:
24 square feet
Step-by-step explanation: There are four "triangles" of the rhombus. If you find the area of each triangle by multiplying the height by the width and divide by two, you get 6. You then multiply that by 4 to get 24.

Which expression is equivalent to (5 Superscript negative 2 Baseline) (5 Superscript negative 1 Baseline)? { answer is C }
Answer:
[tex]\frac{1}{125}[/tex]
Step-by-step explanation:
The given expression is
[tex](5^{-2}) (5^{-1})[/tex]
The expression is about two powers with the same base, so we can use the power property of multiplication, which states that we must proceed we writing only one base and sum exponents
[tex](5^{-2}) (5^{-1})=5^{-2-1}=5^{-3}[/tex]
Then, we use the negative exponent property
[tex]5^{-3}=\frac{1}{5^{3} }[/tex]
Finally, we solve the power
[tex]\frac{1}{5^{3} }=\frac{1}{125}[/tex]
Therefore, the given expression is equivalen to [tex]\frac{1}{125}[/tex].

Answer:
77 units^2
Step-by-step explanation:
I'm going to call the red square A, green square B, blue square C.
A side of a square is the square root of the area.
The Pythagorean Theorem is A^2 + B^2 =C^2.
So in other words,
33 + 44 = the side of square C^2.
33+44=77
One side of square C is √77.
Square this to get the area.
Square C's area is 77 units^2.

Answer:
y = 3x
Step-by-step explanation:
The difference between consecutive values of y are constant, that is

This constant is the required multiplier, that is
y = 3x
Which expression can be used to find 17% of 58?
A. 58 = 0.17 B. 58 = 17
C. 58 x 0.17
D. 58 x 17
Answer:
58 times 0.17 which agrees with answer C in the given list of possible answers.
Step-by-step explanation:
Notice that 17% in math terms is 17/100 = 0.17
Now to find the 17% of the number 58, we need to multiply 58 by 17/100, which gives:
58 times 0.17

Answer:
V = 687.28 cm ^3
Step by step explanation:
687.28 m ^3 is found in 3 steps.
Volume of a sphere = V=4/3πr3 = 268.8 m^3
Volume of a semi sphere = V = (2/3)πr. but i divide the top one by 2
= 268.8/2 = 134.4 m^3
Volume of a Cylinder prism = V=πr2h = 502.61 m^3
Volume of a cone V=(πr2 )h/3 = 50.27
We add 134.4 + 502.61 +50.27 = 687.28 m ^3
How to find Area;
We remember and compare to Area and other areas the values.
Area = 415m^2
circle is semi sphere A = π r2 h= 200.1 = /2 or *0.5 A=100.53 m^2
cylinder lateral A = 2πrh L = 251.327412 m^2 = 251 m^2
Cone lateral A=πrh2+r2 = 62.83 = 63 m^2
= 100.53 + 251.327412 + 62.83 =414.687412
or 101+251+63 = 415 m^2
Notes;
The best way is to find someway of not overwhelming yourself with the combined volume question and know what actually makes a cylinder being the central prism.
So write down all these values below onto a flashcard and title it Area of a composite Semi-sphere/cylinder/cone r = 4 / h= 10 r =4 / r= 4 h=3
and write these down.
Cylinder
lateral surface area L = 80 π m2
top surface area T = 16 π m2
base surface area B = 16 π m2
total surface area A = 112 π m2
Cone = 62.83
Semi sphere = 100.53
Area = 415 m2
A salesman made a trip of 420 miles by bus and train. He traveled 3 hours by bus and 5 hours by train. If the train averaged 12 mph more than the bus, find the rate of each.
Answer:
The speed at which the buss made the trip was 45 mph and the train was 57 mph.
Step-by-step explanation:
The average speed is given by:
speed = distance / time
Therefore we can manipulate it to give us the distance:
distance = speed*time
The time distance of each stage of his trip summed must be equal to the total distance of the trip. Since he made a trip in two legs, one by bus that lasted 3 h at a speed of "x" and one that lasted 5 hours at a speed of "x + 12". We have:
420 = 3*x + 5*(x + 12)
3*x + 5*(x + 12) = 420
3*x + 5*x + 60 = 420
8*x = 420 - 60
8*x = 360
x = 45 mph
The speed at which the buss made the trip was 45 mph and the train was 57 mph.
Answer:
45 mph
