Answer:
[tex]\dfrac{17}{8}[/tex]
Step-by-step explanation:
Given statement:
The quotient of (8/5 divided by 8/10) is added to the product of (8/14 × 7/12 × 3/8):[tex]\implies \dfrac{\frac{8}{5}}{\frac{8}{10}}+\left(\dfrac{8}{14} \times \dfrac{7}{12} \times \dfrac{3}{8}\right)[/tex]
To divide two fractions, flip the second fraction (make the numerator the denominator, and the denominator the numerator) then multiply it by the first fraction:
[tex]\implies \left(\dfrac{8}{5} \times \dfrac{10}{8}\right)+\left(\dfrac{8}{14} \times \dfrac{7}{12} \times \dfrac{3}{8}\right)[/tex]
[tex]\textsf{Apply the fraction rule} \quad \dfrac{a}{c}\times\dfrac{b}{d}=\dfrac{ab}{cd}:[/tex]
[tex]\implies \left(\dfrac{8 \times 10}{5\times 8}\right)+\left(\dfrac{8 \times 7 \times 3}{14 \times 12 \times 8}\right)[/tex]
Carry out the multiplications:
[tex]\implies \dfrac{80}{40}+\dfrac{168}{1344}[/tex]
Simplify the fractions by dividing the numerator and denominator by the GCF:
[tex]\implies \dfrac{80 \div 40}{40\div 40}+\dfrac{168 \div 168}{1344 \div 168}[/tex]
[tex]\implies \dfrac{2}{1}+\dfrac{1}{8}[/tex]
Make the denominators of both fractions the same:
[tex]\implies \dfrac{2 \times 8}{1\times 8}+\dfrac{1}{8}[/tex]
[tex]\implies \dfrac{16}{8}+\dfrac{1}{8}[/tex]
[tex]\textsf{Apply the fraction rule} \quad \dfrac{a}{c}+\dfrac{b}{c}=\dfrac{a+b}{c}:[/tex]
[tex]\implies \dfrac{16+1}{8}[/tex]

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the number of chickens in the farm be = x
Let the number of cows in the farm be = y
Now , the total number of animal heads in the farm = 43
So , the equation will be
x + y = 43 be equation (1)
Now ,
The total number of cow legs = 124
The number of legs for cows = 4
So , the equation will be
4y = 124
Divide by 4 on both sides of the equation , we get
y = 31 be equation (2)
Now , the value of y is 31 , substitute the value of y in equation (1) , we get
x + y = 43
x + 31 = 43
Subtracting 31 on both sides of the equation , we get
x = 12
And , the value of x is 12
Therefore , the number of chickens is 12 and number of cows is 32
Hence , The number of chickens in the farm = 12 chickens
The number of cows in the farm = 32 cows

a) The area of Helen's circular garden is 314 m².
b) The estimation for the number of boxes of grass seed Helen needs, is 5 boxes.
c) B. The estimation we did in (b) is an underestimation.
How to find the area of a circle?The area of a circle is calculated by the formula,
A = πr² sq. units; r - radius
When we have the diameter, we can find the radius by
r = d/2 units
Calculation:Given that Helen has a garden in the shape of a circle of diameter 20 m.
She is going to cover the garden with grass seed to make a lawn.
Grass seed is sold in boxes. Each box of grass seed will cover 58 m² of the garden.
a) The area of the circular garden is
A = πr² = 3.14 × (d/2)²
⇒ A = 3.14 × (20/2)²
⇒ A = 3.14 × 100
∴ A = 314 m²
Thus, the area of Helen's garden is 314 m².
b) The number of boxes of grass seed to cover the area of 314 m² is
= area of the garden/area covered by each box of seeds
= 314 m²/58 m²
= 5.4179
So, on an estimation, there are 5 boxes of grass seed that Helen needs.
c) Here, in the above estimation, we rounded the decimal number 5.4179 to 5. Since the number is rounded to the nearest value (smallest value), the estimation is an underestimate.

A solid has a volume of 128 cubic units and a surface area of 160 square units. The solid is dilated, and the image has a volume of 54 cubic units.
What is the surface area of the image?
Answer:
90 units²
Step-by-step explanation:
The scale factor of the lengths of the sides of a solid must be squared to to find the ratio of the areas and cubed to find the ratio of the volumes.
For example, if you are given two solids with a scale factor of the lengths of the sides of 2, meaning that the sides of the second solid are twice the length of the sides of the first solid, then the surface area of the second solid is 2² (= 4) times the surface area of the original solid, and the volume of the second solid is 2² (= 8) times the volume of the original solid.
Let's say you have a cube with edge of 1 cm. The volume is (1 cm)³ = 1 cm³.
The surface area is the sum of the areas of the 6 faces which are squares 1 cm by 1 cm. 6 × (1 cm)² = 6 × 1 cm² = 6 cm².
The original cube with edge of 1 cm has a volume of 1 cm³ and total surface area of 6 cm².
Now double the size of the edge of the cube. The new cube has an edge of 2 cm. The volume is (2 cm)³ = 8 cm³. Each face of the cube is a square 2 cm by 2 cm. The total surface area of the new cube is 6 × (2 cm)² = 24 cm².
The new cube has volume 8 cm³ and total surface area 26 cm².
Compare the edges, surface areas and volumes of the two cubes:
Original Cube Dilated Cube Ratio new/dilated
Edge 1 cm 2 cm 1:2
Surface area 6 cm² 24 cm² 1:4
Volume 1 cm³ 8 cm³ 1:8
Now here is your problem.
We start with the ratio of the volumes.
Original solid: 128 u³
Dilated solid: 54 u³
ratio of volumes: 54/128 = 27/64 = 3³/4³
The ratio of volumes is the cube of the ratio of the lengths.
ratio of lengths: 3/4
ratio of area: 3²/4² = 9/16
Surface area of original solid: 160 u² × 9/16 = 90 u²
Answer: 90 units²

The width of a rectangle is the length minus 6 units. The area of the rectangle is 7 units. What is the length, in units, of the rectangle?.
The length of the given rectangle is 7 units.
What is the area of the rectangle?The area of the rectangle is the product of its length and width.
I.e., A = l × w sq. units
Calculation:It is given that, the width of a rectangle is the length minus 6 units.
I.e., W = L - 6 units
Then, the area of the rectangle is
A = L × (L - 6)
But we have given that, the area of the rectangle is 7 sq. units.
So, we can write
7 = L² - 6L
⇒ L² - 6L - 7 = 0
⇒ L² - 7L + L - 7 = 0
⇒ L(L - 7) + 1(L - 7) = 0
⇒ (L + 1)(L - 7) = 0
∴ L = -1 or L = 7
The length should not be a negative value. So, the length of the given rectangle is 7 units.
Then, the width of the rectangle is
W = L - 6 = 7 - 6 = 1 unit.
