Answer:

2.5cm³

Step-by-step explanation:

The formula for volume is base/ height.

So first to find to base you would multiply 1 cm times 1cm. Which would give you 1cm²

Then you would multiply that by the 2.5 cm height, which would give you the volume of 2.5 cm³.

Answer:

T = 6.41 hours

Step-by-step explanation:

Fishing for Friday =  3 7/12 hours

Fishing for Saturday  =2 5/6 hours

We need to find for how long Diana went fishing on Friday and Saturday combined. It means we need to add the time for Friday and Saturday. So,

[tex]T=3\dfrac{7}{12}+2\dfrac{5}{6}\\\\=\dfrac{3(12)+7}{12}+\dfrac{2(6)+5}{6}\\\\=\dfrac{43}{12}+\dfrac{17}{6}\\\\=6.41\ \text{hours}[/tex]

So, the combined timing is 6.41 hours.

The time taken for her to reach the amount of $106,200 will be 17 years.

Compound interest is the interest levied on the interest. The formula for the calculation of compound interest is given as:-

Given that:-

The formula for calculating the compound interest continuously.

[tex]A \ = \ P e^ {rt}[/tex]

[tex]106200\ = \ 54000e^{0.04t}\\\\\\\dfrac{106200}{54000}=e^{0.04t}\\\\\\1.97\ = \ e^{0.04t}\\\\\\Ln(1.97)=Ln(e^{0.04t})[/tex]

Ln(1.97) = 0.04t

t  =   17 years.

Therefore the time taken for her to reach the amount of $106,200 will be 17 years.

Answer:

$0.22

Step-by-step explanation:

Ellen has a coupon of 1.55 off a loaf of bread

The regular price of the bread is 4.63, the loaf is cut into 14 slices

Therefore if she uses her coupon the price per slice can be calculated as follows

= 4.63-1.55

= 3.08

3.08/14

= 0.22

Hence the price is $0.22

Answer:

3.6h - 3.1d + 13

Step-by-step explanation:

Combine like terms. Like terms have same variables.

Like terms : (i) 6h and (-2.4h) (ii) -8.1d and 5d

6h + (-8.1d) - 13  + 5d - 2.4h = 6h - 2.4h + (-8.1d) + 5d - 13

             = (6 - 2.4)h + (-8.1 + 5)d - 13

             = 3.6h - 3.1d + 13

Answer:

424 cm²

Step-by-step explanation:

The figure is composed of a square and a trapezium on top

A of square = 18² = 324 cm²

A of trapezium = [tex]\frac{1}{2}[/tex] h (b₁ + b₂ )

where h is the perpendicular height and b₁, b₂ the parallel bases

Here h = 8, b₁ = 18 and b₂ = 7 , then

A = 0.5 × 8 × (18 + 7) = 4 × 25 = 100 cm²

Area of hexagonal park = 324 + 100 = 424 cm²

Answer:

7.2

Step-by-step explanation:

Use the distance formula:

d = [tex]\sqrt{(x2-x1)^2+(y2-y1)^2}[/tex]

Points of the diagonal: (-2, -2) and (2, 4)

d = [tex]\sqrt{(2-(-2))^2+(4-(-2))^2}[/tex]

d = [tex]\sqrt{(2+2)^2+(4+2)^2}[/tex]

d = [tex]\sqrt{(4)^2+(6)^2}[/tex]

d = [tex]\sqrt{16 + 36}[/tex]

d = [tex]\sqrt{52}[/tex]

d ≈ 7.2

Answer:

7 ( b + 4 ) = 9

Step-by-step explanation:

Let the number be = b

It is given that the :

The number is added to 4.

And the value is equal to 9 when it is 7 times the sum of the number, b and 4.

Thus according to the question, the sentence can be translated in equation form as :

7 ( b + 4 ) = 9

Thus in other word, we can say that the addition of (b + 4) when it is multiplied for 7 times, we get the result as 9.

Answer:

B

Step-by-step explanation:

[tex]x^{0} = 1\\\\\frac{x^{m}}{x^{n}}= \frac{1}{x^(n-m)}}, n >m\\\\\\\frac{6ab}{(a^{0}b^{2})^{4}}=\frac{6ab}{(1*b^{2})^{4}}\\\\=\frac{6ab}{b^{2*4}}\\\\=\frac{6ab}{b^{8}}\\\\=\frac{6a}{b^{8-1}}\\\\=\frac{6a}{b^{7}}[/tex]

The equivalent expression of 6ab/(a^0b^2)^4 is 6a/b^7

The expression is given as:

6ab/(a^0b^2)^4

Evaluate the exponent of 0

6ab/(b^2)^4

Apply the law of indices, and open the bracket

6ab/b^8

Apply the law of indices

6a/b^(8-1)

Evaluate the difference

6a/b^7

Hence, the equivalent expression of 6ab/(a^0b^2)^4 is 6a/b^7

25% of the length is 7.5 (seven and five tenths) feet

Step-by-step explanation:

25% of 30

7.25 feet is 25% of length.

To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.

Given:

The length of wall is 30 feet.

So, 25% of length

= 30 x 25/100

= 30 x 1/4

= 30/4

= 7. 25 feet

Hence, 7.25 feet is 25% of length.
