3x10=30

Answer:

$2.10

Step-by-step explanation:

first we want to find for one kg. one kg is $0.30.

Multiply that by 7 and you get $2.10

Answer:

$23.10

Step-by-step explanation:

8.25 ÷ 2.5 = 3.3

7 x 3.3 = 23.10

you have to find out how much money you pay per kg

you pay $3.30 per kg

therefore you have to multiply the kg (7) by the price (3.30) and that's why you get $23.10

A function assigns values. The rectangular equation can be described as cubic.

A function assigns the value of each element of one set to the other specific element of another set.

As the function of x and y is given, therefore, if we eliminate t from both the function we will get,

[tex]x=t^{\frac12}\\\\x=\sqrt t\\\\x^2=t[/tex]

Now, substitute the value of t in the function of y,

[tex]y= t-4\\y=x^2-4[/tex]

Further, the rectangular equation can be written as,

[tex]\text{Rectangular Equation} = x \times y[/tex]

                                   [tex]= x \times (x^2-4)\\\\= x^3-4x[/tex]

Thus, the rectangular equation can be described as cubic.

Step-by-step explanation:

180-43 (these two angles plug into all the angles)

Answer:

Step-by-step explanation:

→ Given angles of triangle = 45° + 45° + 90° {from <3>}

→ x = y {because of <1>}

→ H² = P² + B² (Pythagoras Theorem) {from <2>}

→ (12)² = x² + y²

→ 144 = x² + x² [x = y]

→ 144 = 2x²

→ 144/2 = x²

→ 72 = x²

→ √(72) = x

→ 6√2 = x

→ x = y

so,

x = 6√2 = y

The correlation Coefficient, R shows the degree or level of relationship between the dependent and independent variable. A positive R value denotes a positive correlation while a negative R value denotes a negative relationship. R values should range between - 1 to +1 with values close to 1 and - 1 depicting strength while value of zero means no relationship exist.

Hence, R value of -0.90 depicts a strong negative relationship. Hence, higher speed are related to lower miles per gallon and vice versa.

Reading through the problem, we have "15 is",

that's "15 =", 15%, 15/100, "of", times, "what number", x.

So our equation reads 15 = 15/100 · x.

Answer:

33/130

Step-by-step explanation:

3/4 - 1/5 = 11/20

5/2 - 1/3 = 2 and 1/6

11/20 divided by 13/6 = 33/130

Answer:

Step-by-step explanation:

a₁ = -3 = (-1)¹×3

a₂ = 6 = (-1)²×2×3

a₃ = -28 = (-1)³×2²×7

a₄ = 72 = (-1)⁴×2³×3²

a₅ = -360 = (-1)⁵×2³×3²×5

a₆ = 2160 = (-1)⁶×2⁴×3³×5

That's as far as I got. I can predict that a₇ is a multiple of -32 and a₈ is a multiple of 64, but I don't see the pattern with the other factors.

Answer:

1. 1/8 ÷ 3/4 = 1/6

2. 3/5 ÷ 3/2 = 2/5

3. 4/1 ÷ 2/3 = 6

4.9/4 ÷ 6/5 = 15/8

Answer: See explanation

Step-by-step explanation:

Ally served 40% of the customers

Benny served 27%

Percentage served by Charli will be:

= 100% - (40% + 27%)

= 100% - 67%

= 33%

That night 60% of Ally's customers ordered pie, while 40% did not. Of Benny's customers, 20% ordered pie.

The percent that did not will be:

= 100% - 20%

= 80%
