Jamie has 70 coins. They total $6.30. If they are only dimes and nickels find out how many of each she has.​

Answers

Answer 1

Answer:

Jamie has 14 nickels and 56 dimes

Step-by-step explanation:

Start by identifying labels for the # of dimes and nickles. Lets use x for nickels and y for dimes.

From here you can make two formulas (x + y = 70) and (5x + 10y = 630) when you put them into a graphing calculator they should intersect at (14,56) which means the x = 14 and y = 56

Choose 1 answer:

Answers

7(a)
1/a x 7 would give you your equivalent expression

The equivalent expression to given expression 1/a⁷ is a⁻⁷. So, correct option is A.

The equivalent expression to 1/a⁷ can be found using the rule of exponents.

The rule states that when a non-zero number is raised to a negative exponent, it becomes the reciprocal of the number raised to the positive exponent.

In this case, the expression 1/a⁷ has a negative exponent, which means it can be written as the reciprocal of a raised to the positive exponent:

1/a⁷ = a⁻⁷

So, the correct equivalent expression is option a) a⁻⁷.

Option b) 7ᵃ is not equivalent to 1/a⁷. 7ᵃ means "7 raised to the power of a," which is different from 1/a⁷.

Option c) None of the above is also not correct because option a) a⁻⁷ is indeed the equivalent expression to 1/a⁷.

In summary, the equivalent expression to 1/a⁷ is a⁻⁷, which is option a).

the points (0 1) and (1 4) are contained in the graph of an equation with only two variables x and y

Answers

The line that passes through (0 1) and (1 4) is a linear equation

The equation of the points is y = 3x + 1

How to determine the equation of the points?

The points are given as:

(x,y) = (0 1) and (1 4)

Start by calculating the slope (m)

m = (y₂ - y₁)/(x₂ - x₁)

So, we have:

m = (4 - 1)/(1 - 0)

Evaluate

m = 3

The equation is then calculated as:

y = m(x - x₁) + y₁

This gives

y = 3(x - 0) + 1

Evaluate the product

y = 3x + 1

Hence, the equation of the points is y = 3x + 1

∠S = 58°

Step-by-step explanation:

RA = AD

∠BAD = ∠SRA

∠BAD + ∠RAB = straight line, 180° (supplementary angles)

Solve for x

∠BAD + ∠RAB = 180°

(6x + 8) + (9x + 7) = 180°

15x + 15 = 180

15x = 165

x = 11

Find ∠S

∠S = 4x + 14

∠S = 4(11) + 14

∠S = 44 + 14

The figure shows parallelogram PQRS on a coordinate plane. Diagonals SQ and PR intersect at point T. P(2b, 2c) Q(?, ?) T S(0, 0) R(2a, 0) Part A Find the coordinates of point Q in terms of a, b, and c. ​

Answers

The coordinates of point Q is the location of point Q in the parallelogram

The coordinates of point Q is (2b + 2a,2c)

How to determine the coordinates of Q?

The coordinates are given as:

P(2b, 2c) Q(?, ?)  S(0, 0) R(2a, 0)

Since the shape is a parallelogram; it means that the distance PQ is the same as the distance RS.

The distance RS is calculated as:

RS = (2a - 0, 0 - 0)

This gives

RS = (2a, 0)

The coordinates of  Q is then calculated using:

Q = P + RS

This gives

Q = (2b,2c) + (2a,0)

Evaluate the sum

Q = (2b + 2a,2c)

Hence, the coordinates of point Q is (2b + 2a,2c)

the length of a rectangle is x+6 The width of a rectangle is 3x+4 find the perimeter

Answers

Answer:

8x + 20 or 4(2x + 5)

Step-by-step explanation:

Perimeter equals length + width times 2. If the width is 3x + 4, and the length is x+6, you first add 3x + 4 + x + 6. You first add the like terms, 3x and x, which is 4x. Now you add 4 and 6, which equals ten. Now, you get 4x + 10. Lastly, you have to multiply it by two. 4x + 10 + 4x + 10 equals to 8x + 20. You add up the like terms 4x and 4x and 10 and 10, to get the total of 8x + 20.

Write the function that is modeled in the graph below:

Answers

The sinusoidal function that is modeled in the graph presented in this question is the expression y = 5 + 3 · sin [π · (x+2)/4], where x and y are the independent and dependent variable, respectively.

How to model a sinusoidal function

In this question we must analyze periodic functions to determine the most appropriate model that best fit with the graph, the determination of the model will determine the inherent characteristics of the model. The graph seem to be a sinusoidal function.

Sinusoidal functions are bounded functions characterized by use of trigonometric expressions and the presence a lower and a upper bound, a period and phase. The entire formula is described below:

y = r + 0.5*(M-m) · sin [2π · (x-F)/T]     (1)

Where:

r - Middle valuem - Lower boundM - Upper boundF - Phasex - Independent valuey - Dependent valueT - Period

The period is the time in which a sinusoidal function completes a cycle and the phase is a horizontal translation applied to a canonical sinusoidal function.

If we know that r = 5, m = 2, M = 8, T = 8 and F = -2, then the sinusoidal function is:

y = 5 + 3 · sin [π · (x+2)/4]

The sinusoidal function that is modeled in the graph presented in this question is the expression y = 5 + 3 · sin [π · (x+2)/4], where x and y are the independent and dependent variable, respectively. [tex]\blacksquare[/tex]
