Emily went to Kroger to buy some fruit. She needs a dozen apples and some bananas. A dozen organic apples costs $11.45 and each organic banana costs 1.05 a piece. Emily went to Trader Joe's to compare prices. At Trader Joe's a dozen apples costs $13.45 and each organic banana 97 cents a piece. Write an equation for how many bananas Emily would have to buy for Kroger and Trader Joe's to be the same cost. Use 'b' as the variable. Use the format of Kroger=Trader Joe's

Answers

Answer:

1.05(b) = 0.97(b)

Step-by-step explanation:

What you know from the problem:

Krogers:

11.45(12)+1.05(b)

Trader Joe's:

13.45(12)+0.97(b)

Kroger = Trader Joe's

1.05(b) = 0.97(b)

The equation of the parabola that represents the given graph is y = 3x².

The correct option is B.

What is a parabola?

A plane curve produced by a moving point such that its separation from a fixed point equals that of a fixed line is a parabola.

If the vertex of the parabola is at (0, 0), then the equation of the parabola has the form:

y = a x²

where "a" is a constant that determines the shape of the parabola. We need to find the value of "a" using the fact that the parabola passes through the point (1, 3).

Plugging in the coordinates of the passing point (1, 3), we get:

3 = a (1)²

3 = a

Therefore, the value of "a" is 5.

Hence, the equation of the parabola is:

y = 3x²

The function below shows the cost of a hamburger with different numbers of toppings (t). f(t) = 1.90 + 1.40t What is the y-intercept, and what does it mean?

Answers

Answer:

[tex]1.9[/tex]

the cost of the hamburger will be [tex]\$1.9[/tex] if no toppings are added.

Step-by-step explanation:

The function is

[tex]f(t)=1.9+1.4t[/tex]

Let cost of toppings be [tex]y[/tex]

[tex]y=1.9+1.4t[/tex]

The y-intercept of a function is the value of the function when [tex]x=0[/tex]. Here number of toppings [tex]t=0[/tex].

So, the intercept of the function is [tex]1.9[/tex]

This means the cost of the hamburger will be [tex]\$1.9[/tex] if no toppings are added.

How can an area model help you set

Answers

Answer: In mathematics, an area model is a rectangular diagram or model used for multiplication and division problems, in which the  or the  and  define the length and width of the rectangle.

We can break one large  of the rectangle into several smaller boxes, using number bonds, to make the calculation easier. Then we add to get the area of the whole, which is the  or quotient.

Step-by-step explanation:

For example, you can find the product 23 × 37 by finding the area of a rectangle with a width of 23 and a length of 37: Of course, there is little gained if you simply multiply 23 × 37! What makes the area model useful is that area is a conserved quantity.

solve for x -1/2x + 1/3 > 3/5​

Answers

Answer:

x > 8/15

Step-by-step explanation:

x -1/2x + 1/3 > 3/5​

Combine like terms

2/2x - 1/2x +1/3 > 3/5

1/2x   + 1/3 > 3/5

Subtract 1/3 from each side

1/2x + 1/3 -1/3 > 3/5 -1/3

1/2x  > 3/5 -1/3

Get a common denominator

1/2x > 9/15 - 5/15

1/2x > 4/15

Multiply each side by 2

2 * 1/2x > 4/15 * 2

x > 8/15

In ΔQRS, the measure of ∠S=90°, QS = 11, SR = 60, and RQ = 61. What is the value of the sine of ∠Q to the nearest hundredth?

Answers

Answer:

0.98

Step-by-step explanation:

Below is a drawing of the triangle (drawing it out is an important step if you have trouble visualizing it).

Sine = opposite/hypotenuse, in this case, SR (60) is the opposite of angle Q and RQ (61) is the hypotenuse.

Sin(angle Q) = 60/61 = 0.98

Answers

The one-sided limits around the discontinuity shown in the graph are infinity and zero i.e. option 2.

What is a discontinuous function?

Discontinuous functions are functions that do not have a continuous curve - there is a hole or jump in the graph.

In the shown graph of the function, the function is discontinuous at x=-3

[tex]\lim_{x \to \ -3} g(x)[/tex] tends to infinity so [tex]\lim_{x \to \ -3} g(x)[/tex] does not exist.

[tex]\lim_{x \to \ +3} g(x)=0[/tex]

Hence, the one-sided limits around the discontinuity shown in the graph are infinity and zero i.e. option 2.

Ok if you look at the figure, it is a vertical angle. This means that the angle opposite to each other is congruent.

m<1 is congruent to m<3

m<2 is congruent to m<4

m<3 is 60⁰ and is congruent to m<1. This means that m<1 is 60⁰. m<4 is 30⁰ and is congruent to m<2. This means that m<2 is 30⁰.

m<1 = 60⁰

m<2 = 30⁰

m<3 = 60⁰

m<4 = 30⁰
