The unit rate of Jana's ride is 0.3 Miles per minutes

A unit rate means a rate for one of something. We write this as a ratio with a denominator of one. For example, if you ran 70 yards in 10 seconds, you ran on average 7 yards in 1 second. Both of the ratios, 70 yards in 10 seconds and 7 yards in 1 second, are rates, but the 7 yards in 1 second is a unit rate.

The unit rate of Jane's ride is

= 15miles/50minutes

= 0.3miles per minute

therefore the unit rate of Jane's ride is 0.3 miles per minute.

The greatest number of biscuits Habib can make is 25

From the question, we have the following parameters that can be used in our computation:

Habib has 400 g of butter

150 g of sugar

675g of flour

Factor each number to determine the GCF

So, we have

400 = 2 * 2 * 2 * 2 * 5 * 5

150 = 2 * 3 * 5 * 5

675 = 3 * 3 * 3 * 5 * 5

So, we have

GCF = 5 * 5

Evaluate

GCF = 25

Hence, the number of biscuits is 25

Answer: 3 3/8 or 3.375

Step-by-step explanation:

Answer:

3.375

Step-by-step explanation:

The equation of the line that runs through the point (0,-1) and (1,2) in slope-intercept form is y = 3x - 1.

The formula for equation of line is expressed as;

y = mx + b

Where m is slope and b is y-intercept.

From the diagram, the line runs through the point (0,-1) and (1,2).

First, we determine the slope of the line

Slope m = change in y / change in x

Slope m = (2 - (-1)) / (1 - 0)

Slope m = (2 + 1) / (1 - 0)

Slope m = 3/1

Slope m = 3

Next, plug the slope m = 3 and point (0,-1) into the point slope formula.

y - y₁ = m( x - x₁ )

y - (-1) = 3( x - 0 )

y + 1 = 3x - 0

y + 1 = 3x

Subtract 1 from both sides

y + 1 - 1 = 3x -1

y = 3x - 1

Therefore, the equation of the line is y = 3x - 1.

Based on the definition of an angle bisector, the measure of angle WUT is: B. 38°.

An angle bisector is a line, ray or segment that divides an angle into two congruent angles.

Therefore:

m<VUW = m<WUT

Substitute

4x + 6 = 6x - 10

Solve for x

4x - 6x = -6 - 10

Answer: 3 , 4 and 5 are correct options

Step-by-step explanation:

Proportionately, if Hayden uses 4 cups of flour and 5 cups of sugar to make cupcakes, he will eat 20 cupcakes.

Proportion refers to the relative size or ratio of one value compared to another quantity.

Proportions are represented as fractional values with decimals, percentages, or fractions.

The quantity of flour for 1 cupcake = 1/5 cups

The quantity of sugar for 1 cupcake = 1/4 cups

The quantity of flour Hayden uses = 4 cups

The number of cupcakes from 4 cups = 20 (4 ÷ 1/5)

The quantity of sugar Hayden uses = 5 cups

The number of cupcakes from 5 cups of sugar = 20 (5 ÷ 1/4)

Thus, according to the proportion of cupcake ingredients to the available quantities of ingredients, Hayden will make and eat 20 cupcakes.

Since ΔABC and ΔACD are similar triangles, therefore the length of AC is 18 m.

Similar triangles are triangles with corresponding sides that have the same ratio.

Thus:

AD is parallel to BC (bases of a trapezoid are parallel)

Therefore:

∠ACB = ∠CAD (alternate interior angles)

This implies that, ΔABC ~ ΔACD by AA similarity theorem.

Thus:

AC/DA = CB/AC

Substitute

AC² = 12 × 27

AC = √324

AC = 18 m

Answer:

Option B

Step-by-step explanation:

Answer:

To find the GCF of 2^5·5·11 and 2^3·5^2·7, we first prime factorize each number:

2^5·5·11 = 2^5 x 5 x 11

2^3·5^2·7 = 2^3 x 5^2 x 7

Next, we look for the highest power of each prime factor that they both have in common:

2^3 is the highest power of 2 that both numbers have.

5^2 is the highest power of 5 that both numbers have.

So, the GCF of 2^5·5·11 and 2^3·5^2·7 is 2^3 x 5^2 = 180.

Step-by-step explanation:

We know from the problem that l = 3w - 5. We also know the formula for area is A = w * l. Therefore, the area of the rectangle is A = w * (3w - 5). We can then set this equation equal to 50 as the question states and solve for w.

[tex]50 = w * (3w-5)[/tex]

Expand the multiplication

[tex]50 = 3w^{2}- 5w[/tex]

Subtract 50 from both sides.

[tex]0 = 3w^{2} - 5w - 50[/tex]

We now have a quadratic equation and can solve it using the quadratic formula to find w. We find that the solutions to the equation are 5 and -3.3. We know that the width can't be negative, so the width must be 5.

Finally, we can plug this solution into the length formula we found earlier to solve for length.

[tex]l = 3w - 5[/tex]

Plug in the solution to w.

[tex]l = 3(5) - 5[/tex]

Multiply 3 and 5.

[tex]l = 15-5[/tex]

Subtract 5

[tex]l = 10[/tex]

Therefore the width is 5 and the length is 10.

Regarding shopping for a new card, it would depend on the terms and conditions of the new card, including the annual interest rate and any fees. Rachel should compare the options available and weigh the benefits and drawbacks of each before making a decision.

The length of time it will take Rachel to pay off her credit card balance can be calculated by dividing the outstanding balance by the monthly payment amount and then adding the number of months needed to pay off the balance.

Balance = $8,281

Monthly payment = $250

Annual interest rate = 16%

To calculate the length of time it will take to pay off the balance, we would first need to calculate the monthly interest rate, which can be done by dividing the annual interest rate by 12:

Monthly interest rate = 16% / 12 = 1.33%

Next, we can calculate the monthly payment amount, including the interest:

Monthly payment amount = $250 + ($8,281 * 1.33%)

By continually subtracting the monthly payment amount from the balance and adding the monthly interest, we can determine the length of time it will take to pay off the balance.

If Jane took 30 min to drive her boat upstream to water-ski at her favorite spot. her boat speed in still water is;3 km/h.

Let's x represent the  Jane's boat speed in still water

Upstream, her speed was x - 2 km/h.

Downstream, her speed was x + 2 km/h.

Let's d represent the distance between the start and end point

Let the  time it takes to cover d at a speed of x - 2 km/h=  30 min.

Let the  time it takes to cover d at a speed of x + 2 km/h=  10 min.

So we have:

d / (x - 2) = 30 min and

d / (x + 2) = 10 min.

Multiplying both sides of each equation

d * x - 2d = 30 * (x - 2)

d * x + 2d = 10 * (x + 2).

Adding the two equations and solve for x

2d * x = 40 * x + 20

20 * x = 40 * x + 20

20 * x = 60 * x

x= 3 km/h

the equation of the tangent line to the curve y = 2 sin x at the point (π/6, 1) will be y = √3 x + 0.093.

A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are included. Sometimes, the aforementioned is referred to as a "linear equation of two variables," with y and x serving as the variables.

y = mx + b

1) m = slope of the tangent line = derivative at the point (pi/6, 1)

Function: y = 2sinx

Derivative: y ' = 2cosx

evaluate at x = pi/6=> y ' = 2cos(pi/6) = √3

2) equation using the slope and the point (pi/6, 1)

y - 1 = √3 ( x - pi/6 )

y = √3 x - √3(pi/6) +1 =√3 x + 0.093

y = √3 x + 0.093

m = √3, b = 0.093

Therefore, y = √3 x + 0.093 will be the equation of the tangent line to the curve y = 2sin x at point (π/6, 1).
