In a marketplace, a box of peaches can be purchased for $77.95 per box. One box
contains 78 peaches. How much would you have to pay to buy 4 peaches?
(Hint: Convert 4 peaches into dollars.)
Round your answer to the nearest hundredth. Do not type the units ($) in the space
below.

Answers

Answer:

Step-by-step explanation:

This question can be solved by proportions, using rule of three.

We have that:

You buy 78 peaches for $77.95. How much you pay to buy 4 peaches?

78 peaches - $77.95

4 peaches - x

[tex]78x = 4*77.95[/tex]

[tex]x = \frac{4*77.95}{78}[/tex]

[tex]x = 4[/tex]

You pay $4 for 4 peaches.

What type of transformation transforms (a, b) to (-a, b)?

a reflection over the y-axis
a translation of 1 unit down
a reflection over the x-axis
a translation of 1 unit up

Answers

Answer:

A reflection over the y axis .

Step-by-step explanation:

Given : Transforms (a,b) to (-a,b).

To find : What type of transformation.

Solution : We have given

Parent function : (a,b) .

Transformed : (-a ,b).

solve for x using Logarithm
4^x+6^x =9^x

Answers

4^x + 6^x = 9^x

4^x + 6^x - 9^x = 0

2^2x + (2×3)^x - 3^2x = 0

2^2x + 2^x×3^x - 3^2x = 0

(⅔)^2x + (⅔)^x - 1 = 0

let t = ( ⅔)^x

t² + t - 1 = 0

t = (-1+√5 ) / 2

(⅔)^x = (-1+√5 ) / 2

x = Log base ⅔ ((-1+√5 ) / 2 )

x = 1.18681

Explain the importance of using the square of the scale factor to calculate the area of a dilated figure

Answers

Answer:

Step-by-step explanation:

2+2=4 therefore 2x2 also equals 4, 4/2=2.

In mathematics and geometry, a dilation is an enlargement in size or a reduction in size of a mathematical object. We perform a dilation of a square by placing the shape on a coordinate plane and multiplying each of the coordinates of the vertices of the square by the same number, called the scale factor. This can also be achieved by multiplying the lengths of each of the sides of a square by the scale factor.

When we dilate a square by a scale factor of k, its sides increase by a factor of k, its area by [tex]k^{2}[/tex], and its volume by [tex]k^{3}[/tex].

So, this is the importance of using the square of the scale factor to calculate the area of a dilated figure.

What is Square?

Square, in geometry, a plane figure with four equal sides and four right (90°) angles. A square is a special kind of rectangle (an equilateral one) and a special kind of parallelogram (an equilateral and equiangular one).

What is scale factor?

The scale factor is a measure for similar figures, who look the same but have different scales or measures. Suppose, two circle looks similar but they could have varying radii. The scale factor states the scale by which a figure is bigger or smaller than the original figure.

A line has a slope of -1/10
and includes the points (1, -6) and (t, -5). What is the value of t?

Answers

Answer:

-9

Step-by-step explanation:

Here we use the slope formula: m= y2-y1/x2-x1. We simply plug in the numbers we know: -1/10 = -5+6/t-1. Then we solve for t. Multiply both sides by (t-1) so -1/10 (t-1)= 1. Then multiply both sides by -1/10 so t-1= -10 and then add one to both sides so t=-9.

Rose follows this recipe, but only wants to make 3 fingers.
How much of each ingredient does she need?

Recipe: Makes 18
120 g butter
60 g sugar
180 g flour

Answers

(I don't know if this is the method you are supposed to use, but I believe you will still get the same answer!)

Answer: 20 g butter, 10 g sugar, 30 g flour

Step-by-step explanation: First off, if we look at 3 and 18, you notice that three is a factor or 18, going into the number 6 times.

So, if you are making 6 times less of the original amount, divide each measurement by six to give you your answer.

120/6 = 20

60/6 = 10

180/6 = 30

20g butter
10g sugar

Is the following statement true? Explain.

" For any two angles A and B, cos (A+B)=cos (A)+cos (B) "

Answers

Step-by-step explanation:

We can prove the statement is false by proof of contradiction:

We know that cos0° = 1 and cos90° = 0.

Let A = 0° and B = 90°.

Left-Hand Side:

cos(A + B) = cos(0° + 90°) = cos90° = 0.

Right-Hand Side:

cos(A) + cos(B) = cos(0°) + cos(90°)

= 1 + 0 = 1.

Since LHS =/= RHS, by proof of contradiction,

the statement is false.
