Stefan sells Jin a bicycle for $115 and a helmet for $17. The total cost for Jin is 110% of what
Stefan spent originally to buy the bike and helmet. How much did Stefan spend originally? How
much money did he make by selling the bicycle and helmet to Jin?

Answers

Stephan spent $145.20 I believe because 115+17=132 and to make it easier, 10% of 132 is 13.2(it’s like multiplying 132 by 0.1) and 100% of 132 is 132 so then you just take 132 and add 13.2 to get $145.20 and how much money he made would be $13.20
Stephan spent $145.20

If Danny gains 40 yards on the football field and then looses 15, What was the end result?

Answers

Answer:

25 yards

Step-by-step explanation:

Subtract 15 from 40.

Hope this helped :)

Answer:

25 yards

Step-by-step explanation:

Arithmetics

Imagine a straight line divided into 1-yard marks.

Danny runs for 40 marks and locates at mark 40.

He later loses 15 yards and his new position is 40 - 15 = 25 yards

Therefore, the end result is that Danny is at the 25-yard mark.

Eugene ate 20% of the Christmas cookies his

many are left?

Answers

Answer:

There are 32 cookies left

Step-by-step explanation:

There are c cookies when we started

c* 20% = 8 cookies

Change to decimal form

c * .20 = 8

Divide each side by .2

c * .2 / .2 = 8/.2

c =40

There are 40 cookies when we started

40 -8 = 32

There are 32 cookies left

Rhombus JKLM with vertices J(-4,7), K(0,8), L(-1, 4), and M(-5,3): (x, y) ------> (x + 2, y - 2)

Answers

Answer:

J'(-2, 5), K'(2, 6), L'(1, 2) and M'(-3, 1)

Step-by-step explanation:

Transformation is the movement of a point from its initial location to a new location. Types of transformation is reflection, rotation, dilation and translation.

Translation is the movement of a point either up, down, left or right on the coordinate plane. If a point A(x,y) is translated a units right and b units up, the new point is at A'(x + a, y + b) while a point A(x,y) is translated a units left and b units down, the new point is at A'(x - a, y - b).

Rhombus JKLM has vertices at J(-4,7), K(0,8), L(-1, 4), and M(-5,3). If a transformation of (x, y) ------> (x + 2, y - 2) is done, i.e. 2 units right and 2 units down, the new points would be at:

❁ Question : Simplify :

[tex] \sf{( {x}^{a} ) ^{b - c} \times ( {x}^{b} ) ^{c - a} \times ( {x}^{c} )^{a - b}} [/tex]

❁ Solution :

First , Use power law of indices.

Remember : If [tex] \sf{ {a}^{m} }[/tex] is an algebraic term , then

[tex] \sf{( {a}^{m} ) ^{n} } = {a}^{m \times n} = {a}^{mn} [/tex] , where m and n are positive integers.

➝ [tex] \sf{ {x}^{a(b - c)} \times {x}^{b(c - a)} \times {x}^{c(a - b)}} [/tex]

➝ [tex] \sf{ {x}^{ab - ac} \times {x}^{bc - ba} \times {x}^{ca - cb}} [/tex]

Now , Use product law of indices :

Remember : If [tex] \sf{ {a}^{m} }[/tex] and [tex] \sf{ {a}^{n}} [/tex] are the two algebraic terms , where m and n are the positive integers then [tex] \sf{ {a}^{m} \times {a}^{n} = {a}^{m + n}} [/tex]

➝ [tex] \sf{ {x}^{ab - ac + bc - ba + ca - cb}} [/tex]

Since two opposites adds up to zero , remove them :

➝ [tex] \sf{ {x} \: ^{ \cancel{ab} \: - \cancel{ac} \: + \cancel{bc} \: - \cancel{ba} \: + \cancel{ca} \: - \cancel{cb} } }[/tex]

➝ [tex] \sf{ {x}^{0} }[/tex]

Use Law of zero index

Remember : If [tex] \sf{ {a}^{0}} [/tex] is an algebraic term , where a ≠ 0 , then [tex] \sf{ {a}^{0} = 1}[/tex]

➝ [tex] \boxed{ \sf{1}}[/tex]

Someone please explain, it's most of my homework! I already did half the problem! Ellie bought 5 cups of apple juice and 7 sandwiches for $25.00. Jim bought 2 cups of apple juice and 3 sandwiches for $10.50. How much did each cup of apple juice cost? How much did each sandwich cost. I set up the equations 5a+7s=25 and 2a+3s=10.5. How do I solve them?

Answers

Answer:

5 cups of apple juice and 7 sandwiches for a total of 25 bucks Jim bought 2 cups of apple juice and 3 sandwiches for $10.50Now we must form some sort of equation for the following: (1) 5a+7s=25(2) 2a +3s =10.5Let us isolate for one variable 3s= 10.5-2a s= 3.5 -2/3a Plug that into (1)5a + 7 (3.5 -2/3a) = 25 a=1.5 Hence each apple juice cost 1.5 Now we can plug that into (2) to solve for the sandwich costs= 3.5- 2/3(1.5) s=2.5 Rate positively and give brainlist

ill give brainliest

Answers

Answer:

c - 4.3 > 16

(hope this helps)

The inequality representing a number c minus 4.3 is no less than 16 is c - 4.3 > 16.

What is inequality?

The relationship between two values that are not equal is described by inequalities. Equal does not necessarily mean unequal. The "not equal symbol" is typically used to denote that two values are not equal.

As the condition is suggesting c - 4.3 is no less than 16 means it is greater than 16,

So, c - 4.3 > 16

Therefore, the inequality representing a number c minus 4.3 is no less than 16 is c - 4.3 > 16.

The slopes of WX and XZ

Step-by-step explanation:

The singular factor that determines if the parallelogram is a rectangle are the angles at the edges

Mathematically, we can only have a rectangle if there are four right angles with one right angle each at the edges of the rectangle

So, by having the slope of the sides forming the width and that which forms the length, we can deduce if what we have is rectangle given that the slopes will yield a perpendicular product

Hence, the slopes of WX and XZ can be calculated to show this

Susan can swim 105 meters in 70 seconds. At this rate, how far can she swim in 30 seconds?

Answers

Answer:

45 meters per 30 seconds

Step-by-step explanation:

To figure this question out you first gave to find the unit rate of meters per second by dividing 105 by 70.

105 divided by 70 = 1.5

So Susan can swim 1.5 meters per second.

Then we multiply that amount by 30 to find the number of meters she can swim in 30 seconds.

1.5 x 30 = 45 meters

So, in conclusion, Susan can swim 45 meters per 30 seconds
