3. Mrs. Sinclair is finding the selling price of a pair of $40
skates with a 30% markup. Find her mistakes and correct it.

Answers

Answer 1

Answer:

Selling price : $52

Step-by-step explanation:

First, find 30% out of 40.

x= (40)(30)=1200/ 100= 12

x=12

Add 30% to the original selling price.

So then you add $12 to $40 to get $52.

Help what is the answer ?? What is the is the translation coordinate

Answers

Answer: (x - 3, y - 6) or S(-5 -3, 6 -6)

First we have to figure out how many spaces left to right (x-axis) and how many spaces up and down (y-axis) will get us to S'

x-axis: -5 - 3 = -8

y-axis: 6 - 6 = 0

Now we just add this to the original coordinate to give us the translation coordinate:

S(-5, 6) → S(-5 -3, 6 -6)

What is the value of x in a 45-45-90 triangle and the hypotenuse is 4?

Answers

9514 1404 393

Answer:

  x = 2√2 ≈ 2.83

Step-by-step explanation:

The side length of an isosceles right triangle is 1/√2 times the hypotenuse length. If x is the side length, then ...

  x = 4/√2 = 4(√2)/2

  x = 2√2 ≈ 2.83

You have not specified the form of the answer. Sometimes an exact answer (2√2) is required. Sometimes the answer is required to be rounded to tenths or hundredths.

Can someone please help me with this questions The points H,I,J and K all lie on the same line segment, in that order, such that the ratio of HI:IJ:JK is equal to 2:2:3. If HK=49, find IJ.

Answers

Answer:

IJ = 14

Step-by-step explanation:

If the point HIJK all lies on the same line, then HI + IJ + JK = HK

2 + 2 + 3  = HK

HK = 7

Since the total length is HK

IJ = ratio of IJ/Total ratio * HK

IJ = 2/7 * 49

IJ = 2 * 7

IJ = 14

Hence the length of IJ is 14

what connections can you make between polynomial equations and roots of a graph

Answers

Answer:

Factors of a polynomial, when set equal to zero and solved, become the zeros of a polynomial.  

The zeros of a polynomial are the numbers where the y-values are 0 which means the point will lie on the x-axis.  

Zeros and solutions are the same things. It is where the graph will cross the x-axis which means the y-value is zero.

An isosceles triangle has base angles that each measure 39 °. Which equation can be used to fi nd t, the measure of the third angle of this isosceles triangle in degrees?

Answers

Answer: 102°

Step-by-step explanation:

First and foremost, we should note that an isosceles triangle has two sides that are equal and that the sum of angles in a triangle equals to 180°.

Since we are told that the isosceles triangle has base angles that each measure 39°, the third angle will be:

t + 39° + 39° = 180°

t + 78° = 180°

t = 180° - 78°

t = 102°

The third angle is 102°.

A snowcone with a radius of 4 cm is sold in a cone-shaped paper cup with a height of 12 cm and an opening 6 cm wide. If all the ice melted in the cup, would it overow?

Answers

Answer: No because when you do the volume of the cone is r=3cm h=12cm and the sphere is r=4cm

If the ice melt in the cone shaped cup, it won't overow because the volume of the cone shaped cup is greater than the volume of the snowcone ice.

The snowcone is a sphere.

Volume of a sphere

volume = 4 / 3πr³

where

r = radius

Therefore,

volume of the snowcone = 4 / 3 × π × 4³

volume of the snowcone = 256 π/ 3 = 85.33π

Therefore, the volume of the cone canbe found as follows:

volume of the cone shaped paper = 1 / 3 πr²h

h = 12 cm

r = 6cm

volume of the cone shaped paper = 1 / 3 × π × 6² × 12

volume of the cone shaped paper = 144π

Therefore, let find if the ice melt in the cone whether it will overow.

144π - 85.33π = 58.67π

Therefore, the volume of the cone shaped paper is greater than the volume of the snowcone ice . This means that if the ice melt in the cup , it won't overow.

is 25. What are the two numbers?
Can you please send the work too

Answers

Step-by-step explanation:

this is simple use it and enjoy

Step-by-step explanation:

Let x be the first number

Let y be the 2nd number

given,

[tex]x = 3y - 11 \\ x - 3y = - 11[/tex]

as equation 1

and

[tex]x + y = 25[/tex]

as equation 2.

Now we will use elimination method to solve for simultaneous equations.

We will use equation 1 - equation 2 to eliminate x to solve for y.

[tex]x - x - 3y - y = - 11 - 25 \\ - 4y = - 36 \\ y = - 36 \div - 4 \\ = 9[/tex]

Substitute y into equation 2.

[tex]x + 9 = 25 \\ x = 25 - 9 \\ = 16[/tex]

The numbers are 9 and 16.
