Can I Get Crown?

Answer: For a shorter Answer here's this 30 + 12.5x >= 135

X >= 8.4 points

Step-by-step explanation:

30 + 12.5x > = ( more or equal) 135

12.5x >= 135 - 30

12.5x >= 105

X >= 105/12.5

X >= 8.4

Step-by-step explanation:

The inequality determines the number of visits Nevaeh can make to earn her first free movie ticket.

30 + 12.5v ≥ 135

The number of visits must be 9 or greater.

What is inequality?

It shows a relationship between two numbers or two expressions.

There are commonly used four inequalities:

Less than = <

Greater than = >

Less than and equal = ≤

Greater than and equal = ≥

We have,

Signing up rewards points = 30

Points for each visit = 12.5

Minimum points required for a free movie ticket = 135

Let the number of visits = v

Now,

The inequality that determines the number of visits Nevaeh can make to earn her first free movie ticket.

30 + 12.5v ≥ 135

Solve for v.

30 + 12.5v ≥ 135

12.5v ≥ 135 - 30

12.5v ≥ 105

v ≥ 105/12.5

v ≥ 8.4

This means that,

The number of visits must be greater than or equal to 9.

We can cross-check.

30 + 12.5 x 9

30 + 112.5

142.5

Thus,

The inequality that determines the number of visits Nevaeh can make to earn her first free movie ticket.

30 + 12.5v ≥ 135

The number of visits must be 9 or greater.

Step-by-step explanation:

hello help me with this question thanks in advance​

Answers

[tex]\bold{\huge{\underline{ Solution \:1}}}[/tex]

Here, We have given

The sides of a triangle are 8 , 15 and 18 The one of the side of the similar traingle is 10.

Let assume the given triangle as ΔABC and ΔXYZ

According to the similarity theorem

If two triangle's are similar then the ratio of their corresponding sides are also equal .

Therefore, By using above theorem :-

[tex]\sf{\dfrac{ A}{X}}{\sf{=}}{\sf{\dfrac{ B}{Y}}}{\sf{=}}{\sf{\dfrac{ C}{Z}}}[/tex]

Subsitute the required values

[tex]\sf{\dfrac{ 8}{10}}{\sf{=}}{\sf{\dfrac{ 15 }{Y}}}{\sf{=}}{\sf{\dfrac{18}{Z}}}[/tex]

For other two sides of another similar triangle

[tex]\sf{\dfrac{ 8 }{10}}{\sf{=}}{\sf{\dfrac{ 15}{Y}}}[/tex]

[tex]\sf{Y =15}{\sf{\times{\dfrac{ 10}{8}}}}[/tex]

[tex]\sf{Y =15}{\sf{\times{\dfrac{ 5}{4}}}}[/tex]

[tex]\sf{Y = }{\sf{\dfrac{ 75}{4}}}[/tex]

[tex]\bold{Y = 18.75 }[/tex]

And,

[tex]\sf{\dfrac{ 8 }{10}}{\sf{=}}{\sf{\dfrac{ 18}{Z}}}[/tex]

[tex]\sf{Z =18 }{\sf{\times{\dfrac{ 10}{8}}}}[/tex]

[tex]\sf{Z =18}{\sf{\times{\dfrac{ 5}{4}}}}[/tex]

[tex]\sf{Z = }{\sf{\dfrac{ 90}{4}}}[/tex]

[tex]\bold{Z = 22.5 }[/tex]

Hence, The two sides of the another similar triangle is 18.75 and 22.5

[tex]\bold{\huge{\underline{ Solution \:2}}}[/tex]

Here, We have

Two similar triangles Whose sides are 4 , 12 ,20 and 5 , 15 , 25

Let assume the two triangle be ΔABC and ΔPQR

According to the similarity theorem :-

If two triangle's are similar then the ratio of their corresponding sides are also equal .

That is,

[tex]\sf{\dfrac{ A}{P}}{\sf{=}}{\sf{\dfrac{ B}{Q}}}{\sf{=}}{\sf{\dfrac{ C}{R}}}[/tex]

Subsitute the required values,

[tex]\sf{\dfrac{4 }{5}}{\sf{=}}{\sf{\dfrac{ 12}{15}}}{\sf{=}}{\sf{\dfrac{ 20 }{25}}}[/tex]

[tex]\sf{\dfrac{4 }{5}}{\sf{=}}{\sf{\cancel{\dfrac{ 12}{15}}}}{\sf{=}}{\sf{\cancel{\dfrac{ 20 }{25}}}}[/tex]

[tex]\bold{\dfrac{4 }{5}}{\sf{=}}{\bold{\dfrac{ 4}{5}}}{\sf{=}}{\bold{\dfrac{ 4 }{5}}}[/tex]

Hence, The scale factor of the given similar triangles is 4/5

[tex]\bold{\huge{\underline{ Solution \: 3}}}[/tex]

Here, we have given that

A map in Davao City has a scale factor of 1 cm to 0.5 kmThat is, 1 : 0.5

But,

We have to find the distance corresponds to an actual distance of 12 km.

Therefore,

According to the scale factor

The actual distance will be

[tex]\sf{=}{\sf{\dfrac{ 12 }{0.5}}}[/tex]

[tex]\bold{ = 24 \: km }[/tex]

Hence, The map distance corresponds to actual distance of 12 km is 24 km.

#3 Answer:

The other sides are 18.75 and 22.5

#3 Step-by-step explanation:

Because of the similar triangle

So, [tex]\frac{8}{10}=\frac{15}{x}=\frac{18}{y}[/tex]               [tex]\left\{The\ corresponding\ sides\ are\ proportional\right\}[/tex]

[tex]x=18.75,\ y=22.5[/tex]

#4 Answer:

[tex]\sf y =6[/tex]

[tex]\sf x =3[/tex]

Step-by-step explanation:

[tex]\sf y = \frac{2}{3} x+4[/tex]

[tex]\sf 2x+3y = 24[/tex]

make y the subject in equation 2:

[tex]\sf 2x+3y = 24[/tex]

[tex]\sf 3y = 24-2x[/tex]

[tex]\sf y = \frac{24-2x}{3}[/tex]

insert this in equation 1:

[tex]\sf \frac{24-2x}{3} =\frac{2}{3} x+4[/tex]

[tex]\sf \sf \frac{24-2x}{3} =\frac{2x+12}{3}[/tex]

[tex]\sf (24-2x) = (2x+12)[/tex]

[tex]\sf -2x-2x=12-24[/tex]

[tex]\sf -4x=-12[/tex]

[tex]\sf x =3[/tex]

solve for y:

[tex]\sf y = \frac{24-2(3)}{3}[/tex]

[tex]\sf y =6[/tex]

Answer:

Step-by-step explanation:

[tex]\textsf{Equation 1}: \ y=\dfrac23x+4[/tex]

[tex]\textsf{Equation 2}: \ 2x + 3y =24[/tex]

Substitute equation 1 into equation 2:

[tex]\implies 2x + 3\left(\dfrac23x + 4 \right) =24[/tex]

Expand brackets:

[tex]\implies 2x +2x+12=24[/tex]

Collect like terms:

[tex]\implies 4x+12=24[/tex]

Subtract 12 from both sides:

[tex]\implies 4x=12[/tex]

Divide both sides by 4:

[tex]\implies x=3[/tex]

Now substitute found value of x into equation 1:

If f(3) = 12 and f '(x) ≥ 3 for 3 ≤ x ≤ 5, how small can f(5) possibly be?

Answers

Answer:

18

Step-by-step explanation:

Since f '(x) ≥ 3, that means for every x, it can increase by 3 or greater. If we want to find the smallest f(5), we have to use the smallest rate of change possible, which is just 3.

Then, we have to find how many times x changes. Since we are going from 3 to 5, that means x changes 2 times. (5 - 3 = 2)

Now we multiply the rate of change (3) by the number of x changes.

3 x 2 = 6

We then add that to 12 since that is the number we started with

12 + 6 = 18

Find the value of xx, yy, and zz in the parallelogram below.

Answers

Answer: x = 92, y = -119

Step-by-step explanation:

Opposite sides of a parallelogram are equal.

x + 6 = 98

x = 92

127 = -y + 8

-y = 119

y = -119

Opposite sides and opposite angles of a parallelogram are equal and consecutive sides have sum 180

-y+8=127-y=127-8-y=119y=-119

And

x+6=98x=98-6x=92

A 96cm A long wire is given the shape of a rectangle such that its length is 12 cm more than its breadth Find the dimensions of the rectangle.​

Answers

Answer:

The length of the rectangle is 30 cm, and the width of the rectangle is 18 cm.

Step-by-step explanation:

Since the wire is shaped as a rectangle, and we need perimeter for this problem, we can use the equation (l+w)*2, and the perimeter is 96, where l is the length and w is the width.

Since the length is 12 cm longer than the width, then we have:

W + 12 = L

Now substitute for the L in our equation and solve.

(w+12+w)*2 = 96

(2w + 12) *2 = 96

Multiply using the distributive property

4w + 24 = 96

4w = 72

w = 18

Now plug in the w for our second equation:

18 + 12 = L

30 = L

Now check our answer by plugging it in our old equation:

(18+30)*2 = 96

48*2 = 96

96 = 96

Our answer is correct, so the length of the rectangle is 30 cm, and the width of the rectangle is 18 cm. Hope this helps.

which of the following measurements could be the side lengths of a right triangle?

Answers

Answer:

Option A

Step-by-step explanation:

Here we need to tell which could be the side lengths of a right angled triangle . As we know that in a right angled triangle , the sum of square two sides along the right angle is equal to the square of side opposite to right angle .

That is ,

[tex]\longrightarrow a^2 = b^2+ c^2 [/tex]

[tex]\begin{picture}(8,8)\setlength{\unitlength}{1cm} \thicklines\put(0,0){\line(1,0){4}}\put(4,0){\line(0,1){3}}\put(4,3){\line(-4,-3){4}}\put(2,-0.5){$\sf \sqrt{48}in$}\put(4.4,1.5){$\sf \sqrt{12}in. $} \put(1.2,2){$\sf \sqrt{60}in. $}\end{picture}[/tex]

We can start by looking at the options , first option is ,

[tex]\longrightarrow \sqrt{48}\ in , \sqrt{12}\ in , \sqrt{60} in [/tex]

So by squaring first two sides and adding them , we have ,

[tex]\longrightarrow (\sqrt{48})^2+(\sqrt{12})^2\\[/tex]

[tex]\longrightarrow 48+12 = 60[/tex]

And by squaring the third side we have ,

[tex]\longrightarrow \sqrt{60}^2 = 60 [/tex]

Hence here the sum of square of two sides is equal to the square of third side .

Therfore the triangle with sides 48 in , 12in and 60 forms a right angle .

Hello!

First, let's list an important conversion. 1 pound = 16 ounces.


For the sake of this explanation, and because I think this is mathematically easier to deal with, we are going to be dealing in ounces.


So, step one, convert 5 pounds to ounces. For this, we just multiply 5 by 16 to get 80.

Now, we know each package of carrots weighs 14 ounces each. Since we need to see how many times 14 goes into 80 (remember, 80 is the same as 5 pounds), we use division.

80/14 = 5[tex]\frac{5}{7}[/tex]

But, hey! You can/t buy 5/7ths of a package. So we need to buy an ENTIRE EXTRA PACKAGE just to make up for it.

So we round our number up to 6.
