[tex]8x - 1 < 15 \\ 8x < 15 + 1 \\ 8x < 16 \\ x < \frac{16}{8} \\ x < 2[/tex]

Answer:

As Per Given Information

The given equation is 8x-1 <15

Adding both side 1 we obtain

↝ 8x - 1 + 1 < 15 + 1

↝ 8x < 16

Now dividing both side by 8 we obtain

↝ x < 2

So, the required answer is x < 2.

Here, We have given

Let assume the given triangle as ΔABC and ΔXYZ

According to the similarity theorem

Therefore, By using above theorem :-

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]

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 ∆.

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:

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.

Answer:

6 packages.

Put it on the number line by labeling the leftmost point "1," put each point after that going up one number and then plot the point at 6.

Step-by-step explanation:

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.

Answer:

Divide the numerator by the denominator.

Write down the whole number answer.

Then write down any remainder above the denominator.

Let's practice!

56 / 9 = 6 remainder 2

We keep the denominator the same.

6 2/9

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

Answer:

UT = 9.8

Step-by-step explanation:

Given: a geometric problem

Find : net of a cuboid

Solution: net of cuboid is given below

Given: a figure

Find: value of UT

Solution : we know that when secant and a

tangent intersect outside the circle then

(ST + UT) (ST) = RS.RS

=> (9+UT). 9 = 13:13

=> 81 + 9xUT = 169

=> 9x UT = 88 => UT = 88/9 => UT= 9.777

So UT = 9.8

Hence answer is UT = 9.8
