The length has to be greater than the absolute difference between the other two lengths, but less than the sum of them. In other words, if your unknown side length is a, and the other two are b and c, then its |b - c| < a < b + c

So, putting in your values, you have 10 - 7 < a < 10 + 7, which is 3 < a < 17

So, your range is from 3 to 17 (non inclusive).

The length has to be greater than the difference between the named two lengths, but less than the sum of them. So 3-17 is your answer.

Answer:

The answer is 10

Step-by-step explanation: You multiply the 2 times twenty to get 40 then multiply the 2 times 2x to get 4x then subtract fourty from both sides and you will get fourty and then divide so 40 divided by 4x equals 10.

Answer:

x=10

Step-by-step explanation:

2x20=40 and 2x2x=4x move the 40 to the other side so 80-40=40 so 4x=40 4x10=40 so 10 should be correct.

Answer:

A) 288 [tex]cm^{3\\}[/tex]

Step-by-step explanation:

The Volume of the figure is 288 cm³.

Volume is a three-dimensional quantity used to calculate a solid shape's capacity. That means that the volume of a closed form determines how much three-dimensional space it can fill.

Given:

Base edges = 4 cm x 4 cm

Height = 1 cm

So, Volume = area of the base x height

For Figure 1:

Volume of figure1

=(4x4)x 10

=160

For Figure 2:

Volume of figure 2

= (8x4) x 4

= 128

Thus, the Total volume = 160+ 128 =288 cm³

Answer:

x = 7.6

Step-by-step explanation:

Label the values you have on the triangle: The X is opposite, the 33 is your theta (ø) and 14 is your hypotenuse

Plug these values into the equation sin(ø)=o/h making the equation sin(33)=x/14.

Take the 14 and multiply it on the opposite side, making the equation look like this: 14xsin(33)=x

Then plug this into the TI-83/84 calculator and make sure it is degree mode (mode, degree)

Then just round to the nearest tenth. :)

Answer:

432

Step-by-step explanation:

Volume of cuboid:

12 x 4.5 x 5.5 = 297

volume of traingular prism:

(12x5)/2 x 4.5 =135

add them together:

135+297 =432

hope this helps!

So, the required volume of the given wooden block is 432 cubic cm.

The formula for the volume of the rectangular prism is,

[tex]v=l\times b \times h[/tex]

And the formula for the volume of the triangular prism is,

[tex]v=\frac{1}{2} \times b \times h[/tex]

It is given that,

The volume of the wood is equal to the volume of the rectangular prism and triangular prism.

So, by using the above formula we can write as,

The volume of the wood is,

= volume of the wood is equal to the volume of the rectangular prism + triangular prism.

[tex]=l\times b\times h+\frac{1}{2}\times h\times l\\ =12\times 4.5 \times 5.5 +\frac{1}{2} \times 12\times 4.5 \times 5\\=297+135\\=432 cm^3[/tex]

Answer:10.35 dollars

Step-by-step explanation: 15% of 9 dollars is 1.35

so you add 1.35 to 9 dollars to find the total cost

The total cost she will have to pay for the toy is $10.35.

A percentage is a figure or ratio that can be stated as a fraction of 100. If we need to calculate the percentage of a number, we must divide it by its full value and then multiply it by 100. As a result, the percentage is one part in one hundred. "Per 100" is short for "per percent." It is represented by the symbol "%".

Given the cost of the toy = $9

sale tax on toy = 15% of the total price

sale tax on toy = 15% of 9

sale tax on toy =  0.15 x 9

sale tax on toy = $1.35

total  cost to pay = $9 + $1.35

total  cost to pay = $10.35

Hence total cost to pay is $10.35.

2. The equation of the line can be written in the slope form of y=mx+c where m is the gradient of the line and c is the y-intercept

Taking points on the line ; (-2,-2) and (2,0) the gradient m is ;

Step-by-step explanation:

Given

x² - 5x - 14

Consider the factors of the constant term (- 14) which sum to give the coefficient of the x- term (- 5)

The factors are + 2 and - 7, since

2 × - 7 = - 14 and 2 - 7 = - 5, thus

x² - 5x - 14 = (x + 2)(x - 7)

Answer:

Step-by-step explanation:

XY=ST/2

3z+2=(7z-1)/2

2*(3z+2)=7z-1

2*3z+2*2=7z-1

6z+4=7z-1

+1         +1

6z+5=7z

-6z      -6z

5=z

The required value of z is 5.

Given that,

In RST, X is the midpoint of RS,

And Y is the midpoint of RT.

XY = 3z + 2 and ST = 7z - 1.

We have to determine,

What is the value of z.

According to the question,

X is the midpoint of RS,

And Y is the midpoint of RT.

Therefore,

[tex]XY = \frac{ST}{2}[/tex]

Putting the value of XY and ST in the equation,

XY = 3z + 2 and ST = 7z - 1.

Then,

[tex]XY = \frac{RS}{2} \\\\3z+ 2 = \frac{7z-1}{2}\\\\2 \times(3z+2) = 7z-1\\\\= 6z+4= 7z-1\\\\6z-7z = -1-4\\\\-z = -5\\\\= z = 5[/tex]

Hence, The required value of z is 5.

Answer:

r = 10

Step-by-step explanation:

C = 62.8 = 2π·r

62.8 = 2·3.14·r

r = 62.8/2·3.14

= 31.4/3.14

= 10

Answer:

10 miles

Step-by-step explanation:

The circumference of a circle can be found using:

[tex]c=2r\pi[/tex]

We know circumference is 62.8, so we can substitute it in

62.8=[tex]2r\pi[/tex]

We want to find r, so we have to isolate it.

Divide both sides by [tex]2\pi[/tex] or 2*3.14 which is 6.28

62.8=[tex]2r\pi[/tex]

62.8=6.28r

62.8/6.28=6.28r/6.28

r=10

So, the radius is 10 miles

Answer:

  -17

Step-by-step explanation:

Each term in the sequence is 5 less than the one before, so the first 4 terms are ...

  -2, -7, -12, -17

The 4th term of the sequence is -17.

__

The general term (an) of the sequence can be written as ...

  an = a1 +d(n -1)

where a1 is the first term and d is the common difference. Here, those are ...

  a1 = -2, d = -5

so the general term is ...

  an = -2 -5(n -1)

We can use this to find the 4th term:

  a4 = -2 -5(4 -3)

  a4 = -17
