Answer:

36

Step-by-step explanation:

a² + b² = c²

a² + 77² = 85²

a² + 5929 = 7225

a² = 1296

a = 36

Step-by-step explanation:

Answer:

17 x^2

Step-by-step explanation:

(8x^2 + 8x) – (-9x^2 + 8x)

Distribute the minus sign

8x^2 + 8x + 9x^2 - 8x

Combine like terms

17 x^2 +0x

17x^2

Answer:

17x^2

Step-by-step explanation:

(8x^2 + 8x) – (-9x^2 + 8x) =

The parentheses on the left side are unnecessary, so just remove them.

= 8x^2 + 8x – (-9x^2 + 8x)

To remove the right set of parentheses, distribute the negative sign.

= 8x^2 + 8x + 9x^2 - 8x

Now combine like terms.

= 8x^2 + 9x^2 + 8x - 8x

= 17x^2

Answer:

B. 10

Step-by-step explanation:

By the property of intersecting secants outside of a circle:

MN*MA = ML*MK

(x - 4) (x - 4 + 3) = (x - 5) (x - 5 + 6)

(x - 4) (x - 1) = (x - 5) (x + 1)

[tex] x^2 - 5x + 4= x^2 - 4x - 5[/tex]

[tex] - 5x + 4= - 4x - 5[/tex]

[tex] 5 + 4= 5x - 4x [/tex]

[tex] 9 = x [/tex]

KM = x - 5 + 6 = 9 - 5 + 6 = 10

Answer: D. 20ft

Step-by-step explanation:

Answer:

The answer would be 20 feet.

Step-by-step explanation:

This is because square feet is referring to the area. And since the area = L * W and since the sides of the square are identical. It would be 20*20=400.

Answer:

x = 28

Step-by-step explanation:

Given a line parallel to a side of a triangle and intersecting the other 2 sides, then it divides the sides proportionally, that is

[tex]\frac{AC}{CR}[/tex] = [tex]\frac{AD}{DR}[/tex] , substitute values

[tex]\frac{10}{x}[/tex] = [tex]\frac{15}{42}[/tex] ( cross- multiply )

15x = 420 ( divide both sides by 15 )

x = 28

Answer:

x=9

Step-by-step explanation−4(2x−1)=−6(x+2)−2

(−4)(2x)+(−4)(−1)=(−6)(x)+(−6)(2)+−2(Distribute)

−8x+4=−6x+−12+−2

−8x+4=(−6x)+(−12+−2)(Combine Like Terms)

−8x+4=−6x+−14

−8x+4=−6x−14

Step 2: Add 6x to both sides.

−8x+4+6x=−6x−14+6x

−2x+4=−14

Step 3: Subtract 4 from both sides.

−2x+4−4=−14−4

x=9

Answer:

2

Step-by-step explanation:

This is our equation-

-4(2x-1)=-6(x+2)

We are trying to isolate x in a side, but first, we must multiply the numbers in between the brackets. A negative number multiplied by a positive number gives a negative number, and a negative times a negative is positive, so-

-8x·4=-6x+(-12)

Now we have to multiply -8x times 4

-32x=-6x-12

Now we isolate x-

-24x=-12

We divide and get the final result of x=2

x=2

Answer:

You can't solve for f since f is eliminated from the equation.

Step-by-step explanation:

f = d + e + f

Subtract f from both sides.

0 = d + e

You can't solve for f since f is eliminated from the equation.

D. 3,552.00

Step-by-step explanation:

Answer:

3 bottles

Step-by-step explanation:

Hello!

First, we find out how many fluid ounces 25 cups of juice hold.

One cup holds 12 fluid ounces so to find 25 we do

25 * 12 = 300 fluid ounces

Next, we find out how many fluid ounces one gallon holds.

One gallon is 4 quarts.

1 quart is 32 fluid ounces so to find how many 4 holds we do

32 * 4 = 128

So one gallon holds 128 fluid ounces

To find how many we need we divide the total needed by how much one bottle holds

300/128 = 2.34

You can't buy exactly 2.34 bottles of juice so we round up to the nearest whole number we will just have extra leftover

The answer is 3 bottles

Hope this helps!

Answer:

x≥2

Step-by-step explanation:

First, write out the equation as you have it:

[tex]58-10x\leq20+9x[/tex]

Then, add [tex]10x[/tex] to both sides:

[tex]58-10x+10x\leq20+9x+10x\\58\leq20+19x[/tex]

Next, subtract [tex]20[/tex] from both sides:

[tex]58-20\leq20-20+19x\\38\leq19x[/tex]

Finally, divide both sides by [tex]19[/tex]:

[tex]\frac{38}{19}\leq\frac{19x}{19}\\2\leq x[/tex]

or

[tex]x\geq 2[/tex]

Therefore: the answer to this inequality/equation is: x≥2

Answer: C. 324 cm∧3

Just took quiz.

Based on the calculations, the volume of this pyramid is equal to: D. 324 cm³.

Given the following data:

Mathematically, the volume of a pyramid can be calculated by using this formula:

Volume = 1/3 × base area × height

Next, we would find the height of this pyramid from the right-angled triangle ABC by applying Tan trigonometry formula:

Tanθ = Opp/Adj = BC/AC

Tan60 = height/6

√3 = height/6

Height = 6√3 cm.

Now, we can calculate the volume of this pyramid:

Volume = 1/3 × base area × height

Volume = 1/3 × 54√3 × 6√3

Volume = 1/3 × 972

Volume = 324 cm³.

Answer:

Step-by-step explanation:

To find the length of AB we use the formula

[tex] \sqrt{ ({x _{1} - x_{2}})^{2} + ({y_{1} - y_{2} })^{2} } [/tex]

Where

(x1 , y1) and (x2 , y2) are the points

From the question

A is (4 , 5) B is (2 , 2)

So the length of AB is

[tex] |AB| = \sqrt{ ({4 - 2})^{2} + ({5 - 2})^{2} } [/tex]

[tex] |AB| = \sqrt{ {2}^{2} + {3}^{2} } [/tex]

[tex] |AB| = \sqrt{4 + 9} [/tex]

We have the final answer as

[tex] |AB| = \sqrt{13} [/tex]

Hope this helps you

Answer:

sqrt(13) = c

Step-by-step explanation:

The length of BC = 4-2 =2

The length of AC = 5-2 =3

We can use the Pythagorean theorem

a^2 + b^2 = c^2

2^2 + 3^2 = c^2

4+9 = c^2

13 =c^2

Take the square root of each side

sqrt(13) = c

Answer: The equation that has resulted from this is 5x - 6.

Step-by-step explanation:

So far, we know that the givens are:

fives times a number and the difference of 6

Then, we can conclude that the term "a number" means an unknown term, so all we have to do is put a variable in its place. It can be k, s, h, z, x, etc. Next, just find the difference of 6. So, from what we know, this is what our new equation looks like:

5 times ( a number) - the difference of 6

In math form:

5 (x) - 6

Simplify:

5x - 6

Hence the answer!

Answer:

36º

Step-by-step explanation:

Since all the angles are in a ratio, and all angles add up to 360º, we can set up a simple equation to find the smallest angle.

2x + 5x + 6x + 7x = 360

20x = 360

x = 18

18 is NOT the answer since the smallest angle has a ratio number of 2. So we multiply 18 with 2 to get 36º.

Step-by-step explanation:

The four angles of a quadrilateral add to 360

2:5:6:7

Multiply by x

2x:5x:6x:7x

Add them together to get 360

2x+5x+6x+7x = 360

20x = 360

Divide each side by 20

20x/20 = 360/20

x =18

The smallest angle is 2x

2*18 = 36

Answer:

30 miles

Step-by-step explanation:

1/4 = 2

3  3/4 = x

15/4 = x

So, Cross multiply

=> 1/4 * x = 15/4 * 2

=> 1/4x = 15/4 * 4/2

=> 1/4x = 60/8

=> 1/4x = 7.5

=> 1/4x * 4 = 7.5 * 4

=> x = 30

So, 15/4 inches on the map equals 30 miles.

Answer:   [tex]a_n=6n-2[/tex]

Step-by-step explanation:

a₁, ____, 16, ____, a₅, _____, a₇

The difference of a₇ and a₅ is 2d (two steps to the next term).

It is given that 2d = 12  --> d = 6

We can subtract 6 from a₃ to find a₁

a₁ = 4, 10, 16, ____, a₅, _____, a₇

Input a₁ = 4, d = 6 into the explicit formula for an arithmetic equation.
