Answer:

x =3.

Step-by-step explanation:

This is an isosceles triangle  so the 2 sides opposite the equal angles are congruent.

So  3x + 2 = 11

3x = 9

x = 3.

Answer:

49 and 2/3

Step-by-step explanation:

3x+2+18+11=180

3x+31=180

3x=149

x=49 and 2/3

Answer:

I'm not sure which you mean, so I'll give the answer to both:

[tex]70 X 10^2 = 7000\\(70x10)^2 = 490000[/tex]

Answer:

You can use our formula for the surface area of a rectangular prism for a cube as well. A cube is a rectangular prism where all its sides are the same. The formula to find the surface area of a rectangular prism is A = 2wl + 2lh + 2hw, where w is the width, the l is the length, and the h is the height.

The answer is 78

Answer:

-12°F o -11°F.

Step-by-step explanation:

We have two statements, which are the following:

- the temperature In Pittsburgh Is -13 ° F

- the temperature in Cleveland Is-10 ° F

Then they tell us, "the temperature in Chicago is higher than the temperature in Pittsburgh"

Which means that the statement that helps us is the first, which is the one that tells us about Pittsburgh, now, a higher number since it is a higher temperature, we know that when a number is negative, the higher the number is , actually the number is less, therefore the temperature should be at least -12 ° F or -11 ° F. That is, anyone with sense between the city's temperature ranges greater than -13.

and for L multiply it by 1000

Answer:

About 188.71 feet

Step-by-step explanation:

The cosine of an angle is equivalent to the adjacent side divided by the length of the hypotenuse. Therefore:

[tex]\cos 58=\dfrac{100}{x} \\\\x=\dfrac{100}{\cos 58}\approx 188.71[/tex]

Hope this helps!

Answer:

x = 188.71

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

cos theta = adjacent/ hypotenuse

cos 58 = 100/x

Multiply by x

x cos 58  = 100

Divide by cos 58

x = 100/cos 58

x =188.7079915

To the nearest hundredth

x = 188.71

Answer:

$51.75

Step-by-step explanation:

15% of 45 or .15*45 will equal $6.75. Then you add that onto the $45 and you'll get your anwser, $51.75.

Step-by-step explanation:

Answer:

The x-coordinate of A is:

a = 6.1

Step-by-step explanation:

For point A:

x-coordinate = a

x-coordinate + y-coordinate = 14

y-coordinate = 14 - x-coordinate

y-coordinate = 14 - a

So point A can be written as (a, 14-a)

Let (a,14) be (x₁,y₁)

Point P can be written as (3a, a²+13a-11)

Let P be (x₂,y₂)

Slope of a line passing through 2 point is given as:

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

where m=7

Substitute all values

[tex]7=\frac{(a^2+13a-11)-(14-a)}{3a-a}\\7=\frac{a^2+13a-a-11-14}{3a-a}\\7=\frac{a^2+12a-25}{2a}\\14a=a^2+12a-25\\a^2-2a-25=0\\a=6.1,a=-4.1[/tex]

As A has only positive coordinates

a = 6.1

Answer:

[tex]\large \boxed{36\sqrt{2}\text{ units}}[/tex]

Step-by-step explanation:

Assume ∆DEF looks like the one below.

We can use Pythagoras' Theorem to find the hypotenuse f.

[tex]\begin{array}{rcl}d^{2} + e^{2} & = & f^{2}\\36^{2} + 36^{2} & = & f^{2}\\f^{2} & = & 2 \times 36^{2}\\f & = & \sqrt{2 \times 36^{2}}\\& = & 36\sqrt{2}\\\end{array}\\\text{The length of the hypotenuse is $\large \boxed{\mathbf{36\sqrt{2}}\textbf{ units}}$}[/tex]

Answer:

26

Step-by-step explanation:

→ Utilise Pythagoras theorem

a² + b² = c²

→ Substitute in the values

10² + 24² = c²

→ Simplify

100 + 576 = c²

→ Simplify further

676 = c²

→ Square root both sides to isolate c

26 = c

Answer:

c = 2500

Step-by-step explanation:

[tex]x^2+100x + c\\x^2+2\times 50\times x + (50)^2\\=x^2+2\times 50\times x + 2500\\=x^2+100 x + 2500\\equating \: it \: with\: \\x^2+100x + c\\we\; find:\\c = 2500[/tex]

Answer:

c = 2500

Step-by-step explanation:

x² + 100x + c  where c = ?

100 x :    100x / 2x = 50

(50)² = 2500

Answer:

a) The graph is a horizontal shift of the parent function 2 units right.

Step-by-step explanation:

Explanation:-

Type of transformation                       Change to co-ordinate point

Vertical translation up 'd' units                   (x,y) →(x ,y+d)

Vertical translation down 'd' units               (x,y) →(x ,y- d)

Horizontal translation left 'c' units               (x,y) →(x-c ,y)

Horizontal translation right 'c' units            (x,y) →(x+c ,y)

Reflection over X-axis                                   (x,y) →(x ,-y)

Reflection over y-axis                                    (x,y) →(-x ,y)

Given graph  f(x)  = √x

The graph is a Horizontal shift of the parent function  '2' units  right

Therefore the transformation of the graph [tex]y = \sqrt{x+2}[/tex]

Answer:

The value of x is -2.

Step-by-step explanation:

First, you have to eliminate the brackets by expanding :

[tex]2(x - 4) = 4(2x + 1)[/tex]

[tex]2x - 8 = 8x + 4[/tex]

Next, you have to move all the like-terms to one side :

[tex]2x - 8 - 8x = 4[/tex]

[tex] - 6x = 4 + 8[/tex]

[tex] - 6x = 12[/tex]

[tex]x = 12 \div ( - 6)[/tex]

[tex]x = - 2[/tex]

Answer:

[tex]x = - 2[/tex]

Step-by-step explanation:

[tex]2(x - 4) = 4(2x + 1) \\ 2x - 8 = 8x + 4 \\ 2x - 8x = 8 + 4 \\ - 6x = 12 \\ \frac{ - 6x}{ - 6} = \frac{12}{ - 6} \\ x = - 2[/tex]

Answer:

Cylinder B

Step-by-step explanation:

V = [tex]\pi r^{2} h[/tex]

Cylinder A : π × 3² × 5 = 141.37

Cylinder B: π × 5² × 3 =235.62

Answer:

Step-by-step explanation:

length (l) = 3 ft

Width (w) = 3 ft

Height (w) = 6 ft

Surface area = 2*( lw  + wh + hl)

                    = 2* (3*3 + 3*6 + 6*3)

                    = 2*(9 + 18 + 18)

                   = 2 *  45

                   = 90 square ft
