Step-by-step explanation:

X2-12x+36 = 90.

X=

O x=6+3./10

O x=6+2/7

X= 123.22

O

x= 12+3/10

Answer:

x = 7[tex]\sqrt{3}[/tex]

Triangle area formula: base * height * 1/2

We are given:

Base - 14 cm

Height - x

Using the pythagorean theroem (a^2 + b^2 = c^2) we can figure out the height.

We are given:

Side a - 14 / 2 = 7 cm

Side b - the height (x)

Side c - 14 (it's an equilateral triangle)

Now, substitute the given values:

7^2 + x^2 = 14^2

49 + x^2 = 196

x^2 = 147

x = [tex]\sqrt{147}[/tex]

x = 7[tex]\sqrt{3}[/tex]

Answer:

a pair of glasses costs $17

a hat costs $21

Step-by-step explanation:

h = hat

g = glasses

3h + 4g = 123

1h + 3g = 66

multiply the 2nd equation by 3

3h + 9g = 198

negate everything in the 1st equation and add it to the 'new' 2nd equation

    3h  + 9g = 198

+  -3h  - 4g = -123

5g = 75

g = 15

substitute the 15 in either one of the 1st equations

1h + 3(15) = 66

h + 45 = 66

h = 66-45

h = 21

to check, substitute both g=15 and h=21 into BOTH 2 original equations.

Answer:

∠H = 137°

∠K = 76°

Step-by-step explanation:

The sum of the interior angles of a trapezoid = 360°

In a trapezoid, the angles on the same leg (called adjacent angles) are supplementary, meaning they add up to 180°

The legs are the non-parallel sides:  JK and HI

Therefore, 104 + ∠K = 180

⇒ ∠K = 180 - 104 = 76°

And, ∠H + 43 = 180

⇒ ∠H = 180 - 43 = 137°

Sum of two adjacent angles in trapezium equals 180°

[tex]\\ \tt\hookrightarrow <H+43=180[/tex]

[tex]\\ \tt\hookrightarrow <H=180-43[/tex]

[tex]\\ \tt\hookrightarrow <H=137[/tex]

And

[tex]\\ \tt\hookrightarrow <K+104=180[/tex]

[tex]\\ \tt\hookrightarrow <K=180-104[/tex]

[tex]\\ \tt\hookrightarrow <K=76°[/tex]

Step-by-step explanation:

Turn the equation into a slope-intercept form equation:

[tex]8y=3x+12[/tex]

Divide each side by 8 to simplify y:

[tex]y=\frac{3}{8} x+1.5[/tex]

The slope is 3/8.

Using the format:

[tex]y=mx+b[/tex]

3/8 is in place of m, the slope.

Answer:

I am assuming any number in between these two, so let's just say 6,550.

Step-by-step explanation:

If you count up from 6,534, you will eventually get to 6,550. If you continue to count up, you will eventually reach 6,565 which is bigger than 6,550.

Step-by-step explanation:

The angle of depression from you to your friend is 54.1°

Trigonometric ratio is used to show the relationship between the sides and angles of a right angled triangle.

Let θ represent the angle between me in air and my friend, hence:

tanθ = 326 / 450

θ = 35.9 degrees

The angle of depression = 90 - 35.9 = 54.1°

The angle of depression from you to your friend is 54.1°

Answer: (-4, -7)

Step-by-step explanation: To solve this system of equations, we can use the substitution method.

To solve a system by substitution, we first need to isolate one of our variables. The problem is none of our variables has a coefficient of 1 or -1. In this situation, we have to look at our next best option.

In our first equation, add 2x to both sides to get

2y = -6 + 2x and just divide both sides by 2 to get y = -3 + x.

Now let's plug this value of y into our second equation.

So we have 3x + 7(-3 + x) = -61.

Simplifying from here:

3x - 21 + 7x = -61

10x - 21 = -61

10x = -40

x = -4

Since we know that x = -4, we can just plug a -4 into our equation that we created earlier to get y = -3 + (-4) or y = -7.

Since x = -4 and y = -7, our answer is the ordered pair (-4, -7).

Step-by-step explanation:

from the question we see root 27 and root 64

so what we do next is we look for two numbers that we can multiply together to give 27 and 64 in which one if the number is a perfect square

for root 27 we use 9 and 3

for root 64 we use 16 and 4

Answer:

You would need 16 1/3 cups!

Step-by-step explanation:

I used an equation, but you could also use mental conversions! :

1/3c = 5 1/3

(1/3c)3 = (5 1/3)3 (multiply each side by 3 (3/1))

3c /3 = (48) /3 (divide each side by 3)

c = 16

:)

(c = cups!)

The requried number of 1/3 cups to make the recipe is 16.

The equation model is defined as the model of the given situation in the form of an equation using variables and constants.

here,
Measuring cup = 1/3
Recipe required number of cups = 5 1/3 of flour,
Let the number of 1/3 cups = x
1/3x = 5 1 / 3
x/3 = 16 / 3
x = 16

Thus, the requried number of 1/3 cups to make the recipe is 16.
