Answer:

x = 34.8

Step-by-step explanation:

adjacent/hypotenuse = cos(x)

cos(x) = 2.3/2.8

x = [tex]cos^{-1} [/tex](2.3/2.8)

x =  34.77

x = 34.8 ____if rounded to nearest tenth

The sheet required to cover the rhombus is: 300 sq. cm.

Thus:

a = 40 cm

b = 15 cm

Sheet required to cover the rhombus = area of the rhombus.

Area = (40 × 15)/2

Area = 300 sq. cm.

Therefore, the sheet required to cover the rhombus is: 300 sq. cm.

Answer:

Step-by-step explanation:

y = 2x --------------(I)

5x + y = 7 ------------(II)

Substitute y = 2x in equation (II)

5x + 2x = 7

7x = 7

Divide both sides by 7

x = 7/7

x = 1

Plugin x = 1 in (II)

y = 2*1

y = 2

Answer:

$480

Step-by-step explanation:

First: divide 360/12 to find the cost of 1 mango.

The answer should be $30.

Then, multiply 30 by 16 to find the cost of all 16.

The final answer should be $480.

Answer:

$27,176

Step-by-step explanation:

Since the discount is 20%, you pay only 80% of the original price since the original price was 100% of the original price, and the discount is 20% of the original price (100% - 20% = 80%).

Now we find 80% of $33,970.

80% of $33,970 =

= 80/100 × $33,970

= 0.8 × $33,970

= $27,176

Answer:

( 4, -1/2)

Step-by-step explanation:

To find the x coordinate of the midpoint, add the x coordinates and divide by 2

( 1+7)/2 = 8/2 =4

To find the y coordinate of the midpoint, add the y coordinates and divide by 2

( -6+5)/2 = -1/2

( 4, -1/2)

Answer:

slope = - [tex]\frac{1}{2}[/tex]

Step-by-step explanation:

Calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 4, 7 ) and (x₂, y₂ ) = (8, 1 )

m = [tex]\frac{1-7}{8-(-4)}[/tex] = [tex]\frac{-6}{8+4}[/tex] = [tex]\frac{-6}{12}[/tex] = - [tex]\frac{1}{2}[/tex]

Step-by-step explanation:

Let's say L for 'Large pizza' and S for 'Small pizza'.

We know that:

Work:

        3S + 4L = 23

Now, let's substitute the value of L into the first equation.

Hence, each large pizza feeds about 5 people and each small pizza feeds about 1 person.

Answer:

y = -1/3x + 2

Answer:

Step-by-step explanation:

l// m , t is transversal.

Corresponding angles are equal.

3x - 20 = 2x + 10

Add 20  to both sides

3x  = 2x + 10 + 20

3x = 2x + 30

Subtract 2x from both sides

3x - 2x = 30

x = 30

Answer:

y = 3x + 12

Step-by-step explanation:

I'm not sure what variable they use, but you can substitute any in for y and x.

For example, it can also be c = 3h + 12

The word per links the amount to the variable. You have to pay the $12 no matter what so that is why it doesn't have the variable and is the constant.

Step-by-step explanation:

Hi there!

The given points are: A(5,8) and B (-3,4).

Formula: [tex]\sqrt{(x2-x1)^{2}+(y2-y1)^{2} }[/tex]

Insert the values;

Distance (d) = [tex]\sqrt{(-3-5)^{2}+ (4-8)^{2} }[/tex]

                d = [tex]\sqrt{(-8)^{2}+(-4)^{2} }[/tex]

                 d = [tex]\sqrt{64+16}[/tex]

Answer:

4.8 miles

Step-by-step explanation:

You can use a proportion.

6/55 = x/44

55x = 6 × 44

55x = 264

x = 264/55

x = 4.8

Answer: 4.8 miles

44 / 55 = 4 / 5

4 / 5 = 0.8

0.8 * 6 = 4.8 miles

keeping in mind that parallel lines have exactly the same slope, let's check for the slope of the equation above

[tex]2x+y-3=0\implies y=\stackrel{\stackrel{m}{\downarrow }}{-2} x+3 \impliedby \begin{array}{|c|ll} \cline{1-1} slope-intercept~form\\ \cline{1-1} \\ y=\underset{y-intercept}{\stackrel{slope\qquad }{\stackrel{\downarrow }{m}x+\underset{\uparrow }{b}}} \\\\ \cline{1-1} \end{array}[/tex]

so we're really looking for the equation of a line with a slope of -2 and that passes through (1 , -1)

[tex](\stackrel{x_1}{1}~,~\stackrel{y_1}{-1})\qquad \qquad \stackrel{slope}{m}\implies -2 \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{(-1)}=\stackrel{m}{-2}(x-\stackrel{x_1}{1}) \\\\\\ y+1=-2x+2\implies y=-2x+1[/tex]
