Answer:

=2x-4

Step-by-step explanation:

Answer:

The fully simplified form is2x-4

Step-by-step explanation:

Use Distributive property

5(x-2)=5x-10

3(2-x)=6-3x

5x-10+6-3x

Combine like terms

2x-4

[tex] \frac{6}{3} = \frac{y}{9} [/tex]

Given parameters:

Diameter of the malt balls  = 0.8in

Dimensions of the prism = 4in x 3in x 7.5in

Unknown:

Number of malt balls that will fit in the carton = ?

Solution:

To solve this problem, we need to find the volume of each of the malt balls, and then the volume of the rectangular prism.

Volume of the malt balls  = [tex]\frac{4}{3} \pi r^{3}[/tex]

This is because we assume that the balls have a spherical shape.

    Where r is radius and π is a constant

Radius of the malt balls  = [tex]\frac{0.8}{2}[/tex]   = 0.4in

So, volume  = [tex]\frac{4}{3} x 3.142 x 0.4^{3}[/tex]   = 0.27in³

Volume of the rectangular prism = l x w x h

  where l is the length

            w is the width

            h is the height

So the volume is 4 x 3 x 7.5 = 90in³

The number of malt balls that can be packed here = [tex]\frac{90}{0.27}[/tex]   = 333 malt balls

Answer:

3484 [tex]ft^{2}[/tex]

Step-by-step explanation:

a = bh

a = 67 x 52

a = 3484

Answer:

=> B.) 3,484 ft2

Step-by-step explanation:

=> The area of parallogram = base × height square units..

=> 67ft × 52ft

=> 3,484 ft²

Answer:

Step-by-step explanation:

to get the area of the given figure,

we need to split it in to two (see attached)

then area of a rectangle = length x width

A1 = 15 cm x 4 cm = 60 cm²

A2 = 5 cm x 4 cm = 20 cm²

Area = A1 + A2

        = 60 + 20

        = 80 cm²

Area in this figure will be 80cm².

The area of the rectangle can be calculated by the product of length and breadth of the rectangle.

A=l*b

where l is length and b is the breadth.

So according to asked question in the drawn figure,

connect the point B and G.

now this figure will give two rectangle i.e. ABGH and CDEF

Rectangle ABGH has length l=5cm

breadth b=4cm

area of the rectangle ABGH= length * breadth=l*b=5*4=20cm²

Now CF=CB+BG+GF=5+5+5=15

Rectangle CDEF has length l=CF=15cm

breadth b=4cm

area of the rectangle ABGH= length * breadth=l*b=15*4=60cm²

Area of the figure= area of the rectangle ABGH+area of the rectangle CDEF

=20cm²+60cm²

=80cm²

Therefore area in this figure will be 80cm².

Answer:

Its answer B!

Step-by-step explanation:

Answer:

minute hand:

in 60 minutes, the minute hand travels 360 degrees

60mins : 360°

1    : 6

so in 1 minute, the minute hand travels 6°

hour hand:

in 12hours the hour hand moves 360 degrees

in one hour, it moves 30 degrees

60min  : 30°

6mins   : 3°

1min     : 3/6 = 0.5°

so in 1 minute, the hour hand travels 0.5°

Answer:297

Step-by-step explanation:

Answer:

[tex]m = \frac{4}{3} = 1.3334[/tex]

Step-by-step explanation:

To find the slope of a line, all you have to do is determine 2 points that pass through this line;

for example, in this case,

(-4,-2) (4,4)

Use the equation;

[tex]m = \frac{y2 - y1}{x2 - x1} = \frac{4 - ( - 4)}{4 - ( - 2)} = \frac{4 + 4}{4 + 2} [/tex]

[tex]m = \frac{8}{6} = \frac{4}{3} [/tex]

This line passes through the point (1,0) and that is your y-intercept.

[tex]y = \frac{4}{3} x + 1[/tex]

The requried slope of the given line is m = 3/4.

The slope of the line is defined as the ratio of the rise and run of the straight line on the curve is given as;

m = (y₂ - y₁) / (x₂ - x₁)

Here,
From the graph, we have (-4, -2) and (4, 4).

The slope of the line is given as:

m = (y₂ - y₁) / (x₂ - x₁)

m = (4+2)/(4+4)
m = 6/8
m = 3/4

Thus, the requried slope of the given line is m = 3/4.

Answer:

1, 4, 5, 8 equals to 135 ( you can get these answers by simply calculating: 180 - 45 = 135 ( which are angles in a straight line[8 & 5].) 4 = 135 (corresponding angle to 8) and you get 1 = 135 ( opposite angle of 4)

2, 3, 6 equals to 45 ( you can get these answers from observing. 6 is opposite 45 therefore it is = 45°. 2 = 45( corresponding angle). 3 = 45 (opposite angles of 2 and is also alternate to 6)

Answer:

180

Step-by-step explanation:

m(< 1) + m (< 2) + m (< 3) = 180

Hi!

Your answer is "Multiplicative Inverse Property".

We can see that it's multiplying both sides by [tex]\cfrac{5}{4}[/tex] to get [tex]x[/tex] by itself.

This is known as the "multiplicative inverse" because the numerator and the denominator are swapped.

When a number is multiplied by its multiplicative inverse, it equals 1.

Answer:

D) Graph Z

Step-by-step explanation:

Convert from point-slope to slope-intercept form

[tex]y-6=4(x-4)\\\\y-6=4x-16\\\\y=4x-10[/tex]

This tells us that the line intersects the y-axis at (0,-10) and that our slope is 4. Therefore, the best choice given the options is D, graph Z.

The linear equation y = 4x - 10 represents the graph z. Then the correct option is D.

A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.

The linear equation is given as,

y = mx + c

Where m is the slope of the line and c is the y-intercept of the line.

The linear equation is given below.

y - 6 = 4(x - 4)

Convert the equation into slope-intercept form. Then we have

y - 6 = 4(x - 4)

y - 6 = 4x - 16

y = 4x - 16 + 6

y = 4x - 10

The slope of the line is 4 and the y-intercept of the line is negative 10. Then the equation represents the graph z, then option D is correct.
