Answer:

B

Step-by-step explanation:

Since the relationship is linear then the slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

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

with (x₁, y₁ ) = (5, - 1) and (x₂, y₂ ) = (10, 1) ← 2 ordered pairs from the table

m = [tex]\frac{1+1}{10-5}[/tex] = [tex]\frac{2}{5}[/tex]

The point (0, - 3 ) indicates c = - 3 , then

y = [tex]\frac{2}{5}[/tex] x - 3 ( multiply through by 5 to clear the fraction )

5y = 2x - 15 ( subtract 2x from both sides )

5y - 2x = - 15 → B

Answer:

There are 8 nickels and 14 pennies

Step-by-step explanation:

Represent the number of pennies by p and nickels by n.  Then:

p + n = 22, or n = 22 - p

Coin values:

($0.01/penny); ($0.05/nickel).  Therefore, the relation showing the amounts of money involved is:

($0.01/penny)p + ($0.05/nickel)n = $0.54.

But we found earlier that n = 22 - p.  Therefore, the previous equation becomes:

($0.01/penny)p + ($0.05/nickel)(22 - p) = $0.54.

Multiply all three terms by 100 to eliminate the decimal fractions:

1p + 5(22 - p) = 54, or:

1p + 110 - 5p = 54, or:

-4p = -56

Thus, p = 14.  If p = 14, then n = 22 - 14 = 8.

There are 8 nickels and 14 pennies.

Check:  8($0.05) + 14($0.01) = $0.54 (correct)

To find an equation of a line, you have to know the value of slope first. We can find the value of slope by using the formula below:

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

m-term represents the slope from y = mx+b.

We are given two coordinate points. Substitute the points in the formula.

[tex] \large{m = \frac{7 - 5}{3 - 0} } \\ \large{m = \frac{2}{3} }[/tex]

Therefore the slope is 2/3.

Next we find the y-intercept. In the form of y = mx+b where m = slope and b = y-intercept. We have got slope, except the y-intercept. We can find the y-intercept by substituting one of gjven points in the equation of y = mx+b.

Since we know the slope - we can rewrite the equation like below:

[tex] \large{y = \frac{2}{3} x + b}[/tex]

Then choose one of two points to substitute. I will choose (0,5). Therefore substitute x = 0 and y = 5.

[tex] \large{5 = \frac{2}{3} (0) + b} \\ \large{5 = 0 + b} \\ \large{b = 5}[/tex]

Thus the y-intercept is (0,5). Note that if the question gives you (0,a) point. That is the y-intercept of graph. So b = a if given (0,a).

Rewrite the equation by substituting the b-value.

[tex] \large{y = \frac{2}{3} x + 5}[/tex]

Hence, the equation of a line that contains those points is y = 2x/3 + 5

Answer:

tom = 166, ben = 581

Step-by-step explanation:

2 + 7 = 9

747 ÷ 9 = 83

therefore 1 part = 83

83 x 2 = 166

83 x 7 = 581

tom has 2 parts so he has 166

ben has 7 parts so he has 581

Answer:

Tom has 166.

Ben has 581.

Step-by-step explanation:

2 + 7 = 9

747 ÷ 9 = 83

83 × 2 = 166

Given:

Diameter of ball = 8 cm

To find:

The volume of the ball.

Solution:

We know that the radius of sphere is half of is diameter.

It is given that the the diameter of ball is 8 cm. So, the radius of the ball is:

[tex]r=\dfrac{8}{2}[/tex]

[tex]r=4[/tex]

The radius of the ball is 4 cm.

The volume of a sphere is:

[tex]V=\dfrac{4}{3}\pi r^3[/tex]

Where r is the radius of the sphere.

Putting [tex]\pi = 3.14, r=4[/tex] in the above formula, we get

[tex]V=\dfrac{4}{3}(3.14)(4)^3[/tex]

[tex]V=\dfrac{4}{3}(3.14)(64)[/tex]

[tex]V=267.946667[/tex]

[tex]V\approx 267.95[/tex]

Therefore, the volume of the ball is about 267.95.

Answer:

Step-by-step explanation:

angle y +60  = 180 degree (being adjacent angles of a trapezium )

angle y =180 - 60

angle y =120 degree

angle x+30 degree = 180 degree (being opposite angles of a trapezium)

angle x =180 - 30

angle x=150 degree

75 + 145 + 90 + y = 360 degree (sum of angles of a quadilateral is 360 degree)

310 + y = 360

y = 360 - 310

y = 50 degree

========================================

Explanation:

Ignore lines BC and FE. It might help to redraw the figure without those lines present. Refer to the diagram below. Doing this is optional if you can spot what's going on without having to erase those lines.

Notice how angles 1 and 3 are congruent corresponding angles, due to lines FJ and DC being parallel.

Since angle 3 is 55 degrees,  angle 1 is also 55 degrees.

--------------

Once we determine angle 1, we subtract from 180 because angle ABF is supplementary to angle 1 (aka angle ABJ)

In other words,

(angle ABJ) + (angle ABF) = 180

angle ABF = 180 - (angle ABJ)

angle ABF = 180 - (angle 1)

angle ABF = 180 - (55)

angle ABF = 125 degrees

Answer:

x = -19/2      y = -33/2

Step-by-step explanation:

x - (3x + 12) = 7

x - 3x - 12 = 7

-2x - 12 = 7

-2x = 19

x = -19/2

x - y = 7

-19/2 - y = 7

-y = 33/2

y = -33/2

Answer:

35.00

Step-by-step explanation:

Sin(B)/b = Sin(A)/b

a* Sin(B) = b Sin(A)

b = a * Sin(B)/ Sin(A)

Plug in --> Get answer

The value of b is 34.75.

It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.

From the law of sin,

Sin 29.8/c = Sin 34.5/22 = Sin B/b

Now,

The sum of the angles in a triangle is 180.

So,

∠A + ∠B + ∠C = 180

34.5 + ∠B + 29.8 = 180

∠B = 180 - (34.5 + 29.8)

∠B = 115.7

Now,

Sin 34.5/22 = Sin B/b

0.57/22 = Sin 115.7/b

0.57/22 = 0.90/b

b = (0.90 x 22) / 0.57

b = 34.74

Thus,

The value of b is 34.75.

Answer:

  1.2 t/m³

Step-by-step explanation:

1 tonne is 1 Mg = 10⁶ g

1 m³ is (100 cm)³ = 10⁶ cm³

The conversion is ...

  (1.2 g/cm³) · (1 t)/(10⁶ g) · (10⁶ cm³)/(1 m³)

  = 1.2(10⁶)/(10⁶) t/m³

  = 1.2 t/m³

Answer:

(7/2, -9/2)

Step-by-step explanation:

to find the midpoint, we can use the midpoint formula, which is:

(x1+x2)/2, (y1+y1)/2

since we know the points (1,-1) and (6,-8) we can plug this into the formula:

for the x-coordinate: (1+6)/2=7/2 (or 3 1/2)

for the y-coordinate: (-1+(-8)/2=-9/2 (or -4 1/2)

so, the midpoint of the line segment would be (7/2, -9/2)
