What is Subtraction?

Subtraction is the process of taking away a number from another. It is a primary arithmetic operation that is denoted by a subtraction symbol (-) and is the method of calculating the difference between two numbers.

here, we have,

given that,

Drake’s monthly outlay include a $70 phone bill and a $120 car assuming he makes $400 a month,

i.e. we get,

Drake’s monthly outlay include a $70 phone bill and a $120 car.

so, total spend = $ 120 + 70

                         = $190

now, we have to find how much does he have to spend after paying his bills.

so, we have to subtract 190 from 400

i.e. 400 - 190

=210

Hence, $210 does he have to spend after paying his bills.

The volume of a cylinder is approximately 942 cubic inches. The height of the cylinder is 12 inches. Which is the best approximation for the radius of the cylinder? 4 inches, 6 inches, 7 inches, 5 inches

Answers

Answer: 5 inches

Step-by-step explanation:

The volume of a cylinder is equal to pi*radius^2*height.

We can replace the height with 12 inches and the volume with 942 cubic inches.

Therefore, 942 in^3 = pi*radius^2*12 inches

We can divide both sides by 12:

pi*radius^2 = 78.5 inches^2

We can divide both sides by pi:

Radius^2 = About 24.99 inches^2

We can square both sides:

Radius approximately equals 5 inches.

What is an equation of the line that passes through the points (-6,-4) and
(-4,0)?

Answers

Answer:

y = 2x + 8

Step-by-step explanation:

the equation of a line in slope-intercept form is.

y = mx+b

where m is the slope and b the y-intercept

to calculate m use the gradient formula

m = (y2−y1 ) / (x2−x1)

let (x1,y1)=(-6,-4) and (x2,y2)=(-4,0)

m = (0 - (-4)) / (-4 - (-6) = 2

y = 2x+b←is the partial equation

to find b substitute either of the 2 given points

into the partial equation

using (-6, -4) then

-4 = -12+b⇒b=8

y = 2x + 8←is the equation of line

Determine whether the sequence is arithmetic, geometric, or neither: 20,17,14,11

Answers

Answer: Arithmetic

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

Explanation:

Add -3 to each term to get the next term. This is the same as subtracting 3 from each term. In this case, the common difference is d = -3.

The first term is a = 20

---------

The nth term formula for the arithmetic sequence is

a(n) = a+d(n-1)

a(n) = 20+(-3)(n-1)

a(n) = 20-3n+3

a(n) = -3n+23

If we plug in n = 1, we would get a(n) = 20. Plug in n = 2 to get a(n) = 17. And so on. This helps confirm we have the correct nth term formula.

360=164+71+24+x

360=260+x

x=360-260

x=100

Answer:

Step-by-step explanation:

Since angles in quadrilateral (4-sided shape) add up to 360 degrees

therefore,

360 = 164 + 71 + 25 + x

360 = 260 + x

subtract 260 from both sides

360-260 = 260-260 + x

Work out the length QR.
Give your answer correct to 3 significant figures.

Total marks: 5

Answers

Answer:

The length of QR is 29.9 cm

Step-by-step explanation:

Let us revise the sine and cosine rules

In triangle ABC:

[tex]\frac{AB}{sin(C)}=\frac{BC}{sin(A)}=\frac{AC}{sin(B)}[/tex] ⇒ sine rule

(AC)² = (AB)² + (BC)² - 2(AB)(BC)cos(∠B) ⇒ cosine rule

Let us use these rules to solve the question

In Δ PQS

∵ [tex]\frac{PS}{sin(Q)}=\frac{QS}{sin(P)}[/tex]

∵ PS = 11.7 cm

∵ m∠P = 95°, m∠Q = 28°

→ Substitute them in the rule above

∴ [tex]\frac{11.7}{sin(28)}=\frac{QS}{sin(95)}[/tex]

→ By using cross multiplication

∴ QS × sin(28) = 11.7 × sin(95)

→ Divide both sides by sin(28) to find QS

QS = 24.82680292 cm

Now let us use the cosine rule to find QR

In Δ QSR

∵ (QR)² = (QS)² + (RS)² - 2(QS)(RS)cos(∠QSR)

∵ RS = 10.2 cm

∵ m∠QSR = 110°

→ Substitute these values in the rule above

∴ (QR)² = (24.82680292)² + (10.2)² - 2(24.82680292)(10.2)cos(110)

∴ (QR)² = 893.631984

→ Take √  for both sides

∴ QR = 29.89367799

→ Round it to 3 significant figures

QR = 29.9 cm

75% off of a brand name mp3 player that costs $199
OR an off-brand mp3 player for $44.99

Answers

Answer:

Off-brand mp3 for $44.99

Step-by-step explanation:

Given;

75% off of a brand name mp3 player that costs $199 or  an off-brand mp3 player for $44.99

Note;

off = discount = decrease

Solve;

Starting with brand name mp3

$199 x 75% = 149.25

199 - 149.25= 49.75

Now with off brand mp3

$44.99 x 75% = 33.7425

Round 33.7425 = 33.74

$44.99 - 33.74 = 11.25

49.75 > 11.25

Hence, we can see that off-brand mp3 player is a better deal.

Find the equation of the line shown

Answers

Answer:

y=x+1

Step-by-step explanation:

The slope of the equation is 1, you can try the rise over run method or picking 2 points and subtracting them for example 2,3 and 3,4

2,3-3-4=1,1. The y-intercept is 1 because that is the point where the line crosses the y axis.

Answer:

Slope intercept form:

y = mx + b

Where 'y' is the independent variable and 'x' is the dependent variable.

'm' represents the slope(rise/run), and 'b' represents the y-intercept(where the line meets the y-axis).

If we look at this graph, we can see the line meets the y-axis at 1. So 1, will be our y - intercept.

We can also see, that from the point 1, it rises 1 and goes over 1. So 1, will be our slope as well.

To double check this, we select two fixed points on this graph and subtract the y-coordinates from each other and divide the result of that by the x-coordinates subtracted from each other.

y2(second y-coordinate) - y1(first y-coordinate)

_____________________________________

x2(second x-coordinate) - x1(first x-coordinate)

We pick the two points to be, (1,2) and (2,3).

 3 - 2              1

______ = _______, which is equal to 1, so 1 is the slope.

 2 - 1               1

Now we insert these values into our slope intercept form equation:-

y = mx + b

y = 1x + 1 or y = x + 1.

Where 1 is the slope, and the y-intercept is 1.
