The number of miles planned on Saturday is 19 milea

This means the sequence where the difference between one term and the next term is a constant.

In this case, the following information are illustrated:

Sunday: 1 miles

Monday: 4 miles

Tuesday: 7 miles

Wednesday : 10 miles

Thursday: 13 miles

Friday: 16 miles

As we can see there's a difference of three between them. This can be seen as:

= 4 miles - 1 mile

= 3 miles

Therefore, the number planned on Saturday will be:

= Friday + 3 miles

= 16 miles + 3 miles

= 19 miles

Answer:

[tex]\boxed{\dfrac{1}{2} = m}[/tex]

Step-by-step explanation:

Given equation:

[tex]\dfrac{3}{4} = m + \dfrac{1}{4}[/tex]

Step-1: Subtract 1/4 both sides

[tex]\dfrac{3}{4} = m + \dfrac{1}{4}[/tex]

[tex]\dfrac{3}{4} - \dfrac{1}{4} = m[/tex]

[tex]\dfrac{2}{4} = \boxed{\dfrac{1}{2} = m}[/tex]

Answer:

5^(3)i^(9)= five cubes times i to the power of 9=125i

Step-by-step explanation:

Raise 5 to the power of 3

rewrite i9 as (i^4)2^i

so, you get 125((i^4)^2i)

i^4=1

125(1^2i)

Answer:

  8/9

Step-by-step explanation:

A fraction that has denominator factors of 2 or 5 (only) will be finite in length. It will not be a repeating decimal fraction. This eliminates choices B and D.

The number of 9s in the denominator of a repeating decimal fraction will be equal to the number of repeating digits. The fraction 0.8888... has one repeating digit (8), so it can be written as 8/9.

_____

Additional comment

The fraction 80/99 will be the 2-digit repeating decimal 0.808080...

The fraction 1111/1250 evaluates to 0.8888, a 4-digit decimal fraction that does not repeat.

__

A fraction such as 0.142857...(6-digit repeat) can be written as ...

  124857/999999 . . . . denominator has 6 nines

This fraction reduces to 1/7.

Answer:

A = 44.42°

Step-by-step explanation:

SohCohToa

Soh = sin(theta)= opp/hyp

Coh = cos(theta)= adj/hyp

Toa = tan(theta)= opp/adj

Coh = cos(theta)= adj/hyp

cos(A)= adj/hyp

cos(A)= 5/7

A = cos^-1(5/7)

A ≈ 44.4153086

A = 44.42°

Answer:

∠KPL = 80°

Step-by-step explanation:

As KM is perpendicular to KP, this means that KM is the diameter of the circle, as the tangent of a circle is always perpendicular to the radius.

The angle at the circumference in a semicircle is always a right angle.  So if KM is the diameter then ΔKLM is a right triangle with ∠KLM = 90°

The sum of the interior angles of a triangle is 180°.

Therefore, ∠KLM + ∠KML + ∠LKM = 180°

As ∠KLM = 90° and ∠KML = 50°

⇒ 90° + 50° + ∠LKM = 180°

⇒ ∠LKM = 40°

As ∠PKM = 90° then

⇒ ∠PKL = 90 - ∠LKM

              = 90 - 40

              = 50°

Tangents from a common point to a circle are always equal in length, so as PK and PL are tangents from point P, then PK = PL

Therefore, ΔLPK is an isoceles triangle and so its base angles ∠PKL and ∠PLK will be equal.

Since ∠PKL = 50° then ∠PLK = 50°

Again, as the sum of interior angles of a triangle is 180°:

⇒ ∠KPL + ∠PKL + ∠PLK = 180°

⇒ ∠KPL + 50° + 50° = 180°

⇒ ∠KPL = 80°

Answer:

25 x D = Y

Step-by-step explanation:

Example: Say he reads for three days a week.

25 x 3 = 75

or 6 days

25 x 6 = 150

or 4

25 x 4 = 100

Answer:

No solution

Step-by-step explanation:

(I am going to use substitution)

2x−10y=−2

y=x/5−1

(Substitute the y into the other problem)

2x - 10 (x/5 -1) = -2

2x - 2x + 10 = -2

10 = -2

No solution

Hope this helps :)

A percentage is a proportion of some whole number. There are 2 ways to find percentages. Firstly, you can multiply by a decimal, or you can use a shortcut.

Multiplying with Decimals

You can always rewrite percentages as decimals. To do this move the decimal point 2 digits to the left. This means that 90% becomes 0.90. Then multiply this decimal by the whole number to find the correct percentage.

Shortcut

Because 90% is a multiple of 10%, we can use a shortcut. First off, find 10% of 140. To find 10% of any number, move the decimal 1 digit to the left. This means 10% of 140 is 14.0. Next, 90% is 10% less than 100%. So, subtract 10% from 140 to find 90%.

Answer:

126

Step-by-step explanation:

We need to find 90% of 140.

90% is the same as 0.9 or 9/10.

140 can be written as 14 x 10.

Multiply 14 x 10 with 9/10.

⇒ 14 x 10 x 9/10

[The 10 and 1/10 cancel out by cross multiplication]

⇒ 14 x 9

⇒ 126

[tex]\left(\because \log _{c}(a \cdot b)=\log _{c} a+\log _{c} b\right)[/tex]

[tex]=\log _{3} 2+\log _{3} x+3 \log _{3} y+5 \log _{3}z \rightarrow \left(\because \log _{c} a^{b}=b \log _{c} a\right)[/tex]

Step-by-step explanation:

If 4 hamburger = $21.25

1 hamburger = x

Cross multiply

4 x x = $21.25 x 1

4x = $21.25

Devide both side with the coefficient of x

4x/4 = $21.25/4

X = $5.3125

Therefore 1 hamburger cost $5.31

If 4 hotdogs = $22.75

1 hotdog = y

Cross multiply

4 x y = $22.75 x 1

4y = $22.75

Devide both sides with the coefficient of y

4y/4 = $22.75/4

Y = $5.6875

Therefore one hotdog cost $5.69

Answer:

I think the answer is: y = 0.5x^2 + 4x + 6, <3

Step-by-step explanation:

Answer:

x = 10

y = 15

Step-by-step explanation:

5x − 4y = −10  ⇒  ( 1 )

y = 2x − 5     ⇒ ( 2 )

Let us find the value of x.

For that, we can replace y with ( 2x - 5 ).

Let us take equation 1.

5x − 4y = −10

5x - 4 (  2x − 5 ) = -10

5x - 8x + 20 = -10

-3x = -20 - 10

-3x = - 30

Divide both sides by ( -3 ).

x = 10

And now let us find the value of y.

Let us take equation 2.

y = 2x − 5

y = 2 × 10 - 5

y = 20 - 5

y = 15

Answer:

X=10

Step-by-step explanation:

5x-4y=-10.....1

y=2x-5......2

sub 2 into 1

5x-4(2x-5)=-10

5x-8x+20=-10

5x-8x=-10-20

-3x=-30

x=10

sub x=10 into 2

y=2(10)-5

y=20-5

y=15

Answer:

$316.8

Step-by-step explanation:

9 x 44 = 396

396 × 0.80 = $316.8

or

396 * 0.20 = 79.2

396 - 79.2 = $316.8

Answer:

Step-by-step explanation:

Since the prices increase at a monthly rate of 0.1% per month. To find the percentage do they increase a year, we need to convert 0.1% to a decimal.

So here how we do it. We put 0.1 percent on the numerator because it a small number which is what we want over 100 like this:

[tex]\frac{0.1}{100}[/tex]

Now when plugging this into your calculator you get:

0.001

.So what do we do with this number?

We now times it by 12 like this:

0.001 x 12 which gives us:

0.012

So we can convert this back to a percentage by moving the decimal by 2 places to the right which gives us 1.2%.

Another way we could of done this without doing the long way to figure it out is by multiplying 0.1 times 12 which still gives us 1.2%
