Rachel bought a meal at the restaurant and gave an 18% tip. If the tip was $6.30 and there
was no sales tax, how much did her meal cost?

Answer:

The slope of a line is a measure of its steepness. Mathematically, slope is calculated as "rise over run" (change in y divided by change in x).

Step-by-step explanation:

[tex]\implies {\blue {\boxed {\boxed {\purple {\sf {Numerator\:=\:25 }}}}}}[/tex]

[tex]\large\mathfrak{{\pmb{\underline{\red{Step-by-step\:explanation}}{\red{:}}}}}[/tex]

[tex] \: \frac{ - 3}{7} + \frac{7}{8} [/tex]

Since the denominators are unequal, we find the L.C.M (lowest common multiple) for both denominators.

The L. C. M for 7 and 8 is 56.

Now,

➺[tex] \: \frac{ - 3 \times 8}{7 \times 8} + \frac{7 \times 7}{8 \times 7} [/tex]

➺[tex] \: \frac{ - 24}{56} + \frac{49}{56} [/tex]

Now that the denominators are equal, we can add them.

➺[tex] \: \frac{ - 24 + 49}{56} [/tex]

➺[tex] \: \frac{ 25}{56} [/tex]

Therefore, the numerator is [tex]\boxed{ 25 }[/tex] and the denominator is [tex]\boxed{ 56 }[/tex].

Answer:

Mean = 5.08

Step-by-step explanation:

The mean is the average of the numbers. It is easy to calculate: add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.

[tex] \frac{2.3 + 0.3 + 7 + 6.1 + 9.7}{5} [/tex]

[tex] = \frac{25.4}{5} [/tex]

= 5.08

5 rows are to be added in the pattern if the ratio will be 7:6 between number of straight lines.

A pattern is a sequence. It can be an AP, GP also.

present ratio between number of straight lines and number of arcs

=8:9

When we add 1 row it will increase 4 straight lines and 3 arcs. So when 5 rows are added it will increase 20 straight lines and 15 arcs.

Then total number of straight lines will be 28 and the total number of arcs will be 24 and the ratio will be 28:24 which after dividing by 4 becomes 7:6.

Hence 5 rows are to be added in the pattern B to get the ratio 7:6.

Answer:

k - 2 = 4d - 8

d + 1 = 4d - 8

Step-by-step explanation:

Daniel's age = d

Kevin's age = k

Given that, k = d + 3 -------------- (1)

Two years ago, the age of Daniel = d - 2

Two years ago, the age of Kevin = k - 2

Since,  two years ago, Kevin was 4 times as old as

Daniel, k - 2 = 4(d - 2)

Opening the bracket,

k - 2 = 4d - 8

Since the value of k is d + 3 (see (1))

d + 3 - 2 = 4d - 8

d + 1 = 4d - 8

(I am just giving the answer cause I LOVE Linear Equation )

1 + 8 = 4d - d

9 = 3d

9/3 = d

3 = d

Therefore, Daniel's present age is 3 and Kevin's present age = 6

Work Shown:

The cylinder has volume of...

V = pi*r^2*h

V = 3.14*4^2*8

V = 401.92

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

The rectangular prism has a volume of...

V = L*W*H

V = 10*7*6

V = 420

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

Subtract the two results:

420-401.92 = 18.08

The cylinder has roughly 18.08 more cubic units of volume compared to the rectangular prism.

Answer:

volume of cylinder: V=Sđ*h=R^2*3.14*8

volume of rectangular prism: V=Sđ*h=10*7*6

Answer:

x=2

Step-by-step explanation:

the minimum value of y is when x = 2.

Answer:

The minimum is at x = -2

Step-by-step explanation:

f(x) = (x+2)^2 -3

This is in vertex form

f(x) = ( x-h)^2 +k  where (h,k) is the vertex

Since this is an  upwards  opening  parabola the vertex is the minimum

f(x) = (x- -2)^2 -3

The vertex is (-2,-3)

The minimum is at x = -2

Answer:

1773.91 miles

Step-by-step explanation:

Given data

Completed miles= 816 miles

Percentage completion= 46%

Let the total distance be x

Hence

46% of x= 816

let us find x

46/100*x= 816

0.46x=816

x= 816/0.46

x= 1773.91

Therefore the total distance is 1773.91 miles

Since segment AC bisects (aka cuts in half) angle A, this means the two angles CAB and CAD are the same measure. I'll refer to this later as "fact 1".

Triangles ABC and ADC have the shared segment AC between them. By the reflexive property AC = AC. Any segment is equal in length to itself. I'll call this "fact 2" later on.

Similar to fact 1, we have angle ACB = angle ACD. This is because AC bisects angle BCD into two smaller equal halves. I'll call this fact 3

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

To summarize so far, we have these three facts

in this exact order, we can use the ASA (angle side angle) congruence property to prove the two triangles are congruent. Facts 1 and 3 refer to the "A" parts of "ASA", while fact 2 refers to the "S" of "ASA". The order matters. Notice how the side is between the angles in question.

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

Once we prove the triangles are congruent, we use CPCTC (corresponding parts of congruent triangles are congruent) to conclude that AB = AD and BC = BD. These pair of sides correspond, so they must be congruent in order for the entire triangles to be congruent overall.

It's like saying you had 2 identical houses, so the front doors must be the same. The houses are the triangles (the larger structure) and the door is an analogy to the sides (which are pieces of the larger structure).

Answer:

y=8x-26

y=-1/8x-13/8

Step-by-step explanation:

Y=kx+b

When the two lines are parallel,

k1=k2

k2=8 And passes through the point (3, -2)

So y+2=8(x-3)

Get the answer y=8x-26

When the two lines are perpendicular,

k1*k2=-1

K2=-1/8 And passes through the point (3,-2)

So y+2=-1/8（x-3）

Get the answer y=-1/8x-13/8
