Complete question :

Ray starts walking to school at a rate of 2 mi/h. Ten minutes later, his sister runs after him with his lunch, averaging 6mi/h. Determine take it takes for sister to catch up

Answer:

5 minutes

Step-by-step explanation:

Ray's rate = 2mi/ hr

Time walked before sister starts = 10 minutes = (10/60) = 0.16667 hours

Hence, distance already covered = (rate * time) = (2 * 0.16667) = 0.3333 miles

To catchup :

Let t = Time taken to catch ; At t, distance covered must be the same ; thus ;

0.3333 + (2 * t) = 6 * t

0.3333 + 2t = 6t

0.3333 = 6t - 2t

0.3333 = 4t

t = 0.3333 / 4

t = 0.0833333 hours

t = 0.0833333 * 60 = 5 minutes

Step-by-step explanation:

5. Since rectangle JKLM has two equal diagonals that intersect each other, therefore JN = MN.

If JN = MN therefore:

m<NMJ = m<NJM

Thus:

3x + 38 = 7x - 2

Solve for x. Collect like terms

3x - 7x = -38 - 2

-4x = - 40

Divide both sides by -4

x = 10

✔️Find m<NMJ

m<NMJ = 7x - 2

Plug in the value of x

m<NMJ = 7(10) - 2 = 70 - 2

m<NMJ = 68°

✔️Find m<NML;

m<NML = 90 - 68° (Complimentary angles)

m<NML = 22°

6. Diagonal of a rhombus bisects teach vertex angle, this means that <U is divided into two equal parts. Therefore:

10x - 23 = 3x + 19

Solve for x. Collect like terms

10x - 3x = 23 + 19

7x = 42

Divide both sides by 7

x = 6

✔️Find m<RST:

m<SUT = m<RST (opposite angles of a rhombus are congruent)

Thus,

m<SUT = (10x - 23) + (3x + 19)

Plug in the value of x

m<SUT = (10(6) - 23) + (3(6) + 19)

= (60 - 23) + (18 + 19)

= 37 + 37

m<SUT = 74°

Also, m<RST = 74°

Answer:

10

Step-by-step explanation:

The solutions for the equation (x - 3)² = 49 are x = 10 and x = -4.

To solve the equation (x - 3)² = 49, we can take the square root of both sides of the equation to eliminate the squared term.

√[(x - 3)²] = √49

Taking the square root of a square cancels out the exponent, resulting in:

|x - 3| = 7

Now, we have two cases to consider:

x - 3 = 7

In this case, we add 3 to both sides:

x = 7 + 3

x = 10

-(x - 3) = 7

Here, we distribute the negative sign:

-x + 3 = 7

Then, subtract 3 from both sides:

-x = 7 - 3

-x = 4

To isolate x, multiply both sides by -1, remembering to flip the inequality:

x = -4

Therefore, the solutions for the equation (x - 3)² = 49 are x = 10 and x = -4.

Answer:

2 stickers will be left over

Step-by-step explanation:

To answer the question, all you need to do is figure out at what value of stickers would the remaining stickers be equal to 2 if the piles are made up of either 3 to a set or 4 to a set. To do this, we need to figure out the size of the whole set of stickers.

Lets assume that the total number of stickers is 14. Lets test the 2 given conditions. If we divide it in piles of 3 then we will have a pile of 12 stickers (4 piles of 3 stickers each) with 2 stickers remaining.

Lets test the second condition. If we divide it in piles of 4, we will again have 12 stickers (3 piles of 4 stickers each) with 2 stickers remaining.

Now that both conditions have been satisfied, all we have to do is see how many stickers are left if we make a pile of 12 stickers. In this case, we will have just one pile of 12 stickers and, again, we will be left with 2 stickers.

Therefore, the answer is 2 stickers

Answer:

If Norma performed 178 haircuts in a month, she would pay $534 to either salon

Step-by-step explanation:

Saloon 1:

Cost of saloon 1 = $534

Saloon 2:

Cost of saloon 2 = 3h

Where,

h = number of haircut

Equate the cost of renting either saloon

534 = 3h

h = 534 / 3

h = 178 hair cut

If Norma performed 178 haircuts in a month, she would pay $534 to either salon.

Answer:

The mistake he made was not distributing the 1/4 to all the terms in the parentheses. It should've instead become 1/4x + 3, which would then lead to a different answer

Answer:

He forgot to divide 12 by 4.

Step-by-step explanation:

1/4(x + 12) = 2

1/4(x) + 1/4(12) = 2

x/4 + 12/4 = 2

x/4 + 3 = 2

x/4 = -1

x = -1/4

The slope is –2

Step-by-step explanation:

Slope is Rise/Run

The change in y-values is the Rise. The line goes down from left to right here, so it is negative.

The Run is the change in x-values.

Here, for every 2 units of change in x, the y changes by 4, negative.
