Hello!

If we have two fractions that are being added or subtracted with the same denominator, we can simply add up the numerators and keep it over the same denominator.

Let's use this question as an example:

Suppose Jonathan eats 6 packages of pemmican. He also eats some biscuits. Create an equation that models the total number of calories Jonathan consumes, y, based on the number of biscuits he eats, x, and the 6 packages of pemmican.​

Answers

Using proportions, it is found that the equation that models the total number of calories Jonathan consumes is given by:

y = 810 + 75x.

What is a proportion?

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

In this problem:

Each biscuit has 75 calories, hence x biscuits will have 75x calories.Each package of pemmican has 135 calories, hence 6 packages will have 6 x 135 = 810 calories.

Thus, the equation is given by:

y = 810 + 75x.

the x-axis to create Q'P'R', find the coordinates of R.
A. (-7,0)
B. (3,0)
C. (5,-6)
D. (7,0)

Answers

Answer:

D. (7, 0)

Step-by-step explanation:

The rule for a reflection over the y-axis is (x, y) → (x, -y)

This means that the x-values stay the same while the y-values change.

Q(x, y) → (x, -y)

Q(3, 0) → (3, 0)

Q'(3, 0)

P(x, y) → (x, -y)

P(5, 6) → (5, -6)

P'(5, -6)

R(x, y) → (x, -y)

R(7, 0) → (7, 0)

R'(7, 0)

Therefore, the correct answer is D.

Angle B is 180-107=73

Angle 1 is equivalent to B and it is 73

Answer:

C.  ∠1 = 73°

Step-by-step explanation:

Angles on a straight line add up to 180°

Therefore:

⇒ ∠1 + 107° = 180°

Subtract 107° from both sides:

⇒ ∠1 + 107° - 107° = 180° - 107°

sin ∅ = opposite / hypotenusecos ∅ = adjacent / hypotenusetan ∅ = opposite / adjacent

Therefore,

Sin D = opposite / hypotenuse = 12 / 15 = 4 / 5

sin E = opposite / hypotenuse = 9  / 15 = 3 / 5

cos D = adjacent / hypotenuse = 9 / 15 = 3  / 5

kono divides the numerator and denominator of 48 over 72 by the greatest common factor to simplify the fraction in one step. by what number does he divide?

Answers

Answer:

[tex]\sf Given\:fraction:\dfrac{48}{72}[/tex]

Factors of 48: 1, 2, 3, 4, 6, 8, 12, 16, 24, 48

Factors of 72:  1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72

So the greatest common factor (GCF) of 48 and 72 is 24.

Answers

Considering the hypotheses tested, it is found that the p-value for Nicolas's test is of 0.101.

What are the hypotheses tested?

At the null hypotheses, it is tested if the mean is of 24, that is:

[tex]H_0: \mu = 24[/tex]

At the alternative hypotheses, it is tested if it is different, hence:

[tex]H_1: \mu \neq 24[/tex]

As we are testing if the mean is different of a value, we have a two-tailed test, with t = -1.79 and 12 - 1 = 11 df. Hence, using a t-distribution calculator, the p-value is of 0.101.

A boy leaves home at 7:30 a.m and cycles to school, 6 km away, arriving at 7:45 a.m. The average speed of the boy as he cycles, in kmh, is (A) 32 (B) 24 (C) 18 (D) 16​

Answers

Answer:

B) 24

Step-by-step explanation:

distance = 6 km

we want the speed in km/h, so let's turn everything into either km or h if possible

time = 7:45 am - 7: 30 am = 15 minutes

60 minutes = 1 hour

1 hour / 60 minutes = 1

15 minutes * 1 = 15 minutes * 1 hour/60 minutes = 15 / 60 hours = 1/4 hours = 0.25 hours

note that we multiply by 1 hour / 60 minutes, not 60 minutes/ 1 hour. this is because we want the minutes to cross out -- because the original is given in minutes ( 15 minutes = 15 minutes/1) and is in the numerator, we need minutes in the denominator of 1 hour/60 minutes to cross it out

km = 6

h = 0.25

km/h = 6/0.25 = 24

Determine the coordinate of the point where
y=x−6 crosses the x-axis.

Answers

Answer:

(6, 0 )

Step-by-step explanation:

to find where the line crosses the x- axis, let y = 0 in the equation and solve for x

0 = x - 6 ( add 6 to both sides )

6 = x

the line crosses the x- axis at (6, 0 )

Given ↓The equation y=x-6

To find ↓The coordinate of the point where the equation crosses the x-axis

Calculations ↓Let y be 0

Instead of y write 0:

0=x-6

Now solve for x :

0=x-6

Add 6 on both sides

6=x or x=6

We know the x coordinate of the point that intersects the x axis; the y coordinate is always 0.

In how many ways can 8 people be seated in a row of chairs if three of the people, John, Wilma, and Paul, refuse to sit in three consecutive seats?

Answers

Answer:

I think it's easiest to count the ways that they can consecutively sit together and subtract this from the total number of seating arrangements.

There are 6 groups of 3 consecutive seats.  Within each group there are 3!=6 ways the three people can be arranged

Then the remaining 5 people can be arranged 5!=120 ways in the remaining seats.

So there are 6*6*120 = 4320 arrangements where they DO sit consecutively

There are 8! = 40320 total arrangements.

So there are 40320 - 4320 = 36000 arrangements where the 3 do not sit consecutively.

Answers

The incorrect claim is A. He is incorrect. The path will have an area of (4)(40)=160 sq ft. The yard has an area of 600 sq ft. The area of the lawn will be the difference of the yard and path, so it is 440 sq ft.
