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
Which steps will translate f(x) = 3x to g(x) = 3x + 1 + 4? Shift f(x) = 3x one unit up and four units to the right. Shift f(x) = 3x one unit up and four units to the left. Shift f(x) = 3x one unit to the right and four units up. Shift f(x) = 3x one unit to the left and four units up.
Answers
Answer:
Shift f(x) = 3x one unit to the left and four units up
Step-by-step explanation:
We need to translate :
f(x) = 3x ⇒ g(x) = 3x + 1 + 4Here we need to use a bit of logic.
All of the options involve shifting the f(x) graph one unit and four units in various directions.To shift the graph up by one by horizontal action, we need to move one unit left so the new equation is 3x + 1To shift it up further by 4 vertically, we need to move four units upHence, our final function g(x) is given as :g(x) = 3x + 1 + 4Answer:
Shift f(x) = 3x one unit to the left and four units up

A classroom has 26 chairs and 16 computers. What is the ratio of computers to chairs?
Answers
**THE PERSON UNDER ME IS ALSO CORRECT, THIS IS JUST ANOTHER WAY TO APPROACH RATIOS**
Explanation: Ratio seldom compares two numbers by dividing them (this depends on the problem). We are given A 16 computers and B 26 chairs. Therefore we have the formula of A/B.For example 16/26
Solving: Divide A by B: 16/26= 0.615 or 0.6
Multiple: Multiple the quotient by 100 in order to get the percentages. 0.615 x 100 = 61.5% (if you rounded 0.61, the answer would be 60%; for this problem I didnt round hence, 61.5%)
Answer: 61.5 %

Find sin D, sin E, cos D, and cos E. Write each answer as a fraction in simplest form
Answers
The value of sin D, sin E , cos D , and cos E in simplest fraction form are as follows:
Sin D = 4 / 5
sin E = 3 / 5
cos D = 3 / 5
cos E = 4 / 5
Trigonometric ratios:The simplest trigonometric ratios expression are as follows:
sin ∅ = opposite / hypotenusecos ∅ = adjacent / hypotenusetan ∅ = opposite / adjacentTherefore,
Sin D = opposite / hypotenuse = 12 / 15 = 4 / 5
sin E = opposite / hypotenuse = 9 / 15 = 3 / 5
cos D = adjacent / hypotenuse = 9 / 15 = 3 / 5
cos E = adjacent / hypotenuse = 12 / 15 = 4 / 5

Step-by-step explanation:
Sin= opposite/ hypotnuse
Con= addjacent/ hypotnuse
if you cant tell which side the hypotnues if on, it is always opposite from the 90 degree mark.
Now that you know how to make the fraction for Sin and Con, you would have to use a graphing calulator, plug in Sin^-1 or Con^-1 what ever the sign is and put the fractions in ( ) next to it and it will give you the decmle. Also using a graphing calculator is 100% allowed in this type of math.

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.

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 )
Instead of y write 0:
0=x-6
Now solve for x :0=x-6
Add 6 on both sides6=x or x=6
We know the x coordinate of the point that intersects the x axis; the y coordinate is always 0.
Coordinates of the point ↓(6, 0)
Roy wants to make a path from one corner of his yard to the other as shown below. the path will be 4 feet wide. he wants to find the area of lawn that remains. a rectangle has a height of 40 feet and a base of 15 feet. a 4 feet wide path forms a parallelogram inside of the rectangle. roy claims that the area of the lawn is 300 square feet since it covers exactly one-half of the yard. which statement about his claim is correct? 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. he is incorrect. the path will have an area of one-half (4) (40) = 80 sq ft. the yard has an area of 300 sq ft. the area of the lawn will be the difference of the yard and path, so it is 220 sq ft. he is incorrect. the path will have an area of (4) (40) = 160 sq ft. the yard has an area of 300 sq ft. the area of the lawn will be the difference of the yard and path, so it is 140 sq ft. he is incorrect. the path will have an area of (9) (40) = 360 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 240 sq ft.
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.
What is an Area?This refers to the quantity used in mathematics to show the extent of a two-dimensional region, shape, or planar lamina, in the plane.

Answer:
Step-by-step explanation:
7 and 2 are the two factors of 14.
One of them (and only 1) must be minus. That is the only way that you can get a minus 14.
The 7 must be plus. It has to larger than 2 in order to get + 5
Answer (x + 7)( x - 2) is how it factors.
Note
Always try using logic on the trinomial before going into the quadratic equation. If either the 5 is minus or the 14 is minus when one of the factors is minus. The sign in front of the middle number is the same as the larger of the two factors. So 7 must larger than 2. 7 is plus 2 is minus
