Step-by-step explanation:
Other option
B: 74.9
C: 15.1
D: 15.7
Step-by-step explanation:
cosine of B = adjacent/hypot
to find hypotenuse use a^2+b^2 = c^2
which is 5 (it's a 3,4,5 triangle so it's easy)
Cosine B= 4/5
Find the sum by first finding the equivalent fractions so both of the fractions have common
denominators.

What can be concluded if ∠EJS and ∠SJV form a linear pair?
Answer:
They are supplementary.
Step-by-step explanation:
A linear pair consists of two opposite angles whose non-common sides create a straight line. If a linear pair consists of two angles, then they are supplementary
If two quantities x and y are in direct proportion, then ----------.
Answer:
x/ y = k

Which graph represents an exponential growth function?
Answer:
Graph 1 or A
Step-by-step explanation:
The graph is gradually getting bigger as it starts at the left (0,-10) and gets bigger and bigger until it hits the end of the chart, increasing endlessly. That is exponential growth.
What is an equation of the line that passes through the point (- 7, 0) and is parallel to the line x + y = 1
Answer:
y = -x - 7
Step-by-step explanation:
If two lines are parallel to each other, they have the same slope.
The first line is x + y = 1.
First, let's put this into standard form.
x + y = 1
y = -x + 1
Now we have an equation in standard form. Its slope is -1. A line parallel to this one will also have a slope of -1.
Plug this value (-1) into your standard point-slope equation of y = mx + b.
y = -x + b
To find b, we want to plug in a value that we know is on this line: in this case, it is (-7, 0). Plug in the x and y values into the x and y of the standard equation.
0 = -1(-7) + b
To find b, multiply the slope and the input of x (-7)
0 = 7 + b
Now, subtract 7 from both sides to isolate b.
-7 = b
Plug this into your standard equation.
y = -x - 7
This equation is parallel to your given equation (y = -x + 1) and contains point (-7, 0)
Hope this helps!

The sales tax in one state is 6%. Write a function rule for finding the total cost of an item with selling price x. Then find the total cost of a CD player with a selling price of $160.
f(x) = 0.06x; $9.60
f(x) = 6 + x; $161.06
f(x) = x – 6; $158.94
f(x) = 1.06x; $169.60
Answer: brainly.... D. f(x) = 1.06x; $169.60
sales tax = 6% or 6/100.
assuming tax is added onto the item:
total cost function f(x) = price + tax
however, assuming the cost price = sales price - tax, then:
f(x) = sales price - tax
This is not really a business or accounting forum, its a maths forum, so you need to be clearer about business or accounting terms such as total cost, selling price, selling cost.
Step-by-step explanation: brainly
if y= the item after tax
y=x+(x*6%) or y=x+6%
and then for the answer you would go:
y=160+6% or 160+(160*6%)= $169.60
Answer: f(x)=1.06x; $169.60

The cost of 2 pounds of coffee is $17.95. To the nearest dollar, what is the cost of 5 pounds of coffee?
Answer:
$45
Step-by-step explanation:
17.95÷2 = 8.975
8.975 × 5 = 44.875
Round to $45
Answer:
$45
Step-by-step explanation:
17.95/2 would be 8.975
then 8.975 times 5 would be 44.875
rounding it to the dollar would be about 45 dollars

Beniceo Skis 748yd in 3 mins. At this rate, How many miles does beniceo ski in an hour? (1 mi= 1,760 yd). mi=miles yd= yards
Answer:
8.5 miles
Step-by-step explanation:
3x20=60, 60 minutes also being an hour so if you multiply 748 by 20 then it gives you 14,960 annndd now you have to divide by the amount of yards in a mile 14,960/1,760=8.5
The area of the triangle above will equal one half of a rectangle that is 5 units long and __ units wide. (Input only whole numbers, such as 8.)
Answer:
2
Step-by-step explanation:
Find the diagram attached
The Base of the triangle will be equivalent to the the length of the rectangle
Since the base of the triangle is 5units, hence length of the rectangle is 5units
Similarly, the height of the triangle is corresponding to the width of the rectangle
Since the height of the triangle is 2 units, the rectangle will be 2 unts wide. Hence the required answer is 2units

X, Y and Z form the vertices of a triangle with area 59.7cm2. If XZ = 21.5cm and XY = 13.5cm, work out the acute angle ∠YXZ. Round to 1 DP.
Answer: The acute angle ∠YXZ = 24.3°.
Step-by-step explanation:
If in triangle ABC, C is the angle included between sides a and b then
Area of triangle = [tex]\dfrac12a\cdot b\cdot sin C[/tex]
here, XZ = 21.5cm and XY = 13.5cm are sides that includes acute angle ∠YXZ..
Area of a triangle = 59.7cm²
then, as per given, we have
[tex]59.7=\dfrac12(21.5)(13.5)\ \sin X\\\\\Rightarrow\ 59.7=145.125\ \sin X\\\\\Rightarrow\ \sin X = \dfrac{59.7}{145.125}\\\\\Rightarrow\ \sin X =0.41137\\\\\Rightarrow\ X = \sin ^{-1}(0.41137)\approx24.3^{\circ}[/tex]
Hence, the acute angle ∠YXZ = 24.3°.

Chris loves the series Friends. He started watching it over winter break and then started binging after school. He watched 9 episodes per week. After 4 weeks he had seen a total of 45 episodes. How many episodes did he watch over winter break? Prove it using point-slope form.
Answer: He watched 9 episodes over winter break.
Step-by-step explanation:
Given: Total episodes watched = 45
After school started , he watched 9 episodes per week.
So in 4 weeks. he watched = 9 x 4 = 36 episodes.
Number of episodes he watched over winter break = 45-36
i.e. Number of episodes he watched over winter break = 9
Hence, he watched 9 episodes over winter break.
