TV Cabinet TV screens are measured on the diagonal. If we have a TV-cabinet that is 72 inches long and 64 inches high, how large a TV could we put in the space (leave 2-inches on all sides for the edging of the TV)? Round your answer to the nearest tenth.
Answers
Answer:
94inStep-by-step explanation:
We are expected to solve for the diagonal of a rectangular shape.
given that the length, l=72in
width, w=64in
we can apply the Pythagoras theorem to solve for the diagonal since it corresponds to the hypotenuse of the rectangle
note: we are to leave 2-inches on all sides for the edging of the TV
l=72-2= 70 in
w=64-2=62
diag=√l^2+w^2
diag=√70^2+62^2
diag=√4900+3844
diag=√8744
diag=93.50 in
to the nearest tenth, it is 94in

Evaluate f(x)=x+6 when x=−2,0, and 5.
f(−2)=
f(0)=
f(5)=
thank you
Answers
Answer:
f(-2) = 4
f(0) = 6
f(5) = 11
Step-by-step explanation:
You just need to plug in the different values of x into the equation
f(x)=x+6
When x = -2, then f(-2) = -2 + 6 = 4
When x = 0, then f(0) = 0 + 6 = 6
When x = 5, then f(5) = 5 + 6 = 11
f(5) = 11 , f(0) = 6 , f(-2) = 4
Given expression:
f(x) = x + 6
Find:
f(−2), f(0), f(5)
Computation:
f(x) = x + 6
When x = -2
f(-2) = -2 + 6
f(-2) = 4
When x = 0
f(0) = 0 + 6
f(0) = 6
When x = 5
f(5) = 5 + 6
f(5) = 11

3. Fifteen bicycles are produced each hour at the
Speedy Bike Works. Show that the relationship
between the number of bikes produced and the
number of hours is a proportional relationship.
Then write an equation for the relationship.
Answers
Answer:
The equation is: y = 15·x
Step-by-step explanation:
It is provided that at the Speedy Bike Works, 15 bicycles are produced each hour.
Consider the table below.
Number of Hours: 1 3 6 10
Number of Bicycles Produced: 15 45 90 150
Compute the ratio of number of bicycles produced and number of hours for every data above as follows:
[tex]\text{1 hour}=\frac{15}{1}=15:1\\\\\text{3 hour}=\frac{45}{3}=\frac{15}{1}=15:1\\\\\text{6 hour}=\frac{90}{6}=\frac{15}{1}=15:1\\\\\text{10 hour}=\frac{150}{10}=\frac{15}{1}=15:1[/tex]
The ratio of the number of bicycles produced and number of hours is same for every data value.
Thus, the relationship between the number of bicycles produced and number of hours is proportional.
The equation for the relationship is:
y = 15·x
y = number of bicycles produced
x = number of hours

Naoko is building a small art shed in the backyard. She created a blueprint of the floor plan with a scale of 1⁄4 in. To 1 ft. According to the blueprint, the art space has dimensions of 2 1/2 in. By 1 in. What are the dimensions of her art shed in feet?
Answers
Answer: 10 feet by 4feet
Step-by-step explanation:
From the question, we are informed that Naoko is building a small art shed in the backyard and that she created a blueprint of the floor plan with a scale of 1⁄4 in. to 1 ft. This means that 1 inch will be to 4 feet.
Since the art space has dimensions of 2 1/2 in. by 1 in. This will be:
= (2 1/2 × 4) by (1 × 4)
= 10 feet by 4 feet
The dimensions of her art shed in feet are 10 feet by 4 feet.

The cost C , in £, of a monthly phone contract is made up of the fixed line rental L , in £, and the price P , in £ ,of the calls made. Enter a formula for the cost and, enter the cost if the line rental is £10 and the price of calls made is £28.
Answers
Answer:
C = L + P
C = £38
Step-by-step explanation:
Given that :
Cost (C) is given by :
Sum of fixed line rental (L) ; price (P) of calls made.
Hence,
Cost formula;
C = L + P
Cost if the line rental is £10 and the price of calls made is £28.
C = L + P
If L = £10 ; P = £28
C = £10 + £28
C = £38

The local furniture store pays $300 for a dining room table and sells it with a 40% markup.
What is the selling price of the dining room table?
Answers
Answer:
$420
Step-by-step explanation:
The wholesale price is $300 and the markup is 40% of that, or
0.40($300) = $120
and so the selling price is $300 + $120 = $420
An easier way to calculate this is to multiply $300 by (1.00 + 0.40), or (1.40), which again comes out to $420.

Fitness For cardiovascular exercise, you do a combination of walking and running
for 60 minutes. During the 60 minutes, you end up running twice as much as
walking. Let x represent the number of minutes you ran and y represent the
number of minutes you walked. How many minutes did you run and how many
did you walk?
Answers
Answer:
You walked for 20 minutes and ran for 40 minutes
Step-by-step explanation:
System of Equations
Let x = the number of minutes you ran
y = the number of minutes you walked
Walking and running takes a total of 60 minutes, thus:
[tex]x+y=60\qquad\qquad [1][/tex]
Running time is twice as much as walking time, thus:
[tex]x=2y\qquad\qquad [2][/tex]
Solve the system by substitution. Taking x from [2] and substitute in [1]:
2y+y=60
Simplifying:
3y=60
Solving:
y=60/3=20
Calculate x from [2]:
x=2*20=40
You walked for 20 minutes and ran for 40 minutes
