Answer:
second coupon with 15% off
Step-by-step explanation:
366.99-50= 316.99(first coupon )
366.99×( 100%-15%)= 311.9415 (second coupon)
316.99>311.9415
so the second coupon is the one she should use
A car journey has two stages.
Stage 1: The car travels 110 miles in two hours
Stage 2: The car travels 44 miles at the same average speed as stage 1
Work out the time for stage 2
Give your answer in minutes.
Answer:
48 minutes
Step-by-step explanation:
2h = 110 miles
1h = 110 ÷ 2
= 55 miles
Therefore, the speed of the entire journey is 55 miles per hour.
1h = 60 minutes
55 miles = 1h
55 miles = 60 minutes
44 miles = [tex]\frac{44}{55}[/tex] × 60 minutes
= 48 minutes

What is the equation of the line that passes through the point (4, -4) and has a
slope of –3/4?
Answer:
y=-3/4x-1
Step-by-step explanation:
y=mx+b; y is the y coordinate; m is the slope; x is the x coordinate; you have to find b. So you replace all the numbers out which is given to you;
-4=-3/4(4)+b (you multiply -3/4 by 4 and get -3)
-4=-3+b (you add 3 to both sides and get -1)
-1=b (you now found b so plug it into the equation)
y=-3/4x-1

Lisa spends part of her year as a member of the gym. She then finds a better deal at another gym, so she cancels her membership with the first gym and spends the rest of the year with the second gym. (12 months total at these gyms.) The membership to the first gym costs $75 per month, while the membership for the second gym cost $50 per month. She ends up spending a total of $775 over the course of the year.
Answer:
Number of month in first gym = 7
Number of month in second gym = 5
Step-by-step explanation:
Given:
First gym member ship cost = $75 per month
Second gym member ship cost = $50 per month
Total spending = $775
Computation:
Number of month in first gym = a
Number of month in second gym = b
So
a + b = 12....eq1
75a + 50b = 775 ....eq2
From eq 1 and 2
a = 7 month
b = 5 month
Number of month in first gym = 7
Number of month in second gym = 5

Which angle is congruent to ∠DFE?
An illustration shows two right angled triangle A B C and D E F; triangle A B C is larger than triangle D E F.
A.
∠ABC
B.
∠FDE
C.
∠FED
D.
∠ACB
The option D is correct. i.e., ∠ACB
In the given question is that
Which angle is congruent to ∠DFE
Answer is ∠DFE ~ ∠ACB
Explanation: By using the illustration shows two right angled triangle ABC and triangle DEF :
Now, If in triangles ABC and triangle DEF
Angle C = Angle F (Right angle)
CB = FE (leg)
AB = DE (hypotenuse)
then, triangle ABC is congruent to triangle DEF.
By SAS rule
Whole triangle ABC is congruent to triangle DEF. Then, we can say that
∠DFE ~ ∠ACB
Hence, The option D is correct. i.e., ∠ACB
