Step-by-step explanation:
Complete question
Dave goes into a cafe and buys 2 cups of coffee and a piece of cake.
Each
cup of coffee costs £2.75
The cake costs £2.90
Dave pays with a £10 note.
He thinks he will get more than £1.50 in change.
Is Dave correct?
Solution
Cost of one cup of coffee = £2.75
Cost of two cup of coffee = 2* £2.75 = £ 5.5
Cost of cake = £2.90
Total amount given by Dave = £10
Amount left with Dave = £10 -£ 5.5 - £2.90 = £1.60
Dave will get £1.60 change. Hence Dave is right

Applying the Pythagorean theorem, solve this triangle.
Answer:
[tex]y = \sqrt{ {14}^{2} - {10}^{2} } \\ y = \sqrt{96} \\ y = 9.8[/tex]
Answer:
Step-by-step explanation:
using pythagoras theorem
h^2=p^2+b^2
14^2=10^2+b^2
196=100+b^2
196-100=b^2
96=b^2
[tex]\sqrt{96}[/tex] =b
4[tex]\sqrt{6}[/tex] =y
What is the perimeter, to the nearest inch, of the kite?
Step-by-step explanation:
In order to calculate the height (distance BC in the diagram) you need to know the distance from point D (the closer of the two measurement points to the kite) to the point directly under the kite, B. Once you know this distance then multiplying this by the tangent of angle b will give you the height.

A standard showerhead in Jen's house dispenses 5 gallons of water per minute. Jen changed this showerhead to an energy-saving one. The equation shows the amount of water dispensed, y, as a function of the number of minutes, x, for the new showerhead.
y = 3x
How much water does Jen save each day with the change in showerheads if she uses the shower for 8 minutes each day?
a. 16 gallons
b. 17 gallons
c. 32 gallons
d. 37 gallons
Answer:
I'm pretty sure the answer is A!
Step-by-step explanation:
cause the first shower head is 5x3=40 and the second one is 3×8=24 so you that the answer and find the difference leaving you with the number 16!

Determine whether the triangle with the given side lengths is acute,
right, obtuse or not a triangle 14,16,27
Answer:
this triangle is "obtuse
Step-by-step explanation:
Since sides 14 and 16 add up to 30, which is more than the third side, 27, we DO have a triangle here. The sides of lengths 14 and 16 form an angle greater than 90 degrees, and so this triangle is "obtuse." It's not a right triangle either, because the Pythagorean Theorem is not satisfied: 14^2 + 16^2 = 452, which is NOT 27^2.
Jenna's dogs used 999 chew toys last year. The animal shelter used 2,277 277 chew toys. How many times as many chew toys did the animal shelter use? How to do
Answer: 2.28 times
Step-by-step explanation:
When finding out the number of times more that the animal shelter used chew toys than Jenna's dogs, you need to divide the number used by the animal shelter by Jenna:
= Number used by animal shelter / Number used by Jenna's dogs
= 2,277 / 999
= 2.28 times
Notice that if you multiply Jenna's dogs 999 toys by 2.28 you will get approximately 2,277.

Answer:
A
Step-by-step explanation:
In A, the number of bags that had more than 19 skittles is 7 and the number of bags that had less than 19 skittles is 16, so A is true.
In B, the median package contained 18 candies.
In C, 5 bags contained 18 candies, while there were 8 bags in total for the 17 and 20 bags.
In D, the range is the highest value minus the lowest, so it's 22-12=10.
The Fitzgerald paid $3,200 to heat their home in the year of 2018. By the end of the year 2019, they saw the cost of heating their home rose to $3,516 for the year. What could be use to find the difference in what they paid from 2918-2019?
Answer:
Substraction
Step-by-step explanation:
Given that
The amount paid in the year 2018 is $3,200
And, in the year 2019 the amount paid is $3,516'
We need to find the differnece between two years so how we can find
Basically we need to subtract the amount i.e.
= $3,516 - $3,200
= $316
hence, the difference is of $316 from 2018 to 2019

A trip, including hotel and air, is prices at $319.19 after tax. If the tax rate is 12%, calculate the price before tax that will result in this tax-included amount
Answer: $285
Step-by-step explanation:
Given
A trip costs [tex]\$319.19[/tex] after-tax inclusion
The rate of tax is 12%
Suppose x is the amount of charge before tax inclusion
We can write
[tex]\Rightarrow x+12\%x=319.19\\\Rightarrow x(1+0.12)=319.19\\\\\Rightarrow x=\dfrac{319.19}{1.12}\\\\\Rightarrow x=\$284.99\approx \$285[/tex]
The amount before tax inclusion is $285

Which description is correct about the number generator being fair or not?
A.)The number generator is fair. It picked black socks half of the time.
B.)The number generator is not fair. It picked black socks half of the time.
C.)The number generator is not fair. In three experiments, it picked black socks 50% of the time.
