Answer:
4 pencils
Step-by-step explanation:
Note= pencils costing 0. 90p
Given data
Balance= £10
pen= 3*1.45= £4.35
pencils=0.90p
change= £2.05
2.05= 10-4.35-90p
solve for p
2.05= 5.65-90p
collect like terms
5.65-2.05= 0.90p
3.6=90p
divide both sides by 90
p=3.6/0.90
p=4
The number of yodelers is twice the number of xylophones, how do I write this in a equation ?
Answer:
X=(Y*2) // Y=(X/2)
Step-by-step explanation:
Xylophones = "X"
Yodelers = "Y"
First Equation: X=(Y*2) essentially just explains that the xylophones is equal to the yodelers times 2
Second Equation: Basically the same thing, but rather than multiplying the yodelers by two, it divides the xylophones in half.

Answer:
546
Step-by-step explanation:
Lateral SA = (2l + 2w)·h
= [2(10.5) + 2(2.5)] · 21
= (21 + 5) ·21
= 26(21)

Step-by-step explanation:
In triangle BAC, by Pythagoras theorem:
[tex]AC^2 = BC^2 -BA^2 [/tex]
[tex]AC^2 = (15)^2 -(9)^2 [/tex]
[tex]AC^2 = 225 - 81[/tex]
[tex]AC^2 = 144[/tex]
[tex]AC = \sqrt {144} [/tex]
[tex]AC = 12\: cm [/tex]
In triangle ABD,
[tex] \tan \angle ABD =\frac{AD}{AB} [/tex]
[tex] \tan \angle ABD =\frac{5}{9} [/tex]
[tex] \angle ABD =\tan^{-1}\frac{5}{9} [/tex]
[tex] \angle ABD =29.054604099\degree [/tex]
[tex] \angle ABD =29.05\degree [/tex]
Next, in triangle ABC, by sine rule:
[tex] \frac{\sin \angle ABC}{AC}=\frac{\sin \angle BAC}{BC}[/tex]
[tex] \frac{\sin (\angle ABD+\angle DBC) }{12}=\frac{\sin 90\degree}{15}[/tex]
[tex] \frac{\sin (29.05\degree+x) }{12}=\frac{1}{15}[/tex]
[tex] \sin (29.05\degree+x) =\frac{12}{15}[/tex]
[tex]29.05\degree+x = \sin^{-1}\frac{12}{15}[/tex]
[tex]29.05\degree+x =53.130102354\degree [/tex]
[tex]29.05\degree+x =53.13\degree [/tex]
[tex]x =53.13\degree- 29.05\degree[/tex]
[tex]x =24.08\degree [/tex]
[tex]x \approx 24\degree [/tex]

A water gauge in a pond measured 2358 in. At the beginning of the week. After five days of rain, the gauge read 3414 in. By how much did the water level rise?
Answer:
1056 inches
Step-by-step explanation:
Given that :
Initial measurement = 2358 in
Guage level after 5 days of rain (final reading) = 3414 in
Change in water level rise :
Final reading - Initial reading
(3414 - 2358) in
= 1056 inches

Which statement best describes the relationship between the lengths of the sides of the triangle shown below?
A. r squared is equal to t squared minus s squared.
B. The square root of t is equal to r plus s.
C. s squared equals t squared plus r.
D. s plus t is equal to r squared.
Answer:
the answer is c
Step-by-step explanation:
The relationship between the lengths of the sides of the triangle is as follows: r² = t² - s².
What is the right triangle?A right triangle is defined as a triangle in which one angle is a right angle or two sides are perpendicular.
The right triangle is given in the question, as shown
As per the given figure, the right triangle has
The hypotenuse = t
Let, perpendicular = r and base = s
According to Pythagoras's theorem,
In a right-angled triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.
So, perpendicular²+base²=hypotenuse²
⇒ r² + s² = t²
This can be rewritten as
⇒ r² = t² - s²
Hence, the correct answer would be an option (A).

The sum of two numbers is 63 and the difference is 5. What are the numbers?
Answer:
Numbers are 29 and 34
Step-by-step explanation:
Let x = one number
let y = second number
x + y = 63
x - y = 5
substitution method, x = 5 + y
5 + y + y = 63
2y + 5 = 63
2y = 58
y = 29
Find value of x: x - 29 = 5
x = 34

x²+y²=400
or
x²+y²=20²
