Alex only keeps ten pence coins and some twenty pence coins in
his coin box. He has a total of 18 coins which amounts to £2.30.
Work out the number of ten pence coins and twenty pence coins
in Alex's coin box.
Answers
Answer:
In the box. we have 5 20 pence coins and 13 10 pence coins
Step-by-step explanation:
Let the number of 10 pence coins be x and the number of 20 pence coins be y
The sum of these numbers is 18
Thus;
x + y = 18•••••••(i)
Writing the value in pence only
£2.30 * 100 = 230 pence
Now we have that;
total 10 pence coin amount = 10 * x = 10x
Total 20 pence coin amount = 20 * x = 20y
10x + 20y = 230
x + 2y = 23 •••••••(ii)
from ii;
x = 23-2y
Substitute this into i
23-2y + y = 18
23-18 = 2y-y
y = 5
Recall;
x + y = 18
x + 5 = 18
x = 18-5
x = 13

.The measures of the angles of a triangle are in the extended ratio 6: 1: 5. What is the measure of the largest angle?
Answers
Answer:
90
Step-by-step explanation:
Ratio = 6 : 1 : 5
Angles are 6x ,x , 5x
Sum of all the angles of the triangle = 180
6x +x +5x = 180
12x = 180
x = 180/12
x = 15
Largest angle = 6x = 6*15 = 90

Sarah and Nathan each picked a bucket of strawberries. Sarah picked 4 1/4 and Nathan picked 3 3/4. How much more did Sarah pick than Nathan?
Answers
Answer: 1/2 buckets
Step-by-step explanation:
Sarah picked 4¹/₄ buckets of grapes and Nathan picked 3³/₄ buckets.
To find out how much Sarah picked more than Nathan, simply subtract Nathan's buckets from Sarah's.
First convert the fractions to improper fractions:
4¹/₄ = 17/4
3³/₄ = 15/4
As the have the same denominator, you can directly subtract them:
= 17/4 - 15/4
= 2/4
= 1/2 buckets

(Help please) Find both the perimeter and the area of the following rectangle
2x+3
X+6
Perimeter:_____
Area:____
Answers
Given:
Length of a rectangle = (2x+3) units
Width of the rectangle = (x+6) units
To find:
The perimeter and the area of the rectangle.
Solution:
We know that, the perimeter of the rectangle is
[tex]Perimeter=2(Length+Width)[/tex]
[tex]Perimeter=2((2x+3)+(x+6))[/tex]
[tex]Perimeter=2(3x+9)[/tex]
[tex]Perimeter=6x+18[/tex]
The area of rectangle is
[tex]Area=Length\times width[/tex]
[tex]Area=(2x+3)\times (x+6)[/tex]
[tex]Area=2x^2+12x+3x+18[/tex]
[tex]Area=2x^2+15x+18[/tex]
Therefore, [tex]Perimeter=6x+18[/tex] and [tex]Area=2x^2+15x+18[/tex].

The blueprint for an office building uses a scale of 2 cm.:3.5 m. The height of the actual office building is 259 m. What is the height of the office building on the blueprint?
Answers
Answer:
150 cm
Step-by-step explanation:
So the scale is 2 cm on the blueprint = 3.5 meters in real life.
Basically you can just divide the height of the building by 3.5 meters:
259/3.5=75
There are 75, 3.5 meters in 259 meters
Since 3.5 meters on the print is 2 cm
You need to multiply the number of 3.5 meters by 2:
75*2=150
150 cm
