Divide £84 in the ratio 5 : 2 *
Answer:
£60 : £24
Step-by-step explanation:
Let's put the ratio into one number.
5 + 2 = 7
There are 7 parts in our ratio, so let's find one part.
£84 ÷ 7 = £12
Going back to the original ratio, we can multiply one part by 5 and 2.
£12 × 5 = £60
£12 × 2 = £24
And it all adds back together to make £84.
£60 + £24 = £84

Step-by-step explanation:
(-2,2)(-1,2)(0,0)(1,-2)(2,1) the x does not repeat so it is a function
how many solutions does x=-2 have
Answer:
One solution
Step-by-step explanation:
In a one- variable equation has infinitely many solutions when solving results in a true statement, such as 2=2
In a one- variable equation has one solution when solving results in one value for the variable, such as x = 5
In a one - variable equation has no solution when solving results in an untrue statement, such as 2=3
So, in this case the result x = -2 belongs to the 2nd sentence where it says one solution.

What is 11 divided by 5 as a fraction
11 divided by 5 is equal to the fraction 11/5, which can also be expressed as the mixed number [tex]2\frac{1}{5}[/tex] .
What is 11 divided by 5 as a fraction?To convert the division of 11 by 5 into a fraction, we can express it as a ratio of two integers. Here's how we can derive the fraction:
When we divide 11 by 5, we get a quotient of 2 with a remainder of 1. So, we can write the division as:
11 ÷ 5 = 2 + 1/5
Since 2 is a whole number, we can express it as a fraction with a denominator of 1:
2 = 2/1
Now, we can rewrite the division using the same denominator:
11/5 = 2/1 + 1/5
To combine the fractions, we need a common denominator. The least common multiple (LCM) of 1 and 5 is 5. Therefore, we can multiply the fractions by appropriate values to make their denominators equal to 5:
11/5 = (2/1) × (5/5) + (1/5) = 10/5 + 1/5
Now that the denominators are the same, we can add the fractions:
11/5 = (10 + 1)/5 = 11/5
Therefore, the division of 11 by 5 can be expressed as the fraction 11/5.
The fraction 11/5 represents the result of dividing 11 into 5 equal parts. Each part would be equal to 11/5. It can also be simplified to a mixed number as 2 1/5, where the whole number part is 2 and the fractional part is 1/5.
So, 11 divided by 5 is equal to the fraction 11/5, which can also be expressed as the mixed number 2 1/5.

Answer:
145) A
146) C
147) B
148) D
Step-by-step explanation:
_____________________145_____________________
Starting with number 145 it mentions that XY = 24 and XY:YZ = 1:2.
XY:YZ means ratio of XY over YZ so for each 1 XY there is 2 YZ.
Moving on and taking note that XY=24 so this means that,
[tex]\frac{XY}{YZ} =\frac{24}{YZ}= \frac{1}{2}[/tex]
Solving the above expression by cross multiplying 24x2 will give you YZ = 48. The same method applies to #146 and #148 the next questions.
_____________________146_____________________
YZ = 9 and XY:YZ=2:3
[tex]\frac{XY}{YZ} =\frac{XY}{9} =\frac{2}{3}[/tex]
XY= (2x9)/3 = 6
XY = 6
_____________________147_____________________
Given:
XZ = 2ft
YZ = 18in
In this question, you will have to refer to the proportion line given above the questions. It mentions that XZ = 2ft (which is the whole line) and YZ = 18in (which is from Y to Z). Take note that the units are not the same.
They're looking for XY which is the only unknown length in the given proportion line. To get XY you'll have to subtract XZ - YZ, but the units are not the same so you'll have to convert feet to inches since the answer options are given in inches.
Convert 2ft to inches:
To convert from feet to inches you'll have to multiply by 12 so 2x12 = 24.
Therefore, XZ = 24in
Now we subtract:
XZ - YZ = XY
24 - 18 = 6in
_____________________148_____________________
YZ = 1ft
XY: YZ = 1:4
YZ is given in feet and the answers are provided in inches so we'll have to convert.
1 x 12 = 12in
YZ = 12in
[tex]\frac{XY}{YZ} =\frac{XY}{12} =\frac{1}{4}[/tex]
XY = (1x12)/4 = 3in

Tom drives 200 miles in 4 hours, he drives the first 32 miles at an average speed of 64mph, work out his average speed for the rest of the journey.
Answer: Tom's average speed for the rest of the journey = 48mph
Step-by-step explanation:
Total distance driven = 200 miles
total time taken = 4hours
first 32 miles , he drove at an average speed of 64mph, To find the amount of time taken for the first 32 miles,
We Use the formulae
Speed = distance / time
Time = Distance / speed
=32/64 = 1/2 =0.5 hours
The remaining distance = Total distance covered - first 32 miles covered
= 200 -32= 168 miles
The remaining time for rest of journey = Total time taken - time covered in the first 32miles
4hours - 0.5 hours
=3.5 hours
Therefore Average speed for the rest of the journey = Distance for the remaining journey/ remaining time
168miles/ 3.5hours = 48mph

These figures are congruent. What series of transformations moves pentagon
FGHIJ onto pentagon F'G'HTJ'?
Answer: C
Step-by-step explanation:
It would have to be a translation and another translation because the preimage of the figure is the same orientation as the image therefore it can't have a rotation or reflection included in it so the answer would be C. Hope this helps :)!
Option (C) is correct.
What are congruent sides and a translation?
In geometry, two figures or objects are congruent if they have the same shape and size, or if one has the same shape and size as the mirror image of the other.
A translation is a type of transformation that takes each point in a figure and slides it the same distance in the same direction.
How to find FGHIJ onto pentagon F'G'HTJ'?
It would have to be a translation and another translation because the preimage of the figure is the same orientation as the image
Thus it can't have a rotation or reflection included in it so the answer would be C.
