Answer:
Rhian did better in the Math test.
Step-by-step explanation:
Given: Rhian scored [tex]14[/tex] out of [tex]17[/tex] in a Math test. In the English test she scored [tex]31[/tex] out of [tex]39[/tex].
To find: In which test did she do better?
Solution:
We have,
Rhian scored [tex]14[/tex] out of [tex]17[/tex] in a Math test.
Rhian scored [tex]31[/tex] out of [tex]39[/tex] in an English test.
So, first we need to find the percentage of the marks scored.
Percentage in the Math test [tex]=\frac{14}{17}\times100=82.35 \%[/tex].
Percentage in the English test [tex]=\frac{31}{39}\times100= 79.49\%[/tex].
Clearly, the percentage in the Math test is greater than the percentage in the English test.
So, Rhian did better in the Math test.
Answer:
maths
Step-by-step explanation:
as the percentage for maths is 82.
Two snakes race the speed of the first is 24 1/2 inches per minute and the speed of the other is 26 inches per minute how far apart with they be in 3 min? 10 min?
Answer:
In 3 min = 4 1/2
10 min = 15
If you multiply both of the snakes speed by the specific amount of minutes and then subtract both of the sums you'll get the answer :)
Paulo catches a 7.45 am tram to school. During a period of 79 days, he arrives at school on time 53 occasions. Estimate the probability Paulo:
arrives on time: arrives late:
Answer:
On time: 0.67
Late: 0.33
Step-by-step explanation:
Probabilities
One approach to estimating the probability of occurrence of an event is to record the number of times that event happens (e) and compare it with the total number of trials (n).
The probability can be estimated with the formula:
[tex]\displaystyle P=\frac{e}{n}[/tex]
And the probability that the event doesn't occur is
Q = 1 - P
Paulo arrives on time to school e=53 times out of n=79 times. The probability that he arrives on time is:
[tex]\displaystyle P=\frac{53}{79}[/tex]
P = 0.67
And the probability he arrives late is:
Q = 1 - 0.67 = 0.33
(-3, 11) a solution to the systems of equations: x – 3y = -36 and 3x + 4y = 48
true or false
Answer:
TRUE and FALSE (please look at step-by-step)
Step-by-step explanation:
How to know if it's true or false, you just simply plug in the given numbers to the x and y values.
x = -3
y = 11
for the x - 3y = -36 equation:
-3 -3(11) = -36
-3 - 33 = -36
This equation is true.
for the 3x + 4y = 48 equation:
3(-3) + 4(11) = 48
-9 + 44 = 35
This equation is false.
[Find all the missing side and angles of this triangle]
Step-by-step explanation:
We have AB = 7, Angle ABC = 70°
and Angle ACB = 90°.
Angle BAC = 180° - 70° - 90° = 20°
(Sum of angles in a triangle = 180°)
Using Trignometry,
AC = 7sin70° = 6.58.
BC = 7cos70° = 2.39.

The diagram shows a sector of a circle radius 10 cm.
Find the area of the sector, giving
your answer correct to 1 decimal place.
135°
10 cm
please give the working out aswell !!
Answer:
Area of sector = 117.6 cm²
Step-by-step explanation:
Radius of sector r = 10 cm
Angle Ф = 135°
We need to find Area of sector
The formula used is: [tex]\mathbf{Area\:of\:Sector=\frac{\theta}{360^{\circ}}\times \pi r^2}[/tex]
Where Ф is the angle, and r is the radius.
Putting values and finding area of sector
[tex]\mathbf{Area\:of\:Sector=\frac{\theta}{360^{\circ}}\times \pi r^2}\\Area\:of\:Sector=\frac{135}{360}\times 3.14 (10)^2\\Area\:of\:Sector=0.375 \times 3.14 \times 100\\Area\:of\:Sector=117.75[/tex]
Now, rounding off answer to 1 decimal place:
[tex]Area\:of\:Sector=117.6\: cm^2[/tex]
So, Area of sector = 117.6 cm²

121ײ + 110 +25 y²
Answer:
(5y+11)²
Step-by-step explanation:
The given expression is :
25y²+110y+121
We need to factors of the given expression.
We know that, (11)² = 121
5² = 25
We can write the given expression as :
25y²+110y+121 = (5y)² + 2(5y)(11) +11²
Using identity : (a+b)² = a²+2ab+b²
25y²+110y+121 = (5y+11)²
Hence, the factors of 25y²+110y+121 is (5y+11)².

What is the slope of the line with equation y=5x+7 ?
Answer:
the slope is 5
explanation:
goes up 5 and right 1
Choose the correct way to end the sentence.
The line x-2y=4 and y=2x -2 are
A parallel
B neither
C perpendicular
Answer: B) neither
================================================
Let's isolate y in the first equation. This way we can find the slope.
x-2y = 4
-2y = 4-x
-2y = -x+4
y = (-x+4)/(-2)
y = -x/(-2) + 4/(-2)
y = (1/2)x - 2
This matches with y = mx+b form with m = 1/2 being the slope.
The slope of y = 2x-2 is m = 2
------------------------------
The slope of the first line is 1/2 and the slope of the second line is 2.
Since the two slopes (1/2 and 2) are not equal, this means the lines are not parallel.
Also, the two slopes do not multiply to -1, so the lines aren't perpendicular either.
This leads to B) neither as the final answer.
Write the equation of a line that is PERPENDICULAR to the line y=3x-4 and passes through the point (-6,1)
Answer: y = -1/3x - 1
