Sarah downloaded two apps which were 7.48 kb total. If one app was 4.78 kb, how big was the other app?
Answer:
2.7 kb
Step-by-step explanation:
Total kb = 7.48
Total apps = 2
one app = 4.78
another app = x
> 4.78 + x = 7.48
x = 7.48 – 4.78
= 2.7 kb
There are 12 brown hair teachers and 20 blond hair teachers. For every blank blond teachers there are blank brown teachers
Answer:
For every 5 blonde teachers there are 3 brown teachers.
Step-by-step explanation:
Here we have to find the ratio of blonde teachers to brown teachers
Blonde : Brown
20: 12
10:6
5:3
For every 5 blonde teachers there are 3 brown teachers.
This can be further evaluated
Blonde : Brown
5:3
dividing both sides by 5
1: 3/5
For every 1 blonde teachers there are 3/5 brown teachers. It means that the brown teachers are 2/5 less than the blonde teachers.
1-2/5= 3/5
20* 3/5= 12
A bag contains to White blocks and one red block and 3 purple blocks what is the sample space of picking a block from the bag
Answer:
1/36
Step-by-step explanation:
Probability is the likelihood of chance that an event will occur. Mathematically,
Probability = expected outcome/total outcome
If a bag contains two white blocks, one red block and 3 purple block
Total outcome = 2+1+3= 6
Probability that white ball is selected = 2/6
Probability that red ball is selected = 1/6
Probability that white ball is selected = 3/6
Probability of picking a ball is 2/6 × 1/6 × 3/6
Probability of picking a ball = 6/216
Probability of picking a ball = 1/36

This is a 30,60 90 triangle, all the angles in a triangle adds up to 180.
Use sin ratio
sin 60 = [tex]\frac{o}{4000}[/tex] o for opposite side of triangle from the 60 degree angle
o = 4000 (sin 60) = 3464.11
Use cosine
cos 30 = [tex]\frac{a}{3464.11}[/tex] a for adjacent side of triangle from the 30 degree angle
3464.11 (cos 30) = 3000.01
Each hour, every person who knows a rumor tells two other people. If one person starts the rumor, then after the first hour, three people know the rumor. The next hour, those three people each tell two more people. After eight hours, how many people will know the rumor? You do not have to include units in your answer. (I've asked this question before but the answer I got was 384 and it was incorrect)
Answer:
64
Step-by-step explanation:
In this problem n is 6 which represents the sixth and final hour of the period. Therefore gn = g6.
g1 = 2 which is the first value in the sequence which corresponds to the first hour where 2 people know the rumor.
r = the common ratio is 2, because each successive hour the people who know the rumor doubles... {2, 4, 8...}.
Substitute into equation: g6 = 2 x 26-1 = 2 x 25 = 2 x 32 = 64 Answer is 64.

James has $10 in 5-cent and 10-cent coins in his change jar and counts 157 coins in total. How many 10-cent coins does he have?
Show working out!!
Answer:
10 cent coins = 43
Step-by-step explanation:
x = 10 cent coins
y = 5 cent coins
x + y = 157, then y = 157 - x
$10 = 1000 cents
0.10x + 0.05y =1000
substitute for y:
0.10x + 0.05(157 - x) = 1000
0.10x + 7.85 - 0.05x = 1000
combine like terms:
0.05x = 2.15
x = 43
y = 114

What is rectangle?"A Rectangle is a four sided-polygon, having all the internal angles equal to 90 degrees, opposite sides are parallel and adjacent sides are perpendicular.
For the given situation,
Consider the rectangle ABCD,
The slope of [tex]AB=\frac{1}{2}[/tex]
The slope of parallel sides are equal. Here AB and CD are parallel sides.
So, slope of [tex]AB=CD[/tex].
Hence we can conclude that the slope of CD = 1/2. So, option (3) is correct.

Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. The multiplication of 4/7 x 5/6 as a fraction in the simplest form is 10/21.
What is multiplication?Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. For example, 3 × 4 means 3 is added to itself 4 times, and vice versa for the other number.
A fraction is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25.
The multiplication of the two fractions 4/7 and 5/6 can be done as,
4/7 × 5/6
Multiply the numerator and the denominator of the two fractions
= (4×5)/(7×6)
= 20/42
Dividing both the numerator and the denominator by 2 to simplify,
= 10/21
Hence, the multiplication of 4/7 x 5/6 as a fraction in the simplest form is 10/21.

Suppose jamal fell during one race and recorded a time of 210s. Which of the mean, median, and mode would be most affected
Answer:
Mean would be most affected
Step-by-step explanation:
The mean is defined as the average value . If the data has extreme values then the average value automatically changes.
The median is the value which divides the data in to two halves. It is not affected by the extreme values. The middle value remains the same.
The mode is the value which occurs repeatedly. An extreme value in a data does not affect the mode.
For example I have 5 chocolate bars of sizes 5,6,7,7,9 and another 5 chocolate bars of sizes 5,6,7,7,12
Mean for the two sizes will be 34/5= 6.8 and 37/5=7.4
The median and mode in both sets is 7
So the mean is most affected with change in value.
