Answer:
a / b = 1/7
b = a x 7
a / c = 4 /1
a = c x 4
b = a x 7
= c x 4 x 7
= c x 28
b is 28 times bigger than c
b is 28 times bigger than c. The conclusion is obtained by rearranging the equations.
What exactly are ratio and proportion?A ratio is an ordered pair of integers a and b, expressed as a/b, where b cannot be zero. A proportion is an equation that sets two ratios equal to each other.
The given ratio;
a: b = 1:7
a:c= 4:1
Rearrange the given ratio we obtained;
b = a × 7
a = c × 4
Put the value of a in b get;
b= c × 4 × 7
Hence, b is 28 times bigger than c.

Its mathematics.
Answer:
The height is 15 cm. The volume is 6000 cm³
Step-by-step explanation:
The base is square, so the sides are equal.
√400 = 20. This is the length and width of the cuboid.
The area of the base and the area of the top face are equal, so we subtract 2(400) from the total area to get the area of the remaining 4 faces.
2000 - 800 = 1200 cm²
Divide by 4 to get the area of an individual face.
1200/4 = 300 cm²
We found the width earlier: 20cm
We found the width earlier: 20cm300/20 = 15cm. This is the height.
To find Volume, multiply Area of the base times the height:
400cm²×15cm = 6000cm³
Answer:
this is your answer. best of luck.

Why do we use 'average' in our daily life?
Answer:
The term average is used frequently in everyday life to express an amount that is typical for a group of people or things. ... Averages are useful because they: summarise a large amount of data into a single value; and. indicate that there is some variability around this single value within the original data.

Answer:

Step-by-step explanation:
minus 12
Answer:
43 Degrees
Step-by-step explanation:
(3x + 16) + (6x + 1) + (82) = 180 Degrees
180 - 82 = 98 Degrees
(3x + 16) + (6x + 1) = 9x + 17
9x + 17 = 98
98 - 17 = 81
81 / 9 = 9
x = 9
6(9) + 1 = 55 Degrees
3(9) + 16 = 43 Degrees
55 + 43 + 82 = 180 Degrees

\sqrt(x^(2)-14x+49)=x-7
Answer:
infinite solutions
Step-by-step explanation:
note the expression inside the radical is a perfect square, that is
x² - 14x + 49 = (x - 7)², then
[tex]\sqrt{x^2-14x+49}[/tex] = x - 7
[tex]\sqrt{(x-7)^2}[/tex] = x- 7, that is
x - 7 = x - 7
Since both sides are the same then any value of x will make the equation true.
The equation has infinite solutions
Solve for x
x/2 + 7 = 41
Solve for x:
5x - 4 = 41
Answer:
9
Step-by-step explanation:
5x - 4 = 41
add
5x = 45
divide
x = 9
Answer:
x = 9
Step-by-step explanation:
First, add 4 to both sides.
5x - 4 + 4 = 5x (+4 and -4 cancel one another out, leaving just 5x)
41 + 4 = 45
So, we get 5x = 45
Divide by 5 on both sides.
5x/5 = x (Again, 5 is cancelled out)
45/5 = 9
We get x = 9

Solve for a.
a + (−5) = 12
Answer:
a = 17
Step-by-step explanation:
a + (-5) = 12
Open the bracket;
a - 5 = 12
Add 5 to both sides
a - 5 + 5 = 12 + 5
Therefore,
a = 17
Answer:
a=17
Step-by-step explanation:
any number plus a negative number is basically subtracting the absolute value of the negative number. so 12 + 5 = 17
ABC form a triangle where BAC equals 90° a B equals 10.8 mm and C equals 1.6 mm find the length of BC give your answer rounded to one DP
Please really need help it’s for a test
Answer:
BC = 10.9 mm
Step-by-step explanation:
The computation of the BC is given below:
Here we applied the pythagorus theorem
AB = 10.8 mm
AC = 1.6mm
BC = ?
Now as we know that
AB^2 + AC^2 = BC^2
10.8mm^2 + 1.6mm^2 = BC^2
116.64mm^2 + 2.56mm^2 = BC^2
BC = 10.9 mm

Use the Pythagoream theorm Show your work
Answer:
c=13
Step-by-step explanation:
The equation to solve the Pythagorean Theorm looks like this-
a²+b²=c²
So, lets use it to find the hypotenuse-
5²+12²=c²
(5*5)+(12*12)=(c*c)
25+144=c²
(25+144=169)
Now we have to find the square root of 169 (just put [tex]\sqrt{169[/tex] into the calculator)
c=13

Match each irrational number line on which it is represented 2.18112... 2.1823912 2.364125 2.1829391321
Answer:
See Explanation
Step-by-step explanation:
The number lines to make selection from are missing from the question.
However, I've attached 4 number lines, each of which represents each of the given irrational numbers (see attachment)
Number: 2.1823912
This is represented by number line 1
Each point of number line 3 is 0.001 units starting from 2.18;
The point which the red dot is located is between 2.182 and 2.183, but the dot is closer to 2.182.
2.1823912 and 2.1829391321 satisfy this property but number line 2 represents 2.1829391321 (see below for explanation)
So: 2.1823912 is represented by number line 1
Number: 2.1829391321
This is represented by number line 2.
Each point of number line 3 is 0.0001 units starting from 2.182;
The point which the red dot is located is between 2.1829 and 2.1830, but the dot is closer to 2.1829.
From the list of given numbers, only 2.1829391321 satisfy this property.
Number: 2.18112...
This is represented by number line 3.
Each point of number line 3 is 0.01 units starting from 2.11;
The point which the red dot is located is between 2.18 and 2.19.
If number lines 1 and 2 represent 2.1823912 and 2.1829391321, respectively, then number line 3 represents 2.18112.
Number: 2.364125
This is represented by number line 4.
Each point on this number line is 0.1 unit starting from 2.0;
The point which the red dot is located is between 2.30 and 2.40. From the list of given numbers, only 2.364125 satisfy this property.
Answer:
1: 2.1823912 2: 2.364125 3: 2.18112 4: 2.18929391321
