If 3/4 of ojo’s pocket money is €600.00; what is 1/8 of this pocket money?
Answer:
100
Step-by-step explanation:
explanation is shown in the picture
Let's set all the information into equations:
⇒ 3/4 of Ojo's money is €600.00 ⇒ [tex]\frac{3}{4} x = 600[/tex]
(Where x is the total amount of money)
Let's solve the equation:
⇒ to find the total amount of money that Ojo has:
[tex]\frac{3}{4}x=600\\ 3x=2400\\x=800[/tex]
⇒ total money is €800
Original question: what is 1/8 of this pocket money
[tex]\frac{1}{8} *800=100[/tex]
Answer: €100 is 1/8 of his pocket money

What is the effect on the graph of the function f(x) = x2 when f(x) is changed to f( 1 3 x) + 6? A) stretched horizontally and shifted up B) stretched vertically and shifted right C) compressed vertically and shifted left Eliminate D) compressed horizontally and shifted down
Answer:
A
Step-by-step explanation:
f(x) = x²
f(x) becomes f(13x) + 6
the "+ 6" at the end tells us already everything, because there is only one aber option listed that contains a shift up. and that is exactly what that "+ 6" did. it adds 6 to every possible y value of the function. so, the whole function moves up by 6 units.
and yes, the 13x of f(13x) stretches the function horizontally (along the x axis).
simply said, whenever the x value for the original function increased by 1, it increases for the new function by 13.

What is the length of line segment c d? round to the nearest tenth. 2.3 cm 4.0 cm 10.7 cm 18.6 cm
The value of CD is 10.7 cm , Option C is the right answer.
What is a Line Segment ?A line segment is a line of fixed measure.
From the figure , as Triangle ABC is a right angled triangle
sin 30 degree = (Perpendicular / Hypotenuse)
∠ B = 30° , AB= 10 cm
sin 30 = AC/10
AC = 5 cm.
To determine CD ,
In Triangle ADC ,
tan 25 = Perpendicular / Base
tan 25 = AC / CD
tan 25 = 5 / CD
CD = 5 / 0.4663

Mixed Number: 11 1/5
Improper Fraction: 56/5
Step-by-step explanation:
Given:
It takes 3/7 tonnes of sand to make a tonne of concrete.
Mason has 4 4/5 tonnes of sand.
To Find:
How much concrete, in tonnes, can he make?
Give your answer as a fraction in its simplest form.
Solve:
By the given , takes 3/7 tonnes of sand = tonne of concrete.
Thus, we divide the total of tonnes of sand Mason have by how many it takes to make a tonne of concrete.
Hence, we have;
[tex]4\frac{4}{5}\div \frac{3}{7}[/tex]
Convert to improper fraction;
[tex]=\frac{24}{5}\div \frac{3}{7}[/tex]
Using the fraction rule;

The measure of each anterior angle of a regular decagon is
Answer:
The measure of each interior angle of a regular decagon is 144 degrees.
Step-by-step explanation:
The measure of the interior angles of a decagon is 1440, due to the formula being (n-2)(180). Since a decagon is a ten sided shape, it would be (10-2)(180).
8 x 180= 1440.
Next, we divide the total by the number of the sides the polygon has—ten. 1440 divided by 10 is 144, so the measure of each interior angle is 144 degrees.

On a separate piece of graph paper, graph y = Ixl - 1; then click on the graph until the correct one appears.
The function y = |x| - 1 is a translation of 1 unit downwards of the parent absolute value function, and its graph is the first one shown in the images.
How to graph the function?Here we want to graph:
y = |x| - 1
Notice that if we take the parent absolute value function:
y = |x|
And we translate it one unit downwards, we will get:
y = |x| - 1
Which is the function that we want to graph.
So to select the correct graph, we need to find the one that is the parent absolute value function translated one unit downwards. It is the one with the vertex at (-1, 0), which is the graph that appears on the first image.

What is the absolute value of -6 ?
Answer:
the answer is just 6
Step-by-step explanation:
Answer:
Step-by-step explanation:
An absolute value of a number is written like this | x |, where x could be any number that you want.
The absolute value is a math function that counts from your given number to 0.
Example: If you put the number 3, the function will count from 3 to 0, and the number will be 3.
| 3 | = 3
If you input the number 8, from 8 to 0 are 8 numbers. So, the output's function will be 8.
| 8 | = 8
If you input a negative number, for example, -6, the function will do the same thing. It will count from -6 to 0. From -6 to 0, are 6 numbers.
| -6 | = 6
Any number that you input in this function, will always output the same number, but positive
| -10 | = 10
| -46348 | = 46348

What is Addition?Addition is one of the four fundamental mathematical operations, the others being subtraction, multiplication, and division. When two whole numbers are added together, the total quantity or sum of those values is obtained.
1. The annual premium cost for Michael's family is $5,260. The company pays 70% of the cost. Therefore, the cost he needs to may is,
30% of $5,260
= 0.30 × $5260
= $1578
Since the premium is needed to be paid in 52 week, therefore, the premium cost per week will be,
Premium cost = $1578/52 = $30.35
Hence, the correct option is C, $30.35.
2. Brenda annual premium is $3,500. Also, her medical bills is totaling to $12,000. Therefore, the total amount that is paid by the Brenda in purchasing Insurance and paying the bill is,
Amount Brenda spend = $3,500 + $12,000 = $15,500

How much 100% active ingredient powder would you need to add to 4 mL
of multivitamin powder that is 20% active ingredient powder in order to
strengthen the mixture to 50% active ingredient powder?
We need to add 2.4 mL of 100 % active ingredient powder to strengthen the mixture to 50% active ingredient powder
How to calculate the amount of active ingredient?The amount of each volume m = CV where
C = concentration and V = volumeThe amount of 50 % mixture, m = amount of 100 % powder + amount of 20 % powder.
M = m + m'
CV = C'V' + C"V" where
C = 50% concentration = 0.5, V = 50 % Volume, C' = 100 % concentration = 1, V' = 100 % volume, C" = 20 % concentration = 0.2 and V" = 20 % volume = 4 mLSo, CV = C'V' + C"V"
0.5V = 1 × V' + 0.2 × 4
0.5V = V' + 0.8 (1)
Also, we have that the total volume V = V' + V"
V = V' + 4 (2)
Substituting equation (2)into (1), we have
0.5V = V' + 0.8
0.5(V' + 4) = V' + 0.8
0.5V' + 0.5 × 4 = V' + 0.8
0.5V' + 2 = V' + 0.8
0.5V' - V' = 0.8 - 2
-0.5V' = -1.2
V' = -1.2/-0.5
V' = 2.4 mL
So, we need to add 2.4 mL of 100 % active ingredient powder to strengthen the mixture to 50% active ingredient powder
