follow me
mark me as BRAINLIEST
100%sure
Answer:
5 - [tex]\sqrt{7}[/tex]
Step-by-step explanation:
To rationalise the factor multiply by the conjugate factor
The conjugate of 5 + [tex]\sqrt{7}[/tex] is 5 - [tex]\sqrt{7}[/tex] , then
(5 + [tex]\sqrt{7}[/tex] )(5 - [tex]\sqrt{7}[/tex] ) ← expand using FOIL
= 5² - ([tex]\sqrt{7}[/tex] )²
= 25 - 7
= 18

Answer:
A. [tex]2x^2y\sqrt[3]{7xy^2}[/tex]
Step-by-step explanation:
When given the following problem,
[tex]\sqrt[3]{56x^7y^5}[/tex]
The problem asks one to find the cube root of the value under the radical. The cube root of a number is essentially a value that must be multiplied by itself three times to get the result under the radical. An easy way to do this is to prime factorize the value under the radical sign. This will allow one to see the components of the number, thus making it easier to take value out of the radical;
[tex]=\sqrt[3]{7*2^3x^7y^5}[/tex]
Now divide each of the exponents by (3), write the whole result outside the radical, and the remainder under the radical,
[tex]=2x^2y\sqrt[3]{7xy^2}[/tex]

Answer:60
Step-by-step explanation:20x6=120 120/2=60
Answer:
200 cubic centimetres
Step-by-step explanation:
Length = [tex]20 \: cm[/tex]
Width = [tex]6 \: cm[/tex]
Height = [tex]5 \: cm[/tex]
Volume = [tex] \frac{1}{3} \times w \times l \times h[/tex]
[tex] = \frac{1}{3} \times 20 \times 6 \times 5[/tex]
[tex] = \frac{20}{3} \times 6 \times 5[/tex]
[tex] = \frac{20}{3} \times (3(2)) \times 5[/tex]
[tex] = 20 \times 2 \times 5[/tex]
[tex] = 40 \times 5[/tex]
[tex] = 200 \: {cm}^{2} [/tex]

This system of inequalities models the scenario:
2x + y ≤ 8
x + y ≥ 4
Part A: Describe the graph of the system of inequalities, including shading and the types of lines graphed. Provide a description of the solution set.
Answer:
Solution set include (1,5), (1,4)
Step-by-step explanation:
To solve, you would have to graph both lines, and shade, the sections that are applicable. For Example is if it tells you the 2x+y is less than or equal to 8, you would shade it.
The Solution set would be anything in the overlapping area between both line's shades.

Step-by-step explanation:
simply devide by 100,2,5% is out of 100%
Express 1800 ml as percentage of 2.1 L
Answer:
1400 ml is 66.67% of 2.1 L
To express one number as a percentage of another, form a fraction using these two numbers and multiply it by 100. Note that the number that is being expressed as a percentage is placed in the numerator of the fraction.
The library has 215 new books 155 of those books already have been put on shelves .the rest of the books are divide equally amount 5 boxes
Answer:
Ok to do this question we must first put it into a algebraic equation.
215=5x-155
This is are equation. lets first get rid of the 155 by adding it to the 215 which is 370.
370=5x
Ok now we will divide 370 by 5 which is 74.
x=74

Help Please question in the picture
Answer:
Option (1)
Step-by-step explanation:
Given figure in the picture has two parallel sides and fulfilling the property of a trapezium.
Since, an isosceles trapezium contains two parallel sides and other pair of the sides are equal in length.
Therefore, the given trapezium can't be an isosceles trapezium.
Option (1) will be the correct option.

A=1/2 h(x+y) make x the subject
Answer:
Step-by-step explanation:
A =1/2 *h (x+y)
A =hx+hy/2
A*2 =hx+hy
2A =hx+hy
2A - hy = hx
(2A -hy)/h = x
Answer:
x = [tex]\frac{2A-hy}{h}[/tex]
Step-by-step explanation:
Given
A = [tex]\frac{1}{2}[/tex] h(x + y) ← multiply both sides by 2 to clear the fraction
2A = h(x + y) ← distribute
2A = hx + hy ( subtract hy from both sides )
2A - hy = hx ( divide both sides by h )
[tex]\frac{2A-hy}{h}[/tex] = x

If f(x) = 5x² – 2x + 7 and g(x) = -2x2 +6x + 3
then f (x)-g(x) =
Answer:
7x² - 8x + 4
Step-by-step explanation:
f(x) - g(x)
= 5x² - 2x + 7 - (- 2x² + 6x + 3) ← distribute parenthesis by - 1
= 5x² - 2x + 7 + 2x² - 6x - 3 ← collect like terms
= 7x² - 8x + 4

Find the roots of the quadratic equation (4p-1)² = 4p²
( Please show me how it works , Thankiuuu ༎ຶ‿༎ຶ )
Answer:
p = 1/2
Step-by-step explanation:
(4p - 1)^2 = 4p^2
(4p - 1)^2 =(2p)^2
4p - 1 =[tex]\sqrt{(2p)^2}[/tex]
4p - 1 =2p
4p - 2p =1

Adwoa received a commission of 20% on bread she sold. In one week, Adwoa's commission was Gh¢540. How much bread did she sell during that week. And find her average daily commission.
Answer:
a). 2700
b). 385.7
Step-by-step explanation:
According to the Question,
Given that, Adwoa received a commission of 20% on the bread she sold. In one week, Adwoa's commission was 540.
let x be the total cost of bread she sells during the week.
a). Thus, 20% of x = 540
x = 540 × (100/20) ⇒ 2700 is the total cost of bread she sells during the week.
b). Now, her average daily commission is 2700/7 ⇒ 385.7
The graph shows the absolute value parent function.
5
-5
5
-5
Which statement best describes the function?
O A. The function is increasing when x < 0.
Answer:
C, never negative
absolute value is like asking for "how much away from zero", so -5 is 5 away from zero.
The graph of the function is increasing when x>0.
What is graph?Graph a diagram showing the relation between variable quantities, typically of two variables, each measured along one of a pair of axes at right angles.
here, we have,
We know, cube root parent is:
The basic parent cube root function is of the form f (x) = ∛x. It increases on the interval (-∞, ∞). It increases on the interval [0, ∞). It is positive on (0, ∞) and negative on (-∞, 0). It is a non-negative function always (on [0, ∞)). Its absolute min is 0 but no absolute max. Its domain and range is the set of all real numbers.
Given,
The function f(x) = ∛x
Let x = 1, we get f(x) = 1,
x =2, f(x) = 8
if x =3, f(x) = 27.
As we know, with increase in the value of x, the value of f(x) is also increasing.

b = 8
Step-by-step explanation:
a (1/2) ^3 = (1/2) *(1/2) * (1/2) = 1/8
b( 1/2 ) ^ -3 The negative exponent means 1 / (1/2)^3 = 1/ (1/8) = 8

What number is equal to 58 × 5-6? 5 -2 5 2 5 48 5 -14
Step-by-step explanation:
please, write the problem statement properly. it is not clear what you are asking for.
for example, the way how you wrote it, the first expression would be
58 × 5 - 6
and that would be (remember, multiplication and division happen before any additions or subtractions)
58 × 5 - 6 = 290 - 6 = 284
nothing on the right side of numbers fits to that.
so, I am speculating. did you mean
58 × (5-6) ?
in that case we get
58 × (5-6) = 58 × (-1) = -58
and then I assume that the right side of all the numbers includes also operations (like +, -, ...), as I see no -58 in the list of numbers.
and then I just propose that the right side could look like
-2×5 - 48 (which would also be -58).
but again, this could be something completely different.
so, please, write your problem statement again. and carefully.
