Answer 21/20
Step-by-step explanation:
a carpenter can make 30 chairs, 25 tables and 15 beds in a month. what proportion of the carpenter's output is bed.
Answer:
3/14
Step-by-step explanation:
Express the beds as a fraction of the total output.
Beds = 15
Total output = 30 + 25 + 15 = 70
Proportion that is beds = 15/70
15/70 = 3/14

No. of wooden boxes is less than 9
x< 9
No. of plastic boxes is not more than 10
y ≤ 10
Weight equation
Wood box 6 kg Plastic box 3 kg total 36 kg
which means that the weight that can be carried must be greater than or equal to the actual weight
6x + 3y ≥ 36
Volume equation
Wood box 0.25 m² Plastic box 0.5 m² total 3 m²
which means that the capacity of boxes must be greater than or equal to the capacity of actual load
0.25x + 0.5y ≥ 3
4) Let the no. of RM100 tickets be x and no. of RM150 tickets be y
no. of RM100 tickets is more than no. of RM150 tickets.
x > y
Total price exceeds 3000
100x + 150y > 3000
i think of a number, multiply it by itself and then add 6 to the result
Answer:
x²+6
Step-by-step explanation:
Let the number be x
⇒ Multiplying it by itself makes x × x = x²
⇒ Adding 6 makes it x²+6
Answer:
[tex] {x}^{2} + 6[/tex]
Step-by-step explanation:
thinked number = x
multiply by itself = x *x
[tex]x \times x \\ = {x}^{2} [/tex]
add 6 =+6
[tex] {x}^{2} + 6[/tex]

A force of 76 N is applied to an area of 490 cm2. Calculate the pressure in N/m2. Give your answer to the nearest integer.
Answer:
Given
Hope it helps
Step-by-step explanation:
Pressure is the force per unit perpendicular area over which the force is applied
p=F/A
Where f is force and a is area
So P
= F/A
= 76N / 0.049m2
= (76/0.049) Nm2
= 76000/49
= 1551.02
Or 1551 N/m2
Bill has to figure out the area of his square yard.he knows that one side of his yard is equal to the length of his garage. The dimensions of his rectangular garage are 17 by 10 what is the area of the yard ? Help!
Answer:
Area of square yard is 289 square units.
Step-by-step explanation:
Problem: find the area of yard
Given
side measure of yard is equal to length of garage.
Dimension of rectangular garage : 17 by 10
we know that rectangle consist of 4 sides with opposite of equal length.
Additionally in rectangle value of length is always greater than measure than width of rectangle.
Thus, in the given dimension 17 by 10, 17 is greater than 10.
hence length of garage is 17
this length is equal to side of square yard.
Thus, measure of yard = 17
we know area of square is given by = [tex]side^2[/tex]
thus, area of square yard = [tex]17^2[/tex] = 289
Area of square yard is 289 square units.
A sales girl is paid a basic wage of $225 per week. In addition she is paid a commission of 5% on the value of goods she sells. How much commission will she be paid on sales amounting to $1,525 and what is her gross wage for the week?
Answer:
Commission = $76.25
Gross wage = $301.25
Step-by-step explanation:
First, we know her commission is 5% of her sales which means the commission she will receive is;
5% * $1525
[tex]\frac{5}{100} * 1525[/tex]
= $76.25
∴ Her total wage for the week will be;
$225 + $76.25
= $301.25

Answer:
- 3 ≤ x < 2
Step-by-step explanation:
The line extends from - 3 to 2
The closed circle at - 3 means x can equal - 3
The open circle at 2 means that x cannot equal 2, thus
- 3 ≤ x < 2

What is the measure of angle FMG?
Trapezoid EFGH is given. M is the midpoint of side GH. Points E and F are joined to M to form 3 equal triangles EHM, EMF and MFG.
Answer:
[tex]\angle FMG=60^{\circ}[/tex]
Step-by-step explanation:
Given: [tex]\angle EMG=120^{\circ}\,,\,\angle EMF=60^{\circ}[/tex]
To find: [tex]\angle FMG[/tex]
Solution:
A trapezoid is a quadrilateral in which one pair of opposite sides is parallel. A trapezoid in which opposite angles are supplementary is known as an isosceles trapezoid. In any isosceles trapezoid, two opposite sides are parallel, and the two other sides are equal to each other.
Consider the figure:
[tex]\angle FMG=\angle EMG-\angle EMF\\=120^{\circ}-60^{\circ}\\=60^{\circ}[/tex]

Part A: Create a fourth-degree polynomial with three terms in standard form. How do you know it is in standard form?
Part B: Explain the closure property as it relates to addition of polynomials. Give an example.
Answer:
Part A: x⁴ + x³ + x²
Part B: (4·x + 2) + (-5·x + 6) = -x + 8
Step-by-step explanation:
Part A:
We note that standard form means that the terms of the polynomial are arranged in order starting from the the largest exponential of the polynomial to the smallest exponent
Therefore, we have
x⁴ + x³ + x² is a fourth-degree polynomial with three terms in standard form
It is known that the above polynomial is in standard form based on its ordered arrangement from the largest exponential to the smallest exponential
Part B:
Polynomial are closed under addition, that is when two polynomials are added only the coefficients change as the exponents and variables remain unchanged as follows;
(4·x + 2) + (-5·x + 6)
= 4·x + 2 - 5·x + 6
= 4·x - 5·x + 2 + 6
= -x + 8 which is a polynomial with the same variable and exponent.

Help plzz!! Can you explain how you got to the answer also & Thank you!!
Answer:
x = 4
Step-by-step explanation:
M is the midpoint of segment VW. Hence, we have MV = MW
As we can see from the picture: MV = 4x - 1 and MW = 3x + 3.
Therefore, we have an equation as below:
4x - 1 = 3x + 3
Let's move all the x-components to the left and other numbers to the right for working out x. The new equation is presented as:
4x - 3x = 1 + 3
We notice that the sign of 3x has been changed from + to -, and the sign of 1 has been changed from - to + (this is the rule used to change the sign of a number in an equation when you move that number from one side to the other side)
Now we perform the subtraction on the left side and the addition on the right side to simplify the equation. We finally get:
x = 4
This is the final answer.
I hope this helps!
For f(x) = 2x + 1 and g(x) = x^2- 7, find (f - g)(x). ?
Answer:
(f-g)(x)=-x^(2)+2x+8
the solutions are:
x=4 or x=-2
Step-by-step explanation:
(f-g)(x)=2x+1-(x^(2)-7)
(f-g)(x)=-x^(2)+2x+1+7
(f-g)(x)=-x^(2)+2x+8
does this help or should I solve for the zeros/solutions of this quadratic equation?
then:
-x^(2)+2x+8=0
-(x^(2)-2x-8)=0
x^(2)-2x-8=0
(x-4)(x+2)=0
x=4 or x=-2
Answer:
The required answer is: -x^2+2x+8
Step-by-step explanation:
We have been given the two function:
f(x)=2x+1
And g(x)=x^2-7
We have to find (f-g)(x):
(f-g)(x)=f(x)-g(x)
(2x+1)-(x^2-7)
2x+1-x^2+7
-x^2+2x+8
Hence, the required answer is: -x^2+2x+8

In a village the number of houses and the number of flats are in the ration9:5 the number of flats and the number pf bungalows are in the ratio 10:3 there are 30 bungalows in the village. How many houses are there in the village?
Answer: 180 houses
Step-by-step explanation:
From the question, we are informed that in a village the number of houses and the number of flats are in the ratio 9:5 while the number of flats and the number of bungalows are in the ratio 10:3 and that there are 30 bungalows in the village.
Since the ratio of the number of flats and the number of bungalows are in the ratio 10:3 and there are 30 bungalows in the village, the number of flats will be:
= 10/3 × 30
= 10 × 10
= 100 flats
Since we are told that the ratio of the number of houses to the number of flats are in the ratio 9:5 and we've gotten the number of flats as 100, then the number of houses will be:
= 9/5 × 100
= 9 × 20
= 180 houses

John, Peter and Mary shared a sum of
money in the ratio 2:4:9. John and Peter
together received $360. How much money
in all was shared?
(A) $480
(B) $540
(C) $600
(D) $900
Answer:
D
Step-by-step explanation:
Here, we want to know the total amount of money shared
Total ratio is 2 + 4 + 9 = 15
Now, John and Peter with ratios 2 and 4 equals $360
If we combine their ratios, what we have would be
6:9
Let the amount shared be x
Now, mathematically
6/15 * x = 360
6x = 15 * 360
x = (15 * 360)/6
x = $900
