Answer:
The inequality is 6x ≥ -24
The solution of this inequality is {x : x ∈ R, x ≥ -4} ⇒ [-4, ∞)
Step-by-step explanation:
In the inequality not more than means ≤In the inequality at least means ≥Let us solve the question
∵ Six times a number x means 6 × x = 6x
∵ At least means ≥
∴ Six times a number x is at least -24 is 6x ≥ -24
∴ The inequality is 6x ≥ -24
Now we will find the solution of the inequality
∵ 6x ≥ -24
→ Divide both sides by 6
∵ [tex]\frac{6x}{6}[/tex] ≥ [tex]\frac{-24}{6}[/tex]
∴ x ≥ -4
∴ The solution of this inequality is {x : x ∈ R, x ≥ -4} ⇒ [-4, ∞)
Answer:
The inequality is 6x ≥ -24
The solution is x ≥ -4
Step-by-step explanation:
To solve this you have to divide both sides by 6, so 6 ÷ 6 cancels out and -24 ÷ 6 = -4
So, the solution is x ≥ -4
How we can differentiate between direct proportion and inverse proportion?
Answer:
Please check explanations for answer
Step-by-step explanation:
Here, we want to differentiate between inverse and direct proportion
Let x and y be two quantities
If they are directly proportional;
x/y = k
x = ky
where k is proportionality constant
If inversely;
xy = k
In verbal terms;
For direct proportionality, when one value increase, the other too does so and vice versa
For inverse, when one value inverse, the other decrease
The lengths of the sides of a triangle are 3, 4, 5. Can the triangle be a right angle. Yes. No.
Answer:
Yes
Step-by-step explanation:
3 , 4 & 5 are Pythagorean Triplet numbers. When lengths of a triangle's 3 sides are Pythagorean Triplet , the triangle is a right angled triangle.
The triangle will be a right angled triangle only when the hypotenuse will have length of 5 and other 2 sides will have length of either 3 or 4.
Answer:
[tex]\boxed {\boxed {\sf Yes, \ the \ side \ lengths \ 3, \ 4, \ and \ 5\ can \ make \ a \ right \ triangle}}[/tex]
Step-by-step explanation:
If the triangle is a right triangle, then the sides will check out in the Pythagorean Theorem.
[tex]a^2+b^2=c^2[/tex]
Where a and b are the legs and c is the hypotenuse.
1. Define Sides
The legs are the 2 shorter sides and the hypotenuse is the longest.
The sides given are 3, 4 (shorter), and 5 (longest). Therefore:
[tex]a=3 \\b=4 \\c=5[/tex]
2. Check the Sides in the Theorem
Substitute the values into the theorem.
[tex](3)^2+(4)^2=(5)^2[/tex]
Solve according to PEMDAS: Parentheses, Exponents, Multiplication, Addition, and Subtraction.
Solve all of the exponents first.
(3)² = 3*3= 9 (4)²= 4*4= 16[tex]9+16=(5)^2[/tex]
(5)²= 5*5= 25[tex]9+16=25[/tex]
Add the numbers on the left side of the equation.
[tex]25=25[/tex]
This is true. 25 is equal to 25, so this triangle can be a right triangle.

Class A has 26 pupils and class B has 15 pupils.
Both classes sit the same maths test.
The mean score for class A is 33.
The mean score for both classes is 39.
What is the mean score (rounded to 1 DP) in the maths test for class B?
Answer:

Answer:
She must read more than 5 hours
Step-by-step explanation:
equation 12h+10>70
12h>60
h>5
So she must read more than 5 hours
(can I get brainliest now)
Answer:
She must read more than 5 more hoursD.12h+10=512x5=60+10=70 pages.
She reads 12 pages per hour, so if she read for 5 hours, she would have read 60 pages. She has already read 10 pages, so that would equal 70 Pages.

A Large earthworm can travel 25 centimeter in 12 seconds. How many meters does the earthworm travels in1 minute?
We know that it can travel 25 centimetres in 12 seconds. First, we break down the minute into seconds.
60/12= 5
______________________________
Now, multiply 25 by 5.
25x5=125
__________________________________
With this knowledge, we just have to convert the centimetres, to meters.

17. [tex]y=0.5x[/tex]
18. [tex]y=3x[/tex]
19. [tex]y=2x[/tex]
Step-by-step explanation:
Equation is [tex]y=kx[/tex] where k is a constant of proportionality.
16.
[tex]\frac{y}{x}=\frac{10.5}{1.5}=\frac{14}{2}=\frac{24.5}{3.5}=\frac{35}{5}=7[/tex]
So, equation is [tex]y=7x[/tex]
17.
[tex]\frac{y}{x}=\frac{1}{2}=\frac{2}{4}=\frac{2.5}{5}=\frac{3.5}{7}=\frac{1}{2}=0.5[/tex]
Equation is [tex]y=0.5x[/tex]
18.
[tex]\frac{y}{x}=\frac{6}{2}=\frac{9}{3}=\frac{15}{5}=\frac{18}{6}=3[/tex]
Equation is [tex]y=3x[/tex]
19.
[tex]\frac{y}{x}=\frac{4}{2}=\frac{8}{4}=\frac{14}{7}=\frac{18}{9}=2[/tex]
Equation is [tex]y=2x[/tex]

To get the graph, we will need to solve each inequality differently
For the first one, we have that
x/4 < -1-7
x/4 < -8
x < -8 * 4
x < -32
For the second side;
2x-1 ≥ 9
2x ≥ 10
x ≥ 5
So we have two arrows facing different directions
On the left should be unshaded while the right hand side should be shaded

Answer choice A is correct
in the following figures find the value of angle COD if angle abc is equal to 75 degree and a b is equal to CD
Angle AOB is given as 75 degrees.
O is the center of the circle so AO and CO are the same length. AB and CD are the same length, so angle COD would be the same as AOB
COD = 75 degrees.
Answer:
75°
Step-by-step explanation:
It is given that:
AB and CD are chords of the circle which are equal. Equal chords subtends equal angles at the center of the circle. [tex] \because m\angle AOB = 75\degree [/tex] [tex] \therefore m\angle COD = 75\degree [/tex]Alex helps his father milk cows on their dairy farm. They are paid $2.25
