Answer:
7≥t
Step-by-step explanation:
The tank already has 13litres of water in it.
Keisha plans on increasing the quantity of the water to 41 litres. Hence,
41 litres - 13litres = 28litres
The above implies that she needed 28litres to be added to the fish tank.
She adds 4 litres per minute
Now, the question can now be reframed as how many minutes will be needed to add 28litre.
Considering to proportion method
4litres = 1 minute
28litres = t minutes
4litres × t minutes = 28litres
t = 28/4
t = 7 minutes
Hence, at least 7 minutes will be needed to increase the quantity of the tank water from 13litres to 41litres
But since we are to write the answer in an inequality form.
41≥ 13+4t
Solve for t
41≥13+4t
41-13≥4t
28≥4t
Divide both sides by 4
28/4≥4t/4
7≥t
Round 324,145

hundred thousand.
Answer:
320,145
Step-by-step explanation:
Anything under 5 goes down and anything above 5 goes up.
Answer:
300,000
Step-by-step explanation:
Given the following question:
[tex]324145[/tex]
To round to the nearest hundred thousand of this number we must first find the hundred thousand place value and then determine if the number next to that place value is greater than five, if so, we can round the number up.
[tex]324145[/tex]
[tex]PV=3[/tex]
[tex]2 < 5[/tex]
[tex]=30000[/tex]
Rounded to the nearest hundred thousand "300,000" is your answer.
Hope this helps.

Answer:
The rule is "Subtract 9"
n = 11
Step-by-step explanation:
To find the rule you have to find what's common with all of them. This requires a little bit of testing.

Do I divide by 10? No because it doesn't work for all of them.
Do I divide by 4? No because it doesn't work for all of them.
Do I subtract by 9? Yes because it works for all of them.
Rules can be a lot of things. Subtraction, multipilcation, division, addition, or with variables.

Answer:
We can show that ∆ABC is congruent to ∆A′B′C′ by a translation of (x-2, y) unit(s) and a across the x-axis.
Step-by-step explanation:
The triangle ABC is shown in the image attached. The coordinates of the triangle are A(8, 8), B(10, 4), C(2, 6), while the triangle A'B'C' is at A'(6, -8), B'(8, -4), C'(0, -6).
A transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, translation, dilation and rotation.
If a point O(x, y) is translated a units on the x axis and b units on the y axis, the new coordinate is O'(x+a, y+b).
If a point O(x, y) is reflected across the x axis, the new coordinate is O'(x, -y)
Hence if triangle ABC is translated -2 units on the x axis (2 units left), the new coordinates are A*(6, 8), B*(8, 4), C*(0, 6). If a reflection across the x axis is then done, the new coordinates are A'(6, -8), B'(8, -4), C'(0, -6).
Answer:
We can show that ∆ABC is congruent to ∆A′B′C′ by a translation of 2unit(s) left and reflected across the x-axis.

what describes an equation that has a solution set of "all real numbers"
Answer:
Any value you choose for x will make the equation a TRUE statement. This type of equation is called an identity, and the solution set is all real numbers.
An identity is an equation that, regardless of the values used, is always true.
What is the solution to the equation?The distribution of weights to the variables involved that establishes the equilibrium in the calculation is referred to as a result.
An identity is an equation that, regardless of the values used, is always true.
For the linear equation y = mx + c, all the values of the variable x are real numbers because the quadratic function is defined.
For the quadratic equation y = (x - h)² + k, all the values of the variable x are real numbers because the quadratic function is defined.

6x-16 = -19 Combine like terms
6x = -3 Add
x = -1/2 Division
Answer: x=-1/2 in decimal form -0.500
Step-by-step explanation: Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
3*(2*x-7)+5-(-19)=0
3 • (2x - 7) + 5) - -19 = 0
Pull out like factors :
6x + 3 = 3 • (2x + 1)
Solve : 2x+1 = 0
Subtract 1 from both sides of the equation :
2x = -1
Divide both sides of the equation by 2:
x = -1/2 = -0.500

Answer:
each child will get 2 1/3 quarts of juice each
Step-by-step explanation:
Question 7
Total amount of juice = 1 4/6 + 2 + 2 + 2 + 2 2/6 + 2 5/6 + 2 5/6 + 3 = 56/3
Number of children = 8
If the juice was shared equally: 56/3 ÷ 8 = 7/3 = 2 1/3 each
Therefore, each child will get 2 1/3 quarts of juice each

Tiana placed two orders for flowers and bushes. The first order was for 24 flowers and 6 bushes. The total cost of the first order was $144. The second order was for 18 flowers and 3 bushes. The total cost of the second order was $90. What is the cost of each plant?
Answer:
Step-by-step explanation:
24x + 6y = 144.
18x + 3y = 90.
Divide the (24x + 6y = 144) by 3.
8x + 3y = 48.
18x + 3y = 90.
Cancel the 3y.
8-18x = -10x.
48-90 = -42.
-10x = -42.
x = 4.2
8(4.2) + 3y = 48.
33.6 + 3y = 48.
Cancel out the whole number.
3y = 14.4
y = 4.2
The cost of a flower is $3 and a bush is $12.
What is the system of equations?One or many equations having the same number of unknowns that can be solved simultaneously are called simultaneous equations. And the simultaneous equation is the system of equations.
Given:
Tiana placed two orders for flowers and bushes.
The first order was for 24 flowers and 6 bushes.
The total cost of the first order was $144.
The second order was for 18 flowers and 3 bushes.
The total cost of the second order was $90.
Let x be the number of flowers and y be the number of bushes.
So, we have a system of equations,
24x + 6y = 144
18x + 3y = 90
Simplifying,
4x + y = 24
6x + y = 30
Subtracting the equations,
we get,
2x = 6
x = 3, and y = 12
Therefore, the solution is x = 3, and y = 12.

Answer:
The third one x+49+28=180
Step-by-step explanation:
We can say that the angle between the 29° angle and the 49° angle is equal to x, since they are vertically opposite angles.
The sum of 28+49+x is equal to a supplement angle which is a straight line essentially
We can then say x+28+49=180

Which of the following are lengths of the sides of a 30°-60°-90° triangle? A. 5√3, 15., 10√3 units B. 3, 4, and 5 units C. √3, 3√3 and 2√3 units D. 5√6, 12√6, and 13√6 units
Answer:
A
Step-by-step explanation:
law of sine
c/sin(C) = b/sin(B) = a/sin(A)
with the sides and corresponding angles being always opposite.
sin(90) = 1
sin(30) = 0.5
c, the Hypotenuse, is the longest side in such a right-angled triangle.
c/1 = b/0.5
b = c×0.5 = c/2
so, one side has to be half the length of the longest side (Hypotenuse).
the only answer meeting that criteria is A.
the longest side is 10×sqrt(3) = 17.32...
the side half of that is 5×sqrt(3).
and Pythagoras for such a triangle is then
c² = (c/2)² + a²
c² = c²/4 + a²
so, a² = 3c²/4
c² = c²/4 + 3c²/4
therefore we can check also the third side
15² = 3×(5×sqrt(3))² = 3×25×3 = 3×75 = 225 = 15²
correct.
A is such a triangle.
