Answer:
25 minutes
Step-by-step explanation:
let x represent total time when both containers to have the same amount of water.
the equation to represent container A = 200 + 6x
the equation to represent container B = 500 - 6x
Because both containers would have the same amount of water, the two equations would be equal to each other
200 + 6x = 500 - 6x
collect like terms
12x = 300
x = 300/12
x = 25 minutes
I WILL MARK BRAINLIEST! A parabola opening up or down has vertex (0,3) and passes through (4,7). Write its equation in vertex form.
Ok...so we have this........
y = ax2 + 4 ....... and we need to find "a"
So we have
-1 = a(-10)2 + 4
-5 = a (100)
(-1/20) = a ....... So we have ..........
y = (-1/20)(x- 0)2 + 4 or just (-1/20)x2 + 4
Note that this parabola opens downward...That makes sense since the vertex is above the x axis and the parabola passes through a point below the x axis.
Hope This Helped!

__x+6 = 2(-3x + 1) + x - 16
Answer:
-5
Step-by-step explanation:
-5x+6 = 2(-3x + 1) + x - 16
-5x+6 = -6x + 2 + x - 16
-5x+6 = -5x -14
+6≠-14⇒x∈Ф

Answer:
x = 70°, y = 110° , z = 85°
Step-by-step explanation:
∠ BEA and ∠ CDA are corresponding angles and congruent , then
x = 70°
x and y are adjacent angles and sum to 180°
x + y = 180°
70° + y = 180° ( subtract 70° from both sides )
y = 110°
∠ ABE and ∠ ACD are corresponding angles and congruent , then
z = 85°
given a is equal to 60 degree and 30 degree prove that sin a + b is equal to sin a cos b + cos a sin b
Answer:
A = 60 and B = 30
Now, A + B = 60 + 30 = 90
Also, A – B = 60 – 30 = 30
sin (A + B) = sin 90 = 1
sin A cos B + cos A sin B = sin 60 cos 30 + cos 60 sin 30
An individual head of sprinkling water system covers a circular area of grass with a radius of 25 ft the yard has three sprinkler heads the each cover a circular area with no overlap. What is the approximate total area that will be watered
Answer:
Answer will be 5890 square feet. Step-by-step explanation: An individual head of a sprinkler system covers a circular area of grass with a radius of 25 feet. Now 3A = 3×π×625 feet²= 3×3.14×625 = 5887.5 ≈ 5890 square feet.

A city has a higher elevation than Coachella, CA. Select all numbers that could represent the city's elevation. Be prepared to explain your reasoning.
Complete question :
A city has a higher elevation than Coachella, CA.
Coachella's elevation is 22 feet below sea level (-22 ft.)
Select the four numbers that could represent the city’s elevation. Be prepared to explain your reasoning.
Group of answer choices
-11 feet
4 feet
-8 feet
-35 feet
0 feet
-44 feet
Answer:
- 11 feets
4 feets
0 feets
-8 feets
Step-by-step explanation:
Kindly note, that, elevation below sea level should be represented with negative Integers:
Coachella's elevation = - 22 feets
SINCE it is a stated that city A has a higher elevation than Coachella ;
Therefore, Elevation of city A is greater than - 22 feets
Therefore x from the options possible elevation of city A are :
All values in the option greater than - 22; The numbers include :
-8 feets, 0 feets, - 11 fees, 4 feets

Find the gradient of the line passing through the points (4a,-a) and (6a,5a)
Answer:
The gradient of the line passing through the points (4·a, -a) and (6·a, 5·a) is 3
Step-by-step explanation:
The gradient of a (straight) line given the 'x' and 'y' coordinates of two points on the line, (x₁, y₁), and (x₂, y₂) can be found using the following formula;
[tex]The \ gradient \ of \ a \ line, \, m =\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
The coordinates of two points on the given line are;
(4·a, -a), and (6·a, 5·a)
Therefore, we get;
[tex]The \ gradient \ of \ the \ line =\dfrac{5\cdot a-(-a)}{6 \cdot a-4 \cdot a} = \dfrac{6\cdot a}{2 \cdot a} = 3[/tex]
The gradient of the line = 3.
Em um campeonato de futesal igor cobrou 20nfaltas das quais 65% foram convertidos em gol quantos gols de falta ele marcou nesse camponato
Responder:
13 gols
Explicação passo a passo:
Dado que :
Taxa de conversão = 65%
Número de fotos tiradas = 20
O número estimado de gols marcados será:
O produto da taxa de conversão e o número de fotos tiradas;
Número de fotos tiradas * taxa de conversão
20 * 65%
20 * 0,65
= 13 gols
Portanto, número estimado de gols marcados = 13 gols

Justin has a savings account.
• He started with $70 in his account.
• He deposits $15 into the account each week.
What is the total amount Justin will have in his account after 10 weeks?
Answer:
220
Step-by-step explanation:
Multiply 15 times 10 =150
150+70=220
Hope this helps :)
==========================================================
Explanation:
After 10 weeks, he'll deposit a total of 15*10 = 150 dollars on top of the $70 already in the account. This means the grand total is 150+70 = 220 dollars
If you need to use algebra, then an algebraic expression you can use is 70+15x where x is the number of weeks. Replace x with 10 and you'll end up with 70+15*10 = 70+150 = 220. It's effectively the same idea and steps as the previous paragraph, but now we're involving a variable.

15 similar blouses and 2 similar skirts cost $505. 5 such blouses and 2 such
skirts cost $215. How much do 5 such blouses cost? need this ans asap!
Answer:
Cost of five blouses = $145
Step-by-step explanation:
Let
x = cost of blouse
y = cost of skirt
15x + 2y = 505 (1)
5x + 2y = 215 (2)
Subtract (2) from (1) to eliminate y
15x - 5x = 505 - 215
10x = 290
x = 290/10
x = 29
Substitute x = 29 into (2)
5x + 2y = 215 (2)
5(29) + 2y = 215
145 + 2y = 215
2y = 215 - 145
2y = 70
y = 70/2
y = 35
x = cost of blouse = $29
y = cost of skirt = $35
How much do 5 such blouses cost?
cost of a blouse = $29
Cost of five blouses = $29 × 5
= $145
Cost of five blouses = $145

Answer:
ΔLMN ≅ ΔLQP by (SAA)
Step-by-step explanation:
It is given that line (NM) is congruent to the line (PQ), meaning they have the same measure. This is signified by the small red line on each of these sides.
Moreover, it is also given that angle (MNL) is congruent to angle (QPL), this is shown by the red arc around these angles.
Finally one can figure out that angle (NLM) is congruent to angle (PLQ) by the vertical angles theorem. The verticle angles theorem states that when two lines intersect, the opposite angles are congruent.
Thus the two triangles are congruent by side-angle-angle postulate, abbreviated as (SAA).
A truck that can carry no more than 7600 lb is being used to transport refrigerators and upright pianos each refrigerator weighs 250lb and each piano weighs 425 lb. Write and graph an inequality to show how many refrigerators and how many pianos the truck could carry. Will 13 refrigerators and 11 pianos overload the truck? Explain.
Answer:
Step-by-step explanation:
7600 ≥ 250r+425p
7600 ≥ 250(13)+425(11)
7600 ≥ 3,250+4675
7600≥7925
This statement is incorrect. Therefore no, the truck cannot transport that load
