Answer: 1/8 hours or 7.5 minutes
Step-by-step explanation:
Since Hannah spent 1/2 an hour to complete 4 math problems. We are further told that she spent an equal amount of time on each problem.
The amount of time spent on each problem will be:
= 1/2 ÷ 4
= 1/2 × 1/4
= 1/8 hours
Since 60 minutes = 1 hour
1/8 hours = 1/8 × 60 = 7.5 minutes each.

Write and solve the equation modeled below.
can someone help me ? ☝️
Seleccionamos los valores de x y y que sean soluciones de los sistemas de ecuaciones planteados x + 3 = y x2- 16y2 = 0
Responder:
Los valores de y son 3/5 y -1
Los valores de x son = -12/5 y -4
Explicación paso a paso:
Dadas las eqautions;
x + 3 = y ...... 1
x ^ 2- 16y ^ 2 = 0 ..... 2
Sustituya la ecuación 1 en 2 que tendremos;
x ^ 2- 16y ^ 2 = 0
x² - 16 (x + 3) ² = 0
x²-16 (x² + 6x + 9) = 0
x²-16x²-96x-144 = 0
-15x²-96x-144 = 0
15x² + 96x + 144 = 0
5x² + 32x + 48 = 0
Al factorizar tendremos;
5x + 12 = 0 yx + 4 = 0
x = -12/5 y -4
Obtenga los valores de y;
recuerda que y = x + 3
Si x = -12/5
y = -12/5 + 3
y = 3/5
Si x = -4
y = -4 + 3
y = -1
Por tanto, los valores de y son 3/5 y -1

Answer:
9x² + 16y² - 24xy
Step-by-step explanation:
(3x - 4y)²
⇒ (3x)² + (4y)² - 2 (3x) (4y) {(a - b)² = a² + b² - 2ab}
⇒ 3²x² + 4²y² - 2 (12xy)
⇒ 9x² + 16y² - 24xy

A small container of detergent holds 75% as much as the large container of detergent. If the small container hold 36 ounces, the large container will hold ounces.
Answer:
48 ounces
Step-by-step explanation:
Let the amount in small container be x and that of largest be y
If a small container of detergent holds 75% as much as the large container of detergent, this can be represented as;
x = 75% of y
Given x = 36
36 = 75% of y
36 = 0.75y
y = 36/0.75
y = 48 ounces
Hence the large container will hold 48 ounces

PLEASE I NEED THIS DONE BY MIDNIGHT HELP
Khalid and Jesse took different overnight trains.
The graph shows the relationship between the total distance Khalid traveled and the time in hours.
The distance Jesse traveled after x hours is given by the equation y = 150x. Who, if anyone, traveled at a faster speed?
Use the drop-down menus to explain your answer.
Khalid’s rate is ____ miles per hour. Jesse’s rate is ____ miles per hour. So, ____ train traveled at a faster speed.
Answer:
Khalid’s rate is ___140_ miles per hour. Jesse’s rate is _150___ miles per hour. So, _Jesse’s___ train traveled at a faster speed.
Step-by-step explanation:
The general equation of a straight line is
y = mx + b
for y = 150x
We have the slope as 150
This is 150 miles/hour
This relates to Jesse’s train speed
for Khalid, we have his own speed obtainable from the graph
The speed is simply the slope of the graph
We proceed to select two points from the graph and find the slope
The points are; ((1,140) and (4,560)
Mathematically, the slope will be;
m = (y2-y1)/(x2-x1)
m = (560-140)/(4-1) = 420/3 = 140 miles per hour

Answer:
A=2.5
B=2
Step-by-step explanation:
A parallelogram has to have the opposite sides equal each other. In this case side LM and side ON have to be equal.
We can compare the two sides using algebra.
4b+7=8b-1
Using simple methods, we can isolate b on a single side.
1+7=8b-4b
8=4b
b=2
From this we learn b is 2. To find out the value of A on side MN and LO, we will plug in the value for b at all instances of B in this equation.
2a = 2b+1
2a = 2(2)+1
2a=4+1
2a=5
a=2.5
A parallelogram has sides 8 ft and 14 ft the height corresponding to the 14 ft base is 4 ft what is the height corresponding to the 8 ft base
Given :
A parallelogram has sides 8 ft and 14 ft the height corresponding to the 14 ft base is 4 ft.
To Find :
The height corresponding to the 8 ft base.
Solution :
Since, both parallelogram are similar. So, ratio of the sides of parallelogram is similar in both the cases.
[tex]\dfrac{h_1}{h_2}=\dfrac{b_1}{b_2}\\\\\dfrac{8}{14}=\dfrac{h_1}{4}\\\\h_1 = \dfrac{8\times 4}{14}\\\\h_1 = 2.285 \ ft[/tex]
Therefore, the height corresponding to the 8 ft base parallelogram is 2.285 ft.
