The equation that can be used to determine when each cooler would contain the same amount of water is 2.5 = 0.75t.
When the coolers would have the same amount of water?Equation that can be used to determine the amount of water in the first cooler at time t : 4.5 + 0.1t
Equation that can be used to determine the amount of water in the second cooler at time t : 7 + 0.25t
Where t represents seconds
When they have the same amount of water, the two above equations would be equal
4.5 + 0.1t = 7 + 0.25t
Combine similar terms
7 - 4.5 = 0.1t - 0.25t
2.5 = 0.75t

Marshall has $700 in an account that earns 13% interest compounded annually.
To the nearest cent, how much interest will he earn in 1 year?
Marshall has $700 in an account that earns 13% interest compounded annually. At the end of one year Marshall will have the sum of $791.
How to calculate simple interest amount?If the initial amount (also called as principal amount) is P, and the interest rate is R% annually, and it is left for T years for that simple interest.
then the interest amount earned is given by:
[tex]I = \dfrac{P \times R \times T}{100}[/tex]
The principal amount (P)= $700
The interest rate(R) = 13%
The period of investment (T) = 1 year
Simple interest
= P×T×R/100
= 700×T×13/100
= 9100/100
= $91
Therefore, the total amount she will receive at the end of a year
= 700 + 91
= $791

Find the value of x. If necessary, round your answer to the nearest tenth. The figures are not drawn to scale.
The value of the variable 'x' in the circle will be 26.7 units. Then the correct option is D.
What is a circle?It is the close curve of an equidistant point drawn from the center. The radius of a circle is the distance between the center and the circumference.
In primary mathematics, a statement defines a relationship between the four line segments formed by two crossing chords within a circle.
The equation is form by the above theorem is written as,
9 · x = 24 · 10
Simplify the equation, then we have
9 · x = 24 · 10

The original blueprint for the Morenos living
room has a scale of 2 inches
5 feet, The family
wants TO use a new blueprint that shows the
length of the living room to be 15 inches. If
the width of the living room on the original
blueprint is 6 inches and the length is 9.6 inches,
what are the scale and the width of the new
blueprint?
Answer:
new width=9.375 in
new scale= 1 foot= 0.4 inches
Step-by-step explanation:
Firstly to find the width we can set up a proportion:
[tex]\frac{x}{15}[/tex] =[tex]\frac{6}{9.6}[/tex], after solving for x, x= 9.375, which gives us our width.
To find the new scale, we knew that the old scale was 2 in=5 feet, or 1 in=2.5 feet, so to find the new one we can also set a new proportion,
[tex]\frac{1}{2.5} = \frac{15}{x}[/tex]
After solving you will get x= 37.5, so 15 inches= 37.5 feet, but to simplify we can divide,
15/37.5= 0.4

Find the value of X
Find the measures of the following angles
Answer:
angle X = 80; angle Y = 100; angle W = 100; x = 10
Step-by-step explanation:
opposite angles are always equal, which means that angle Z and angle X are equal.
angle X = 80º
now, angle Z plus angle Y makes a straight line, which means 180º (if you put the two angles next to each other)
that means 80 + (11x - 10) = 180
11x = 110
x= 10
by using this, we can find angles Y and W since opposites are equal
11x - 10 would be 100 and angles Y and W would be 100

5² + b² = 7²25 + b² = 49b² = 49 - 25b² = 24b = √24b = 2√6Answer:
2√6 unitsStep-by-step explanation:
The length of the third side can be determined using pythogoras theorem. Keep in mind that pythogoras theorem can only be used when finding the missing side length of a right triangle.
[tex]\text{Pythagoras theorem: (Longest side})^{2} = (\text{Leg of right triangle}_{1} ) ^{2} + (\text{Leg of right triangle}_{2} )^{2}[/tex]
In this triangle, we are given that:
The longest side of the triangle is measuring 7 units. A leg of the triangle is measuring 5 unitsSubstitute the measures into the pythogoras theorem:
[tex](7})^{2} = (5 ) ^{2} + (\text{Leg of right triangle}_{2} )^{2}[/tex]
Simplify both sides of the equation:
[tex]\rightarrowtail (7 \times 7}) = (5 \times 5) + (\text{Leg of right triangle}_{2} )^{2}[/tex]
[tex]\rightarrowtail49 = 25 + (\text{Leg of right triangle}_{2} )^{2}[/tex]
Subtract 25 both sides:
[tex]\rightarrowtail49 - 25 = 25 - 25 +(\text{Leg of right triangle}_{2} )^{2}[/tex]
[tex]\rightarrowtail24 = (\text{Leg of right triangle}_{2} )^{2}[/tex]
Square root both sides and simplify:
[tex]\rightarrowtail\sqrt{24} = \sqrt{(\text{Leg of right triangle}_{2} )^{2}}[/tex]
[tex]\rightarrowtail\sqrt{3 \times 2\times 2 \times 2} = \sqrt{(\text{Leg of right triangle}_{2} )^{2}}[/tex]
[tex]\rightarrowtail2\sqrt{3 \tim \times 2} = \text{Leg of right triangle}_{2}[/tex]

Using an arithmetic sequence, it is found that 89 dots would be found in the 30th step.
What is an arithmetic sequence?In an arithmetic sequence, the difference between consecutive terms is always the same, called common difference d.
The nth term of an arithmetic sequence is given by:
[tex]a_n = a_1 + (n - 1)d[/tex]
Researching the problem on the internet, it is found that the first step has 2 dots, the second has 5 dots, the third has 8 and so on, hence the first term is [tex]a_1 = 2[/tex] and the common difference is d = 3.
Then, the number of dots in the nth step is given by:
[tex]a_n = 2 + 3(n - 1)[/tex]
In the 30th step, the number will be given by:
[tex]a_{30} = 2 + 3(30 - 1) = 89[/tex]
