Answer:
70%
Step-by-step explanation:
Given that:
Initial water level in the tank at noon = 10 cm
After several hours, water level = 3 cm
To find the percentage change in the water in the tank, we can use the following formula:
[tex]Percentage\ Change = \dfrac{Final\ Value - Initial\ Value }{Initial\ Value}\times 100[/tex]
Here, Final Value = 3 cm
Initial Value = 10 cm
Putting the values in the formula:
[tex]Percentage\ Change = \dfrac{3 - 10 }{10}\times 100\\\Rightarrow Percentage\ Change = -70\%[/tex]
Here, negative value, means there is a decrease in the final value from the initial value.
Therefore, the answer is 70% decrease.
Evaluate the function at the indicated value.

Dante wrote several equations and determined that only one of the equations has infinitely many solutions. Which of these equations has infinitely many solutions?
6 (x + 3) + x = 7 x + 2 + 1
6 (x + 3) + x = 7 x + 5
6 (x + 3) + x = 6 x + 3 + 15
6 (x + 3) + x = 7 x + 9 + 9
9514 1404 393
Answer:
6 (x + 3) + x = 7 x + 9 + 9
Step-by-step explanation:
The equation will have an infinite number of solutions if the left side is equal to the right side. The left side in each case is 7x+18.
The right sides are (in the order shown) ...
= 7x +3
= 7x +5
= 6x +18
= 7x +18 . . . . . . matches the left side
The equation 6 (x + 3) + x = 7 x + 9 + 9 will have infinitely many solutions.
You can represent the measures of an angle and its complement as x° and (90 − x)°. Similarly, you can represent the measures of an angle and its supplement as x° and (180 − x)°. Use these expressions to find the measures of the angles described. The measure of an angle increased by 62° is equal to the measure of its complement
The measure of the angle is 14 degrees and the measure of its complement is 76 degrees
3. A study team is discussing multiplying integers.
Scott says, "Two negatives multiply to make a negative and two positives multiply to make a positive."
Aaron says, "No, it depends on what there are more of', like -10(3) is negative, but 5(-2) is positive."
Zachary says, "If the signs are the same it is positive, but if they signs are different, the product is
negative."
Tina disagrees. "The sign of the product is the sign of the first number being multiplied."
Who, if anyone, is correct? Give at least three examples to illustrate the concept these students are
debating.
Answer:

i need help with multiplying decimals i ust dont get it i also need help with dividing decimals
Answer:
To multiply decimals, first multiply as if there is no decimal. Next, count the number of digits after the decimal in each factor. Finally, put the same number of digits behind the decimal in the product.
To divide a decimal by another decimal: Move the decimal point in the divisor to the right until it is a whole number. Move the decimal point in the dividend to the right by the same number of places as the decimal point was moved to make the divisor a whole number. Then divide the new dividend by the new divisor.
Answer:
Step-by-step explanation:
Okay, first multiplying decimals:
If you want to multiply decimals first you have to put the 2 decimals one on top of each other
for example:
2.27
x 4.89
Then multiply it just like if you were multiplying a regular number without the decimals
227
x 489
This equals 111,003 now to figure out the answer we can count that there are 4 numbers after the decimal point so you move the decimal point 4 to the left so the answer would be 11.1003
8x-2=-9+7x plz answer quick brainiest to who gets it first.
Answer:
x=-7
Step-by-step explanation:
8x-2=-9+7x
8x=-7+7x
1x=-7
x=-7
Answer: x=-7
Step-by-step explanation: add 2 to both sides
8x=-7+7x
subtract 7x from both sides
x=-7
Check it 8(-7)-2=-9+7(-7)
8(-7)=-56
-56-2=-58
9+7(-7)
7(-7)=-49
-49+-9= -58
It checks out hope this helps ^_^
Zach is playing a video game. A penalty in Jupiter Battle is loss of 7 power points. Zach lost a total of 49 power points. How many times was Zach penalized
Answer:
Number of penalties= 7
Step-by-step explanation:
Giving the following information:
A penalty in Jupiter Battle is a loss of 7 power points. Zach lost a total of 49 power points.
To calculate the number of penalties, we need to use the following formula:
Number of penalties= total point lost / 7
Number of penalties= 49/7
Number of penalties= 7
A line with a slope of -1 passes through the point (-4, 6). What is its equation in point-slope form
Answer:
The equation would be y-6= -1(x+4)
Step-by-step explanation:
point slope form is y-y1=m(x-x1)
substitute y-6= -1(x-(-4)
simplify y-6= -1(x+4)

Juan is rewriting the expression 12 d minus 26 c as a product. Which statements about the expression are accurate and relevant to his rewriting the expression? Select two options.
Complete question :
Juan is rewriting the expression 12 d minus 26 c as a product. Which statements about the expression are accurate and relevant to his rewriting the expression? Select two options. The GCF of the numbers in each term in the expression is 2. The GCF of the numbers in each term in the expression is 4. The GCF of the variables in each term in the expression is cd. The factored expression is 2 (6 d minus 13 c). The factored expression is 2 c d (6 minus 13).
Answer:
The GCF of the numbers in each term in the expression is 2.
The factored expression is 2 (6 d minus 13 c).
Step-by-step explanation:
The two numbers being written are :
12d ; - 26c
Then greatest common factor of the Coefficients is :
Factors of
12 : 1, 2, 3, 4, 6, 12
26 : 1, 2, 13
Hence, the greatest common factor is 2.
Expressing 12d and - 26c as a product :
12d * - 26c
Factorizing :
2(6d - 13c)

Suraj took a slice of pizza from the freezer and put it in the oven. The oven heated the pizza at a rate of 7.5^\circ7.5 ∘ 7, point, 5, degrees Celsius per minute, and it reached the desired temperature of 80^\circ80 ∘ 80, degrees Celsius after 121212 minutes.
Answer:
y = 7.5t - 10
Step-by-step explanation:
A linear equation is in the form y = mx + b, where y is a dependent variable, x is an independent variable, m is the rate of change and b is the value of y when x = 0.
Let y represent the temperature of the pizza and t represent the time the pizza spent in the freezer in minutes. Therefore:
y = mt + b
Since the oven heats the pizza at a rate of 7.5°C, therefore
y = 7.5t + b (we need to find b)
It takes 12 minute (t = 12) to reach a temperature of 80°C (y = 80), hence:
80 = 7.5(12) + b
80 = 90 + b
b = -10
This means that the initial temperature of the pizza when removed from the freezer is -10°C. The linear equation is:
y = 7.5t - 10
