The ongoing profundity of the hole is less than the negative region feet subterranean level. Then the right choice is D.
What is inequality?Inequality is defined as an equation that does not contain an equal sign. Inequality is a term that describes a statement's relative size and can be used to compare these two claims.
A hole needs to arrive at no less than 72 feet subterranean level. This implies it should be multiple 1/2 times its ongoing profundity. This profundity is addressed by the imbalance 4 ¹/₂ d < - 72, where d is the ongoing profundity of the burrow.
4 ¹/₂ d < - 72
Simplify the inequality, then we have
4 ¹/₂ d < - 72
4.5d < - 72
d < - 72 / 4.5
d < - 16
The ongoing profundity of the hole is less than the negative region feet subterranean level. Then the right choice is D.

Which ordered pair would form a proportional relationship with the point graphed below?
Answers
Answer:
-10, 20 because -20, 40 divided by 2 = -10, 20
The ordered pair that would form a proportional relationship with the point (-20, 40) is given as follows:
(15, -30).
What is a proportional relationship?A proportional relationship is a relationship in which a constant ratio between the output variable and the input variable exists.
The equation that defines the proportional relationship is a linear function with slope k and intercept zero presented as follows:
y = kx.
The slope k is the constant of proportionality, representing the increase or decrease in the output variable y when the constant variable x is increased by one.
The constant for this problem is given as follows:
k = 40/-20
k = -2.
Hence the equation is:
y = -2x.
When x = 15, the numeric value of the equation is given as follows:
y = -2(15)
y = -30.
Hence the point is:
(15, -30).

[[Please Explain]] The equation y - 2/3 = -2 (x - 1/4) is written in point-slope form. What is the equation in slope-intercept form? ³
O y = -2x - 1/6
O y = -2x + 7/6
O y = -2x + 5/12
O y = -2x - 11/12
Answers
y - 2/3 = -2 (x - 1/4)
First you distribute the -2 because it is the first order of operation
y - 2/3 = -2x + 1/2
Then you add 2/3 on both sides because we want to isolate y
y = -2x + 1/2 + 2/3
Then we combine like terms
y = -2x + 7/6

The total change in the outdoor temperature over 6 hours was -21°F
What was the mean change in temperature per hour?
₋₋₋₋₋₋₋₋ °F per hour
Answers
Answer:
-3.5
Step-by-step explanation:
As there was a total change of -21, that would be the first part of your equation:
-21
As 6 hours had passed and you are trying to find the mean, your equation would now be:
-21 ÷ 6 = ?
Now you can solve the equation, and the answer is -3.5°F per hour.
The mean change in temperature per hour is -3.5 °F.
what is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
The total change in the outdoor temperature over 6 hours was -21°F
So, in one hour the mean change in temperature
= -21/6
= -3.5 °F
Hence, the mean change in temperature per hour is -3.5 °F.

Solve for x
3/5 (x − 7/10)= −3 1/4
Enter your answer as a mixed number in simplest form.
Answers
Answer:
x = 11(13/14)
Step-by-step explanation:
3/5(x – 7/10) = -31/4
open the bracket:
3/5 * x – 7/10 = -31/4
3/5 * –7x/10 = -31/4
3/5 + 31/4 = 7x/10
(12+155)/20 = 7x/10
167/20 = 7x/10
cross multiply:
140x = 1670
x =1670/140
x = 11(130/140)
x = 11(13/14)
The value of x is 1/5.
What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given:
3/5 (x − 7/10)= −3 1/4
Now, Solving for x
3/5 ( x- 7/10 )= 13/4
x- 7/10 = -13/4 x 5/3
x- 7/10 = -65 /12
x= -65/12 + 7/10
x= 24/ 120
x= 1/5
hence, the value of x is 1/5.
