The total drop in temperature, −20∘F, divided by 4 hours equals −5∘F per hour. The temperature dropped 5∘F each hour. (option 1)
What does the sentence mean?Division is the process of grouping a number into equal parts using another number. The sign used to denote division is ÷. Division is one of the basic mathematical operation.
If the total drop in temperature over 4 hours is −20∘F, in order to determine the temperature drop each hour, divide −20∘F by 4.
Drop each hour = −20∘F / 4 = −5∘F

slope intercept form of -5/6x+4
The slope of equation y = -5/6 x + 4 is -5/6 and the slope-intercept form of -5/6x+4 is y = -5/6 x + 4
The slope of a function y = f(x) is given by a formula
slope = y2-y1 / x2- x1
where ( x1 , y1) and (x2, y2) are coordinates of any two points on the line of graph representing y = f(x)
Or we can simply use the slope-intercept form
y = mx+ c
where m is the slope of the given equation and c is the constant
so, in the given equation y = -5/6 x + 4
slope of the equation is -5/6
Hence, The slope of equation y = -5/6 x + 4 simply is -5/6 and the slope intercept form of -5/6x+4 is y = -5/6 x + 4
When you know the slope of the line to be investigated and the point given is also the y intercept, you can utilize the slope intercept formula y = mx + b. (0, b). The y value of the y intercept point is represented by b in the formula.

If a number is greater than -500, then the number is greater than 500.
Determine the truth value of the conditional statement. Explain.
The truth value of the conditional statement is false
How to determine the truth value of the conditional statement?
The conditional statement is given as
“If a number is greater than -500, then the number is greater than 500.”
The above conditional statement is false
This is because not all numbers greater than -500 are greater than 500
for example 450 is greater than -500, but less than 500 that is the number between -500 and 500 will not satisfy the above statement.
Hence, the truth value of the conditional statement is false

a vineyard has 145 acres of chardonnay grapes. a particular soil supplement requires 5.50 g for every square meter of vineyard. how many kilograms of the soil supplement are required for the entire vineyard? (recall that 1 km2
3230 Kilograms of the soil supplement are required for the entire Vineyard.
Some units that need to be recalled are as follows:
1 km = 1000 m
1 km^2 = 1000000 m^2
1 km^2 = 247 acres
1 kg = 1000 g
Let's tackle the problem now:
A vineyard has 145 acres of Chardonnay grapes.
145 acres = [tex]\frac{145}{247}[/tex]× 1 km^2
145 acres = 145/247 km^2
145 acres ~ 0.587 km^2
A particular soil supplement requires 5.50 grams for every square meter of vineyard
1m^2 → 5.50 gram
1 km^2 = 10^6 →5.50 x 10^6 gram
1 km^2 →5.50 x 10^6 x 10^-3 kg
1 km^2 →5.50 x 10^3 kg
145 acres = 145/247 km^2 →145/247 x 5.50 x 10^3 kg
145 acres → 797500/247 kg
145 acres → 3230 kg
It required 797500/247 kg ~ 3230 kg of the soil supplement for the entire Vineyard.

Given directed line segment cd, if point e divides cd three-fourths of the way from c to d, find the coordinates of e.
The coordinates of point E is (-2, -1.5)
How to determine the coordinates of point E?
see in the file attached below
The given parameters are
C = (1, 6)
D = (-3, -4)
The ratio 3/4 can be represented as:
m : n = 3 : 1
So, the coordinate of point E is
E = 1/(m + n) * (mx2 + nx1, my2 + ny1)
So, we have:
E = 1/(3 + 1) * (3 * -3 + 1 * 1, 3 * -4 + 1 * 6)
Evaluate
E = 1/(4) * (-8, -6)

passing through (7, y) and (-1,-3) has a slope of 3/4.
Answer: y=3
Step-by-step explanation:
Slope formula: m=(y2-y1)/(x2-x1)
3/4=(y2-y)/(x2-x1)
3/4=(-3-y)/(-1-7)
3/4=(-3-y)/(-8)
(3/4=(-3-y)/(-8))*(-1) ==> Negate the equation to remove the negative denominator
-3/4=(-3-y)/8
8*(-3/4)=(-3-y)/8 * 8
8*(-3/4)=(-3-y)/8 * 8

Levi must score 220 in Exam B in order to do equivalently well as he did in Exam A
How well must Levi score on Exam B in order to do equivalently well as he did on Exam A?The given parameters are:
Exam A
Score = 710
Mean = 700
Standard deviation = 25
Exam B
Mean = 200
Standard deviation = 50
The z-score is calculated as
z = (Score - Mean)/Standard deviation
For exam A, we have
z = (710 - 700)/25
z = 0.4
For exam B, we have
z = (Score - 200)/50
Substitute z = 0.4 in z = (Score - 200)/50
0.4 = (Score - 200)/50
This gives
Score - 200 = 20
Add 200 to both sides
Score = 220
Hence, Levi must score 220 in Exam B in order to do equivalently well as he did in Exam A

What is the measure of ∠ADB? WILL CHOOSE THE BRAINLIEST ANSWER!

Because the triangle BAC is an isosoles angle BCA and ABC must be the same so 48
We can now use the angle on a straight line rule to figure out angle DBA 180-48=132
We know that triangle DBA is an isosoles trianlge so and x and DAB must be the same and both be x, and we know that angles in a triangle add up to 180 so the equation can be written as:
