Answer:
Using the information given, we can use the point-slope form:
y - y1 = m(x - x1)
y - 7 = -1(x + 3)
y - 7 = -x - 3
+7 +7
y = -x + 4, this is slope-intercept form
x + y = 4, this is standard form
For the last 4.5 hours, the temperature has decreased at a rate of 2.8 Degrees Fahrenheit per hour. Which best represents the overall change in temperature over this time period?
Answer:
The overall change in temperature over the time period ∆T = -12.6°F
Step-by-step explanation:
Rate of change of temperature r = -2.8°F per hour
Time t = 4.5 hours
The overall change in temperature ∆T = Rate of change of temperature × time period
∆T = r × t
∆T = -2.8°F per hour × 4.5 hours
∆T = -12.6°F
The overall change in temperature over the time period is -12.6°F
Answer: -12.6

Juan had 4 more baseball cards and Kim. Larry has 2 more baseball cards than Juan. Altogether they have 100 baseball cards. How many baseball cards does each person have?
Answer:
Juan:34
Kim:30
Larry:36
Step-by-step explanation:
Answer:
Kim = 30
Juan = 34
Larry = 36
Step-by-step explanation:
30+34+36=100
if Kim has 30 cards and Juan has 4 more than her while Larry has 6 more then Juan would have 34 and Larry would have 36 making this equation true.

“Jackson buys a cherry snow cone on a hot day. What is the volume of “snow” he gets to eat? Use 3.14 for pi. Round you answer to the nearest tenth.”
Answer:
Correct option: Second one -> 141.3 cm3
Step-by-step explanation:
The volume of "snow" is the sum of the half sphere volume and the cone volume.
The volume of the half-sphere is given by the formula:
V = (2/3) * pi * radius^3
If the half sphere has a radius of 3 cm, we have that:
V1 = (2/3) * pi * 3^3 = 56.5 cm3
The volume of the cone is given by:
V = (1/3) * pi * radius^2 * height
If the radius is 3 cm and the height is 9 cm, we have:
V2 = (1/3) * pi * 3^2 * 9 = 84.8 cm3
So the final volume is:
V = V1 + V2 = 56.5 + 84.8 = 141.3 cm3
Correct option: Second one

Which linear equation represents a line with a slope of 9/4 and a y-intercept of 0? plz help giving out brainliest
Answer:
y = 9/4x.
Step-by-step explanation:
According to slope-intercept form, y = mx + b where m is the slope and b is the y-intercept.
So, y = 9/4x + 0
y = 9/4x.
Hope this helps!
The required equation of the line is given as 9/4x with a slope of 9/4 and a y-intercept of 0.
Given that,
The linear equation represents a line with a slope of 9/4 and a y-intercept of 0 is to be determined.
What is the slope of the line?
The slope of the line is a tangent angle made by line with horizontal. i.e. m =tanx where x in degrees.
here,
Standard equation of the line,
y = mx + c
Put , = 9/4 and c = 0
y = 9/4x + 0
y = 9/4x
Thus, the required equation of the line is given as 9/4x.

What is the measure of
Answer & Step-by-step explanation:
The problem tells us that ΔABC ≅ ΔDEF. Since we know that this is true, then we also know that ∠A ≅ ∠D, ∠B ≅ ∠E, and ∠C ≅ ∠F.
So, since we are looking for the measurement of ∠F, then all we have to do is know the measurements of ∠C because they are congruent angles.
So, the measurement of ∠F is 63°

The points (-1,4) and (2,-3) are adjacent vertices of a square. What is the area of the square? PLEASE HELP ILL GIVE BRAINLIEST
Answer:
137 units^2.
Step-by-step explanation:
A and B are positioned according to their coordinates, in the X and Y axes Imagine a right angled triangle, where the actual distance between the two points is the hypotenuse, and the other two sides are the distances in the “X” and “Y” axes that separate the two points.
In the “X” axis, they’re separated by 3 -(-1) units that’s 4…
In the “Y” axis, they’re separated by 4 - (-7) units that’s 11…
Now we have the lengths of two sides of the triangle, we can calculate the length of the hypotenuse… But why would we? we’ve been asked for the area of the square, and adding the areas of the squares on the other two sides gives our answer-
4^2 + 11^ 2 = 16 + 121, = 137 units^2. You didn’t specify units, so we don’t know what the area is, we just have a numerical value.
Answer:

Marly needs to score 586 points in order to pass a test. Every question is worth 4 points. She already has 58 points. How many more questions does she need in order to pass this test?
Answer:
89
Step-by-step explanation:
586 divide by 4 is 146.5 so then i rounded to make it 147 then subtracted the points she already had (58) which led me to 89
Answer:
132 questions
Step-by-step explanation:
First, let’s find how many more points she needs.
To find this, find the difference between the points she needs and the points she has.
points needed- points gained
She needs 586 points and already has 58 points.
586 points-58 points
528 points
Now, we need to find how many questions she needs to answer correctly.
She needs 528 points and every correct question is worth 4 points.
Therefore, we can divide 528 by 4 to find how many questions she must answer correctly.
528/4=132

Sarah has some large, polygon-shaped cardboard cutouts that she needs to sort, because she wants to hang them in her geometry classroom. The first division she needs to make is to divide the regular polygons from the irregular ones. In order to save time measuring all angles and sides of each polygon, and owing to the size and number of sides/angles in each shape, Sarah decides to measure just one angle in each polygon. Consider the following angle measures for polygons A through T, and answer the following questions.
a. If each angle measure represented an exterior measure of its polygon, which of the polygons could be regular? Explain your answers.
b. If each angle measure represented an exterior measure of a regular polygon, name each polygon by using its number of sides. (For any figure with more than 12 sides, just use the number: e.g. 45-gon.)
c. If each angle measure represented an interior measure of its polygon, which of the polygons could be regular? Explain your answers.
d. If each angle measure represented an interior measure of its polygon, which of the polygons do we know are convex? Explain your answers.

a. ABCDEFHILO
b. 36- 24- 18- dodeca- nona- octa- hexa- penta- square, triangle
c. HLNOPQ

Answer: D
Step-by-step explanation:
Distributive Property is when you want to apply to FOIL method when you are multiplying out the expression. You would have multiple number/terms to multiply out to. The only answer choice that shows this is D.
In D, you are distributing the 5 to 8 and -2. So, you are multiplying 5×8=40 and 5×-2=-10. Then you have 40-10.
A is just multiplying, 5 and 1/5.
B is just multiplying 5 and 1.
C is just Associative Property, changing the parenthesis.
D shows Distributive Property.
Answer:
The answer is DExplanation:
D is the answer because you need the 5 to be next to the number in parenthesis.C is the not the answer because when there is a minus sign with a number in front of the parenthesis, the numbers in the parenthesis will bave to be solved instead of distributed.
B is not the answer because there are not even parenthesis to empasise the distibution.
A is not the asnwer because the numbers are simply being canceled out into the number 1 with a fraction and a whole number.
