Does this graph represent a proportional relationship between days and inches?
Explain your reasoning
3:20 what time will it be in 35 minutes
Answer: 3:55
Add 20 and 35, to get the number of minutes out of 60.
20 + 35 = 55
The time will be 3:55 35 minutes after 3:20.
Hope this helps you!
Answer:
It will be 3:55 because 20 plus 35 equals 55 making it 3:55 in the next 35 minutes.
Step-by-step explanation:
20+35=55

Answer:
TAG is described as an acute angle.
Step-by-step explanation:
This is because TAG is an angle that is less than 90 degrees.
Answer:
acute
Step-by-step explanation:
TAG
think of the angle, the gap is small and T is close to G
if it would be right the T would be upright
if it was straight T would lay flat corresponding to G making a line
if it was obtuse the gap would surpass the right angle outward
if the angle HMA is a right angle, the measure of angle SMH = 66 degrees, and angle SMH is complementary to angle HME, find the measure of angle SMA
Answer:
SMA= 24 degrees
Step-by-step explanation:
add the other given angles together: 66 + 90= 156
subtract 158 from 180 (every triangle has a total of 180 degrees): 180-156 = 24

Answer:
AOB = -8x + 68
Step-by-step explanation:
AOC = 40°
BOC = 8x - 28
Angle Addition Theorem:
AOB + BOC = AOC
AOB + (8x - 28) = 40
AOB + (8x - 28) + 28 = 40 + 28
AOB + 8x - 8x = 68 - 8x
AOB = -8x + 68
AOB + BOC = AOC
(-8x + 68) + (8x - 28) = 40
-8x + 8x + 68 - 28 =40
0x + 40 = 40
40 = 40

Answer:
C
Step-by-step explanation:
What of the following statements describes a zero slope? Check all that apply.
The line goes up when moving right to left.
The line goes down when moving right to left.
The line is horizontal.
The line is vertical.
The run is zero.
The rise is zern
Answer:
A,D,E
Step-by-step explanation:
Answer:
A) The line goes up when moving right to left
False. The slope being zero means there is no change in elevation or height. The line is completely flat and horizontal. Recall that slope = rise/run. If the slope is 0, then the rise must be 0.
B) The line goes down when moving right to left.
False. The same reasoning as choice A
C) The line is horizontal
True. Any line with a slope of zero is going to be horizontal. For instance, the equation y = 0x+5 is the horizontal line through 5 on the y axis.
D) The line is vertical
False. This contradicts choice C above. Vertical lines have undefined slopes which aren't numbers due to the fact we cannot divide by zero.
E) The run is zero
False. The run can be any number but zero. For example, slope = 0 = 0/1 or 0 = 0/5. Dividing zero over any nonzero number leads to 0.
F) The rise is zero
True. As mentioned before in previous answer choices (see choice A in particular).
===========================================
In summary, there are only two true statements and they are choice C and choice F. The other statements are false.

Step-by-step explanation:
In the process of making a financial forecast, Farid has been looking closely at his
variable expenses. Currently, each week he spends an average of $25 on food, $30 on
entertainment, and $40 on clothing and other purchases. If Farid reduced his variable
expenses in each of these three categories by $7 a week, how much would he save
over the course of one year?
Answer:
1092
Step-by-step explanation:
first calculate expense for each week;
25+30+40= 95
expense after saving
25-7= 18
30-7=23
40-7=33
18+23+33= 74
total saving for each week= 95-74=21
(you can also just do 7*3=21 to know total saving each week)
weeks in a year=
365 days/7= 52.14 = 52 weeks
total savings for the year= 52*21=$1092
Answer:
$1092Step-by-step explanation:
There are 3 variables
Food, entertainment and clothing and other purchasesSaving amount is
$7 per each variable per weekTotal saving per week is
$7*3 = $21Saving per year considering 52 weeks per average year is:
$21*52 = $109210. Which polynomial expresses the difference of these two polynomials?
(74+6% - 10) - (- 346 - 7k + 1)

For membership to an athletic club, it costs $110 to join and $25 per month of membership. Write an equation to show the situation
Answer:
110 + 25x = Total Cost (or any type of variable needed, like a,b,c, etc.)
Step-by-step explanation:
Since the monthly fee occurs more than once, and we don't have the number of months, we put an x to represent the amount of months. The $110 is the one time additional fee for the membership, so it doesn't need a variable.
ANSWER>> DETERMINE THE RANGE OF THE FUNCTION.
.
y = 1/4x^2 - 5
.
A) All real numbers.
B) All integers less than or equal to -5.
C) All integers greater than or equal to -5.
D) All real numbers greater than or equal to -5.
Answer:
D
Step-by-step explanation:
When the function or the coefficient in this case 1/4x^2 is positive it means it's opening up like a u, meaning all the values will be bigger than the C term or -5 in this case.
Answer:
D
Step-by-step explanation:
the function is open-up shape, and the vertex is (0,-5)
Because it opens up, the vertex is minimum value.
range is equal to or greater than -5
Find the area A of polygon CDEFGH with the given vertices. C(0,5), D(2,5), E(2,3), F(3,2), G(-1,2), H(0,3)
Answer:
The area of the polygon CDEFGH is 7
Step-by-step explanation:
Area of a Polygon
The area of a polygon is generally calculated as the sum of the smaller areas that form its full shape, give each partial area has a known shape, like a square, rectangle, triangle, circle, etc.
The six points given in the question are plotted in the image below. They form a polygon whose area can be divided into two smaller shapes:
The area CDHE is a square of length side 2. Area of a square:
[tex]A1=L^2[/tex]
The area HEFG is a trapezoid with bases lengths 4 and 2, and height 1. Area of a trapezoid:
[tex]\displaystyle A2=\frac{b1+b2}{2}h[/tex]
Calculate both areas:
[tex]A1=2^2=4[/tex]
[tex]\displaystyle A2=\frac{2+4}{2}\cdot 1=3[/tex]
Total Area=4+3=7
The area of the polygon CDEFGH is 7
Can someone help I have a second chance
Answer:
rewrite equation 2 for x
x=8-7y
plug in x for equation 1
3/8*(8-7y)+1/3y=17/24
solve for y
3-17/24=21/8y-1/3y
55/24 = 55/24y
y=1
sub y back into eq. 2

What is the equation in slope-intercept form of the line that passes through the points ( -4, 47) and ( 2 , -16)?
ANSWER CHOICES BELOW...ANSWER CORRECTLY PLZ TAKING INTERIM NOW
Answer:
C
Step-by-step explanation:
Slope intercept form equation is y=mx+b
M=Slope
Slope equation is y2-y1 over x2-x1
So -16 - 47 over 2- (-4)
-63 over 6
Divide by 3 to simplify
= -21 over 2
Keep that as your answer for slope because a mixed number can't be used for slope but an improper fraction is perfectly fine
To find b use one point given (I chose to use (2, -16)
Plug that in and your slope to find b
-16= -21/2 (2) +b
-16= -21+b
+21 +21
5=b
Now plug that in and youre done
Y= -21/2x + 5

A line passes through the points (−4,−9)
and (−2,−6) What is the equation of the line in Slope-Intercept Form?
Answer:
D. [tex] y - 5= 3(x - 1) [/tex]
B. [tex] y = \frac{3}{2}x - 3 [/tex]
Step-by-step explanation:
Problem 1:
Point-slope form equation is given as [tex] y - y_1 = m(x - x_1) [/tex], where, (x1, y1) is a point on the line, and m = slope.
Find the slope of the line of the graph given, using 2 points on the line, points (0, 2) and (1, 5).
[tex] m = \frac{y_2 - y_1}{x_2 - x_1} = \frac{2 - 5}{0 - 1} = \frac{-3}{-1} = 3 [/tex]
Substitute (x1, y1) = (1, 5) and m = 3 into [tex] y - y_1 = m(x - x_1) [/tex]
[tex] y - 5= 3(x - 1) [/tex]
The answer is D.
Problem 2:
Slope-intercept equation takes the form: [tex] y = mx + b [/tex], where, m = slope, and b = y-intercept.
Find m and b.
Given, points (−4,−9) and (−2,−6),
[tex] slope(m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{-6 -(-9)}{-2 -(-4)} = \frac{3}{2} = \frac{3}{2} [/tex]
Substitute x = -2, y = -6, and m = ³/2 into [tex] y = mx + b [/tex], to find b:
[tex] -6 = \frac{3}{2}(-2) + b [/tex],
Subtract b from both sides
[tex] -6 = -3 + b [/tex]
Add 3 to both sides
[tex] -6 + 3 = b [/tex]
[tex] -3 = b [/tex]
[tex] b = -3 [/tex]
Substitute m = ³/2, b = -3 into [tex] y = mx + b [/tex]
[tex] y = \frac{3}{2}x + (-3) [/tex]
[tex] y = \frac{3}{2}x - 3 [/tex]
The answer is B.

What is HCF of 5a and 15a
Please help me I don’t understand
Answer:
5a.
Step-by-step explanation:
The HCF is short for Highest Common Factor.
Write the 2 expressions in factor form:
5a = 5 * a
15a = 5 * 3 + a
Note that 5 and a are common to both sets of factors, so the HCF = 5a.
