Find the length of a rectangular lot with a perimeter of 144 m if the length is 6 m more than the width. A. 72m B. 39 m
C. 33 m
D. 78 m
Answer:
Correct Answer is B
39 m
Step-by-step explanation:
Perimeter is the sum of all sides, and if the length is 6m more than the width, then is 39
39 + 39 = 78
144 - 78 = 66
66/2 = 33
39m is 6m more than 33m.
The sum of all sides 39 + 39 + 33 + 33 = 144

Allison can jog 3 blocks in the same amount of time it takes her brother, Blake, to jog 2 blocks. If they keep jogging at the same rate, how many blocks will Blake jog if Allison jogs 18 blocks?
Answer:
Blake will jog 12 blocks
Step-by-step explanation:
Allison : Blake = 3 : 2
If they keep jogging at the same rate, how many blocks will Blake jog if Allison jogs 18 blocks?
Allison : Blake = 18 : x
Equate the ratios
3 : 2 = 18 : x
3/2 = 18/x
Cross multiply
3 * x = 2 * 18
3x = 36
Divide both sides by 3
x = 36 / 3
= 12
x = 12
Blake will jog 12 blocks
Answer:
12 blocks
Step-by-step explanation: she ran 12 blocks

Find the area of this sector
Answer:
7π mm²
Step-by-step explanation:
The area (A) of the sector is calculated as
A = area of circle × fraction of circle
= πr² × [tex]\frac{280}{360}[/tex] ( r is the radius )
= π × 3² × [tex]\frac{28}{36}[/tex]
= 9π × [tex]\frac{7}{9}[/tex] ( cancel the 9's )

y-6=-6(x-1)
Step-by-step explanation:
Hope this helps :D
have a nice thanksgiving
Answer:
[tex]y-6=-6(x-1)[/tex]
Step-by-step explanation:
A point-slope equation requires two values in order to write it: one coordinate and the slope.
First, find the slope between the two given points. To find the slope, you would subtract the first Y from the second Y and the first X from the second X. Y goes on top of the fraction bar, making the equation look like this:
[tex]\frac{6-(-6)}{1-3}[/tex]
Then, simplify the slope equation:
[tex]\frac{6-(-6)}{1-3} = \frac{6+6}{1-3} = \frac{12}{-2} = -6[/tex]
The slope is -6.
Finally, choose one of the coordinates. For this, I'll pick (1, 6).
The point-slope equation is [tex]y-y_{1} =m(x-x_{1})[/tex]
So, simply fill in the [tex]m[/tex], [tex]y_{1}[/tex] , and [tex]x_{1}[/tex] spots with the value we have found.
[tex]m[/tex] is the slope, so replace it with -6.
[tex]y_{1}[/tex] = 6
[tex]x_{1}[/tex] = 1
Final answer:
[tex]y-6=-6(x-1)[/tex]

What is the general equation of a Straight line?
The general equation of a straight line is -
y = mx + c
where -
[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].
[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis.
Other possible equations of lines are -
(y - y₁) = m(x - x₁) {Point - slope form}(y - y₁) = (y₂ - y₁) × (x - x₁)/(x₂ - x₁) {Two point - slope form}x/a + y/b = 1 {intercept form}x cos(β) + y sin(β) = L {Normal form}We have line [m] passes through points (10, 10) and (2, 1).
We can write the equation of line [m] as follows.
slope of line [m] = a = (1 - 10)/(2 - 10) = -9/-8 = 9/8
a = 9/8
slope of line [n] -
m[n] x a = - 1
m[n] = -1/a
m[n] = -8/9
Therefore, the slope of line [n] would be -8/9.

Answer:

-2 < x ≤ 3 (All x values between -2 and 3; excluding -2 and including 3)
Step-by-step explanation:
I feel the answer is A because from what we know, domain is the x-intercept or x. So both C and D are not the answer because the y-intercept is not the domain, the y-intercept is the range. Next I looked at both A and B, well, if you look closely answer choice A says "excluding -2 and including 3" and choice B says "including -2 and excluding 3". I also seen on the graph that the point of (3,3) has a filled in dot and the point at (-2,-1) has an opened dot. A filled in dot always means you either have a ≥ (greater than or equal to sign) or a ≤ (less than or equal to sign). While an opened dot always means you just have < (greater than) or a > (less than) sign. So the correct answer is A!! Hope you have a fantastic rest of your day! :)))

Company A charges $3.25 per spirit banner. The equation C=2.45x represents the cost in dollars, C, for x spirit banners at Company B. How much more would it cost to purchase 80 spirit banners from the more expensive company?
Answer:
$64.00
Step-by-step explanation:
Company A:
C = 3.25x
3.25 x 80 = 260
Company B:
C = 2.45x
2.45 x 80 = 196
How much more?
260 - 196 = 64
Difference in Total price for 80 unit is $84
Given that;Per spirit cost in company A = 3.5 per spirit
Cost equation for company B = C = 2.45x
Find:Difference in Total price for 80 unit
Computation:Difference in Total price for 80 unit = 80[3.5 - 2.45]
Difference in Total price for 80 unit = 80[1.05]
Difference in Total price for 80 unit = $84

At 11 p.M., it was 48°F. The temperature was 6° cooler by 7 a.M. By 11 a.M. The temperature was 48°F again. What integer represents the number of degrees the temperature changed from 7 a.M. To 11 a.M.?
Answer:
6°F
Step-by-step explanation:
Given that:
Temperature at 11pm = 48°F
Temperature at 7am = 6° cooler
Temperature at 11am = 48°F
Number of degrees temperature changed from 7am to 11 am
Exact temperature at 7am = (temperature at 11 pm - 6°)
= 48°F - 6°F
= 42°F
Temperature change from 7am to 11am
Temperature at 11 am - temperature at 7am
48°F - 42°F
= 6°F
Ennis ran 3 miles in 20 minutes and continues running at this rate for 1 hour. Cindy ran 6 miles in 30 minutes and continues running at this rate for 1 hour.
Answer:
Ennis=9 milesCindy=12 milesStep-by-step explanation:
Step one:
given data
For Ennis
distance covered= 3 miles
time taken = 20 minutes
Hence Ennis speed is
velocity= distance/time
velocity= 3/20
velocity=0.15miles per minutes
Therefore in 1 hour that is 60 minutes the distance she will cover is
distance= velocity * time
Distance= 0.15*60
Distance= 9 miles
Step two:
For Cindy
distance covered= 6 miles
time taken = 30 minutes
Hence Cindy speed is
velocity= distance/time
velocity= 6/30
velocity=0.2miles per minutes
Therefore in 1 hour that is 60 minutes the distance she will cover is
distance= velocity * time
Distance= 0.2*60
Distance= 12 miles
Function f gives the temperature, in degrees Celsius, t hours after midnight. Choose the equation that represents the statement: “At 1:30 p.m., the temperature was 20 degrees Celsius.” Group of answer choices f (1:30) = 20 f (1.5) = 20 f (13:30) = 20 f (13.5) = 20
Answer:
D.
Step-by-step explanation:
The function f gives the temperature in degrees Celsius t hours after midnight.
Therefore, for the temperature at 12:00 AM (exactly midnight), we will have f(0).
For 1:00 AM, 1 hour after midnight, we will have f(1).
And for 12:00 PM (noon), we will have f(12).
We want to find the equation that represents the temperature at 1:30 PM.
1:30 PM is 13.5 hours after midnight or 1.5 hours after noon.
Therefore, the correct statement would be:
f(13.5)=20.
Hence, our answer is D.

Find the value of X for the given pentagon?
Answer:
x = 44°
Step-by-step explanation:
The sum of the exterior angles of any polygon my be 360°, so just add all the angles up, and subtract this from 360°.
Given a pentagon with exterior angles: 102°, 47°, 34°, and 133° with the missing angle x°.
To find the missing angle, first write an equation representing the given rule:
102° + 47° + 34° + 133° + x° = 360°
(316°) + x° = 360°
316° + x° - 316° = 360° - 316°
x° = 44°.
This way, because the rule must be true, the missing angle with this value will satisfy this:
102° + 47° + 34° + 133° + 44° = 360°
For this topic, here are some general angle rules for polygons:
n is the number of sides180° (n – 2) = sum of interior angles of any polygon.180° (n – 2) / n = each interior angle of a regular polygon [all sides and or angles the same measure / congruent].360° = sum of exterior angles of any polygon.360° / n = each exterior angle of a regular polygon. [all sides and or angles the same measure / congruent].What is the missing step in this proof?
