The area of a rectangular field is 5734 m^2.
If the length of the field is 94 m, what is its width?
Answer:
Step-by-step explanation:
Area of rectangle=length x width
Given area= 5734 m^2.
Length=94m
So 5734=94xwidth
width=5734/94=61m is the answer
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
Line m passes through points (10, 10) and (2, 1). Line n is perpendicular to m. What is the
slope of line n?
Answer:
-8/9
Step-by-step explanation:
my work is in the picture above. lmk if you'd like me to explain more
The slope of line [n] would be -8/9.
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.

(8x+12)
Answer:
x = 16
DISREGARD 16.5 MY BAD the answer is 16
Step-by-step explanation:
140 = 8x+12
Subtract 12 on both sides
128 = 8x
Divide by 8
16 = x
x = 16
Answer:
x = 16
Step-by-step explanation:
(8x + 12)° = 140°
8x + 12 = 140
8x = 128
x = 128 ÷ 8
x = 16

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].

Calculate the total shaded area.
Take it to be 3.142 and write down all the digits given by your calculator.
Answer:
69.498
Step-by-step explanation:
first find the area of the whole square (how i saw it), remember
it is made up of a circle drawn inside a square.
so we do the area of the square = 18²
= 324
next we find the circle which was drawn, the circle covers up the
whole shaded square.
diameter would be 18 as the length of the square was 18,
then we find the radius, 18/2 = 9
now we use πr²,
r would be the radius (9)
therefore it would be π(81) and we get 254.502
now we take away the area of the circle covering the square
from the area shaded in,
therefore 324 - 254.502
= 69.498

what is the answer for this ?
Answer:
A
-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! :)))

Answer:
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]
How do functions work? Could someone explain how to know which questions are functions or not
Answer:
A function is an equation that has only one answer for y for every x. A function assigns exactly one output to each input of a speceified type. It is common to name a function either f(x) or g(x) instead of y. f(2) means that we should find the value of our function when x equals 2.
Step-by-step explanation:
here is a step by step equation:
f(x) = x + 7
if:
x=2
then:
f(2) = 2 + 7 = 9
A function is linear if it can be defined by
f(x) = mx + b

Step-by-step explanation:
suppose y varies directly with x, and y=25 when x=140. what is the value of y when x=36
Answer:
[tex]\displaystyle y=\frac{45}{7}[/tex]
Step-by-step explanation:
Direct Proportions
A direct proportion is a relation between variables where their ratio is a constant value. This means that if y and x are proportional, then:
[tex]\displaystyle \frac{y}{x}=k[/tex]
Where k is a constant.
We know y=25 when x=140, and it's required to find the value of when x=36.
For any pair of values (x,y), their ratio is constant:
[tex]\displaystyle \frac{25}{140}=\frac{y}{36}[/tex]
Multiplying by 36:
[tex]\displaystyle y=36*\frac{25}{140}[/tex]
[tex]\displaystyle y=\frac{900}{140}[/tex]
Simplifying:
[tex]\mathbf{\displaystyle y=\frac{45}{7}}[/tex]
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

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.
