Step-by-step explanation:
Over the last week, the daily low temperatures in degrees Fahrenheit have been −2, 6.9, 17 1 2 , −5.1, 24, − 1 4 , and 1.45. List these numbers in order from greatest to least.
Answer:
24 > 17 1/2 > 6.9 > 2 > 1.45 > - 1/4 > - 5.1
Step-by-step explanation:
Given the following temperature values :
2, 6.9, 17 1/2 , −5.1, 24, − 1/4 , and 1.45.
Ordering the values above from greatest to least ; (descending order)
Expressing all temperature values in the same format :
Let's make sure all values are in decimal to make comparison easier :
2.0
6.9
17 1/2 = 35/2 = 17.5
-5.1
24.0
-1/4 = - 0.25
1.45
We begin from the temperature value which is highest :
24 > 17.5 > 6.9 > 2.0 > 1.45 > - 0.25 > - 5.1
Hence ;
24 > 17 1/2 > 6.9 > 2 > 1.45 > - 1/4 > - 5.1
3 − 3k + 7k = 5b find the equation for k
Answer:k=5b/4 - 3/4
Step-by-step explanation:
Answer:
[tex]k=\frac{5}{4}b - \frac{3}{4}[/tex]
Step-by-step explanation:
-3k + 7k = 5b - 3
4k = 5b - 3
[tex]k=\frac{5}{4}b - \frac{3}{4}[/tex]
Please help me with this question, I’m currently very busy and I need somebody’s help, it would be very appreciated
Answer:
The explicit formula that represents the amount of money left on the card
is a[tex]_{n}[/tex] = 53.25 - 3.25n
The value of the card after 12 lunches is $14.25
Step-by-step explanation:
The explicit formula of the arithmetic sequence is a[tex]_{n}[/tex] = a + (n - 1)d, where
a[tex]_{n}[/tex] is the nth terma is the first termd is the common difference between each 2 consecutive termsIn the question
∵ You have 50 dollars
∵ The money left after lunch on Monday is 46.75 dollars
∵ The money left after lunch on Tuesday is 43.50 dollars
∴ The terms of the sequence are 50, 46.75, 43.50
∵ 46.75 - 50 = -3.25
∵ 43.50 - 46.75 = -3.25
→ That means there is a common difference between each 2 terms
∴ d = -3.25
∵ a = 50
→ Substitute the values of a and d in the rule above
∴ a[tex]_{n}[/tex] = 50 + (n - 1)(-3.25)
→ Simplify it
∵ a[tex]_{n}[/tex] = 50 + -3.25(n) + -3.25(-1)
∴ a[tex]_{n}[/tex] = 50 - 3.25n + 3.25
→ Add the like terms
∴ a[tex]_{n}[/tex] = 53.25 - 3.25n
∴ The explicit formula that represents the amount of money left on the
card is a[tex]_{n}[/tex] = 53.25 - 3.25n
∵ n is the number of lunches
∴ n = 12
→ Substitute n by 12 to find the amount of money left on the card
∵ a[tex]_{12}[/tex] = 53.25 - 3.25(12)
∴ a[tex]_{12}[/tex] = 14.25
∴ The value of the card after 12 lunches is $14.25
Tony hit 9 out of 15 pitches at baseball practice yesterday. The following day at practice 45 pitches were made. How many pitches did Tony miss?
Answer:
18 pitches.
Step-by-step explanation:
I'm assuming the "9 out of 15" is the fraction of pitches Tony hit at baseball practice.
Hence, Tony missed 6 out of 15 pitches.
6/15 * 45
= 6 * 3
= 18 pitches.
Hope this helped!
Answer:
18
Step-by-step explanation:
You have to start with how many he hit.
Let the number of pitches he hit = x
9/15 = x / 45 Cross multiply
15x = 9 * 45 Combine the right side
15x = 405 Divide by 15
x = 405/15
x = 27
===================
The number he missed is 45 - 27 = 18

Rewrite x-3y=6 in slope intercept from
Answer: 1/3x -2
Step-by-step explanation:
X-3y =6 subtract x from both sides first
-3y=6-x. Then divide both sides by -3
Y= 6-x /-3 simplify
Y= -2+x/3 rearrange
Y= 1/3x -2

Find the value of sec theta, if cos theta =2/19; 0degrees less than and equal to theta less than and equal to 90 degrees.
a) 2/19
b) -19/2
c) -2/19
d) 19/2
Answer:
19/2
Step-by-step explanation:
This problem is a problem desgined to test your basic understanding of Trigonomic functions and there applictoins.
Sec theta is the inverse of cos theta, which means sec theta is equal to adjecent / opposite.
They already gave you cos theta which is 2/19
We should know that from 0 to 90 degrees, sec theta is postive.
so sec theta is 19/2

Will mark Brianliest !!!!!!!!!!!!!! Answer correctly please!!!!!
Answer:
x = 6
Step-by-step explanation:
Vertical angels are always equal, there fore angle A = angle B.
If angle A = angle B, and
angle A = 3x - 9 and angle B = x + 3, then
3x - 9 = x + 3
Now you can solve this like a regular inequality
Start by subtracting x by it's self then 3x to get both variables on one side.
2x - 9 = 3
Now you can add 9 to it's self and to 3 on the other side.
2x = 12
Finally, divide 2 by it's self and 12.
x = 6

Given a long algebraic equation, what are some strategies that you can use to make simplifying and evaluating the equation more efficient and accurate?
Answer:
See explanation
Step-by-step explanation:
Given a long algebraic equation, the like terms can be collected. When you collect like terms, you reduce the length of the algebraic equation.
After that, you can factorize the equation where possible. When you factorize the equation. It becomes quite easier to solve it efficiently.

(I didn't write this awnser it was written by
Katieg3593 I just thought I would share the awnser).
Three salesmen work for the same company, selling the same product. And, although they are all paid on a weekly basis, each salesman earns his paycheck differently.
Salesman A works strictly on commission. He earns $65 per sale, with a maximum weekly commission of $1,300.
Salesman B earns a weekly base salary of $300, plus a commission of $40 per sale. There are no limits on the amount of commission he can earn.
Salesman C does not earn any commission. His weekly salary is $900.
On any given week, if Salesman B earns $1,020, how many sales did he have for the week?
sales
I will give brainlest
Answer:
18
Step-by-step explanation:
So base of 300/week.
We subtract 300 from 1020, leaving 720.
Divide 720 by 40 (because that is the amount per sale), we get 18.
how would i find the slope and y intersept of 3y=5x-18
Answer:
y=5/3x−6
5/3 is your slope
Answer:
see explanation
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
3y = 5x - 18 ( divide all terms by 3 )
y = [tex]\frac{5}{3}[/tex] x - 6 ← in slope- intercept form
with slope m = [tex]\frac{5}{3}[/tex] and y- intercept c = - 6

Answer:
1. Perpendicular2. Neither3. ParallelStep-by-step explanation:
Finding slopes of the lines to determine their relationship
1. J(1, 9), K(7, 4), L(8, 13), M(-2, 1)
Slope of JK
m = (4-9)/(7-1) = -5/6Slope of LM
m = (1-13)/(-2-8) = -12/-10 = 6/5These lines are perpendicular as slopes are negative reciprocal
2 J(13, -5), K(2, 6), L(-1, -5), M(-4, -2)
Slope of JK
m = (6-(-5))/(2-13) = 11/(-11) = -1Slope of LM
m = (-1-(-5))/(-4-(-1)) = 4/(-3) = -4/3Lines are neither parallel nor perpendicular
3. J(-10, -7), K(-4, 1), L(-3, 2), M(-6, -2)
Slope of JK
m = (1-(-7))/(-4-(-10)) = 8/6 = 4/3Slope of LM
m = (-2-2)/(-6-(-3)) = -4/-3 = 4/3These lines are parallel as slopes are same
Answer:
1. Perpendicular
2. Neither
3. Parallel

Answer:
∠ JKL = 32°
Step-by-step explanation:
Since KN bisects ∠ LKM , then
∠ LKN = ∠ NKM = 35°
Thus
∠ JKL = ∠ JKM - ∠ LKN - ∠ NKM
= 102° - 35° - 35°
= 102° - 70°
= 32°
