Tom is making potato salad for family picnic At the market he spends $5.58 on red potatoes and $4.68 on yellow potatoes If each type of potato cost $0.90 per pound, how many total pounds of potatoes does he buy?
Answer:
11.4
Step-by-step explanation:
Answer:
11.4 lbs of potatoes total
Step-by-step explanation:
$5.58 red potatoes
$4.68 yellow potatoes
$0.90 per pound
5.58 / 0.90 = 6.2 lbs
4.68 / 0.90 = 5.2 lbs
5.2 + 6.2 = 11.4

You are going to make a large poster for a school project. To prepare, you make a scale drawing of the poster before creating the real thing. The dimensions of the scale drawing are 4 inches by 9 inches. The dimensions of the real poster will be 20 inches by 45 inches. What is the scale factor?
Answer:
5
Step-by-step explanation:
You are going to make a large poster for a school project. To prepare, you make a scale drawing of the poster before creating the real thing. The dimensions of the scale drawing are
The dimensions of the real poster will be 20 inches by 45 inches.
The dimensions of the scale Drawing
= 4 inches by 9 inches.
We can see the inches of the real poster increased from the one of the scale drawing
The scale factor is calculated as:
20 ÷ 4/45 ÷ 9
= 5/ 5
Hence, the scale factor is 5
Both the width and length of the scale drawing was multiplied by 5 to get the length of the real poster

not really a work question but how do i deal with a friend who only calls me just to rant/complain?
Answer say your busy
Step-by-step explanation:
or just let it go to voicemail
Don't brush them off right off the bat. If they have time to rant about only their problems then you should be able to voice your complaints too. I'm not saying to turn the conversation into an argument but try to find a common ground and come to an agreement. Maybe they feel safe leaving their thoughts with you are just like rambling. Well whatever the reason you should also get the same respect you give of listening to your friends problems. All friendships are different but I hope I helped in the slightest.
One angle of a triangle measured 70 the other two angles are in a ratio of 7 : 15 what are the measures of those two angles
Answer:
35°, 75°
Step-by-step explanation:
Let the measures of the remaining two angles be 7x and 15x
By interior angle sum Postulate of a triangle.
70° + 7x + 15x = 180°
22x = 180° - 70°
22x = 110°
x = 110°/22
x = 5°
7x = 7*5° = 35°
15x = 15*5° = 75°
2/3y - 2/5 = 5, what is the value of y? *
Answer:
y=3.6 or 18/5 or you can turn it into any other fraction
Step-by-step explanation:
2/3y - 2/5 = 5
+2/5 +2/5
2/3y = 27/5
multiply by 2/3 on both sides
y=3.6 or 18/5 or you can turn it into any other fraction
L.B. Johnson Middle School held a track and field event during the school year. Miguel took part in a four-person shot put team. Shot put is a track and field event where athletes throw (or “put”) a heavy sphere, called a “shot,” as far as possible. To determine a team score, the distances of all team members are added. The team with the greatest score wins first place. The current winning team’s final score at the shot put is 52.08 ft. Miguel’s teammates threw the shot put the following distances: 12.26 ft., 12.82 ft., and 13.75 ft. Exactly how many feet will Miguel need to throw the shot put in order to tie the current first-place score? Show your work.
Answer:
11.25 ft
Step-by-step explanation:
To determine a team score, the distances of all team members are added.
The current winning team’s final score at the shot put is 52.08 ft.
So, in order to tie the score Miguel's team must equal the above score.
The total score before Miguel's throw was 12.26+12.82+13.75= 38.83 ft
so , Miguel will have throw 52.08-38.83= 11.25 ft in order to tie the score.

Answer:
here are 1000 meters in a kilometer so the conversion factor is 1000. To change within the metric system it is helpful to visualize the metric system ... Going up the staircases moves the decimal point one place to the left for each step. ... to convert 65 km to metres, you choose the conversion factor

please help me Herbert and Samantha are both driving from Orlando to Miami. Herbert
leaves at 9:00 and averages 60 mph (miles per hour) on the way. Samantha
leaves at 9:10 and averages 65 mph on the way. The situation is modeled by
this system, where x is the number of hours after Samantha leaves and y is
the distance each will travel:
y = 60x + 10
y = 65x
How long after Samantha leaves will she pass Herbert, and how far will they
each have traveled?
A. Samantha will not pass Herbert, because she will never catch up
with him
B. Samantha will pass Herbert after 3 hours, and they each will have
traveled 180 miles.
O C. Samantha will pass Herbert after 2 hours, and they each will have
traveled 130 miles.
O D. Samantha will pass Herbert after 3 hours, and they each will have
traveled 190 miles.

I need to find the answer for d
[tex]\tt Step-by-step~explanation:[/tex]
To solve for d, we have to move all the terms that do not equal to d to one side of the equation and leave d on the other side.
[tex]\tt Step~1:[/tex]
First, subtract n from both sides.
[tex]\tt 9d+n-n=57-n\\9d=57-n[/tex]
[tex]\tt Step~2:[/tex]
Divide all terms by 9 to get the variable d by itself.
[tex]\tt \frac{9d}{9} =d\\\\\frac{-n}{9} =-\frac{n}{9}\\\\\frac{57}{9}=6\frac{1}{3} ~or~\frac{19}{3} \\\\d=-\frac{n}{9} +\frac{19}{3}[/tex]
[tex]\Large\boxed{\tt Our~final~answer:~d=-\frac{n}{9} +\frac{19}{3} }[/tex]
[tex] \LARGE{ \underline{ \pink{ \bf{Required \: answer:}}}}[/tex]
Since there are two variables in the equation and no other simultaneous equation is not given, We need to express d in terms of other elements in the equation.
GiveN:
9d + n = 57So, Let's find d from the above equation. Subtracting n from both sides of the equation.
⇛ 9d = 57 - n
Now dividing the equation by 9,
⇛ 9d / 9 = 57 - n / 9
⇛ d = 57 - n / 9
Thus, the required answer for d is:
[tex] \boxed{ \rm{d = \frac{57 - n}{9} }}[/tex]
And we are done ......

If sin theta + cos theta=mand sec theta+ cosec theta =n then n(m+1)(m-1)=?
sin A + cos A = m -- equation (1)
sec A + Cosec A = n -- equation (2).
Find:value of n(m+1)(m-1)
Solution:We have to find:
n(m + 1)(m - 1)
using (a + b)(a - b) = a² - b² we get,
⟹ n (m² - 1²)
⟹ m²n - n
Putting the values from equations (1) & (2) we get,
⟹ (sin A + cos A)² * (sec A + Cosec A) -
(sec A + Cosec A)
(a + b)² = a² + b² + 2ab
⟹ (sin² A + cos² A + 2sin A Cos A ) * (sec A + Cosec A) - sec A - Cosec A
using the identity sin² A + cos² A = 1 we get,
⟹ ( 1 + 2 sin A cos A ) * (sec A + Cosec A) - sec A - Cosec A
⟹ 1(sec A + Cosec A) + 2sin A cos A(sec A + Cosec A) - sec A - Cosec A
⟹ sec A + Cosec A + 2 sin A * cos A * sec A + 2 sin A cos A Cosec A - sec A - Cosec A
using sin A * Cosec A = 1 & cos A * sec A = 1 we get,
( sec A + Cosec A & - sec A - Cosec A are being cancelled )
⟹ 2 sin A + 2 cos A
⟹ 2 (sin A + cos A)
Putting the value sin A + cos A from equation (1) we get,
⟹ 2m
∴ n (m + 1)(m - 1) = 2m.

A linear function is shown on the graph and in the table.
What are the slope and y-intercept of the linear function?
A) The slope is - 1/3 and the y-intercept is 147.
B) The slope is 3 and the y-intercept is 147.
C) The slope is –3 and the y-intercept is 150.
D) The slope is 1/3 and the y-intercept is 150.
Answer:
slope is -3, y-intercept is 150 [C]
Step-by-step explanation:
The slope is –3 and the y-intercept is 150. Therefore, option C is the correct answer.
What is slope of a line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The formula to find the slope of a line is slope = (y₂-y₁)/(x₂-x₁).
From the table we have (1, 147) and (3, 141).
Here, slope (m) = (141-147)/(3-1)
= -6/2
= -3
Substitute m=-3 and (x, y)=(1, 147) in y=mx+c, we get
147=-3(1)+c
c=147+3
y-intercept =c=150
Therefore, option C is the correct answer.
