solve the following equation for the value of k. SHOW UR WORK!
Answer:
k = -4
Step-by-step explanation:
First multiply 3 for both sides of the equation:
- 9 = k - 5
Then isolate k to get
k = -4
Answer:
K is equal to -14
Step by step:
3 x 3 = 9
We need 3 wholes.
5 + 9 = 14
14 - 5 = 9
K represents -14
Hope this helps!
Chloe is planning an event and purchasing floral arrangements. At Petals Plus, the arrangements cost $35.17 each, and the store
charges $67.00 for delivery of the flowers to the event site. At Blooms, the arrangements cost $25.03 each, and the store charges
$108.00 for delivery of the flowers to the event site.
How many arrangements should she purchase from Blooms in order to get a better value?
OA. 3
OB. 5
OC. 1
OD. 4
Answer: You would need at least 5 arrangements to make Blooms a better deal
Step-by-step explanation:
Petals Plus
y= 35.17x+67
Blooms
y= 25.03x+108
35.17x+67 =25.03x+108
10.14x= 41
x= 4.05
The average person's stride lenghth the distance covered by one step is aproximently 2.5 feet long. How many steps would the average person take to travel 50 feet?
Answer: 20 steps
Step-by-step explanation:
From the question, we are informed that the average person's stride length the distance covered by one step is 2.5 feet long.
To know the steps that the average person would take to travel 50 feet, we simply have to divide 50 feet by 2.5 feet. This will be:
= 50 / 2.5
= 20
This means that an individual will take 20 steps to travel 50 feet

What is the area of a
sector in a circle with a
7 m. radius and a central
angle of 100°?
Answer:
42.74 m²
Step-by-step explanation:
full circle area = πr² = (3.14)(7²) = 153.86 m²
(100°/360°)(153.86 m²) = 42.74 m²

A triangle has sides that are 3, 7, and squareroot 57. Is the triangle a right triangle?
Answer:
my answer is no because for a right angle triangle the sum of the squares of the other two sides is equal to the square of the longest side
3²+7²=9+49=58
(√57)²=57
57≠58 it's not a right angle triangle
assume the sides to be a,b and c
a=3 b=7 c=√57
by Pythagoras theorem
a²+b²=c²
3²+7²=√57²
but 58≠57
hope it's clear
HELP!!! A scientist needs 10 litters of 20% acid solution for an experiment, but she has only a 5% solution and a 40% solution. To the nearest tenth of a liter, about how many liters of the 5% and the 40% solutions should she mix to get the solution she needs
Answer:10 liter * 20%= x liter*40% + (10- x) liter*5%
10l * 20%= x liter * 35% + 10 liter*5%
x liter *35 = 10l * 20 - 10l *5= 10l*15
x liter = 10l *15/35= 4.28 L= 4.3L
The volume of 40% solution= 4.3L
The volume of 5% solution= 10L- 4.3L= 5.7L
Step-by-step explanation:
In this question, you want to make 10 liters 20% concentration solution by mixing 5% and 40% concentration. There should be multiple answers to this question. Assuming that the total volume of 5% and 40% solution equal to 10L(no solution wasted), then you can determine the volume of solution needed. The formula should be:

The base of a triangle is 24 millimeters and the height is 7 millimeters. What is the area of the triangle?
Answer:
84
Step-by-step explanation:
area of a triangle is represented by this equation: A= 1/2(b x h)
so we plug in the base for b and the height for h to get A=1/2(24 x 7) and now we solve accordingly. 24 x 7 is 160, and 160 x 1/2 is 84.

A point is reflected in the x-axis. The reflected point is (3,−9). What is the original point? The original point is ( , ). Question 2 What is the distance between the points? The distance between the points is units.
Answer:
The original point is [tex]P(x,y) = (3,9)[/tex].
The distance between the points is 18 units.
Step-by-step explanation:
The reflection of a point with respect to the x-axis is defined by the following operation:
[tex]P(x,y) = (x,y) \to P'(x,y) = (x, -y)[/tex] (1)
Where:
[tex]P(x,y)[/tex] - Original point.
[tex]P'(x,y)[/tex] - Resulting point.
If we know that [tex]P'(x,y) = (3, -9)[/tex], then the original point is [tex]P(x,y) = (3,9)[/tex].
The original point is [tex]P(x,y) = (3,9)[/tex].
The distance between the points ([tex]d[/tex]), in units, is determined vectorially by the following expression, which is equivalent to the Pythagorean Theorem:
[tex]d = \sqrt{[P'(x,y) -P(x,y)]\,\bullet\,[P'(x,y) -P(x,y)]}[/tex]
[tex]d = \sqrt{(0,18)\,\bullet (0,18)}[/tex]
[tex]d = \sqrt{0^{2}+18^{2}}[/tex]
[tex]d = 18[/tex]
The distance between the points is 18 units.
Answer:(3,9) Distance 18 units.

. Larry solved this equation. 3(2-3)= x Which representation could Larry have used to solve this equation?
Answer:
x = -3
Step-by-step explanation:
Given the expression solved by Larry as;
3(2-3) = x
We are to find the equivalent expression x
Using the distributive law;
3(2) - 3(3) = x
6 - 9 = x
-3 = x
Swap
x = -3
Hence Larry could use the distributive law to solve the expression

Filipe is buying materials for making his new comic books. He purchases a notebook for $7
and when he rings up it shows he also owes $0.42 in tax. If he buys markers the next day for
$6 and pays the same tax rate, how much will he pay in tax?
Answer:$0.36
Step-by-step explanation:
0.42 devided by 7= 0.06
0.06 times 6= 0.36
Answer:
He would pay $0.36 the next day if he buys markers and pays the same tax rate as day 1.

A figure is shown Below
Find M
Answer:
58 degrees
Step-by-step explanation:
We know that angles on a straight add up to 180 degrees. Therefore:
To find the angle at the top of the triangle do 180-112 = 68
To find the angle at the right side of the triangle do 180 - 126 = 54
We know that angles in a triangle add up to 180 degrees. Therefore:
To find m do 180 - (54 + 68) = 58

Sergei's car was clocked in a quarter mile race at 146.67 miles per hour.
How many feet per second is this to the nearest hundredth if there are 5280 feet in one mile?
A. 29.33 feet per second
B. 35.99 feet per second
C. 215.12 feet per second
D. 733.35 feet per second
E. 860.48 feet per second
Answer:
C. 215.12 feet per second
Step-by-step explanation:
Sergei's car was clocked in a quarter mile race at 146.67 miles per hour.
How many feet per second is this to the nearest hundredth if there are 5280 feet in one mile?
From the above question
1 mile = 5280 feet
1 hour = 60 minutes
1 minutes = 60 seconds
1 hour = 60 × 60 seconds = 3600 seconds
We are to convert 146.67 miles per hour = feet per second
Hence:
146.67 miles /1 ft × 5280 feet/1 miles × 1 hr/3600 seconds
= 146.67 × 5280 feet/3600 seconds
= 774417.6 feet / 3600 seconds
= 215.116 feet per second.
Approximately = 215.12 feet per second

It takes Carol 30 minutes to drive to work using two roads. She drives 24 mph on a small road for hour. Then she drives 56 mph on a highway for hour. How far does Carol travel to work?
Complete question :
It takes Carol 30 minutes to drive to work using two roads. She drives 24 mph on a small road 1/2 for hour. Then she drives 56 mph on a highway for 1/4 hour. How far does Carol travel to work?
Answer:
26 miles
Step-by-step explanation:
The distance traveled is given by :
Distance = speed * time
Distance covered on small road :
24 mph * 1/2 hours = 12 miles
Distance covered in highway :
56 mph * 1/4 hours = 14 miles
Total miles traveled = 12 + 14 = 26 miles

Step-by-step explanation:
A farmer needs to plant 180 tomato plants. He can plant 9 plants every 15 minutes.
a) What percentage of the planting will be complete after 75 minutes?
It will be
% complete.
b) How many minutes will it take to finish 90% of the planting?
It will take ____ minutes.
Answer:
52.94%
270 minutes
Step-by-step explanation:
1. 9 plants - 15 minutes
x plants - 75 minutes
Cross multiply
15x = 75 x 9
15x = 675
Divide both sides by 15
x = 675/15
x = 45 plants
45/85 x 100
= 52.94%
2. 90% of 180
= 90/100 x 180
= 162 plants
9 plants - 15 minutes
162 plants - x minutes
Cross multiply
9x = 162 x 15
9x = 2430
Divide both sides by 9
x = 2430/9
x = 270 minutes or 4 hours 30 minutes.
Karen is working on her math homework. She solves the equation b/7
= 35 and says that the solution is b = 5. Do you agree or disagree with Karen?
Answer:
disagree
Step-by-step explanation:
subtituting b with 5 we get 5/7=35. they are not equal do karen is not correct.
Answer:
No
Step-by-step explanation:
If the equation was 7b=35 then yes Karen would be correct. However the equation is b/7=35 which would get you b = 245
Prism A is a triangular prism. The triangular base has a base of 7 meters and height of 9 meters. The prism has a height of 4 meters. Prism B is a rectangular prism with length of 8 meters, width of 2 meters, and height of 8 meters. Which prism has the least volume? Prism '
*see attachment for the diagram of the prisms
Answer:
Prism A
Step-by-step explanation:
✔️Volume of triangular prism (Prism A) = ½×bhl
b = 7 m
h = 9 m
l = 4 m
Volume of Prism A = ½ × 7 × 9 × 4
Volume of Prism A = 126 m³
✔️Volume of rectangular prism (Prism B) = L × W × H
L = 8 m
W = 2 m
H = 8 m
Volume of Prism B = 8 × 2 × 8 = 128 m³
✔️Prism A has the least volume
Answer:
Prism A has the least volume!
