Jeff can build 7 birdhouses in 5 hours. Use a
proportion to find out how long it would take
him to build 30 birdhouses. (Round answer to
nearest whole number)
Answer:
21 hours
Step-by-step explanation:
We can use a ratio to solve
7 houses 30 houses
------------- = --------------
5 hours x hours
Using cross products
7x = 5*30
7x = 150
Divide by 7
7x/7 =150/7
x =21.42857143
Rounding to the nearest whole number
x = 21 hours

Have a great day.
Plzzz help I don’t have a lot of time
Answer:
7
Step-by-step explanation:
It’s a right angle, so you can add the two expressions togther to get 90, then isolate x.
(8r-6)+(5r+5)=90
13r-1=90 (combine like terms)
13r-1+1=90+1 (add 1, addition property of equality)
13r=91
13r/13=91/13

(b) A telemarketing supervisor tells a new worker that the odds of making a sale on a single call are 4 to 19. What is the probability of a successful call
Answer:
0.1739 = 17.39% probability of a successful call.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
The odds of making a sale on a single call are 4 to 19.
This means that in 4 + 19 = 23 calls, 4 are successful.
What is the probability of a successful call?
[tex]p = \frac{4}{23} = 0.1739[/tex]
0.1739 = 17.39% probability of a successful call.

Simplify Complex Numbers
3.
√250 = √(25 * 10) = √(5^2 * 10) = √(5^2) * √10
… = 5 √10
=> a = 5
4.
√(-300) = √(-1 * 3 * 100) = √(-1 * 3 * 10^2) = √(-1) * √3 * √(10^2) = i * √3 * 10
… = 10i √3
=> -a = 10 and b = 3 => a = -10 and b = 3
=> a - b = -10 - 3 = -13
what that two numbers when multiplied give 600 and when added give 59
Answer:
Step-by-step explanation:
Let the 2 numbers be x and y
From the problem we have that
x * y = 600 and x + y = 59
From x + y = 59 -> x = 59 - y
Plug x = 59 - y to x * y = 600 we have
(59 - y) * y = 600
-> 59y - y^2 = 600
-> -y^2 + 59y - 600 = 0
-> y = [tex](59 - \sqrt{1081})/2[/tex] or [tex](59 + \sqrt{1081})/2[/tex]
Then we could plug the answers in and find x because x = 59 - y
In physics class, Carrie learns that a force, F, is equal to the mass of an object, m, times its acceleration, a. She writes the equation F=ma.
Using this formula, what is the acceleration of an object with F=7.92 newtons and m=3.6 kilograms? Express your answer to the nearest tenth.
The temperature measured in Kelvin (K) is the temperature measured in Celsius (C) increased by 273.15. This can be modeled by the equation K = C + 273.15.
When solved for C, the equation is
C = K – 273.15
C = 273.15 – K
C = K + 273.15
C = 273.15K

I need help finding the answer. Would appreciate some help
Answer:
a = 153.5 yd²
Step-by-step explanation:
horizontally divide the figure into a tringle and a trapezoid
triangle
a = (1/2)bh
a = (1/2)(19)(7)
a = 66.5
trapezoid
a = (b₁ + b₂)/2 * h
a = (19 + 10)/2 * (13 - 7)
a = 87
Combined
a = 66.5 + 87
a = 153.5

Find the point on the terminal side of θ = three pi divided by four that has a y coordinate of 1. Show your work for full credit.
Answer:
Remember that tan=y/x from your notes from module 4.
Step-by-step explanation:
Refer to the unit circle to see the relationship between x and y at that angle, it is -1. Now you can set up your equation of tan=1/x and solve for x.
For all the problems in this section you can set up an equation where tan=y/x, sin = y/h, and cos=x/h. Then using your equation you can solve for whatever number is missing.

Two of the desserts are sugar free
Three of the drinks are sugar free
Answer: 8/15
Step-by-step explanation:
You need part a of the question to answer this question correctly. In part a of the question it is said there is 6 sandwiches, 3 desserts and 5 drinks.
Two of the desserts are sugar free (2/3).
Four of the drinks are sugar free (4/5)
Times these fractions together, 2/3x4/5= 8/15.

What is the solution of the equation, 8y = 4?
A. y = 1/2
B. y = 2
c. y = 12
D. y = 32
Answer: A, which is y = 1/2
Step-by-step explanation: To find the value of y, you would need to divide both of the sides by 8. This makes it so that 8y turns into just y. After you do this, you would find an answer of y = 1/2. Hope this was helpful! :)
Answer:
y = 1/2
Step-by-step explanation:
8y = 4
Divide each side by 8
8y/8 = 4/8
y = 1/2

Step-by-step explanation:
A bicycle manufacturing company makes a particular type of bike. Each child bike requires 4 hours to build and 4 hours to test. Each adult bike requires 6 hours to build and 4 hours to test. With the number of workers, the company is able to have up to 120 hours of building time and 100 hours of testing time for a week. If c represents child bikes and a represents adult bikes, can the company build 20 child bikes and 6 adult bikes in a week.
No, because the bike order does not meet the restrictions of 4c + 6a ≤ 120 and 4c + 4a ≤ 100
No, because the bike order does not meet the restrictions of 4c + 4a ≤ 120 and 6c + 4a ≤ 100
Yes, because the bike order meets the restrictions of 4c + 6a ≤ 120 and 4c + 4a ≤ 100
Yes, because the bike order meets the restrictions of 4c + 4a ≤ 120 and 6c + 4a ≤ 100
9514 1404 393
Answer:
(a) No, because the bike order does not meet the restrictions of 4c + 6a ≤ 120 and 4c + 4a ≤ 100
Step-by-step explanation:
Build times are 4 hours for a child's bike and 6 hours for an adult's bike. The number of build hours cannot exceed 120. This gives the first inequality:
4c +6a ≤ 120
Test times are 4 hours each. The number of test hours cannot exceed 100. This gives the second inequality:
4c +4a ≤ 100
This pair of inequalities matches choices A and C.
When we use c=20 and a=6, these become ...
4(20) +6(6) = 116 ≤ 120 . . . true
4(20) +4(6) = 104 ≤ 100 . . . false
The order cannot be built because the test time constraint cannot be met. This matches choice A.

Why do we divide log2(4) by 15 and why log4(15) turned to log2(15) i need deep explanation and understand the rest but i didnt get where the first step came from
Answer:
see below
Step-by-step explanation:
log 4 (15)
We need to change the base from 4 to 2
log b (a) = log x(a) / log x(b) where x is the base that we need
log4 (15) = log 2 (15) / log 2 (4)
Express 240g as a percentage of 2.5kg
Answer:
0.1%
Step-by-step explanation:
Given that 240 g of 2.5 kg
We have to express this in percentage
But we know that 1 kg = 1000 g, So first convert 2.5 kg to g
2.5 kg = 2.5 x 1000 g = 2500 g
The formula of "a" % of "b" is given as:
[tex]percentage= \frac{a}{b}[/tex] × 100
Hence, 240 g as a percentage of 2500 g is given as:
[tex]= \frac{250}{2500}[/tex] × [tex]100[/tex]
= [tex]\frac{1}{10}[/tex] = 0.1
Thus, the answer is 0.1 %
