Answer:
x = 9
y = 56
Step-by-step explanation:
(3x + 7)° + (6x + 2)° = 90° (both angles are complementary)
Find the value of x using this equation
[tex] 3x + 7 + 6x + 2 = 90 [/tex]
Collect like terms
[tex] 3x + 6x + 7 + 2 = 90 [/tex]
[tex] 9x + 9 = 90 [/tex]
Subtract 9 from each side
[tex] 9x + 9 - 9 = 90 - 9 [/tex]
[tex] 9x = 81 [/tex]
Divide both sides by 9
[tex] \frac{9x}{9} = \frac{81}{9} [/tex]
[tex] x = 9 [/tex]
y° = (6x + 2)° (both angles are vertical angles. Vertical angles are equal)
Plug in the value of x to find y
y = 6(9) + 2
y = 54 + 2
y = 56

Dana saved 450 for food for her upcoming vacation. The breakfast was included with their hotel, but lunch and dinner are not. When Dana cooks lunch or dinner it costs on average 10 . When the family goes to a restaurant for lunch or dinner it costs on average 40 . Let c represent meals that Dana cooks and let r represent meals the family goes to restaurants for. Write an inequality to represent the situation.
Answers
Answer:
[tex]10d + 40r \leq 450[/tex]
Step-by-step explanation:
Given
[tex]Savings = 450[/tex]
[tex]Dana\ Cooks, d = 10[/tex]
[tex]Restaurant, r = 40[/tex]
Required
Represent this as an inequality
When Dana cooks;
[tex]Cost\ per\ meal = 10[/tex]
[tex]Cost\ per\ d\ meals = d * 10[/tex]
[tex]Cost\ per\ d\ meals = 10d[/tex]
At Restaurant
[tex]Cost\ per\ meal = 40[/tex]
[tex]Cost\ per\ r\ meals = 40 * r[/tex]
[tex]Cost\ per\ r\ meals = 40 r[/tex]
Add these two results:
[tex]Result = 10d + 40r[/tex]
To represent as an inequality, the above result must be less than or equal to Dana's total savings
i.e.
[tex]10d + 40r \leq 450[/tex]

A florist has 49 red roses and 63 white roses. The florist wants to put an equal number of red roses in each centerpiece, along with an equal number of white roses in each, using all the flowers. What is the greatest number of centerpieces the florist can make, and how many of each flower will they have?
Answers
49 can be equally divided by seven, which means there would be 9 red roses in each center piece. And 63 can be equally divided by 7 which means there would by 7 white roses in each center piece.
hope this helps
Number of red roses a florist has = 49
Number of white roses a florist has = 63
To find the number of centerpieces with equal number of white and red roses we will find the greatest common factor of both the numbers,
49 = [tex]7\times 7[/tex]
63 = [tex]7\times 9[/tex]
GCF of 49 and 63 = 7
Therefore, number of centerpieces = 7
Now divide the total number of red roses by GCF to find the number of red flowers in each centerpiece.
Number of red roses in each centerpiece = 7
Similarly, number of white roses in each centerpiece = 9

An environmental study of a certain community suggests that t years from now, the average level of carbon monoxide in the air will be Q(t)=0.05t^2 + 0.1t + 3.4 parts per million. By approximately how much will the carbon monoxide lvel change during the coming 6 months?
Answers
Answer:
3.4625
Step-by-step explanation:
Given the equation:
Q(t)=0.05t^2 + 0.1t + 3.4 parts per million
Where t = time in years
By approximately how much will the carbon monoxide lvel change during the coming 6 months?
t = 6 months = 6/12 = 0.5 year
Q(0.5) = 0.05(0.5)^2 + 0.1(0.5) + 3.4 parts per million
Q(0.5) = 0.05(0.25) + 0.05 + 3.4
Q(0.5) = 0.0125 + 0.05 + 3.4
Q = 3.4625
Carbon monoxide level will change by approximately 3.4625 parts per million in 6 months
