The picture shows a triangular island
Which expression shows the value of c?
b/tan 45°
b/COS 45°
a cos 45º
a tan 45°
=============================================
Work Shown:
cos(angle) = adjacent/hypotenuse
cos(45) = b/c
c*cos(45) = b
c = b/cos(45)
In the third step, I multiplied both sides by c. Afterward, I divided both sides by cos(45) to isolate c.
Answer:
ans: b/cos45
Step-by-step explanation:
as we know that cos45=b/c
then, c/b=1/cos45
therefore, c=b/cos45

Your class is selling boxes of flower seeds as a fundraiser. The total profit p depends on the amount x that your class charges for each box of seeds. The equation
p= -0.53 +25x - 120
models the profit of the fundraiser. What's the
smallest amount, in dollars, that you can charge and make a profit of at least $105?
Answer:
$9.03
If you want smallest amount it dollars, you have to go with $9. However, this will only give you a profit of $104.47
Step-by-step explanation:
p = -0.53 +25x - 120
105 = -0.53 +25x - 120
225.53 = 25x
x = 9.0212
Check work:
105 = -0.53 +25(9.02) - 120
105 ≠ 104.97
Since $9.02 doesn't equal $105 profit, let's add a penny to make it $9.03.
105 = -0.53 +25(9.03) - 120
105 ≠ 105.22
If you charge $9.03 for each box you will make a profit of at least $105.
Round to smallest amount in dollars:
105 = -0.53 +25(9) - 120
105 ≠ 104.47
3^10 + 3^10 + 3^10=
a)9^30
b)3^30
c)9^10
d3^11
Answer:
As a^m+a^m+a^m=a^m+m+m or (a+a+a)^m {WHEN BASES ARE SAME WE CAN ADD THE BASES TOGETHER AND PUT THE POWER (IN CASE OF ADDITION) AND WHEN POWERS ARE SAME WE CAN ADD THE POWERS AND LET THE BASE REMAIN SAME}
So,
(3+3+3)^10 and 3^10+10+10 is also true (only because both the basesa nd the powers here are the same)
So,
9^10 and 3^30
So option b and c are correct

Rafael writes an expression to represent “a number, n, decreased by thirty-one.” Then he evaluates that expression if n = 29. Which statements are true about the expression and its evaluation? Check all that apply.
The correct expression is 31 minus n.
This is a subtraction expression.
This is an addition expression.
To evaluate, substitute 29 for the variable in the expression.
To evaluate, substitute 31 for the variable in the equation.
To evaluate the expression, add 31 to 29.
The correct expression is n minus 31.
To evaluate the expression, subtract 31 from 29.
Please hurry I need this answer ASAP
Answer:
The correct alternatives
This is a subtraction expression
The correct expression is n minus 31
To evaluate the expression, subtract 31 from 29.
Step-by-step explanation:
Rafael writes an expression to represent “a number, n, decreased by thirty-one.”
First you gotta know what means "decreased by thirty-one". It means that
there exist two numbers where the difference between them is 31.
The number [tex]n[/tex] decreased by 31 can be writen as
[tex]n-31[/tex]
The expression is therefore
[tex]n-x=31 \implies \boxed{x=n-31}, n, m \in \mathbb{R}[/tex]
Rafael evaluates the expression [tex](n-31)[/tex] for [tex]n=29[/tex]
[tex]n-31 = 29-31 = -2[/tex]

Step-by-step explanation:
What is the relationship between area in the scale drawing and area on the on the actual tennis court if the scale is 1in.: 5ft. and the length of the scale is 15.6 and the width is 7.2 in.
What is the ratio of areaof the actual court to the area of the drawing (as a unit rate)? Is it the same as the ratio of length of the actual court to the length of the drawing?
Given:
Length of the scale = 15.6 in.
Width of the scale = 7.2 in.
Scale of drawing = 1 in. : 5ft.
To find:
The ratio of area of the actual court to the area of the drawing (as a unit rate).
And to check whether it is the same as the ratio of length of the actual court to the length of the drawing.
Step-by-step explanation:
We have,
1 in. = 5ft.
Now, using this scale we get
15.6 in. = (15.6 × 5) ft =78 ft.
7.2 in. = (7.2 × 5) ft = 36 ft.
So, the actual length and width of tennis court are 78 ft and 36 ft respectively.
Area of actual tennis court is
[tex]Area=length\times width[/tex]
[tex]Area=78\times 36[/tex]
[tex]Area=2808\text{ ft}^2[/tex]
The area of drawing is
[tex]Area=15.6\times 7.2[/tex]
[tex]Area=112.32\text{ in.}^2[/tex]
Now, ratio of area of the actual court to the area of the drawing (as a unit rate) is
[tex]\dfrac{2808}{112.32}=\dfrac{25}{1}=25:1[/tex]
Ratio of area is 25:1 and ratio of length is 5:1 both area not same.
Therefore, the ratio of area of the actual court to the area of the drawing (as a unit rate) is 25:1.
A group of 12 students is deciding whether to go to the science center or the zoo. Science center tickets are 3 for $36.75 and zoo tickets are 4 for $51.
How much will a group of 12 students save by choosing the science center?
Enter your answer in the box.
ANSWER:
$6
ExPLANATION:
Step 1:
36.75 × 4 = 147
Step 2:
51 × 3 = 153
Step 3:
153 - 147 = 6
The group of 12 students will save $6 by visiting the science center instead of the Zoo.
Science center fee :
3 tickets = $36.75 Total cost of visiting Science center = (12/3) × 36.75 = $147Zoo Fee :
4 tickets = $51Total cost of visiting Zoo = (12/4) × 51 = $153The difference in the total amount spent :
Total cost of Zoo - Total cost of Science center $153 - $147 = $6Therefore, the group will save $6 by visiting the science center.
