A sailboat has a mast that holds a triangular sail.The sail has a base of twelve meters and a height of nine meters. The cost of the sail is $15 per square meter. What will it cost to make the sail?

Answers

Answer 1

Answer: First since it is a triangle and it says meter square that means its an area
so the area is 1/2hb h stands for height and b stands for base
so
a=1/2bh
a=1/2(12)(9)
a=1/2(108)
a=54m^2

It says the cost of sail is $15 per square meter
so
$15*54
=$810

Why times by 54 because if 1 piece is $15 how about 54pcs?
thats why we will multiply it

answer:
5c+4=2(c-5)
opening the parentheses we get:
5c+4=2c-10
putting like terms together we get
5c-2c=-10-4
3c=-14
c=-14/3

so the answer would be A. C = - 4 2/3

Which of the following is a zero for the function f(x) = (x − 15)(x + 1)(x − 10)?X=-15
X=-10
X=1
X=15

Answers

we have the function

$f(x)=(x-15)(x+1)(x-10)$

we know that

The zero's of the function are the values of variable x when the value of the function is equal to zero

in the given function the zero's are

$x=15\nx=-1\nx=10$

therefore

the answer is

$x=15$

The answer should be x=15 because once u subtract 15-15 u get 0 and then u substitute 15 in "x" and then. Multiply 0 by everything else n u get 0:))

Use inverse operation to solve 116=4n

Answers

Just divide by 4 on both sides to isolate n, that gets you 29.

Answer: 29

Step-by-step explanation:

116=4n

(Divid both sides by 4)

29=n

Answers

Part 1: Keisha ran to swim practice but needed to stop by her friend Natasha’s house on the way. She stayed at Natasha’s house for 15 minutes, and together they ran the rest of the way to practice, where they stayed for 1 hour.

If we graph this there will be 3 segments because the slope of each segment is Keisha's speed during that interval:

⇒ The middle segment will have no slope,which makes the slope undefined.

⇒ The 1st and 3rd segments will have positive slopes, If a line has a positive slope, variable y always increases when x increases.

Choice A). A coordinate plane graph is shown. The axis is labeled time and the y-axis is labeled distance from home in blocks. A line begins at 0 comma 5, decreases to 0.25 comma 2, stays horizontal to 0.6 comma 2, then increases to 0.75 comma 9. The line is horizontal to 1.75 comma 9.

The given graph started that the time is 0, when Keisha begins
running. she is already 5 blocks from home. So this data is incorrect. The graph also states that the line decreases,when she runs toward her home.

Terrible choice.

Choice B). A coordinate plane graph is shown. The axis is labeled time and the y-axis is labeled distance from home in blocks. A line begins at 0 comma 0, increases to 0.3 comma 2, increases to 0.5 comma 5, then increases to 0.75 comma 9. The line decreases to 1.75 comma 0, where it touches the axis.

Terrible choice.

Choice C). This is the correct answer. It includes all the information that appears on the given graph, and it matches the given story.

Choice D). A coordinate plane graph is shown. The axis is labeled time and the y-axis is labeled distance from home in blocks. A line begins at 0 comma 5, is horizontal to 0.3 comma 5, increases to 0.5 comma 6, is horizontal to 0.8 comma 6, then increases to 1.75 comma 9

Terrible choice.

Part 2 : Sasha withdrew spending money. Meaning : To remove (money) from an account.

The correct answer is the last one.

Q1:
Answer:
A coordinate plane graph is shown. The x-axis is labeled time and the y-axis is labeled distance from home in blocks. A line begins at 0 comma 0, increases to 0.25 comma 5, stays horizontal until 0.5 comma 5, then increases to 0.75 comma 9. The line is horizontal until 1.75 comma 9.

Explanation:
First segment: distance and time increases (Keisha ran to Natasha's house)
Second segment: time increases, distance is constans (Keisha stayed at Natasha’s house)
Third segment: distance and time increases (Keisha and Natasha ran to swim practice)
Fourth segment: distance is constans, time increases (Keisha and Natasha stayed on practice).

Sasha did not withdraw or deposit any money. (During 5 days of the account balance has not changed).
