Answer:
EF ≈ 1.98
Step-by-step explanation:
Using the sine ratio in the right triangle
sin26° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{EF}{FD}[/tex] = [tex]\frac{EF}{4.5 }[/tex] ( multiply both sides by 4.5 )
4.5 × sin26° = EF
4.5 × 0.44 = EF , that is
EF ≈ 1.98 ( to 2 dec. places )

find the value of x so that f(x)=7.
find the value of x so that f(x)=7
The answer is:
x = 5
The value of x such that f(x) = 7 is 5.
What is Function?A function is a relation from a set A to a set B where the elements in set A only maps to one and only one image in set B. No elements in set A has more than one image in set B.
Given a graph of a function f(x).
The graph is a straight line where there is a unique value of y for each value of x.
We have to calculate the value of x when y = 7.
Taking the y coordinate to 7, the x coordinate corresponding to the y coordinate is 5.
Hence the value of x is 5.

Solve 2/3x- 1/5>1
Answer:
x > 9/5
Step-by-step explanation:
Step 1: Write inequality
2/3x - 1/5 > 1
Step 2: Solve for x
Add 1/5 to both sides: 2/3x > 6/5Divide both sides by 2/3: x > 9/5Here we see that any x value greater than 9/5 will work.

There are two twins. One twin wants to explore the planet near Proxima Centauri and leaves on a spaceship traveling at 90% of the speed of light, while the other twin stays home on Earth. How much does the twin on Earth age while the other twin travels to Proxima Centauri?
Answer:
4.7 years
Step-by-step explanation:
Distance of planet from Earth = 1.3 parsec
We know that 1 parsec = 3.26 light years
And a light year is the distance traveled by light in time period of 1 year.
So, Distance of planet from Earth = 1.3 [tex]\times[/tex] 3.26 = 4.24 light years
Given that, the person travels at a speed equal to 90% of the light speed.
To travel to the planet from Earth, Light takes 4.24 years.
To travel the distance [tex]D[/tex], at a speed [tex]s[/tex] light takes time of 4.24 years.
To travel the distance [tex]D[/tex], at a speed [tex]0.90s[/tex], the person takes time:
[tex]\dfrac{4.24}{0.90} = \bold{4.7\ years}[/tex]
So, the twin on Earth ages by 4.7 years.
Answer:

The temperature in Coldspot is -7o F and increasing 2.5o per hour. The temperature in Frostberg is 19 degrees F and decreasing 4 degrees per hour.
a. How long will it be until the temperatures are the same?
b. What will the temperature be then?
Answer:
It will take 4 hours for the temperatures to be the same. The temperature will be 3° at that time.
Step-by-step explanation:
Coldspot = -7 + 2.5x
Frostberg = 19 - 4x
First, we are going to input our values into the variable in a table.
Coldspot Frostberg
1 -7 + 2.5(1) = -4.5 19 - 4(1) = 15
2 -7 + 2.5(2) = -2 19 - 4(2) = 11
3 -7 + 2.5(3) = 0.5 19 - 4(3) = 7
4 -7 + 2.5(4) = 3 19 - 4(4) = 3
It will take 4 hours for the temperatures to be the same. The temperature will be 3° at that time.

Jeremy is saving $250 per month for his vacation . How much will Jeremy save up for his vacation in 1 year and 6 months?
Answer:
The expression shows the number of dollars he will have saved by the end of the year is given by 35(7)+40(5)=\$44535(7)+40(5)=$445
Step-by-step explanation:
Since we have given that
Amount he saved per month over the first 7 months = $35
Amount he saved per month over the next 5 months = $40
So, total saving by the end of the year is given by
\begin{gathered}35\times 7+40\times 5\\\\=\$245+\$200\\\\=\$445\end{gathered}
35×7+40×5
=$245+$200
=$445
Hence, the expression shows the number of dollars he will have saved by the end of the year is given by
35(7)+40(5)=\$44535(7)+40(5)=$445
A deluxe bakery sells a cookie for $2.38, a brownie for $3.07 and a cake for $14.87. On Wednesday they sold 13 cookies, 4 brownies and 4 cakes. The cost in ingredients for each cookie is $1.7, for each brownie is $1.91 and for each cake is $5.83. How much profit did they make on Wednesday?
Answer:
$ 49.64
Step-by-step explanation:
Selling price of cookie on Wednesday = 13 × 2.38 = $30.94
Selling price for brownie on Wednesday = 4 × 3.07 = $ 12.28
Selling price for cakes on Wednesday = 4 × 14.87 = $ 59.48
Cost price for cookie = 13 × 1.7 = $ 22.1
Cost price for brownie = 4 × 1.91 = $ 7.64
Cost price for cakes = 4 × 5.83 =$ 23.32
Total profit for Wednesday= Total selling price - total cost price
That is;
(30.94 + 12.28 + 59.48) - (22.1 + 7.64 +23.32) = $ 49.64
