In right triangle DEF, ∠E is a right angle, m∠D=26∘, and DF=4.5.

What is the measurement of EF?
If necessary, round your answer to two decimal places, like this: 42.53
Answer:
EF = 1.98
Step-by-step explanation:
Sin = opposite/hypotenuse; Cos = adjacent/hypotenuse ;
Tan = opposite/adjacent
DF = 4.5 which is the hypotenuse. So using the equation for Sin
Sin 26° = opposite/hypotenuse
Sin 26° = EF/4.5
.44 = EF/4.5 solving .44(4.5) = EF ; 1.98 = EF
Approximate the value of 44 squared to the nearest hundredth
Step-by-step explanation:
176
to th nearest hundredth is 100

Charlotte buys a ticket to go to a baseball game. The total includes a charge of 7% of the original price for extra fees. If Charlotte pays a total of $44.94, how much was the original price of the ticket?
Answer:
$41.7942
Step-by-step explanation:
First you need to change 7% into a decimal (you do this by dividing it by 100)
7÷100=0.07
Then, you multiply 0.07 with 44.94
0.07×44.94=3.1458
3.1458 is the amount for the extra fees.
After that, you subtract 44.94 with 3.1458
44.94-3.1458=41.7942
This gives us the original price, so, the original price is $41.7942.
Write each equation in slope-intercept form. Under line the slope and circle the y-intercept in each equation.
5x+3y=30
This is one RSM
The y-intercept is (_,_)
Answer:
y = -5/3(x) + 10
Step-by-step explanation:
Slope intercept form is in the form of y = mx + b
M is the slope and b is the y-intercept.
We want to isolate the y in this equation so we subtract both sides by 5x and get.
3y = -5x + 30
Now we can divide both sides by three to leave y by itself.
y = -5/3(x) + 10

Determine the relationship between the two triangles and whether or not they can be proven to be congruent. what's the relationship
Answer:
ASA
Step-by-step explanation:
Look at both triangles.There is one side of each triangle given same Two adjacent angles to those sides are congruent.So bith triangles are congruent by Angle-side-Angle congruencyAnswer:
AASStep-by-step explanation:
We can observe two angles and a non-included side are congruent.
This is called AAS congruence
If two angles and the non-included side of one triangle are equal to the corresponding angles and side of another triangle, the triangles are congruent.1. How many triangles are created in the following situation:
Answer:
Step-by-step explanation:
We can use:
[tex]\frac{12}{sin35} = \frac{16}{sinB}[/tex]
Solve for sinB
[tex]sinB=\frac{16(sin35)}{12}[/tex]
The answer we get from that is: 0.76
With that answer, we can do:
[tex]B=sinx^{-1}(0.76)[/tex]
So, since the calculator did NOT put out an error, there is 2 such triangles.
Only 1 triangle can be formed by angle m∡A = 35°, a = 12, b = 16.
How many triangles are created in the following situation:m∡A = 35°, a = 12, b = 16. is to be determined.
The triangle is a geometric shape that includes 3 sides and the sum of the interior angle should not be greater than 180°.
Here, the data given is m∡A = 35°, a = 12, b = 16,
Since one angle m∡A = 35° is given between the two sides a = 12, b = 16,.
There is only one triangle that can be made through the given data.
because when we plot the measures only one side can be added without calculation in order to complete the triangle.
Thus, only 1 triangle can be formed by m∡A = 35°, a = 12, b = 16.

Please help me with please solving for x and y
Step-by-step explanation:
Solving for x7x + 30 = 11x - 24
30 + 24 = 11 - 7x
54 = 4x
54/4 = x
27/2 = x
13.5 = x
Solving for y5y + 38 = 17y - 4
38 + 4 = 17y - 5y
42 = 12y
42/12 = y
21/6 = y
7/2 = y

find the number which when divided by 2/5 will give 30
Answer:
The answer is 12. 12 divided by 2/5 will give us 30.
Step-by-step explanation:
To find this, simply do the opposite of dividing. Simply multiply 2/5 by 30, and you'll have your answer.
First, before we do this, however, we are going to find out what the decimal form of 2/5 is. To do this, divide the numerator by the denominator. In this case, 2 is the numerator and 5 is the denominator. So divide 2 by 5.
This gives us 0.4. So 2/5 in decimal form is 0.4. Now multiply 0.4 by 30 to find your answer.
30*0.4=12
So the answer is 12. However, rememeber that you always need to check your work. So lets check.
12/30=0.4
0.4=0.4
Do we get a true statement? Yes, so we are correct.
The number you are looking for is 75.
To find the number that, when divided by 2/5, gives 30, we can set up the following equation:
x / (2/5) = 30
To solve this equation, we can multiply both sides of the equation by the reciprocal of 2/5, which is 5/2:
x = 30(5/2)
Simplifying the right side of the equation:
x = 150/2
Dividing 150 by 2:
x = 75
Therefore, the number you are looking for is 75.

2t/t-5 + 1/t-3 = 3 Help..
Step-by-step explanation:
Given equation is 2t/(t-5) + 1/(t-3) = 3
=> [2t(t-3)+1(t-5)]/(t-5)(t-3) = 3
=> (2t²-6t+t-5)/(t²-5t-3t+15) = 3
=> (2t²-5t-5)/(t²-8t+15) = 3
=> 2t²-5t-5 = 3(t²-8t+15)
=> 2t²-5t-5 = 3t²-24t+45
=>3t²-24t+45-2t²+5t+5 = 0
=> t²-19t+50 = 0
The standard form is t²-19t+50 = 0

Answer:
y = 1/7x -16/7
Step-by-step explanation:
We can point slope form
y-y1 = m(x-x1) where m is the slope and (x1,y1) is a point on the line
y - -2 = 1/7(x-2)
y+2 = 1/7(x-2)
Distribute
y+2 = 1/7x - 2/7
Subtract 2 from each side
y+2-2 = 1/7x -2/7-2
y = 1/7x -2/7 - 14/7
y = 1/7x -16/7

Answer:
The domain is [0,25] and the range is [0,20]
Step-by-step explanation:
The domain is the range of numbers and that the x value can be in the graph. The range is the range of numbers that the y value can be in the graph.
For the domain, the lowest x value you have is zero in the biggest x value is 25. since there is a dot when x is 25 and when x is 0 your answer is in brackets.
For the range, the lowest y value is 0 and the highest y value is 20. once again your answer is in brackets because there is a point when y is 0 and when y is 20.
