3. Triangle ABC has angle measures as shown.
(a) What is the value of x? Show your work.
The value of x is 13°.
Solution:
In triangle, sum of all the interior angles = 180°
m∠A + m∠B + m∠C = 180°
(3x)° + (4x – 1)° + 90° = 180°
3x° + 4x° – 1° + 90° = 180°
7x° + 89° = 180°
Subtract 89° from both sides of the equation, we get
7x° = 91°
Divide by 7 from both sides of the equation, we get
x° = 13°
The value of x is 13°.
Find two consecutive whole numbers that √92 lies between.
Answer:
9 and 10
Step-by-step explanation:
Consider perfect squares on either side of 92, that is
81 < 92 < 100, thus
[tex]\sqrt{81}[/tex] < [tex]\sqrt{92}[/tex] < [tex]\sqrt{100}[/tex], that is
9 < [tex]\sqrt{92}[/tex] < 10
Final answer:
To find two consecutive whole numbers that the square root of 92 lies between, we calculate the square root of 92 to determine its approximate value, which falls between 9 and 10.
Explanation:
To find two consecutive whole numbers that √92 lies between, we need to calculate √92 to determine its approximate value. Since 92 is between 81 (9²) and 100 (10²), the square root of 92 lies between 9 and 10. Therefore, the consecutive whole numbers are 9 and 10.

coach currans team has won 5 times and lost 2 times.He hopes that his team can keep this same ratio of wins to losses.If the team has 10 losses,how many wins would they need to keep the record
Answer:
The answer is that the team has to have 25 wins.
Step-by-step explanation:
since the ratio is 2 losses to 5 wins, if you divide 10 by 2, you get 5. Multiply 5 by 5, since it is the other side of the ration, and you'll get 25 wins.

The function f is defined by f(x) = x2 - 6x +21.
What are the solutions of f(x) = 0?
Show your work on the scratchpad.
The solutions are:
[tex]x =3+2\sqrt{3}i\\\\\:x=3-2\sqrt{3}i[/tex]
Solution:
[tex]f(x) = x^2 - 6x + 21[/tex]
We have to find solutions when f(x) = 0
[tex]x^2 - 6x + 21 = 0[/tex]
Solve by quadratic formula
[tex]\mathrm{For\:a\:quadratic\:equation\:of\:the\:form\:}ax^2+bx+c=0\mathrm{\:the\:solutions\:are\:}\\\\x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}\\\\\mathrm{For\:}\quad a=1,\:b=-6,\:c=21\\\\x=\frac{-\left(-6\right)\pm \sqrt{\left(-6\right)^2-4\cdot \:1\cdot \:21}}{2\cdot \:1}[/tex]
[tex]x = \frac{6 \pm \sqrt{\left(-6\right)^2-4\cdot \:1\cdot \:21}}{2\cdot \:1}\\\\Simplify\\\\x = \frac{6 \pm \sqrt{36 - 84}}{2}\\\\x = \frac{6 \pm \sqrt{-48}}{2}\\\\x = \frac{6 \pm i \sqrt{48}}{2}\\\\simplify\\\\x = \frac{6 \pm 4\sqrt{3}i}{2}\\[/tex]
[tex]x = 3 \pm 2 \sqrt{3} i[/tex]
We have two solutions:
[tex]x = 3 + 2 \sqrt{3} i\\\\x = 3 - 2 \sqrt{3} i[/tex]
Thus the solutions are:
[tex]x =3+2\sqrt{3}i\\\\\:x=3-2\sqrt{3}i[/tex]

So , it's correct ordered pair .
(2,9):
⇒ [tex]y = 7x-5[/tex]
⇒ [tex]y = 7(2)-5[/tex]
⇒ [tex]y =9[/tex]
So , it's correct ordered pair .
(-3,-26):
⇒ [tex]y = 7x-5[/tex]
⇒ [tex]y = 7(-3)-5[/tex]
⇒ [tex]y =-26[/tex]
So , it's correct ordered pair .
Therefore, option c {(0, -5), (2,9), (-3, -26)} is correct . All others doesn't satisfy the equation .

Use the function below to find F(2).
F(t) = 2•1/2^3t
Answer:
[tex]F(2)= \frac{1}{32} [/tex]
Step-by-step explanation:
The given function is
[tex]F(t) = 2 \cdot \: \frac{1}{{2}^{3t} } [/tex]
To find F(2), we substitute t=2 into the function.
This means that wherever we see t, we put 2
[tex]F(2) = 2 \cdot \: \frac{1}{{2}^{3 \times 2} } [/tex]
We multiply the exponent in the denominator to get:
[tex]F(2) = 2 \cdot \: \frac{1}{{2}^{6} } [/tex]
We evaluate to get:
[tex]F(2) = 2 \cdot \: \frac{1}{64} [/tex]
We now cancel the common factors to get:
[tex]F(2) = \frac{1}{32} [/tex]
A certain shade of paint is made by mixing 5 parts of blue paint with 2 parts of white paint. To get the correct shade, how many quarts of white paint should be mixed with 8.5 quarts of blue paint?
Answer:
6.8 quarts of white paint
Step-by-step explanation:
If you make 5 parts equal to 0.5 you will have 17 parts blue paint. 17 divided by 5 (to get how many parts we are using) is 3.4. One part blue paint is 3.4 quarts. Times that by two to get how many parts of white paint. We need 6.8 quarts of white paint.
Ellen bought a new computer tablet for $460. She paid $100 at the time of purchase and will make monthly payments of $45 to finish paying for the tablet. She used the equation to determine the number of months (m) she needs to make payments. For how many months will she make payments?
Please help this is urgent!
Answer:
The answer is 8 months
Step-by-step explanation:
The new computer tablet is $460. She paid $100 at the time so I subtracted $100 from $460, which equals to $360. The monthly payments are $45 a month, so I divided $360 by $45, which equals 8. It takes 8 more months to finish the payment.

On a fishing trip, Mariko caught 24 fish. She caught some rockfish averaging 2.5lbs and some bluefish averaging 8lb. The total weight of the fish was 137lbs how may of each fish did she catch.
Mariko caught 10 rockfish and 14 bluefish on her fishing trip.
Explanation:Let's define the number of rockfish caught as x and the number of bluefish caught as y.
According to the given information, the average weight of each rockfish is 2.5lbs and the average weight of each bluefish is 8lbs.
We can form two equations based on the total weight of all the fish and the total number of fish caught:
Equation 1: x + y = 24 (since Mariko caught a total of 24 fish)Equation 2: 2.5x + 8y = 137 (since the total weight of the fish was 137lbs)We can solve this system of equations to find the values of x and y by either substitution or elimination method. Using the elimination method:
Multiplying Equation 1 by 2.5, we get 2.5x + 2.5y = 60
Subtracting this equation from Equation 2, we get 8y - 2.5y = 137 - 60
Simplifying, we have 5.5y = 77
Dividing both sides by 5.5, we get y = 14
Substituting this value back into Equation 1, we have x + 14 = 24
Simplifying, we get x = 10
Therefore, Mariko caught 10 rockfish and 14 bluefish.
An orange has 20 fewer calories
than a banana. If 7 bananas have
the same number of calories as 9
oranges, how many calones are in a
banana?
Answer:
90 calories in total
Step-by-step explanation:
We can solve this equation through the following steps:
Step One: Since we are told that a banana is 20 less calories than an orange, we can create the Let Statements:
Let x= the calories in a banana
Let x-20=the calories in an orange
Step Two: Create an equation
Since we are told "7 bananas have the same calories as 9 oranges" we translate"
7x=9(x-20) Distribute
7x=9x-180 Subtract 9x from both sides of the equation
7x-9x=-180 Simplify
-2x=180 Divide both sides by -2
x=90
∴There are 90 calories in a banana.

Are 3/4 and 7/8 equivalent
Answer:
No.
Step-by-step explanation:
3/4 cannot be simplified. Neither can 7/8. Also, 3/4 as a decimal is 0.75, and 7/8 as a decimal is 0.875.
Answer:
No
Step-by-step explanation:
Is 3/4 less than 7/8? Is 3/4 smaller than 7/8? These are the same questions with one answer.
To get the answer, we first convert each fraction into decimal numbers. We do this by dividing the numerator by the denominator for each fraction as illustrated below:
3/4 = 0.75
7/8 = 0.875
Then, we compare the two decimal numbers to get the answer.
0.75 is less than 0.875.
Therefore, 3/4 is less than 7/8 and the answer to the question "Is 3/4 less than 7/8?" is yes.

Answer:
y = -3/4x + 5
Step-by-step explanation:
Slope intercept form is y=mx + b
First, find the slope of the line. the points are (0,5) and (4,2), as marked. To find the slope, you do (y2-y1)/(x2-x1). Fill in the numbers and you get
(2-5)/(4-0). Simplify and you get -3/4 is the slope. Then, to find b, you have to fill in one coordinate pair and the slope into y=mx+b. So, I used (0,5).
5=(-3/4)(0) + b
Then you get 5=b by solving, and you fill in the slope and the y intercept in the slope intercept form equation. y = -3/4x +5. This is how you find the answer.

at current prices, roberta can drive her car 8.2 miles per dollar of gasoline that she buys. Roberta and three of her friends decide to go on a road trip to a neighboring university that is 105 miles away and agree to split the cost evenly . to the nearest cent, how much money will each have to contribute to get to the university and back?
Answer:
I think it's $12.80 but I might be wrong.
Each person will have to contribute $6.40.
Explanation:To find out how much money each person will have to contribute to get to the university and back, we can first find the total cost of the trip. The distance to the university and back is 2 times the distance to the university, which is 105 miles. So the total distance is 2 * 105 = 210 miles. Roberta's car can travel 8.2 miles per dollar of gasoline, so the total cost of the trip is 210 / 8.2 = 25.61 dollars. Since Roberta and three friends are splitting the cost evenly, each person will have to contribute 25.61 / 4 = 6.4025 dollars. Rounding to the nearest cent, each person will have to contribute $6.40.
