Find the missing angle:
40°
?
Answer:
50
Step-by-step explanation:
180 − ( 90 + 40 )
180 − 130
50
50 degrees is the missing angle in the triangle
The given triangle is right angle triangle
One angle is 90 degrees and the other angle in the triangle is 40 degrees
We have to find the missing angle in the triangle
By angle sum property the sum of the three angles is 180 degrees in the right triangle
Let x be the missing angle
90+40+x=180
130+x=180
Subtract 130 from both sides
x=180-130
x=50 degrees
Hence, the missing angle in the triangle is 50 degrees

Factor this polynomial.
-3x² - 6x-2
Answer:
Doesn't factor
Step-by-step explanation:
We have a polynomial and are asked to factor it.
A rule I like to follow when factoring polynomials is what two numbers multiply to equal c (in this case -2) and add up to b (in this case -6x).
Since no two numbers are eligible to do this, therefore this polynomial is unfactorable.

Step-by-step explanation:
The restaurant bill you and your friend received was not itemized. You ordered 2 slices of waffles and 2 grand slams, for a total of $10.50. Your friend ordered 3 waffles and the one grand slam for $6.75.
(a) Write a system of equations for the situation. (Use w for the amount charged for a waffles and g for the amount charged for the grand slam.)
(b) Graph the equations in the system.
(c) Use your graph to estimate how much each item cost.
Answer:
Step-by-step explanation:
The system would be 2w+2g=10.50 and 3w+g=6.75 because w is waffles and g is grand slam then you need to isolate w and graph or you could use desmos if you teacher permits to graph
Michelle buys a car that costs $15,000. She makes a down payment of $5,000. If she pays $3000 in the next payment, which equation could be used to find the amount she still owes, C, of the car?
Answer: See explanation
Step-by-step explanation:
From the question, we are informed that Michelle buys a car that costs $15,000 and that she makes a down payment of $5,000 and later pays $3000 in the next payment.
To get the equation that can be used to find the amount she still owes, C, of the car, we will have to deduct the amount that she has paid from the cost of the car. This will be:
C = 15000 - 5000 - 3000
C = 15000 - 8000
Therefore solving the equation further, the amount left to pay will be:
C = 15000 - 8000
C = 7000

A total of 110 gallons of water can follow through Hose B in minutes. Which hose has a faster water ow rate, in gallons per minute, and what is that rate?
Answer:
Hose B
Step-by-step explanation:
Charles needs to fill a large fish tank with water using a hose. he has two hoses from which to choose. Water flows through each hose at a constant rate. The graph below shows the amount of water, in gallons , that flows through holes A based on the number of minutes used. A total of 110 gallons of water can flow through Hose B in 10 minutes. Which hose has a faster water rate, in gallons per minute, and what is that rate?
Solution:
The equation of a linear function is:
y = mx + b
where m is the rate of change and b is the initial value of y.
The equation of a line passing through two points [tex](x_1,y_1)\ and\ (x_2,y_2)[/tex] is given by:
[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)[/tex]
Let y represent the amount of water in gallons and let x represent the time in minutes.
For hose A, we can see that the graph passes through the point (0, 0) and (2, 12). Hence:
[tex]y-0=\frac{12-0}{2-0}(x-0) \\\\y=6x[/tex]
Therefore hose A has a flow rate of 6 gallons per minute.
110 gallons of water flow through hose B in 10 minutes. Therefore:
Flow rate of hose B = 110 gallons / 10 minutes = 11 gallons per minute
Therefore hose B has a higher flow rate

Answer:
[tex]\frac{4^{2} }{2^{2} }[/tex] = 4
(8-4)x4 = [tex]4^{2}[/tex]
[tex]2^{2} +2^{2}[/tex] = 8
Step-by-step explanation:
To solve the first one simplify the exponents and then divide them; [tex]4^{2}[/tex] equals 16 and [tex]2^{2}[/tex] equals 4. Therefore the expression is 16/4, which equals 4.
Follow PEMDAS to solve the next one. First paratheses, (8-4) equals 4. Then, multiply by 4. 4x4 can also be rewritten as [tex]4^{2}[/tex].
Simplify the exponents to solve the last expression. [tex]2^{2}[/tex] is 4, so the expression is equal to 4+4, which is 8.
The cost to rent a tube from Tubes-R-Us is $2 plus $0.50 per hour. The cost to rent a tube a tube at Rockin' River is $1 plus $0.75 per hour. After how
many hours will the cost of renting a tube at Tubes-R-Us be the same as the cost of renting a tube from Rockin' River?
Answer:
4 hours
Step-by-step explanation:
0.5 times 4 hours = 2 dollars. 2 dollars + 2 dollars = 4 dollars
0.75 times 4 = 3 dollars. 3 dollars plus 1 dollar = 4
Answer:
4 hours
Step-by-step explanation:
System of Equations:
(Tubes). c = 2 + .50h
(Rockin). c = 1 + .75h
set them equal to each other and solve for ’h’
2 + .50h = 1 + .75h
1 = .25h
h = 4

Rosa deposits $5000 in a savings account that gets compounded interest annually at a rate of 8%. If she leaves her money in the account for 2 years, how much will she have at the end of that time?
Answer:
$5318
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 4%/100 = 0.04 per year,
then, solving our equation
I = 2650 × 0.04 × 3 = 318
I = $ 318.00
The simple interest accumulated
on a principal of $ 2,650.00
at a rate of 4% per year
for 3 years is $ 318.00.
The vertices of parallelogram DEFG are E(-1,4) F(5,6) and G (8,0). Find the coordinates of D
Answer:
The coordinates of D are (2,-2)
Step-by-step explanation:
The coordinates of point D are (2,-2)
The coordinates of the parallelogram are given as:
E(-1,4), F(5,6) and G (8,0)
For the coordinates to represent a parallelogram, the following must be true
[tex]x_D - x_E = x_G - x_F[/tex]
[tex]y_D - y_E = y_G - y_F[/tex]
So, the equations become
[tex]x_D -(-1) =8-5[/tex] and
[tex]y_D -4 =0-6[/tex]
Solve for x and y in the above equations
[tex]x_D -(-1) =8-5[/tex]
[tex]x_D +1 = 3[/tex]
[tex]x_D = 3-1[/tex]
[tex]x_D = 2[/tex]
[tex]y_D -4 =0-6[/tex]
[tex]y_D - 4 = -6[/tex]
[tex]y_D = 4-6[/tex]
[tex]y_D =-2[/tex]
Hence, the coordinates of point D are (2,-2)

Which quadratic function in vertex form can be represented by the graph that has a vertex at (3, -7) and passes through the point (1, -10)?
I really need the answer QUICK please
Answer:
Answer is D
Step-by-step explanation:
(3,-7) and (1,-10) belong toD Variant
The required function is [tex]y=-\frac{3}{4}(x-3)^2-7[/tex] , so the correct option is D.
Important information:
Vertex = (3,-7)Other point = (1,-10)Quadratic function:The vertex form of a quadratic function is:
[tex]y=a(x-h)^2+k[/tex]
Where, [tex]a[/tex] is constant and [tex](h,k)[/tex] is vertex.
Substitute [tex]h=3,k=-7[/tex].
[tex]y=a(x-3)^2-7[/tex] ...(i)
Graph passes through the point (1, -10). Substitute [tex]x=1,y=-10[/tex] in (i).
[tex]-10=a(1-3)^2-7[/tex]
[tex]-10+7=4a[/tex]
[tex]-3=4a[/tex]
[tex]\dfrac{-3}{4}=a[/tex]
Substitute [tex]a=-\dfrac{3}{4}[/tex] in (i).
[tex]y=-\frac{3}{4}(x-3)^2-7[/tex]

Derrick needs to sell a minimum of 100 orders each month to make it into the sales winners circle. He has already sold 45 orders this month. He still needs to sell s more orders. Which inequality can be used to find the possible values for s? s−45>100
s−45<100 s+45≤100 s+45≥100
Answer:
s+45≥100
Step-by-step explanation:
"A minimum of" means either the same amount or more. So, the total amount he sells (s + 45) needs to be greater than or equal to 100.
