Answer:
Step-by-step explanation:
Let <ADB be x. From the rectangle, <ADB+<BDC = <ADC
<ADB+<BDC = 90° ..... 1
If angle BDC is 31° greater than mangle ADB, then <BDC = x+31
Substituting the given values into the equation 1:
x+x+31 = 90
2x + 31 = 90
2x = 90-31
2x = 59
x = 59/2
x = 29.5°
To get <BDC, we will substitute x = 29.5° into the expression <BDC = x+31
<BDC = 29.5+31
<BDC = 60.5°
Hence <ADB = 29.5° and <BDC = 60.5°

On Monday, your bank account balance was -$12.95. Because you didn't realize this, you wrote a check for
$30.93 for groceries.
What is the new balance in your checking account?
Answer:
Your new balance in your checking account would be -$43.88.
Step-by-step explanation:
You can solve this by starting with -$12.95 and subtracting $30.93. You do this because you wrote a check for $30.93 and you didn't have the money, so your balance in your banking account would still be in the negatives.
Answer:
$-43.88
Step-by-step explanation:
You start with a balance of:
[tex]-12.95[/tex]
You then wrote a check, meaning money has been spent, so we will have to subtract the check total from your bank account balance:
[tex]-12.95-30.93[/tex]
Solve:
[tex]-43.88[/tex]

What is the distance between the points A(-5, 3) and B(4, -1)? *
Answer:
[tex]\sqrt{97}[/tex] units
Step-by-step explanation:
Calculate the distance using the distance formula
d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]
with (x₁, y₁ ) = A(- 5, 3) and (x₂, y₂ ) = B(4, - 1)
d= [tex]\sqrt{(4+5)^2+(-1-3)^2}[/tex]
= [tex]\sqrt{9^2+(-4)^2}[/tex]
= [tex]\sqrt{81+16}[/tex]
= [tex]\sqrt{97}[/tex] ≈ 9.85 ( to 2 dec. places )

An electrician has a 20-ft wire. He needs to cut the wire so that one piece is 4 ft shorter than the other. What will be the length of each piece?
Answer:
12, 8
Step-by-step explanation:
So we have the following things we need to check for:
1. Both wires add up to 20 ft.
2. One wire is 4 ft longer than the other.
In order to do this we can create the following two equations (I'll call the wires a and b)
[tex]a + b = 20\\a = b - 4[/tex]
Next we substitute equation two into equation one and solve for b.
[tex]a + b = 20\\ (b - 4) + b = 20\\ 2b - 4 = 20\\2b - 4 + 4 = 20 + 4\\2b = 24[/tex]
[tex]\frac{2b}{2} = \frac{24}{2}\\b = 12[/tex]
And lastly we solve equation 2 using the new value of b.
[tex]a = b - 4 = 12 - 4 = 8[/tex]
So the wires are 12 and 8 feet.
Find the vertex of the function given below
[tex]y = {x}^{2} - 6x + 1[/tex]
Answer:
3,-10...........................
Answer:
vertex = (3, - 8 )
Step-by-step explanation:
Given a parabola in standard form
y = ax² + bx + c ( a ≠ 0 )
Then the x- coordinate of the vertex is
[tex]x_{vertex}[/tex] = - [tex]\frac{b}{2a}[/tex]
y = x² - 6x + 1 ← is in standard form
with a = 1 and b = - 6 , thus
[tex]x_{vertex}[/tex] = - [tex]\frac{-6}{2}[/tex] = 3
Substitute x = 3 into the function for y
y = 3² - 6(3) + 1 = 9 - 18 + 1 = - 8
vertex = (3, - 8 )

what is the slope of the line?
Answer:
1/2
Step-by-step explanation:
Hope this helps:)
Answer:
1/2 simplified
Step-by-step explanation:
You do rise over run. That means you count up from the (-2, -1) point then get level with the other point (2, 1) And that should give a right triangle. Then count how many boxes are going up put that number on top. Then count how many boxes are going across and that number goes on bottom. You then get 2/4, but I simplified it to 1/2.
Also you can do...
[tex]\frac{y2 - y1}{x2 - x1}[/tex] plug in
[tex]\frac{1 + 1}{2 + 2}[/tex] = [tex]\frac{2}{4}[/tex]
The reason I added because it was 1 - - 1 or one minus negative 1 so two negatives make a positive same thing with the bottom it was 2 - - 2.

During a cat food sale, a pet store sells 220 cans of cat food. At the end of the
sale, the store has 80% of the original number of cans of cat food. How many
cans of cat food are left?
Answer:
44 cans
Step-by-step explanation:
To find 80%, just multiply 220 by 0.8
220 x 0.8 = 176.
Now, take 220 and subtract 176.
220-176 = 44
44 cans are left over. Hope this helps.

The gravity on the surface of the moon is 0.17 of the surface gravity on Earth. If Jack weighs 156 pounds on Earth, what would be his weight on the moon? (Will give brainliest)
Answer:
Jack will weigh 26.52 pounds
Step-by-step explanation:
x = 156 (Your weight on Earth)
y = 0.17 (Surface Gravity)
z = Your weight on the moon
x * y = z
156 * 0.17 = 26.52
Jack will weigh 26.52 pounds.
If Jack weighs 156 pounds on Earth his weight on the moon will be 26.52 pounds.
What is gravitational force?All mass-bearing objects are attracted by gravitational force. Because it consistently attempts to bring masses together rather than push them apart, the gravitational force is referred to as attractive.
It is given that,
Gravity on the surface of the moon = 0.17
Weighs of Jack on Earth = 156 pounds
Mass of Jack,
W=mg
156 pounds = m × 9.81 [ g on earth = 9.81 m/s²]
m = 15.902 kg
The weight of Jack on the moon is,
W= 15.902 kg × 0.17
W=2.565 N
Thus, if Jack weighs 156 pounds on Earth his weight on the moon will be 26.52 pounds.

A one-year membership to a gym costs $725. The registration fee is $125, and the remaining amount is paid monthly. Define a variable. Then write and solve an equation to find how much new members pay each month NEEDS WORK please help i'm in the middle of a quiz nd i'm so gonna fail
Given :
A one-year membership to a gym costs $725.
The registration fee is $125.
To Find :
How much new members pay each month.
Solution :
Remaining fee = Total fee - Registration fee
R = $( 725 - 125 )
R = $600
Amount of fee paid monthly is :
[tex]C=\dfrac{R}{12}\\\\C = \dfrac{600}{12}\\\\C = \$50[/tex]
Therefore, monthly fee is $50.
Hence, this is the required solution.
