Answer:
t = 1/3
Step-by-step explanation:
for this problem we have two different shapes, what we need to do is find out the proportional relationship between the two to solve for t, lets take one of the measurements from the smaller shape, we will go with... JK at 5
now all we need to do is divide that by the larger shapes same side, in this case that would be RP at 22.5, heres what that looks like so far
5 / 22.5 = 0.2-> (the two goes on forever, normally this is represented by a line above the infinite number, this is what they call a Repeating Decimal)
ok, so now that we have the rate of change between the two shapes figured out, now we just make the same change to the last side from the same side on the first shape, wich is LK to QR as shown
1.5 * 0.2-> = 0.3->
and if 0.3 is = to 1/3, so t = 1/3
i hope this helped you out, im sorry if im a little late lol, make note that all of this can be applied to similar situations, just figure out the change(s) that happened from one shape to the other, and make that same change on the unknown side or area
take care :D
Write the Quadratic Formula for the quadratic equation.
Answer:
[tex]x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}[/tex]
Step-by-step explanation:
Hello!
Let's start with the given equation and work our way towards x.
Solve for x[tex]ax^2 + bx + c = 0[/tex]Divide both sides by a
[tex]a(x^2 + \frac bax + \frac ca) = 0[/tex] [tex]x^2 + \frac bax + \frac ca = 0[/tex]Move c/a to the other side
[tex]x^2 + \frac bax = -\frac ca[/tex]At the step, we have to use the Completing the Square method.
[tex]x^2 + \frac bax + (\frac{b}{2a})^2 = -\frac ca + (\frac b{2a})^2[/tex][tex]x^2 + \frac bax + \frac{b^2}{4a^2} = -\frac ca + \frac {b^2}{4a^2}[/tex][tex](x + \frac b{2a})^2= -\frac ca + \frac{b^2}{4a^2}[/tex]Multiply -c/a by 4a and add the two fractions
[tex](x + \frac b{2a})^2= \frac{b^2 - 4ac}{4a^2}[/tex]Square Root both sides
[tex]\sqrt{(x + \frac b{2a})^2}= \sqrt{\frac{b^2 - 4ac}{4a^2}}[/tex][tex]x + \frac b{2a} = \pm\frac{\sqrt{b^2 - 4ac}}{2a}}[/tex]Subtract b/2a
[tex]x = \pm \frac{ \sqrt{b^2 - 4ac}}{2a} - \frac b{2a}[/tex][tex]x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}[/tex]And that's the derivation of the Quadratic Formula.

Find the value of x.
Answer:
50
Step-by-step explanation:
The upper left hand arc is also 130
The lower right hand arc is also x
A circle all the way around from some starting point is 360 degrees.
x + x + 130 + 130 = 360 Equation. Combine like terms.
2x + 260 = 360 Subtract 260 from both sides
2x = 360 - 260
2x = 100 Divide by 2
x = 100/2
x = 50

A TV has a listed price of $711.95 before tax. If the sales tax rate is 8.75%, find the total cost of the TV with sales tax
included.
Round your answer to the nearest cent, as necessary.
HELP I WILL MARK BRAINLIEST JUST PLEASE
Answer:
774.25
Step-by-step explanation:
8.75 becomes .0875 because it is 8.75%/100%
711.95 x .0875 = 62.295625
add the cost (711.95) and the tax (62.295625)
711.95 + 62.295625 = 774.245625
rounded = 774.25
Help! Find the domain of the graph
Answer:
[-8,4]
Step-by-step explanation:
you look at the x-axis. The end points of the graph are -8 and 4, thus the domain would be [-8,4] as it is always written in left to right or bottom to top value.

$750 at 6% for 18 months
Answer:
The interest is $1242.734 and the amount is $13242.734.
Step-by-step explanation:
STEP 1: Convert interest rate of 1.5% per month into rate per year.
STEP 2: Convert 210 days into years.
STEP 3: Find an interest by using the formula , where I is interest, P is total principal, i is rate of interest per year, and t is total time in years.
In this example P = $12000, i = 18% and t = 0.57534 years, so
STEP 4: Find an amount by using the formula .
Since P = $12000 and I = $1242.734 we have

Answer:
C. 244°Step-by-step explanation:
Angle formed by two tangents is equal to half of the difference of intercepted arcs:
m∠C = 1/2(arcAXB - arcAB)64° = 1/2(mAXB - mAB)mAXB - mAB = 128°The sum of the same two arcs is a full circle:
mAXB + mAB = 360°Add the two equations together:
2mAXB = 360° + 128°2mAXB = 488°mAXB = 244°Correct choice is C

The measure of angle ABD is (0.15x+65) and the measure of angle CBD is(0.1x+28) . Find the value of x.
Answer:
x = 348
Step-by-step explanation:
The measure of angle ABD is (0.15x+65) and the measure of angle CBD is(0.1x+28) . Find the value of x.
0.15x + 65 + 0.1x + 28 = 180
0.25x + 93 = 180
0.25x = 180 - 93
0.25x = 87
x = 87/0.25
x = 348
2 of 7 A shop has a sale of 5% off all items in stock. If the original price of a dress is £80 what would be its sale price?
Answer:
the sale price is £76
Step-by-step explanation:
The computation of the sale price is shown below:
= Original price - original price × off percentage
= £80 - £80 × 5%
= £80 - £4
= £76
Hence, the sale price is £76

Ο Ο
4 - Purple
O
None
Answer: None
Step-by-step explanation:
angle APD would suggest that P is the vertex (where the rays of the angle originate) and A and D would be the rays that extend outward from the vertex forming an angle. This angle is not marked on the diagram.

Step-by-step explanation:
how do we add fractions
Answer:
you have to find a common denominator and then add.
Step-by-step explanation:
for example 2/4 + 4/12
you find the common denominator in this case it would be i will use 4 so 2/4 would stay the same and 4/12 would change to 1/3
*make sure to do the same thing to the numerator to so if you are dividing your denominator by 2 also do the numerator
now you have to add
2/4 + 4/12 = 6/12 (the denominator stays the same)
6/12 can be simplified (if you are asked to simplify) so it is 1/6
