find QR. help please and thank you<3
Answer:
QR = 1.3
Step-by-step explanation:
Sides TQ and TS are congruent, thus Δ QST is isosceles.
RT is a perpendicular bisector, that is it bisects QS at right angles, thus
QR = RS = 1.3
The measure of length of QR is 1.3 units.
What is an isosceles triangle?Isosceles triangles are those triangles that have at least two sides of equal measure and two base angles are equal.
In the given triangle TQS, QT=TS=4.7 units, so triangle TQS, isosceles triangle.
In isosceles triangle TQS, TR is the perpendicular bisector.
Then QR=RS= 1.3 units
Therefore, the measure of length of QR is 1.3 units.

what is the formula for finding missing angles of a triangle
Answer:
Now that you are certain all triangles have interior angles adding to 180° , you can quickly calculate the missing measurement. You can do this one of two ways: Subtract the two known angles from 180° . Plug the two angles into the formula and use algebra: a + b + c = 180°

Answer:
Huh!
The circles with of same radii or same circumference or same area are congruent.
No need to proof!
Step-by-step explanation:
Or just type it,
'Since they have the same radii, they are congruent!'
The two given circles are congruent as their radius are similar.
What is a circle?All points in a plane that are at a specific distance from a specific point, the center, form a circle. In other words, it is the curve that a moving point in a plane draws to keep its distance from a specific point constant.A circle is a closed, two-dimensional object where every point in the plane is equally spaced from a central point. The line of reflection symmetry is formed by all lines that traverse the circle. Additionally, every angle has rotational symmetry around the center.So, the two circles are congruent because:
We know that:
AB = CDAnd AB and CD are the two radius of the given two circles.Since their radius is similar.So, the two circles will be congruent.
Therefore, the two given circles are congruent as their radius are similar.

Margo can purchase tile at a store for $.99 per tile and rent a tile saw for $10. At another store she can borrow the tile saw for free if she buys tiles there for $1.49 per tile. How many tiles mushy by for the cost to be the same at both stores?
Answer:
The indifference point is 20 tiles.
Step-by-step explanation:
First, we need to establish the total cost formulas for each store:
Store 1:
Total cost= 10 + 0.99*x
Store 2:
Total cost= 1.49*x
x= number of tiles
Now, we equal both formulas and isolate x:
10 + 0.99x = 1.49x
10= 0.5x
10/0.5=x
20=x
The indifference point is 20 tiles.

The angles which are formed inside by the joining of arms of a triangle is called interior angles of a triangle. According to the figure provided , In ∆ ABC , ∠ABC , ∠ ACB , ∠ BAC are interior angles because they lie inside the ∆ ABC and sum of such interior angles is always 180°.

[tex] \text{{∠a \: + \: ∠ \: b \: + \: ∠ \: c \: = \: 180 \degree}}[/tex]

The value of x is 20°. As we are asked to find the measure of ∠C , substituting the value of x in 4x :
[tex] \text{∠c = 4x}[/tex]
→ [tex] \sf{∠ \: c \: = 4 \times 20 \degree}[/tex]

Hence , The measure of ∠ C is 80 °

To find:
The value of d.
Solution:
We have,
[tex]-\dfrac{1}{4}d-\dfrac{2}{5}d=39[/tex]
Taking LCM, we get
[tex]\dfrac{-5d-8d}{20}=39[/tex]
[tex]\dfrac{-13d}{20}=39[/tex]
Multiply both sides by 20.
[tex]-13d=39\times 20[/tex]
Divide both sides by -13.
[tex]d=\dfrac{39\times 20}{-13}[/tex]
[tex]d=-3\times 20[/tex]
[tex]d=-60[/tex]
Therefore, the value of d is -60.

Steve is creating a web page. He starts with a font of 5 9/10 points and decreases it by 1/2. He decreases it again by 6/10 points. Steve then realizes that the font is to small to read easily and increases it by 1 4/5 points. Which is the best estimate of the font's final size?
Answer:
6 3/5 points
Step-by-step explanation:
Steve is creating a web page.
Step 1
He starts with a font of 5 9/10 points and decreases it by 1/2.
Hence: Current font
= 5 9/10 - 1/2
= 5 + ( 9/10 - 1/2)
Lowest common denominator
= 10
= 5 + (9 - 5/10)
= 5 + 4/10
= 5 + 2/5
= 5 2/5 points
Step 2
He decreases it again by 6/10 points.
Current fonts
= 5 2/5 - 6/10
= 5 + ( 2/5 - 6/10)
Lowest common denominator
= 10
= 5 + (4 - 6/10)
= 5 + (-2/10)
= 5 - 1/5
= 4 4/5 points
Step 3
Steve then realizes that the font is to small to read easily and increases it by 1 4/5 points.
New font
= 4 4/5 points + 1 4/5 points
Lowest common denominator = 5
= 4 + 1 + (4/5 + 4/5)
= 5+ ( 4 + 4/5)
= 5 +(8/5)
= 6 3/5 points
The best estimate of the font's final size is 6 3/5 points

(a) (3/7)² (b) (7/9)³ (c) (-2/3)⁴
Solution,
(a) (3/7)²
[tex](\dfrac{3}{7})^2=\dfrac{9}{49}[/tex]
(b) (7/9)³
[tex](\dfrac{7}{9})^3=\dfrac{7\times 7\times 7}{9\times 9\times 9}\\\\=\dfrac{343}{729}[/tex]
(c) (-2/3)⁴
[tex](\dfrac{-2}{3})^4=\dfrac{-2\times -2\times -2\times -2}{3\times 3\times 3\times 3}\\\\=\dfrac{16}{81}[/tex]
Hence, this is the required solution.
A charter bus travels 225 miles in

proportional to the time spent.
Write a direct variation equation.
A) x + 50 = y
B) y + 50x = 0
C) x= - 50 y
D) y = 50x
D because y (time spent) = 50 × x (distance travelled)
225÷4.5=50

20% of 260 students at hill middle school ride a bus to school. how many students ride a bus to school?
Answer:
52 students ride a bus to school
Step-by-step explanation:
Step 1: Our output value is 260.
Step 2: We represent the unknown value with x.
Step 3: From step 1 above $260 = 100%.
Step 4: Similarly, x = 20%.
Step 5: This results in a pair of simple equations:
260 = 100%(1).
x = 20%(2).
Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both
equations have the same unit (%); we have
[tex]\frac{260}{x}[/tex] = [tex]\frac{100}{20}[/tex]%
Step 7: Again, the reciprocal of both sides gives
[tex]\frac{x}{260}[/tex] = [tex]\frac{20}{100}[/tex]
⇒x=52$
Therefore, 20% of 260 is 52.
Hope this helps! :)

The number of students who ride a bus is 52.
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
Total number of students = 260
The number of students who ride a bus.
= 20% of 260
= 1/5 x 260
= 52
Thus,
The number of students who ride a bus is 52.
