What is the measure, in degrees, of ZPTR? Enter your answer in the bo
Answer:
[tex] \purple {\bold {m\angle PTR=136\degree}} [/tex]
[tex] \orange {\bold {m\angle PQR=68\degree}}[/tex]
Step-by-step explanation:
PS and RS are tangents to the circle with center T at points P and R. (given)
TP and TR are radii of the given circle.
[tex] \therefore PS\perp TP\: \&\: RS\perp TR[/tex]
(radius is perpendicular to the tangent)
[tex] \therefore m\angle TPQ= m\angle TRS =90\degree [/tex]
In quadrilateral SPTR
[tex] m\angle TPQ+ m\angle TRS+m\angle PSR +m\angle PTR=360\degree [/tex]
[tex] 90\degree+ 90\degree+44\degree +m\angle PTR=360\degree [/tex]
[tex] 224\degree +m\angle PTR=360\degree [/tex]
[tex] m\angle PTR=360\degree - 224\degree[/tex]
[tex] \purple {\bold {m\angle PTR=136\degree}} [/tex]
By inscribed angle theorem:
[tex] m\angle PQR=\frac{1}{2} \times m\angle PTR[/tex]
[tex] m\angle PQR=\frac{1}{2} \times 136\degree[/tex]
[tex] \orange {\bold {m\angle PQR=68\degree}}[/tex]
Describe a transformation or series of transformations that demonstrates the congruence between figures A and B.
Answer:
90 clockwise (or counterclockwise) rotation and then a reflection over the axis between the two shape (those two steps go in any order)
Step-by-step explanation:
for this lets mark the innermost point of each shape a (blue or A) and a' (red or B)* and the second point b and b'
here we see that the two shapes are in a position to where they seem reflected over a non-existent third diagonal axis, though this is not the case, we need to bring the shape into a position where it can be transformed to the quadrant of shape B and overlap the shape
so when you have a reflection over a diagonal axis, we can rotate or reflect the shape to a new quadrant, and perform the step thats not the first, so say we made a reflection over the X-axis, the shape is now in the lower half of the graph with shape B, from here we perform our last step wich is to rotate the shape into the quadrant of shape B in a clockwise motion, now a and a' overlap and b and b' overlap, same for c, c',d and d'
(*the ' in this case is called a prime symbol, when used, distinguishes two points or lines on a graph, A' = A prime)

What is the slope of a line that is perpendicular to the line that passes through the points (9,0) and (3,7)?
Answer:
6/7
Step-by-step explanation:
Product of slope of perpendicular line = -1
Slope = [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\[/tex]
[tex]= \frac{7-0}{3-9}\\\\=\frac{7}{-6}\\\\=\frac{-7}{6}[/tex]
Slope of the perpendicular line = -1/m = -1 ÷ [tex]\frac{-7}{6}[/tex]
[tex]= -1 * \frac{-6}{7} = \frac{6}{7}[/tex]

Find the value of x.
A 2
B 4.8
C 6
D 6.4
Answer:
D
Step-by-step explanation:
Δ DCA and Δ ABE are similar, thus the ratios of corresponding sides are equal, that is
[tex]\frac{CA}{BE}[/tex] = [tex]\frac{DA}{AE}[/tex] , substitute values
[tex]\frac{18}{10}[/tex] = [tex]\frac{x+8}{8}[/tex] ( cross- multiply )
10(x + 8) = 144 ( divide both sides by 10 )
x + 8 = 14.4 ( subtract 8 from both sides )
x = 6.4 → D
The value of x is the length of BD, so x = 6.So, The correct answer is C. 6.
The value of x is the length of the altitude from vertex B to side AC. We can find this length by using the Pythagorean Theorem on right triangle ABD.
[tex]AB^2 + BD^2 = AD^2\\8^2 + BD^2 = 10^2\\BD^2 = 36\\BD = 6[/tex]
The altitude from vertex B to side AC is equal to the length of BD, so x = 6.
Here is a breakdown of the steps involved in solving for x:
We are given the lengths of sides AB and AC of triangle ABC.
We know that the altitude from vertex B to side AC will be perpendicular to side AC. We can use the Pythagorean Theorem on right triangle ABD to find the length of BD, which is the altitude from vertex B to side AC.

work out the size of angle A
Answer:
The measure of A is 93
Step-by-step explanation:
Here, we want to get the measure of angle A
we can start by getting the measure of angle C
Mathematically, we can use sine rule
It states that the ratio of the length of a side of a triangle and the sine of the angle it faces is constant
So to get C, we have the following;
9/sin 38 = 11/sin C
sin C = 11sin 38/9
sin C = 0.7525
C = sin^-1(0.7525)
C = 48.80
This is approximately 49
To get A,
we know that if we added the measure of interior angles of a triangle, the addition is 180 degrees
Thus, we have it that:
38 + 49 + A = 180
A = 180-38-49
A = 93
What is the area of this compound shape?
Answer:
139.36
Step-by-step explanation:
first you do 8*8 because that would be the area of the square part
8*8=64
then find the area of the semicircle
first the Radis of it is 4 because 8/2=4
A=3.14R^2/2
3.14*4^2/2
3.14*16/2
50.24/2
25.12
now because there are 3 of the semicircles you do
25.12*3
75.36
then you add the 64 from the square to get your answer
75.36+64
139.36
is -6/3 and integer? dont guess ;( helppp
Answer:
no because
Fractions and decimals are not integers. All whole numbers are integers (and all natural numbers are integers), but not all integers are whole numbers or natural numbers. For example, -5 is an integer but not a whole number or a natural number.
-6/3 is not an integer.
What is Number system?A number system is defined as a system of writing to express numbers.
We need to check whether -6/3 is a integer or not .
An integer is a whole number (not a fractional number) that can be positive, negative, or zero.
The given number is a fraction which is not comes under the integers.
All whole numbers are integers but but not all integers are whole numbers or natural numbers.
If the fraction is simplified we get -2 which will be an integer but the fraction form is not considered as integer.
Hence, -6/3 is not an integer.

A business made $1.5 million in sales this year, and estimates a 7% increase in sales for the coming year.
If the company allocates 10% of expected sales for promotional activities, how much would be allocated (set aside) for next year's promotion (advertising)?
Answer:
$160,500
Step-by-step explanation:
First, find the coming years sales
7% of 1,500,000 is 105000
105,000+1,500,00=1,605,000
1,605,000 is the next year's sales and we do that *0.1 to find the advertising.
1,605,000*0.1=160,500
So 160,500 will be set aside for advertising

Find the measure of the given angles. Show work!!
Answer:
m∠A = 45⁰
m∠B = 75⁰
Step-by-step explanation:
Given question 4;
m∠A = x + 51
m∠B = 81 + x
m∠C = 60⁰
The value of the missing angles can be determined by the finding the value of x first;
m∠A + m∠B + m∠C = 180⁰ (sum of angles in a triangle)
(x + 51) + (81 + x) + 60⁰ = 180
(x + x) + (51 + 81 + 60) = 180
2x + 192 = 180
2x = 180 - 192
2x = -12
x = -12/2
x = -6
Thus, the values of the angles are calculated as follows;
m∠A = x + 51
= -6 + 51
= 45⁰
m∠B = 81 + x
= 81 - 6
= 75⁰
A fountain holds 12500 7/8 gallons of water. Joe wants to calculate how many liters that is. Which proportion could he use to solve for the number of liters? (1 gal = 3.79 L)

Step-by-step explanation:
A fountain holds 12500 7/8 gallons of water. Joe wants to calculate how many liters that is. Which proportion could he use to solve for the number of liters? (1 gal = 3.79 L)
From the above question,
1 gallon = 3.79 Liters
12500 7/8 gallons = x Liters
Cross Multiply
x Liters = 12500 7/8 × 3.79 Liters
x = 47378.31625 Liters
Therefore, the number of liters of water in the fountain is 47378.31625 Liters
