. If QS bisects angle PQR, m angle PQS = (7x - 6)° , and m angle SQR = (4x + 15)° , find m angle PQT.
Answer:
94
Step-by-step explanation:
PQS = (7x - 6)°
SQR = (4x + 15)° since QS bisect PQR these two expressions must be equal
so
7x - 6 = 4x + 15 transfer like terms to the same side of the equation
7x - 4x = 15 + 6
3x = 21 divide both sides by 3
x = 7
also the sum of these two would give us the measure of PQR
7x + 4x + 15 - 6 = PQR
11x + 9 = PQR replace x with 7
11*7 + 9 = 86 this is the measure of angle PQR and also supplementary to PQT so the measure of PQT = 180 - 86
If QS bisects angle PQR. the m<PQT=94 °
Given :
Measure of angles PQS = (7x - 6)° , and m angle SQR = (4x + 15)°
QS bisects angle PQR. So m<PQS=m<SQR

Now we find out m<PQR
[tex]m<PQR=m<PQS+m<SQR\\m<PQR=7x-6+4x+14\\m<PQR=11x+8\\x=7\\m<PQR=11(7)+8=85[/tex]
We know that <PQR and <PQT are linear pair of angles
The sum of linear pair of angles are supplementary
[tex]m<PQR+m<PQT=180\\86+m<PQT=180\\m<PQT=180-86\\m<PQT=94[/tex]

x=19.27329
A worker with a wheelbarrow filled with bricks starts at a point 50 m from the
entrance to a construction site. The worker pushes the wheelbarrow away from the
entrance at a speed of 1 m/s for 10 s, stops for 5 s to unload, and then moves back
toward the entrance at a speed of 2 m/s for 20 s. Draw a distance-time graph.
Step-by-step explanation:
Given
Worker started from a point 50 from entrance. The worker pushes it away from the entrance at a speed of 1 m/s for 10 s that is there is no acceleration for 10 s as speed is constant.
Distance covered in this time is given by
[tex]\Rightarrow s_1=1\times 10\\\Rightarrow s_1=10\ m[/tex]
It is stopped for 5 s and then starts moving towards entrance with a speed of 2 m/s for 20 s. Also, there is no acceleration.
distance traveled in this time
[tex]\Rightarrow s_2=2\times 20\\\Rightarrow s_2=40\ m[/tex]
As, distance cannot shown negative. It is shown in increasing manner.

AABC is a right triangle in which zB is a right angle, AB = 1, AC = 2. and BC = V3.
COS Cx sin A =
The value of COS Cx sin A by the given data is V3/4.
What are trigonometric identities?Trigonometric identities are the functions that include trigonometric functions such as sine, cosine, tangents, secant, and, cot.
Trigonometric ratio can be defined in terms of ratios of perpendicular, bases and hypotenuse. These are defined only in right angled triangles (triangles whose one angle is of 90 degree measure).
We are given that;
AB = 1, AC = 2 and BC = V3
Now,
To find the value of cos C x sin A, we need to use the trigonometric ratios of the right triangle.
We know that cos C = adjacent/hypotenuse = AB/AC = 1/2 and sin A = opposite/hypotenuse = BC/AC = V3/2.
cos C x sin A = (1/2) x (V3/2) = V3/4.
Therefore, by the trigonometric ratio the answer will be V3/4.

357 students went on a field trip. Eight
buses were filled and 5 students traveled
in cars. How many students were in each
bus?
Answer:
There were 44 students in each bus.
Step-by-step explanation:
357 - 5 = 352
352/8 = 44
Answer:
Step-by-step explanation:
Total students = 357
Total buses filled = 8
No of students traveled in car = 5
Remaining students = 357 - 5 = 352
Students in each bus = 352 ÷ 8 = 44 students
The value of a jewel in 2015 was $17500. The jewel was purchased in 2008, and its value appreciated 2.5%
each year. What was the initial value of the jewel when it was first bought? Round to two decimal places
Answer:
$14722.14
Step-by-step explanation:
We are given that
In 2015
The value of jewel=$17500
Rate of appreciation, r=2.5%
We have to find the initial value of the jewel when it was first bought.
Time, n=7 years
Final value=[tex]Initial\;value (r/100+1)^n[/tex]
Using the formula
[tex]17500=Initial\;value(2.5/100+1)^7[/tex]
[tex]17500=Initial\;value(1.025)^7[/tex]
[tex]Initial\;value=\frac{17500}{(1.025)^7}[/tex]
Initial value=$14722.14
Hence, the the initial value of the jewel when it was first bought=$14722.14

How many solutions can be found for the equation 3y + 5 − 2y = 11?
A. Zero
B. One
C. Two
D. Infinitely many
Answer:
B one
Step-by-step explanation:
3y + 5 - 2y = 11
3y -2y + 5 = 11
Combine like terms
y + 5 = 11
Subtract 5 from both sides
y = 11 - 5
y = 6
So, Only one solution
Answer:
there is only 1 solution.
Step-by-step explanation:
We can solve the equation to find it's number of solutions, but we already know it only has 1 solution because it is a linear equation (y is raised to the first power).
3y + 5 − 2y = 11
y + 5 = 11
y = 6
This confirms that there is only 1 solution.-------

If 7x^2 - mx-12 is equal to (7x + n)(x-6), where m and n are constants, find the value of m.
Answer:
m=40
Problem:
If 7x^2 - mx-12 is equal to (7x + n)(x-6), where m and n are constants, find the value of m.
Step-by-step explanation:
We want to find n amd m such that
(7x+n)(x-6)=7x^2-mx-12.
Since (ax+b)(cx+d)=acx^2+(ad+bc)x+bd, then we need or should have the following:
(7x)(x)=7x^2
(7×-6+n×1)x=-mx
(n)(-6)=-12
The bottom equation tells us n=2 since 2(-6)=-12.
The first equation is already true.
Now we must solve (7×-6+n×1)x=-mx with n=2 for m.
That is we need to solve 7×-6+2×1=-m
Simplify and done -m=-42+2=-40 so m=40.
Let's do a check
7x^2 - mx-12 is equal to (7x + n)(x-6)
7x^2-40x-12 is equal to (7x+2)(x-6)
(7x+2)(x-6)=7x(x)+7x(-6)+2(x)+2(-6)
(7x+2)(x-6)=7x^2-42x+2x-12
(7x+2)(x-6)=7x^2-40x-12 and that is what we wanted.
Another way:
We want (7x+n)(x-6)=7x^2-mx-12 to be true for all x.
So if x=0 or for x=1, we want the equation to be true.
Insert x=0. This gives (n)(-6)=-12 which implies n=2.
(7x+2)(x-6)=7x^2-mx-12
Insert x=1. This gives (7+2)(1-6)=7-m-12.
Simplify both sides: 9(-5)=-m-5
Continue to simplify left side: -45=-m-5
Add 5 on both sides: -40=-m
Multiply both sides by -1: 40=m

In a taste test, five different customers are each presented with 3 different soft drinks. The same soft drinks are used with each customer, but presented in random order. If the selections were made by random guesses, find the probability that all five customers witnesses would pick the same soft drink as their favorite. (There is more than one way the customers can agree.)
Answer:
0.01235
Step-by-step explanation:
we can solve for probability by using the formula;
favourable outcome/total number of outcomes
in this question, the number of favorable outcome = 3
the total number of outcomes = 3⁵
= 3x3x3x3x3 = 243
probability = 3/243
= 0.012345678
this can be approximated to be 0.01235
0.01235 is therefore the probability that all 5 customers would pick the same soft drink as their favorite drink.
