Answer:
m<QRS=48°
m<RSQ=69°
m<RQS=63°
Step-by-step explanation:
Since we know that the measures of the angles of any triangle is 180°, we can form this equation: 7a-1+10a-1+9a=180°
Then, we can use simple algebra to solve for a and plug in that value into the equations that the degrees represent to get our angle measures.
7a-1+10a-1+9a=180°
26a-2=180°
26a=182°
a=7
Now, plug in that value of a and you have your anlage measures!! Hope this helps!! :)

if the product (2x + 3)(x + k) is 2x^2 + 13x + 15, what is the value of k?
Answers
Answer: k = 5
(2x + 3)(x + k)
= 2x.x +2x.k + 3x + 3k
= 2x² + x(2k + 3) + 3k
because (2x + 3)(x + k) is 2x^2 + 13x + 15
=> 3k = 15
2k + 3 = 10
=> k = 5

distance from Houston to Galveston in
kilometers?
Answers
Answer:
distance from Houston to Galveston in kilometers will be: 80km
Step-by-step explanation:
Given
The distance from Houston to Galveston is about 50 miles.
i.e.
Kilometers in 1 Mile = 1.6 km
As the distance from Houston to Galveston is about 50 miles, so
The distance from Houston to Galveston in kilometers will be:
50(1.6) = 80 ∵ Kilometers in 1 Mile = 1.6 km
Therefore,
The distance from Houston to Galveston in kilometers will be: 80km

Find the measure of angles 3 and 4
Answers
Answer: 3 =92
4 = 88
Step-by-step explanation: because angle 4 = 180-42+46 = 92 and angle 3 is 180-92 = 88
Answer:
∠3=88 , ∠4=92
Step-by-step explanation:
∠4 + 42° + 46° = 180° (angle sum property of a triangle)
∠4 + 88° = 180°
∠4 = 180° - 88°
∠4 = 92
∠3 + ∠4 = 180° (linear pair)
∠3 + 92° = 180°
∠3 = 180° - 92°
∠3 = 88°
the soloutions to the equation 2x^2 + x - 1 = 2 are x= -3/2 or x=___

Answer:

Step-by-step explanation:
Subtracting 2 puts the equation in standard form:
2x^2 +x -3 = 0
The product of the solutions is the ratio of the constant term to the leading coefficient: -3/2.
For solutions -3/2 and 'p', we have ...
-3/2p = -3/2
p = 1
The other solution is x = 1.

Answers
Answer:
0.1787
Step-by-step explanation:
It is given that the mean cost of undergraduate program for a four year institutions for tuition, rooms fees and board was =$26,489
And the minimum standard deviation is given as σ = $ 3204
So, the mean normal deviation is , μ = 26,489
and the standard deviation is, σ = 3204
Thus, the probability of the mean cost for sample schools is 0.1787

(A) 3/16 of a day 0.25 of a day (B) 0.25 of a day 1/3 of a day (C) Amber spends time doing homework than she does at school. (D) Amber spends time sleeping than she does at school.
Answers
Answer: (D) Amber spends time sleeping than she does at school.
Step-by-step explanation:
Given that :
• Amber spends 3/16 of each day doing homework.
• Amber spends 0.25 of each day at school.
• Amber spends 1/3 of each day sleeping.
Hence,
Amber spends 0.1875 of a day doing homework, which is (0.1875 * 24) = 4.5 hours
0.25 of each day at school ; (0.25 * 24) = 6 hours
1/3 of each day sleeping ; (1/3 * 24) = 8 hours
Time spent sleeping = 8 hours
Time spent in school = 6 hours

The area of a rectangular park is same as area of a square park. If the length
of the rectangular park is 24.5 m and the side length of the square park is 14m,
find the breadth of the rectangular park?
Answers
Answer:
8mStep-by-step explanation:
Step one:
given data
length of rectangle= 24.5m
let the width be x
width of square= 14m
let the length be x
Step two:
we know that the area of a rectangle is
Ar= Length * width
Ar=24.5*x-----------1
Also, the area of the square is
As= Length * width
for square L=W
As= 14*14-----------------2
As=196m^2
equating 1 and 2 we have
14*14=24.5x
196=24.5x
divide both sides by 24.5
x=196/24.5
x=8m
The Breadth/width of the rectangular park is 8m

A rectangle has a length of 31 inches less than 3 times its width. If the area of the rectangle is 984 square inches, find the length of the rectangle.
Answers
Answer:
41 inches
Step-by-step explanation:
The formula for Area of a rectangle is ;
A = L × W
L = Length
W = Width
A rectangle has a length of 31 inches less than 3 times its width.
L = 3W - 31
If the area of the rectangle is 984 square inches, find the length of the rectangle
Hence,
984 = (3W - 31) × W
984 = 3W² - 31W
Hence
3W² - 31W - 984
3W(W - 24) + 4(W - 24) = 0
(3W + 41)(W - 24) = 0
W - 24 = 0
W = 24 inches
We have to find the Length
L = 3W - 31
L = 3(24) - 31
L = 72 - 31
L = 41 inches
The Length = 41 inches
The Length of the rectangle is 41 inches
