Answer:

Step-by-step explanation:
The hardest part about negative numbers in addition is remembering when to add, rather than subtract. In the last equation, we add the numbers together, because the negative sign cancels out with subtraction. All of the other equations we can follow exactly what it says to do, because there are no minus signs right next to each other.

Answer:
∠SPR = 48°
Step-by-step explanation:
The relevant relations are ...
an inscribed angle is half the measure of the arc it interceptsa triangle inscribed in a semicircle is a right trianglean exterior angle is equal to the sum of the remote interior angles of a triangleSince PR is a diameter, triangle PQR is a right triangle with angle PQR being the right angle.
This makes ∠PRQ complementary to ∠RPQ:
∠PRQ = 90° -28° = 62°
Exterior angle RTS is the sum of interior angles TRQ and TQR, so angle TQR can be found to be ...
110° = 62° +∠TQR
∠TQR = 110° -62° = 48° = ∠SQR
__
Angle TQR, also angle SQR, subtends arc SR, so is the same measure as angle SPR, which also subtends the same arc.
∠SPR = 48°
how to find x in 64°,50° and 2x
Answer:
x = 33 degree
Step-by-step explanation:
angles of a triangle = 64 degree , 50 degree , 2x
64 + 50 + 2x = 180 degree (sum of interior angles of a triangle)
114 + 2x = 180
2x = 180 - 114
x = 66/2
x = 33 degree
to find 2x
=2*33
=66 degree

Show the relationship between the number of weeks and Mike's savings using an equation. Type your answer starting with either "W=" or "S=".
Answer:
S = 50w + 75
Step-by-step explanation:
After each week, Mike gains $50.
Letting w = 0 gives us the amount he started with. In this case, that would be $75.
Therefore, the equation is S = 50w + 75.

To find:
The property that Rahal use to rewrite the expression.
Solution:
According to the associative property of addition, if a, b and c are three real numbers, then
[tex]a+(b+c)=(a+b)+c[/tex]
We have,
[tex]-3+[(-7)+(-6)][/tex]
Using the associative property of addition, we get
[tex]-3+[(-7)+(-6)]=[(-3)+(-7)]+(-6)[/tex]
Therefore, the required property is associative property of addition.
Given that √5=2.24 and √7.07, find the value of
(a) √0.05
(b)√0.0005
(c)√0.5
(d)√0.005
Answer:
0.05 = 5/100
sqrt(0.05] = sqrt(5/100) = sqrt(5)/sqrt(100) = 2.24/10 = 0.224
0.0005 = 5/10000
sqrt [0.0005) = sqrt(5/10000) = sqrt(5)/sqrt(10000) =
= 2.24/100 = 0.0224
0.5 = 50/100
sqrt(0.5) = sqrt(50/100) = sqrt(50)/sqrt(100) = 7.07/10 =
= 0.707
0.005 = 50/10000
sqrt(0.005) = sqrt(50/10000) = sqrt(50)/sqrt(10000) =
= 7.07/100 = 0.0707

Maya is flying a kite, holding her hands a distance of 3.5 feet above the ground and letting all the kite’s string play out. She measures the angle of elevation from her hand to the kite to be 34^{\circ}
∘
. If the string from the kite to her hand is 125 feet long, how many feet is the kite above the ground? Round your answer to the nearest tenth of a foot if necessary.
Answer:
The kite is 73.4 feet above the ground.
Step-by-step explanation:
125 sin 34=
Cross multiply.
x=69.899112...
x=69.899112...
{Add 3.5, the distance from the ground to her hand:}
Add 3.5, the distance from the ground to her hand:
69.899112...+3.5=
73.399112...
The kite is 73.4 feet above the ground.
A right angled triangle is a triangle (has three sides and three angles) in which one of the angles measure 90°.
Trigonometric ratios is used to show the relationship between the sides of the right angled triangle and its angles.
Let h represent the perpendicular distance from the top of the kite to her hand. The angle of elevation = 34°. Hence:
sin(34) = h/125
h = 69.9 feet
The distance from the kite to the ground = 69.9 + 3.5 = 73.4 feet

1+2+4-5= -5+4+2+1
A) True
B False
Answer:
True
Step-by-step explanation:
same numbers on both sides = equivalent expression
1+2+4 = 7
7-5 = 2
So the first side is 2
-5 + 4 = -1
-1 + 2 + 1 = 2
So the second side is 2
Simplified, this is 2 = 2
This is TRUE because this is an equivalent expression, demonstrated by the equal sign.

Are the only bases that I need to use 2 and 4 along with the height 2.5 and I just ignore the 3?
Answer:
[tex]7.5\ units^2[/tex]
Step-by-step explanation:
The formula to find the area of a trapezoid is the following,
[tex]A=(h)(\frac{(b_1)+(b_2)}{2})[/tex]
Where ([tex]h[/tex]) represents the heights of the trapezoid, ([tex]b_1[/tex]) and ([tex]b_2[/tex]) represent the bases of the trapezoid, or rather the two parallel sides of the trapezoid.
One is given all of these values in the picture,
[tex]h = 2.5\\\\b_1 = 2\\\\b_2 = 4[/tex]
Substitute these values into the formula and solve for the area of the trapezoid,
[tex]A=(2.5)(\frac{(2)+(4)}{2})[/tex]
Simplify,
[tex]=(2.5)(\frac{6}{2})\\=(2.5)(3)\\=7.5[/tex]
a bag contains 517.6 g of dollar coins. Each coin has a mass of 8.1 g
Answer:
63 coins
Step-by-step explanation:
I am going to assume you are asking how many dollar coins are in the bag, I apologize if I am wrong.
So first, set up the problem. The total number is 517.6 and each coin weighs 8.1
So you would divide 517.6 by 8.1 to get 63.9012346 (which has too many decimal points so round)
But rounding up would get the wrong number because it would be too light for the amount of coins said to be in there, but rounding down gives you 63.
So 63 times 8.1 is 510.3 and the total could consider the weight of the bag into the total 517.6.

Jenna is a 6th grader at CMS. Jenna was told her mean score on social studies quizzes was 94. She remembered getting scores of 97, 88, 90, and 95, but she knew she had taken 5 quizzes. What was her fifth quiz score?
Answer: 100
Step-by-step explanation:
Since she had a mean score of 94 in her 5 tests, then the total score will be:
= 94 × 5
= 470
Since she She remembered getting scores of 97, 88, 90, and 95, for 4 quizzes out of 5 quizzes, the total of the four quizzes will be:
= 97 + 88 + 90 + 95
= 370
Then, her 5th quiz will be:
= 470 - 370
= 100
