i need help finding the area of these two
Answer:
50 cm² and 56 cm²
Step-by-step explanation:
The area (A) is calculated as
A = [tex]\frac{1}{2}[/tex] × d₁ × d₂ ( d₁ and d₂ are the length of the diagonals )
(2)
A = [tex]\frac{1}{2}[/tex] × (8 + 2) × (5 + 5)
= 0.5 × 10 × 10
= 5 × 10
= 50 cm²
(3)
A = [tex]\frac{1}{2}[/tex] × (12 + 2) × (4 + 4)
= 0.5 × 14 × 8
= 7 × 8
= 56 cm²

Answer:
35 degrees
Step-by-step explanation:
since the total has to be 180
100 + 45 = 145
180 - 145 = 35 degrees
Answer:
35 degrees
Step-by-step explanation:
A triangle is 180 degrees and 45 and 100 is already there.
So... 180-45-100=35
That is how you get 35 degrees

if 36/5x=3/5 what is x
Answer:
x = 12
Step-by-step explanation:
Given
[tex]\frac{36}{5x}[/tex] = [tex]\frac{3}{5}[/tex] ( cross- multiply )
15x = 180 ( divide both sides by 15 )
x = 12

Answer:h
Step-by-step explanation:
Convert: a) 8250 g =________________kg b) 10 3/4 l =______________ ml c) 6 m 5 cm =_____________ cm d) 9 km 50 m =____________m *
Answer:
See answers below
Step-by-step explanation:
Convert: a) 8250 g =________________kg b) 10 3/4 l =______________ ml c) 6 m 5 cm =_____________ cm d) 9 km 50 m =____________m *
a) Note that 1000g = 1kg
8250g = x
1000 * x = 8250
1000x = 8250
x = 8250/1000
x = 8.25kg
b) 10 3/4 l to ml
1l = 0.001ml
10 3/4 l = x
Cross multiply
1 * x = 10 3/4 * 0.001
x = 43/4 * 0.001
x = 0.043/4
x = 0.01075ml
c) 6m 5cm to cm
Since 1m = 100cm
6m 5cm
= 6(100) + 5
= 600 + 5
= 605cm
d) 600km 50m to m
1000m = 1km
x = 9km
x = 9000m
600kn 50m
= 9000m + 50m
= 9050m

kali runs 12 laps around a track each day. Each lap around the track is 400 meters. How many days will it take Kali to run the total of 12 kilometers?
Answer: 2.5 days
Step-by-step explanation:
First we should convert 12 kilometers to meters so that is 12000 meter. Now we know that she runs 12 laps each day and each lap is 400 meters so lets find out how much she runs in one day. 12 laps*400meters= 4800 meters
So an easy way to figure out how many days is to divide 4800 meters she runs each day from the total 12,000 meters she needs to run so 12,000/400=2.5.
It will take kali a total of 2.5 ( two and a half days) to run 12000 meters or 12 kilometers

Find the measure of the indicated angle to the nearest degree
Answer:
32°
Step-by-step explanation:
use this formula :
Now you want to get the angle be x, so the opposite side is 28 and hypotenuse is 53. Putting in the formula we get:
Sin(x) = 28/53
Sin(x)= 0.5283018868
So to find x just do Sin^-1
x = Sin^-1 (0.5283018868)
you get 31.8907918, ok so we just want the nearest degree and if we do that we get 32˚
if you put them into your calculator you will get 32˚ as your answer

You are planning a trip to Yellowstone National Park, and know that you can save money by driving
and staying with family along the way. The first leg of your journey will be 426 miles from Portland,
OR to Boise, ID where your aunt lives. After visiting with her, you will drive 388 more miles to
Yellowstone. Estimate the number of miles you will drive to get to Yellowstone National Park by
first rounding to the tens place.
Answer:
the number of miles that you would drive to go the yellowstone is 814 miles
Step-by-step explanation:
The computation of the number of miles that you would drive to go the yellowstone is shown below:
= First leg of the journey from portland + more drives to yellow stone
= 426 miles + 388 miles
= 814 miles
Hence, the number of miles that you would drive to go the yellowstone is 814 miles

Calculate the area of a circle with a diameter of 8cm.
Show all your work.
A≈50.27cm²
Using the formulas
A=πr2
d=2r
Solving forA
A=1
4πd2=1
4·π·82≈50.26548cm²
Answer:
16π cm^2
Step-by-step explanation:
The formula for the area of a circle is [tex]\pi r^{2}[/tex], r being the radius. The radius is always half of the diameter, so in this case, the radius is 4. [tex]4^{2}[/tex] is just 4 * 4 which is 16. Multiply that by π and you get 16π. Or, approximately 50.27 cm^2
Find the measure of the arc.
A
146°
E
B
MABC = [ ? 1°
Answer:
i get mABC = 270°
Step-by-step explanation:
This is fairly straight forward once you the right angle symbol for the arc AC. Also realizing the 148° for mAB is not needed for this question. The 148° for mAB would be useful if you wanted to calculate arc mBC.
Remember there are 360° in a circle.
The arc mAC is 90°
The arc mABC is the rest of the circle. is the arc from A to B to C
arc ABC + arc AC is the full circle 360°
mABC + mAC = 360° mAC = 90°
mABC + 90° = 360° - 90° from both sides
mABC = 360° - 90°
mABC = 270°
The angle ∠ABC in the given circle will be 270°.
What is an angle?
An angle is a geometry in plane geometry that is created by 2 rays or lines that have an identical terminus.
Angle is very useful to measure any angular rotational motion for example if you have to find out the rotation among the circle then it cannot measure in length parameter such that meter inch so it will be measured as an angle in a unit of degree or radian.
In another word, the angle is the measurement of the angular distance for example for linear motion we have a meter inch but for angular rotation, we don't have the measurement so the angle is useful to measure the angular rotation.
Now since we know that the angle of complete rotation is 360°.
Now ∠ADC + ∠ABC = 360
Given that ∠ADC = 90°
∠ABC = 360° - 90° = 270°
Hence, 270° will be the correct answer.

The height in meters of a toy rocket at t seconds can be found by the
function h(t) = -5t2 + 40t + 1.2 Find the height of the toy rocket 4 seconds
after it is launched.
Answer: 81.2
Step-by-step explanation:
h(t) = -5t² + 40t + 1.2
h(4) = -5(4)² + 40(4) + 1.2 We plug 4 seconds as t, and solve h(4)
h(4) = -80 + 160 + 1.2
h(4) = 80 + 1.2
h(4) = 81.2

Half of R is shown as 20 degrees, so the other half of r is also 20 degrees.
A tangent line forms a right angle, so the tangent at P is 90 degrees.
X would be 180 - 90 - 20 = 70 degrees.
X = 70 degrees.

Answer:
5) ∅ =3.94°
6) ∅ = 22.19°
Step-by-step explanation:
5) tan ∅ = 3.9/56.67
tan ∅ = 0.0688
∅ =3.94°
6) cos ∅ = 250/270 (500/2 = 250)
cos ∅ = 0.9259
∅ = 22.19°
A rectangle has vertices located at (–4, 4), (2, 4), (2, –4) and (–4, –4). What is the length of a diagonal of the rectangle?
Answer:
A diagonal of this rectangle has length 10.
Step-by-step explanation:
The vertices (-4, 4) and (-4, -4) have the same x-coordinate (-4) and different y-coordinates (4 and -4). These two points are the endpoints of a vertical side of the rectangle which has length 4 - (-4) = 8.
Similarly, the vertices (2, -4) and (-4, -4) have the same y-coordinate (-4) but different x-coordinates (2 and -4). To find the horizontal dimension of the rectangle, we calculate 2 - (-4), which comes out to 6.
Thus, the width of the rectangle is 6 and the length is 8.
Using the Pythagorean Theorem, we find the length of a diagonal as follows:
d = √(6^2 + 8^2) = √(36 + 64) = √100 = 10.
A diagonal of this rectangle has length 10.
