What is the sum of 5.3 x 10 5 and 3.8 x 104 in scientific notation?
5.3×10^5=53×10^4
53×10^4+3.8×10^4
=56.8×10^4
=5.68×10^5. Hope it help!
Answer:
5.68 x 10^5
Step-by-step explanation:
5.3 x 10^5 + 3.8 x 10^4 = 5.68 x 10^5
the sum of 2 numbers is 18 while the product is -63. find the numbers.
Answer:
Step-by-step explanation:
let the numbers be x and y,then
x+y=18
x=18-y
also xy=-63
(18-y)y=-63
18y-y²=-63
y²-18y-63=0
y²-21y+3y-63=0
y(y-21)+3(y-21)=0
(y-21)(y+3)=0
y=21,-3
when y=21
x=18-21=-3
when y=-3
x=18-(-3)=18+3=21
so numbers are -3 and 21.
help solve for angle A
[tex]\huge{ \mathfrak{ \underline{ \underline{Answer }}\: \: ✓ }}[/tex]
The given Angles are Alternate Exterior Angle pair, so their measures will be equal :
[tex]6x - 2 = 4x + 48[/tex][tex]6x - 4x = 48 + 2[/tex][tex]2x = 50[/tex][tex]x = 25[/tex]Now,

b = 61.66
D
b = 24.05
9514 1404 393
Answer:
B. 7.85
Step-by-step explanation:
Your knowledge of the triangle inequality tells you 'b' cannot be greater than 11+14 = 25, eliminating choices A and C. If 'b' were 24.05, as suggested by choice D, the angle at B would be nearly a straight angle.
So, the only viable choice is b = 7.85.
__
Your knowledge of "special" triangles tells you that if B were 30°, then b would be 14/2 = 7.0. The angle is slightly larger than that, so the side opposite is slightly larger than 7.0.
__
In this geometry, the Law of Cosines would be used to find b. That relationship tells you ...
b = √(a^2 +c^2 -2ac·cos(B))
b = √(121 +196 -308·cos(34°)) ≈ √61.66 ≈ 7.85

About special triangles
There are two "special" right triangles whose trig functions are not difficult to remember. They appear quite often in algebra, geometry, and trig problems, so remembering their properties can be useful.
A 30°-60°-90° right triangle has side lengths in the ratios 1 : √3 : 2. The shortest side is exactly half the length of the hypotenuse. This fact is what we referred to above.
A 45°-45°-90° isosceles right triangle has side lengths in the ratios 1 : 1 : √2. This is the triangle you get by drawing a diagonal in a square. These ratios tell you the diagonal of a square is always √2 times the side length.
Juliet coaches softball and soccer. she coaches both sports for 15 hours each day. soccer practice is 1.5 more hours more than 3 times as long as the softball practice. write a system of equations to model the situation.
Answer: See explanation
Step-by-step explanation:
Let the number of hours used for softball practice be x.
Since soccer practice is 1.5 more hours more than 3 times as long as the softball practice. This will be:
= (3 × x) + 1.5 = 3x + 1.5
Therefore, we add both and equate to 15.
x + 3x + 1.5 = 15
4x + 1.5 = 15
4x = 15 - 1.5
4x = 13.5
x = 13.5/4
x = 3.375
Softball is practiced for 3.375 hours

please help me before the bots do thank you!!!
Answer:
517.5 mi^2
Step-by-step explanation:
Divide shapes into 3 shapes ( 1 triangle and 2 rectangles
b = 17
h = 25
Area of triangle = [tex]\frac{1}{2}[/tex] Bh
A = [tex]\frac{1}{2}[/tex] (17)(25)
A = 212.5 mi^2
Area of 1st rectangle = lw = 17(9) = 153 mi^2
Area of 2nd rectangle = lw = 19(8) = 152 mi^2
Area of figure = 212.5 +153 + 152 = 517.5 mi^2

Can 9.48 be the probability of an outcome in a sample space?
9514 1404 393
Answer:
No
Step-by-step explanation:
A probability is a unitless value between 0 and 1, inclusive. 9.48 cannot be a probability (too big). 0.4 acres cannot be a probability (has units).
There are 3 apples, 4 oranges and 1 pear in a bag. Find each probability
1) Select an orange and then a pear(without replacement)
2)You select an orange then an apple then a pear without replacement
3)You select an Apple, then an orange, then another apple without replacement
Help please
Answer:
8 fruit total
1) orange probability: 4/8 = 1/2
pear probability after one fruit is taken out: 1/7
probability of getting one then the other without replacement: 1/2 x 1/7 = 1/14
2) orange: 1/2
apple: 3/7
pear: 1/6
probability of getting them in order without replacement: 1/2 x 3/7 x 1/6 = 1/28
3) apple: 3/8
orange: 4/7
apple: 2/6 = 1/3
probability of getting them in order without replacement: 3/8 x 4/7 x 1/3 = 1/14
Answer:2/6 or 33% chance of getting an apple, 3/24 or 13% of getting a pear and 13/24 or 54% chance of getting an orange hope that helps.
