Answer:
55,000 milligrams
Step-by-step explanation:
........
Answer:
55,000 milligrams (mg) is equal to 55 grams (g)
Step-by-step explanation:
(55 g/1 )* (1000 mg/1 g)
Multiply the top to get 55,000 and the bottom to get 1.
55,000/1
The gram units cancel out, leaving you with milligrams.
55,000 mg

solve for x
Answer:
X = 60°
Step-by-step explanation:
the angle you are looking for is a corresponding angle to the angle given (121°)
2x + 1 = 121
121 - 1 = 2x
121 - 1 = 120
2x = 120
120/2 = 60
X = 60
x + y = 3
x^2 + y^2 = 5
Solve
Answer:
(1, 2 ), (2, 1 )
Step-by-step explanation:
Given the 2 equations
x + y = 3 → (1)
x² + y² = 5 → (2)
Rearrange (1) expressing y in terms of x by subtracting x from both sides
y = 3 - x → (3)
Substitute y = 3 - x into (2)
x² + (3 - x)² = 5 ← expand and simplify left side
x² + 9 - 6x + x² = 5
2x² - 6x + 9 = 5 ( subtract 5 from both sides )
2x² - 6x + 4 ( divide through by 2 )
x² - 3x + 2 = 0 ← in standard form
(x - 1)(x - 2) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 1 = 0 ⇒ x = 1
x - 2 = 0 ⇒ x = 2
Substitute these values into (3) for corresponding values of y
x = 1 : y = 3 - 1 = 2 ⇒ (1, 2 )
x = 2 : y = 3 - 2 = 1 ⇒ (2, 1 )
Kellie is purchasing the package of dog food shown (dog kibble 7pounds) how many 8 ounce servings can she feed her dog
Answer:
14 servings
Step-by-step explanation:
Step 1
We convert 7 pounds to ounces
0.0625 pound = 1 ounce
7 pounds = x
Cross Multiply
0.0625x = 7
x = 7/0.0625
x = 112 ounces
Step 2
The number of 8 ounce servings she can give to her dog is calculated as:
8 ounces = 1 serving
112 ounces = x servings
Cross Multiply
8 × x = 112 × 1
8x = 112
x = 112/8
x = 14 servings
Therefore, the number of 8 ounce servings she can feed her dog is 14

3. Find the surface area for the given cylinder. Use 3.14 for r and round to the nearest whole number. (1 point)
A. 904
B.1,017
C.1,130
D.2,713
Answer:
C
Step-by-step explanation:
The surface area of a cylinder is given by the formula:
[tex]SA=2\pi rh+2\pi r^2[/tex]
Where h is the height and r is the radius of the cylinder.
The given radius is 6 and the height is 24.
We are also using 3.14 for π.
Therefore;
[tex]SA\approx 2(3.14)(6)(24)+2(3.14)(6)^2[/tex]
Evaluate:
[tex]SA\approx1130.4\approx 1130[/tex]
The answer is C.

Forty students went on a trip on Wednesday. On Thursday, 15% less students went on a similar trip. How many students went on the trip on Thursday?
Answer:
34
Step-by-step explanation:
40 * .15= 6
40-6 = 34
okkk so you do 40 * .15 because you just put a decimal point before all percentages to convert it into number
40*.15= 6
then subtract 6 to the original amount
40-6=34
34 students went on the trip on thursday cause 6 students got killed by bears in the last trip.

If A= {x:xis a factor of 72}
B= {x:%2x+3<2x-3).
C= {x:x<20} and A,B,Ccu.
Where u = {integers), list the
elements of AnBnc.
that small c is subset and the small n is intersection set
Answer:
{2, 3, 4, 6, 8, 9, 12, 18}
Step-by-step explanation:
If A= {x: xis a factor of 72}
A = {2, 3, 4, 6, 8, 9, 12, 18, 36, 72}
If B= {x: 2x+3<2x-3).
-2x+3 <2x-3
-2x - 2x < -3-3
-4x < -6
x > 3/2
If
C= {x:x<20}
C = {-∞, 19}
The intersection of the sets AnBnc = {2, 3, 4, 6, 8, 9, 12, 18}
Note that intersection means all the elements common to the three sets
Given: E is the midpoint of overline BD and overline AC perp overline BD .
Prove : triangle BAE cong triangle DAE .
Answer:
u can prove using SAS congruency
Step-by-step explanation:
Ae=Ae common
BE=DE (E MID POINT)
Angle E=angle E (90 degree)
The ΔBAE is congruent to ΔDAE.
Given to us,
E is the midpoint of ,
AC⊥ BD,
As given E is the midpoint of the line [tex]\overline{BD}[/tex],
So, BE = ED,
further, line AE = AE, because this is the common line between the two triangles.
Also, ∠BED =∠DEA =90°, as AC⊥ BD.
Therefore, the ΔBAE is congruent to ΔDAE.

On a blueprint, the diagram of a building has a height of 25 cm.
The height of the building is x times the height of the diagram.
Which equation represents the height, h, of the building?
h = 25 : x
B
x = 25h
h = 25 + x
h = 25x
Answer:
h = 25x
Step-by-step explanation:
Given the following
height of building = h
height of diagram = 25cm
If the height of the building is x times the height of the diagram, then;
h = x * 25
h = 25x
Hence the required equation is h = 25x

A rock is thrown down from a cliff that is 180 m high. The function
h(t) = -5t^2 – 10t + 180 gives the approximate height of the rock
above the water, where h(t) is the height in metres and t is the time
in seconds. When will the rock reach a ledge that is 105 m above
the water?
Answer:
t = 3
Step-by-step explanation:
105 = -5t^2 -10t + 180
-75 = -5t^2 -10t
15 = t^2 +2t
t^2 +2t -15 = 0
(t+5)(t-3)
t = -5, 3
There's no such thing as negative time so you use the positive answer
Find the area of the figure. Round your answer to the nearest tenth.
Answer:
11.5 m^2
Step-by-step explanation:
The area of a parallelogram is base * height, so you have to find the height.
You can see on the left there's a 30 - 60 - 90 triangle with a hypotenuse of 4. Using the proportion rule, you know that the 2nd side is 4/[tex]\sqrt{3}[/tex] = [tex]4\sqrt{3}/3[/tex].
Then, find the area, so do base * height = 5 * [tex]4\sqrt{3} /3[/tex] = [tex]20\sqrt{3}/3[/tex].
Put this in a calculator and you get: 11.5 m^2

Jimmy runs 8 meters per second. His little brother runs 3 meters per second so is given a 40 meter head start. How long will it take Jimmy to catch his little brother? How far into the race will this be?
Answer:
8 Seconds
Step-by-step explanation:
Since Jimmy runs 8 meters per second, we can multiply 8x8 to find where he will be after 8 seconds.
8x8 = 64
Since Jimmy's little brother runs 3 meters per second, we can multiply 3x8 to find where he will be after 8 seconds.
3x8 = 24
But, remember, Jimmy's little brother had a 40 meter head start. So we have to add 40 to his total.
24+40 = 64
Since Jimmy and his little brother's totals are both the same, Jimmy will catch up to his little brother after 8 seconds.
