Simplify. 3√-28
A 2i√7
B 12i√7
C 61√7
D -6i√7
Answer:
C
Step-by-step explanation:
We want to simplify the expression:
[tex]\displaystyle 3 \sqrt{-28}[/tex]
Rewrite:
[tex]\displaystyle = 3 \sqrt{ 4\cdot 7 \cdot -1}[/tex]
Rewrite:
[tex]\displaystyle = 3 \cdot \sqrt{4} \cdot \sqrt{7} \cdot \sqrt{-1}[/tex]
Simplify. Let i = √(-1). Hence:
[tex]\displaystyle = 3 \cdot \left(2\right) \cdot \left(i\right) \cdot \sqrt{7}[/tex]
Multiply:
[tex]\displaystyle = 6i\sqrt{7}[/tex]
In conclusion, our answer is C.

One year, an athlete won a gold medal with a long jump of some
meters. Several years later, another athlete won a gold medal with a
long jump of 7.12 meters. The second jump was 0.13 meters longer
than the first. How long was the first jump? Write an equation
and solve.
Answer:
6.99 meters
Step-by-step explanation:
For this we have to use subtraction:
So if the second jump was .13 meters longer then the first and we know the second jump was 7.12 meters, we have to subtract 7.12 by .13 to get the length of his/her's first long jump. So our equation is 7.12-.13=length of first jump. So we end up getting 6.99=length of first jump.
Hope this helps! :D
Which equation is represented by the graph?

Step-by-step explanation:
Three years back, afather was 24 years older than his son at present the father is 5 times as old as the son how old will the son be three years from now?
Answer:
Let current age of father be x and current age of his son be y.
So 3 years ago, difference between their age was 24.
Therefore equation becomes
(x-3)-(y-3) = 24.
x - y = 24.
At present father is 5 times as old as son.
x = 5y.
Therefore 5y - y = 24.
y = 6.
Current age of son is 6 years. So after three years he will be 9 years old.

if the actual distance from San Antonio to Houston is approximately 188 miles use the length of the line segments indicated in the figure along with the similar triangles to approximate.
a: The actual distance from Dallas to Houston = _ miles
b: The actual distance from Dallas to San Antonio = _ miles
9514 1404 393
Answer:
a) 235 mi
b) 259 mi
Step-by-step explanation:
The scale factor from the map to the real world is apparently ...
(SA-H actual)/(SA-H map) = (188 mi)/(3 in) = 62 2/3 mi/in
Then the actual distance from Dallas to Houston is ...
(3.75 in)(62 2/3 mi/in) = 235 mi
And from Dallas to San Antonio, the distance is ...
(4.125 in)(62 2/3 mi/in) = 258.5 mi ≈ 259 mi

m∠AKD = 46°
Step-by-step explanation:
Answer:
<AKD = 46°Step-by-step explanation:
Given,
Measure of <AKG = 133°
So,
<AKG = <AKD + <DKG (As both together combine to form one <AKG as shown)
=> 133° = <AKD + 87°
=> <AKD = 133° - 87°
=> <AKD = 46° (Ans)

Answer:
3300
Step-by-step explanation:
P = 3/4n + 1800
P = 3/4(2000) + 1800
P = 3 × 500 + 1800
P = 1500 + 1800
P = 3300
Therefore, the cost of producing 2000 items is GHC 3,300.
cost of producing 2000 items =3300
Solution:-
P = 3/4n + 1800
P = 3/4(2000) + 1800
P = 3 × 500 + 1800
P = 1500 + 1800
P = 3300
Therefore, the cost of producing 2000 items is GHC 3,300.

2. 1000 tickets were sold for a school play. The regular price tickets were $5. Tickets for reserved seating was $2 more. The box office took in a total of $5300. How many tickets of each type were sold?
Answer:
1. (6,3)
2. x = 850, y = 150
Step-by-step explanation:
1. 3x-5y=3
4x-15y=-21
-9x +15y=-3 (multiply by -3)
4x-15y=-21
-5x=-30
x = 6
3(6)-5y=3
18-5y=3
-5y= -15
y= 3
so, x = 6, y = 3
2.
let x be regular
let y be reserved
x+y=1000
x= 5, y= 5+2=7 ("2 dollar more")
5x+7y=5300
x+y=1000
use the elimination method
x=850, y=150
so, the regular tickets were 850 and reserved tickets were 150 sold.
a recipe which yields 5 serving calls for 2 cups of milk. how many cups of milk are needed to make 9 servings?
Answer:
3.6 cups of milk
Step-by-step explanation:
Create a proportion where x is the number of cups of milk needed for 9 servings:
[tex]\frac{5}{2}[/tex] = [tex]\frac{9}{x}[/tex]
Cross multiply and solve for x:
5x = 18
x = 3.6
So, 3.6 cups of milk are needed to make 9 servings.

If angle DEG is 8x + 14 and angle GEF is 8x - 7, the measure of angle DEG is ___ degrees.
Answer:
100.5
Step-by-step explanation:
As it's a straight line, the angles should add up to 180. So 8x+14+8x-7=180, 16x+7=180, x=10.8125, DEG will be 8x+14=100.5
Taylor and Anya live 36 miles apart.On Some Saturdays.They ride theirs Bikes toward each other's houses and meet somewhere in between. Taylor is very Consistent rider she finds that her speed is always close to 12.5 miles per hour.Anya rides more slowly than Taylor, but she is working out and is becoming a faster rider as the weeks go by.On a Saturday in July, the two friends set out on their bikes at 8 a.m.Taylor rides at 12.5 per hour and Anya rides at 5.5 miles per hour.After one hour, how far apart are they? Show your work and Explain your Answer.
At What Time will the two friends meet?How do you know? Show your Work and Explain your Answer.
Answer:
Taylor and Anya will meet at 10:00 a.m.
Step-by-step explanation:
If Taylor rides at 12.5 mph (miles per hour), and Anya rides at 5.5 mph (miles per hour), then we need to combine these ratios to see how far apart they will be in one hour.
12.5 mph + 5.5 mph = 18 miles
Therefore, after an hour, Anya and Taylor are 18 miles apart.
Since there houses are 36 miles apart, and 18 x 2 = 36, then we can infer that it will take two hours, two times the time it took for them to finish halfway of their journey, for them to meet.
8:00 a.m. + 2 hours = 10:00 a.m.
Therefore, Taylor and Anya will meet at 10:00 a.m.
