Brianna loves to compete in triathlons. At a race a few months ago, she finished in 360 minutes. At a race yesterday, she took 30% more time to finish. What was her time at yesterday's race?
Answer:
468 minutes
Step-by-step explanation:
Given data
At a race a few months ago, she finished in 360 minutes
let us find 30% of 360 minutes
=30/100*360
=0.3*360
=108 minutes
Hence she finished with an added time of 108minutes
Therefore, in all she finished in
=108+360
=468 minutes

Ren built a birdhouse with a volume of 224 in.3 Find the height of the birdhouse.
Complete question:
Ren built a birdhouse with a volume of 224 in³ Find the height of the birdhouse. A square pyramid. The square base has side lengths of 8 inches and the height is unknown.
Answer:
the height of the birdhouse is 10.5 in.
Step-by-step explanation:
Given;
volume of the square pyramid, V = 224 in³
length of a side of the square base, a = 8 in
The volume of square pyramid is calculated as;
[tex]V = \frac{a^2h}{3} \\\\where;\\h \ is \ height \ of \ the \ birdhouse \ (Pyramid)\\\\a^2h = 3V\\\\h = \frac{3V}{a^2} \\\\h = \frac{3 \times 224}{8^2} \\\\h = 10.5 \ in[/tex]
Therefore, the height of the birdhouse is 10.5 in.

Answer: P=2300 (1- 0.05)^x
Step-by-step explanation:
A Formula for calculating displacement (distance from a point) is -
[tex]s = ut + \frac{1}{2} {at}^{2} [/tex]
A) Calculate u when s = 120, a = 2 and t = 4
Answer:
s=ut +atsq/2
120=4u+4sq
4u=104
u=26m/sec
Answer:
26 m/s
Step-by-step explanation:
Given
[tex]s = ut + \frac{1}{2} {at}^{2} [/tex]
When a = 2 , s = 120 and t = 4
Then
[tex]120 = u \times 4 + \frac{1}{2} \times 2 \times {4}^{2} \\ 120 = 4u + 16 \\ 120 - 16 = 4u \\ 104 = 4u \\ u = \frac{104}{4} \\ u \: = 26

Answer:
Step-by-step explanation:
(10pts) find all the solutions to the equations.
In a right-angled triangle ,right angled at B,if AB=5cm andAC=13cm ,then BC=
Answer:
BC = 12cmStep-by-step explanation:
by phythagoras theorm
AB² + BC² = AC²
5² + BC² = 13²
25 + BC² = 169
BC² = 169 - 25
BC² = 144
BC = √144
BC = 12cm

In a certain state, license plates have 2 letters followed by 5 digits. How many different license plates
are possible if
a) digits and letters can be repeated?
b)
digits and letters cannot be repeated?
Answer: A) 26_ 26 10_10_10_10_10 = 67,600,000
B) 26_25 10_9_8_7_6 = 19,656,000
Step-by-step explanation: A) There's exactly 26 letters in the Alphabet and it wants us to repeat it, so write 26_26. Since it's also asking for a 5 digits, write 10 five times because there's only 10 digits; 0, 1, 2, 3, 4, 5, 6, 7, 8, 9. Multiply the Numbers all-together which is equals 67,600,000.
B). Again, since the License plate has 2 letters, write the Number twice. However it cannot be repeated, so write 26_25. As for the 5 digits write the Number 5 times, but it also can't be repeated, so write 10_9_8_7_6 (Use commas if you want). Then Multiply the Numbers all-together which equals 19,656,000.

A survey of teens showed that teens in Pittsburgh aged 12–17 spend 15.8 hours per week online. Teens in Miami/Ft. Lauderdale spends 14.2 hours per week online. Write and solve an additional equation to find the difference in time spent online by teens in these cities.
Answer:
1.6 hours
Step-by-step explanation:
Given that:
Time spent by Pittsburgh teens, p= 15. 8 hours
Time spent by Miami teens, m = 14.2 hours
The difference in time spent by the teens from these two cities is given by:
Time spent by Pittsburgh teens - Time spent by Miami teens
p - m
15.8 - 14.2 = 1.6 hours
