Use the equation editor below to state how many minutes there are in 1 10 hour. Then, calculate how many minutes are equal to 5 × 1 10 hour
Answer:
Number of minutes in [tex](5\times \frac{1}{10})[/tex] hours = 30 minutes
Step-by-step explanation:
Number of minutes in 1 hour = 60 minutes
Number of minutes in [tex]\frac{1}{10}[/tex] hours = [tex]\frac{60}{10}[/tex] minutes
= 6 minutes
Therefore, number of minutes in [tex]5\times \frac{1}{10}[/tex] hours = 5 × 6
= 30 minutes
Roadsign cast of shadow that is 4 feet tall at the same time a 6 foot man standing next to the sign cast a shadow of those 2.4 feet long right and solve a proportion to find how tall the sign is
Answer:
10 feets
Step-by-step explanation:
Given that:
Road sign shadow (Rs) = 4 feets
Height of man (Hm) = 6
Man shadow (Ms) = 2.4 feets
Height of road sign (Hr) = x
Height of road sign / shadow of road sign = height of man / shadow of man
Hr/Rs = Hm / Ms
x / 4 = 6 / 2.4
Cross multiply :
4*6 = 2.4*x
24 = 2.4x
x = 24 / 2.4
x = 10 feets
Hence, height of road sign = 10 feets

1. Lizzy opened an ice cream parlor in her neighborhood selling homemade ice cream. She has a goal to create 80 new ice cream flavors. If she already created 37 flavors, how many more flavors does she still need to create?
2. A staples truck is delivering notebooks to CMS. There are 212 boxes with 198 notebooks in each box. How many total notebooks are there?
Step-by-step explanation:
2) 212*198 = 41 976
1) 80-37 = 43
9514 1404 393
Answer:
1. SCR (or PPW). 43 more flavors
2. GLT. 41,976 notebooks
Step-by-step explanation:
1. Conceptual key: SCR
Lizzy is starting with 37 flavors. She wants a result of 80 flavors, so the change can be computed from ...
37 + x = 80
x = 80 -37 = 43
Lizzy needs to create 43 more flavors.
__
Additional comment
This might also be considered to be using the PPW pattern, as both the number she has and the number she creates make up the whole number. The SCR key may better apply to cases where a "rate of change" is involved. There is no rate of change in this problem.
_____
2. Conceptual key: GLT
There are 212 groups of 198 notebooks, so the total is the number of groups times the number in each group.
(212 boxes)(198 notebooks/box) = 41,976 notebooks
Maria sells painting in a art gallery. She earns $375 each week plus a commission of 2.5% of her swelled. What is the minimum amount of sales she must have this week to earn at lease $500.
Answer:
5000.00
Step-by Step
500.00-375.00 = 125.00
5000 x 2.5% = 125.00
375.00 + 125.00 = 500.00
Mr. Smith is flying his single-engine plane at an altitude of 2400 feet. He sees a cornfield at an angle of depression of 30º. What is his horizontal distance to the cornfield?
Answer:
Height of the fighter plane =1.5km=1500 m
Speed of the fighter plane, v=720km/h=200 m/s
Let be the angle with the vertical so that the shell hits the plane. The situation is shown in the given figure.
Muzzle velocity of the gun, u=600 m/s
Time taken by the shell to hit the plane =t
Horizontal distance travelled by the shell =u

Distance travelled by the plane =vt

Qual é o comprimento do arco correspondente a um ângulo ao centro de 45 graus, numa circunferência de raio 3 cm ?
Answer:
2.4 m
Step-by-step explanation:
A fórmula para o comprimento do arco é dada como:
Comprimento do arco = 2πr (θ / 360)
Onde r = raio = 3cm
θ = Ângulo em graus = 45 °
Comprimento do arco = 2 × π × 3 (45/360)
Comprimento do arco = 2.356194m
Aproximadamente = 2.4 m
Rosario is an ecologist who studies the change in the penguin population of Antarctica over time.
The relationship between the elapsed time t, in years, since Rosario started studying the population, and
the number of penguins, P(t), is modeled by the following function:
P(t) = 21,000 • (4/7)^t/3
Complete the following sentence about the rate of change in the penguin population.
The population of penguins loses 3/7 of its size every ____ years.

Find FD(round to the nearest tenth) please and thank you!
Answer:
FD = 25.9
Step-by-step explanation:
13x - 16 = 4x + 11
9x = 27
x = 3
using Pythagorean theorem:
FD² = 12² + [4(3) + 11]²
FD² = 144 + 23² = 144 + 529 = 673
FD = 25.94
