Tyron takes 5/8 hour to paint a wall. His brother takes 1/3 of the time Tyron takes. How long will his brother take to paint 5 s

suter [353]

1/3 of tyron is 1/3 of 5/8=1/3 times 5/8=5/24 hour to paint 1 wall

5/24=1 wall
tmes 5 both sides
25/24=5 walll
about 1 and 1/24 wal;
about 1hr and 2.5mins

Help would be greatly appreciated asap :)

For this, we will be using proportions. In this case, our proportion is $\frac{6}{9} =\frac{z}{15}$

Firstly, cross-multiply: $90=9z$

Next, divide both sides by 9, and your answer will be 10 = z

The ratio to dogs at the kennel is 4 to 1. there are 64 cats. how many animals are there

SIZIF [17.4K]

Let the number of cats be 4x and the number of dogs be x.

4x = 64

x = 64 ÷ 4

= 16

Total no. of animals = 4x + x

= 5x

5x = 16 × 5

Vector u has a magnitude of 5 units, and vector v has a magnitude of 4 units. Which of these values are possible for the magnitu

kumpel [21]

Answer:

Remember the triangular inequality says that if u and v are vectors then

$\lvert\lvert u + v \lvert\lvert \leq \lvert\lvert u \lvert\lvert +\lvert\lvert v\lvert\lvert$

Since the magnitude always is a nonnegative number and the magnitude of u is 5 units and the magnitude of v is 4 units ,

$0\leq \lvert\lvert u + v\lvert\lvert \leq \lvert\lvert u \lvert\lvert + \lvert\lvert v\lvert\lvert = 5+ 4 =9$

Then possibles values for the magnitude of u +v are in the interval $[0,9]$
