A building measuring 90m by60m is to be built. A paved area of uniform will surround the building. The area is to have an are of 9000 metres squared. How wide is the paved area

Answers

Answer 1

Answer: A= 9000m squared and A= base(width)*hight or A=b*h so divide 9000m by 60m
9000/60=(1050) 60 120 180 240 300 360 420 480 and so on
1 2 3 4 5 6 7 8

Similar triangles have the same angles, but don't necessarily have the same length of sides.

Determine whether the vectors u and v are parallel, orthogonal, or neither.u = <10, 6>, v = <9, 5>

Answers

$\mathbf u\cdot\mathbf v=\|\mathbf u\|\|\mathbf v\|\cos\theta$

where $\theta$ is the angle between the vectors. You have

$10*9+6*5=√(10^2+6^2)√(9^2+5^2)\cos\theta\iff \cos\theta=(30)/(√(901))\implies \theta\approx1.909^\circ$

The vectors would be orthogonal if the dot product had been zero, but that's clearly not the case.

They would be parallel if the angle turned out to be $0^\circ$ or $180^\circ$ , but that's also not the case.

So the answer is neither.

You spend $10 on office supplies out of the $25 budget what percent of your budget did you spend

Answers

Answer:

You spent 40% of your budget on office supplies.

Step-by-step explanation:

1. First take the total budget:

$25

2. Then take the money you spent on office supplies and divide it by the total budget to find the ratio you spent:

$Ratio=(10)/(25)$

$Ratio=0.4$

3. Finally multiply the ratio by a hundred to find the percentage of the budget you spent on office supplies:

$Percentage=0.4*100$

$Percentage=40$ %

Therefore, you spent 40% of your budget on office supplies.

The simplest way to find percent is to take the partial number, divide by the whole number, and multiply the answer by 100%.

$(10)/(25)$ = 0.4

0.4 x 100% = 40%.
