Answer:

angle BAC is complementary to angle ACB

Step-by-step explanation:

Complementary angles add up to 90 degrees.

In a triangle, the sum of angles is 180 degrees.

ABC is a right triangle, so angles a+c=90 degrees.

Answer:

a)angle ACB

Basic facts:

angles in a triangle add up to 180

complementary angles are angles which add up to 90

Step-by-step explanation:

we can see the triangle is a right-angle triangle

if we subtract angle ABC (90 degrees)we are left with 90 degrees

therefore angle BAC and ACB add up to 90

Answer:

78.71 mph

Step-by-step explanation:

You're looking for the solution to ...

d = 88

0.0015r^2 +r = 88

0.0015r^2 +r -88 = 0

Using the quadratic formula*, we find ...

r = (-1 +√(1² -4(0.0015)(-88)))/(2×0.0015)

r = (-1 +√1.528)/0.003 = 0.236123/0.003 = 78.7077

The speed of the car was about 78.71 mph.

_____

* The quadratic formula will also give a negative answer of about -745 mph, which is not relevant to the situation.

Place the correct symbol, < or >, between the two numbers 11/18 17/24

evablogger [386]

For this case we must indicate the correct sign between the following numbers:

$\frac {11} {18}\ and\ \frac {17} {24}$

We have to:

$\frac {11} {18} = 0.611111111111\\\frac {17} {24} = 0.708333333333$

So, we have to $\frac {17} {24}> \frac {11} {18}$

Answer:

$\frac {17} {24}> \frac {11} {18}$

Callie has a new kitten. They can weigh 3 pounds less than half the weight of Callie‘s cat. Together the cat and kitten weigh 18

gavmur [86]

Answer:

The weight of cat is 14 pounds and the weight of kitten is 4 pounds.

Step-by-step explanation:

Given:

Callie has a new kitten. It can weigh 3 pounds less than half the weight of Callie‘s cat. Together the cat and kitten weigh 18 pounds.

Now, to find the weight of each animal:

Let the cat's weight be $x.$

And the kitten weight = $\frac{x}{2} -3$

Total weight of cat and kitten = 18 pounds.

Now, to set an equation to get the weight of each animal:

$(x)+(\frac{x}{2}-3)=18$

$x+\frac{x}{2} -3=18$

$\frac{2x+x-6}{2} =18$

$\frac{3x-6}{2} =18$

Multiplying both sides by 2 we get:

$3x-6=36$

Adding both sides by 6 we get:

$3x=42$

Dividing both sides by 3 we get:

$x=14\ pounds.$

The weight of cat = 14 pounds.

Substituting the value of $x$ to get the kitten's weight:

$\frac{x}{2} -3\\\\=\frac{14}{2}-3\\\\=7-3\\\\=4.$

The kitten's weight = 4 pounds.

Therefore, the weight of cat is 14 pounds and the weight of kitten is 4 pounds.
