Answer:63

Step-by-step explanation:

42÷2×(11-8)

We are going to resolve the bracket part first ,because bracket comes first in BODMAS,in BODMAS B=bracket O=of D=division M=multiplication A=addition S=subtraction.

After resolving the bracket part we get 42÷2×3 also in BODMAS division comes first before multiplication,so we divide and get

21×3 finally 21×3=63

Hey can you please help me

Answer:

Step-by-step explanation:

General Form of an equation of a line is given by: $y=mx+b$

Where,

m is the slope, and

b is the y-intercept (point where line cuts the y-axis)

Also, parallel lines have equal slopes.

Equation of first plane is given as $d=3.67t+4.81$

Comparing this with general form of a line, we see that 3.67 is the slope and 4.81 is the y-intercept.

The second plane is going parallel to this. So slope should be same. Hence second plane has slope of 3.67. We can write:

$d=3.67t+c$

To find the equation of second plane, we need to solve for c. Also, a point given for second plane is $(t=0, d=2.14)$ , substituting these values into the equation we got, we get the value of c:

$2.14=3.67(0)+c\\2.14=0+c\\c=2.14$

We already know m and now we know c, so we can write final equation as:

$d=3.67t+2.14$

Answer choice C is right.

Please help!!

Answer:

Α. 0

Step-by-step explanation:

Given A = -8 and B = 10

The distance between A and B

= B - A

= 10 - (-8)

= 10 + 8

= 18 units

4/9 of the way between A and B

= 4/9 of the distance between A and B

= 4/9 x 18 units

= 8 units.

Hence the location of the point that is 4/9 of the way from A to B

= value at point A + 8 units

= -8 + 8

= 0 (answer)

I need help finding if it’s either SOH, CAH or TOA and the indicated side of the triangle, thank you!

Brilliant_brown [7]

Answer:

$\huge\boxed{IJ \approx 2.01}$

Step-by-step explanation:

In order to find the side mentioned (IJ), we need to use SOH CAH TOA.

SOH CAH TOA is an acronym to help us remember what sin, cos, and tan mean. It stands for:

Sin = Opposite / Hypotenuse

Cosine = Adjacent / Hypotenuse

Tan = Opposite / Adjacent

Since we know the measure of angle K (42) and we know one of the sides, we can use this to find the missing length.

Since the side given to us is the hypotenuse, and we're looking for the side opposite of the angle (IJ), the only possible one to use would be SIN as it includes Opposite and Hypotenuse.

Our equation is now this: $\text{sin(42)} = \frac{x}{3}$

Let's now solve for x.

$\text{sin(42)} = \frac{x}{3}$
$3 \cdot \text{sin(42)} = x$
$\text{sin(42)} \approx 0.67$
$3 \cdot 0.67 \approx 2.01$

Therefore, the length of IJ will be around 2.01.

Hope this helped!
