Solve. M/9 = 8 A m = 1.1 B m = 17 C m = 27 D m = 72

Eddi Din [679]

Answer:

D. m=72

Step-by-step explanation:

So

M/9=8
To get rid of the 9, you have to multiply both sides by 9
M/9 ×9=8×9
M=8×9
8×9=72
M=72

lauren rode her bike from her house to a friend house 3 1/3 miles away. on the first leg of her trip she rode uphill at 3 miles

spayn [35]

The uphill part of the ride would have taken 16 minutes and 40 seconds.

This can be found first by determining how many miles Lauren went during the downhill portion. This can be found by multiplying the speed by the time.

5mph * .5hrs = 2 1/2 miles.

Now we can determine how far she needs to go during the uphill portion by subtracting the downhill portion from the entire ride.

3 1/3 miles - 2 1/2 miles = 5/6 miles.

Now that we know she needs to go 5/6 miles for the uphill portion, we can divide the distance by the speed.

5/6 miles / 3 mile per hour = 5/18 hours = 16.67 mins or 16 mins and 40 seconds.

need help with error analysis assingment, im in high school and ive always struggled with math alot pls help

valina [46]

Given

A) The angles A and B are supplementary.

If,

$\begin{gathered} \angle A=x+6 \\ \angle B=7x+30 \end{gathered}$

B) The figure,

To find

A) The value of x.

B) The value of x.

Explanation:

A) It is given that,

Angle A and angle B are supplementary.

Then,

$\angle A+\angle B=180\degree$

Hence, the error is in the statement,

Since the angles are supplementary, when added together they equal 90.

As, the correct answer is when added together they equal 180.

That implies,

$\begin{gathered} x+6+7x+30=180 \\ 8x+36=180 \\ 8x=180-36 \\ 8x=144 \\ x=\frac{144}{8} \\ x=18\degree \end{gathered}$

Hence, the value of x is 18 degrees.

B) It is given that,

From, the figure the given angles are interior angles.

Also, the interior angles on the same side of the transversal is supplementary.

Which means when you add them they equal 180.

Hence, the error is in the statement,

Since the angles are adjacent, they are complementary angles.

Which means when you add them they equal 180.

As, the angles are interior angles on the same side of the transversal.

Also,

$\begin{gathered} 64+x=180 \\ x=180-64 \\ x=116\degree \end{gathered}$

Hence, the value of x is 116 degrees.

2. Find the number of distinct triangles with c=11,b=7,B=18 a.0 b.1 c.2 d. cannot be determined

jok3333 [9.3K]

Answer: Choice C) 2

----------------------------------------------

Explanation:

Using the law of sines, we get
sin(B)/b = sin(C)/c
sin(18)/7 = sin(C)/11
0.0441452849107 = sin(C)/11
11*0.0441452849107 = sin(C)
0.4855981340177 = sin(C)
sin(C) = 0.4855981340177
C = arcsin(0.4855981340177) or C = 180-arcsin(0.4855981340177)
C = 29.0516679549861 or C = 150.948332045013
There are two possibilities for angle C because of something like sin(30) = sin(150) = 1/2 = 0.5

Those approximate values of C round to
C = 29.05 and C = 150.95

If C = 29.05, then angle A is
A = 180-B-C
A = 180-18-29.05
A = 132.95
Making this triangle possible since angle A is a positive number

If C = 150.95, then angle A is
A = 180-B-C
A = 180-18-150.95
A = 11.05
making this triangle possible since angle A is a positive number

There are two distinct triangles that can be formed.
One triangle is with the angles: A = 132.95, B = 18, C = 29.05
The other triangle is with the angles: A = 11.05, B = 18, C = 150.95
The decimal values are approximate
