Answer:

m<w= 36°

Step-by-step explanation:

Step 1) Applying geometric and algebraic knowledge, the two angles to the left are both 90, and equal to 180. If you add those two angles and the 146°, you will be given 326 in total.

90+90= 180 +146 = 326

Step 2) With knowledge that the sum of all interior angles inside of a quadrilateral add up to 360, subtract 326 from this.

360-326=36

Final product: m<w=36°

Answer:40

Step-by-step explanation: because 70 times 2 = 140 and you add 40 will equal 180 because every triangle equals 180

The measure of angle m<P is 40 degrees

The given triangle is an isosceles triangle where:

m<R = m<Q

Taking the sum of the interior angles, we will have:

m<P + ,m<Q + m<R  = 180

70 + 70 + m<P = 180

m<P = 180 - 140

m<P= 40 degrees

Hence the measure of angle m<P is 40 degrees

Answer: One triangle

Step-by-step explanation:

-The triangle's dimensions are defined and fixed.

-Given the fixed dimensions, only one unique triangle can be constructed.

-Hence, only one triangle of the dimensions 7.2cm, 6.9cm and 12.8 cm can be formed.

Answer:

1

Step-by-step explanation:

The correct shape would be a scalene triangle, which can't be bent and twisted and still have the same side lengths.

Step-by-step explanation:

m = (y2-y1)/(x2-x1)

m = (4-0)/(0-(-8))

m = 4/8

y = mx + c

4 = (4/8)(0) + c

c = 4

Thus, the equation is y = (4/8)x + 4

Answer:

9:22

Step-by-step explanation:

Find the LCM Least common multiple of all three numbers (minutes)

3,4,5  LCM is 60

Divide each one into the LCM

60/3 = 20

60/4 =  15

60/5 =  12

Totals =82

add that to the time 8:00

82 is an Hour and 22 minute so it would be 9:22

Given :

You decide to run at least 7.5 miles per week during the week to train for the cross-country season in the fall.

During one week, you run 2 miles on Sunday and 2.5 miles on Wednesday.

To Find :

How many more miles, m, do you need to run before the week is over.

Solution :

Total number of miles we travelled till Wednesday :

t = miles run on Sunday + miles run on Wednesday

t = 2 + 2.5 miles = 4.5 miles.

Now, number of miles remaining :

R = Total target - t

R = 7.5 - 4.5 miles

R = 3 miles.

Therefore, we need to run 3 more miles before the week is over.

Hence, this is the required solution.

Answer:

No, these equations are not parallel.

Step-by-step explanation:

The equation [tex]y=0[/tex] is a vertical line. This equation, in fact, is the y-axis.

The equation [tex]x=0[/tex] is a horizontal line. This equation, in fact, is the x-axis.

These lines are perpendicular, not parallel.

Answer:

0,1-0,9

-0,8

Step-by-step explanation:

Subtract the second point from the first point.

Let the shorter piece be x. The longer piece is 4 times the length of the other, so it is 4x.

4x + x = 160.

5x = 160

x = 32

4x = 128

The length of the shorter piece is x, which is 32.

Answer:

Indirect variation

Step-by-step explanation:

If two variables change in inverse proportion, then it is called indirect variation.

xy = k where k is a constant.

5*2 = 10

10*1 =10

[tex]15*\dfrac{2}{3}=5*2=10\\\\\\20*\dfrac{1}{2}=10[/tex]

So, this is indirect variation.

Answer:

The first one should be the answer. 90 degrees counterclockwise.

Answer:

See below.

Step-by-step explanation:

The answer would be 90 degrees counterclockwise. Think of a clock. The direction it usually goes is clockwise. The opposite direction is counterclockwise. So, this triangle rotated counterclockwise.

Answer: He has used up 117 calories.

Step-by-step explanation:

Given, For 62% as factor, calories burned (E)= (weight)(0.62).

Also, if they run an 8-minute mile, the factor is 65%.  [given]

Then, calories burned (E)= (weight)(0.65). [65%=0.65]

Weight of man = 180 lb

Then, calories burned (E)= 180 x (0.65).

= 117

Thus , he burned 117 calories.

So, he has used up 117 calories.

Answer: 32ft²

Step-by-step explanation:

The area of a trapezoid is given by the formula: A = [(b1+b2)/2] x h, where b1 and b2 are the two bases, and h is the height.

In our situation, b1 = 3, and b2 = 5. The height is given as 2.

Plugging these numbers into our formula:

A = (b1+b2)/2 x h

A = [(3+5)/2] x 2

A = (8/2) x 2

A = 4 x 2

A = 8ft²

8ft² is the area of one trapezoid. If Mr. Smith wants to fit 4 of these shapes into the room, the combined area will be 4 x 8 = 32ft².

Have a nice day :)

Answer:

[tex]\frac{12}{49}[/tex]

explanation:

Use the keep change flip method. This consists of literally flipping a fraction to make the denominators alike, allowing for faster solves and multiplication.

[tex]2\frac{1}{3}[/tex] is [tex]\frac{7}{3}[/tex], so flip 7/3 so it is 3/7, matching up with 4/7.

Next, multiply.

4 x 3

7 x 7

4 x 3 is 12. Write 12 as a numerator.

7 x 7 is 49. Write 49 as a denominator.

Therefore, the answer is [tex]\frac{12}{49}[/tex]

Simplifying? We cannot simplify this number due to a lack of factors.

Since it's 20% off that means subtraction

700-140=560

Answer:

The truck will need to make 3 trips.

Step-by-step explanation:

First, we need to find the volume that the truck can carry. Using the dimensions of the truck and the volume formula, we have:

[tex]V=lwh\\V=8.5\times5\times3.5\\V=148.75\text{ ft}^3[/tex]

Since we need to move a total of 400 cubic feet, we will divide that amount by the truckload capacity (volume).

[tex]400 \div 148.75 \approx 2.689[/tex]

In context, he will need to take three truck loads: two loads will be full, and the third will not be full.

Answer:

x = 1 and x = 3

Step-by-step explanation:

Let's solve your system by substitution.

y=2x+1;y=3x

Step: Solvey=2x+1for y:

y=2x+1

Step: Substitute2x+1foryiny=3x:

y=3x

2x+1=3x

2x+1+−3x=3x+−3x(Add -3x to both sides)

−x+1=0

−x+1+−1=0+−1(Add -1 to both sides)

−x=−1

−x

−1

=

−1

−1

(Divide both sides by -1)

x=1

y=2x+1

y=(2)(1)+1

y=3(Simplify both sides of the equation)
