Samantha went running 10 days last month. The distances she ran are shown in the line plot below hows many day did Samantha run less than 56/8 miles

Answer:

B

Step-by-step explanation:

x^2 + 4x + 2 = 0; a=1, b=4, c=2

D= b^2 - 4ac = 16 - 8 = 8>0

-> x1/2= (-b +/- √D)÷2×a= (-4 +/- √8)÷2= 2(-2 +/- √2)÷2

= -2 +/- √2

×1=-2+ √2 ≈ -0.59

×2=-2- √2 ≈ -3.41

therefore, b)

Answer:

x = 3

y = 0

Step-by-step explanation:

The method of substitution is when one solves an equation for one of the variables, and then substitutes the expression into the other equation. After doing so, one will solve the other equation for the remaining variable and then backsolve for the first variable.

4x + 2y = 12

x = y + 3

The second equation is already sovled for parameter (x), subttiute this into the other equation,

4(y + 3) + 2y = 12

Distribute,

4y + 12 + 2y = 12

Simplify,

6y + 12 = 12

Inverse operations,

6y + 12 = 12

-12

6y = 0

/6

y = 0

Backsolve for (x), substitute the value of (y) into the equation for (x) and solve,

x = y + 3

x = 0 + 3

x = 3

Answer: look at the picture, sorry I can’t solve x = y + 3 for x.

Answer:

smallest   angle measure 39 degrees

Step-by-step explanation:

the sum of the three interior angles in a triangle is always 180°

x= smallest

x +x+24 + 2x = 180

4x +24 = 180

4x = 156

x = 39

Answer:

B. 39°

Step-by-step explanation:

x + 24 + 2x + x = 180 is the equation I'll use.

x + 24 + 2x + x = 180 {Step 1: Combine 2x, x, x to get 4x.}

4x + 24 = 180 {Step 2: Subtract 24 from both sides (180 - 24 = 156)}

4x = 180 - 24

4x = 156 {Step 3: Divide both sides by 4 (156 / 4 = 39)}

x = 156/4

x = 39

The smallest angle is 39°. (The other two angles are 63° and 78°, respectively.)

Answer:

Yes, the car was speeding. I agree with Nico.

Step-by-step explanation:

When you divide 98 miles by 1.7 hours, the answer is 57.6470588. I agree with Nico because it is okay to round because no matter what, the number before the decimal number (57) will always be a greater number than 55. It is easier to round the number for the equation, so Nico is correct in this situation.

Answer:

c

Step-by-step explanation:

Statement best interprets the coefficient and base of this equation  Copper production increased by a factor of 523,430x1.193 pounds per year during that period.

We have given that,

The equation c = 523, 430(1.193)

It models United States copper production in pounds from 1987 to 1992.

The pound or pound-mass is a unit of mass used in British imperial and the United States customary systems of measurement.

from the given, we have the slope is  430.

Therefore the correct option is,

Answer:

A) The area of parallelogram 1 is 4 square units greater than the area of parallelogram 2.

The area of parallelogram 1 is 2 square units greater than the area of parallelogram. Option 2 is correct.

The space filled by a flat form or the surface of an item is known as the area.

The number of unit squares that cover the surface of a closed-form is the figure's area. Square centimeters and other similar units are used to measure area.

A₁ is the area of parallelogram 1

A₁ is the area of parallelogram 2

l₁ is the distance between the points (2,6),(0,2)

l₂ is the distance between the points (4,0)(0,2)

b₁ is the distance between the points (2,0),(0,-2)

b₂ is the distance between the points (2,6),(4,-6)

A₁ =  l₁ × b₁

A₁=4.47 ×4.47

A₁  = 19.89 sq.unit

A₂=l₂×b₂

A₂=2.82 × 6.342

A₂=17.88 sq.unit

A₁-A₂ = 19.89 sq.unit - 17.88  sq.unit'

A₁-A₂= 2.01

The area of parallelogram 1 is 2 square units greater than the area of a parallelogram.

Hence,option 2 is correct.

Answer:

The Area of Δ ABC = 219.13

Step-by-step explanation:

The hard part about this problem is finding the area without the height

The formula to do this is Area = [tex]\sqrt{S(S-A)(S-B)(S-C)}[/tex]

A, B, C represent the sides

S represents [tex]\frac{1}{2}[/tex] (A + B + C)

In this equation, we will make the base be A, and the other two sides will be B and C

Sides B and C are the same length because they meet at a 90° angle

Lets plug the numbers into the variables

A = 28

B= 21

C= 21

Remember: S represents  [tex]\frac{1}{2}[/tex]  (A + B + C)

S =  [tex]\frac{1}{2}[/tex] (28 + 21 + 21)

S =  [tex]\frac{1}{2}[/tex] (70)

S = 35

Lets plug the numbers into the Area Formula now!

Area = [tex]\sqrt{35(35 - 28)(35 - 21)(35 - 21)}[/tex]

According to the order of operations, we need to do the calculations in parentheses first

35 - 28 = 7

35 - 21 = 14

35 - 21 = 14

14 x 14 x 7 = 1372

1372 x 35 = 48020

[tex]\sqrt{48020}[/tex] = 219.13

The Area of Δ ABC = 219.13

Answer:

B

Step-by-step explanation:

THIS IS HOW YOU CAN FIND ANY MISSING ANGLE - ALSO SOLVES FOR X IN THIS QUESTION.

So, a traingle is 180 degrees.

A line is also 180 degrees.

We know that the angles that make up the triangle are 46, 90, and a missing angle

We need to find the missing angle to find x

To find the missing angle, we must subtract the known angles by the 180 degrees of the traingle.

So:

180-90

=

90

90-46

=

44

So we know the missing angle is 44 degrees.

Let subtract the missing angle(44 degrees) by the 180 degrees of the line:

180-44

=

136

THIS IS WHAT ANSWERS THE OPTION METHOD THAT GIVES THE ANSWER

So x equals 136. This is the missing angle x.

So, remember, both the line and the traingle are 180 degrees.

They both need to find the missing value, which we know is 44

The rest of both the triangle and line is 136 degrees.

Well, 136 degrees on the triangle is the known 90+46 degrees.

Since this will be the same on the line, we can think of x as:

90+46

This looks like answer 1.
