Answer:

64.4 mph

Step-by-step explanation:

Speed is distance traveled over time.

Distance = 290 miles

Time = 4.5 hours

290/4.5 = 64.4

Answer:

64.44mph

Step-by-step explanation:

If Sally drives 290 miles in 4.5 hours, then how many can she drive in one hour?

speed=distance/time

290/4.5=64.44

Sally drives at an average speed of 64.44 miles per hour.

Answer:

The area of shaded region

[tex]4x^2+4x+6[/tex]

Step-by-step explanation:

We are given that  the area of rectangle

[tex]13x^2-4x+10[/tex]

The area  of trapezoid represented by

[tex]9x^2-8x+4[/tex]

We have to find the expression to represent the area of the shaded region.

To find the area of shaded region we will subtract the area of trapezoid from the area of rectangle.

Therefore, the area of shaded region

Area of rectangle-Area of trapezoid

[tex]13x^2-4x+10-(9x^2-8x+4)[/tex]

[tex]13x^2-4x+10-9x^2+8x-4[/tex]

[tex]4x^2+4x+6[/tex]

Hence, the area of shaded region

[tex]4x^2+4x+6[/tex]

Answer:

13 pints.

Step-by-step explanation:

1 US liquid quart = 2 US liquid pint

6.5 quarts = how many pints?

Cross multiplying gives:

× 2 pints = 13 pints

Answer:

11 pints

Step-by-step explanation:

Each gallon is 4 quarts, and each quart is 2 pints. If a quart is 2 pints, then half a quart is 1 pint. Basically to convert, you just multiply the amount of quarts by two, and then that's the number of pints. 5 1/2 times 2 is 11, so 5.5 quarts is 11 pints.

Use PEMDAS

Parenthesis,Exponent,Multiplication,Division,Addition,Subtraction

Step 1

2(x+5)=(x-4)  Equation/Question

Step 2

2(x+5)=(x-4)  Remove parenthesis

2x+10=x-4

Step 3

2x+10=x-4  Subtract 1x from sides

x+10=-4

Step 4

x+10=-4  Subtract 10 from sides

answer

x=-14

Answer:

x+6

Step-by-step explanation:

to find f(-x) plug in -x for all the values of x in the equation

since the absolute value of -x is x you get x+6

Answer:

6 - 5d is an expression equivalent to -5d + 6 using the commutative Property of Addition.

Step-by-step explanation:

Commutative Property of Addition

We know that we can add two numbers in any order.

For example,

Let 'a' and 'b' be two numbers.

We can add  'a' and 'b' numbers in any order, such as

a + b = b + a

Thus,

a + b = b + a is represented using the commutative Property of Addition.

In our case,

-5d + 6 can be written or represented using the commutative Property of Addition, such as

-5d + 6 = 6 - 5d

It is clear that -5d + 6 can be written in any order such as 6 - 5d.

In other words, 6 - 5d is an expression equivalent to -5d + 6 using the commutative Property of Addition.

Therefore, 6 - 5d is an expression equivalent to -5d + 6 using the commutative Property of Addition.

Answer: $2,150

Step-by-step explanation:

The amount taken was $2,000

The interest rate was 2.5%

Period is 3 years.

The formula for simple interest is:

= Amount * ( 1 + rate * time)

= 2,000 * ( 1 + 2.5% * 3)

= $2,150

Answer:

  [tex]\dfrac{2}{3}x-\dfrac{13}{12}=-\dfrac{5}{12}x[/tex]

Step-by-step explanation:

There are a couple of ways to get equivalent equations. We can collect the constants on one side of the equal sign, or we can collect the variable terms on one side of the equal sign.

Constants:

  [tex]\dfrac{2}{3}x-\dfrac{5}{6}=-\dfrac{5}{12}x+\dfrac{1}{4} \qquad\text{given}\\\\ \dfrac{2}{3}x-\dfrac{10}{12}-\dfrac{3}{12}=-\dfrac{5}{12}x \qquad\text{subtract $1/4=3/12$}\\\\ \dfrac{2}{3}x-\dfrac{13}{12}=-\dfrac{5}{12}x \qquad\text{matches last choice}[/tex]

Note that if we add 13/12 to this equation, the constant will be on the right, as in the second choice. However, that constant will be 13/12, not -7/12, so the second choice is not equivalent.

__

Variable terms:

  [tex]\dfrac{2}{3}x-\dfrac{5}{6}=-\dfrac{5}{12}x+\dfrac{1}{4} \qquad\text{given}\\\\ \dfrac{8}{12}x+\dfrac{5}{12}x-\dfrac{5}{6}=\dfrac{1}{4} \qquad\text{add $\dfrac{5}{12}x$}\\\\ \dfrac{13}{12}x-\dfrac{5}{6}=\dfrac{1}{4} \qquad\text{not equivalent to 3$^{\text{rd}}$ choice}[/tex]

Note that if we subtract 13/12x from both sides of this equation, the x-term will be on the right, as in the first choice. However, it will be -13/12x, not 1/4x, so the first choice is not equivalent, either.

The last offered choice is the equivalent equation.

First, make an equilateral triangle and label all the points. All the line segments that have a ratio of 1, mark those as congruent and all the line segments that have a ratio of 3, mark those congruent as well. Now, what we can is 3 congruent triangles by SAS, (AMK = BPM = CKP). Then, we take MP, PK, and KM and we know those are congruent because of CPCTC. That means all the sides are equal in the inner triangle which means it is an equilateral triangle.

Answer:

Difference = 62.5 micrometer

Step-by-step explanation:

Given that:

Diameter of red blood cell = 7.5 micrometer

Diameter of coarse grain of sand = 70 micrometers

For calculating the difference between two diameters, we will subtract the diameter of red blood cell from diameter of grain of sand.

Difference = 70 - 7.5

Difference = 62.5 micrometer

Hence,

Difference = 62.5 micrometer

Step-by-step explanation:

Answer:

Step-by-step explanation:

1). ∵ 1 L = 1000 ml

   ∴ 4 L = 4000 ml

2). ∵ 1 cm = 10 mm

    ∴ 5 cm = 50 mm

3). ∵ 1 mg = 0.1 cg

    ∴ 5 mg = 0.5 cg

4). ∵ 1 ml = 0.001 L

    ∴ 25 ml = 0.025 L

5). ∵ 1 gm = 1000 mg

    ∴ 0.125 gm = 25 mg

6). ∵ 1 ml = 0.001 L

    ∴ 570 ml = 0.57 L

7). ∵ 1 mm = 0.1 cm

    ∴ 135 mm = 13.5 cm

8). ∵ 1 mg = 0.001 g

    ∴ 1820 mg = 1.82 g

9). ∵ 1 g = 100 cg

    ∴ 0.5 g = 50 cg

10). ∵ 1 ml = 0.001 L

     ∴ 0.2385 ml = 0.0002385 L
