Answer:

7.5km/h

Step-by-step explanation:

Given data

Distance= 15km

Time = 2 hours

We know that the expression for the speed is

Speed= distance/time

Substitute

Speed= 15/2

Speed= 7.5 km per hour

Hence the speed is 7.5km/h

Step-by-step explanation:

In the case when we multiplied 0.014 by 100,000 so it comes

= 0.014 × 100,000

= 1,400

Since The value 0.014 were times by 5 zeros.

Therefore the decimal point would move 5 places to the right

Answer:

A. you won't have enough

   1/8 x 6 = 6/8 of a teaspoon

   you have 2/3 teaspoon of black pepper set it equal and get a common denominator

6/8 = 2/3 --------------->  18/24 = 16/24 so you dont have enough

Ok so you have 2 pies.

You can cut into quarters which is 4 slices in 1 pie.

Than you can do 4 slices x 2 pies which means you have 8

Answer:

120°

Step-by-step explanation:

From the question,

The expression for the dot product of two vector is given as

a.b = abcosθ................... Equation 1

make θ the subject of the equation

θ =cos⁻¹ (a.b/ab)......................... Equation 2

Where θ = angle between the vector.

Given: a.b = -27, a = 6, b = 9

Substitute these values into equation 2

θ = cos⁻¹[-27/(6×9)]

θ = cos⁻¹(-27/54)

θ = cos⁻¹(-0.5)

θ = 120°.

Hence the angle between the vector is 120°

Answer:

46.6°

Step-by-step explanation:

A slide at a children's park is 74 inches tall in the horizontal distance The slide covers is 70 inches what is the angle measures created by the slide and the ground

We solve the above question using Trigonometric function of Cosine.

tan x = Opposite/Adjacent

x = The angle

Hypotenuse = Slide covers = 70 inches

Adjacent = 74 inches

tan x = 74/70

x = arc tan (74/70)

x = 46.591140271°

Approximately = 46.6°

Step-by-step explanation:

I DID IT ON A CALCULATOR

The area of a 2D form is the amount of space within its perimeter. The area that is needed to be mowed by Brian is 2.07 acres.

The area of a 2D form is the amount of space within its perimeter. It is measured in square units such as cm2, m2, and so on. To find the area of a square formula or other quadrilateral, multiply its length by its width.

The total area that is needed to mow is 7.84 acres. Given that Brian mows 1.291 acres on Monday, 0.85 acres on Tuesday, and 3.63 acres on Thursday. Therefore, the area already mowed by Brian can be written as,

[tex]\rm \text{The area already mowed by Brian} = 1.291 + 0.85 + 3.63= 5.771\ acres[/tex]

The area that is left to mow = Total area - Area already mowed by Brian

                                              = 7.84 - 5.771

                                              = 2.069 acres ≈ 2.07 acres

Hence, the area that is needed to be mowed by Brian is 2.07 acres.

Answer:

1)

Step-by-step explanation:

In the line that is the graph of equation x = 2, every ordered pair has 2 as its x-coordinate. That means it's a vertical line that passes through x = 2 on the x-axis.

Answer: 1)

The graph option 1) is the correct answer.

An equation is a mathematical statement that shows that two mathematical expressions are equal.

Given is an equation, x = 2

We see x intercept is 2 and there is no y intercept,

We know when x = a then the line is always parallel to y-axis and here x intercept is 2 therefore the line will pass through 2 on x-axis.

In graph 1) The line is passing through 2 on x-axis and is parallel to y-axis.

Hence, The graph option 1) is the correct answer.

Answer:

d = 11 units if rounded to nearest whole number

Step-by-step explanation:

Distance formula:

d=√((x_2-x_1)²+(y_2-y_1)²)

Your ordered pairs (-1, 1) and (4, 11)

d=√((4-(-1))²+(11-1)²)

d=√((4+1))²+(10))²)

d=√((5)²+ 100)

d = √125

d = 11.18  

d = 11 units if rounded to nearest whole number

Final Step: Biggest Common Factor Number

We found the factors and prime factorization of 36 and 56. The biggest common factor number is the GCF number.

So the greatest common factor 36 and 56 is 4.

The highest common factor of 36 and 56 is 4 after using division algorithm, the answer is 4.

It is defined as the common number of two integers, which is the lowest number that is a multiple of two or more numbers. The full name of LCM is the least common multiple.

It is given that:

The two numbers are: 36 and 56

As we know GCF means highest common factor, the factor which presents the in both numbers:

The GCF(36, 56) can be found using the Division Lemma:

56 = 36x1 + 20

36 = 20x1 + 16

20 = 16x1 + 4

16 = 4x4 + 0

The value of GCF(36, 56) :

GCF(36, 56)  = 4

Thus, the highest common factor of 36 and 56 is 4 after using division algorithm, the answer is 4.

Answer:

$60.00 * 1.075 * .6 + 5.99 = $44.69

when you have multiple fees and discounts and taxes and whatever else, you should follow the order of all operations.  multiplication and division before addition and subtraction, and so on.  

Step-by-step explanation:

For discount and sales tax you multiply, and for shipping you just add the fee.  We will save shipping for last since it doesn't effect the discount or tax.  Meanwhile you could apply the discount and tax in any order.

To apply a discount you take the price and multiply by 1 minus the percent in decimal form.  decimal form of a percent is basically the number divided by 100.  so 40% = .4 then 1 - .4 = .6

to apply a ttax you multiply 1 plus the percent in decimal form.  tax is 7.5% so in decimal form that's .075 then 1 plus the tax is 1.075

so now you multiply 60 * .6 * 1.075 and also remember 60 * .6 * 1.075 = 60 *  1.075 * .6 but the answer is $38.70

Now add the shipping, so 38.70 + 5..99 = $44.69

  (b)  (1, 1/6)

Step-by-step explanation:

The "unit rate" is always the y-value for x=1 when the relationship is proportional (as it is here).

That point is not specifically shown on the graph. It would be (1, 1/6).

$3.68 for 16 pens

$3.68 per 16 pens

($3.68) / (16 pens)  

$0.23 / (1 pen)

$0.23 / pen

$0.23 per pen

I am not 100% sure sorry

Regular - $0.34

Rounded- $0.30

Explanation:

to find unit rate, set up the problem like a fraction. put the total cost on top, and the number of pens in a pack on bottom. Divided by the number of pens in the pack, which is 16. The answer will be the unit rate.

FOR EXAMPLE:

5.44/16 DIVIDED BY 16.

on the bottom you would get one because 16 divided by 16 is one. And on the top it would be 5.44 divided by 16 which is $0.34.

Given:

[tex]b(1)=-12[/tex]

[tex]b(n)=b(n-1)\cdot 4[/tex]

To find:

The third term of the sequence.

Solution:

We have,

[tex]b(n)=b(n-1)\cdot 4[/tex]

For n=2, we get

[tex]b(2)=b(2-1)\cdot 4[/tex]

[tex]b(2)=b(1)\cdot 4[/tex]

[tex]b(2)=-12\cdot 4[/tex]              [tex][\because b(1)=-12][/tex]

[tex]b(2)=-48[/tex]

For n=3, we get

[tex]b(3)=b(3-1)\cdot 4[/tex]

[tex]b(3)=b(2)\cdot 4[/tex]

[tex]b(3)=-48\cdot 4[/tex]              [tex][\because b(2)=-48][/tex]

[tex]b(3)=-192[/tex]

Therefore, the 3rd term of the sequence is -192.
