Answer:

[tex]A= 50[/tex]

[tex]B = 90^\circ[/tex]

[tex]C = 50^\circ[/tex]

[tex]D = 40[/tex]

Step-by-step explanation:

Given

Required

Determine A, B, C and D

The diagonals of a rhombus meet at [tex]90\ degrees.[/tex]

So:

[tex]B = 90^\circ[/tex]

Divide the rhombus into two triangles (upper and lower).

Considering the lower triangle.

Since the two sides are equal (4mm), then the triangle is isosceles.

The base angle of an isosceles triangle [tex]are\ equal.[/tex]

So:

[tex]C = 50^\circ[/tex]

Split the lower triangle into two, you get two right-angled triangles.

From one of these triangles, we have:

[tex]C + D + 90 = 180[/tex]

[tex]D = 180 - 90 - C[/tex]

[tex]D = 180 - 90 - 50[/tex]

[tex]D = 40[/tex]

Lastly, A and C are corresponding angles.

So:

[tex]A = C[/tex]

[tex]A= 50[/tex]

Answer:

mass=180kg and the volume=6m³.

then the formula to find density is= mass/volume

using this formula,180kg/6m³=30kg/m³

Answer:

8 m³

Step-by-step explanation:

Let v represent the volume.  Recall that density is mass/volume, which here is 0.9 kg/m³.  To find the volume of this object, divide the density into the mass:

 7.2 kg

--------------- = 8 m³

0.9 kg/m³

Answer:

[tex]18.5105\,\,kg[/tex]

Step-by-step explanation:

Given:

The weight of a [tex]5[/tex] gallon bottle water is [tex]18.5 \,\, kg[/tex].

The weight of a [tex]1[/tex] gallon bottle water is [tex]10,500\,\,mg[/tex]

To find:

Total weight of the two bottles of water in kg

Solution:

Weight of a [tex]5[/tex] gallon bottle water [tex]=18.5\,\,kg[/tex]

Weight of a [tex]1[/tex] gallon bottle water [tex]=10,500\,\,mg[/tex]

Use [tex]1\,\,mg=\frac{1}{1000000}\,\,kg[/tex]

So,

Weight of a [tex]1[/tex] gallon bottle water [tex]=\frac{10,500}{1000000} \,\,kg[/tex]

                                                      [tex]=0.0105\,\,kg[/tex]

Total weight of the two bottles of water in kg [tex]=18.5+0.0105=18.5105\,\,kg[/tex]

Answer:

Step-by-step explanation:

The problem is that you cannot be sure that either triangle (it actually requires both of them) contain a right angle

What you have so far is SSA which is not one of the fundamental congruency triangles. In order to be certain of congruency the angle must be made up of the 2 given sides. You are certain that SAS will produce congruency. You are not so sure of  r SSA. There are proofs of this on the internet. I urge you to look into it. Though not long, following it step by step takes a lot of patience. A cup of strong coffee is a good idea.

Answer:

16+A

Step-by-step explanation:

4*4=16

Answer:

16 + A

Step-by-step explanation:

We have the equation 4² + A and are asked to simplify.

We only have one thing to simplify here, since we can't combine "4²" and "A" due to not having the same variable ending. This would be the exponent "4²".

[tex]4^2[/tex]

[tex]16[/tex]

Therefore, this equation simplified is 16 + A

Answer:

Here walking speed is 3.5 miles per hour

Step-by-step explanation:

Here, we want to calculate the average speed in miles per hour

mathematically, we know that;

speed = distance/time

from the question, the distance is 7/10 miles

The time is 1/5 hour

Thus we have;

Speed = 7/10 divided by 1/5

speed = 7/10 * 5/1 = 7/2 = 3.5 miles per hour

Step-by-step explanation:

The first thing to do is calculate the dimensions of the pizza box. Based on our data, we know 256 = s2. Solving for s (by taking the square root of both sides), we get 16 = s (or s = 16).

Now, we know that the diameter of the pizza is four inches less than 16 inches. That is, it is 12 inches. Be careful! The area of the circle is given in terms of radius, which is half the diameter, or 6 inches. Therefore, the area of the pizza is π * 62 = 36π in2. If the pizza is 8-slices, one slice is equal to 1/8 of the total pizza or (36π)/8 = 4.5π in2.

Answer:

28.56

Step-by-step explanation:

First we need to calculate the mean average of the numbers

Average = 112+89+95+77+103/5

Average = 476/5

Average = 95.2

If Sam made 30% of goals in his last 6 games, then on average, amount made is expressed as;

Average of the last six games = 30% of 95.3

Average of the last six games  = 0.3 * 95.2

Average of the last six games = 28.56

Hence the required point average is 28.56

The table that could represent a function is given by the values

x = { 1 , 2 , 3 , 4 } and f ( x ) = { 2 , 4 , 6 , 2 } where the there exists one value in the range for every domain value.

The function rule is the relationship between the input or domain and the output or range. A relation is a function if and only if there exists one value in the range for every domain value.

A function is a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.

Given data ,

Let the function be represented as f ( x )

Now , the values of x are given as

A function is a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.

So , when x = { 1 , 2 , 3 , 4 }

The values of f ( x ) should be distinctive and no values of x should have different values for f ( x )

And , f ( x ) = { 2 , 4 , 6 , 2 } represents a function

Hence , the function is  f ( x ) = { 2 , 4 , 6 , 2 }

Answer:

divide 40 by 8cm. it's pretty self explanatory

Step-by-step explanation:

[tex]40cm \div 8cm[/tex]

divided 8 on both sides.

divide 40 from 8 and you're left with 5 cm. the length is 5.

Answer:

length = 12 cm

Step-by-step explanation:

The perimeter (P) of a rectangle is calculated as

P = 2l + 2b ( l is the length and b the breadth )

let x be the length , then

2x + 2(8) = 40

2x + 16 = 40 ( subtract 16 from both sides )

2x = 24 ( divide both sides by 2 )

x = 12

That is the length is 12 cm

The value of x is 8 units after applying the cos ratio option (D) 8 is correct.

It is a triangle in which one of the angles is 90 degrees and the other two are sharp angles. The sides of a right-angled triangle are known as the hypotenuse, perpendicular, and base.

We have a right-angle triangle shown in the picture.

As we know, Pythagoras' theorem is the square of the hypotenuse in a right-angled triangle that is equal to the sum of the squares of the other two sides.

The trigonometric ratio is defined as the ratio of the pair of a right-angled triangle.

Applying the cos ratio to find the value of x:

cos37 = x/10

x = 10cos(37)

x = 7.98 ≈ 8 units

Thus, the value of x is 8 units after applying the cos ratio option (D) 8 is correct.

Answer:

Combined volume of the two game systems  [tex]=416[/tex] cubic inches

Step-by-step explanation:

Volume of a cuboid = length × breadth × height

Soham's video game system measures 8 inches long, 6 inches wide, and 2 inches tall.

So,

Volume of Soham's video game system = 8 × 6 × 2 = [tex]96[/tex] cubic inches

As Sean's video game system measures 1 inch longer on all sides,

the video game system measures [tex]8+2=10[/tex] inches long, [tex]6+2=8[/tex] inches wide, and [tex]2+2=4[/tex] inches tall.

Volume of the video game system = 10 × 8 × 4 = [tex]320[/tex] cubic inches.

Therefore,

Combined volume of the two game systems = [tex]96+320=416[/tex] cubic inches

Given:

The function is:

[tex]y=3x^3-5x^2-11x-3[/tex]

It is given that -1 is a zero of the given function.

To find:

The other zeroes of the given function.

Solution:

If c is a zero of a polynomial P(x), then (x-c) is a factor of the polynomial.

It is given that -1 is a zero of the given function. So, [tex](x+1)[/tex] is a factor of the given function.

We have,

[tex]y=3x^3-5x^2-11x-3[/tex]

Split the middle terms in such a way so that we get (x+1) as a factor.

[tex]y=3x^3+3x^2-8x^2-8x-3x-3[/tex]

[tex]y=3x^2(x+1)-8x(x+1)-3(x+1)[/tex]

[tex]y=(x+1)(3x^2-8x-3)[/tex]

Again splitting the middle term, we get

[tex]y=(x+1)(3x^2-9x+x-3)[/tex]

[tex]y=(x+1)(3x(x-3)+1(x-3))[/tex]

[tex]y=(x+1)(3x+1)(x-3)[/tex]

For zeroes, [tex]y=0[/tex].

[tex](x+1)(3x+1)(x-3)=0[/tex]

[tex](x+1)=0[/tex] and [tex]3x+1=0[/tex] and [tex]x-3=0[/tex]

[tex]x=-1[/tex] and [tex]x=-\dfrac{1}{3}[/tex] and [tex]x=3[/tex]

Therefore, the other two zeroes of the given function are [tex]-\dfrac{1}{3}[/tex] and [tex]3[/tex].

The line which is perpendicular to 2x + 14y = 70 mus have a slope of 7/2.

A linear function is in the form:

y = mx + b

Where m is the slope and b is the y intercept

Two lines are perpendicular if the product of there slope is -1

Given the line:

2x + 14y = 70

14y = -2x + 70

y = (-2/7)x + 70

The line which is perpendicular to 2x + 14y = 70 mus have a slope of 7/2.

Answer:

D) 150 miles.

Step-by-step explanation:

The computation is shown below:

Given that

The Cost of  the car rental agency of A is $50 + 0.10 per mile

The Cost of  the car rental agency of B is $20 + 0.30 per mile

Here we assume the per mile be x

Now we equate these equations

SO,

$50 + 0.10x = $20 + 0.30x

$30 = 0.20x

x = 150

SO it would be more than 150 miles
