How do you find the measures of the angles in a rhombus with the given angle 54 degrees?

Answers

Answer 1
In a rhombus, the opposite angles are equal. So if one angle is 54 degrees and the opposite angle is the same,, you have 54 + 54 = 108. All of the angles in a rhombus always add up to a total of 180 degrees, so subtract 108 from 180 to get 72 degrees. This means that the other two angles add up to 72, and since we know that opposite angles are equal, we divide 72 by 2 to get 36. This means that the measure of the angle that is adjacent to the 54 degree angle is 72 degrees. 

Hope it is helpful!
Answer 2
one angle is 54 degrees and the opposite angle is the same you add both of them together and that=108. So do 180-54 =72. This means that the other two angles add up to 72, divide 72 by 2 to get 36.   Its that easy hope that works for you. :)

Jane has read 108 pages of her book. Kevin is reading the same book and has 80 pages left to read. If there are 200 pages in the book by how much percent is the number of pages left for Jane greater then Kevin

Answers

6% because you have to subtract 108 from 200 (92) and subtract 80 from that (12) and because there is 200 pages and the percent is out of 100, you have to divide 2 by 12 and you get 6

How do you know that 6:14 is equivalent to 15:35 using a multiplication table?

Answers

Answer:Sample answer: Using a multiplication table, you would see that 6 and 15 are multiples of 3 by factors 2 and 5. You would also see that 14 and 35 are multiples of 7 by factors 2 and 5.

The required equivalency of the ratios 6:14 and 15:35 is 3 / 7 = 3 / 7.

Given that,
To determine that 6:14 is equivalent to 15:35 using a multiplication table.

What is the Ratio?

The ratio can be defined as the proportion of the fraction of one quantity towards others. e.g.- water in milk.

What is arithmetic?

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,

Here,
the given ratios are,
1) 6 : 4 = 6/4 = 2* 3/ 2 *7
2) 15:35= 15 / 35 = 5 * 3 / 5 *  7

Implies both the ratios are equivalent, by
6 : 14 = 15 : 35
2[ 3 : 7] = 5 [ 3 : 7 ]

Thus, the required equivalency of the ratios 6:14 and 15:35 is  3 / 7 = 3 / 7.

Determine the relationship between the lines that pass through the given points: line
a.(-3, 5) and (0, 7) line
b.(6, 2) and (9, 4)

Answers

a. (-3,5)(0,7)
    slope = (7 - 5) / (0 - (-3) = 2/3

y = mx + b
slope = 2/3
(0,7)...x = 0 and y = 7
sub and find b, the y int
7 = 2/3(0) + b
7 = b....this is ur y int (0,7)
so ur equation for this line is : y = 2/3x + 7

b. (6,2)(9,4)
    slope = (4 - 2) / (9 - 6) = 2/3

y = mx + b
slope(m) = 2/3
(6,2)...x = 6 and y = 2
sub and find b, the y int
2 = 2/3(6) + b
2 = 4 + b
2 - 4 = b
-2 = b...this is ur y int (0,-2)
so this equation is : y = 2/3x - 2

so " a " has a slope of 2/3 and a y int of 7 and " b " has a slope of 2/3 and a y int of -2.

ur lines are parallel lines.....parallel lines will have the same slope and different y intercepts <===

A motor racing circuit has the length of 5 5/6 milesa straight section of the circuit has the length 1 1/4 mileswhat fraction of the circuit is the straight section?

Answers

The straight section is 3/14 of the total circuit. This is mostly a problem of adjusting fractions to have common denominators. The fraction of the total circuit is ( length of straight section ) / ( length of total racing circuit ) = ( 1 1/4 ) / ( 5 5/6 ) first, convert the integer parts to a fractions with the same denominator as the fractional part: = ( (1x4)/4 + 1/4 ) / ( (5x6 / 6) + 5/6 ) combine the fractions to make a single fraction in numerator & denominator: = ( 4/4 + 1/4 ) / ( 30/6 + 5/6 ) = ( 5/4) / ( 35/6 ) the division by 35/6 can be done by instead multiplying by the inverse of 35/6: = 5/4 x 6/35 which is done by multiplying the numerators and denominators, and then simplifying by factoring out common divisors from top and bottom: = ( 5 x 6 ) / ( 4 x 35 ) = 30 /140 = 6 / 28 = 3/14

The sum of 2 consecutive numbers is 97. Find the numbers

Answers

For two consecutive numbers :

let the first number is a, and of course the next number to it would be a+1

adding these two numbers: (a) + (a+1) = 97

then solve for a:

a+a+1=97
2a+1=97
2a=96
a=48


so the first number is 48 and the second number is the next one to it (49)

The two numbers are  48 and 49

The longer leg of a right triangle is 4cm longer than the shorter leg. the hypotenuse is 8cm longer than the shorter leg. find the side lengths of the triangle

Answers

Longer leg = x + 4

Shorter leg = x

Hypotenuse = x + 8


Using Pythagorean Theorem:

a^2 + b^2 = c^2

(x + 4)^2 + x^2 = (x + 8)^2

x^2 + 8x + 16 + x^2 = x^2 + 16x + 64

2x^2 + 8x + 16 = x^2 + 16x + 64

2x^2 +8x = x^2 + 16x + 48

2x^2 - 8x = x^2 + 48

x^2 - 8x = 48

x^2 - 8x - 48 = 0

You can complete the square from here or use the quadratic formula.

Completing the square:

x^2 - 8x = 48

x^2 - 8x + (-8/2)^2 = 48 + (-8/2)^2

x^2 - 8x + 16 = 48 + 16

(x - 4)(x - 4) = 64 or (x - 4)^2 = 64

x - 4 = +√64 OR x - 4 = -√64

x - 4 = +8 OR x - 4 = -8

x = 12 OR x = -4

However, you can't use negative 4 as a length because your length needs to be a positive.

So x will be 12.


Shorter leg: 12

Longer leg: 12 + 4

Hypotenuse: 12 + 8

Final answer:

To find the side lengths of the right triangle, we let the shorter leg be x cm, resulting in the longer leg and hypotenuse being (x + 4) cm and (x + 8) cm, respectively. Using the Pythagorean theorem, we establish the equation x² + (x + 4)² = (x + 8)², then solve for x to determine the side lengths.

Explanation:

The problem involves solving for the lengths of the sides of a right triangle using the Pythagorean theorem. Let the shorter leg of the triangle be x cm. According to the problem statement, the longer leg would then be x + 4 cm, and the hypotenuse would be x + 8 cm. The Pythagorean theorem states that in a right triangle, the square of the hypotenuse (c) is equal to the sum of the squares of the other two sides (a and b).

Using the theorem we can set up the equation:

x² + (x + 4)² = (x + 8)²

Solving for x will give us the lengths of the sides of the triangle:

Shorter leg: x cmLonger leg: x + 4 cmHypotenuse: x + 8 cm

Felicity's insurance company pays for 65% of her elbow surgery, after she pays a $500 deductible.
How much will Felicity pay for her elbow surgery if it costs $9400?

A. $3290
B. $3465
C. $3615
D. $3790

Answers

C

9400 – 500(deductible)

The remainder is 8900, and the company pays for 65% of that. That means Felicity pays 35%.

35% of 8900 is 3115. Add on the 500 deductible and she pays 3615 in total.
Its going to be D. $3790
Because you first have to take 9400•0.65= 6110
Then you subtract that from the total amount and the deductible like so:
9400-6110-500=3790
And that is how you come up with D as the answer

(b/2)² = c

Answer:

The correct option is 3. c is the square of half of b.

Step-by-step explanation:

The given equations are

[tex](x+4)^2=x^2+8x+16[/tex]

[tex](x+5)^2=x^2+10x+25[/tex]

These are the perfect square. According to this pattern,

[tex](x+y)^2=x^2+2xy+y^2[/tex]           .... (1)

Each product is in the form

[tex](x+y)^2=ax^2+bx+c[/tex]         .... (2)

From (1) and (2), we get

[tex]b=2y[/tex]

[tex]c=y^2[/tex]

[tex]c=(\frac{b}{2})^2[/tex]                    [tex][\because b=2y][/tex]

It means c is the square of half of b.

Therefore the correct option is 3.

You found 6.60 on the ground at school, alpl in nickels, dimes, and quarters. you have twice as many quarters as dimes and 42 coins in all. how many of each type of coin do you have?

Answers

Let the number of nickel coins be n, the number of quarter coins be q and the number of dimes be d.

We know that 1 nickel= $0.05, 1 dime= $0.1 and 1 quarter= $0.25,


We found $6.60 means that : i) 0.05n+0.1d+0.25q=6.60

we have 42 coins in all mean: ii) n+d+q=42

we have twice as many quarters as dimes mean that iii) q=2d


using the last relation we can reduce the number of unknowns by writing all q's in terms of d's as follows:

i) 0.05n+0.1d+0.25q=6.60
ii) n+d+q=42

substitute q with 2d:

i) 0.05n+0.1d+0.25(2d)=6.60
ii) n+d+(2d)=42

i) 0.05n+0.1d+0.5d=6.60
ii) n+d+2d=42


i) 0.05n+0.6d=6.60
ii) n+3d=42

multiply the second equation by -0.2, to eliminate the d's:

i) 0.05n+0.6d=6.60
ii) -0.2n-0.6d=-8.4
---------------------------

i+ii)  

-0.2n+0.05n=6.60-8.4
-0.15n=-1.8
n=-1.8/(-0.15)=12

substitute in i):

0.05n+0.6d=6.60
0.05*12+0.6d=6.60
0.6+0.6d=6.60
0.6d=6.0
d=10


finally, from equation n+d+q=42:

12+10+q=42
22+q=42
q=42-22=20
