Answer:

ABC= 60 XYZ=540

Step-by-step explanation:

The area of a triangle is 1/2*base*height so for ABC we need to find the height first. To do this we use pythag theorem, and create the equation 13^2=5^2+height^2 rearranging this we can figure out that sqrt(height)=13^2-5^2. For the base we do 2*5 since there are two congruent line segments both equal to 5. Using this we can do 1/2*12*10=area of ABC

For XYZ we can do 1/2*30*36=area of XYZ, we can do 2*15 since there are 2 congruent 15 length line segments at the base.

Answer:

2 1/2

Step-by-step explanation:

The heaviest bag weighs 4 pounds, and the lightest bag weighs 1 1/2.

4 can be converted to 8/2 and 1 1/2 can be converted to 3/2.

8/2-3/2=5/2.

5/2 converts to 2 and 1/2 or 2.5

The heaviest bags weigh than one of the lightest bags by 2.5 pounds.

A number expressed as a quotient, in which a numerator is divided by a denominator.

The heaviest bag weighs 4 pounds,

and the lightest one weighs 3/2 pounds

The difference between the heaviest and lightest one is:

= 4-3/2

= 8/2-3/2

=5/2 pounds

= 2.5 pounds

Answer:

Step-by-step explanation:

Answer:

A is correct

Step-by-step explanation:

A has no solution because since the slopes are the same, setting both equations equal to each other will cancel out the slopes and result in 8=16, meaning no solution will make both sides equal to each other.

B does have a solution because of different slopes

C does have a solution because of different slopes

D does have a solution because of different slopes

Answer:

0.205 ; 0.117 ; 0.999

Step-by-step explanation:

Using binomial probability distribution :

P(x =x) = nCx * p^x * (1 - p)^(n - x)

Probability of success, p = 0.5

P(x = 4) = 10C4 * 0.5^4 * 0.5^6

P(X = 4) = 0.205078125

B.) 3 heads and 7 tails

P(X = 7) = 10C7 * 0.5^7 * 0.5^3

P(X = 7) = 120 * 0.0009765625

P(X = 7) = 0.117

P(atleast one head)

P(x greater than equal to 1) = p(x =1) +... P(x = 10)

Using a binomial probability calculator :

P(x greater than equal to 1) = 0.999

Answer:

[tex] x = - 3 \frac{4}{15}[/tex]

Step-by-step explanation:

[tex]2x - \frac{1}{3} + 3 = x - \frac{3}{5} [/tex]

[tex] = > 2x - \frac{ 1 +9 }{3} = x - \frac{3}{5} [/tex]

[tex] = > 2x + \frac{8}{3} = x - \frac{3}{5} [/tex]

[tex] = > 2x - x = - \frac{3}{5} - \frac{8}{3} [/tex]

[tex] = > x = - \frac{9 - 40}{15} [/tex]

[tex] = > x = - \frac{49}{15} [/tex]

[tex] = > x = - 3 \frac{4}{15} (ans)[/tex]

Answer:

x = - [tex]\frac{49}{15}[/tex]

Step-by-step explanation:

Given

2x - [tex]\frac{1}{3}[/tex] + 3 = x - [tex]\frac{3}{5}[/tex]

Multiply through by 15 ( the LCM of 3 and 5 ) to clear the fractions

30x - 5 + 45 = 15x - 9 , that is

30x + 40 = 15x - 9 ( subtract 15x from both sides )

15x + 40 = - 9 ( subtract 40 from both sides )

15x = - 49 ( divide both sides by 15 )

x = - [tex]\frac{49}{15}[/tex]

Answer:

- 8.25

Explanation:

let the unknown number be represented by x.

54 + 4x = 21

x = - 8.25

Step-by-step explanation:

The equation for continuous compounding is [tex]A=A_oe^k^t[/tex]

where [tex]A[/tex] is the final amount, [tex]A_o=[/tex] the initial amount, [tex]k=[/tex] the interest rate, and [tex]t =[/tex] how much time is affecting it.

The equation for compound interest is [tex]A=A_o(1+\frac{r}{n} )^n^t[/tex]

where [tex]A=[/tex] the final amount, [tex]A_o=[/tex] the initial amount, [tex]r=[/tex] the interest rate, [tex]n =[/tex] the number of times the interest is applied per period (usually per year), [tex]t =[/tex] how many time periods elapsed (usually how many years the interest is applied).

Therefore you must set up all the equations with their respective units. If something is decaying, it will have a negative rate or a rate < 1. If something is growing, it will have a positive rate or a rate > 1.

Answer:

5/9

Step-by-step explanation:

Let the denominator be k and thus numerator be 4 less than k or k - 4.

Fraction = (k - 4)/k

If 5 is added to both:

=> (k-4 + 5)/(k + 5) = 5/7

=> 7(k + 1) = 5(k + 5)

=> 7k + 7 = 5k + 25

=> 2k = 18

=> k = 9

Thus,

Fraction is (k-4)/k = (9-4)/9 = 5/9

There is the positive association shown in the scatter plot and the television number 3 is cost-effective and rated highly by customers.

Scatter plot is the plot of graph in which the values of two variables plotted using their coordinates on the graph.

The average rate of change is the ratio of change in y values to the change in x values of the scatter plot.

The cost and customer rating of 13 televisions is shown on the scatter plot. The televisions are rated on a scale of 0 to 10.

Here, the price and rating is increasing together in the scatter plot. Thus, there is a positive association.

Here, the television number 3 has the high rate with low price. This affect the appropriateness of using a linear regression model to fit all the data.

The television number 3 which is rated at 10 but the cost of it has just $221. Thus, the television number 3 is cost-effective and rated highly by customers.

Thus, there is the positive association shown in the scatter plot and the television number 3 is cost-effective and rated highly by customers.

How would Antonio respond....she would say "Thanks for the practice ".

Tess is right about it being easy to find 10% of 46 by moving the decimal point 1 place to the left to get 4.60.....but there is no need to do that twice....because if u do 10% twice, ur doing 20%.

okay....once u get 10% of 46 = 4.60....then u figure 5% of 46 = (0.05(46) = 2.30....because 10% + 5% = 15%.....then u add those together.....4.60 + 2.30 = 6.90. This can easily be checked...15% of 46 = 0.15(46) = 6.9 ,just like 10% of 46 + 5% of 46 = 6.9

Answer:

The quadratic function is:  [tex](x-2)(x-12)=0[/tex]    and can be written as: [tex]x^2-14x+24=0[/tex]

Step-by-step explanation:

A quadratic function can typically be written in multiple forms, among which includes: (x-a)*(x-b)=0 where a, b can be any number

This quadratic function is solved for a and b, which represents the zeroes (or can be called roots) of the equation.

Given that the zeroes are already given, all that's need to write the quadratic function is to substitute a and b with the given zeroes:

Note: It doesn't matter which zeroes are substituted for a and b

                (x-a)*(x-b)=0

               (x-2)*(x-12)=0

Now, we can leave it in this form or expand the equation (often called the FOIL method):

               (x-2)*(x-12)=0                        Multiply each term with the other terms

               [tex]x^2-2x-12x+24=0[/tex]         Simplify by combining like terms

               [tex]x^2-14x+24=0[/tex]

Thus, the quadratic function for zeroes 12 and 2 is: [tex]x^2-14x+24=0[/tex]

Answer:

14/48 Feet

Step-by-step explanation:

First, you multiply 7/8x2/3 which equals 14/24, which makes the base of the prisim 14/24 feet. Then you need to multiply 14/24 ( the base) by 1/2 (the height). 14/24x1/2= 14/48.

The final answer is 14/48.

Answer:

x = 62°

Step-by-step explanation:

the top-most angle in the top isosceles triangle must be 73° also

the third angle of the top isosceles triangle is (180 - 73 + 73) which is 34°

the left portion of the right angle must be 56°

you can find by using this equation:  x + x + 56 = 180

2x = 124

x = 62
