Answer:

If you have SSA, then the third side determines the triangle. If it is too short to intersect the other side, then it does not form a triangle.

Answer:

x=9

Step-by-step explanation:

These angles are equal to each other because they are alternate exterior angles. Thus, we can solve the for the value of x by creating the equation

6x+5=7x-4

From here, we solve it like a normal algebraic equation, isolating the variables and making sure it is on the same side of the other. From there we subtract 7x from both sides, and subtract 5 from both sides, leaving -x = -4-5. Summing up -4-5, we get -x=-9. Now we make them positive on both sides, leaving the answer that x = 9

Answer:

he traveled a total of 349.5 miles.

Step-by-step explanation:

*First we convert the 150 minutes to hours, that is :

[tex]h=\frac{1.150}{60} \\h=2.5[/tex]

Now we determine the distance Michael traversed during those 2.5 hours:

[tex]d_{1} =2.5.75 \\d_{1} =187.5\\[/tex]

He transversed 187.5 miles.

We also determine the distance he tranversed the two remaining hours:

[tex]d_{2} =2.81 \\d_{2} =162[/tex]

He also traveled 162 miles

Finally we add both traversed distances:

[tex]d_{t}=187.5+162 \\d_{t} =349.5\\[/tex]

So , he traveled a total of 349.5 miles.

Answer:3.55 liters of paint are in each container

Step-by-step explanation:

Total amount of paint ( purple paint ) =Amount of red paint + Blue paint

= 6.42 Liters + 6.87 Liters

=13.29Liters

Amount of paint in the three containers = Total amount of paint ( purple paint ) - amount left over = 13.29- 2.64

=10.65Liters

Amount OF Paint in each container = Amount of paint in the three containers / 3

10.65/ 3

=3.55 liters

Answer:

3000 feets

Step-by-step explanation:

Given that :

Initial Ascent to steady altitude = 35,000 feets

Descent to steady altitude = 32,000 feets

Number of feets the plane descend :

(Initial ascent to steady altitude - descent to steady altitude)

(35000 - 32000) feets = 3,000 feets

Step-by-step explanation:

y = 1 / (cx + a) - b

At the x-axis intercept, y = 0.

=> 1 / (cx + a) - b = 0

=> 1 / (cx + a) = b

=> b(cx + a) = 1

=> bcx + ab = 1

=> bcx = 1 - ab

=> x = (1 - ab) / (bc)

Hence the answer is Option B.

Answer:

       0.59 < 0.6

14.807 < 14.087

Step-by-step explanation:

all the bolded ones are correct

The correct comparisons are 0.59 < 0.6, 6.580 = 6.58 and 4.59 < 4.598.

Decimals are types of real numbers where the fractional number is simplified by base-10 number system. It involves a whole number part and a decimal part separated by a decimal point.

Any whole number 'a' can be written as decimal as a.00...

The first place value after the decimal point is called tenths, second value is called hundredths, third value is called thousandths and so on.

The comparison 0.59 < 0.6 is true, since the tenths of 0.59 is 5 which is less than the tenths of 0.6, which is 6.

The comparison 6.580 = 6.58 is also true, since the zeroes on the last after decimal point have no value.

The comparison 33.54 < 33.504 is false, because the hundredths of 33.54, 4, is greater than the hundredths of 33.504 which is 0.

The comparison 14.807 <14.087 is false, because tenths of 14.807 is 8 which is greater than the tenths of 14.087, which is 0.

The comparison 4.59 < 4.598, because the thousandth of 4.59 can be told as 0 which is less than the thousandths of 4.598, which is 8.

Hence  0.59 < 0.6, 6.580 = 6.58 and 4.59 < 4.598 are the correct comparisons given.

Solving the equation for all real solutions in simplest form.

[tex]z^2 - 12z +9= -3[/tex] we get [tex]\mathbf{z=10.9\: or\: z=1.1}[/tex]

Step-by-step explanation:

We need to solve the equation for all real solutions in simplest form.

[tex]z^2 - 12z +9= -3[/tex]

First simplifying the equation:

[tex]z^2 - 12z +9+3= -3+3\\z^2 - 12z +12= 0[/tex]

Now, we can solve the equation using quadratic formula:

[tex]z=\frac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]

we have a = 1, b=-12 and c=12

Putting values in formula and finding values of x

[tex]z=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\\z=\frac{-(-12)\pm\sqrt{(-12)^2-4(1)(12)}}{2(1)}\\z=\frac{12\pm\sqrt{144-48}}{2}\\z=\frac{12\pm\sqrt{96}}{2}\\z=\frac{12\pm9.8}{2}\\z=\frac{12+9.8}{2}\:or\:z=\frac{12-9.8}{2}\\z=10.9\:or\:z=1.1[/tex]

So, we get value of z: z=10.9 or z=1.1

Solving the equation for all real solutions in simplest form.

[tex]z^2 - 12z +9= -3[/tex] we get [tex]\mathbf{z=10.9\: or\: z=1.1}[/tex]

Answer:

No

Yes

No

Yes

Step-by-step explanation:

In the first 1, the input 2 repeats which makes it not a function

in the second one each input is unique and does not repeat so it is a function

in the third one the input 1 repeats and makes it not repeat

And in the last one each input is unique

If inputs (the x value) repeat it's not a function

Answer:

We need to find the number of shirts he sold using: 15s - 100 = 350

s = 30

So, Rory sold 30 shirts :)

The required expression that defines the scenario is 15s - 100 = 350 and the number of t-shirts sold is 30. Option D is correct.

Given that,
Rory sold T-shirts at a festival for $15 each. He paid $100 in materials and fees. Rory's profit after the festival was $350. He wants to know how many shirts he sold.

According to the assertions, it deals with a number of operations in mathematics. Addition, subtraction, multiplication, and division are the four main arithmetic operators.

Here,
Let the number of the t-shirts be s,
According to the question,
Total cost of s t-shirts = 15s
He spends $100 on materials,
Profit = 15s - 100
15s - 100 = 350

Thus, the required expression that defines the scenario is 15s - 100 = 350 and the number of t-shirts sold is 30. Option D is correct.

That repeated x value is x = 0 due to the two points (0,3) and (0,0) being part of the same function. The input x = 0 maps to more than one output y = 3 and y = 0 at the same time. A function is only possible if any input x leads to exactly one output y. This is only if that x value is in the domain.

Visually, plotting (0,3) and (0,0) together shows that this graph does not pass the vertical line test. It is possible to draw a vertical line through more than one point on this graph. So this is a quick visual way to see that we don't have a function.

An ordered pair may or may not represent a function.

The true statement is (d) No, because an x-value is repeated

The ordered pairs are given as:

[tex]\mathbf{(x,y) = (0, 3), (3, 2), (2, 1), (0, 0)}[/tex]

For an ordered pair to be a function, no x-value must be repeated for different y-values.

From the given ordered pair, 0 is repeated for y-values 3 and 0.

This means that, the ordered pair is not a function.

Hence, the true statement is (d)

Answer:

Not a function

Step-by-step explanation:

If it is a function, every input has only one output. Meaning if we graph it, it will pass the vertical line test.

If you want to think about it in x and y, all values of x can only correspond to one value of y.

In this case, we can see that the x-value 6 has 2 corresponding y-values (5 and 10), therefore, this mapping is not a function.
