Step-by-step explanation:
we know that the two angles with x are equal since they are made with the same lines
so
8x+36=5x+51
solve for x
a. subtract 36 from both sides
8x=5x+15
b. subtract 5x on both sides
3x=15
c. divide by 3
x=3
now to find z
we know a line equals 180
so
(8x+36)+z=180
plug in 3
8(3)+36+z=180
24+36+z=180
60+z=180
z=120

as part of a science experiment, Carson designs and creates a cushioned egg carrier. he puts an egg inside it and then drops it from a window to see whether his design can safely cushion the egg and keep it from breaking. the egg's height in feet x seconds after being dropped is given by 27 - 16x^2. after how many seconds will the egg hit the ground?
Answer: To find out how many seconds it will take for the egg to hit the ground, we need to find the value of x when the height of the egg is 0 feet. We can do this by setting the height of the egg equal to 0 in the equation 27 - 16x^2 and solving for x.
The equation for the height of the egg in feet x seconds after being dropped is given as:
27 - 16x^2 = 0
Subtracting 27 from both sides of the equation gives us:
-16x^2 = -27
Dividing both sides of the equation by -16 gives us:
x^2 = 27/16
Taking the square root of both sides of the equation gives us:
x = sqrt(27/16)
Plugging this value into the equation for the height of the egg gives us:
27 - 16(sqrt(27/16))^2 = 0
Simplifying this equation gives us:
27 - 16(27/16) = 0
Which simplifies to:
27 - 27 = 0
This equation is true, so the value of x that we found is a solution to the equation. This means that the egg will hit the ground after sqrt(27/16) seconds.

6. x = 28 degrees
7. z = 1.6 cm
6. Notice that you can use the property that tells us that the addition of all internal angles of a triangle must give 180 degrees, then you write the following equation:
50 + 69 + (2 x +5) = 180
combine like terms:
119 + 2 x + 5 = 180
124 + 2 x = 180
subtract 124 from both sides:
2 x = 56
divide by 2 both sides:
x = 56 / 2
x = 28 degrees
Problem 7.
If the two triangles are congruent, then the side MN must equal side RS.
Since MN measure 1,8 cm, then RS must also measure 1.8 cm
and we can write the equation:
1.8 = 3 z - 3
adding 3 to both sides:
1.8 + 3 = 3 z
4.8 = 3 z
dividing both sides by 3:
z = 4.8 / 3
z = 1.6 cm

If the hypotenuse and one leg of one right-angled triangle are equal to the corresponding hypotenuse and leg of another right-angled triangle, the two triangles are congruent.
What is congruent triangle?The SSS congruence theorem tells us that the triangles are congruent because there are three pairs of congruent sides. The corresponding triangle sides are also in proportion, so they are similar according to the SSS similarity theorem.The term “congruent” means exactly equal shape and size. This shape and size should remain equal, even when we flip, turn, or rotate the shapes.If two triangles have the same size and shape they are called congruent triangles. If we flip, turn or rotate one of two congruent triangles they are still congruent. If the sides of two triangles are the same then the triangles must have the same angles and therefore must be congruent.The measurement of side DF is 4cm.If all three corresponding sides are equal and all three corresponding angles are equal in measure, two triangles are said to be congruent.Here in the figure attached below,
Given two triangles ΔABC and ΔDEF
Also given that,
ΔABC and ΔDEF are congruent to each other.

Use the formula A=P(1+r/n)ⁿt to solve the compound interest problem
Find how long it takes for $ 900 to double if it is invested at 6 % interest compounded monthly.
The money will double in value in approximately years.
It takes 11.55 years for money to double if invested at 6% compound interest.
What is compound interest?
The interest that is calculated using both the principal and the interest that has accrued during the previous period is called compound interest. It differs from simple interest in that the principal is not taken into account when determining the interest for the subsequent period with simple interest. Compound interest is commonly abbreviated C.I. in mathematics.Calculating the answer exactly: P⁰°⁰⁶ⁿ=A .
We don’t know the initial value of the principal but we do know that the accumulated value is double (twice) the principal.
P⁰°⁰⁶ⁿ = 2P
We divide both sides by P
e⁰°⁰⁶ⁿ = 2
Using natural logarithm:
0.06 n = ln(2)
n = ln(2)/0.06

(a) 794g of the initial sample will be left in the sample after 25 years. (b) Time taken to decay to half of its original amount is 3.39 years.
Isotopes(200g) are atoms that have the same number of protons in their nucleus, but a different number of neutrons. This means that they have the same atomic number, but a different atomic mass. Because of this, isotopes have different physical and chemical properties. Isotopes can be stable, meaning that they do not undergo radioactive decay, or they can be unstable, meaning that they will undergo radioactive decay over time.
(a) Substituting 25 for t in the expression, we get:
[tex]A(25) = 200e^{0.0541 \times 25}[/tex]
[tex]= 200e^{1.3525}[/tex]
Thus, after 25 years, there will be
[tex]200e^{1.3525} = 2003.97[/tex]
794 g of the initial sample left in the sample.
(b) We want to find t such that
[tex]A(t) = 200e^{0.0541}[/tex]
= 100.
Solving for t, we get:
[tex]= 200e^{0.0541} \times t=100[/tex]
Dividing both sides by 200 and applying the natural logarithm to both sides, we get:
0.0541 × t = ln(0.5)

There are many different types of hexagons. The most common type is a regular hexagon, which is a hexagon that has sides of equal length and angles of equal measure. The perimeter is the total length or distance around a two dimensional shape. In the figure below, the perimeter of each shape is the sum of the lengths of each side, shown in red. The perimeter of a circle or ellipse is called the circumference. For a polygon, the perimeter is the sum of its side lengths.
The given polygon is a regular hexagon with perimeter 120 m.
Thus, the length of each side,

⇒ 342 / 38
Apply the division operation, and we get
⇒ 9
Therefore, the required quotient is 34.2 ÷ 3.8 = 9.

Is 2 fourths greater than 2 thirds?
Answer:
NO
Step-by-step explanation:
Two fourths =
[tex] \frac{2}{4} = 0.5[/tex]
Two thirds =
[tex] \frac{2}{3} = 0.66667[/tex]
Therefore
0.66667 > 0.5
[tex] \frac{2}{3} > \frac{2}{4} [/tex]
or
0.5 < 0.66667
[tex] \frac{2}{4} < \frac{2}{3} [/tex]
i hope this helped
Answer: No, 2/4 is not greater than 2/3
Step-by-step explanation: To find an easy way to calculate their values we have 2 options. So, the 1st option is to turn them into a decimal. I already calculated their values which are:
2/4 = 0.5
2/3 = 0.667
Then, we compare the two decimal numbers to get the answer.
0.5 is not greater than 0.667.
The 2nd way is to find a common denominator, which would look like this:
2/4 = 6/12
2/3 = 8/12
8/12 is greater than 6/12, so that also proves that 2/4 is not greater than 2/3.
3. Given the function f(x) shown graphed below, what is its average rate of change from } x=1 to x=7 ?
(1) -1
(2) -4/3
(3) 8
(4) 3/5
4. A function h(x) has an average rate of change equal to 7 on the interval 5 ≤ x≤ 9. If h(5)=12, then which of the following must be the value of h(9) ?
3) The rate of change on the interval [1, 7] is -1, so the correct option is A.
4) By using the rate of change formula, we will see that h(9) = 40
How to find the average rate of change?We know that for a function f(x), the average rate of change on the interval [a, b] is:
r = ( f(b) - f(a))/(b - a)
Here the interval is [1, 7]
Using the graph we can see that:
f(1)= 6
f(7) = 0
Then the average rate of change is:
r = ( f(7) - f(1))/(7 - 1)
r = (0 - 6)/6 = -1
The correct option is A.
4) Which will be value of h(9)?
We know that the average rate of change of h(x) is 7 on the interval [5, 9]
Then we can write:
7 = ( h(9) - h(5))/(9 - 5)
We know that h(15) = 12, then we have the equation:
7 = (h(9) - 12)/4
Now we can solve that for h(9), we will get:
7 = (h(9) - 12)/4
7*4 = h(9) - 12
28 = h(9) - 12
28 + 12 = h(9)
40 = h(9)
