Answer:
A.) = 40° B.) = 90° C.) = 53.5° D.) = 34° E.) = 90° F.) = 52.9° G.) = 90°
H.) = 59.6° I.) = 119.1° J.) = 30.4° K.) = 90° L.) = 72° M.) = 107.3°
N.) = 47.7° O.) = 36° P.) = 90°
Step-by-step explanation:
All triangles are 180°
So:
A.) 72 + 68 = 140 180 - 140 = 40
The little boxes in the triangle indicates that the angle is a right angle. Right angles are 90°
B.) Is a right angle
C.) 36.5 + 90 = 126.5 180 - 126.5 = 53.5
D.) 56 + 90 = 146 180 - 146 = 34
E.) Is a right angle
F.) 95 + 32.1 = 127.1 180 - 127.1 = 52.9
G.) Is a right angle
H.) 30.4 + 90 = 120.4 180 - 120.4 = 59.6
To find angle I you have to find angle J first. So, because there is a box. That indicates that both angle equal 90°.
So you have to subtract H from 90° H = 59.6
J.) 59.6 - 90 = 30.4
I.) 30.5 + 30.4 = 60.9 180 - 60.9 = 119.1
K.) 45 + 45 = 90 180 - 90 = 90
L.) 33 + 75 = 108 180 - 108 = 72
M.) 37 + 35.7 = 72.7 180 - 72.7 = 107.3
N.) 92.3 + 40 = 132.3 180 - 132.3 = 47.7
O.) 54 + 90 = 144 180 - 144 = 36
P.) Is a right angle
Hope this helps : )
The missing angles are
A = 40°, B = 90°
C = 53.5°, D = 34°
E = 90°, F = 52.9°
G = 90°, H = 59.6°
I = 119.1°, J = 30.4 °
K = 90°, L = 72°
M = 107.3°, N = 47.7°
O = 36°, P = 90°
Sum of angles in a triangleThe Sum of angles in a triangle is 180 degrees. Therefore,
A = 180 - 72 - 68 = 40 degrees(sum of angles in a triangle)
B = 90 degrees(right angle)
C = 180 - 90 - 36.5 = 53.5 degrees(sum of angles in a triangle)
D = 180 - 90 - 56 = 34 degrees(sum of angles in a triangle)
E = 90 degrees(right angle)
F = 180 - 95 - 32.1 = 52.9 degrees(sum of angles in a triangle)
G = 90 degrees(right angle)
H = 180 - 90 - 30.4 = 59.6 degrees(sum of angles in a triangle)
I = 180 - 30.4 - 30.5 = 119.1 degrees(sum of angles in a triangle)
J =90 - 59.6 = 30.4 degrees
K = 180 - 45 - 45 = 90 degrees(sum of angles in a triangle)
L = 180 - 75 - 33 = 72 degrees(sum of angles in a triangle)
M = 180 - 35.7 - 37 = 107.3 degrees(sum of angles in a triangle)
N = 180 - 40 - 92.3= 47.7 degrees(sum of angles in a triangle)

It'll be at
96

and
seconds
Answers
Answer:
t=6
Step-by-step explanation:
We are solving for [tex]t[/tex]. To do this, let's fill in the known variables.
[tex]h=vt-16t^2[/tex]
[tex]v=80\\h=96[/tex]
[tex]96=80t-16t^2[/tex]
[tex]16t^2-80t+96=0\\16(t^2-5t+6)=0[/tex]
Since the product must equal 0, that means that the factor in the parentheses hasto be equal to 0. Therefore,
[tex]t^2-5t+6=0\\(t+1)(t-6)=0\\\\t+1=0 OR t-6=0\\t=-1 OR t=6[/tex]
However, since the time cannot be negative, [tex]t=-1[/tex] cannot be a valid answer.
Therefore, the only valid time is t=6.
I hope this helps.
Let's start with the projectile motion formula which is h = vt - 16t².
In this formula, h is the height of the object,
v is the initial velocity, and t is the time.
We know that the initial velocity is 80 feet per second
so we can plug an 80 in for v in our formula.
We also know that the object reaches a height of 96 feet above the
ground which means we can plug an 96 in for h in our formula.
So we have 96 = 88t - 16t².
To solve this equation, we set it equal to 0 by subtracting
88t and adding 16t² to get 16t² - 88t + 96 = 0².
Now we can divide both sides by 8 to get 2t² - 11t + 12 = 0.
Now we can factor the left side to get (2t - 3)(t - 4) = 0.
So this means that 2t - 3 = 0 or t - 4 = 0.
So t = 3/2 or t = 4.
Now, the reason there are two answer is because the object will be
96 feet off the ground on its way up and on its way down.

Which of the following expressions is equivalent to 4,325,000,000
Answers
For this case we must find an expression equivalent to:
[tex]4,325,000,000[/tex]
To express in scientific notation we must take into account that the power will be positive, that is, the decimal is run to the right.
We test each option.
Option A:
[tex]4,325 * 10^{-9}[/tex]
If we run the decimal 9 spaces to the left we have:
[tex]0.000000004325[/tex]
Option B:
We discard it because the exponent is negative.
Option C:
[tex]4,325 * 10 ^ 6[/tex]
We run the decimal 6 spaces to the right
[tex]4,325,000[/tex]
Option D:
[tex]4,325 * 10 ^ 9[/tex]
We run the decimal 9 spaces to the right
[tex]4,325,000,000[/tex]
Answer:
Option D
Final answer:
The expression that is equivalent to 4,325,000,000 is 4.325 × 10^9.
Explanation:
The expression that is equivalent to 4,325,000,000 is 4.325 × 109.
When we write a number in scientific notation, we express it as a product of a coefficient and a power of 10. In this case, the coefficient is 4.325 and the power of 10 is 9. This means that we move the decimal point 9 places to the right, resulting in a value of 4,325,000,000.
So the correct expression is 4.325 × 109.

The required line parallel to y = - 7x - 2 through (- 4, 6) is y = -7x - 22.
What is slope?The slope is the rate of change of the y-axis with respect to the x-axis.
The equation of a line in slope-intercept form is y = mx + b, where
slope = m and y-intercept = b.
We know the greater the absolute value of a slope is the more steeper is it's graph or rate of change is large.
We know parallel lines have the same slope.
Given line is y = - 7x - 2, hence the required line will also have a slope of - 7
which is passing through the point (-4, 6).
∴ 6 = (-7)(-4) + b.
6 = 28 + b.
b = - 22.
Hence the required line is y = -7x - 22.

Final answer:
To simplify an algebraic equation, combine like terms, reduce fractions, and cancel factors; multiply or divide both sides by the same number if needed, and check your work by substituting values back into the original equation.
Explanation:
Simplifying Algebraic Equations
To simplify an algebraic equation, you need to eliminate terms wherever possible. This process may involve combining like terms, reducing fractions, and canceling out factors. Multiplication or division by the same number on both sides of the equation does not change the equation's equality, so apply these operations carefully to all terms. Often, you'll want to collect constants inside the parentheses to consolidate them into a single value, making the equation simpler. After simplifying, it's important to check your answer to ensure that it is reasonable, which may involve plugging the solution back into the original equation or assessing the steps you've taken to make sure no errors were made.
Let's consider an example:
Simplify the equation by dividing both sides by a common factor, if applicable.
Collect like terms together and simplify further.
Check the simplified equation by substituting numbers to see if both sides remain equal or by ensuring logical algebraic steps were taken.
Remember, solving for an unknown variable requires doing the same operation on both sides of the equation, thereby maintaining balance. Systematic simplification and attentive checking are your keys to mastering algebraic equations.

Nine increased by the product of a number and 8 is greater than -24
Answers
Answer:
x>-33/8
Step-by-step explanation:
9+8x>-24
1) Subtract 9 from both sides:
8x>-33
2) Divide both sides by 8:
x>-33/8
The algebraic representation of the problem is 9 + 8x > -24. After isolating 'x', the solution to the inequality is x > -4.125, which means any number greater than -4.125 satisfies the equation.
Explanation:The problem presented is a linear inequality, a topic of mathematics. The sentence 'Nine increased by the product of a number and 8 is greater than -24' can be represented algebraically as 9+8x > -24, where 'x' is the number in question.
To solve it, as we aim to find the value for 'x', you first isolate 'x' on one side of the inequality. Start by subtracting 9 from both sides to get 8x > -24 - 9, which results in 8x > -33. Then, you divide both sides by 8 to solve for 'x'. As a result, x > -33/8, or x > -4.125.
This means that any number greater than -4.125 will satisfy the equation 'Nine increased by the product of a number and 8 is greater than -24'. So, the solution to this inequality is x > -4.125.

The height of a triangle is twice it's base. If the area of the triangle is 40 cm squared, what is the measure of it's height
Answers
40 = x(2x)/2
80 = 2x²
40 = x²
x = sqrt40
x = +/- 2sqrt10
Measurement cannot be negative therefore x = 2sqrt10
Height = 2x = 2(2sqrt10) = 4sqrt10
The height of the triangle is 4sqrt10 cm or approximately 12.65cm.
