this is a true or false thing for geometry

Answers

1) False
2) If two angles are 45 degrees then they are complementary and congruent.

Explanation: Complementary angles add up to 90 degrees and congruent angles are angles that are equal. Two 45 degree angles are equal to each other and add up to 90 degrees. The first statement is false because there are many combinations of angles that add up to 90 degrees that are not the same. (30 degrees and 60 degrees)

At noon, a tank contained 5 in. of water. After several hours, it contained 4 in. of water. What is the percent decrease of water in the tank?

Answers

The water decreased by 50% because the water started at 8 cm and went down to 4 cm. Half of 8 is 4, or if you multiply 8 by .5, or 50%, you get 4.
I’m not for sure if this is correct, if it’s wrong I am very sorry!! I hope you have a great day :).

Answer:

20%

Step-by-step explanation:

4 is 80% of 5, so all we need to do is find out what percent is left after 80%, 20%, and then that would be how much it decreased

24-10b=9 what is the missing variable equal to

Answers

Answer:

b = 1.5

Step-by-step explanation:

Lets first set up the equation:

24 - 10b = 9

Okay now lets add 10b on both sides:

24 = 9 + 10b

Now let's subtract 9 from both sides so we can get the variable b by its self:

15 = 10b

Okay now we can divide each side by 10:

1.5 = b

Answer:

24-10(1.5)=9

b = 1.5

Step-by-step explanation:

Isolate the variable by dividing each side by factors that don't contain the variable.

Exact Form:

b  =  3 /2

Decimal Form:

b =  1.5

10(1.5) = 15

24 - 15 = 9

Twinkle toes tony kick the football and it landed 100 feet from where he kicked it also reach a maximum height of 125 feet write an equation that models the path of the ball while it was in the air

Answers

Answer:

The equation that models the path of the ball is y = 5·x - 0.05·x²

Step-by-step explanation:

The given information are;

The distance the football landed from where it was kicked = 100 feet

The maximum height the football reached =  125 feet

The equation that models the path of the ball is that of the equation of parabola in vertex form, given as follows;

y = a·(x - h)² + k

Where;

(h, k) = The coordinate of the vertex (which is the coordinates of the highest point reached by the ball)

Therefore, taking the x-coordinate of the highest point reached by the ball as midpoint of the horizontal distance moved by the ball, we have;

The x-coordinate of the midpoint of the horizontal distance moved by the ball = (50, 0)

We have;

The coordinate of the highest point reached by the ball = (50, 125)

Therefore;

(h, k) = (50, 125)

Substituting the above values in the equation of the parabola gives;

y = a·(x - 50)² + 125

At x = 100, y = 0, which gives;

0 = a·(100 - 50)² + 125 = a·2500 + 125

0 = a·2500 + 125

a = -125/2500 = -0.05

Therefore, we have;

y = a·(x - h)² + k = y = -0.05 × (x - 50)² + 125 = -0.05·x² + 5·x - 125 + 125

y  = -0.05·x² + 5·x - 125 + 125 = -0.05·x² + 5·x

y =  -0.05·x² + 5·x

The equation that models the path of the ball is y =  -0.05·x² + 5·x.

Which equation describes the line parallel to y = –7x + 15 that contains P(9, –6)?

Answers

Parallel means same slope. So you have to use point slope form. (x1,y1) is (9,-6) and the slope is -7

So it would be

y-(-6)=-7(x-9)

y+6=-7x+63

Solving for y gives you

y=-7x+57

A canoe rental service charges a $20 transportation fee and $30 dollars an hour to rent a canoe. Write an equation representing the cost, y, of renting a canoe for x hours. What is the cost of renting the canoe for 6 hours?

Answers

Answer:

use slope intercept form to write the equation   y=mx+b   m (slope of the line) will be the hourly fee, and b (y-intercept) will be the one-time transportation fee.

y=30x+20

to find the cost of renting a canoe for 6 hours, plug 6 into the equation replacing x

y=(30×6)+20

y=180+20=$200

Executive office of the president What is the purpose of this excerpt from the article "What Is GIS?"?GIS also can be used for complex modeling to answer a wide range of "what if" and ecosystem simulation questions. These may be cartographic models designed to document the co-occurrence or interrelationship of multiple data layers or they may be hypothetical research models designed to mimic natural ecological systems. Similarly, modeling with GIS can be used to predict the impacts that one set of parameters will have on another. For example, wetlands, soils, hydrography, climatology and elevation data can be combined to model flooding within a river system. Upstream changes in land use within the same system can be modeled to determine the potential impact of conversion of a forested floodplain to residential development or to agriculture. As a result, both natural system responses to storm events and the impact of human land use decisions can be assessed prior to the proposed action.A. to warn readers about the hazards of diminishing wetlandsB. to inform readers about the multiple uses of GISC. to explain the workings of the ecosystem simulationsD. to instruct readers about proper use of GIS resources You are a school photographer taking individual and class pictures for two classes of 21 students each on average each individual picture takes three minutes in a class picture takes 10 minutes how long should it take for you to take all the pictures Two horses galloped past the fence as if they owned the arena.a.prepositionb.conjunctionc.interjection Review Seths steps for rewriting and simplifying an expression.Seth's first mistake was made in (blank)Step 1, Step 2, Step 3, Step 4, or Step 5where he (blank)Factored 16 out of the second term instead of 4Did not apply the properties of exponents correctlyFactored 2 out of the first term instead of 4Did not write the expression as division correctly Is y directly proportional to x based on the data in the table?A) YesB) NoNEED ASAP On October 1, 2021, Chief Corporation declared and issued a 14% stock dividend.
