A building casts a 33 m shadow when the Sun is at an angle of 26. to the vertical. How tall is the building, to the nearest meter? Use a trigonometric ratio to find the distance F E.
Answers
so basically we just us do this
tan(26)=33/FE
Multiply to get rid of fraction
tan(26)FE=33
divide to get FE alone
FE = tan(26) * 33
FE=16.0951m
so it should be 16.0951m

Pete is having a cup of black coffee with breakfast. The glass weighs 100g and holds 100mL, so he says that the drink (the cup and coffee together) weighs 200g. Explain why Pete is mistaken
Answers
Answer:
The units g and mL measure different quantities.
Step-by-step explanation:
Pete knows the glass weighs 100g, so this is the weight of the cup.
It holds 100 mL, however, mL measures volume, not weight.
Pete is wrong about saying that the cup and coffee together weigh 200 g, because you cannot add two values together that have different units.
In this example, you cannot add together the weight of the cup and volume of the coffee, in order to get the total weight. You would have to find the weight of the coffee, then add that to the cup's weight.
So, Pete is wrong because you cannot add 2 values together that have different units.
Different quantities are measured by the units g and mL.
What is unit conversion?Multiplication or division by a numerical factor, selection of the correct number of significant figures, and unit conversion are all steps in a multi-step procedure.
Pete knows the glass weighs 100g, so this is the weight of the cup. It holds 100 mL, however, mL measures volume, not weight. Pete is mistaken when he claims that the coffee and cup combined weigh 200 g since you cannot add two values with different units of measurement.
In this case, you cannot calculate the entire weight by adding the weight of the cup and the volume of the coffee. You would need to determine the weight of the coffee and then increase it by the weight of the cup.
Therefore, Pete is wrong because you cannot add 2 values together that have different units.

Name the additive inverse of 5 + I
Answers
Answer:
so
Step-by-step explanation:
For example, the additive inverse of the positive number 5 is -5. ... This means that the additive inverse of a negative number is positive. For instance, if x equals -12, then its additive inverse is y = 12.
The additive inverse is (-5) + (-1)
what is additive Inverse?To get a result equal to 0, add the original number and the additive inverse by simply changing the sign of the integer. On the basis of negation of the original number, the characteristics of additive inverse are listed below. For instance, if x is the starting number, then -x is x's additive inverse.
Given:
5 + I
As, the additive inverse is the opposite sign of the given number.
For example, if the number is -6 and we have to find its additive inverse.
So, the additive inverse will be 6.
So, the additive inverse is (-5) + (-1)

Answers
Answer:
h = 10 + 8y
Step-by-step explanation:
Given that :
Height of ght if all alien at birth = 10cm
Growth rate per year = 8 cm
Let:
y = number of years since birth
h = alien's height in centimeter
Relationship between h and y
h = Initial height + (growth rate per year*number of years)
h = 10 + 8y

The solution for the scientific notation will be 3.6 x 10⁻¹¹.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that the scientific notation is calculated as below,
E = (4x 10⁻⁵) (9x 10⁻⁵)
E = ( 4 x 9 ) ( 10⁻⁵ x 10⁻⁵ )
E = 36 x ( 10⁻¹⁰)
E = 3.6 x 10⁻¹¹
Therefore, the solution for the expression will be E = 3.6 x 10⁻¹¹.

Triangle ABC is similar to triangle XZY. Find the missing side x using proportions ( PLEASEE HELP ASAP)
Answers
Answer:
x=70º
Step-by-step explanation:
Triangle ABC, A/C=50º, B/C=40º
40º+50º=90º
Triangle XZY, Y/Z=20, Y/X=x
Since it is a right triangle it will add up to 90º.
So 90º-20=70
The missing angle x is 70
x= 70
The length of the unknown side of the triangle XYZ is 25 units.
What is similarity of triangles?
Two figures are similar if their corresponding angles are congruent , and the ratios of the lengths of their corresponding sides are equal. This common ratio is called the scale factor.
Given is Triangle ABC which is similar to triangle XZY.
Since both the triangles are congruent to each other, their corresponding sides will be in equivalent ratios. Therefore, we can write-
BC/YZ = AC/YX
40/20 = 50/x
x = (50 x 20)/40
x = 50/2
x = 25
Therefore, the length of the unknown side of the triangle XYZ is 25 units.
