Given: angle 1 and angle 2 are complementary , angle 2 = 74 degrees Prove: angle 2 = 16 degrees
Answer:
I'm guessing the angle 1 is supposed to be 74 degrees and not angle 2?
Step-by-step explanation:
Either way. Complementary angles always have a sum of 90°. 74+16=90 so it checks out

Find each function value f(3) if f(x) = 2x + 2
Answer: The function value is 8.
Step-by-step explanation: Substitute 3 for x.
f(3) = 2(3) +2f(3) = 6 +2f(3) = 8Answer:
Step-by-step explanation:
okay soooo first you must multiply 3 by 2 because 3 is the element of the function (x)
your answer should be 6
now add 2 to your answer (6) and you should get 8
If the measure of two sides of the triangle are 3 feet's and 7 feet's, which is the least possible whole number measure for the third side
Answer:
5 feet
Step-by-step explanation:
By triangle inequality, the sum of lengths of any two sides has to be strictly greater than the length of the third side.
Let x feet be the length of the third side.
We have 3+x>7, x+7>3 and 3+7>x.
Solving these, we get x > 4, x > -4 and x < 10.
The solution is therefore 4 < x < 10 and the smallest whole number which satisfies the inequality is 5.
Therefore the answer is 5 feet.

Tank B, which initially contained 80 liters of water, is being drained at a rate of 2.5 liters per minute. How many liters of water remain in the tank after 30 seconds?
Answer:
78.75 ?
Step-by-step explanation:
calculator..
The volume of water remain in the tank after 30 seconds is 78.75 liters.
The given parameters;
initial volume of water in Tank B, V₀ = 80 litersrate at which water is being drained, R = 2.5 liters per minute.time of water drain, t = 30 secondsThe amount of water drained after 30 seconds is calculated as follows;
[tex]V_1 =2.5 \ \frac{liters}{\min} \times \frac{1 \min}{60 \ s} \times 30 \ s\\\\V_1 = 1.25 \ liters[/tex]
The volume of water remain in the tank after 30 seconds is calculated as follows;
V₂ = V₀ - V₁
V₂ = 80 liters - 1.25 liters
V₂ = 78.75 liters
Thus, the volume of water remain in the tank after 30 seconds is 78.75 liters.

PLZ I NEED HELP!!A tree is 12 feet tall and casts a shadow 9 feet long. A building nearby casts a shadow that measures 24 feet. How tall is the building?
A. 24
B. 21
C. 27
D. 32
Answer:
D. 32 feet
Step-by-step explanation:
A tree is 12 feet tall and casts a 9-foot shadow.
The shadow is 3/4 the length of the tree (9/12 = 3/4).
We know the shadow of a nearby building is 24 feet long.
That would be 3/4 of the height of the building.
So, fidn the reciprocal of 3/4 (4/3) and multiply by 24.
24/1 * 4/3
Cross-cancellation
8/1 * 4/1
8 * 4
The building is 32 feet tall, which is D.
Kinda confused. Will give 20pts.
Answer:
Step-by-step explanation:
the ratio between similar triangles are constant.
so 11/14 has to be equal to z/8 and also a15 = 11/14
so from this we can conclude that z = 8*14/11 = 10.18
Answer:
z = 11 and a = 12
Step-by-step explanation:
These two triangles are similar, in this case, the same angles but different sizes. The answer to this problem is the length of the sides of the triangles. You are given the right side's length on both triangles. The first triangle's sides are 3 (inches, cm, whatever form of measurement is being used) bigger than the second triangle's. Using this information, you can figure out the quantity of both a and z.
Hope this helps.

Esther and her 6 brothers went shopping at the mall. She shopped in 12 different stores while her brothers each shopped in 8 different stores. How many stores did Esther and her brothers shop in altogether?
Answer:
60 stores
Step-by-step explanation:
Here, we want to get the total number of stores in which Esther and her 6 brothers went shopping
From the question, she shopped in 12 different stores
Each of her six brothers shopped in 8 different stores
That makes the number of stores in which the brothers shop be 8 * 6 = 48 stores
The total number of stores is thus, 48 + 12 = 60 stores

Answer:
x < -5
Step-by-step explanation:
The function is increasing where its slope is positive. That is where each point is higher than the one to its left. You see that is the case for all points to the left of the vertex, which is at x=-5.
The domain where the function is increasing is x < -5.
_____
Additional comment
At the vertex, the function is horizontal, neither increasing nor decreasing. So, the vertex itself is not included in the domains of increase or decrease.

[tex]2 { }^{2} + 2 \times {2}^{2} [/tex]
Answer:
1. 2268.
2. 12.
Step-by-step explanation:
1. Given the mathematical expression; 2 * 2 * 9 * 7 * 9
We would simplify the expression;
2 * 2 * 9 * 7 * 9 = 4 * 81 * 7
2 * 2 * 9 * 7 * 9 = 28 * 81
2 * 2 * 9 * 7 * 9 = 2268
2. Given the mathematical expression; 2² + 2 * 2²
From BODMAS (Bracket Of Division Multiplication Addition Substraction), we would first of all multiply before performing an addition operation.
Therefore,
2² + 2 * 2² = 4 + 2 * 4
2² + 2 * 2² = 4 + 8
2² + 2 * 2² = 12
Answer:
1. 2268 2. 12

Answer: 464
Step-by-step explanation:
Zara has forgotten her 4-digit PIN code.
She knows the first digit is a factor of 10 and the 4 digits make a number divisible by 5.
How many different sets of 4 digits could it be?
Answer:
800 different 4 digit passwords can be the pin
Step-by-step explanation:
Since the first digit is a factor of 20, the factors of 20 are 1,2,4,5,10,20. We only need the single digit factors which are 1,2,4 and 5.
These 4 numbers can be permuted in 1 way for the first digit, so we have ⁴P₁.
For the second digit, we have 10 digits permuted in 1 way, ¹⁰P₁ and also for the third digit, we have
10 digits permuted in 1 way, and for the last digit, which is divisible by 5, it is either a 0 or 5, so we have two digits permuted in 1 way,
So, the number of different 4 digit number that Zara'2 4-digit PIN code could be is
4 × 10 × 10 × 2 = 800 different sets of digits
Please help me i struggle lots on this topic
Answer:
slope = 0
Step-by-step explanation:
remember slope is just rise (change in y) over run (change in x) and since there's no change it has a zero slope, which applies to any horizontal line parallel to the x axis
(this is just me trying to explain slopes, separate from the question you put) if the right most point was 1 higher (5,7) instead of (5,6) then the slope would be 1/2 because to get from (5,7) to (3,6) you move up 1 and over 2
