Question 27 Mike is remodeling his kitchen. The countertop he wants costs $2.80 per square foot. How much will Mike have to spend on his remodeling project
Answers
Answer: $67.20
Step-by-step explanation: i got it right
Mike has to spend $67.20 on his remodeling project.
Explanation:
6 ft = (4 + x) ft
4+x = 6
x = 6-4 = 2
Area 1:
S1 = 2 × (4+2)
= 2 × 6
= 12 ft²
Area 2:
S2 = 2 × (4+2)
= 2 × 6
= 12 ft²
The area of his kitchen is S1 + S2 = 12 + 12 = 24ft²
= 24 × 2.80
= $67.20
The image is given below for the area of the house.

Answers
The measure of ∠A is 115˚.
Given that, ∠A and ∠B are supplementary angles. ∠A=(7x + 24)˚ and ∠B=(7x − 26)°.
What are supplementary angles?Two angles are Supplementary when they add up to 180 degrees.
Now, ∠A+∠B=180°
⇒(7x + 24)˚+(7x − 26)°=180°
⇒14x− 2°=180°
⇒14x=182°
⇒14x=182°
⇒x=13°
Now, ∠A=7×13 + 24˚
⇒∠A=91˚+ 24˚=115˚
Therefore, the measure of ∠A is 115˚.

Answer:
There are 4 red counters
Step-by-step explanation:
1. Add the known decimals
[tex]0.25+0.35+0.3=0.9[/tex]
2. Subtract that amount from one
[tex]1-0.9=0.1[/tex]
3. multiply the result by 40
[tex](40)(0.1)=4[/tex]
Hope this helps
Step-by-step explanation:
a probability is always desired cases / total cases.
from the table and given information we know :
there are 40 blue counters.
0.25 = 40/x
x being the total number of counters in the box.
x = 40 / 0.25 = 160
the sum of all probabilities must be 1 (the always true probability), as there are only counters in the box, and one of the 4 colors is always the result.
so,
1 = 0.25 + 0.35 + 0.3 + red-probability
1 = 0.9 + red-probability
red-probability = 1 - 0.9 = 0.1
0.1 = red counters / 160
red counters = 0.1 × 160 = 16
there are 16 red counters in the box.

in poker, a royal flush is a hand with the ace, king, queen, jack and 10 of all one suit and is the best possible hand in the game. what is the probablity of a royal flush in a 5 card hand
Answers
The probability of a royal flush in a 5-card hand is 1/649740 or 0.0001539%.
The combination is a way of selecting a smaller number of sets from a larger number of sets in no particular order.
If selecting r items from a set of n items, in no particular order, we use combinations, using the formula:
nCr = n!/{r!(n - r)!}.
In the question, we are asked the probability of a royal flush in a 5 card hand.
The number of ways of selecting 5 cards from a deck can be computed using a combination, 52C5, as we have 52 cards in a deck, 5 cards are to be chosen and the order is not in concern.
52C5 = 52!/{5!(52 - 5)!} = 52!/(5!.47!) = (52*51*50*49*48)/(5*4*3*2*1) = 2598960.
The number of hands that make a royal flush is only 4. 4 from each suit.
Therefore, the probability = 4/2598960 = 1/649740 or 0.0001539%.
Therefore, the probability of a royal flush in a 5-card hand is 1/649740 or 0.0001539%.

Answers
The he statement d(k) + (k + 1) = d(k+1) is true for all natural numbers, n, by mathematical induction.
To prove that the statement is true for all natural numbers, n, we can use mathematical induction.
The statement we want to prove is that d(k) + (k + 1) = d(k + 1), where d(n) represents the total number of dots in a pattern of n squares.
Base Case (n = 1):
First, let's prove the statement for the base case, n = 1.
For n = 1:
d(1) + (1 + 1) = d(1) + 2
Now, consider a single square with 1 dot.
In this case, d(1) = 1.
So, we have:
1 + 2 = 3
Now, let's consider a pattern of 2 squares (n = 2).
The first square has 1 dot, and the second square has 2 dots. So, d(2) = 1 + 2 = 3.
So, the statement is true for n = 1.
Inductive Hypothesis (Assume true for n = k):
Now, assume that the statement is true for some arbitrary natural number k.
That is, assume that: d(k) + (k + 1) = d(k + 1)
Inductive Step (Prove true for n = k + 1):
To prove that the statement is true for n = k + 1.
d(k + 1) + (k + 2) = d(k + 2)
Now, consider a pattern of (k + 1) squares.
By the inductive hypothesis, assume that the statement is true for k squares:
d(k) + (k + 1) = d(k + 1)
Now, let's add one more square to the pattern.
This square will have (k + 2) dots.
So, the total number of dots in the pattern of (k + 1) squares plus the (k + 2) dots in the additional square is:
d(k + 1) + (k + 2)
And by the inductive hypothesis, d(k) + (k + 1) = d(k + 1).
Therefore:
d(k + 1) + (k + 2) = (d(k) + (k + 1)) + (k + 2) = d(k) + (k + 1) + (k + 2)
Now, simplify:
d(k + 1) + (k + 2) = d(k + 1) + (k + 1 + 1)
So, it is shown that for n = k + 1, d(k + 1) + (k + 2) = d(k + 1) + (k + 1) + 1.
Since it is assumed the statement to be true for k and proved it for k + 1, it is shown that the statement is true for all natural numbers, n, by mathematical induction.

- since these are right triangles you can use trigonometry to solve this pretty easily
- for this situation, you only have to use sine/sin
sine/sin is [tex]opposite/hypotenuse[/tex]__________________________________________________________
- to start you just need to identify which side is which:
the side that is labeled 10 is the hypotenusein this case, the shared side is the opposite since you're using sin- so, for this problem the equation is: [tex]10xSin(45) = 7.071067812[/tex]
__________________________________________________________
- so 7.071067812 is the hypotenuse of the smaller triangle so you just do the same thing again
- start with identifying which side is which:
as said, the side that is shared and 7.071067812 is the hypotenusethe side labeled x is the opposite- so for this part, the equation is: [tex]7.071067812xSin(45) = 5.0[/tex]
