Answer:
B)blocks in 5th row=15+(5-1)(-2)
Step-by-step explanation:
We are given that
Number of block in bottom row=15
Each row has 2 fewer blocks than the previous row
We have to find the formula would you use to find the number of blocks in the 5th row.
Number of blocks in second row=15-2=[tex]15+1(-2)[/tex]
Number of blocks in third row=15-2-2=[tex]15+2(-2)[/tex]
Number of blocks in 4th row=[tex]15-2-2-2=15+3(-2)[/tex]
Number of blocks in 5th row=[tex]15-2-2-2-2=15+4(-2)[/tex]
Therefore, number of block in 5th row
[tex]15+(5-1)(-2)[/tex]
This is required formula to find the number of blocks in the 5th row
Hence, option B is true.
B)blocks in 5th row=15+(5-1)(-2)

A letter from the word CONFIDENCE is chosen at random, then a card is drawn from a standard deck. What is the probability of getting a consonant, them a red card or ace.
Answer:
9/26
Step-by-step explanation:
Word : CONFIDENCE
Consonants in word : C, N, F, D, N, C = 6
Total alphabets = 10
Probability =required outcome /Total possible outcomes
Probability (consonants) = 6 /10 = 3/5
Number of red catds in deck = 26
Number of aces in a card deck = 4
Total number of cards = 52
P(red) or P(ace)
(4/52) + (26/52) = (4 + 26) / 52 = 30 / 52 = 15 / 26
P(getting a consonant, then a red card or ace)
(3 /5) * (15/26) = (3 * 15) / (26 *5) = 45/130 = 9/26

Step-by-step explanation:
A ceramic vase that cost an antique store $7 was marked $63. What is the percentage markup on the price of the ceramic vase?
A-56%
B-900%
C-800%
D-44%
9514 1404 393
Answer:
C) 800%
Step-by-step explanation:
The markup amount is the difference between the selling price and the cost:
markup = selling price - cost
markup = $63 -7 = $56
The percentage markup relative to the cost is ...
markup/cost × 100%
= ($56)/($7) × 100%
= 8×100% = 800%
The graph shown below represents a ladder leaning against wall the bottom of the latter is 4 feet from the wall in the top of the ladder reach is 20 feet above the ground what is the slope of graph (I’m so sorry I don’t have a picture)
Answer:
C.) -5
Step-by-step explanation:
The slope formula is rise/run, in other words, rise divided by run or the y variable divided by the corresponding x variable.
In this question, we are told that the y-value is "20 feet above" meaning this is the rise and the run is "4 feet from"
To find the slope all we have to do is divide 20 by 4 giving us 5. Since the ladder is going down we know that we have to place a negative sign before the slope giving us our final answer of -5
If JK = 8x + 24 and NO = 20, what is the value of x?
Answer:
x=2
Step-by-step explanation:
So..
NO=1/2 of JK because the two segments are parallel
Therefore because you have NO plug that into..
NO=1/2JK
YOU GET
1/2JK=20 multiply 2 so you can isolate JK
JK=40
Then plug that back into your JK=8x+24
40=8x+24 next subtract 24 on both sides
8x=16
x=2

What is the solution to the equation x÷8−6=3?
A. x=1
B. x=24
C. x=48
D. x=72
30 POINTS TO THE RIGHT ANSWER AND BEST EXPLANTION.
Answer: D. x=72
Step-by-step explanation:
With the equation x/8-6=3 we can start solving by first moving the "-6"
x/8-6(+6)=3(+6)
x/8=9 <-- Rewrite equation after adding "6" to both sides
x/8(*8)=9(*8) <--- Multiply both sides by 8
x=72 <-- After multiplying, solution is found

Is this the answer to this question i need help
Answer:
No, A is
Step-by-step explanation:
You can tell by plugging in the numbers. 0 - 3(0) < 1 as 0 < 1.
============================================================
Explanation:
Let's check if choice C is the answer or not
We will plug in x = -2 and y = 1 into the inequality to get
y - 3x < 1
1 - 3(-2) < 1
1 + 6 < 1
7 < 1
That's a false statement since 7 is not smaller than 1. This means the first inequality is false when (x,y) = (-2,1). So we can rule out choice C. Choices B and D are similar stories.
---------------
It turns out that choice A is the answer because
y - 3x < 1
0 - 3(0) < 1
0 - 0 < 1
0 < 1
Which is a true statement. So (x,y) = (0,0) is one solution to this inequality.
I'll let you check the other answer choices. You should find them to be false
