2ii answer is 8
2iii answer is -1
2iv ans is 9
Step-by-step explanation:
X + 2 =7
X = 7 - 2
X = 5
3x - 1 = 23
3x = 23 + 1
3x = 24
X = 8
5x + 7 = 2(X+2)
5x + 7 = 2x + 4
5x - 2x = 4 -7
3x = -3
X = -1
5x - 1 = 44
5x = 44+1
5x = 45
X = 9

alice is making a necklace she has a chain that is 400 mm long she puts forty 1.7 mm beads twenty-seven 6.5 mm beads and eight 3.4 mm beads on the chain about how much of the 400 mm chain is left withoutbeads?
388 mm
270 mm
230 mm
129 mm
Answers
Answer: I believe its D
The 129 mm length is left out of the 400 mm total length of the chain if she puts forty 1.7 mm beads twenty-seven 6.5 mm beads and eight 3.4 mm beads on the chain option (D) is correct.
What is an arithmetic operation?Arithmetic is an area of mathematics involving the study of numbers and the different operations that can be performed on them. Addition, subtraction, multiplication, and division are the four basic math operations.
We have:
The total length of the necklace chain = 400 mm
Alice put 40 Nos 1.7 mm beads
Length for this = 40×1.7 = 68 mm
Alice put 27 Nos 6.5 mm beads
Length for this = 27×6.5 = 175.5 mm
Alice put 8 Nos 3.4 mm beads
Length for this = 8×3.4 = 27.2 mm
Total length occupied = 68+175.5+27.2 = 270.7 mm
The length of 400 mm chain is left = 400 - 270.7 = 129.3 ≈ 129 mm
Thus, the 129 mm length is left out of the 400 mm total length of the chain if she puts forty 1.7 mm beads twenty-seven 6.5 mm beads and eight 3.4 mm beads on the chain.

Si una escalera de bomberos de 37 metros de longitud,se apoya en la pared de un edificio,poniendo el pie de la escalera a 12 metros del edificio, ¿que altura, en metros, alcazan la escalera?
Answers
Answer:
La escalera alcanza 35 metros de altura.
Step-by-step explanation:
La altura que alcanza la escalera se puede calcular usando Pitágoras:
[tex] L^{2} = B^{2} + A^{2} [/tex]
En donde:
L: es la longitud de la escalera = 37 m
B: es la distancia del pie de la escalera al edificio = 12 m
A: es la altura =?
Entonces, la altura es:
[tex] A = \sqrt{L^{2} - B^{2}} = \sqrt{(37 m)^{2} - (12 m)^{2}} = 35 m [/tex]
Por lo tanto, la escalera alcanza 35 metros de altura.

Joe is interested in the prices of homes sold in his area. He found a list of the selling prices of 50 homes for the past month. Most of the homes sold for $100,000-$350,000, but there were a few that sold for more than $1,000,000. Which of the following statements is true about the mean and median selling price for the 50 homes?
The mean and median are equal.
O The mean is less than the median.
O The mean is greater than the median. O The actual selling prices are needed to determine this.
Answers
Using the concepts of mean and median, it is found that the correct option is given by:
The mean is greater than the median.
-----------------
The mean of a data-set is given by the sum of all it's values divided by the number of values.The median is the 50th percentile, that is, the measure which is lower than other 50% of the measures and also higher than other 50%.As the mean includes all values, it is affected by outliers.-----------------
Most of the homes sold for $100,000-$350,000, which means that both the mean and the median should be values in this interval.The few that sold for more than $1,000,000 are outlier values, which will affect the mean.Since these values are greater than the usual values(between $100,000 and $350,000), these values will increase the mean, meaning it will be greater than the median, and the correct option is given by:The mean is greater than the median.
A similar problem is given at https://brainly.com/question/20988403
Answer: C. The mean is greater than the median
Step-by-step explanation:
Without knowing the actual selling prices of the homes, it's difficult to determine the relationship between the mean and median. However, it is possible that a few extremely high selling prices could significantly increase the mean but not have much effect on the median. Therefore, it's possible that the mean is greater than the median.

sales tax is added.
What is the total after discount and tax?
Answers
