Answer:
360 texts
Step-by-step explanation:
Given,
The points given for 3 texts = 15,
So, the points given for 1 text = [tex]\frac{15}{3}[/tex] = 5,
If x text are sent,
Then the number of points earned = x × points for 1 text
= 5x
According to the question,
5x = 1800
[tex]\impilies x = \frac{1800}{5} = 360[/tex]
Hence, 360 texts needs to send to get 1800 points.

9/8*0.97 which is closer to a.0.5 b.1 c.2
Final answer:
After performing the multiplication 9/8*0.97, which equals 1.09125, we find that this number is closest to 1 as compared to the other options provided (0.5 and 2).
Explanation:
To determine which number 9/8x0.97 is closer to among the options 0.5, 1, and 2, we need to perform the multiplication. The fraction 9/8 can be converted to a decimal by dividing 9 by 8, which gives us 1.125. Next, we multiply 1.125 by 0.97 to find the result of the original expression.
Multiplying these two numbers gives us 1.125 x 0.97 = 1.09125. Comparing this result to the options provided, we can clearly see that 1.09125 is closest to 1.
Therefore, the answer to the question is (b) 1, since 1.09125 is very close to 1 and further away from 0.5 and 2.

Further explanation:
The distance between the two points can be calculated as follows,
[tex]\boxed{{\text{Distance}} = \sqrt {{{\left( {{x_2} - {x_1}} \right)}^2} + {{\left( {{y_2} - {y_1}} \right)}^2}} }[/tex]
Given:
The coordinates of the vertices of the polygon are [tex]\left( { -2, 7} \right),\left( {2, 5} \right),\left( {- 1, 5} \right)[/tex], and [tex]\left( { - 1, 3} \right).[/tex]

The distance between points [tex]\left( { -2, 7} \right)[/tex] and [tex]\left( {2, 5} \right),[/tex] can be calculated as follows,
[tex]\begin{aligned}{\text{Distance}} &= \sqrt {{{\left( { - 2 - 2} \right)}^2} + {{\left( {5 - 7} \right)}^2}}\\&= \sqrt {16 + 4}\\&= \sqrt {20}\\&= 4.47\\\end{aligned}[/tex]
The distance between points [tex]\left( {2, 5} \right)[/tex] and [tex]\left( {- 1, 5} \right)[/tex] can be calculated as follows,
[tex]\begin{aligned}{\text{Distance}}&= \sqrt {{{\left( { - 1 - 2} \right)}^2} + {{\left( {5 - 5} \right)}^2}}\\&= \sqrt {9 + 0}\\&= \sqrt9\\&= 3\\\end{aligned}[/tex]
The distance between points [tex]\left( {- 1, 5} \right)[/tex], and [tex]\left( { - 1, 3} \right)[/tex] can be calculated as follows,
[tex]\begin{aligned}{\text{Distance}} &= \sqrt {{{\left( { - 1 + 1} \right)}^2} + {{\left( {3 - 5} \right)}^2}}\\&= \sqrt {0 + 4}\\&= \sqrt4\\&= 2\\\end{aligned}[/tex]
The distance between point [tex]\left( { -2, 7} \right)[/tex] and [tex]\left( { - 1, 3} \right)[/tex] can be calculated as follows,
[tex]\begin{aligned}{\text{Distance}} &= \sqrt {{{\left( { - 1 + 2} \right)}^2} + {{\left( {3 - 7} \right)}^2}} \\&= \sqrt {1 + 16} \\&= \sqrt {17} \\&= 4.13\\\end{aligned}[/tex]
The perimeter of the polygon can be calculated as follows,
[tex]\begin{aligned}{\text{Perimeter}} &= 4.47 + 3 + 2 + 4.13\\&= 13.6\\\end{aligned}[/tex]
Option (a) is not correct.
Option (b) is not correct.
Option (c) is not correct.
The perimeter of the polygon to the nearest tenth of a unit [tex]\boxed{13.6{\text{ units}}}.[/tex] Option (d) is correct.

6 sweets cost 24p altogether how much do 5 sweets cost
To calculate the cost of 5 sweets when 6 sweets cost 24p, divide the total cost by the number of sweets to determine the cost of one sweet, then multiply by 5. The cost for 5 sweets is 20p.
To find out how much 5 sweets cost when 6 sweets cost 24p altogether, we first need to calculate the cost of one sweet. We divide the total cost by the number of sweets to get the cost per sweet. Here's how it's done:
Find the cost of one sweet by dividing the total cost of 6 sweets (24p) by 6: Cost per sweet = 24p / 6 = 4p.Now, multiply the cost per sweet by the number of sweets you want to find the cost for, which in this case is 5: Cost for 5 sweets = 4p / sweet × 5 sweets = 20p.Therefore, 5 sweets would cost 20p.

The problem involves empirical probability. The table shows the breakdown of 95 thousand single parents on active duty in the U.S. military in a certain year. All numbers are in thousands and rounded to the nearest thousand. Use the data in the table to find the probability that a randomly selected single parent in the U.S. military is in the army.
The data provided does not include specific information needed to calculate the empirical probability of a randomly selected single parent in the U.S. military being in the Army.
Explanation:Unfortunately, the provided information does not give specific numbers for single parents actively serving in the different branches of the U.S. military, including the Army. Therefore, it is not possible to accurately calculate the empirical probability this question is asking for. However, if such data were available, you would calculate the empirical probability of a randomly selected single parent in the U.S. military being in the Army by dividing the number of single parents in the Army by the total number of single parents on active duty.

Suppose your total taxable income this year is $75,000. You are taxed at a rate of 10 percent on the first $25,000, 20 percent on the next $25,000, and 30 percent on the final $25,000. What is your total income tax?
The total income tax in the year is [tex]\boxed{\$ 15000}.[/tex]
Further explanation:
Given:
The total taxable income is [tex]\$75000.[/tex]
The rate of tax on the first [tex]\$25000[/tex] is [tex]10\%.[/tex]
The rate of tax on the next [tex]\$25000[/tex] is [tex]20\%.[/tex]
The rate of tax on the next [tex]\$25000[/tex] is [tex]30\%.[/tex]
Explanation:
The rate of tax on the first [tex]\$25000[/tex] is [tex]10\%.[/tex]
The income tax on the first [tex]\$25000[/tex] can be obtained as follows,
[tex]\begin{aligned}{\text{Income tax}}&=\frac{{10}}{{100}}\times 25000\\&= \$ 2500\\\end{aligned}[/tex]
The rate of tax on the next [tex]\$25000[/tex] is [tex]20\%.[/tex]
The income tax on the next [tex]\$25000[/tex] can be obtained as follows,
[tex]\begin{aligned}{\text{Income tax}}&= \frac{{20}}{{100}}\times 25000\\&=\$5000\\\end{aligned}[/tex]
The rate of tax on the next [tex]\$25000[/tex] is [tex]30\%.[/tex]
The income tax on the next \$25000 can be obtained as follows,
[tex]\begin{aligned}{\text{Income tax}}&=\frac{{30}}{{100}}\times 25000\\&=\$ 7500\\\end{aligned}[/tex]
The total income tax can be obtained as follows,
[tex]\begin{aligned}{\text{Total income tax}} &= \$ 2500 + \$ 5000 + \$ 7500\\&= \$ 15000\\\end{aligned}[/tex]
Hence, the total income tax in the year is [tex]\boxed{\$ 15000}[/tex].
