Answer:

Step-by-step explanation:

A perpendicular bisector is a line segment that goes form a vertex to its opposite side. The important characteristic is that a perpendicular bisector intersects the opposide at the mid point and with a right angle, that's why is called perpendicular and bisector.

So, Andrew can conclude that side BC is divide equally, that is, BD = DC.

Therefore, the right answer is the second choice.

Based on the given information after drawing the triangle Andrew can conclude only  BD = DC.

Use the concept of triangle defined as:

A triangle is a three-sided polygon, which has three vertices and three angles which has a sum of 180 degrees.

Given that,

Andrew draws triangle ABC.

He constructs a perpendicular bisector from vertex A.

The perpendicular bisector intersects side BC at point D.

Based on Andrew's drawing,

He can conclude that BD is equal to DC.

The perpendicular bisector from vertex A divides side BC into two equal parts, making BD and DC congruent.

However, Andrew cannot conclude that AB is equal to BC,

AD is equal to BC, or AC is equal to BC based on the given information.

Hence,

For this triangle Andrew can conclude only BD = DC.

Answer:

$1.57

Step-by-step explanation:

2.09 × 3/4 = 1.5675, rounded to 1.57

Answer:

I believe the answer is $1.57 about. The answer is longer but that is rounded.

Step-by-step explanation:

I just did 3/4 times 2.09 and got 1.57 because if a whole pound is 2.09 then 3/4 times the whole pound would give you 3/4 of the price.

The reciprocal of the given decimal number -0.07 is decimal number -14.3.

The given decimal number is -0.07.

The reciprocal of any quantity is, one divided by that quantity. For any number ‘a’, the reciprocal will be [tex]\frac{1}{a}[/tex]. If the given number is multiplied by its reciprocal, we get the value 1.

The given decimal written in fraction as [tex]-\frac{7}{100}[/tex].

Reciprocal of [tex]-\frac{7}{100}[/tex] is [tex]-\frac{100}{7}[/tex]

[tex]-\frac{100}{7}=-14.285[/tex]

Final answer:

The reciprocal of -0.07, when rounded to one decimal place, is -14.3.

Explanation:

To calculate the reciprocal of any number, you simply divide 1 by that number.

The reciprocal of a number is the multiplicative inverse of that number.

In this case, for the number -0.07:

The reciprocal of -0.07 is calculated as follows:

Divide 1 by -0.07:

1/-0.07

= -100/7

= - 14.2857 which equals approximately -14.2857.

To round the result to one decimal place, we consider the first decimal digit after the point, which is 2. Since 2 is less than 5, we don't round up the preceding digit.

Round this number to one decimal place, giving us -14.3.

Therefore, the reciprocal of -0.07, correct to one decimal place, is -14.3.

Answer:

-1/14

Step-by-step explanation:

To simplify the expression, you should first divide up the parts to make it easier.  Multiply 1/5 by  -5/7 first.  When you multiply the two fractions, the fives cancel out since there is a five in both the numerator and the denominator.  This leaves us with just -1/7.

[tex]\frac{1}{5} *\frac{-5}{7} =\frac{-1}{7}[/tex]

Now, multiply -1/7 by 2/4.  Notice that you can simplify 2/4 to 1/2.  You can't cancel out anything in this expression so simply multiply the two fractions.

[tex]\frac{-1}{7} *\frac{1}{2} =-\frac{1}{14}[/tex]

I moved the negative sign from the numerator out front, but you don't have to do that.

14.95

Step-by-step explanation:

Use a median calculator

Final answer:

To find the number in the middle of 8.6 and 21.3, you calculate their average by adding them together and dividing by two, resulting in 14.95.

Explanation:

To calculate the number in the middle of 8.6 and 21.3, we need to find the average of these two numbers. To do this, you add the two numbers together and then divide by two.

The calculation is therefore: (8.6 + 21.3) / 2.

Adding 8.6 and 21.3 gives us 29.9, and dividing 29.9 by 2 gives us 14.95. So, 14.95 is the number in the middle of 8.6 and 21.3.

Final answer:

To determine Miguel's total cost including the 8% sales tax, add the pre-tax total of $20.98 to the sales tax amount, which is calculated as $20.98 multiplied by 0.08, totaling $22.66.

Explanation:

To calculate Miguel’s total cost including an 8% sales tax on his purchases, follow these steps:

First, find the total cost before tax by adding the prices of the items. If Miguel bought items totaling $20.98, this is the pre-tax total.

Next, convert the tax percentage to a decimal form. For an 8% sales tax, this is done by dividing by 100, which gives us 0.08.

Then, calculate the amount of sales tax by multiplying the pre-tax total by the decimal tax rate: $20.98 × 0.08 = $1.6784.

Round the sales tax to the nearest cent, which gives us $1.68.

Finally, add the sales tax to the pre-tax total to find the total cost: $20.98 + $1.68 = $22.66.

The total cost for Miguel after adding the 8% sales tax is $22.66.

i times the square root of 3

Step-by-step explanation:

Whenever you take a square root of a number, look for anything that you could take out! Like if you have the square root of 40, that’s 4 * 10, so you could take out a 2 from the square root and leave the 10.

In this, we see that it’s the square root of 3 times the square root of -1, which we can simplify to the square root of 3 times “i.” We use i to represent the square root of -1.

Answer:

$241.58

Step-by-step explanation:

he amount of money A, accrued at the end of n years when a certain amount, P is invested at a compound annual rate, r, is given by:

[tex]A=P(1+r)^n[/tex]

From the given information:

P =$150

r=10%=0.1

n= 5 years

Therefore the balance after 5 years is:

[tex]A=P(1+r)^n\\=150(1+0.1)^5\\=150*1.1^5\\=\$241.58[/tex]

The balance of the account after 5 years, with an initial investment of $150 and an annual interest rate of 10%, compunded annually, would be approximately $241.58.

To find the balance of the investment after 5 years, we substitute the values into the given formula. P is the principal amount which is $150, r is the annual interest rate which is 10% or 0.10 in decimal form, and n is the number of years which is 5. So the formula becomes A = $150 * (1 + 0.10)^5.

To simplify, calculate 1 + 0.10 to get 1.1. Then raise 1.1 to the power of 5 to get 1.61051. Multiply that by $150 to get approximately $241.58. So, the balance of the investment after 5 years would be approximately $241.58.

The diameter of the cone is 4√3 cm, which is approximately 6.93 cm when rounded to two decimal places.

To find the diameter of the cone, we first need to identify the formula for the volume of a cone, which is V = (1/3)πr^2h. Given that the volume (V) of the ice cream cone is 12π cubic cm and the height (h) is 9 cm, we can set up the equation to solve for the radius (r):

12π = (1/3)πr^2(9)

We can simplify this equation by dividing both sides by π and multiplying both sides by 3/9 (which is the reciprocal of 1/3 times 9):

12 = r^2

Therefore, r = √12 cm. To find the diameter, which is twice the radius, we calculate:

Diameter = 2r = 2(√12) cm = 2(√4√3) cm = 4√3 cm

The diameter of the cone is 4√3 cm or approximately 6.93 cm when rounded to two decimal places.

False - Linear is a proportional relationship as it is a straight line.

False.

False. A proportional relationship is linear. In a proportional relationship, when one variable increases or decreases, the other variable also increases or decreases at a constant rate. This results in a straight-line graph passing through the origin (0,0). In contrast, a non-linear relationship does not exhibit constant rate of change and does not form a straight line when graphed.
