Lara wrote the following statement: "You can only draw one unique isosceles triangle that contains an angle of 75°." Which statement is true? Lara is correct, because only one unique triangle can be drawn with the given information. Lara is incorrect, because the triangle described cannot be drawn with the given information. Lara is incorrect, because more than one triangle can be drawn with the given information. None of the above.

Answer:

x = 54°.

Step-by-step explanation:

As we know, angles in a triangle add up to 180 degrees. a right angle is equal to 90 degrees so we know that the right angle is already 90 degrees. Now, we add the other angle we know, 36 degrees, to the 90°. this gives us 126 degrees. to work out angle x we need to 180 - 126. this will give you 54 degrees. We take the 126 degrees away to give us the remaining angle in the triangle.

Answer:

54 degrees

Step-by-step explanation:

If there are 180 degrees in a triangle and one of the points are 36 degrees then you need to figure out how much a right angle is... it is 90 degrees. 36 degrees + 90 degrees = 126 degrees. 180 degrees - 126 degrees = 54 degrees.

Part A: The correlation coefficient of r = 0.51 is accurate based on the scatter plot given.

Part B: A scenario that would be a causal relationship can be quantity of fertilizer used vs kg of pumpkins picked on the farm.

The association between two variables that are correlated can be shown by a scatter plot which has a trendline along which the data points are located.

If the trendline slopes upwards from the left to the right, it shows a positive correlation and vice versa.

Also, if the farther the data points are to each other along the trendline, the farther is it the correlation coefficient, r, is from 1 or -1. If they are moderately apart,, the correlation coefficient would be somewhere around 0.5/-0.5 and 0.65/-0.65, as the case may be.

Answer:

Step-by-step explanation:

THIS MIGHT NOT BE WHAT YOU ARE LOOKING FOR AND MIGHT NOT BE CORRECT! READ FIRST!

The answer is A. The slope of the line is rise/run = 4/2 = 2.1. This means that each kilometer costs $2.10. The y-intercept is 2.1, which means that the initial fee is $2.10. So the correct statement is: The slope is 2.1. This means that each kilometer costs $2.10.

The other statements are incorrect. The slope is not 5, so each kilometer does not cost $5. The y-intercept is not 5, so the ride does not last 5 kilometers. The y-intercept is the value of the function when the input is 0, which in this case is the initial fee of $2.10.

Answer:

Step-by-step explanation:

Given that,

→ Magazine = $5

→ Total cost = $25

→ 1 eraser = x

The equation will be,

→ 4x + 5 = 25

Now the value of x will be,

→ 4x + 5 = 25

→ 4x = 25 - 5

→ x = 20/4

→ [ x = $5 ]

Hence, value of x is $5.

Answer:

25%x5.25

125%x5.25

Step-by-step explanation:

Markup means increases the price, so you should be able to find the answers

Answer:

25%x5.25

125%x5.25

Step-by-step explanation:

To estimate the volume using the Midpoint Rule with \(\displaystyle n=5\), we need to divide the interval \(\displaystyle 0\leq x\leq 1\) into \(\displaystyle n\) subintervals of equal width. Since \(\displaystyle n=5\), each subinterval will have a width of \(\displaystyle \Delta x=\frac{1-0}{5}=\frac{1}{5}\).

Now, let's calculate the volume using the Midpoint Rule. The formula for the volume obtained by rotating about the y-axis is:

\(\displaystyle V\approx 2\pi \sum _{i=1}^{n}y_{i}\Delta x\)

where \(\displaystyle y_{i}\) represents the value of the function \(\displaystyle y=\sqrt{1+x^{3}}\) evaluated at the midpoint of each subinterval.

First, let's find the midpoints of the subintervals. Since the width of each subinterval is \(\displaystyle \Delta x=\frac{1}{5}\), the midpoint of the \(\displaystyle i\)-th subinterval is given by:

\(\displaystyle x_{i}=\frac{\Delta x}{2}+\left( i-\frac{1}{2}\right) \Delta x=\frac{1}{10}+\left( i-\frac{1}{2}\right) \frac{1}{5}\)

Substituting \(\displaystyle x_{i}\) into the function \(\displaystyle y=\sqrt{1+x^{3}}\), we obtain:

\(\displaystyle y_{i}=\sqrt{1+\left( \frac{1}{10}+\left( i-\frac{1}{2}\right) \frac{1}{5}\right) ^{3}}\)

Now, we can calculate the approximate volume using the Midpoint Rule:

\(\displaystyle V\approx 2\pi \sum _{i=1}^{5}y_{i}\Delta x\)

Substituting the values of \(\displaystyle y_{i}\) and \(\displaystyle \Delta x\) into the formula, we can evaluate the sum and compute the estimated volume.

Assign the numbers to the number line in the following order:

2.15=2.15

220%=2.2

9/4=2.25

*2.15* is easy enough to place as it is already in decimal form. However, the other 2 options need to be converted to decimals in order to be placed. We have the fraction 9/4 and percentage 220%. 9/4 can either be simply divided on a calculator or turned into the mixed fraction 2 and 1/4, which is *2.25*. Finally, we know that converting a decimal to a percentage we multiply the decimal by 100. Therefore, to convert a percentage to a decimal we divide 100 or move the decimal to the left 2 places. With this conversion rule, 220% transforms to *2.2* and we have the third and final number for our number line. Arranging these three numbers from least to greatest:

2.15, 2.2, 2.25

(a) Christine will decompose the shape into 2 trapezoid

(b) Christine will need 29 square feet area of carpet

area of the trapezoid is calculated using the formula: 1/2 × (AB + CD) × height, where AB and CD are the lengths of its parallel sides.

(a). The shape will be decomposed into two (2) trapezoid

(b). For the bigger trapezoid;

8ft 6in = 8.5 ft

area of bigger trapezoid = 1/2 × (8.5 + 12) × 2 ft²

area of bigger trapezoid = 20.5 ft²

For the smaller trapezoid;

2ft 6in = 2.5 ft

area of smaller trapezoid = 1/2 × (2.5 + 6) × 2 ft²

area of smaller trapezoid = 8.5 ft²

Total square feet area of carpet = 20.5 ft² + 8.5 ft²

Total square feet area of carpet = 29 ft²

Answer:

Step-by-step explanation:

If the dilated image is smaller than the original, then 0<k<1.

Meaning the scale factor is less than one, but greater than zero.

You would mulitply each coordinate by this scale factor - to obtain the coordinates of the dilated figure.

Let's choose   \(\frac{1}2}\).

In the original figure Point A = (-4,3) dilating by \(\frac{1}{2}\) results in A' being (-2, 1.5).  When you multiply each cooordinate (-4,3) by one half.

Applying the scale factor of one half to the other coordinates - yields these results.

Point B (4,3) becomes Point B' (2, 1.5)

Point C (-4,-4) becomes Point C' (-2,-2).

Point D (4, -4) becomes Point D' (2,-2)

Step-by-step explanation:

50.2 = 5.02 × 10¹

1102 = 1.102 × 10³

so,

50.2 × 1102 = 5.02 × 1.102 × 10³×10¹ =

= 5.02 × 1.102 × 10⁴

so, the decimal point moves 3 positions to the right :

55,320.4

The expression 4x + 3y - 16 has three terms. The terms are:

4x (the term with the coefficient 4 and the variable x)

3y (the term with the coefficient 3 and the variable y)

-16 (the constant term with the coefficient -16)

There are 3 terms. The 2 terms are 4x, 3y, and -16. They’re the invidual expressions separated by a + or - sign.

Here are the pairs matched with their products:

- (-5)(4.2) matches with -21

- (-7)(-3) matches with 21

- (2.5)(-9) matches with -22.5

Pairs (4) and (5) do not have corresponding products in the given options.

Answer: 26

We would add the total responses recorded in the Girls row, which is equal to 32. We would then subtract it from the total of that row, 38. 38 - 32 is equal to 6. 6 girls chose their answer as English. We can check our work by adding the responses to see if they added up to the total. Now we move to the boys. The Maths column is 5. The boys row is missing 2 things - english and total. We can find the total by subtracting 38 from 70. This is equal to 32. Now, we can add 7 and 5 (12) and subtract from the row total (32). This is equal to 20. 20 boys chose English.

Now we add the girls and boys. 6 + 20 is equal to 26. 26 is your answer.
