Answer:

34 degrees.

Step-by-step explanation:

Assuming AK is a straight line and being shown angle JDK is right and 90 degrees it can be stated that 4x + (3x-8) = 90 degrees.

Drop the parentheses and get 7x - 8 = 90.

Add 8 to both sides 7x = 98.

Divide both sides by 7, x = 14.

Plug that x value into (3x-8), [3(14)-8] = 34 degrees.

Answer:

34 degrees

Step-by-step explanation:

So, because mJDK and mJDA lie on a line, they must be supplementary, and since mJDK is 90 degrees, mJDA must be too. So, you know that the combination of mADC and mCDJ must be 90 degrees. 4x+3x-8=90 simplified is 7x=98, which says that x is equal to 14. So you plug in the values for 3x-8, and voila! mCDJ is 34!

Given:

An exponential function goes through points (0,6) and (5, 6144).

To find:

The exponential function.

Solution:

The general form of an exponential function is

[tex]y=ab^x[/tex]          ...(i)

It goes through points (0,6) and (5, 6144). It means the equation must be satisfied by these two points.

Putting x=0 and y=6, we get

[tex]6=ab^0[/tex]

[tex]6=a[/tex]

Putting a=6, x=5 and y=6144, we get

[tex]6144=6b^5[/tex]

[tex]\dfrac{6144}{6}=b^5[/tex]

[tex]1024=b^5[/tex]

Taking 5th root on both sides, we get

[tex]\sqrt[5]{1024}=b[/tex]

[tex]4=b[/tex]

Putting a=6 and b=4, we get

[tex]y=6(4)^x[/tex]

Therefore, the required exponential function is [tex]y=6(4)^x[/tex].

a. Any number that is not the minimum or maximum could be removed without changing the range.

b. Removing the number 97 changes the range.

What is set ?

In mathematics, a set is a collection of distinct objects, called elements or members, that are treated as a single entity. Sets can contain any type of object, such as numbers, letters, or other mathematical objects.

To find a number that could be removed from the data set without changing the range, we need to determine the minimum and maximum values in the set. In this case, the minimum value is 53 and the maximum value is 97, so any number that is not the minimum or maximum could be removed without changing the range. For example, we could remove the number 85:

53 54 63 63

68 68 68 74

82 85 92 88

89 92 92 97

The range of the data set is still 97 - 53 = 44.

To find a number that could be removed from the data set that would change the range, we need to identify a number that is either the minimum or maximum value. For example, we could remove the number 97:

53 54 63 63

68 68 68 74

82 85 85 88

89 92 92

b. The range of the data set is now 92 - 53 = 39, which is smaller than the original range of 44.

Therefore, removing the number 97 changes the range.

Answer:

He spent 150% than what he estimated.

Step-by-step explanation:

15 ÷ 10 = 1.5 = 150%

Answer: 66.67%

Step-by-step explanation: The first step is to divide 10 by 15 to get the answer in decimal form: 10 / 15 = 0.6667 Then, I multiplied the answer from the first step by one hundred to get the answer as a percentage: 0.6667 * 100 = 66.67%

Answer: -12

Answer:

-12 degrees

Step-by-step explanation:

Fahrenheit and Celsius

10 degree fahrenheit

What is the celsius?

____________________

Take a look at the picture with the information provided, we see that f is the vertical line while c is the horizontal line. Since we are looking for 10 degree fahrenheit, let's find it on the vertical line. If we look at the red line, when it goes across 10 fahrenheit, the approximate part that it hits celsius is -12 degrees.

Answer:

7/2 = 35/10 & 3/5 = 6/10

Step-by-step explanation:

This is very hard to be explained, sorry.

Answer:

The first one:   35/10

Second:   6/10

Step-by-step explanation:

These are the answers because since you are trying to solve to get a denominator of 10, you must multiply both the to and bottom numbers by whatever you need to get the denominator to 10.  For example, for 3/5 you would multiply both the top and bottom numbers by 2, because you nned to multiply the denominator by 2 to get 10.

Answer:

24

Step-by-step explanation:

We are given a strand of numbers and are asked to find the mode.

To find mode, we have to see which number appears the most within the number strand, let's start with ordering the numbers from least to greatest.

20, 22, 23, 24, 24, 25, 46

Looking at the strand we see that 24 appears the most, therefore 24 is the mode.

Answer:

24

Step-by-step explanation:

Put the numbers in order.

20, 22, 23, 24, 24, 25, 46

Count how many of each number.

20

22

23

24, 24

25

46

The number that appeared the most is the mode.

24 appeared twice and the other numbers appeared only once.

Step-by-step explanation:

Given:

The center of the circle = (-1,0)

Point on the circle = (2,-4).

To find:

The equation of the circle.

Solution:

Distance between two points is

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Distance between the center (-1,0) and the point on the circle (2,-4) is the radius of the circle.

[tex]r=\sqrt{(2-(-1))^2+(-4-0)^2}[/tex]

[tex]r=\sqrt{(2+1)^2+(-4)^2}[/tex]

[tex]r=\sqrt{(3)^2+(-4)^2}[/tex]

On further simplification, we get

[tex]r=\sqrt{9+16}[/tex]

[tex]r=\sqrt{25}[/tex]

[tex]r=5[/tex]

Now, the equation of the circle is

[tex](x-h)^2+(y-k)^2=r^2[/tex]

Where, (h,k) is the center and r is the radius of the circle.

The radius of the circle is 5 and the center is at (-1,0), so the equation of the circle is

[tex](x-(-1))^2+(y-0)^2=5^2[/tex]

[tex](x+1)^2+y^2=25[/tex]

Therefore, the first option is correct, i.e., [tex](x+1)^2+y^2=25[/tex].

1 3/4 = 1.75

8 times 1.75 = 14

So If Hannah weighed 7.2 lb at birth during the six months that are shown on the table hanna puts on 8.7 during those six months so if we’re estimating what her weight will be at her one year visit

8.7(what she put on during the six months)+ 15.9 (her weight now)= 24.6

Answer: I estimate she will weigh 24.6lb at her one year visit
