Jayana is trying to run a certain number of miles by the end of the month. If Jayana is 30% of the way to achieving her goal and she has already ran 9 miles, how many miles is she trying to run by the end of the month?
Answer: 30 miles
Step-by-step explanation: so first if Jayana is 30% of the way to achieving her goal and she has already ran 9 miles. You will have to convert 30% into a decimal. 30% is the same thing as 0.3 so, as that being said you will have to divide 9 by 0.3 because we are trying to find the miles.

Use complete sentences to describe why Set A={ XIX is an even whole number between 0 and 2) = ø
Answer:
True
Step-by-step explanation:
Set A contains an element x such that x is an even whole number between 0 and 2 is empty because there is only one whole number between 0 and 2 and that is 1. But 1 is not an even number. There is no even whole number between 0 and 2 therefore Set A = phi
An even number must be divisible by 2 but 1 is not divisible by 2. It is not an even number.
A whole number does not have fractions or decimal part. There is only one whole number between zero and two that is 1 which is not even.
Thus the given statement is true.

If BC = 61 and AB = 82, what is the length of AC?
Answer:
54.8
Step-by-step explanation:
Pythagorean theorem is a^2+b^2=c^2.
Plug the given values in to get 61^2+b^2=82^2
61^2 is 3,721 and 82^2 is 6,724.
6,724-3,721 is 3,003.
The square root of 3,003, rounded to a reasonable value, is 54.8.
The length of AC is 54.8.

If f(x)= x2 + 2x - 6 and g(x)= 3x2 - 5x - 7, find f(x)-g(x
Answer:
- 2x² + 7x + 1
Step-by-step explanation:
f(x) - g(x)
= x² + 2x - 6 - (3x² - 5x - 7) ← distribute parenthesis by - 1
= x² + 2x - 6 - 3x² + 5x + 7 ← collect like terms

a policeman and atheif are equidistant from the jewel bo upon considering jewel box as origin the position of policeman is(0,5).if the ordinate of the position of the theif is zero thn write the coordinates of the position of the theif
Answer:
(-5, 0) or (5, 0)Step-by-step explanation:
Coordinates given:
Policeman = (0, 5)Box with jewel = (0, 0)Thief = (x, 0)The distance from the policeman to the box with jewel is:
5- 0 = 5 unitsThe distance from the jewel box to the thief is also 5 units as they are both are equidistant from the jewel box
The x- coordinate is:
|x| = 5 ⇒ x = ± 5- 5 or 5 as it gives the same distance of 5 unitsSo his coordinates are (-5, 0) or (5, 0)

1. A school photo has dimensions of 2 1/4 inches by 2 3/4 inches. What are the dimensions of the school photo if enlarged by a scale factor of 7?
2. The scale on a map is 1 inch equals 2 1/2 miles. The distance between two streets on the map is 1 3/4 inches what is the actual distance between the streets?
Answer:
Step-by-step explanation:
2 1/4 *7=14 7/4 = 15 3/4
2 3/4 *7 =14 21/4 = 19 1/4
2 ) 1 in 2 1/2 miles
1 3/4 in ??
(2 1/2 * 1 3/4)/1 =
5/2 *7/4 =35/8 = 4 3/8
The enlarged area of the photo frame will be 43⁵/₁₆ square inches.
What is an expression?Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
The ratio of the scale of an original thing to a new object that is a representation of it but of a different size is known as a scale factor (bigger or smaller).
The area will be calculated as,
Area = 2¹/₄ x 2³/₄
Area = ( 9 / 4 ) x ( 11 / 4 )
Area = 99 / 16
Enlarged by factor 7.
Area = (99 x 7 ) / 16
Area = 43⁵/₁₆

Mark me as brainliast
As we can see, this is a 45 45 90 triangle
The legs of the triangle are equal and the hypotenuse = leg * sqrt(2)
In this case,
The hypotenuse = 6 * sqrt(2)
Cos(45) = 6 / (6 * sqrt(2))
The 6's cancel each other out and you're left with:
1 / sqrt(2)

Answer:
The value of k is 1.
Step-by-step explanation:
You have to apply Indices Law :
[tex] {a}^{m} \times {a}^{n} = {a}^{m + n} [/tex]
For this question :
[tex] {( \frac{4}{5} )}^{2} \times {( \frac{4}{5} )}^{5} = {( \frac{4}{5} )}^{6k + 1} [/tex]
[tex] {( \frac{4}{5}) }^{2 + 5} = {( \frac{4}{5}) }^{6k + 1} [/tex]
[tex]by \: comparison[/tex]
[tex]2 + 5 = 6k + 1[/tex]
[tex]7 = 6k + 1[/tex]
[tex]7 - 1 = 6k[/tex]
[tex]6k = 6[/tex]
[tex]k = 6 \div 6[/tex]
[tex]k = 1[/tex]
Answer:
k = 1
Step-by-step explanation:
[tex]a^{m} * a^{n} = a^{m+n}\\\\(\frac{4}{5})^{2}*(\frac{4}{5})^{5}=(\frac{4}{5})^{6k+1}\\\\\\(\frac{4}{5})^{2+5}=(\frac{4}{5})^{6k+1}\\\\(\frac{4}{5})^{7}=(\frac{4}{5})^{6k+1}[/tex]
Compare the powers,
6k + 1 = 7 {subtract 1 from both sides}
6k = 7 - 1
6k = 6 {Divide both sides by 6}
6k/6= 6/6
k = 1
