Answer: 30 mph
Step-by-step explanation: As we know: the formula for Average Speed (AS) is Average Speed = Total Distance ÷ Total Time.
Since we don't know exactly how far Jen needed to drive, our distance there will be 1, and since we don't know how long it took to get there, we will put 1 as well.
Now we have to state the distance and time to get back. The distance will stay the same so we keep it 1. Now it is stated that when returning, it took Jen 3 times slower to get back, so we do 1 × 3 (because it took her longer) and get 3.
Next, we substitute: AS=TD÷TT ⇒ AS= (1+1) ÷ (1+3) = 2 ÷ 4= 1/2 or 1.4
Since our given beginning speed was 60mph, we need to multiply by 1/2 to get the final answer:
1/2 x 60 = 30

Which of the following sets are continuous? Check all that apply.
A. {2, 4, 6, 8, ...)
B. (-0, +00)
C. (30, 45]
D. [60, 100)
E. {3,7)
Answer: The correct answer option is B.
Step-by-step explanation:
We are to determine whether which of the given data sets in the answer options are continuous.
For this, we need to know what a continuous data set is.
A data set that has no definite end to its value but keeps on continuing.
Here, the data sets are given in A, C, D, and E have definite starting and ending points.
While B is a continuous set as its values are continuing to infinity.

how do i do this, my son is struggling and he needs help
Answer:
32
Step-by-step explanation:
angle a is the outside angle. It creates a circle that will always equal 360 degrees. Since the outside angle is 302, the inside angle must be 58 degrees (360-302). The top square angle will be 90 degrees (a square angle is always 90 degrees). Since the angles in a triangle always add up to 180 degrees, we need to add 58 and 90, and then subtract it from 180, which equals 32. So, angle x equals 32.
Answer:
x = 32°
Step-by-step explanation:
The triangle is 58°. I know this because the question stated that "a" is 302. A full circle is 360. So you can subtract 360 - 302 = 58. There is a small corner of a square in the other side of the triangle. With that we know that, that side has to be 90°. A triangle is 180° total. So we can subtract:
180 - 90 - 58 = 32
Therefore, x = 32°

Which equations may be used to determine the 3 consecutive integers whose sum is 127?
Answer:
a and b.
Step-by-step explanation:
I’ll explain by giving an example.
Let’s say that: a=3;b=4;c=5; => they all are consecutive -> their sum is 12.
=> if we use a) n=3 => 3*n+3=3*3+3=12 => correct.
b) n+(n+1)+(n+2)= 3+4+5=12=> correct.
c)n+2n+3n=3+6+9=18=>incorrect.
d)3n=3*3=9=>incorrect.
The side of one square is 2 centimeters longer than the side of the second square. If the sum of their
areas is 100cm?, find the length of the side of each square.
*DUE TOMORROW* please help
Answer:
Side length of first square is 10 cm
Side length of second square is 8 cm
Step-by-step explanation:
Let (x + 2) = side length of first square
Let x = side length of second square
Area of a square = (side length)²
⇒ area of first square = (x + 2)²
⇒ area of second square = x²
If the sum of their areas is 100 cm² then:
⇒ (x + 2)² + x² = 100
Expand the brackets:
⇒ x² + 4x + 4 + x² = 100
Collect and combine like terms:
⇒ 2x² + 4x + 4 = 100
Subtract 100 from both sides:
⇒ 2x² + 4x - 96 = 0
Divide both sides by 2:
⇒ x² + 2x - 48 = 0
Factor:
⇒ (x - 6)(x + 8) = 0
Therefore,
⇒ x = 6, x = -8
As distance is positive, x = 8 only.
Therefore, side length of first square is 10 cm
Side length of second square is 8 cm
Family spends $240.000 per week on food. If this is 6% of their income,what is their income??
their income is "x", which oddly enough is the 100% of their income, we also know that 16% of it 240 bucks, so
[tex]\begin{array}{ccll} amount&\%\\ \cline{1-2} x&100\\ 240&16 \end{array}\implies \cfrac{x}{240}=\cfrac{100}{16}\implies 16x=24000 \\\\\\ x=\cfrac{24000}{16}\implies x=1500[/tex]

Answer:
Pictured this you have 3/4 of a sandwich and eat half of that 3/4 of the sandwich. you know have eaten 3/8 of a full sandwich and have 3/8 left.
if we were to actually divide 3/4 by 1/2 we would get 1.5 or 1 1/2 which would not make sense, so instead, we multiply and get 3/8

The number that gives a value of 25 when 1/4 of the number is added to 4 is 80.
What is the number?The first step is to represent the information in the question as an equation:
1/4x + 5 = 25
In order to determine the number, take the following steps:
Combine similar terms
1/4x = 25 - 5
Add similar terms
1/4x = 20
Multiply both sides of the equation by 2
x = 80

8x18÷4+15 use pemdas right answers only please
Answer:
51
Step-by-step explanation:
PEMDAS means parenthesis (there are none), exponents (there are none), multiplication. So you multiply 8x18 to get 144. Then you have division, so 144/4 is 36. Finally, you add this number to 15 to get 51 as your final answer.
By PEMDAS, the solution of the expression 8x18÷4+15 is 51.
What is PEMDAS?The abbreviation PEMDAS is used to indicate the sequence of steps to be taken when resolving expressions with multiple operations. P is for "parentheses," E is for "exponents," M is for "multiplication," D is for division, A is for addition, and S is for subtraction.
Given:
An expression,
8x18÷4+15.
In order to solve the problem by PEMDAS:
First, solve the multiplication operation,
144÷4+15
Now, solving division operations,
36 + 15
Applying addition operation,
51
Therefore, 51 is the solution to the expression.

what is the perimeter of an equilateral triangle whose height is 2 square root of 3
Answer:
the answer for this is 12
Answer:
Step-by-step explanation:
If we half the base of the equilateral triangle, which has a length of xcm, we can form a right-angled triangle with a base of x/2 cm and height 2√3 cm.
Now using Pythagoras' Theorem we solve for the hypotenuse:
[tex]x^{2} = (\frac{x}{2})^{2} + (2\sqrt{3})^{2}\\ x^{2} = \frac{x^{2}}{4} + 12\\ 4x^{2} = x^{2} + 48\\ 3x^{2} = 48\\ x^{2} = 16\\x = \frac{+}{}4\\ \\[/tex]
x must be positive as it is a length so we multiply 4 by 3 to get the perimeter of 12.

a fifty-four hundredths
b four and five-tenths
c fifty-four tenths
d five and four-tenths
[tex]\\ \tt\hookrightarrow 0.54[/tex]
Fifty-four hundredths[tex]\\ \tt\hookrightarrow \dfrac{54}{100}[/tex]
More simplify
[tex]\\ \tt\hookrightarrow \dfrac{27}{50}[/tex]
Solution:
Since there is two digits on the right of the decimals, it is called "the hundredths."
=> 1 digit on the right of decimal - tenths=> 2 digits on the right of decimal - hundredths=> 3 digits on the right of decimal - thousandths=> 4 digits on the right of decimal - ten thousandthsNow, we can recite 0.54 as 54 hundredths. The word "54 hundredths" defines 54/100. Hence, Option A is correct.

=> 54/100 = 27/50
