Answer:
70%
Step-by-step explanation:
Two Steps to Convert a Fraction to a Percent
Use division to convert the fraction to a decimal:
7/10 = 7 ÷ 10 = 0.7
Multiply by 100 to get the percent value:
0.7 × 100 = 70%
Therefore the answer is 70%.

what is 62.5% as a decimal
Answer:
0.625
Step-by-step explanation:
please give me brainliest :(
Answer:
0.625
Step-by-step explanation:
How to Convert a Percent to a Decimal
Here are two ways to convert a percent to a decimal,
1. Divide a percent by 100 and remove the percent sign to convert from a percent to a decimal.
Example: 62.5% becomes 62.5/100 = 0.625
2. This way is easier and faster. Start by removing the percent sign and moving the decimal point 2 places to the left.
Example: 62.5%
⇒ 62.5
⇒ 6.25
⇒ .625
Hence, the answer is 0.625.

Which inequality represents all values of x for which the quotient below is defined? Square root 7x2 divide by square root 3x
Inequalities help us to compare two unequal expressions. The correct option is D.
What are inequalities?Inequalities help us to compare two unequal expressions. Also, it helps us to compare the non-equal expressions so that an equation can be formed. It is mostly denoted by the symbol <, >, ≤, and ≥.
The given expression can be solved as,
[tex]\dfrac{\sqrt{7x^2}}{\sqrt{3x}}\\\\= \dfrac{\sqrt{7}x}{\sqrt{3x}}\\\\= \sqrt{\dfrac{7x}{3}}[/tex]
Since the value of (7x/3) is needed to be positive, therefore, the inequality that represents all the values of x for the quotient is defined as x>1.
Hence, the correct option is D.

What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
In an equation, the expressions on either side of the equals sign are called the left-hand side (LHS) and the right-hand side (RHS), respectively. The equals sign (=) indicates that the two expressions have the same value, and that the equation is true for certain values of the variables involved.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. It typically consists mathematical operations, such as addition, subtraction, multiplication, division, and exponentiation.

Does anybody know this? ABCD is a parallelogram BDC=110. Find the following values,
Answer:
see explanation
Step-by-step explanation:
in a parallelogram]
• opposite sides are congruent
• opposite angles are congruent
• consecutive angles are supplementary , sum to 180°
• diagonals bisect each other
Then
DC = AB = 15
BC = 2 × WC = 2 × 9 = 18
∠ BAC = ∠ BDC = 110°
∠ DCA = 180° - 110° = 70°
DC = 15 (opposite sides in a parallelogram is parallel and equal to each other)
BC = 18 (the diagonals in a parallogram bisect at their midpoints -> BW = WC = 9 -> BC = 9 + 9 = 18)
angle BAC = 110 (opposite angles are equal to each other)
angle DCA = 70 (consecutive angles add up to 180, angle BAC and angle DCA are consecutive -> 180 - 110 = 70)

From the graph, we read the slope of line JK.
slope = rise/run = -3/-6 = 1/2
The equation we need has the same slope.
y = mx + b
y = (1/2)x + b
It passes through point P(6, -2). Now we find b.
-2 = (1/2)(6) + b
-2 = 3 + b
b = -5
The equation is
y = (1/2)x - 5

What is a translation?A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.
In this problem, we have a trigonometric function, with amplitude of 1, hence there was no vertical translation, which removes options a and b.
The function is of zero at the origin, 1 at [tex]\frac{\pi}{2}[/tex] and -1 at [tex]\frac{\pi}{2}[/tex]. The sine function is of 0 at [tex]-\pi[/tex], of -1 at [tex]-\frac{\pi}{2}[/tex] and of 1 at [tex]-\frac{3\pi}{2}[/tex], hence option d is correct.

Serena is taking 4 friends on a trip with her to Louisiana for spring break. They take two cars to the airport where Serena pays $7.00 per car to park. Serena is charged a total of $2114.00 for tickets and parking. She pays the same price for each plane ticket. Using an equation to help you solve, what was the price of each person’s ticket?
Answer:
$420
Step-by-step explanation:
number of people = 5 (4 friends + serena)
number of cars = 2
cost of parking = 7 for each car = 7 * number of cars = 7 * 2 = 14
let t be the cost of each ticket
cost of tickets = t for each person = t * 5
total cost = cost of parking + cost of tickets
= 14 + t * 5
= 2114
2114 = 14 + 5t
subtract 14 from both sides to isolate the variable and its coefficient
2100 = 5t
divide both sides by 5 to isolate t
t = 2100/5 = 420

What is convergent of a series?A series is convergent if the series of its partial sums approaches a limit; that really is, when the values are added one after the other in the order defined by the numbers, the partial sums getting closer and closer to a certain number.
We are assuming the:
[tex]=\int\limits^0_{-\infty} {\theta e^{\theta}} \, d\theta[/tex]
Applying limit;
[tex]=\lim_{n \to \infty} \int\limits^0_{-n} {\theta e^{\theta}} \, d\theta[/tex]
After solving the integral:
[tex]=\lim_{n \to \infty} (e^{\theta})|^0_-_p[/tex]
= -(1-0)
= -1
