Answer:
So, his normal weight is 80 kg
Step-by-step explanation:
Let his normal weight be x
If the normal weight increasing percent now weighs
100 10 110
x 10 88
Now we can get a equation as,
[tex]100 = 110\\x = 88[/tex]
We can write this as a fraction
[tex]\frac{100}{x} = \frac{110}{88}[/tex]
You can use cross multiplication to solve this
[tex]88*100=110x\\8800=110x\\\frac{8800}{110} =\frac{110x}{110} \\80kg = x[/tex]
Hope this helps you.

You save $1400 from a summer job. You decide to put it into an account that earns simple annual interest. After 9 months, your balance is $1421. Find the annual interest rate.
Answer:
2%
Step-by-step explanation:
Calculate annual interest amount first:
annual interest x 9/12=21
Annual interest =21x12/9
annual interest amount=$28
calculate annual interest rate
1400 x interest rate = annual interest
$1400 x interest rate = $28
interest rate =$28/1400
interest rate=.02 or 2%
PLEASE HELP !!!!!!!! What is the equation of the directrix for the following parabola: -8(x-5)=(y+1)^2
a. y=-3
b. x=7
c. y=7
d. x=-3
Answer:
x=7
Step-by-step explanation:
The directrix of the equation is x=7
What is directrix of parabola?The directrix of a parabola is a line that is perpendicular to the axis of the parabola. The directrix of the parabola helps in defining the parabola. A parabola represents the locus of a point which is equidistant from a fixed point called the focus and the fixed line called the directrix. The directrix and the focus are equidistant from the vertex of the parabola. Here we define the directrix for the standard equations of a parabola.
The directrix of the parabola y^2 = 4ax, having x-axis as its axis, passes through (-a, 0), and has the equation x + a = 0.The directrix of the parabola y^2 = -4ax, having x-axis, passes through (a, 0), and has the equation x - a = 0.The directrix of the parabola x^2 = 4ay, having y-axis as its axis, passes through (0, -a), and has the equation y + a = 0.The focus of the parabola x^2 = -4ay, having y-axis as its axis, passes through (0, a), and has the equation y - a = 0.Given:
-8(x-5)=(y+1)²
Now, using the definition of directrix
x= 8/4 +5
x= 2+ 5

-5 = x
Answer:
x = -5
Step-by-step explanation:
4x - 3 = 6x + 7
Add 3 to both sides to isolate the variable:
4x = 6x + 10
Subtract 6x from both sides to keep x on 1 side:
-2x = 10
Divide by -2 to have the base value of x:
x = -5

Joe, Marty, and Sally all decide to buy a new car for $15,000. Each one decides to pay for their car in a different way. Compare each of their stories and decide who you think made the best decision when they bought their car.
Joe decided he wanted to pay cash for his car, so he saves $1,000 per month until he has enough money in the bank to buy the car. How long will it be before Joe can buy his car?
Answer: 15 months
Step-by-step explanation: bc if you multiply 15 times the amount he is saving a month which is $1,000. you multiply them two together and get 15,000. (sorry if i over explained it)
A basketball is thrown upward from a height of 6 feet at an initial speed of 15 feet per second. As the basketball travels, Earth's gravity slows it down.
The height of an object dropped from a height of 6 feet is given by h(t)=−16t2+6.
The distance in feet traveled by an object at a constant speed of 15 feet per second is given by d(t)=15t.
These two functions can be combined to build a new function, f, that models the height of the basketball as a function of time in t seconds.
Which choice shows how to combine h and d to build f
Answer: f(t)=h(t)+d(t)
f(t)=-16t^2+15t+6

Keisha took out a loan for 10,500 and was charged simple interest at an annual rate of 8.8%. The total interest she paid on the loan was $462. How long was the loan for, in months?
Answer: 6 months
Step-by-ste
462=(10,500)(0.88)t
462=924t
462/924=t
0.5=t
So the loan was 0.5 year's
Since we assume that there are 12 months in a year, the loan was 0.5 .12=6 months

A quadrilateral is inscribed in a circle. Find the measure of each missing angle as labeled below. Show your work and/or explain how you got your answer.
1 point for each correct angle measure and 1 point for explaining or showing how you got your answer. Don’t forget to label your answers.
Answer:
C = 95°
D = 72°
F = 108°
Step-by-step explanation:
Opposite angles of an inscribed quadrilateral are supplementary. Inscribed angles are half the measure of the arc they subtend. (The latter statement can be used to prove the former one.)
Using these relations, we have .
C = 180° -E = 180° -85° = 95°
D = 144°/2 = 72°
F = 180° -D = 180° -72° = 108°
