Step-by-step explanation:
1 Yes they are right angles, it is a right angle because you solve it with a Sine equation
2 the hypotenuse is the longest side
3. If the squares of the two shorter sides add up to the square of the hypotenuse, the triangle contains a right angle.
Write the slope-intercept form of the linear equation of a line with slope of -3/4 and a y intercept of (3,0)
Answers
Answer:
y= -3/4 +3
Step-by-step explanation:
slope-intercept form formula is y=mx+b
mx= slope
b= y-intercept
Therefore, if you input the numbers into the equation it is
y=-3/4 +3
it is 3 because this point is located at 3 on the y-axis
Item 9 Write an equation that you can use to find the value of x. Perimeter of triangle: 16 in.
Answers
Answer:
16 = 3x
Step-by-step explanation
Find the diagram attached.
Perimeter = sum of all its sides
Sum of all its sides= x+x+x
Sum of all its sides = 3x
Given perimeter = 16in
Equating both;
3x = 16
x = 16/3
x = 5.33in
Hence the value of x is 5.33 and the required equation is 16 =3x

HELP ASAP.!!!!!!! Jahlil is saving money at a constant rate to buy a new TV. After saving for $3$ months, Jahlil has $\$330$ . After saving for $5$ months, Jahlil has $\$510$ . Construct a function that models the relationship between the amount of money Jahlil has saved and the number of months he has saved for. Show or explain how you constructed the function. Respond in the space provided.
Answers
Answer:
y=90x+60
Step-by-step explanation:
x=months
y=dollars
Find dollars/month by finding the slope.
(3, 330), (5, 510)
-> (510-330)/(5-3) -> 90
Since its a constant rate, the function will be in the form, y=mx+b, and since we found the slope we can plug m=90.
y=90x+b
To find be, we simply substitute one of the points.
330=90(3)+b
b=60
Thus, plugging it in,
y=90x+60

Answer:
$30
Step-by-step explanation:
s = shorts
t = tshirts
s + 2t = 60
s + 3t = 75
s + 2t = 60
rewrite
-2t -2t
s = 60 - 2t
s + 3t = 75
plug in
(60 - 2t) + 3t = 75
solve
60 - 2t + 3t = 75
60 + t = 75
-60 -60
t = 15
s + 2t = 60
plug in
s + 2(15) = 60
s + 30 = 60

Maggie uses 6.9 pints of white paint and blue paint to paint her bedroom walls. 3 5 of this amount is white paint, and the rest is blue paint. How many pints of blue paint did she use to paint her bedroom walls?
Answers
Answer:
2.76 pints
Step-by-step explanation:
Given that:
Tottal amount of paint used = 6.9 pints
The faction of white paint used = 3/5
Hence, Amount of white Paint used :
3/5 * 6.9 = (3 * 6.9) / 5 = 4.14 pints of white paint.
Pints of blue paints used :
Total pints - pints of white used
6.9 - 4.14 = 2.76 pints of blue paint

$400 interest is earned on a principal of $2,000 at a simple interest rate of 5% interest per year. For how many years was the principal invested?
Answers
Answer:
4 years
Step-by-step explanation:
Given data
Simple interest= $400
Principal= $2000
Rate= 5%
The simple interest formula is given as
SI=PRT/100
substitute and solve for T
400=2000*5*T/100
cross multiply
400*100= 10000*T
40000=10000T
T= 40000/10000
T= 4 years
Hence the time taken is 4 years

Writing You want to buy a pet iguana that costs $50. You already have $16 and you plan to save $7
per week. If w represents the number of weeks until you have enough money to buy the iguana, what
equation could you use to find the value of w? Use pencil and paper. Explain how you could set up an
equation to find the amount of money you should save each week if you want to buy the iguana in
three weeks.
Answers
Answer:
50 = 16 + 7w
amount to save each week for 3 weeks = $11.33
Step-by-step explanation:
Cost of pet iguana = $50
Amount you have = $16
Savings per week = $7
Number of weeks = w
Equation:
50 = 16 + 7w
To find w
50 - 16 = 7w
34 = 7w
w = 34/7
w = 4.86
Approximately w = 5 weeks to the nearest whole week
if you want to buy the iguana in
three weeks
Let x = amount to save each week for 3 weeks
50 = 16 + 3x
50 - 16 = 3x
34 = 3x
x = 34/3
x = 11.33
amount to save each week for 3 weeks = $11.33
