Answer:
y = 12,58 unitsStep-by-step explanation:
y = opposite
15 = hypotenuse
θ = 57°
therefore we use sin
sinθ = opposite/hypotenuse
sin57° = y/15
y = 15sin(57°)
y = 12,58 units

Lucas wants to have at least $4,000 in his account. He has $2,500 to deposit into an account that earns simple interest at a rate of 6%. What is the fewest number of years it will take Lucas to reach his goal?
Answer:
6.25 years
Step-by-step explanation:
Simple interest = principal x time x interest rate
simple interest = $4,000 - $2,500 = $1,500
1500 = $4,000 x 0.06 x n
1500 = 240n
divide both sides by 240
n = 6.25 years
Consider the expression 9a^3b^6(3a^3b^2+7a^2b^2)-(5a^4b^4)^2 select the equivalent expression in standerd form
Answer:
[tex]27a^6b^8 + 63a^5b^8 - 25a^8b^8[/tex]
Step-by-step explanation:
Given
[tex]9a^3b^6(3a^3b^2+7a^2b^2)-(5a^4b^4)^2[/tex]
Required
Simplify
[tex]9a^3b^6(3a^3b^2+7a^2b^2)-(5a^4b^4)^2[/tex]
Open both brackets
[tex]9a^3b^6*3a^3b^2+9a^3b^6*7a^2b^2-5a^4b^4*5a^4b^4[/tex]
This gives

which equation can be used to determine the value of x?
Answer:
choice 1) 2x + 40 = 180
Step-by-step explanation:
(x + 10) + (x + 30) = 180
2x+ 40 = 180
Answer:
X+30+x+10=180
combine like terms
2x+40=180
subtract 40 from both sides
2x=140
divide by 2
x=70
but for you it is 2x+40=180

I need help with the first question pls
Answer:
67.5 feet
Step-by-step explanation:
If 1 inch = 9 feet, and the model is 7.5 inches,
you just need to do 7.5 • 9 = 67.5 feet.
OR
7 • 9 = 63 and 1/2 (or .5) • 9 = 4.5
63 + 4.5 = 67.5
*I'm pretty sure it says 1 inch = 9 feet and I'm also basing this off the fact that your work for question 2 is showing the same ratio of 1 inch = 9 feet
please please help !!
Step-by-step explanation:
As the problem said, you need to submit a picture of your own work, but I can help nevertheless.

A sample in a laboratory starts with 8 bacteria. The bacteria grow at a rate of 3.2% every hour. How many hours until the sample has grown to 140,000
bacteria? (Round to the nearest whole number)
A 46
B 3
C) 305
D 133
Answer:
probably C
Step-by-step explanation:
The question can be written as:
8 * 1.032^n = 140 000, this can be rearranged to
140 000/8 = 17500 = 1.032^n
now we need to find n, we could do this manually with a calculator, but an easier method is to use [tex]\log_x(y)[/tex]
example of log
2^3 = 8
log2 (8) = 3
log1.032 (17500) = 310.17
A train travels 423 miles every 9 hours. What is the unit rate of the train?
Answer:
47 mph.
Step-by-step explanation:
The unit rate would be in mph.
Divide 423 miles with 9 hours:
423/9 = 47
47 mph, or miles per hour, is your answer.
~
Given that: Train travels 432 miles in every 4 hours
To Find: Unit rate of the train
⠀⠀⠀⠀⠀⠀__________________
Solution:-
we can find the unit rate of train by divide the distance and time.
⠀⠀
[tex]:\implies\sf{speed(v)} \: = \dfrac{distance(s)}{time(t)} [/tex]
[tex]:\implies\sf Speed\; (v) = \dfrac{423}{9}[/tex]
[tex]:\implies\sf Speed \: (v) = 47 \;mph\;(miles\;per\;hour)[/tex]
⠀⠀⠀⠀
[tex]\therefore \underline {\sf{Hence \: , \: \pmb{47mph} \: is \: the \: required \: answer}}[/tex]

Jose had a rectangular piece of paper that
was 80 mm long and 70 mm wide. He cut
the paper in half. What is the area of each
half of the paper in square millimeters?
A. 5600 sq mm
B. 2800 sq mm
C. 140 sq mm
D. Not here
Answer:
B. 2800 sq mm
Step-by-step explanation:
Given the following data;
Length = 80 mm
Width = 70 mm
Area of rectangle is given by the formula;
Area of rectangle = length * width
Substituting into the formula, we have;
Area of rectangle = 80 * 70
Area of rectangle = 5600 mm²
Since the paper (area of rectangle) was halved, we would divide by 2;
Area of each half = 5600/2
Area of each half = 2800 sq mm.

(-3 + 4) x 66 + -19 x 8 - 2
Answer:
-88
Step-by-step explanation:
(-3 + 4) x 66 + -19 x 8 - 2
According to PEMDAS (or GEMDAS), you start with the parenthesis. So you do the equation in the parenthesis.
-3+4= 1
Now you replace it with your answer.
1 x 66 + -19 x 8 - 2
You next do multiplication.
1*66=66
66+ -19 x 8 -2
Multiplication again
-19*8=-152
66 + -152 - 2
Now there is only addition and subtraction left so you solve left to right.
66 + -152= -86
-86-2=-88
The answer is -88

HELP PLZ AGAIN. Same material. It is still timed. Will give 50 pts and brainly. This is vital to my math grade. Time is on the essence and my math grade is at stake if I do not pass this. I need Slope Intercept form for the equation. HELP HELP HELP PLZ.
Answer:
y = 4x - 9
Step-by-step explanation:
y = 4x + 2
the the slope m is 4
the new line which paraller to the first one will have a slope 4 too
M = 4
then, the new slope-intercept form which pass through (x1,y1), in this case (5,-4) is
y - y1 = M(x - x1)
y - (-4) = 4(x - 5)
y + 4 = 4x - 5
y = 4x - 5 - 4
y = 4x - 9
Answer:
Step-by-step explanation:
FYI only
Slopes of parallel lines are the same and y-intercepts are different
( [tex]x_{1}[/tex] , [tex]y_{1}[/tex] )
y - [tex]y_{1}[/tex] = 4( x - [tex]x_{1}[/tex] )
From - 12 surface sea level, a submarine descends 20 feet per minute. Where is the submarine in relation to sea level 7 minutes after it starts descending?
Answer:
-152 feet in relation to sea level.
Step-by-step explanation:
If it descends 20 feet per minute, you just multiply the distance by the minutes. So 20x7 and you will get 140. You can't forget that it's already -12 below sea level, so it's 12 feet deeper. It's -152 feet in relation to sea level.

Answer:
A; x< 5
Step-by-step explanation:
A simple way to remember the difference between greater than or less than is picturing the symbol as an alligator, the mouth of the alligator, the open end, eats the bigger number. The line under the greater than/ less than symbol means "or equal to". An open circle on a number line means that it's NOT "or equal to", so the answer isn't B or D. On the number line, it shows what x could equal. The arrow falls on 0, I'll use 0 as an example. Is 0 less than 5? Yes. If x could equal 0, that means that x is less than 5.
