= -32t +67
Answer:
−16[tex]t^{2}[/tex]+67Step-by-step explanation:
Review this code snippet: var time = 15; var greeting; if ( time < 12 ) { greeting = “good morning”; } else if ( time < 18 ) { greeting = “good afternoon”; } else { greeting = “good evening”; } console.log(greeting); What is the message that gets printed to the console?
Explanation:
We're given that time = 15
From this, we see that time < 12 evaluates to false, because 15 is not smaller than 12. Put another way, 15 < 12 is false.
But time < 18 is true since 15 < 18 is true. So we execute the second block of code and have the greeting variable be set to the string "good afternoon". This is what's displayed to the console without any quotes of course.
Write this sentence as an equation. What is m?
The sum of 11 and m is 15
Answer:
11+m = 15
m = 4
Step-by-step explanation:
Sum means add and is means equals
11+m = 15
Subtract 11 from each side
11+m-11 =15-11
m = 4

Answer:
1 1/2 cups
Step-by-step explanation:
We can use ratios to solve
2/3 cup seed x cups seed
-------------------- = -------------------
4 cups mix 9 cups mix
Using cross products
2/3 *9 = 4x
6 = 4x
Divide by 4
6/4 = x
1 2/4 =x
1 1/2 =x
A. 1/1/2 cups
Step-by-step explanation:
So we know:
2/3 cup of sunflower seeds = 4 cups of trail mix
We need to find:
? cups of sunflower seeds = 9 cups of trail mix
Firstly, we find how many cup of seeds for 1 cup of trail mix:
? cup of sunflower seeds = 1 cup of trail mix
This we do by:
2/3 ÷ 4 = 1/6
so now we got,
1/6 cups of sunflower seeds = 1 cup of trail mix
now multiply by what we need to find (the 9 cups of trail mix) so the full answer will be
2/3 ÷ 4 = 1/6
1/6 x 9 = 1/1/2

Monique borrows $5000 for 3 years at 8% per annum simple interest.
How much interest is she charged?
What total amount must she repay?
Answer:
1200 dollars for interest, she must pay 6200
Step-by-step explanation:
8 percent of 5000 is 400 times 3 (years) is 1200
Answers:
a) $1200 in interest is charged.b) $6200 must be paid back in total.=============================================
Work Shown:
a)
i = P*r*t
i = 5000*0.08*3
i = 1200 is charged in simple interest
---------------------------
b)
She must pay back the amount borrowed ($5000) which is the principal as well as the interest calculated in part a) earlier.
The total amount she must pay back is 5000+1200 = 6200 dollars

Which function has zeros at x = 10 and x = 2?
O f(x) = x2 - 12x + 20
O f(x) = x2 - 20x + 12
O f(x) = 5x2 + 40x + 60
O f(x) = 5x2 + 60x + 100
Answer:
f(x) = x² - 12x + 20
Step-by-step explanation:
f(x) = (x - 10)(x - 2)
f(x) = x² - 10x - 2x + 20
f(x) = x² - 12x + 20

Answer:That will be C
Step-by-step explanation:
It took Aiden 6 hours to plant 8 trees. How many hours would it take for him to plant 20 trees? 24, 18, 23, 15
================================================
Work Shown:
(6 hours)/(8 trees) = (x hours)/(20 trees)
6/8 = x/20
6*20 = 8*x ... cross multiply
120 = 8x
8x = 120
x = 120/8
x = 15
It takes him 15 hours to plant 20 trees.

I really need help with this
Answer:
A. x = 3, y = -3
B. a = -2, b = 5
C. try your best ill see u later
Step-by-step explanation:
Okay I'mma state some stuff first 3^a + 3^b = 3^(a+b)
and 3^a/3^b = 3^(a-b)
So first equation 3^3*3^-3=3^0
So second equation 3^3/3^-2 = 3^5
So third equation I dont really know the rule but I'mm just plug in a random number for g, like 2, then solve the thing like a normal equation.
So 3^-3 x f^-3 = 12^2 = 144, f^-3 = 144/(3^-3 or 1/27) = 144 x 27 = 3888
so f^-3 = 3888, f = well its an imaginary number according to calculator so u try your best on the last one

8. What is the equation of the line that passes through the points (0,5) and (1,7)
a. y = 3x - 3
b. y = 2x + 5
y = 4x - 1
d. y = 1/2x + 5
Answer:
B. y = 2x + 5
Step-by-step explanation:
Slope intercept formula y=mx+b
Slope formula y1-y2/x1-x2
First, let's find slope since we are provided 2 pairs of points, we can simply plug in our numbers in the Slope formula (y1-y2/x1-x2)
5-7/0-1
-2/-1
2/1
=2
Slope (m) = 2
Now using slope let's find our y-intercept (b) to plugin in our slope intercept formula (y=mx+b) for this let's use point 0,5
y=2x+b
5=2(0)+b
5=b
Y-intercept (b) = 5
Now let's plug in the slope (m) and the y-intercept (b) into the slope-intercept formula (y=mx+b)
y=mx+b
y=2x+5
So therefore our answer is B

triangle BCD is similar to triangle EFG. Find the measure of side FG. Round your answer to the nearest tenth if necessary.
Answer:
FG =41.1
Step-by-step explanation:
let FG be x
since they are similar triangles .We can take ratios
DC/FG = BC/EF
noe substitute the values
9/x = 7/32
do cross multiplication
x*7 = 9*32
x = 288/7
x = 41.1
The measure of side FG is 41.14.
What is a triangle?The polygon that has three sides and three vertices is called a triangle.
Since the two triangles are equivalent, their corresponding sides are proportional. So we can write
[tex]\frac{DC}{FG} =\frac{BC}{EF}[/tex]
Given that, DC =9, BC=7, and EF=32. By substituting these values, we get
9/FG = 7/32
FG=(9*32)/7=41.14
Hence, the value of side FG is 41.14.

Which of
below equations has a graph that passes
through the points (2, 3) and (0,-1) ?
Answer:
D
Step-by-step explanation:
Point slope formula y-y1=m(x-x1)
slope formula y1-y2/x1-x2
Points provided (2, 3) and (0,-1)
Let's find the slope. To find slope we need to plug in our numbers in the slope formula (y1-y2/x1-x2)
3-(-1)/2-0
4/2
=2
so slope (m) is 2
Now let's plug this in our point-slope formula (y-y1=m(x-x1)) with one pair of points (2,3)
y-3=2(x-2)
so, therefore, our answer is D!
