Sara bought one bunch of lettuce for $1.60. How many bunches can she get if she has $24?
Answer:
38.40
Step-by-step explanation:
If you multiply 1.60 by 24 it will get you 38.40
Answer:
15 bunches
Step-by-step explanation:
So if each bunch of lettuce costs $1.60, you can divide that by 24, which is the amount of money you have, to get 15 bunches.
[tex]\frac{1.60}{24}[/tex] = 15

Which line shows the first error in the solution? Three more than a number divided by 4 is -12. What is the number?
Explanation:
On the third line is where the student went from -12-3 to -9. This is not correct. Instead, it should be -12-3 turning into -15.
Think of it like being 12 feet under water (the number -12) and then moving 3 more feet deeper under water. You'll move down 3 to get to -15 to represent being 15 feet under water. Use a vertical number line if needed.
You can also compute -12-3 like 12+3 = 15, then just make everything negative. So -12-3 = -15

Elizabeth uses 33.15 ounces of granola for 15 servings of trail mix.
If each serving contains the same amount of granola, how much granola is in each
serving?
Answer:
Step-by-step explanation:
We have to do 33.15 / 15 to find how much is in each.
We change 33.15 into a fraction
We get 33 3/20
We do 33 3/20 / 15 = 33 3/20 * 1/15 = 663/20 * 1/15 = 663/300 = 2 63/300
Therefore, 2 63/300 ounces of granola is in a serving.

(x,y)=(5,-3)Ivan is curious if he can run faster than a rabbit.
He runs `90` feet in `5` seconds. The average rabbit can run at a speed of `35` feet per second.
Is Ivan faster than the rabbit?
Answer:
Step-by-step explanation:
Speed of rabbit per second = 35 ft
Ivan:
Speed in 5 seconds = 90 ft
Speed in 1 second = 90 ÷ 5 = 18 ft
No, Ivan is not faster than rabbit.
Let 0 be an angle in quadrant 3 such that cos0=-5/13.
Find the exact values of csc0 and tan0
Answer:
see explanation
Step-by-step explanation:
Given
cosθ = - [tex]\frac{5}{13}[/tex]
This is a 5- 12- 13 right triangle
with adjacent = 5, opposite = 12 and hypotenuse = 13
In quadrant 3
sinθ < 0 and tanθ > 0 , then
sinθ = [tex]\frac{opposite}{hypotenuse}[/tex] = - [tex]\frac{12}{13}[/tex] and
cscθ = [tex]\frac{1}{sin0}[/tex] = [tex]\frac{1}{-\frac{12}{13} }[/tex] = - [tex]\frac{13}{12}[/tex]
then
tanθ = [tex]\frac{sin0}{cos0}[/tex] = [tex]\frac{-\frac{12}{13} }{-\frac{5}{13} }[/tex] = - [tex]\frac{12}{13}[/tex] × - [tex]\frac{13}{5}[/tex] = [tex]\frac{12}{5}[/tex]

A right triangle has side lengths 7, 24, and 25 as shown below.
Use these lengths to find tanA, sinA, and cosA.
9514 1404 393
Answer:
tan(A) = 7/24sin(A) = 7/25cos(A) = 24/25Step-by-step explanation:
The mnemonic SOH CAH TOA can help you remember the trig ratios:
Sin = Opposite/Hypotenuse
Cos = Adjacent/Hypotenuse
Tan = Opposite/Adjacent
With respect to angle A, the sides are Adjacent = 24; Opposite = 7, Hypotenuse = 25. Then the desired trig ratios are ...
tan(A) = 7/24
sin(A) = 7/25
cos(A) = 24/25

In ANOP, NP is extended through point P to point Q, m_OPQ = (9x – 19)°,
mZPNO = (2x + 5), and mZNOP = (3x + 16º. Find mZNOP.
Answer:
The values of x and y are x = 6 and y = 9Step-by-step explanation:
MNOP is a parallelogram its diagonal MO and PN intersected at point A
In any parallelogram diagonals:
Bisect each other
Meet each other at their mid-point
In parallelogram MNOP
∵ MO and NP are its diagonal
∵ MO intersect NP at point A
- Point A is the mid-point pf them
∴ MO and NP bisect each other
∴ MA = AO
∴ PA = AN
∵ MA = x + 5
∵ AO = y + 2
- Equate them
∴ x + 5 = y + 2 ⇒ (1)
∵ PA = 3x
∵ AN = 2y
- Equate them
∴ 2y = 3x
- Divide both sides by 2
∴ y = 1.5x ⇒ (2)
Now we have a system of equations to solve it
Substitute y in equation (1) by equation (2)
∴ x + 5 = 1.5x + 2
- Subtract 1.5x from both sides
∴ - 0.5x + 5 = 2
- Subtract 5 from both sides
∴ - 0.5x = -3
- Divide both sides by - 0.5
∴ x = 6
- Substitute the value of x in equation (2) to find y
∵ y = 1.5(6)
∴ y = 9
The values of x and y are x = 6 and y = 9

Consider the function F(x)= x³ +½x² −2x +3. Use calc and algebra to find any and all stationary points on the graph of the function.Precalc need help ASAP
Solution:
the above function has more than one root or more than one solution. The derivative of the function represents the slope of the tangent line to the curve
F(x)= x³ +½x² −2x +3, F'(x) = 3(x3-1)+(1/2)(2)(x2-1)-2(x1-1)+0
F'(x)=3x2+x-2 is the slope of the tangent line
setting the slope =0 and solving the quadratic equations, you find all the
critical points of interest
3x2+x-2=0, solve by factoring (3x-2)(x+1)=0, then 3x-2=0, x= 2/3
and x+1=0, x=-1 substituting these values of x in the original equation
you get the corresponding values of F(x) such that;
F(x)= x³ +½x² −2x +3, F(x)=(2/3)3+1/2(2/3)2-2(2/3)+3
= 8/27+4/18-4/3+3 = 8/27+2/9-4/3+3/1 = 59/27 and the first point is
(2/3, 59/27)
F(x)= x³ +½x² −2x +3, F(x)=(-1)3+1/2(-1)2-2(-1)+3
= -1+1/2+2+3 = 9/2 and the 2nd point is ( -1, 9/2)
these two points represents points where the slope of the tangent line to the curve is 0 and could be either maximum or minimum points
You can also find the y intercepts where x = 0 F(x)= x³ +½x² −2x +3, setting x = 0, y= F(x)=3 and the point ( 0,3) is a y intercept setting y = 0, then x intercepts can be found upon solving the equation x³ +½x² −2x +3 =0

2. A scuba diver dove 48 feet in 4 minutes.
What integer represents his change in depth
for each minute?
A. 52 feet per minute
B. 44 feet per minute
C. -12 feet
per
minute
D. -48 feet per minute
Answer:
C. -12 feet per minute
Step-by-step explanation:
This question is really just asking for the slope of this situation. So the best way to find the answer is to find the change in y over the change in x. In this case, y is the depth and x is the time. So, it would be -48/4 because the diver went down 48 feet when 4 minutes passed. Then, simply divide, -48/4, which equals -12 feet/1 minute.
