Answer:
the amount of vanilla teaspoons needed for the amount of flour
Step-by-step explanation:
how do you simplify this?
Answer:
tan x
Step-by-step explanation:
(tan-x)[sec(pi/2)-x] (sin-x)
We know that tan (-x) = - tan (x) and sin (-x) = - sin (x)
-(tanx)[sec(pi/2)-x] -(sinx)
(tanx)[sec(pi/2)-x] (sinx)
Using the identity sec = 1/ cos
sec ( pi/2 -x) =1/cos ( pi /2 -x)
We know that cos (s-t)=cos (s) cos(t) + sin (s) sin (t)
1/ ( cos pi/2 cos x + sin pi/2 sin x) = 1/(0 cos x - 1 sinx) = 1 / sinx
Replacing into the equation
(tanx)[1/ sinx] (sinx)
tan x

Can someone please help me with these two problems
Answer:
no
yes
Step-by-step explanation:
y < 5x - 4
1 < 5(1) - 4
1 < 1
This is not a true statement. 1 cannot be less than 1 itself so the answer is no.
7x - 4 < 28
7(0) - 4 < 28
-4 < 28
This is a true statement so the answer is yes.

1. Ed Shapiro works as an office manager. His annual salary is $48,300. What is his monthly salary?
Answer:
The answer is $4025
Step-by-step explanation:
In this problem we are given his annual salary. meaning per year. to find how much he makes in a month, we must divide by how many months there are in a year.
there are 12 months in a year.
so, 48300/12= 4025
hope this helps!
Answer:
$4,025 is his monthly salary.
Step-by-step explanation:
Annual salary means yearly. Since there are 12 months in a year, you would just take his annual (yearly) salary and divide it by 12 in order to get his monthly salary. Thus it would be:
[tex]\frac{48300}{12} =4025[/tex]

In my opinion, I'd say A and C aren't functions, but B is a function.
The reason being is because every "X" value has a "Y" value. For those that don't have exactly 1 "Y" value aren't functions.
A. has more "Y" values than "X" values, so that proves not to be a function.B. Has "X" values that are exactly appointed to a "Y" value.C. Has one "X" value that's missing, and a "Y" value that doesn't exist.Hope this helps!

A researcher needs 25 mL or 45%
base Solution for a certain
expiriment, but she has only 15%
Solution and 65% Solution. How
many mL of the 15% and the
65% Solutions should she mix to
get what She needs?
Answer:
10 mL of 15% solution
15 mL of 65% solution
Step-by-step explanation:
If x is the volume of 15% solution, and y is the volume of 65% solution, then:
x + y = 25
0.15 x + 0.65 y = 0.45 (25)
Solve with substitution:
0.15 x + 0.65 (25 − x) = 0.45 (25)
0.15 x + 16.25 − 0.65 x = 11.25
0.50 x = 5
x = 10
y = 15

I need help with these 2 questions, please help me.
Answer:
The probability of the spinner landing on 2 is one fourth.
Step-by-step explanation:
The spinner is split into 4 equal parts labeled 1, 2, 3, 4
The probability of the spinner landing on 2 is given as:
(Possibility of it landing on 2) ÷ (Total possible outcome)
The total possible outcome is 4, because the spinner could land on 1, or 2, or 3, or 4.
It can only land on 2 once, so the possibility of it landing on 2 is 1.
Probability = 1/4

Isolate the variable by dividing each side by factors that don't contain the variable.
Answer:
d) x = 4/3
Step-by-step explanation:
Given equation,
→ -x + (3/7) = 2x - (25/7)
Now the value of x will be,
→ -x + (3/7) = 2x - (25/7)
→ -x - 2x = -(25/7) - (3/7)
→ -3x = -28/7
→ -3x = -4
→ x = -4/-3
→ [ x = 4/3 ]
Hence, the value of x is 4/3.
