Kate scored 85,78,72, and 81 on 4 math tests. What score does she need on the fifth test to have at least an 80 average?
Elan Coil [88]

I am not good in this kind of question so maybe 84?

suppose the full marks for each of them is 100 so for 5 of them it will be 500 cause if you if you multiply 100 full marks by 5 it will be 500

so the answer to this question is maybe 84?

cause if you add all of them with 84 the outcome will be 400 and if you divide the 400 by 5 it will be 80

Find the coordinates of quadrilateral PQRS with vertices P(1, 4), Q(-1, 4), R(-2, -4) and S(2, -4) under the translation (x,y)--
Georgia [21]
We apply the rule to each of the vertices:
 (x, y) ---> (x-5, y + 3)
 P (1,4) ---> (1-5,4 + 3) >> (-4, 7)
 Q (-1,4) ---> (-1-5,4 + 3) >> (-6, 7)
 R (-2, -4) ---> (-2-5, -4 + 3) >> (- 7, -1)
 S (2, -4) ---> (2-5, -4 + 3) >> (-3, -1)
 Answer:
<span> a.
 P’(-4, 7), Q’(-6, 7) , R’(-7, -1) and S’(-3, -1)</span>

How much will each person get if 4 people share 1/2 pound of grapes equally
dsp73
Divide amount of grapes by number of people.

= 1/2 lb ÷ 4 people

to divide a fraction, multiply by the reciprocal (inverse)

= 1/2 * 1/4
= (1*1)/(2*4)
= 1/8 pound

ANSWER: Each of the 4 people will get 1/8 pound of grapes.

Hope this helps! :)

Consider the following.3x + 3y = 8(a) Find y' by implicit differentiation.(b) Solve the equation explicitly for y and differenti
ludmilkaskok [199]

Answer:

a.y'=-1

b.y'=-1

c.Yes

Step-by-step explanation:

We are given that consider a function

3x+3y=8

Implicit function: That function is a relation in which dependent variable can not be expressed in terms of independent variable

Explicit function: It is that function in which dependent variable can be expressed in terms of independent variable.

a.3x+3y=8

Differentiate w.r.t x then we get

3+3\frac{dy}{dx}=0

3\frac{dy}{dx}=-3

\frac{dy}[dx}=\frac{-3}{3}=-1

\frac{dy}{dx}=y'=-1

b.3x+3y=8

3y=8-3x

y=\frac{8-3x}{3}

Differentiate w.r.t x then we get

\frac{dy}{dx}=\frac{-3}{3}=-1

\frac{dy}{dx}=y'=-1

When we substituting the value of y obtained from part b into a solution of part a then we get

y'=-1

Hence, solutions are consistent.
