Step2247 [10]

Answer: x ≥ 40

Step-by-step explanation:

Hi, to answer this question and write the inequality we have to analyze the information given:

Each afternoon at least 40 people buy coffee in a coffee shop

In Math, at least means more or equal (≥).

So, if X represents the number of people who buy coffee in an afternoon, the inequality is (Mathematically speaking) :

X ≥ 40

a bird of species a when diving can travel four times as fast as a bird of species b top speed if the total speeds of these two

weeeeeb [17]

X will be the speed of species b and 4x will be the speed of species a:

x + 4x = 180
5x = 180
x = 180 / 5
x = 36 m/h

If species b has a speed of 36 m/h, the speed of species a is 4 times that:

4 x 36 = 144 m/h.

Answer:

$\boxed {\bf A~=~36~m/h~and~B~=~144~m/h}$

Hope it helped,

Happy homework/ study/ exam!

Quadrilateral MBPV is similar to quadrilateral GKDF. BP = 78 mm, KD = 30 mm , and FD = 45 mm. What is VP? Enter your answer in t

vlada-n [284]

Answer:

VP = 117 mm

Step-by-step explanation:

Corresponding sides of similar quadrilaterals are proportional.

VP/FD = BP/KD

VP = FD·BP/KD = (45 mm)·(78/30) . . . . multiply by FD; fill in the givens

VP = 117 mm

The numbers of bags of crisps sold per day in a general shop was recorded over 13 days.

Alona [7]

I just figured it out so I’ll answer it on this account lol.

Q1 = 32, Q2 = 45, Q3 = 52

Interquartile range = 52 - 32 = 20

Range = 68 - 21 = 47

Solve the formula for the indicated variable. EASY 40 POINTS!!!!!!!!!!!!!!!!

vlada-n [284]

Answer:

d = Nc + x

Step-by-step explanation:

Given

N = $\frac{d-x}{c}$

Multiply both sides by c to clear the fraction

Nc = d - x ( add x to both sides )

Nc + x = d
