There is a kind of fruit, yellow. It's a bit like banana, but it's twice as small as banana. It doesn't have thick skin like banana, and it still has a bad smell What kind of fruit is it? .

Should be egg yolk fruit, skin is thin, break open inside is yellow, like boiled eggs
The fruit is oval or oval in shape, with a long tip at the top. The mature fruit has orange yellow and smooth outer skin, orange yellow flesh with powdery tissue. It is soft and lack of water. It is very similar to boiled egg yolk, with a slightly sweet taste. It contains a seed with oval shape and sharp ends. It is native to tropical America

If the solution set of inequality 2x + a > 4 + 3a is x > - 1, then the value of a is

Analysis
2x+a>4+3a
∴
2x+a-4-3a>0
2x-2a>4
x-a>2
x>a+2
∴
a+2=-1
a=-3

Write the following exponential formula as logarithm formula (1) the third power of 2 = 8 (2) the fifth power of 2 = 32 (3) the negative first power of 2 = half
(4) One third of 27 = one third

If the exponential function a ^ B = x, then the inverse function of the exponential function loga x = B
(1)
2^3=8
log2 8=3
(2)
2^5=32
log2 32=5
(3)
2^(-1)=1/2
log2 1/2=-1
(4)
27^(-1/3)=1/3
log27 (1/3)=-1/3

A fruit shop bought 300 kg of watermelon, and sold one sixth of the total on the first day, one fourth of the total on the second day, and one fourth of the total on the third day
It is known that 100 kg is sold in the third day. How much is sold in the first, second and fourth days?
How many kilos of watermelon are left?

50.,75,25,50

A 12 hours to do 8 parts, B 13 hours to do 5 parts, a, B work efficiency ratio is ()
A. 3:2B. 8:5C. 16:15

8 △ 12 = 16 (pieces) 5 △ 13 = 15 (pieces) the work efficiency of Party A: the work efficiency of Party B = 16:15; therefore: C

It is known that the effective value of a sinusoidal alternating current electromotive force is 220 V, the frequency is 50 Hz, and the initial phase is 30 degrees

Em=200√2v
T=1/f=1/50=0.02s
ω=2πf=100π rad/s

A, B and C rent a taxi together for an outing. A pays half of the total money of the other two, and B pays one third of the total money of the other two,
I paid 40 yuan. How much does it cost to rent the car? I want an explanation of the origin of each figure (except for the conditions in the original question),

40÷1/3=120
A + C = 120
B = 40
A total of 120 + 40 = 160 (yuan)

The square matrix a satisfies the square of a + A + e = 0, proves that a is invertible, and finds the negative power of A

Because a ^ 2 + A + e = 0
So a (a + e) = - E
So a is reversible
And a ^ - 1 = - (a + e) = - a-e

We know that z.w is a complex number, (1 + 3I) × Z is a pure imaginary number, w = Z / 2 + I, and the absolute value of W is equal to 5 √ 2
w=z/(2+i)

First of all, I'm sorry to ask you a question. The plural number can't test the absolute value. So you should see the sign of the module, that is, the module of W is equal to 5 √ 2

Class 1 of Grade 8 should take a group photo when they go out on holiday. If a color negative costs 0.57 yuan, a developing one costs 0.35 yuan, and each person should book one, and the cost is not more than 0.45 yuan, then there are at least () students taking the group photo?
A. 5B. 6C. 7D. 8

According to the meaning of the question, we can get: 0.57 + 0.35x ≤ 0.45X, the solution is: X ≥ 5.7, at least 6 students take the group photo
