A ) 40° because an acute angle is less than a 90° angle.. so on a protractor it should be more than 0° but less than 90°.

The definition of an acute angle is one where the angle measurement, obtained by looking at the measure between 2 legs or terminals in a quadrant would be one where the angle measure is less than 90 degrees, anywhere from 0 - 90 not including 90 would be an acute angle.

In this case, it would be A. 40 degrees.

If venom A is four times as potent as venom B and venom C is 2.5 times as potent as venom B. How many times as potent is venom C

weqwewe [10]

Answer:

Venom C is 0.625 times as potent as venom A.

Step-by-step explanation:

We are given that venom A is four times as potent as venom B.

Venom C is 2.5 times as potent as Venom B.

We have to find that how many times as potent is venom C is compared to venom A.

Let Venom B =x

Then Venom A= $4\times x=4x$

Venom C= $2.5\times x=2.5 x$

$\frac{Venom\;C}{venom\;A}=\frac{2.5x}{4x}=\frac{25}{40}=\frac{5}{8}=0.625$

Hence, venom C is 0.625 times as potent as venom A.

vova2212 [387]

Answer:

There is no answer to this question.

Step-by-step explanation:

Chelsea and Ming are selling pies for a school fundraiser. Customers can buy blueberry pies and lemon pies. Chelsea sold 7 blueb

riadik2000 [5.3K]

Answer:

The cost of 1 blueberry is $7

The cost of 1 lemon pie is $17

Step-by-step explanation:

Given as :

The number of blueberry sold by Chelsea = 7

The number of lemon pie sold by Chelsea = 10

The number of blueberry sold by Ming = 5

The number of lemon pie sold by Ming = 1

The total selling amount of Chelsea = $219

The total selling amount of Ming = $52

Let The cost of 1 blueberry = b

And The cost of 1 lemon pie = l

Now, According to question

For Chelsea

7 b + 10 l = $219 ..................1

For Ming

5 b + 1 l = $52 .................2

Solving both equations

10×(5 b + 1 l ) - (7 b + 10 l) = 10×52 - 219

Or, 50 b + 10 l - 7 b - 10 l = 520 - 219

Or, (50 b - 7 b) + (10 l - 10 l) = 301

Or, 50 b - 7 b+ 0 = 301

Or, 43 b = 301

∴ b = $\frac{301}{43}$

I.e b = $7

So, The cost of 1 blueberry = b = $7

Put the value of b in eq 2

So, 5 × 7 + 1 l = $52

or, 35 + l = $ 52

Or, l = 52 - 35

∴ l = $17

So, The cost of 1 lemon pie = l = $17

Hence The cost of 1 blueberry is $7

And The cost of 1 lemon pie is $17 Answer

area of parallelogramis 30 cm^2. if the length of two adjacent sides are 6 cm and 10 cm respectively. find its diagonal

GrogVix [38]

Answer:

the long diagonal d=15.49 ( rounded to the nearest hundredth)

the shortest d=√136-120(cos 30)=5.663 ( rounded to the nearest hundredth)

Step-by-step explanation:

Area=height * base

30=h*6

h=30/6=5 cm

height=asinФ

sinФ=5/10=1/2 (Ф=30)

alternate angle=180

180-30=150 degrees

diagonal²=a^2+b^2-2abcos150

d²=10²+6²-2(10)(6)(-√3/2)

d=√136+60(√3)

the long diagonal d=15.49 ( rounded to the nearest hundredth)

the shortest d=√136-120(cos30)=5.663

Which expression represents the 4th term in the binomial expansion of (e+2f)^10

butalik [34]

The answer depends on what is meant by the "fourth term". By the binomial theorem, one answer could be

$\dbinom{10}3e^3(2f)^{10-3}=120e^3(2f)^7=15360e^3f^7$

By symmetry, another could be

$\dbinom{10}3(2f)^3e^{10-3}=960e^7f^3$
