Answer:

Option A, C and E

Step-by-step explanation:

We have to find points which are solution to the linear inequality ( y<0.5x + 2)

(a) For (-3, -2)

-2 < (0.5 × 3 + 2)

-2 < 1.5 + 2

-2 < 3.5

True, It's a solution.

(b) For (-2, 1)

1 < 0.5 × (-2) + 2

1 < -1 + 2

1 < 1

False, it's not a solution

-2 < 0.5 (-1) +2

-2 < -1 + 2

-2 < 1

True, It's a solution.

(d) For (-1, 2)

2 < 0.5 (-1) + 2

2 < -1 + 2

2 < 1

False, It's not the solution.

(e) For (1, -2)

-2 < 0.5 (1) + 2

-2 < 2.5

True It's a solution

Therefore, Option A, C and E are the solutions.

The radius of the base is 10 cm.

Solution:

Height of a cone = 15 cm

Volume of the cone = 1570 cm³

To find the radius of the base of the cone:

Volume of the cone = $\frac{1}{3}\pi r^2 h$

$$\Rightarrow \frac{1}{3}\pi r^2 h=1570$

$$\Rightarrow \frac{1}{3}\times\ 3.14\times r^2 \times 15=1570$

$$\Rightarrow\ 3.14\times r^2 \times 5=1570$

$$\Rightarrow\ 15.7\times r^2 =1570$

Divide by 15.7 on both side of the equation, we get

$$\Rightarrow r^2 =100$

Taking square root on both sides of the equation, we get

⇒ r = 10

Hence the radius of the base is 10 cm.

Answer:

d. about 50 times larger

Step-by-step explanation:

The given expressions for magnitude (M) can be solved for the intensity (I). Then the ratio of intensities is ...

$\dfrac{I_2}{I_1}=\dfrac{I_0\cdot 10^{M_2}}{I_0\cdot 10^{M_1}}=10^{M_2-M_1}=10^{4.2-2.5}\\\\=10^{1.7}\approx 50$

The larger earthquake had about 50 times the intensity of the smaller one.

1 oz of walnuts were mixed with 4 oz of peanuts which cost $4/oz to make mixed nuts which cost $5/oz. what is the price per oz o

Zanzabum

Call w the unknwon price of the walnuts, then:

total cost of walnuts = 1oz * w

Total cost of peanuts = 4 oz * $4/oz = $16

Total cost of nuts = 5oz * $5 /oz = $25

=> 1oz*w + $16 = $25 => w = ($25 - $16) /1oz = $9/oz

Verfify:

1oz * $9/oz + 4oz * $4/oz = $9 + $16 = $25, which is equal to 5oz * $5/oz.

Answer: $9 per oz.
