Answer:

$\sf{ii) \: \: 23}$

Step-by-step explanation:

Use PEMDAS rule:

P = Parentheses

E = Exponents

M = Multiplication

D = Division

A = Addition

S = Subtraction

Now, let's solve:

i ) $\sf{4 \div 2 + 5 - 3}$

$\sf{ = 2 + 5 - 3}$

$\sf{ = 7 - 3}$

$\sf{ = 4}$

ii) $3 + 5 \times 8 \div 2$

$\sf{ =3 + 40 \div 2}$

$\sf{ = 3 + 20}$

$\sf{ = 23}$

Hope I helped!

Best regards!!

Choose the congruence theorem that you would use to prove the triangles congruent.

Elena L [17]

Answer:

SAS

Explanation:

Before solving the problem, let's define each of the given theorems:

1- SSS (side-side-side): This theorem is valid when the three sides of the first triangle are congruent to the corresponding three sides in the second triangle

2- SAS (side-angle-side): This theorem is valid when two sides and the included angle between them in the first triangle are congruent to the corresponding two sides and the included angle between them in the second triangle

3- ASA (angle-side-angle): This theorem is valid when two angles and the included side between them in the first triangle are congruent to the corresponding two angles and the included side between them in the second triangle

4- AAS (angle-angle-side): This theorem is valid when two angles and a side that is not included between them in the first triangle are congruent to the corresponding two angles and a side that is not included between them in the second triangle

Now, let's check the given triangles:

We can note that the two sides and the included angle between them in the first triangle are congruent to the corresponding two sides and the included angle between them in the second triangle

This means that the two triangles are congruent by SAS theorem

Hope this helps :)

A silo is in the shape of a cone. The silo is 7 meters tall, and its base has a radius of 1.5 meters. Rice costs 204$ per cubic

olganol [36]

Answer:

$3364.65

Step-by-step explanation:

The volume of the cone is given by the formula ...

V = (1/3)πr²h

Filling in the given numbers, we find the volume to be ...

V = (1/3)π(1.5 m)²(7 m) = 5.25π m³ ≈ 16.49336 m³

The cost of the rice will be the product of this volume and the price per cubic meter:
