Answer:

Option 3: t=9

Step-by-step explanation:

Given: 5(t+2)-3(2t+1)=-2

Distributive Property: 5t+10-6t-3=-2

Combine like terms: -t+7=-2

Subtract 4 from both sides: -t=-9

Divide both sides by -1: t=9

So t=9

Express the ratio in lowest form:<br>1.5 kg: 350 g​
irakobra [83]

Given:

The ratio is:

1.5 kg : 350 g​

To find:

The lowest or simplest form of the given ratio.

Solution:

We know that,

1 kg = 1000 g

We have,

1.5 kg : 350 g​

It can be written as

1.5\ kg : 350\ g=\dfrac{1.5\ kg}{350\ g}

1.5\ kg : 350\ g=\dfrac{1.5\times 1000\ g}{350\ g}

1.5\ kg : 350\ g=\dfrac{1500\ g}{350\ g}

1.5\ kg : 350\ g=\dfrac{150}{35}

1.5\ kg : 350\ g=\dfrac{30}{7}

Therefore, the lowest form of the given ratio is 30:7.

These cones are similar. Find the surface
eduard

Answer:

33.3 cm²

Step-by-step explanation:

Recall: Area Scale Factor = (Linear Scale Factor)²

Area scale factor = surface area of bigger cone/surface area of smaller cone

Let the surface area of the smaller cone be represented as x

Therefore,

Area scale factor = 75/x

Linear scale factor = radius of bigger cone/radius of smaller cone = 3/2

Thus:

75/x = (3/2)²

75/x = 9/4

Cross multiply

x*9 = 75*4

9x = 300

Divide both sides by 9

x = 300/9

x = 33.3 cm² (nearest tenth)
