Answer:

7. option D

8. option D

Step-by-step explanation:

7.  we can assume the height of the radio tower to be x. We're given with its shadow,the height of the person and also their shadow. Since we have 3 known values and an unknown, we can make a proportion comparing the tower's height to the height of the person.

∴ 6/10 = x/ 400

⇒ x= (6 * 400)/10 = 240 feet.

8.  The question is similar to the above question where again we have 3 knowns and one unknown. Let us assume the length to be x. We'll again compare the length of the two photographs and make it as a proportion.

∴ 4/6 = x/10

⇒ x = (4 * 10)/6 = 6.7 in

Hope that answers your questions!

In a right triangle, if a = 8 and c = 17, what is the correct setup to find the value of b?
salantis [7]

Answer:

b =15

Step-by-step explanation:

We can use Pythagoras theorem to find b:

a^{2}+b^{2} = c^{2}

8^{2} + b^{2} = 17^{2}

64 + b^{2} = 289

64 + 225 = 289

64 + 15^{2} = 289

b = 15

hope this helps :) and sorry if not right

gizmo_the_mogwai [7]
Definition of additive inverse.- If two numbers are added together and the sum is zero, they are the additive inverse of each other. 


<span>......................................... IF A + B = 0 , they are the additive inverse of each other. 
</span>

<span>Multiplicative Inverse.- If two numbers are multiplied together and the product is one. They are the multiplicative inverse of each other, also called reciprocal. </span>

<span>......................................... A.B = 1 , they are the multiplicative inverse of each other. 
</span>

<span>Example of: </span>

<span>Additive inverses :................ 5 + ( - 5 ) = 0 </span>

<span>Multiplicative inverses...........5 x 1/5 = 1 </span>

QUESTION 8. An unknown number is added to 8. The sum is
Rudik [331]

Answer:

82

Step-by-step explanation:

Let the unknown number be x

If an unknown number is added to 8, this is expressed as;

8 + x

<em>If The sum is  then divided by 9 to give the answer 10, then;</em>

<em>(8+x)/9 = 10</em>

<em>Cross multiply</em>

<em>8 + x = 9 * 10</em>

<em>8 + x = 90</em>

<em>x = 90 - 8</em>

<em>x = 82</em>

Hence the unknown number is 82
