What is the value of the expression below when x = 3?<br> 10x2 – 7x + 10

QveST [7]

Answer:

79

Step-by-step explanation:

To find the value of $10x^2 – 7x + 10$ , when x = 3, simply plug in the value of x in the expression and solve as follows:

$10(3)^2 – 7(3) + 10$

$10(9) – 21 + 10$

$90 – 21 + 10$

$79$

The value of $10x^2 – 7x + 10$ , when x = 3, is 79

Estimate 58% of 112 using benchmark percents. Explain your answer.

vitfil [10]

Answer:

64.96

Step-by-step explanation:

The most common benchmark percents are $0\% , 10\% , 25\% , 50\% , 75\%$ and $100\%$

We are given $58\%$ which is closest to $50\%$ .

Now we calculate $50\% \ of \ 112$ which is equal to $56$ .

We are left with $8\%$ more to add.

We can say $1\% \ of \ 112 \ is\ 1.12$

Therefore $8\% \ of \ 112 \ would \ be \ 1.12\times8=8.96$

Now add the two.

$56+8.96= 64.96$

Thus 64.96 is the answer.

Find the lateral area for the pyramid with the equilateral base

likoan [24]

<h3>The lateral area for the pyramid with the equilateral base is 144 square units</h3>

<em><u>Solution:</u></em>

The given pyramid has 3 lateral triangular side

The figure is attached below

Base of triangle = 12 unit

<em><u>Find the perpendicular</u></em>

By Pythagoras theorem

$hypotenuse^2 = opposite^2 + adjacent^2$

Therefore,

$opposite^2 = 10^2 - 6^2\\\\opposite^2 = 100 - 36\\\\opposite^2 = 64\\\\opposite = 8$

<em><u>Find the lateral surface area of 1 triangle</u></em>

$\text{ Area of 1 lateral triangle } = \frac{1}{2} \times opposite \times base$

$\text{ Area of 1 lateral triangle } = \frac{1}{2} \times 8 \times 12\\\\\text{ Area of 1 lateral triangle } = 48$

<em><u>Thus, lateral surface area of 3 triangle is:</u></em>

3 x 48 = 144

Thus lateral area for the pyramid with the equilateral base is 144 square units
