Length of IG is 16 units.

Step-by-step explanation:

Given:

ΔGHI

∠I ≅ ∠H

GH = 16

HI = 5

To Find:

IG = ?

Solution:

In ΔGHI

∠I ≅ ∠H          ..............Given

Base angles are equal.

∴  ΔGHI is an Isosceles Triangle  

∴ GH ≅ IG  .............Property of an Isosceles Triangle

But GH = 16    ...Given

∴ IG = 16 .........Transitive Property

Therefore,

Length of IG is 16 units.

Use the grouping method to factor this polynomial x^3+2x^2+12x+24
azamat

Answer:

We can group x³ and 2x², their GCF is x² so it becomes x²(x + 2). 12x + 24 has a GCF of 12 so it becomes 12(x + 2). Since both terms have the (x + 2) factor, the answer is (x + 2)(x² + 12).

Mrs. Terrace cut a small birthday cake into 6 equal pieces for 6 children. One child was not hungry, so she gave the birthday bo
ELEN [110]

Missing part of question:

Draw a tape diagram to show how much cake each of the five children received.

Answer:

See attachment

Step-by-step explanation:

Given

Equal\ Pieces = 6

Children = 5

Required

Tape diagram to represent the scenario

Because one child is not hungry, the number of children to share the cake becomes 6.

So, first we calculate the share of each child.

Share = \frac{Pieces}{Children}

Share = \frac{6}{5}

Share = 1.2

See attachment for tape diagram

The tape diagram implies that:

5 * 1.2 = 6

or

\frac{6}{1.2} = 5

or

\frac{6}{5} = 1.2

How do i do precent to fraction
Arisa [49]
To change a fraction to a percent, treat it like a division problem. For example, to make 1/4 a percent, divide the numerator by the denominator. 1 ÷ 4 = 0.25.

Next, move the decimal point two places to the right. That changed 0.25 to 25, and just add the percent symbol. 25%

AND BAM! You've got yourself a fraction changed to a percent. 1/4 = 25%
