Answer:

4 tiles

Step-by-step explanation:

If the width is 84 cm, let's take a 84cm lengthed tile.

in the remaining part we get 112-84=28 cm

let's check whether 84÷ 28 is a whole number. if it's a whole number we can keep the n number of 28 cm length tile

84÷28=3

luckily we dont need to think a lot. just put 3, 28 cm tile in the balance part .

she only needs 4 tiles to fill the table

For the triangles to be similar by the sss similarity theorem what must be the value of y 18 20 24 26

Ludmilka [50]

Answer:

Step-by-step explanation:

The picture of the question in the attached figure

we know that

If the figures are similar by SSS Similarity Theorem, then the ratio of its corresponding sides must be proportional

$\frac{PQ}{AB}=\frac{PR}{AC}$

substitute the given values

$\frac{y}{10}=\frac{28}{14}$

solve for y

$y=10(2)\\y=20\ units$

Answer:

(a) Percentage of girls = 55 $\frac{5}{7}$

(b) Percentage of boys = 44 $\frac{2}{7}$

Step-by-step explanation:

To find percentage, we multiply the fraction out of the total by 100%.

Percentage of girls = $\frac{780}{1400}$ × 100%

= 55 $\frac{5}{7}$

Percentage of boys = $\frac{1400-780}{1400}$ × 100%

= 44 $\frac{2}{7}$

I don’t understand how to proof Cpctc or answer the questions

n200080 [17]

I think that first you need to understand what CPCTC is used for.

Let's start with the definition of congruent triangles.

Definition of congruent triangles
Two triangles are congruent if each side of one triangle is congruent to a corresponding side of the other triangle and each angle of one triangle is congruent to a corresponding angle of the other triangle.

A definition works two ways.
1) If you are told the sides and angles of one triangle are congruent to the corresponding sides and angle of a second triangle, then you can conclude the triangles are congruent.
2) If you are told the triangles are congruent, then you can conclude 6 statements of congruence, 3 for sides and 3 for angles.

Now let's see what CPCTC is and how it works.
CPCTC stands for "corresponding parts of congruent triangles are congruent."
The way it works is this. You can prove triangles congruent by knowing fewer that 6 statements of congruence. You can use ASA, SAS, AAS, SSS, etc. Once you prove two triangles congruent, then by the definition of congruent triangles, there are 6 congruent statements. That is where CPCTC comes in. Once you prove the triangles congruent, then you can conclude two corresponding sides or two corresponding angles are congruent by CPCTC. These two corresponding parts were not involved in proving the triangles congruent.

Problem 1.

Statements                                        Reasons
1. Seg. AD perp. seg. BC               1. Given
2. <ADB & <ADC are right angles     2. Def. of perp. lines
3. <ADB is congr. <ADC                 3. All right angles are congruent
4. Seg. BD is congr. seg CD           4. Given
5. Seg. AD is congr. seg. AD        5. Congruence of segments is reflexive
6. Tr. ABD is congr. tr. ACD           6. SAS
7. Seg. AB is congr. seg. AC        7. CPCTC
