Answer:

△JKL ~ △ABC

Step-by-step explanation:

we know that

If two triangles are similar, then the ratio of its corresponding sides is proportional and its corresponding angles are congruent

In this problem

△JKL ~ △ABC

Because the ratio of its corresponding sides is proportional

Verify

$\frac{CA}{LJ}=\frac{BC}{KL}$

substitute the given values

$\frac{14}{7}=\frac{20}{10}$

$2=2$ ---> is true

The ratio of the corresponding sides is proportional

therefore

△JKL ~ △ABC

Taji has a total of 98 quarters and dimes. their value is $18.20 how many quarters does taji have?

scZoUnD [109]

Answer:

Taji has a total of 56 quarters.

Step-by-step explanation:

Let x be the number of quarters that Taji has.

Amount in terms of quarter $=0.25 \times x$

Let y be the number of dimes that Taji has.

Amount in terms of quarter $=0.10 \times y$

As per question statement:

$x + y = 98 ...... (1)$

Total amount is $18.20 as given in the question statement.

$\Rightarrow 18.20 = 0.25 \times x + 0.10 \times y\\\Rightarrow 25x + 10y = 1820 ...... (2)$

Solving equations (1) and (2):

Multiplying equation (1) by 10 and subtracting from equation (2):

$25x + 10y -10x -10y= 1820 - 980\\\Rightarrow 15x = 840\\\Rightarrow x = 56$

x is the number of quarters that Taji has.

So, Taji has a total of 56 quarters.

Queetlon 10 or 15

Marrrta [24]

Answer:

[B]

Step-by-step explanation:

Given:

People leaving the library were asked how many books they checked out that day The result are: 1,2, 3, 5, 8, 9, 10, 11, 12, 13, 14, 15, 16, 18, 20

To Find:

Which histogram correctly shows the data set?

Solution:
Since it given from the histogram:

0-5, 6-11, 12 - 17,18-23

From the result :

1,2, 3, 5, 8, 9, 10, 11, 12, 13, 14, 15, 16, 18, 20

Thus,

1,2,3,5 = 0-5

8,9,10,11 = 6-11

12,13,14,15,16 = 12-17

18,20 = 18-23

From this we can see that:

for

0 - 5 = 4

6 - 11 = 4

12 - 17 = 5

18 - 23 = 2

Hence, the answer is [B]

3/4 + 1/2 + 1/3 + 2/9 + ....... = 9/4 es verdadero oh falso y como se resuelve ?

Ahat [919]

The missing fraction is 7/9

<h3>Finding missing values in an addition equation</h3>

The given equation is:

$\frac{3}{4}+\frac{1}{2}+\frac{2}{9}+x=\frac{9}{4}$

This can be simplified as:

$\frac{27+18+8+36x}{36} =\frac{9}{4} \\\\\frac{53+36x}{36} =\frac{9}{4}$

Cross multiply

$9(36)=4(53+36x)\\\\324=212+144x\\\\144x=324-212\\\\144x=112\\\\x=\frac{112}{144} \\\\x=\frac{7}{9}$

Therefore, the missing value is $\frac{7}{9}$
