What must the missing length be for the two figures to be similar
Answer:
30
Step-by-step explanation:
First do 25/20 to get the proportional rate which is 1.25
then multiply 24 by 1.25 to get 30
The missing length PQ must be 30 for the two figures to be similar.
For two figures to be similar, their corresponding sides must have proportional lengths. Lets denote the two given quadrilaterals as PQRS and ABCD. To find the missing length PQ, we need to determine the proportional relationship between the corresponding sides of Quad PQRS and Quad ABCD.
The corresponding sides are:
PQ and AB
QR and BC
RS and CD
PS and AD
Since Quad PQRS ~ Quad ABCD, we can set up proportions for the corresponding sides:
[tex]\(\frac{{PQ}}{{AB}} = \frac{{QR}}{{BC}} = \frac{{RS}}{{CD}} = \frac{{PS}}{{AD}}\)[/tex]
Given:
QR = 25
RS = 25
AB = 24
BC = 20
DA = 28
Let's use the proportion [tex]\(\frac{{PQ}}{{AB}} = \frac{{QR}}{{BC}}\)[/tex] to find PQ:
[tex]\(\frac{{PQ}}{{24}} = \frac{{25}}{{20}}\)[/tex]
Cross-multiply to solve for PQ:
[tex]\(PQ \times 20 = 24 \times 25\)\\\\\(PQ = \frac{{24 \times 25}}{{20}}\)\\\\\(PQ = 30\)[/tex]
Therefore, PQ must be 30 for the two figures to be similar.

According to the synthetic division below, which of the following statements are true?
Answer:
Options (A) and (D)
Step-by-step explanation:
We can write the given division as,
[tex]\frac{2x^2+6x-8}{x+5}=2x-4+\frac{12}{x+5}[/tex]
Option (A)
When (2x² + 6x - 8) is divided (x + 5), the remainder is 12.
True.
Option (B)
When (2x² + 6x - 8) is divided (x - 5), the remainder is 12.
False.
Option (C)
When x = 5,
2x² + 6x - 8 = 12
2(5)² + 6(5) - 8 = 50 + 30 - 8
= 72
False.
Option (D)
When x = -5,
2(-5)² + 6(-5) - 8 = 50 - 30 - 8
= 12
True.
Option (E)
(x - 5) is a factor of 2x² + 6x - 8
If (x - 5) is a factor value of 2x² + 6x - 8 should be zero.
False.
Option (F)
(x + 5) is a factor of 2x² + 6x - 8
If (x + 5) is a factor then by substituting x = -5 in the expression value should be zero.
But the value is 12.
False.

9514 1404 393
Answer:
a) 18/6 = b/4 = r/5
b) b = 12, r = 15
Step-by-step explanation:
a) The proportion will simply state the fact that the ratio of shirt dimension to logo dimension is the same for all. We'll use 'b' for the bottom dimension and 'r' for the upper right dimension. Then the proportions are ...
shirt/logo = 18/6 = b/4 = r/5
__
b) In each case, multiply by the denominator to find the value of the variable.
3(4) = b = 12
3(5) = r = 15
The bottom dimension is 12 cm; the top right dimension is 15 cm.

the sum of 11 and m is greater than -23
Answer:
11 + m > -23
Step-by-step explanation:
Answer:
m > -34
Step-by-step explanation:
1 - Translate words to math
The sum of 11 and m
11 + m
is greater than -23
> -23
Therefore our inequality is;
11 + m > -23
2 - Solve it algebraicly
Although we dont use this rule here its good to know.
Unless we divide or multiply by negatives our inequality symbol stays the same. If that rule applies we flip the inequality (i.e. > to < and vice versa)
Now with that out of the way we can fully simplify our inequality as long as we know it works like an equality.
11 + m > -23
-11 -11
m > -34
So with this in mind we know our m value is greater than all numbers greater than -34 which is written as m > -34

A county has two elementary schools, both of which have an after-school program for the convenience of working parents. In school A, of the children attend the after-school program; in school of the children attend the after-school program. If school A has 600 students and school B has 900 students , then what is the fraction of elementary school students in the county who attend the after -school program ?
Answer:
8/15
Step-by-step explanation:
Given that school A has 600 students and school B has 900 students.
As in School A, 1/3 of the children attend the after-school program.
So, the number of students in school A, who attend the after-school program, n_A= 1/3 x 600 = 200.
As in School B, 2/3 of the children attend the after-school program.
So, the number of students in school B, who attend the after-school program, n_B= 2/3 x 900 = 600.
Total number of elementary school students in the county who attend the after -school program= n_A +n_B = 200 + 600 = 800.
Total number of elementary school students in the county,
N = 600+900=1500
Hence, the fraction of elementary school students in the county who attend the after-school program = 800/1500 = 8/15.

What is Trigonometry?The area of mathematics that deals with particular angles' functions and how to use those functions in calculations. There are six popular trigonometric functions for an angle. Sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant are their respective names and acronyms (csc).
Given:
sin (x-y)/ cos (x- y)
Step 2:
= sin x cos y + cos x sin y / cos x cos y - sin x sin y
Step 3:
= (sin x cos y + cos x sin y) / cos x cos y ÷ ( cos x cos y - sin x sin y ) / cos x cos y
step 4:
= sin x cos y/ cos x cos y + cos x sin y / cos x cos y ÷
(cos x cos y / cos x cos y - sin x sin y / cos x cos y)
Step 5:
= tan x + tan y / 1- tan x tan y
