Solve for x. Your answer may be in decimal form. Round to the nearest tenth.
Answers
Answer:
[tex]x=54.6[/tex]
Step-by-step explanation:
Because ΔABC is similar to ΔSTU, we know that their corresponding sides are proportional. Therefore, we know that [tex]\frac{AB}{AC}=\frac{SU}{ST}[/tex]. We are given that [tex]AB=x[/tex], [tex]AC=21[/tex], [tex]SU=13[/tex], and [tex]ST=5[/tex]. After substituting the given values into the proportion and solving for [tex]x[/tex], we get:
[tex]\frac{AB}{AC}=\frac{SU}{ST}[/tex]
[tex]\frac{x}{21} =\frac{13}{5}[/tex] (Substitute given values into the proportion)
[tex]5*x=13*21[/tex] (Cross-Products Property)
[tex]5x=273[/tex] (Simplify)
[tex]\frac{5x}{5}=\frac{273}{5}[/tex] (Divide both sides of the equation by [tex]5[/tex] to get rid of [tex]x[/tex]'s coefficient)
[tex]x=54.6[/tex] (Simplify)
Hope this helps!
Answer:
x=55
Step-by-step explanation:
these are similar triangles(they have same shape and different sizes)
also two side of these triangles are equal.

The terminal side of θ passes through the point (10, 6). What is the exact value of cos θ in simplified form?
Answers
Answer:
[tex]\frac{5\sqrt{34}}{34}[/tex]
Step-by-step explanation:
The formula for cos θ is a/r. A is the first number (10) and b is the second number (6). R is the hypoteneuse which can be found through r = [tex]\sqrt{a^{2} + b^{2} }[/tex].
In the equation you'd write that as r = [tex]\sqrt{10^{2} + 6^{2}[/tex] which can be simplified to [tex]\sqrt{136[/tex].
You end up with [tex]\frac{10}{\sqrt{136} }[/tex] and you simplify this by doing [tex]\frac{10 }{\sqrt{136} } * \frac{\sqrt{136} }{\sqrt{136} }[/tex], ending with the result of [tex]\frac{5\sqrt{34}}{\sqrt{34} }[/tex].

The anwer pls:Cameron has 2 video game holder stands. Each stand has 2 rows of 20 and 2 rows of 24 games. Find the total number of video games Cameron's stands can hold.
Answers
Answer: 176
Step-by-step explanation:
GIven: In each stand,
It has 2 rows of 20 games.
It has 2 rows of 24 games.
Total number of video games in each stand = 2 x 20 + 2x 24
= 40+48
= 88
Since there are 2 identical stands,
then toral video games in 2 stands = 2 (88)= 176
Hence, the total number of video games Cameron's stands can hold= 176.

14. There are 12 marbles in a bag. Of these, Four of them are blue and the rest are green. You reach into the bag and take out two marbles without looking. What is the probability that both marbles are blue? Round to the nearest whole percent.
Answers
Answer:1/4
Step-by-step explanation: im sry if im wrong
The probability that both marbles are blue is 9 percent.
It is given that 12 marbles in a bag, four of them are blue and the rest are green.
To find the probability that both marbles are blue.
What is probability?The ratio of the number of outcomes in an exhaustive set of equally likely outcomes that produce a given event to the total number of possible outcomes.
Let both the marble be blue for event A.
P(A)=2C4/2C12 (combination formula)
=6/66
=1/11
≅0.09
=9percent.
So ,the probability that both marbles are blue is 9 percent.

Irene says the equation 9x+15=3x+15 has no solution because 9x is greater then 3x. is he right yes or no and explain why
Answers
Answer:
This equation has one solution, if x = 0
Step-by-step explanation:
Because, you subtract 15 from both sides so: 9x + 15 - 15 = 3x + 15 - 15 which equals: 9x = 3x. if x = 0 this equation is true.
Answer:
X=0
Step-by-step explanation:
If we subtract 15 from both sides, then we can see 9x=3x. If x was 0, then the equation would be 9x0=3x0. Since 0 times anything equals 0, this equation would be true resulting in 0=0.
Work out the angle of x ?
Does anyone know how to do this..
Answers
Answer:
x = 45°
Step-by-step explanation:
From the triangle given in the picture,
It's given that two sides of the triangle are equal so the triangle is an isosceles triangle.
By the property of isosceles triangle,
Opposite angles of the equal sides are equal in measure.
By triangle sum theorem,
x + x + 90° = 180°
2x + 90 = 180
2x = 180 - 90
x = [tex]\frac{90}{2}[/tex]
x = 45°

Anna earns money by walking dogs on Saturdays. Each Saturday she walks 5 dogs for 30 minutes. She charges one
customer $8 because the dog is very large. Each of the other customers pays $6. Which equation could be used to find out
how much money Anna earns each Saturday?
A)
y = 6 + 8
B)
y = 4 x 6 + 8
09
y = 4 * 6-8
D)
y = 5 x 6 + 8
Answers
Answer:
y = 4 x 6 + 8
Step-by-step explanation:
the 4 is the amount of dogs that arent big
the is 6 is the amount that she gets for walking the normal sized dogs
the 8 dollars is the amount that she gets for walking the big dog
so you would multiply 4x6 which would give you 24
then add the 8 and you will get 32
so that would mean she gets 32$ every saturday

A school receive a shipment of four boxes of paper in the school wants to split the paper equally among its three printers how much paper should go into each printer?
Answers
Answer:
[tex]\dfrac{4}{3}[/tex]
Step-by-step explanation:
Number of boxes of paper = 4
Number of printer = 3
We have to find the number of pages in each printer.
Let the number of pages in each box be 1.
Total number of pages in 4 boxes = 4
3 printer will have pages = 4
1 Printer will have pages = [tex]\dfrac{4}{3}[/tex]
Hence, pages each printer will have is equal to [tex]\dfrac{4}{3}[/tex].
