Answer: [tex]\dfrac{4}{8}=\dfrac{y}{14}[/tex]
Step-by-step explanation:
in the given figure, we can observe that both triangles are similar since they have two equal angles of 100° and 60° .[By AA similarity criteria]
Also, the corresponding sides of similar triangles are proportional.
As side with measure 8 in bigger triangle corresponds side with measure 4 on the smaller triangle. [shortest side]
Similarly, side with measure 14 in bigger triangle corresponds side with measure y on the smaller triangle. [longest side]
Using proportionality, we have
[tex]\dfrac{4}{8}=\dfrac{y}{14}[/tex]
Hence, the proportion can be used to find the value of y is [tex]\dfrac{4}{8}=\dfrac{y}{14}[/tex].
According to AA similarity criterion-, if any two angles of one triangle are equal to any two angles of the other, then the two triangles will be similar.work out (8x10^-3) x (2x10^-4)
Answer:
[tex]1.6 \times 10^{-6}[/tex]
Step-by-step explanation:
[tex](8 \times 10^{-3}) \times (2 \times 10^{-4})[/tex]
[tex]8 \times 2 \times 10^{-3} \times 10^{-4}[/tex]
[tex]16 \times 10^{-3+(-4)}[/tex]
[tex]16 \times 10^{-3-4}[/tex]
[tex]16 \times 10^{-7}[/tex]
[tex]1.6 \times 10^{-6}[/tex]
Answer:
(8 × 10^-3)× ( 2× 10 ^-4)
reorder the terms
You will get
(8 × 2) ( 10^ -3 × 10^-4)
Multiply
16 ( 10^ -3 × 10^-4)
Use the rules of indices
a^ b × a^ c = a^b+c
16(10^-3-4)
16(10^-7)
= 16 × 10^-7 or 1.6 × 10^-6 or 0.0000016

Please explain how you get your answer, ty
Answer:
y=2
x=2
y=x2+2
y= lx+2l
Step-by-step explanation:
This is because these are the simplest forms of the equation. seeing as a function is f(x) (which is the same as y) when an equation is equal to a single variable, it is "solved" for hat variable and therefore best represents the equation of the function :)

can 20 degrees 60 degrees and 100 degrees be a triangle
Answer: Yes
Step-by-step explanation: The area of a triangle equals 180°
100+60+20=180
Answer: Yes
Explanation: The sum of the measures of the angles is always 180°
This idea is known as the (Triangle Sum Theorem).
Since 20 + 60 + 100 is equal to 180, we know
that these measures can form a triangle.

affects the maximum speed of a marble being rolled down the ramp. To
study this, she compares the maximum speed of a marble rolled down
ramps with different surfaces. She rolls the same marble down each type
of ramp 10 times. What type of study is this? *
O Survey
Observational study
O Experimental study
Answer:
The correct option is;
Experimental study
Step-by-step explanation:
We note that an observational study is one where the person who carries out the study only puts together data or observes the effect of a factor, an intervention or a test and comes to conclusion based on what is observed without trying to control the variables while an experiment involves the application of an intervention to the group and taking down the effects.
The conditions of the study is directly under the influence of the researcher in an experiment such that the cause and effect relationship of an event can clearly be proved
Therefore, Jada is performing an experimental study.

In right triangle ABC, ∠C is a right angle, m∠A=52∘, AC=10.01, and AB=c.
sin52∘≈0.788
cos52∘≈0.616
tan52∘≈1.280
What is the measurement of AB?
In right triangle GHI, ∠H is a right angle, m∠I=42∘, and GH=11.
sin42∘≈0.67
cos42∘≈0.74
tan42∘≈0.90
What is the measurement of HI?
9514 1404 393
Answer:
AB = 16.25HI = 12.22Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you of the relevant relationships.
__
1. Cos = Adjacent/Hypotenuse
cos(52°) = AC/AB
AB = AC/cos(52°) = 10.01/0.616
AB = 16.25
__
2. Tan = Opposite/Adjacent
tan(42°) = GH/HI = 11/HI
HI = 11/tan(42°) = 11/0.90
HI ≈ 12.22

Step-by-step explanation:
Using the experimental probability, first we have to find total amount paint then to find the amount of good quality forever paint we have to subtract the amounts of other paints from total amount.
Let x represents the amount of good quality forever paint sold.
Total amount of paint [tex]=48+45+35+39+33+x=200+x[/tex] ...(i)
Experimental probability of paint sold will be better quality durable paint is
[tex]P=\dfrac{\text{Amount of better quality durable paint}}{\text{Amount of total paint}}[/tex]
[tex]P=\dfrac{45}{\text{Amount of total paint}}[/tex]
It is given that experimental probability of paint sold will be better quality durable paint is [tex]\frac{9}{50}.[/tex]
[tex]\frac{9}{50}=\dfrac{45}{\text{Amount of total paint}}[/tex]
[tex]\text{Amount of total paint}=\dfrac{45\times 50}{9}[/tex]
[tex]\text{Amount of total paint}=250[/tex] ...(ii)
From (i) and (ii), we get
[tex]200+x=250[/tex]
[tex]x=250-200[/tex]
[tex]x=50[/tex]
Therefore, 50 gallons good quality forever paint is sold.

six copies of the sum of nine fifths and three.
Answer:
9/5+3/1
24/5 24/5 24/5 24/5 24/5 24/5
i think copies is a multiplication and sum is to add together so
6x(9/5+3)
9/5 is 1 whole and 4/5. 1 whole plus 3 wholes is 4 Wholes so it is 4 wholes and 4/5 which is 24/5.
6x24/5 is (6x24 is 144) so its 144/5 so its 28 wholes and 4/5.
The graph below shows the number of pages Matthew read in x hours. Find the slope of the line. Explain what the slope represents.
Answer: The slope represents the RATE at which Matthew read pages in x hours.
Step-by-step explanation:

PLS I NEED HELP...THE PICTURES ARE IN ORDER (13 POINTS ) Question 1 Solve the following equation. Explain or show your reasoning. ---------------------------------------------------------------------------------------- Question 2 Solve the following equation. Explain or show your reasoning. ------------------------------------------------------------------------------------------ Clare was solving an equation, but when she checked her answer she saw her solution was incorrect. She knows she made a mistake, but she can’t find it. Where is Clare's mistake and what is the solution to the equation?
Answer:
1 . x = 9,
2 . n = 4,
3 . Clare made an error in the 2nd step; Correct answer is y = - 65 / 11
Step-by-step explanation:
1 .
[tex]2 * ( x + 5 ) = 3x + 1 - Apply Distributive Property,\\\\2x + 10 = 3x + 1 - Subtract 2x from Either Side,\\10 = x + 1 - Subtract 1 from Either Side,\\\\x = 9,\\Conclusion; x = 9[/tex]
2 .
[tex]3 * ( n + 2 ) = 9 * ( 6 - n ) - Apply Distributive Property,\\\\3n + 6 = 54 - 9n - Add ( 9n ) on Either Side,\\12n + 6 = 54 - Subtract 6 from Either Side,\\\\12n = 48 - Divide Either Side by 12,\\n = 4,\\\\Conclusion; n = 4[/tex]
3 . Clare made an error in the second step ( 72 + 24y = 4y - 5 - 9y ) and to derive the correct solution, see the following steps below;
[tex]12 * ( 5 + 2y ) = 4y - ( 5 - 9y ),\\60 + 24y = 4y - 5 + 9y,\\65 + 24y = 4y + 9y,\\65 + 24y = 13y,\\\\65 = - 11y,\\y = - 65 / 11\\\\Conclusion; y = - 65 / 11[/tex]
Solve for x in the triangle. Round your answer to the nearest tenth.
Answer:
x = 6.9
Step-by-step explanation:
We're going to use SOH CAH TOA.
If we look at the angle (58°), and see what the relevant sides of the triangle are, we can see that the hypotenuse (our known side) is the H (hypotenuse), and the side labelled 'x' (our unknown side) is the A (adjacent).
According to SOH CAH TOA, we'll use cos (C), since we're working with the adjacent and the hypotenuse.
The equation for CAH is cos (Ф°) = A/H
In this case, Ф = 58°, A = x, and H = 13
So cos (58°) = x/13
Solve for x by multiplying both sides by 13 and using your calculator to evaluate.
13 cos (58°) = x
x = 6.88895
To the nearest tenth, x = 6.9
