The two on the right

in geometry, for (in this case) triangles to be congruent they must be the same size, corresponding angle measures, and side lengths.

the little ticks on lines and angles are used to show congruence. For instance, if two lines both have two tick marks that means they are congruent or if an two angles each had one tick then it is saying they are congruent.

so for the top right:
line UV = line XY (they’re both 6.5)
line TU = line WX (they’re both 3)
line TV = line WY (they’re both 7)
so all the proper side lengths are congruent

angle VTU = angle YWX (they both have one tick mark to show congruence)
angle TUV = angle WXY (they both have three tick marks to show congruence)
angle UVT = angle XYW (they both have two tick marks to show congruence)
so all the proper angle measurements are congruent

therefore triangle TVU is congruent to triangle WYX

For the bottom right triangles:
line EF = line QR (they both have two tick marks to show congruence)
line DE = line PQ (they both have one tick mark to show congruence)
line DF = line PR (they both have three tick marks to show congruence)
so the proper side lengths are congruent

angle DEF = angle PQR (as it is given they are both 90°)
angle EFD = angle QRP (they both have two tick marks to show congruence)
angle FDE = angle RPQ (they both have one tick mark to show congruence)
so all the proper angle measurements are congruent

therefore triangle DFE is congruent to triangle PRQ

(triangle PRQ is just rotated)

hope this helps :)

From Andys house to Billys hometown you can travel by 3 roads. And to get from Billys hometown to Willies's house you can travel
Rom4ik [11]

Andy to get to Willie's house = 15 ways

Andy to get to Willie's house = 45 ways

<h3>How to determine the ways</h3>

From the information given, we have that from

Andy's house to Billy's  hometown = 3 roads

Billy's hometown to Willies house = 5 ways

To travel from Andy's house to Willies house, we should multiply the number of ways

= 3 × 5

= 15 ways

Dan's ranch to Andy's house = 1 road

To Willie's house = 2 roads

For Andy to get to Willie's house, we have;

= 3 × 15

= 45 ways

Find the area of the irregular shape. Round to the nearest tenth.
svp [43]
Given: 
Irregular Shape: 
Semi-circle and rectangle:

Area of a rectangle = l * w
Area of a semi-circle = (π r²)/2

Area of rectangle = 8 cm * 5 cm = 40cm²
Area of a semi-circle = (3.14 (4²))/2 = (3.14*16)/2 = 50.24/2 = 25.12cm²
4² is taken from diameter of 8cm divided by 2 to get the radius.

Total area = 40 cm² + 25.12 cm² = 65.12 cm²

Help please if anyone knows
larisa86 [58]
<u>Part A
</u>
<u />To estimate this, we should first look at our fractions and see if they can be combined to form a whole number. In this case, \frac{3}{5} and \frac{2}{3} equal approximately 1. We can add this "1" to the other to full gallons to estimate that the painter needs about 3 gallons.

<u>Part B
</u>
<u /><u />To find the exact amount, we should first change the mixed numbers to improper fractions. We do this by multiplying the denominator by the whole number, adding the numerator, and placing that value over the denominator.

1 \frac{3}{5} \\ \\  (5*1)+3 =8 \\  \\  \frac{8}{5}  \\  \\  \\ \\  1 \frac{2}{3} \\  \\ (3*1)+2=5 \\  \\  \frac{5}{3}  &#10;

Now, we need to find the least common denominator. This is the lowest value that both denominators will divide evenly into. In this case, that number is 15.

Next, we should multiply both fractions so that the denominator is that number. Remember that we must also multiply the numerator for the fraction to remain equivalent to its original value.

\frac{8}{5} *3 =   \frac{24}{15} \\  \\  \frac{5}{3} *5 =  \frac{25}{15}

Now, we can simply add our numerators.

25+24=49

We know that he needs \frac{49}{15} gallons of paint, but this is not in the most simplified format. To simplify, we need to turn our improper fraction back to a mixed number. To do this, we need to divide our numerator by the denominator to create our whole number, and the remainder becomes our new numerator.

\frac{49}{15} \\  \\ 49 / 15 = 3(Remainder: 4) \\  \\  3\frac{4}{15}

Using that logic, we can see that the painter needs exactly 3 \frac{4}{15} gallons of paint.

Which expression is equivalent
NemiM [27]
Answer:
6(3) - 4 + (3)^2

Explanation:
We will do this on two steps:
1- get g(x)-f(x)
2- substitute with x = 3

Step 1:
f(x) = 4-x^2
g(x) 6x
g(x) - f(x) = 6x - (4 - x^2)
               = 6x - 4 + x^2

Step 2:
Substitute with x = 3 as follows:
g(x) - f(x) at x = 3 is:
6(3) - 4 + (3)^2

Hope this helps :)
