Answer:

x = 43 and y = 32

Step-by-step explanation:

x equals 43 because they are alternate interior angles

to find y first find the other missing value in the upper triangle by subtracting 180 - 75 = 105 then subtract 180 - 105 - 43 = 32 which is y

Answer:

1.3cm

Step-by-step explanation:

The scale from the actual coin to the photo is 8 mm to 2 cm In the photo,

converting 8mm to cm = 0.8 cm

using ratio and proportion,

if 2cm = 3.25 cm

then 0.8cm = ? less

if less then more devides.

thus ; (0.8cm ÷2cm ) × 3.25cm =

( 0.4) × 3.25cm = 1.3cm

therefore the distance across the actual coin is 1.3cm.

So I’m not great in math at all I spent 15 min crying because I don’t get it so anyone pls help

Yuri [45]

Answer:

Step-by-step explanation:

The area (A) of a triangle is calculated as

A = $\frac{1}{2}$ bh ( b is the base and h the perpendicular height )

Here b = 13 and h = 4 , thus

A = $\frac{1}{2}$ × 13 × 4 = $\frac{1}{2}$ × 52 = 26 units² → A

Value of P: 3/15(p+10)=-15

ArbitrLikvidat [17]

Step 1 : 1 Simplify — 5 Equation at the end of step 1 : 1 (— • (p + 10)) - -15 = 0 5 Step 2 :Equation at the end of step 2 : (p + 10) ———————— - -15 = 0 5 Step 3 :Rewriting the whole as an Equivalent Fraction :

3.1 Subtracting a whole from a fraction

Rewrite the whole as a fraction using 5 as the denominator :

-15 -15 • 5 -15 = ——— = ——————— 1 5

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

Adding fractions that have a common denominator :

3.2 Adding up the two equivalent fractions
Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

(p+10) - (-15 • 5) p + 85 —————————————————— = —————— 5 5 Equation at the end of step 3 : p + 85 —————— = 0 5 Step 4 :When a fraction equals zero : 4.1 When a fraction equals zero ...

Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.

Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.

Here's how:

p+85 ———— • 5 = 0 • 5 5

Now, on the left hand side, the 5 cancels out the denominator, while, on the right hand side, zero times anything is still zero.

The equation now takes the shape :
p+85 = 0

Solving a Single Variable Equation :

4.2 Solve : p+85 = 0

Subtract 85 from both sides of the equation :
 p = -85

One solution was found : p = -85

1. Using your straightedge, draw a reference line, if one is not provided.
2. Copy the side of the square onto the reference line, starting at a point labeled A'.
3. Construct a perpendicular at point B' to the line through ab2.
4. Place your compass point at B', and copy the side of the square onto the perpendicular b'g. Label the end of the segment copy as point C.
5. With your compass still set at a span representing AB, place the compass point at C and swing an arc to the left.
6. Holding this same span, place the compass point at A' and swing an arc intersecting with the previous arc. Label the point of intersection as D.
7. Connect points A' to D, D to C, and C to B' to form a square.

The information about the rational numbers and integers shows that the correct option is C.

<h3>How to explain the information?</h3>

It should be noted that rational numbers are numbers where we can write as a fraction of two integers. Any rational number is in the form a/b where a,b are integers and b is nonzero.

Terminating decimals can be written as a rational number. Something like 3.1 is equivalent to 31/10.

Of the four answer choices, only choice C is correct.

Choice A has the value '3' as a rational number, but it doesn't have it in the set of integers as well. So that's why choice A is incorrect.

Choice B has -3.4 in the set of integers, which is not correct. Integers do not have any decimal portion. The same applies to choice D also. We can rule choices B and D out.

Therefore, the correct option is C.
