Answer:

  45°

Step-by-step explanation:

The acute angles of a right triangle are complementary. The base angles of an isosceles triangle are congruent. If x is the measure of the base angles, this requires ...

  x = 90-x . . . . . the base angle is congruent to the other base angle

  2x = 90 . . . . . add x

  x = 90/2 = 45 . . . . divide by 2

The measure of a base angle of an isosceles right triangle is 45°.

Answer:

y = -1.2x + 30

x = 22

x = 15

Step-by-step explanation:

Part A

Initially, Devin has $30.  Then every time he rides the bus, $1.20 is taken away:  y = 30 - 1.2x

Therefore, in slope-intercept form:  y = -1.2x + 30

If he has $3.60 on his card, then y = 3.60, so substitute this into the above equation and solve for x:

                                                  3.60 = -1.2x + 30

subtract 30 from both sides:  -26.4 = -1.2x

divide both sides by -1.2:             22 = x

Therefore Devin has ridden the bus 22 times if he has $3.60 on his card.

Part B

Rebecca:  y = -1.4x + 33

To determine how many rides on the bus Devin and Rebecca would need to take to have the same amount of value of their bus card, simply equate the equations and solve for x:

                                          Rebecca = Devin

                                                       y = y

                                         -1.4x + 33 = 30 - 1.2x

subtract 33 from both sides:   -1.4x = -3 - 1.2x

Add 1.2x to both sides:           -0.2x = -3

Divide both sides by -0.2:             x = 15

Therefore, Devin and Rebecca would both have to take 15 rides on the bus to have the same amount of value of their bus card.

Answer:

Volume = 3 cm^3

Step-by-step explanation:

The area of the front face is equal to the sum of three squares, each square has a side equal to 1 cm

Total frontal area = (1×1) ×3faces= 3 cm^2

the volume equal to frontal area multiplied by the depth which is equal to 1 cm

Volume=3×1= 3 cm^3

Answer: Mr. Jenkins would use 'mean'.

Step-by-step explanation:

Rather than use either median or mode, he would use mean. Mean is a statistical average of numbers. It would be best to brag about the total weight that he has lost rather than using the half-way point or the most frequent appearing number in the data.

Answer:

25 tennis balls

Step-by-step explanation:

20x5= 100

5x5=25

there are 25 tennis balls in the bag

-3/5 × 3/7 + 4/5 – 3/7 × 1/10

(-3) × 3 ÷ 5(7) + 4/5 – 3 × 1 ÷ 7(10)

-9/35 + 4/5 – 3/70

-9/35 – 3/70 + 4/5

-9 × 2/35 × 2 – 3/70 + 4/5

-18 – 3/70 + 4/5

-21/70 + 4/5

-3/10 + 4/5

(-3)(5) + (10)(4) ÷ (10)(5)

-15 + 40/50

25/50 = 1/2

Thus, The answer is 1/2

The interceps for x and y is in the pic

Answer:

n = 30

Step-by-step explanation:

Step 1: Subtract 7 from both sides.

Step 2: Multiply both sides by 10.

Step 3: Check if solution is correct.

Therefore, n = 30.

Step-by-step explanation:

the slope is the ratio "y coordinate change / x coordinate change" when going from one point on the line to another.

so, for example, when using the first 2 points (0, -5) and (1, -3) we see

x changes by +1 (from 0 to 1)

y changes by +2 (from -5 to -3).

so, the slope is +2/+1 = 2

the y-intercept is the y value when x=0. so in this case -5.

this is because it identifies the point where the line intercepts the y-axis (which is the reason why x=0).

the intercept point is then (0, -5).

Transformation involves changing the coordinates of a point

The coordinates of the image of P is (9,13)

The coordinate of P is given as:

P = (-13,9)

The rule of reflecting the point over the line y = -x is represented as:

[tex](x,y) \to (y,-x)[/tex]

So, we have:

[tex](-13,9) \to (9,13)[/tex]

This means that:

[tex]P' = (9,13)[/tex]

Hence, the coordinates of the image of P is (9,13)

Answer:

300+0.75x=y

Step-by-step explanation:

x(the number of large coffes ordered)

y(the total donation)

Answer:

y=0.75x+300

Step-by-step explanation:

So for this problem, I'm going to put it in slope-intercept form (only because it makes the most sense to me, plus if you need to graph it, this will be helpful)

So Jan is donating $300 first. So whatever you need to do, you need to add 300 afterwards to account for that donation. But then, Jan is going to donate $0.75 for every large coffee ordered. This is means it is a dependent variable. The amount is dependent on how many large coffees ordered.

Say, for example, there were 15 large coffees ordered. You should multiply 0.75*15, which will give you a product of 11.25. So for all the coffees ordered, Jan will donate a total of $11.25 (which isn't a lot, but that's okay). But that isn't ALL the money that Jan donated because, as stated before, Jan is going to donate $300 regardless of how many coffees ordered. So the total amount of money donated is $311.25

Hope this helps!

Answer:  

30 + 18x = 6(5+3x)

Step-by-step explanation:

for this all you have to do is distribute the 6 by doing 6 x  5 = 30 and  

6 x 3 = 13 and then you just have to add them together to get

30 + 18x = 30 +18x

The fourth step is incorrect.

Polynomial is an algebraic expression that consists of variables and coefficients. Variable are called unknown. We can apply arithmetic operations such as addition, subtraction, etc. But not divisible by variable.

Given

x² + 4x -12 is a polynomial.

              x² + 4x - 12

Step 1.    x² + 6x - 2x -12

Step 2.  (x² + 6x) - (2x + 12)

Step 3.   x(x + 6) - 2 (x + 6)

Answer:

cosθ = ( √4 - a² ) ÷ 2

Explanation:

sinθ = a/2

according to sincostan rule:

sinθ = opposite/ hypotenuse

cosθ = adjacent/ hypotenuse

so here opposite is a and hypotenuse is 2

adjacent² + opposite² = hypotenuse²

adjacent² + a² = 2²

adjacent = √4 - a²

we found our adjacent.

so cosθ = adjacent/ hypotenuse

             =  ( √4 - a² ) / 2

so cosθ = [tex]\frac{ \sqrt{4 - a^{2}} }{2}[/tex]
