For ΔABC, ∠A = 8x - 10, ∠B = 10x - 40, and ∠C = 3x + 20. If ΔABC undergoes a dilation by a scale factor of 1 2 to create ΔA'B'C'

STALIN [3.7K]

If the triangles ABC and A'B'C' are similar, then
angle A = angle A'
8x-10 = 6x+10
8x-6x = 10+10
2x = 20
x = 20/2
x = 10

So angle A is
angle A = 8x-10
angle A = 8*10-10
angle A = 80-10
angle A = 70
making that the measure of angle A' as well

This is why the answer is choice A

Complete the area model representing the polynomial x2-11x+28 what is the factored form of the polynomial use the model to rewri

Tpy6a [65]

Answer:

The factored form of the polynomial use the model to rewrite the expression is (X-7)(X-4)

Step-by-step explanation:

given the polynomial $x^{2}$ -11x+28

=> the value of all three parameters in the function are;

a: 1

b: -11

c: 28

=> the two number that has sum is = b= 11 and product is = c = 28 are: 4 and 7

Hence, the factored form of the polynomial use the model to rewrite the expression is (X-7)(X-4)

An advertising flyer shows address labels as 4.3 cm by 1.2 cm. The ratio of the flyer label to the actual label is 2:3. What are

arlik [135]

Answer:

6.45 cm by 1.8 cm

Step-by-step explanation:

Ratio of label to actual measurement ; 2 : 3

For a flyer label size of 4.3

Actual label size equals :

(Flyer ratio / total ratio) * total size = flyer size

2/5 * x = 4.3

2x / 5 = 4.3

2x = 21.5

x = 21.5 / 2

x = 10.75

Actual size =. 10.75 - 4.3 = 6.45 cm

2/5 * x = 1.2

2x / 5 = 1.2

2x = 6

x = 6 / 2

x = 3

Actual size = 3 - 1.2 = 1.8 cm

6.45 cm by 1.8 cm

there are 40 students in a calculus class. 24 of the students are female and the rest are male. what percent of the class are fe

Lina20 [59]

Answer:

60%

Step-by-step explanation:

Create the fraction of female students to total students, then multiply this fraction by 100%

percent female students = $\frac{24}{40}$ × 100% = 60%
