The measure of two complementary angles are (4x + 3)° and (x + 4)°. What is the measure of the larger angle?
Aleksandr-060686 [28]

Answer:

69.4 degrees.

Step-by-step explanation:

Complementary angles add up to 90 degrees so we have the equation:

4x + 3 + x + 4 = 90

5x + 7 = 90

5x = 83

x = 16.6

The larger angle = 4x + 3

= 4(16.6) + 3

= 69.4 degrees (answer).

The y-intercept of the line whose equation is 3x + 2y = 7 A)-3/2 B)7/3 C)7/2
sp2606 [1]

Answer:

C

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Rearrange 3x + 2y = 7 into this form

Subtract 3x from both sides

2y = - 3x + 7 ( divide all terms by 2 )

y = - \frac{3}{2} x + \frac{7}{2} ← in slope- intercept form

with y- intercept c = \frac{7}{2} → C

Helppppp! please show your work!
Shtirlitz [24]

Answer:

90 - 37 will give a solid 53

Step-by-step explanation:

the two sums of A to C to C to B so 22.9(C, B) and 14.1 (A, C)

and know that this angle is 90 degrees, my guess would be to subtract the to given numbers with degrees to earn the sum so 22.9 + 14.1 equals 37

now we add angle degrees and sum and subtract one another,

90 - 37

A label is placed around the juice box below, not including the bases. Determine the surface area of the label
nasty-shy [4]

Answer:

3 In²

Step-by-step explanation:

Talking about surface area, the total area of an object is taken into consideration.

NB: Kindly check the attached picture for the diagram of the 3D object.

In this question, the surface area has to be determined and we will have to take into consideration all the area of the 3D object given in the question.

Surface Area = 6 × k².

Surface area = 6 × ( 1.8 × 1.8) cm².

Surface Area = 19.44 cm².

The next thing to do here is to convert the cm² to in². Therefore, 19.44 cm² ------>  x in².

19.44 × 0.155 in² = 3 in².

Which of the following equations is not a linear equation?
salantis [7]

Answer:

D.

Step-by-step explanation:

All other equations have x or y to the power of one so they are linear. D. has x or y to the power of two, so it's not linear. Quadratics and any variable to the power of 2 and above is not linear (numbers on their own are also always linear, so ignore any powers on them)
