Answer:

C. 78°

Step-by-step explanation:

The sum of angles in a triangle is 180°.

(7x-6)° +(4x+11)° +43° = 180°

11x +48 = 180 . . . . . divide by °, simplify

11x = 132 . . . . . . . subtract 48

x = 12 . . . . . . . divide by 11

Then the measure of angle T is ...

∠T = (7x -6)° = (7(12) -6)°

∠T = 78°

Grandma bakes the world's best and favorite cookies. If grandma's cookies have a half life of 2 hours and she bakes 3 dozen cook

Alchen [17]

Answer:

The time that pass until only two cookies left is 1.89 hour

Step-by-step explanation:

Given as :

The number of cookies bakes in 2 hours = 3 dozen

∵ 1 dozen = 12 piece

So, In 3 dozen = 12 × 3 = 36 cookies

The Time required to bake 36 cookies = 2 hours

Now, Let The time required to bake 2 cookies = x hour

So, According to question

∵ The time required to bake 36 cookies = 2 hours

So, the time required to bake 1 cookies = $\frac{2}{36}$ = $\frac{1}{18}$ hour

∴The time required to bake 34 cookies = $\frac{1}{18}$ × 34

I.e The time required to bake 34 cookies = $\frac{34}{18}$ hour = 1.89 hour

Or, the time taken is 1.89 hours

Hence The time that pass until only two cookies left is 1.89 hour Answer

Which graph represents the linear function below?

Luba_88 [7]

Answer:

The correct option is C.

Step-by-step explanation:

The given function is

$y-4=\frac{4}{3}(x-2)$ ..... (1)

The point slope form of a linear function is

$y-y_1=m(x-x_1)$ ..... (2)

Where, m is slope and the graph passing through the point $(x_1,y_1)$ .

From (1) and (2), we get

$m=\frac{4}{3},x_1=2,y_1=4$

It means the slope of the line is positive and the graph passing though the point (2,4).

Put x=0 in the given function, to find the y-intercept.

$y-4=\frac{4}{3}(0-2)$

$y-4=\frac{-8}{3}$

$y=\frac{-8}{3}+4$

$y=\frac{-8+12}{3}$

$y=1.333$

The y-intercept is 1.333.

Put y=0 in the given function, to find the x-intercept.

$0-4=\frac{4}{3}(x-2)$

$-12=4x-8$

$-4=4x$

$x=-1$

The x-intercept is -1.

Therefore option C is correct.

2.) I am a two-digit number that can be referred to as a perfect square. The sum of my two digits is 10. What number am I?

Scorpion4ik [409]

Answer: 64

Step-by-step explanation:

By definition, a perfect square is the square of a whole number.

The information given in the problem that you must keep on mind is:

- The number has two digits.

- The number is a perfect square ( Is obtained by squaring a whole number).

- The sum of its two digits is 10.

The number 64 is formed by the digit 6 and the digit 4. The sum of both digits is:

$6+4=10$

The number 64 can be written as:

$64=8*8=8^2$

Then, it is perfect square.

Find the shaded area, screenshot provided please help I have an online exam, and I only have 10 minutes remaining

NARA [144]

Answer:

157.1

Step-by-step explanation:

If you split the blue shape like in the picture, it shows that there is 1 large semicircle and 2 smaller ones.

The area of a semicircle is (pi×radius²)÷2

First, you would find out the area of the large semicircle by substituting in the numbers:

(3.142×10²)÷2=157.1

Then you would find out the area of the smaller semicircle:

The diameter of the semicircle is 10 so to find the radius you would half it.

(3.142×5²)÷2=39.275

To find the area of the whole shape, you would have to take away 39.275 and then add it back on so the answer would be 157.1

Hope this helps :)
