Answer:

-4 .

Step-by-step explanation:

Given : $\sqrt{-16}$ .

To find : Find the value .

Solution : We have given $\sqrt{-16}$ .

We can write the $\sqrt{-16}$ = $\sqrt{- 4 * 4}$ .

$\sqrt{-16}$ = -4 .

By the radical rule : $\sqrt{-a *a} =-a$ .

Here, a = 4.

So, $\sqrt{-16}$ = -4 .

Therefore, -4 .

Find the measure of the angle

zheka24 [161]

Answer:

Step-by-step explanation:

The triangle shown is an isoceles triangle. This means that there are two congruent base angles and a vertex angle. In this case, angle X and angle Y are the base angles, so we can set up an equation to first find the value of t.

5t - 13 = 3t + 3

2t - 13 = 3 (Subtract 3t from both sides)

2t = 16 (Add 13 to both sides)

t = 8 (Divide both sides by 2)

Now that we have the value of t, we can plug it back in to the expression for angle X to find its measure.

5(8) - 13

40 - 13

So, the measure of angle X is 27

What are the dimensions of the tabletop with the

DIA [1.3K]

Answer:

Dimensions of the tabletop is 2.8 cm × 2.8 cm.

Step-by-step explanation:

From the picture attached,

ABCD is a tabletop with leaves AEG, BEF, CFH and GDH.

Dimensions of the tabletop ABCD,

Length = AB

Width = BC

Coordinates of A → (1, 3)

Coordinates of B → (3, 5)

Coordinates of C → (5, 3)

Coordinates of D → (3, 1)

Length of segment = $\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

AB = $\sqrt{(3-1)^2+(5-3)^2}$

= $\sqrt{4+4}$

= $2\sqrt{2}$

≈ 2.8 units

BC = $\sqrt{(5-3)^2+(3-5)^2}$

= $\sqrt{4+4}$

= $2\sqrt{2}$

= 2.8 units

Therefore, dimensions of the tabletop is 2.8 cm × 2.8 cm.

divide 24 fish into five groups. What is the remainder of this division? Hint: Group the fish into sets of 5, and count how many

vlada-n [284]

Answer:

4.4

Step-by-step explanation:

The answer is 4.4 because if you know that 5*4 equal 20 so 4 can go each of the 5 groups so 24-20 leaves you with 4 so your answer is 4 remainder 4
