Answer:

[tex]42 \times 48[/tex]

Step-by-step explanation:

[tex]25 \times 36=900\\52 \times 63=3276[/tex]

[tex]34 \times 42 = 1428\\ 43 \times 24=1032[/tex]

[tex]54 \times 56 = 3024\\45 \times 65= 2925[/tex]

[tex]42 \times 48 = 2016\\ 24 \times 84= 2016[/tex]

[tex]32 \times 43 = 1376\\ 23 \times 34=782[/tex]

The calculation for [tex]42 \times 48[/tex] has the same results from switching the digits.

Answer:

25 × 36 = 900

52 × 63 = 3 276

34 × 42 = 1 428

43 × 24 = 1 032

54 × 56 = 3 024

45 × 65 =  2 925

42 × 48 = 2 016

24 × 84 = 2 016

32 × 43 = 1 376

23 × 34 = 782

Answer:

x = 22°

Step-by-step explanation:

Given corner URV = x and because of symmetry of Z-corners, that corner by definition is the same as corner DVR.

So corner SVR = V = x

R = 44°

S = 5x + 4°

V = x

In any triangle the three corners add up to 180°

Combine all this info and you get:

44 + 5x + 4 + x = 180

Solve for x (means write as x =...)

5x + x = 180 - 4 - 44

6x = 132

x = 132/6

x = 22°

Answer:

With points A, B and C a right triangle is formed.

Given that BC ⊥ CA, then m∠C = 90°.

The addition of the angles of a triangle is equal to 180°, therefore:

m∠A + m∠B + m∠C = 180°

Substituting with m∠C = 90°:

m∠A + m∠B + 90° = 180°

m∠A + m∠B = 180° - 90°

m∠A + m∠B = 90°

Answer:

B

Step-by-step explanation:

Answer:

Number of sides = 18

Step-by-step explanation:

Using the formula given below for this

=> [tex](n-2)*180 = measure of interior angles[/tex]

=> (n-2)*180 = 2880

Dividing both sides by 180

=> n-2 = 16

Now, Adding 2 to both sides, we get

=> n = 18

Step-by-step explanation:

a) To create an equation

X+X =7

so what's X over here is

7² = x²

X=3.5

b) Real numbers are mixture of irrational and rational numbers so √5 and √6 are irrational where as 5 and 6 are not but they two are equal to each other.

Explaining the equation:

√5 +√6 = √11

5 +6 = 11

√11 =11

√= 11 ÷ 11

√= 1

So if root is 1 then -1 is -√

this is the answer propably

Answer:

The answer is B

Step-by-step explanation:

When you reflect it over the x-axis you have to change the coordinates of each number.

Answer:

B. (1, -1), (1, -4), (3, -1)

Step-by-step explanation:

If a triangle is reflected across the x-axis, it's y coordinate values will become negative or positive if it's already negative. It uses the rule (x, -y)

(1, 1) → (1, -1)

(1, 4) → (1, -4)

(3, 1) → (3, -1)

Only B. (1, -1), (1, -4), (3, -1) is correct.

Answer:

i believe it is c

Step-by-step explanation:

Answer:

A

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 )

y = [tex]\frac{1}{5}[/tex] x - 5 ← is in slope- intercept form

with slope m = [tex]\frac{1}{5}[/tex]

Parallel lines have equal slopes, thus parallel line has slope of [tex]\frac{1}{5}[/tex]

The line crosses the y- axis at (0, 6) ⇒ c = 6

y = [tex]\frac{1}{5}[/tex] x + 6 ← equation of parallel line → A

the equation of the line that passes through the point (0,6) and is parallel to the line with the equation y = 1/5X - 5 is y = 1/5x +6.

A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are included. Sometimes, the aforementioned is referred to as a "linear equation of two variables," with y and x serving as the variables.

Given A line passes through the point (0,6) and is parallel to the line with the equation y = 1/5X - 5

Since the two lines are parallel to each other

thus, their slope would be equal

Slope intercept form of the Second line:

y = 1/5x + c

Given that line passes through (0, 6)

From above equation

6 = 1/5* 0 +c

Hence, c = 6

therefore, the equation of the line y = 1/5x +6.

The expression that returns the probability that a data value in a normal distribution is between a z- score of -0.18 and a z-score of 1.99 is (d) normalcdf(-0.18, 1.99)

To calculate the probability between two z-scores is to calculate the area between the z-scores.

This is done using the following syntax:

normalcdf(lower bound, upper bound)

From the question, the lower and the upper z-scores are -0.18 and 1.99

So, the formula would be normalcdf(-0.18, 1.99)

1st Choice

Step-by-step explanation:

The fastest way to do this is by thinking of translations. If you are trying to move it left or right, it will be inside the cube root. If you want to move it vertically, it will be outside the root. In the graph, the child function is moving from the parent function to the right. This means we can eliminate choices C and D. We are left with A and B. A is the right choice because you take the negative of the direction you want to move in. Thus, you have your answer.

Answer: 31.42 seconds

Step-by-step explanation:

Given that:

Time taken (T) for a pendulum to complete a full swing or cycle is represented by the equation:

T = 2 π √(L/32)

T = time taken to complete a full swing in Seconds

L = Length of the pendulum measured in feet

If length (L) of the pendulum = 8 feet

Time taken (T) =?

Inputting our values :

T = 2 π √(8/32)

T = 2 π √(1/4)

T = 2 π 0.5

T = 10 π

T = 10 × 3.142 = 31.42seconds

Answer:

arc AB = 70°

Step-by-step explanation:

The measure of arc AB in the circle is 60°

An arc is any smooth curve joining two points in the circle.

Given is circle, we need to find the measure of the arc AB,

In triangle, ΔBGD,

∠BGD = 180°-50° [linear pair]

∠BGD = 130°

Therefore,

∠GDB = 180°-(∠BGD+∠B)

∠GDB = 180°-(20°+130°)

∠GDB = 30°

Now,

arc AB = 2 ∠GDB

arc AB = 2(30°)

arc AB = 60°

Hence, the measure of arc AB in the circle is 60°
