How can we write 0.7 in words?​

Answer:

A is the answer.

Step-by-step explanation:

In option A, there are 9 red boxes and 3 blue boxes

If we simlify,

9 : 3 = 3 : 1 = 1 : 1/3

Hope you understand

Answer: Grid A

Step-by-step explanation:

The ratio red:blue is simplified to 1:1/3.

To make things easier, we can expand it so that both sides add up to 12(total number of squares in a grid).

We can multiply both sides by 9.

1 x 9= 9

1/3 x 9= 3

Now the ratio red:blue is 9:3, which adds up to 12.

Grid A is the only grid where there are 9 red squares and 3 blue squares.

Answer:

Step 3

Step-by-step explanation:

The solution is given in the image attached. The steps are:

Step 1:

[tex]2x-\frac{1}{4} -\frac{3}{5}x=\frac{55}{4}[/tex]

Step 2: simplifying the coefficients of x:

[tex]2x -\frac{3}{5}x-\frac{1}{4}=\frac{55}{4}\\\frac{10x-3}{5} -\frac{1}{4}=\frac{55}{4}\\\frac{7x}{5} -\frac{1}{4}=\frac{55}{4}[/tex]

Step 3: Adding 1/4 to both sides

[tex]\frac{7x}{5} -\frac{1}{4}+\frac{1}{4} =\frac{55}{4}+\frac{1}{4}\\ \frac{7x}{5}=\frac{55+1}{4}\\ \frac{7x}{5}=\frac{56}{4}\\[/tex]

Step 4: Multiplying both sides by 5/7

[tex]\frac{7x}{5}*\frac{5}{7} =\frac{56}{4}*\frac{5}{7} \\x=10[/tex]

The addition property of equality states that if a number is added to both sides of an equation, the equation is still valid (i.e the equation is still the same). From the steps above, The addition property of equality was applied in step 3

Answer:

The 2 pink ones

explanation: I got this right

The two pink diagrams in the given figure are parallelograms.

A unique kind of parallelogram created with parallel lines is called a parallelogram.

A parallelogram can have whatever angle between its neighboring sides, but for it to be a parallelogram, it's opposite sides must be parallel. If a quadrilateral's opposite sides are parallel and congruent, it will be a parallelogram.

So a rectangle both with pairs of separate sides being parallel and equal is known as a parallelogram.

The word "parallelogram" is a translation of the Greek term "parallelogrammon," which means "confined by line segments." As a result, a quadrilateral that is surrounded by parallel lines is called a parallelogram.

Answer:

m<GEC = 17.9 deg

Step-by-step explanation:

First, use the Pythagorean theorem to find the length of GE.

(GE)^2 = (E?)^2 + (?G)^2

I am using ? in place of the front right corner point name that is not visible.

(GE)^2 = 12^2 + 3^2

GE = 12.3693

In triangle EGC, for angle GEC, GE is the adjacent leg, and GC is the opposite leg. We use the tangent.

tan GEC = opp/adj

tan GEC = GC/GE

tan GEC = 4/12.3693

tan GEC = 0.32338

Use inverse tangent to find the angle.

m<GEC = 17.9 deg

The angle ∠GEC of a cuboid will be:

"17.9°"

According to the question,

Three dimensions,

AC = 4 cm

EH = 12 cm

GH = 3 cm

By using Pythagoras theorem,

→ (GE)² = (EH)² + (GH)²

By substituting the values,

           = (12)² + (3)²

           = 144 + 9

           = 153

     GE = √153

           = 12.3693

Now, In ΔEGC

here, Adjacent leg = GE

        Opposite leg = GC

→ tan GEC = [tex]\frac{Opposite}{Adjacent}[/tex]

                 = [tex]\frac{GC}{GE}[/tex]

                 = [tex]\frac{4}{12.3693}[/tex]

                 = 0.32338  

Hence, by using inversing tangent

m∠GEC = 17.9°

Thus the above answer is correct.

Answer: A: 3/2

Step-by-step explanation:

When we have a line that passes through the points (x1, y1) and (x2, y2), the slope of this line is:

s = (y2 - y1)/(x2 - x1)

In this graph we can see that the line passes through the points:

(0, - 3) and (2, 0)

Then the slope is:

s = (0 - (-3))/(2 -0) = 3/2

Then the correct option is A.

The gradient of the line shown above is  A:  [tex]\frac{3}{2}[/tex]

Slope of the line that passes through two points [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] is :

slope  [tex]=\frac{(y_2 - y_1)}{(x_2 - x_1)}[/tex]

Step-by-step explanation:

Since we have given that

Quantity of orange juice = 30 ml

Quantity of apple juice = 20 ml

Quantity of coconut juice = 50 ml

Total quantity of cocktail = 100 ml

So, the ratio of orange juice to apple juice to coconut juice is given by

=30:20:50

= 3:2:5

Total ratio=3+2+5

=10

So, proportion of the cocktail of apple juice is given by

2/10×100

=1/5×100

=20%

Hence, the proportion of the cocktail is 1/5 apple juice

Answer:

slope = -2

y-intercept = 2

equation: y = -2x + 2

Step-by-step explanation:

The equation of a line is

y = mx + b

We need to find the slope, m, and the y-intercept, b.

The graph crosses the y-axis at y = 2, so the y-intercept, b, equals 2.

Now we have

y = mx + 2

slope = m = rise/run

We see points (1, 0) and (0, 2) on the graph. Starting at (1, 0), we go up 2 units. That is a rise of 2. Then we go 1 unit left. That is a run of -1.

slope = m = rise/run = 2/(-1) = -2

The slope is -2.

The equation is

y = -2x + 2

Answer:

y=-2x+2

Step-by-step explanation:

Using rise over run the line travels down 2 and right one from one point to another giving u -2/1 or -2 as the slope and it passes through the y-axis at 2 giving you a y-intercept of 2 and the equation y=-2x+2.

Answer:

Step-by-step explanation:

This is a binomial probability distribution because there re only 2 possible outcomes. It is either a surveyed company outsourced some part of their manufacturing process in the past two to three years. The probability of success, p would be that a randomly selected company x, outsourced some part of their manufacturing process in the past two to three years. From the information given, p = 54/100 = 0.54

Number of success, x = 338

Number of samples, n = 555

We want to determine the probability that 338 or more companies outsourced some part of their manufacturing process in the past two or three years which is expressed as

P(x ≥ 338)

From the binomial probability calculator,

P(x ≥ 338) = 0.0006

The percentage is 0.0006 × 100 = 0.06%

Answer: 96

Step-by-step explanation:

A palindrome is a number that is the same when reading in both ways (right to left, and left to right), for example, 121

Then, we have 9 digits, and all the digits need to be even.

the options are: 0, 2, 4, 6, 8.

Now, we can tink a 9 digit number as 9 empty slots, and in each slot, we can put a number.

But because this is a palindrome, the first digit must be equal to the ninth, and the second digit must be equal to the eight, and so on.

So we can tink it as actually only 5 slots, where in each slot, we can put an even number, now let's count the options that we have in each selection.

For the first digit we have 4 options: 2, 4, 6 and 8 (0 is not counted here because if the first digit was a 0, then this would not be a 9 digit number).

for the second digit, we have also 4 options (because we already toked one, but now the 0 can be chosen)

for the third digit, we have 3 options

for the fourth digit, we have 2 options

for the fifth digit, we have only one option.

The total number of combinations is equal to the product of the number of options for each selection:

C = 4*4*3*2*1 = 96

Step-by-step explanation:

To multiply rational expressions, simply multiply the numerators together (the tops) and the denominators together (the bottoms).

For example:

[tex]\frac{x+a}{y+b}\times\frac{x+c}{y+d}[/tex]

[tex]= \frac{(x+a)(x+c)}{(y+b)(y+d)}[/tex]

[tex]=\frac{x^{2}+ax+cx+ac}{y^{2}+by+dy+bd}[/tex]

To divide by a rational expression, multiply by its reciprocal.  In other words, flip the fraction, then multiply.

For example:

[tex]\frac{x+a}{y+b}\div\frac{x+c}{y+d}[/tex]

[tex]=\frac{x+a}{y+b}\times\frac{y+d}{x+c}[/tex]

[tex]=\frac{(x+a)(y+d)}{(x+c)(y+b)}[/tex]

[tex]=\frac{xy+dx+ay+ad}{xy+bx+cy+bc}[/tex]

Answer:

Justine needs to score a 100 to have an average of 93%.

Step-by-step explanation:

Given:

Justin scores 85, 92 and 95 on his science tests.

To find:

The score that he needs to earn to have an average of 93%?

Solution:

Let the score in next science test = [tex]x[/tex]

Formula for Average/Arithmetic Mean is given as:

[tex]Average = \dfrac{\text{Sum of all observations}}{\text{Total number of observations}}[/tex]

Here we have 4 number of total observations and average is 93%.

Now, put all the values here:

[tex]93 = \dfrac{85 +92+ 95+x}{4}\\\Rightarrow 93\times 4=85 +92+ 95+x\\\Rightarrow 372=272+x\\\Rightarrow x = 372-272\\\Rightarrow x = 100[/tex]

So, Justin needs to score 100 to have an average of 93%.

Answer:

3x - 21 = 3(x + 7).

Step-by-step explanation:

3x - 21 = 3(x + 7)

3x - 21 = 3x + 21

3x - 3x = 21 + 21

0 = 42

Since the two are not equal, this equation has no solution.

3x - 21 = 3(x - 7)

3x - 21 = 3x - 21

3x - 3x = -21 + 21

0 = 0

Since the two are equal, this equation has infinitely many solutions.

3x - 21 = x - 7

2x = 14

x = 7

This equation has one solution.

Since there is only one choice that makes sense, the answer won't be all of the choices.

The answer is A. 3x - 21 = 3(x + 7).
