Answer:

c, d.

Step-by-step explanation:

c; A vertical stretch by 4 will put the coefficient (in this case 4) in front of your original equation.

d; the negative in front of the whole equation (-4x) will flip the graph across the x-axis.

Answer:

I think it's -15 I'm not 100% sure

Answer: ~14°, ~62°

Step-by-step explanation:

See image. You should be able to easily calculate the last two angles.

Answer:

[tex]\boxed {\boxed {\sf A. \ 18}}[/tex]

Step-by-step explanation:

The two angles are inside a right angle. The small box signifies a right angle/ 90° angle.

Therefore, the sum of the angle measures must equal 90. We can set up an equation.

[tex]56+(x+16)=90[/tex]

Combine the like terms on the right side. The 2 constants: 56 and 16 can be added.

[tex](56+16)+x=90\\[/tex]

[tex]72+x=90[/tex]

Since we are solving for x, we must isolate the variable. 72 and x are being added. The inverse of addition is subtraction, so subtract 72 from both sides.

[tex]72-72+x=90-72[/tex]

[tex]x=18[/tex]

x is equal to 18 and choice A is correct.

Answer:

4x+2(x-6)=12

[tex]4x {}^{2} - 24 + 2x - 12 = 12 \\ 4x {}^{2} - 36 + 2x = 12 \\ 4x {}^{2} + 2x = 12 + 36 \\ 4x {}^{2} + 2x = 48 \\ 4x { }^{2} + 2x - 48 = 0[/tex]

The numbers as a single digit times a power of ten are ; 1. 4x10^-9, 2. 4x10^10, 3. 5x10^7, 4. 2x10^-5

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division. The Numbers constants, variables, operations, brackets can all be represented by mathematical symbol; which can also be used to indicate the logical syntax's order of operations and other features.

Therefore, each number as a single digit times a power of ten.

1. 0.000000043 is [tex]4 \times 10^{-9}[/tex]

2. 43560000.000 is[tex]4 \times 10^{10}[/tex]

3. 56.234567  is [tex]5 \times 10^7[/tex]

4. 0.00002346 is [tex]2 \times 10^{-5}[/tex]

Hence, The numbers as a single digit times a power of ten are ; 1. 4x10^-9, 2. 4x10^10, 3. 5x10^7, 4. 2x10^-5

Answer:

your answer will be option B) y=20x+30

Step-by-step explanation:

have a great day

The given area presented on the coordinate plane has dimensions

given by the lengths of the line joining the vertices.

Response:

The given figure can be taken as a composite figure of wo triangles and

a trapezium.

Area of the triangle at the top, A₁ = 0.5 × 4.5 × 1 = 2.25

Area of the trapezoid, A₂ = 0.5 × (6 + 4.5) × 1 = 5.25

Area of the bottom triangle, A₃ = 0.5 × 2 × 6 = 6

Therefore;

Area of the figure, A = A₁ + A₂ + A₃

Which gives;

A = 2.25 + 5.25 + 6 = 13.5

Answer:

6

Step-by-step explanation:

Let x = number of hours.

Let y = cost.

The fixed cost is $11.

The cost per hour is $2.

For x hours, the cost per hour is 2x.

y = 2x + 11

23 = 2x + 11

12 = 2x

x = 6

Answer:

the smaller batch

Step-by-step explanation:

Proportion of coconut in the smaller batch = 2/1 = 2

Proportion of coconut in the bigger batch = 5/3 = 1.67

2 is greater than 1.67. So, the proportion of sugar in the smaller batch is stronger

Step-by-step explanation:

I did this last year:)

Answer:

Step-by-step explanation:

total mass of people = 50× 5 = 250kg

height = 20m

force = mass × g = 250× 10 ( taking g= 10m/s²)

work done = force × distance

= 2500× 20

Given:

Length of a box is 9 inches, width is 2 inches and height is 1.5 inches.

The cost of silver coating is $2.50 per sq. inches.

To find:

The total cost of silver coating for the box.

Solution:

The total surface area of a cuboid is

[tex]A=2(lb+bh+hl)[/tex]

Where, l is length, b is breadth and h is height.

Putting [tex]l=9,b=2,h=1.5[/tex], we get

[tex]A=2(9\times 2+2\times 1.5+1.5\times 9)[/tex]

[tex]A=2(18+3+13.5)[/tex]

[tex]A=2(34.5)[/tex]

[tex]A=69[/tex]

So, the total surface area of the box is 69 square inches.

Cost of silver coating is $2.50 per sq. inches. So, the cost of silver coating for the box is

[tex]Cost=69\times 2.50[/tex]

[tex]Cost=172.50[/tex]

Therefore, the cost of silver coating for the box is $172.50.

Answer:

0.007 kg

Step-by-step explanation:

There are 25 packets

Each packet contains 4 biscuits.

The total number of biscuits = 4 * 25

The total number of biscuits = 100

100 biscuits = 0.7 kg

1 biscuit is 0.7 kg / 100

1 biscuit is 0.007 kg

If you are not sure of this, put it in a calculator.

Just out of curiosity  note that 1 kg = 1000 grams

0.007 kg = 0.007 * 1000 = 7 grams each.

use 0.007 as your answer.
