Answer:

9.2 cm and 15% increase

Step-by-step explanation:

1.15*8 = 9.2

percentage increase

new square = 9.2*9.2 =84.64

old area=8*9.2 = 73.6

percentange increase = (84.64-73.6)/73.6 = 15%

Increase the width

As sides of square are equal

Area increases same as length i.e 15%

Slope:-

[tex]\\ \rm\rightarrowtail m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\\ \rm\rightarrowtail m=\dfrac{14-8}{7-10}[/tex]

[tex]\\ \rm\rightarrowtail m=\dfrac{-6}{-3}[/tex]

[tex]\\ \rm\rightarrowtail m=2[/tex]

Answer:

The line passes through the given points are ( 10,8) & (7,14)

here

x₁ = 10

y₁ = 8

x₂ = 7

y₂ = 14

We have been asked to slope of that line which passes through the given points .

Using Formulae

❍[tex] \bf \: m \: = \dfrac{y_{2} - y_{1}}{x_{2} - x_{1}} [/tex]

Put the given value we obtain

[tex] \sf \dashrightarrow \: m \: = \dfrac{14 - 8}{7 - 10} \\ \\ \sf \dashrightarrow \: m \: = \dfrac{6}{ - 3} \\ \\ \sf \dashrightarrow \: m \: = \dfrac{ - 2}{1} \\ \\ \sf \dashrightarrow \: m \: = - 2[/tex]

So, the slope of that line is -2 .

1 5/8

You need to subtract 2/8 from 1 7/8. The numbers are already common denominators, so it's much easier to subtract.

1 7/8-2/8

=1 5/8

Answer:

Product before increasing: 4200

x after increase: 60 * 105% = 63

y after increase: 70 * 110% = 77

Product after increasing: 4851

Percentage increase in the product: 4851 / 4200 * 100 = 115.5%

To make this simpler, we know that [tex]0.15=\frac{15}{100}[/tex], so

   12 times [tex]\frac{15}{100}[/tex] = [tex]12 * \frac{15}{100} =\frac{180}{100} = 1.8[/tex]

The slope is 3/2.

We take any two points, I took (-14,3) and (-12,6) for solving for the formula when finding slope.

The formula is Rise/Run or Change in Y/ Change in X.

y2-y1/x2-x1

6-3/-12-(-14)

= 3/2

Slope is 3/2

Stem and leaf plots are used to visualize data, graphically

The true statement is (b) There are 30 buildings in the county that are taller than 50 feet.

From the stem and leaf plot, we have that the number of leaves is 30

This means that, the total frequency of the dataset is 30

So, the number of buildings taller than 50 feet is 30

Hence, the true statement is (b) There are 30 buildings in the county that are taller than 50 feet.

-18x + 7y = 21 → 7y = 18x + 21 → y = 18/7x + 3

6-3=3

Answer:

2

Step-by-step explanation:

[tex]-18x+7y=21\\\\\implies y=\dfrac{18}{7}x+3[/tex]

when x = 0, y = 3

[tex]y=\dfrac{18}{7}x+6[/tex]

when x = 0, y = 6

Therefore, the scale factor is 2 since the y coordinate has double: 3 x 2 = 6

Answer:

128°

Explanation:

total sum of interior angle in triangle is 180°

Find the missing angle inside the triangle:

180° - 38° - 90°

52°

∵ a straight line always has 180°

Now find for missing exterior angle:

x° + 52° = 180°

x° = 180° - 52°

x° = 128°

Answer:

128 degrees

Step-by-step explanation:

180-52= 128

so your answer is 128 degrees.

Answer:

A = 15 units²

Step-by-step explanation:

The figure has 1 pair of parallel sides and is therefore a trapezium.

The area (A) of a trapezium is calculated as

A = [tex]\frac{1}{2}[/tex] h (b₁ + b₂ )

where h is the perpendicular height between bases and b₁, b₂ are bases

here h = 3, b₁ = 3 , b₂ = 7 , then

A = [tex]\frac{1}{2}[/tex] × 3 × (3 + 7) = 1.5 × 10 = 15 units²

The area of the square is the square of one of its sides. The area of the plate is 15 units².

The area of the square is the square of one of its sides.

[tex]\text{Area of square} = a^2[/tex]

The area of a triangle is half the product of its base and height.

[tex]\rm\text{Area of Triangle} = \dfrac{1}{2} \times Base \times Height[/tex]

The shape of the plate can be divided into two parts a square of side 3 cm and a triangle with of base 4 cm and a height of 3 cm, therefore, the area of the plate is,

[tex]\text{The area of the shape} = \text{Area of the triangle} + \text{Area of the square}[/tex]

                                 [tex]= (\dfrac{1}{2} \times 4 \times 3) + (3 \times 3)\\\\= 6 + 9\\\\=15\rm\ units^2[/tex]

Hence, the area of the plate is 15 units².
