Find a number if 7/10 of it is 0.8.

Answer:

sorry i cant help

Step-by-step explanation:

Answer:

156.

Step-by-step explanation:

130/5 = 26.

130 + 26 = 156.

The equation of a line in point-slope form is  (y + 8) = 4(x - 2).

We know lines have various types of equations, the general type is

Ax + By + c = 0, and the equation of a line in slope-intercept form is

y = mx + b.

Where slope = m and b = y-intercept.

the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.

Given, A line passes through the point (x₁, y₁) ⇒ (2,-8) and had a slope of 4.

We know the equation of a line in point-slope form is (y - y₁) = m(x - x₁).

∴ The equation of this line is (y + 8) = 4(x - 2).

Answer:

68.8

Step-by-step explanation:

100% = x number

96% = 66

so 100%

= 68.75

to the nearest tenth is 68.8

Answer:

7

Step-by-step explanation:

We can solve this problem by making an equation.

Let x represent the second number

3x + 2 will be the first number because it is 2 more than triple x

This makes our equation:

3x + 2 + x = 30

Combine like terms

4x + 2 = 30

Subtract 2 from both sides

4x = 28

Divide both sides by 4

x = 7

The smaller number aka the second number is 7

Answer: Monitors A and B

Step-by-step explanation:

The similar monitors based on display resolution are those with similar ratios.

Take the ratios to their simplest forms to see which are similar.

Monitor A

= 640 : 480

= 16 : 12

= 4 : 3

Monitor B

= 800 : 600

= 8 : 6

= 4 : 3

Monitor C

= 1,280 : 800

= 32 : 20

= 8 : 5

Monitors A and B are similar as they have the same display ratio.

Answer:

The sale price is $34

Step-by-step explanation:

If we are given the regular price P and the markdown percentage r, we follow these steps:

1) Calculate the markdown or discount amount M.

M = P*r/100

2) Subtract it from the regular price:

S = P - M

S is the sale price.

Example: The regular price is $40 and the markdown percentage is 15%. Thus:

1) M = $40*15/100 = $6

2) S = $40 - $6 = $34

The sale price is $34

Answer: Point A

Step-by-step explanation:

The temperature at midnight is;

= 5 - 15

= -10°C

Looking at the number line, one can surmise that the scale is in multiples of 5. This means that C is 10, B is -5 and A is -10.

With point A being -10°C, it represents the colder midnight temperature.

Answer:

Point A

Step-by-step explanation:

We know that the temperature dropped 15 degrees, and that it was initially of 5°C. So, by midnight, the temperature will be of -10°C (5-15=-10).

We also know that the distance between points is of 5°C. So, the point that we have to mark is point A, which represents -10°C.

Answer:  [tex]-p^2-(q+r)^2[/tex]

Work Shown:

I'm assuming your teacher wants you to factor as much as possible.

[tex]-p^2-q^2-r^2-2qr\\\\-p^2-q^2-2qr-r^2\\\\-p^2-(q^2+2qr+r^2)\\\\-p^2-(q+r)^2\\\\[/tex]

In the last step, I used the rule that [tex](a+b)^2 = a^2+2ab+b^2[/tex]

We cannot factor any further. If the first term was [tex]p^2[/tex] instead of [tex]-p^2[/tex], then we could use the difference of squares factoring rule.

Answer:

Angles measuring 90°, 45°, and 45°: Can make triangle

Angles measuring 27°, 35°, and 108°: Can not make triangle

Angles measuring 82°, 41°, and 57°: Can make triangle

Sides measuring 8 cm, 12 cm, and 5 cm: Can make triangle

Sides measuring 7 in., 4 in., and 13 in: Can not make triangle

Sides measuring 43 cm, 41 cm, and 58 cm: Can make triangle

Step-by-step explanation:

For the angles to form a triangle, there sum must be equal to 180°

Angles measuring 90°, 45°, and 45°

Sum of Angles = 90° + 45° +45° = 180°

Hence, this combination can make triangle.

Angles measuring 27°, 35°, and 108°

Sum of Angles = 27° + 35° + 108° = 170° ≠ 180°

Hence, this combination can not make triangle.

Angles measuring 82°, 41°, and 57°

Sum of Angles = 82° + 41° +57° = 180°

Hence, this combination can make triangle.

For three sides to form a triangle the sum of the two sides must be greater than the length of third side.

Sides measuring 8 cm, 12 cm, and 5 cm

(8 cm + 12 cm) > 5 cm (True)

(8 cm + 5 cm) > 12 cm (True)

(12 cm + 5 cm) > 8 cm (True)

Hence, this combination can make triangle.

Sides measuring 7 in., 4 in., and 13 in

(7 in + 4 in) > 13 in (False)

Hence, this combination can not make triangle.

Sides measuring 43 cm, 41 cm, and 58 cm

(43 cm + 41 cm) > 58 cm (True)

(43 cm + 58 cm) > 41 cm (True)

(41 cm + 58 cm) > 43 cm (True)

Hence, this combination can make triangle.

Answer:

A- Angles measuring 90°, 45°, and 45°.

C- Angles measuring 82°, 41°, and 57°.

D- Sides measuring 8 cm, 12 cm, and 5 cm

F- Sides measuring 43 cm, 41 cm, and 58 cm.

Answer:

$494

Step-by-step explanation:

Given that:

Cost of golf club = $1700

Number of months taken to balance payment after down payment = 6 months

Amount paid per month = $201

The down payment made :

Cost of golf clubs - (monthly payment * number of months)

$1700 - ($201 * 6)

$1700 - $1206

= $494

Hence, the downpayment made = $494

Answer:

Step-by-step explanation:

Equation of line k is   y = (-4/7)x + 1

point (-5,-10); m = -4/7

Line L is perpendicular to k so the perpendicular slope will be 7/4

Equation of line L is  (y - y1) = m(x-x1)

y+10 = (7/4) (x +5)

4y + 40 = 7x + 35

4y = 7x - 5

y = (7/4)x - (5/4)

Answer/Step-by-step explanation:

✔️<1 can be named in two ways using letters, with the middle letter being the letter of the vertex of the angle. Thus is can be named as:

[tex] \angle ADB [/tex] or as [tex] \angle BDA [/tex]

✔️It is unclear to name <1 as <D because <2 can equally be named as <2 since both angles share a common point or vertex D.
