Help please, i give brainlist

the surface is around 65

Answer:

It is 2.

Step-by-step explanation:

The equation becomes -2y=-4x=5

But you divide by -2 to get y solo. So -4/-2=2.

Answer:

slope = 2

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 )

Given

4x - 2y = 5 ( subtract 4x from both sides )

- 2y = - 4x + 5 ( divide all terms by - 2 )

y = 2x + [tex]\frac{5}{2}[/tex] ← in slope- intercept form

with slope m = 2

Answer:

volume of rectangular prism =l×w×h

volume of rectangular prism =4cm×2cm×7cm

volume of rectangular prism =56cm³

Answer:

The volume of the rectangular prism is [tex]56cm^3[/tex]

Step-by-step explanation:

To find the volume of a rectangular prism, you need to multiply the length, width, and height of the rectangular prism altogether. In this case, the length is 4cm, the width is 2cm, and the height is 7cm. So the volume of the rectangular prism would be [tex]7*2*4[/tex] = [tex]7 * 8[/tex] = [tex]56cm^3[/tex].

Answer:

1.) 2.5cm

2.) 1 3/4

3.) 1.6

4.) 4/5

5.) 18.84

Step-by-step explanation:

So the radius is half of the diameter, so the first one would be:

5 ÷ 2 = 2.5

We do the same thing for the next one:

3 1/2 ÷ 2 = 1 3/4

Now we have to go backwards because we have the radius and we're trying to find the diameter:

0.8 x 2 = 1.6

And the next one:

3/5 x 2 = 4/5

Now to find the circumference, we multiply the diameter by pi (3.14)

6 x 3.14 = 18.84

let me know if any of these are wrong

hope this helps:)

Answer: Annalise says that Philip will earn $320 more at First Bank than at GrandBank.

Step-by-step explanation:

Formula for Simple interest = Principal × Rate × Time

At GrandBank, the simple Interest will be:

= $2000 × 6% × 8

= $2000 × 0.06 × 8

= $960

At First Bank, the Simple interest will be:

= $2000 × 8% × 8

= $2000 × 0.08 × 8

= $1280

Based on the above, Philip will earn ($1280 - $960) = $320 more at First Bank.

Answer:

The volume of the cylinder is 367.6 M^3

Step-by-step explanation:

Mathematically, we have the volume of a cylinder calculated as follows;

V = pi * r^2 * h

r is the base radius given as 3 m

h is the height given as 13 m

So, we have the volume as;

V = 22/7 * 3^2 * 13 = 367.6 M^3

Answer:

367.6 m³

Step-by-step explanation:

h=13       r=3                              identify variables

V= πr² h                                  use volume of a cylinder formula

V=π(3)²(13)                            substitute variables into formula

V= 367.56634047                   multiply

V=367.6 m³                            round to the nearest tenths place

Answer:

75 %

Step-by-step explanation:

To solve for the above question,

The percentage of pupils that submitted their project on time

= Number of pupils that submitted their project on time/Number of pupils × 100

Number of pupils that submitted their project on time = 30 pupils

Number of pupils = 40 pupils

= 30/40 × 100

= 75 %

The percent of the pupils that submitted their project on time is 75%

Answer:

x = 16

Step-by-step explanation:

In a parallelogram , consecutive angles sum to 180° , then

3x + 5 + 9x - 17 = 180

12x - 12 = 180 ( add 12 to both sides )

12x = 192 ( divide both sides by 12 )

x = 16

take off the parentheses and then take off the number and the degrees symbol with the plus sign

take off the parentheses from the 9,-,17, and the degrees symbol

now your left with 2 x'

Answer:

1. 3.48 i think but 2. is 115

Step-by-step explanation:

For h(x), to find out the maximum, you would need to use this formula: [tex]c-(\frac{b^{2} }{4a} )[/tex]

We are given the equation: [tex]h(x)=-x^{2}+4x-2[/tex].

So, a = -1, b = 4, and c = -2. Then, substitute the numbers into the formula:

h(x)'s maximum = [tex]c-(\frac{b^{2} }{4a} )[/tex]

                          = [tex](-2)-(\frac{(4)^{2} }{4(-1)} )[/tex]

                          = [tex](-2)-(\frac{16 }{-4} )[/tex]

                          = [tex](-2)-(-4)[/tex]

                          = [tex]2[/tex]

For g(x), to find out the maximum, just look at the highest point of y on the graph of the function, which is 2.

Thus, the answer you have chosen is the correct answer, which is choice 3: functions g and h have the same maximum of 2. Hope this helps :)

Step-by-step explanation:

Parallel lines are lines of equal distance apart (equidistant), that are on the same plane but they never meet

Perpendicular lines meet thus they are not parallel lines

Also, lines that intersect , meet, thus they are not parallel lines

Answer:

scale 1 was 15% off and SCALE 2 was 6% off

Step-by-step explanation:

Scale __ Measured Weight ____Actual Weight

1_________85 oz _______________100 oz

2 ________ 47 oz _______________ 50 oz

Percentage error :

[(|measured - actual |) ÷ actual] * 100%

Scale 1 :

|85 - 100| = 15 oz

15 / 100 * 100% = 15%

Scale 2 :

|47 - 50| = 3 oz

3 / 50 * 100% = 0.06 * 100% = 6%

Hence, scale 1 was 15% off while SCALE 2 was 6%

Answer:

8.009 , 8.09 , 8.7 , 8.7082

Step-by-step explanation:

Convert all numbers to decimals.

8.009 = 8.009

8.7 = 8.7

8.09 = 8.09

8.7082 = 8.7082

Arrange the numbers in ascending order.

8.009 , 8.09 , 8.7 , 8.7082

Answer:

The answer is "between 0.10 and 0.05".

Step-by-step explanation:

For sample 1:

[tex]n_1 = 25\\\\\bar{x_1} = 90.00\\\\ s_1 = 9\\\\[/tex]

For sample 2:

[tex]n_2 = 25\\\\ \bar{x_2} = 95.08\\\\ S_2 = 12\\\\[/tex]

Calculating the null and alternative hypotheses:

[tex]H_O : \mu_1 = \mu_2 \\\\ H_Q : \mu_1 <\mu_2[/tex]  

Calculating the test statistic:

[tex]Z= \frac{90-95.08}{ \sqrt{\frac{9^2}{25}+\frac{12^2}{25}}} \\\\ =\frac{-5.08}{ \sqrt{\frac{81}{25}+\frac{144}{25}}}\\\\=\frac{-5.08}{ \sqrt{\frac{81+144}{25}}}\\\\=\frac{-5.08}{ \sqrt{\frac{225}{25}}}\\\\=\frac{-5.08}{ \frac{15}{5}}\\\\=\frac{-5.08}{3}\\\\= -1.693[/tex]

Calculating the conservative degrees of freedom:

[tex]DF = min (n_1 -1, n_2 - 1) = min(25-1, 25-1) = 24[/tex]

by using Excel the p-value for left tailed test and for test statistic will be [tex]-1.693[/tex] with [tex]DF = 24[/tex].

[tex]\to p-value = TDIST(1.693, 24, 1) = 0.0517\ \ \ \ i.e, \bold{0.05 < p-value < 0.10}[/tex]

Answer:

3/4

Step-by-step explanation:

Tangent is opposite/adjacent side. To get the adjacent side, use the Pythagorean Theorem:

a² + b² = c²

3² + b² = 5²

9 + b² = 25

b² = 16

√b² = √16

b = 4

tan(O) = opposite/adjacent side

tan(O) = 3/4
