B. 2.3
C. 25.6
D. 15.6

Answer:

49

Step-by-step explanation:

Answer:

for the first on its a=24 and for the second its a= 48

Step-by-step explanation:

for the first one you have to find the length which is 8 and then you find the width which is 3 then you multiply that to get 24

for the second one you find the base which is the strait line which is 8 then you find the height which is 6 then you multiply it to get 48 i hopes this helped!

Answer:

1 : 5

Step-by-step explanation:

Given the ratio

19 : 95 ( divide both parts by 19 )

= 1 : 5 ← in simplest form

Answer:

2, 3, 4, 5, 6

Step-by-step explanation:

Let's break this inequality into two parts:

Solve Inequality I.

Add 1 to both sides.

Divide both sides by 3.

Solve Inequality II.

Subtract 2x from both sides.

Add 1 to both sides.

Combine these two inequality solutions.

Integer solutions to this inequality would be any integer between 1 (4/3 = 1.3...) and 7, exclusive.

These five numbers are 2, 3, 4, 5, 6.

Step-by-step explanation:

Answer: Let's simplify step-by-step.

3x−2

There are no like terms.

So it going to be the same, =3x-2

Answer:

2x + 2 + x

Step-by-step explanation:

Answer:

y=4/3x+2

Step-by-step explanation:

The equation is in standard form right now, which is ax+by=c

your question is asking for slope intercept form, which is y=mx+b

so we need to isolate y onto 1 side

-4x+3y=6

add 4x to both sides

3y=4x+6

divide by 3 on both sides

y=4/3x+2

Answer:

the difference in these two temperatures is 146.3°C

Step-by-step explanation:

The computation of the difference in these two temperatures is as follows:

= Highest temperature - lowest temperature

= 58.0°C - (-88.3°C)

= 58.0°C + 88.3°C

= 146.3°C

Hence, the difference in these two temperatures is 146.3°C

It is determined by the applying the above formula and the same is relevant

Reflection over x-axis results in:

Therefore the new function is:

Answer:

b = 5.2

c = 3.5

Step-by-step explanation:

By 45°- 45° - 90° triangle theorem:

[tex]c = \frac{1}{ \sqrt{2} } \times 5 \\ \\ c = \frac{1}{ 2} \times 5 \sqrt{2} \\ \\ c = 2.5 \times 1.414\\ \\ c = 3.535 \\ \\ c \approx \: 3.5[/tex]

By 30°- 60° - 90° triangle theorem:

[tex] b = \frac{ \sqrt{3} }{2} \times (2 \times 3) \\ \\ b = 3 \sqrt{3} \\ \\ b = 3 \times 1.732 \\ \\ b = 5.196 \\ \\ b \approx 5.2[/tex]

Answer:

perimeter = 14

area = 6

Step-by-step explanation:

p = 4 + 3 + 7

a = L × w

2

Perimeter: 14m²n²cm

Area: 28m²n²

height: 4m²

length: 7mn²

base: 3mn²

Perimeter =?

Area=?

Perimeter: a + b + c

Area: length × height

Perimeter: a+b+c

= 4m²+7mn²+3mn²

= 14m²n² cm

Area: l×h

= 4m²×7mn²

= 28m²n²

Answer:

hmm. I would say right.

Step-by-step explanation:

The angle when you flip your triangle is 90 degrees.

Answer:

maybe 23

Step-by-step explanation:

Answer:

a^-b= 1/a^b

a^b/a^c= a^b-c

a^c/b^c= (a/b)^c

Step-by-step explanation:

Those are the right answers.

Answer:

73

Step-by-step explanation:

17+90+C=180 since it is a straight angle and yeah.

17+90=107+c=180

180-107=73

Answer:

62.5%

Step-by-step explanation:

There are a total of 8 options.

We are trying to get 5 of the 8.

5/8 = 0.625 = 62.5%

Answer:

(0.5, 1.3)(0.5, 1.3)

Step-by-step explanation:

Given equations are:

As we can see that the given equations are linear equations which are graphed as straight lines on graph. The solution of two equations is the point of their intersection on the graph.

We can plot the graph of both equations using any online or desktop graphing tool.

We have used "Desmos" online graphing calculator to plot the graph of two lines (Picture Attached)

We can see from the graph that the lines intersect at: (0.517, 1.267)

Rounding off both coordinates of point of intersection to nearest tenth we get

(0.5, 1.3)

Hence,

(0.5, 1.3) is the correct answer

Keywords: Linear equations, variables

Answer:

yes more points

I Had The Same Question And Got This Correct.

Answer:

-3,2

-4i

ON E2020

Have a Great Day :)

Point x is -3 + 2i , point w is 4 + 0i and point z will be 0 + -4i.

Complex numbers are helpful in finding the square root of negative numbers.

A complex number is the sum of a real number and an imaginary number.

The idea of a complex number has come by solving a quadratic equation that has root as negative under root.

If we solve x² + 1 = 0 ⇒ x = √(-1) which is called as iota(i).

Given points, x,y, and z in a complex plan where an x-axis is a real number and the y-axis is an imaginary (i.e. i ) number.

So,

Point x is 3 units to the negative side and 2 units up so its coordinate will be (-3, 2i) so -3 + 2i.

Point w is 4 units to the positive side and 0 units up so its coordinate will be (4,0i) so 4 + 0i.

Point z is 4 units downside so its coordinate will be (0,-4i) so  0 + -4i.
