Hmm, thats wrong actually, I believe its C?

DE is 30, so AD is also 30

A full circle is 360

ACE = 360- Ad-de

Ace = 360-30-30 = 300

Ac is half of ace

Ac = 300/2 = 150

The answer is b 150

Answer:

Option A

Step-by-step explanation:

In order to find the answer to this question you must change the mixed numbers into improper fractions and then solve.

[tex]1\frac{3}{4} \times\frac{2}{4}[/tex]

Convert into improper fraction:

[tex]4\times1=4+3=7[/tex]

(Remember to keep the denominator the same)

[tex]\frac{7}{4} \times\frac{2}{4}[/tex]

Now multiply:

[tex]7\times2=14[/tex]

[tex]4\times4=16[/tex]

[tex]=\frac{14}{16}[/tex]

Hope this helps.

Convenience sampling

Step-by-step explanation:

When a researcher gives more credence to ease when performing its sampling procedure, such sampling process may be referred to as convenience sampling. As described in the scenario above, rather than having to take a Systematic approach at examining the population so as to decide on the best sampling strategy to employ, the reporter of the student newspaper decides to take the easy path towards gathering the opinion of students by interviewing the first 12 students who are willing to give their opinion without any further consideration. Here, the reporter failed to eliminate any sort of possible bias which may be present, as all was sacrificed for the sake of convenience or ease.

Answer:

one side of the equation is a quadratic equation, and the other side of the equation is a quadratic expression

Answer:

the 2nd one

Step-by-step explanation:

Step-by-step explanation:

first step is to find the gradient of the line which "m" on the equation

gradient formula is y2 - y1 ÷ x2 - x1 = -½ as shown on the picture we substituted those points given

2nd step is to substitute on the equation y=mx+c

m= -½

y= 3 (you can choose any from those given points but in my case I chose point A)

x= -2

c= ? only unknown variable so we can can calculate it

substitute as shown on the picture to get c= 2

therefore our equation of the line will be y= -½x+2

Answer:

2( w + 3 )

Step-by-step explanation:

Well first off, since theres no common term to factor out, I had to split 6 in half

so 2 w + 6 becomes 2w + 2 x 3.

I then factored out 2 because it's a common term,

which then leaves: 2( w + 3 )

basically, you have to find a common term to factor out, if you don't see one, you have to do something to a number so there's common terms.

Answer:

-26

Step-by-step explanation:

-62 - 4x = 42

-4x=42+62

-4x=104

X=-104/4

X=-26

So the value of the X is -26

Answer:

x = 2 or x = -3

Step-by-step explanation:

Given that ∆ABC ≅ ∆SRT, it follows that their corresponding side lengths are congruent to each other.

Thus:

[tex] RT = BC [/tex]

[tex] (x^2 + x) = 6 [/tex]

Solve for x

[tex] x^2 + x = 6 [/tex]

Subtract 6 from each side

[tex] x^2 + x - 6 = 6 - 6 [/tex]

[tex] x^2 + x - 6 = 0 [/tex]

Factorise

[tex] x^2 + 3x - 2x - 6 = 0 [/tex]

[tex] x(x + 3) -2(x + 3) [/tex]

[tex] (x - 2)(x + 3) [/tex]

x = 2 or x = -3

Responder:

60 triángulos

Explicación paso a paso:

La pregunta está incompleta. No se dio el área del cartón. Digamos que la dimensión del cartón es de 2 m por 0,9 m.

Área del cartón = Largo * Ancho

Dado;

Longitud = 2 m

Ancho = 0,9 m

Área del cartón = 2 * 0.9

Área del cartón = 1.8m²

Si María decide recortar rectángulos con un área igual a 0.03 m², la cantidad de rectángulos que puede obtener del tablero se expresa como;

Número de rectángulos = área del cartón / área de cada parte recortada

Número de rectángulos = 1.8 / 0.03

Número de rectángulos = 60 rectángulos.

Por tanto, el número de rectángulos que puede recortar es de 60 rectángulos.

Tenga en cuenta que se asumió el área del rectángulo y que se puede emplear el mismo cálculo para cualquier otra dimensión dada.

Answer:

4 cans

Step-by-step explanation:

this can be 4 cans because if 6 cans equal 40% it's opposite so 4 cans equal 60% so full is 100% so 60%+40%=100%

Step-by-step explanation:

Step one:

given data

we are told that 10 ounces cost $8.11

and also 16 ounces cost $12

Required

The unit cost per ounce

for the 10 ounce package

the unit cost = 8.11/10=$0.81 per ounce

for the 12 ounce package

the unit cost = 12/16=$0.75 per ounce

the better buy is  12-ounce package because the unit cost is cheaper than that of  the 10-ounce package by $0.06

Answer:

5.5 pages/hour

Step-by-step explanation:

We need to find the unit rate if you write 11 pages in 2 hours. It can be calculated by dividing no of pages to no of hours as follows :

[tex]R=\dfrac{11}{2}\ \text{pages/hour}\\\\=5.5\ \text{pages/hour}[/tex]

So, there are 5.5 pages per hour.

Answer:

  see attached

Step-by-step explanation:

If you plot the points on the graph, you notice that the run (change in x) is 3 for each "rise" (change in y) of -1, so the slope is ...

  m = rise/run = -1/3

The middle point is on the y-axis, so is the y-intercept.

In slope-intercept form, the equation is ...

  y = mx + b . . . . . . where m is the slope (-1/3) and b is the y-intercept (4)

The following diagram(attached) shows how all the Grade Seven students of

Koronadal National Comprehensive High School go to school.

How many grade seven students of koronadal national comprehensive high school are there in all

Answer:

269 students

Step-by-step explanation:

From the venn diagram attached, we can see various given numbers of the students of the different modes of transport to school.

To get how many grade 7 students there are in total, we will add all the students inside the venn diagram simply because the set of grade 7 students are represented by those inside the venn the venn diagram while the number 100 outside the venn diagram is not a member of the set of grade 7 students which we are dealing with.

Thus,

Total number of grade 7 students = 76 + 19 + 15 + 17 + 55 + 20 + 67 = 269
