Hello,
Area of the rectangle=
l×w
Apply this formula to this problem:
1/8 yd^2=3/4×w
Divide 3/4 from both side
1/8÷3/4=w
w=4/24 yd.
w=1/6 yd. As a result, the width of this rectangle is 1/6 yard. Hope it help!

Find the value of x.<br><br> pls help! tysm

snow_lady [41]

Answer:

x = 30.

Step-by-step explanation:

The angle next to the 60 degree angle = 180 - 60 = 120 degrees (adjacent angles are supplementary).

Let the angle just above 3x be y. The sum of 3x and y = 120 degrees (as opposite angles of a parallelogram are equal).

We have the following equations.

3x + y = 120............(1)

2x + 90 + y = 180

2x + y = 90.............(2)

Subtracting, (1) - (2):

x = 30.

F(x) = 0.54<br> g(x) = f(x + k)<br> for k=-2

Anton [14]

Answer: The answer is g(x)=f(x+k), therefore it’s k=gx/f.

Step-by-step explanation: You’ll need to isolate the variable by dividing each side by the factors that don't contain the variable.

Riverside Elementary School is holding a school-wide election to choose a school color. Five-eighths of the votes were for blue,

Mnenie [13.5K]

Answer:

Step-by-step explanation:

Let the total number of votes to choose a color = x

Number of votes for blue = $\frac{5}{8}\times x$

Remaining votes = x - $\frac{5}{8}\times x$

= $\frac{8x-5x}{8}\times x$

= $\frac{3}{8}\times x$

Votes for green = $\frac{5}{9}\times (\text{Remaining votes})}$

= $\frac{5}{9}\times \frac{3x}{8}$

= $\frac{5}{24}\times x$

Finally remaining votes = $\frac{3x}{8}-\frac{5x}{24}$

= $\frac{9x-5x}{24}$

= $\frac{4x}{24}$

= $\frac{x}{6}$

Since these votes are for red therefore,

$\frac{x}{6}$ = 48

x = 48×6

= 288

a) Votes for blue are $\frac{5x}{8}$

Therefore, exact number for blue votes = $\frac{5\times 288}{8}$

= 5×36

= 180

b). Votes for green = $\frac{5x}{24}$

= $\frac{5\times 288}{24}$

= 60

c). Since 25 students were absent on that day of the vote, number of students at Riverside Elementary School = 288 + 25

= 313

d). Since seven tenths of the votes for blue were made by the girls.

Therefore, number of girls voted for blue = $\frac{7}{10}\times 180$

= 7×18

= 126

Since total votes made = 288

Therefore, half of the votes made = $\frac{288}{2}$

= 144

Now it's clear that number of votes made by girls is less than half of all the votes.

e). 126 girls voted for blue.

F(x)=6x^2+10x−1 How many distinct real number zeros does f have?

Nonamiya [84]

Answer:

Here, $D>0$ , hence the quadratic equation has two distinct real roots.

Step-by-step explanation:

Given quadratic equation is $6x^{2} +10x-1$ .

Let, the quadratic equation is $ax^{2} +bx+c$ [where, $a,b,c$ are the constants]

The Discriminant $(D)=b^{2}-4ac$

Case $1$ : $b^{2}-4ac>0$ , if the discriminant is greater than $0$ , it means the quadratic equation has two real distinct roots.

Case $2$ : $b^{2}-4ac$ , if the discriminant is less than $0$ , it means the quadratic equation has no real roots.

Case $3$ : $b^{2}-4ac=0$ , if the discriminants is equal to $0$ , it means the quadratic equation has two real identical roots.

Now,

we have $6x^{2} +10x-1$ , where $a=6,b=10,\ and\ c=-1$

∴ $D=b^{2}-4ac$

$=(10)^{2}-(4\times 6\times\ -1)$

$=100+24$

$= 124$

Here, $D>0$ , hence the quadratic equation has two distinct real roots.
