Answer:

104

Step-by-step explanation:

The ratio of boys : girls = 3 : 1 = 3x : x ( x is a multiplier )

There are 52 more boys than girls , so

3x = x + 52 ( subtract x from both sides )

2x = 52 ( divide both sides by 2 )

x = 26, then

3x = 3 × 26 = 78 ← number of boys

Total number = 78 + 26 = 104

Answer:

Start by plotting the y-intercept which is (0, b).

Step-by-step explanation:

Head opposite angles

2x= 3x-42

x= 42°

the angles are 84°

Each of the pairs of opposite angles made by two intersecting lines is called a pair of vertical angles. The value of x is 42 and the measure of the two given angles is 84° each.

Each of the pairs of opposite angles made by two intersecting lines is called a pair of vertical angles.

The two of the given angles are vertically opposite angles, therefore, the measure of the two given angles will be the same.

(2x)° = (3x - 42)°

2x = 3x - 42

Subtract 2x from both sides of the equation and add 42 to both sides of the equation,

2x - 2x + 42 = 3x - 42 - 2x + 42

42 = 3x - 2x - 42 + 42

42 = x

Therefore, the value of x is 42. Now, the measure of each angle can be written as,

(2x)° = 2(42) = 84°

(3x - 42)° = 3(42) - 42 = 84°

Hence, the value of x is 42 and the measure of the two given angles is 84° each.

Answer:360

Step-by-step explanation:g-g5

The rate of interest will be 0.35.

Compound interest is the interest calculated on the principal and the interest accumulated over the previous period.

[tex]CI = P(1+\frac{r}{n}) ^{nt} -P[/tex]

and, the Amount is given by

[tex]A = P(1+\frac{r}{n} )^{nt}[/tex]

Where,

A is amount

P is principal

r is rate of interest

n is number of times interest is compounded per year

t is time

According to the given question

Principal, P = $210

Amount, A = $250

Time, t = 5 years

n = 1

Therefore, the interest rate is given by

Amount = [tex]P(1+\frac{r}{n}) ^{nt}[/tex]

⇒[tex]250 = 210(1+\frac{r}{1}) ^{5}[/tex]

⇒[tex]\frac{250}{210} =(1+r)^{5}[/tex]

⇒[tex]1.19 = (1+r)^{5}[/tex]

⇒[tex]\sqrt[5]{1.19} = 1+r\\[/tex]

⇒ 1.035 = 1 + r

⇒ r = 1.035 - 1

⇒ r = 0.35

Hence, the interest rate is o.35.

Step-by-step explanation:

Answer:

a. x is equal to the number of sweat shirts made

b. $1100 is I think the base cost it takes to produce shirts

c. x=30

d. $5845

hope I helped.

Step-by-step explanation:

a. context

b. if x=the number of sweat shirts made then 65×x means that it costs $65 to produce one shirt and in that case to make any shirts it would cost $1100 to get the process set up so that they can make the shirts.

c. if c(x)=3050 then that means that that is the total cost to make all the shirts they made at that time. We know x is the number of shirts and because of that we want to solve for x. to do that we need to isolate x, the first step would be to take 3050 and sub that into the first equation

3050=1100+65x

subtract 1100 from both sides

3050-1100=65x

1950=65x

divide both sides by 65

1950÷65=x

simplify

30=x

d. you take the equation at the top c(x)=1100+65x and sub in 73 for x.

1100+(65×73)

simplify

1100+4745=5845

Answer:

8.66 m

Step-by-step explanation:

Given that,

The distance from the top of the building to the tip of the shadow is 14 m

The height of the building is 11 m.

We need to find the length of the shadow. we can see that the length of the shadow forms the base of the triangle.

The distance from the top of the building to the tip of the shadow form hypotensue and height of the building forms perpendicular. So, we can use Pythagoras theorem to find the base.

So,

[tex]H^2=b^2+h^2\\\\b^2=H^2-h^2\\\\b=\sqrt{14^{2}-11^{2}}\\\\b=8.66\ m[/tex]

So, the length of the shadow is 8.66 m.

Step-by-step explanation:

9 = x + y; x= 9-y

44 = 4x + 6y
