If angle pqt is (3x+47)and angle sqr is (6x-25), find the measure of angle sqr
Radda [10]

Answer:

Angle sqr = 119°

Step-by-step explanation:

In the above question, we are given:

angle pqt is (3x+47)°

angle sqr is (6x-25)°

Angle pqt = Angle sat

We solve for x

3x + 47 = 6x - 25

Collect like terms

47 + 25 = 6x - 3x

72 = 3x

x = 72/3

x = 24

We solve for the measure of angle sqr

Angle sqr = (6x - 25)

x = 24

6 × 24 - 25

144 - 25

= 119°

1. To determine simple interest, we use the formula i=prt where i is the interest, p is the principal or initial amount, r is th
Andrews [41]

Step-by-step explanation:

To determine simple interest, we use the formula

I=Prt

where I is the interest, p is the principal or initial amount, r is the interest rate is in the unit of years and t is the time in years

When the times is 3 years , then we plug in 3 for 't' directly

I=Pr(3)\\

we know that 1 year = 12 months

Suppose, the time is given in months then we divide time 't' by 12

When the times is 4 months , then we plug in 4 for 't' and divide by 12

I=\frac{Pr(4)}{12}

we know that 1 year = 365 days

Suppose, the time is given in days then we divide time 't' by 365

When the times is 45 days , then we plug in 45 for 't' and divide by 365

I=\frac{Pr(45)}{365}

Which equation shows y = -1/2x + 4 is in standard form?
Scrat [10]

For this case we have that by definition, the standard way to write the equation of a line, is given by:

ax + by = c

Where a, b and c are integers.

Given y =-\frac{1}{2}x+ 4

We can write it in the standard way:

\frac{1}{2}x+ y = 4

a=\frac{1}{2} and by the previous definition, the numbers a, b and c must be integers.

Thus, we multiply the equation by 2, on both sides so as not to alter the equality.

2*\frac{1}{2}x+ 2 * y= 2 * 4

x + 2y = 8

Thus, the equation of y =-\frac{1}{2}x+ 4 , in its standard form is given by:

x + 2y = 8

Answer:

Option B
