Answers

Answer:

Given data

We are told that the exchange rate is

£1=$1.55

if chris has £720

then £1 is the same as $1.55

£720 will be x

cross multiply

x= 720*1.55

x= $1116

find sin A and B, cos B and A, and tan B and A

Answers

Step-by-step explanation:

[tex] \sin(a) = \frac{7}{25} = 0.28 \\ \sin(b) = \frac{24}{25} = 0.96 \\ \cos(a) = \frac{24}{25} = 0.96 \\ \cos(b) = \frac{7}{25} = 0.28 [/tex]

tan(A)= 7/24= 0.29

tan(B)= 24/7=3.42

A=16.26°

What is the value for x and for y?

Answers

Answer:

20+7x=90

x=10

50+2y=90

y=20

I think
X=10
Y=20
Because a straight line is 180. So 180-20=160 from there you see that one of the angles is a right angle, you can tell this by that it has that little cube in the middle. So 160-90=70 that means that 7x=70 bit you are trying to find for x so divid 70 by 7 that equals 10.
Now to solve for why you have to plug in the information you already know. Vertical angles are congruent. That means that the that the 20 goes straight across and 7x with is actually 70 goes straight across. Now you already know the angle in the middle is 90 but this this it’s split. Since x is 10 multiply 5 by 10 then you get 50 now 90-50=40. 2y is 40 divide it by 2 to get y=20.
I’m bad at explaining so I hope I didn’t confuse you.

If using the method of completing the square to solve the quadratic equation x^2-5x-19=0x, which number would have to be added to "complete the square"?

Answers

Answer:

25/4 or 6.25

Step-by-step explanation:

Given that the general equation of a quadratic equation is given as

ax^2 + bx + c = 0, to complete the square, we subtract c from both sides of the equation and add the square of (b/2a) to both sides.

Hence given x^2-5x-19=0, to complete the square, we add

(-5/2)^2 to both sides following the illustration given.

This is 25/4 or 6.24

Area of the rectangle = L X W

Area of the rectangle = 4 X 2

Area of the rectangle = 8 inches

If the drawing is 1/5 of the actual air conditioning unit, then you multiply the reciprocal which is 5 times the area of the drawing. When you want to enlarge it has to be a whole number. When you want to reduce you multiply by a fraction.

So 8 inches X 5 = 40 inches is the actual area of the unit.

Carolyn borrowed $38,500 to pay
for college. If the interest rate is
3.2%, how much total will she
have paid after 10 years?

Answers

Answer:

$50820

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 3.2%/100 = 0.032 per year,

then, solving our equation

I = 38500 × 0.032 × 10 = 12320

I = $ 12,320.00

The simple interest accumulated

on a principal of $ 38,500.00

at a rate of 3.2% per year

for 10 years is $ 12,320.00.

The figure below shows a shaded rectangular region inside a large rectangle:

A rectangle of length 10 units and width 5 units is shown. Inside this rectangle is a smaller rectangle of length 4 units and width 3 units placed symmetrically inside the larger rectangle. The smaller rectangle is shaded gray.

What is the probability that a point chosen inside the large rectangle is not in the shaded region?

76%
50%
24%
12%

Answers

The area of the smaller rectangle is 12, and the area of the bigger one is 50, so the probability that it is not chosen inside the shaded region is (50-12)/(50)=76%
