Answer:
Step-by-step explanation:
100 - 3(3y - 4x) = 100 - 3(18 - 16) = 100 - 3(2) = 100 - 6 = 94

Step-by-step explanation:
Answer:
QR=8
QU=76
Measure of arc ST=114°
Measure of arc QR=114°
Measure of arc XT=57°
Step-by-step explanation:
Given that,
YU=YV
ST=16
mQS=34
mRT=98
We will use pythagoras theorem,
QR=8
QU=76
QR=ST
Since they span the same arc, let the arc be x.
360 - QS - RT = QR + ST
Recall that QR=ST
360 - 34 - 98 = x + x
228 = 2x
Divide both side by 2
X= 228/2
X=114°
Therefore, the measure of the arc ST and the arc QR=114°
Measure of span of arc XT will be:
= 1/2× (arc ST)
= 1/2 × 114
= 57°

I saw the image that should accompany the above problem.
Courtyard: Length=22 ft; Width = 12 ft
Fountain: Length = 6 ft; Width = ?
Area of the courtyard = 22 ft * 12 ft = 264 square feet
Part of the courtyard covered with stone has an area of 246 square feet.
Area of the fountain = 264 square feet - 246 feet = 18 square feet.
A) Width of the fountain.
Area of the fountain = Length * width
18 square feet = 6 ft * w
18 sq.ft / 6ft = w
3 ft = width
B.) Fraction of the area of the courtyard will be occupied by the fountain.
Area of the fountain: 18 square feet
Area of the courtyard: 264 square feet
18/264 = 3/44
18 ÷ 6 = 3
264 ÷ 6 = 44
