Answer:
Rachel drove on Saturday = 503 miles
Rachel drove on Sunday = 438 miles
Step-by-step explanation:
As given , Rachel drove 65 miles less on Sunday than she did on Saturday.
Let us suppose
Rachel drove on Saturday = x
Rachel drove on Sunday = y
then, we get
y = x - 65
Also given, If twice the miles was driven on Sunday is 373 more than the number of miles driven on Saturday
then , we get
2y = 373 + x
⇒2(x - 65) = 373 + x
⇒2x - 130 = 373 + x
⇒2x - x = 373 + 130
⇒x = 503
∴ we get
Rachel drove on Saturday = x = 503
Rachel drove on Sunday = y = x - 65 = 503 - 65 = 438
A circular "No Parking" road sign has a diameter of 26 inches.
Which measurement is closest to the area of the sign in square inches?
81.64 in.²
163.28 in.²
530.66 in.²
2,122.64 in.²
Answer:
i think 81.64
Step-by-step explanation:
The area of the road sign in the circular shape of diameter 26 inches is closest to 530.66 in².
A road sign "No Parking" is given in a circular shape of diameter 26 inches. we need to find the area of the sign.
What is the area of a circle?The area of the circle is pie times the square of the radius of a given circle.
The area of the circle = [tex]\rm \pi r^{2}[/tex]
The diameter of the circle is 26 in so, the radius will be half of the diameter which will be 13 in.
Now, the area of the circle = [tex]\rm \pi r^{2}[/tex]
the area of the circle = 3.14 × 13 × 13
= 530.66 in²
Hence, the area of a circle of diameter 26 inches is equal to 530.66 in².

Toko sepatu memberi diskon 30% untuk semua barang.Jika tasya membeli sepasang sepatu dan ia membayar Rp 336.000,00 setelah mendapat diskon,harga sepasang sepatu tersebut sebelum diskon adalah
Answer:
IDR 480,000
Step-by-step explanation:
Persentase diskon = Harga lama - Harga baru / Harga lama
Harga lama = Harga sebelum diskon = x
Harga Baru = IDR 336000
Persentase diskon = 30%
Karenanya:
30% = x - 336000 / x
30/100 = x - 336000 / x
0.3 = x - 336000 / x
Cross Multiply
0.3 × x = x - 336000
0.3x = x - 336000
x - 0.3x = 336000
0.7x = 336000
x = 336000 / 0.7
x = IDR 480,000

a.k=2
b.k=3
c.k=4
d.k=5
Answer:
c. k=4
Step-by-step explanation:
5 in 4 places is 20 4 is a constant variation
The value of constant of variation k is 4.
Since, q varies directly as r.
[tex]q=kr[/tex]
Where k is constant of variation.
Substitute.[tex]q=20,r=5[/tex] in above equation
[tex]k=\frac{20}{5} =4[/tex]

If y - 18 = 14, then what is the value of 3(y + 5) ?
Answer: y = 980.333
Step-by-step explanation:
y-18=14
add 18 to each side
y = 32
Substitute 32 for y in 3(y+5)
3(32 + 5)
3(37)
111
So 3(y+5) = 111
Find the value of the variable y:
y-18=14 Add 18 on both sides:
y = 32
= 3y+15
_____________________
3y+15 = 2,956
3y+15 = 2956
3y = 2941
y = 980.333
