Pam and her brother both open savings accounts. each begin with a
balance of $0. For every $2 is that Pam saves in her account her brother
saves $5 in his account
P:bro=2:5
when P=40 what is bro?
2/5=40/b
times 5b both sides
2b=200
divide 2
b=100
bro has $100
not sure what tape diagram is
Answer:
D. y = - x
Step-by-step explanation:
y=mx+b
Slope = m= (-3-2)/(3+2)=-1
The line passes through (-2,2)
2=-(-2)+b
b=0

Step-by-step explanation:
Think that a triangle is equal to 180
Answer:
about 100 cm²
Step-by-step explanation:
The side length of the rhombus is 1/4 of the perimeter so is 10 cm. The length of half of the other diagonal will be the length of the leg of a right triangle with hypotenuse 10 and leg 7 (half the given diagonal).
d= √(10² -7²) = √51
Then the area of the rhombus is the product of this and the given diagonal:
A = (14 cm)(√51 cm) ≈ 99.98 cm²
The area of the rhombus is about 100 cm².
Answer:
volume = 456 in³
Step-by-step explanation:
volume = 2(3 x 8 x 6) + (4 x 7 x 6) = 288+ 168 = 456 in³
