Answer:

Assuming the question is asking for angle B, it measures 23°

Step-by-step explanation:

If angle A = 67°, and angle A and angle B are complementary, then you know they add up to 90°.

angle A + angle B = 90°

67° + Angle B = 90°

Angle B = 23°

Answer:

The probability is $G = 85%$

Step-by-step explanation:

From the question we are told that

The percentage of parents that have one child under 18 in their homes is k = 15%

The percentage of parents that have two children is T = 65%

The percentage of parents that have three or more children is Y = 20%

Generally the probability that any given family who is selected have two or more children at home is mathematically evaluated as

$G = T + Y$

=> $G = 65% + 20%$

=> $G = 85%$

A dog has three puppies. Spot weighs 12 ounces. Rascal weighs 9.5 ounces. Socks weighs 10.2 ounces. What is the total weight of

mario62 [17]

Answer:

c. 32 ounces

Step-by-step explanation:

Given that:

The weight of the Spot = 12 ounces

The weight of Rascal = 9.5 ounces; &

The weight of Socks = 10.2 ounces.

To find the litters' total weight, we will sum all the given number of the puppies.

i.e. Total weight of the litter = (12 + 9.5 + 10.2) ounces

Total weight of the litter = 31.7 ounces

Total weight of the litter $\simeq$ 32 ounces to the correct number of significant figures.

A number is 5 more than 3 times another number. The sum of the two numbers is 33. As an equation, this is written x + 3x + 5 = 3

Cloud [144]

Answer:

x=7, so the smaller number is 7 and the larger number is 21.

Step-by-step explanation:

x=3x+5=33

Let x=3:

(3)+3(3)+5=3+9+5=17, not 33, so x is not 3

Let x=5:

(5)+3(5)+5=5+15+5=25, not 33, so x is not 5

Let x=7:

(7)+3(7)+5=7+21+5=33, so x=7

Let x=9:

(9)+3(9)+5=9+27+5=41, not 33, so x is not 9

Therefore x=7. Because x represents the smaller number, and the larger number is 3 times the smaller number, the smaller number is 7 and the larger number is 3(7)=21.
