the students have 12 bags of balloon with 24 balloons in each bag they have filled 139 with air. if they use all the bags how many still need to be filled with air
A.67
B.149
C.288
D.365​

Answers

Answer:

149

Step-by-step explanation:

12× 24 = 288

228 - 139 = 149

Answer:

B. 149

Step-by-step explanation:

If the students have already filled 139 balloons with air and are going to use all the bags. They would need to fill 149 more balloons.

The first step would be to find the total number of ballons by calculating 12x24 which will give you 288.

From here you would need to subtract the number of ballons that are already filled with air from the balloons that remain which would be 288-139. This would give you a total of 149 balloons that still need to be inflated.

Determine the value of x, y, w and z.. Round to the nearest tenths place if necessary.
X =
y =
W =
Z=

Answers

Answer:

w=5   x=2.1    y=5.4   z= 14.1

Step-by-step explanation:

w² = 13² - 12² = 25

w = 5

cos ∠1 = 12/13 = 13/(12+x)

12 (12+x) = 13 x 13 = 169

144 + 12x = 169

12x = 25

x = 25/12 = 2.08 = 2.1

∠1 + ∠2 = 90°

∠2 + ∠4= 90°    ∠4 = ∠1

sin ∠4 = x/y = sin ∠1 = 5/13

5y = 13x

y = 13/5 x = 13/5 * 25/12 = 65/12 = 5.4

z = 12 + x = 12 + 2.08 = 14.08 = 14.1

Help me pls i dont understand this

Answers

Step-by-step explanation:

Notice that:

15x = 5 * 3x and 10y = 5 * 2y.

Since there is a common factor of 5,

we can take out the factor.

=> 15x + 10y = (5)(3x) + (5)(2y) = 5(3x + 2y).

Answer: 5/8 miles

Step-by-step explanation:

1. Add the distance from home to school, and from school to post office (7/8+5/6 = 41/24)

2. Figure out how many miles the trip was in total, given that she can travel a mile in 18 minutes and the trip was 42 minutes, by dividing 42/18, which equals [tex]2\frac{1}{3}[/tex]. The trip was [tex]2\frac{1}{3}[/tex] miles long.

3. Now, given that she has already traveled 41/24 miles from her home to the post office, subtract 41/24 from [tex]2\frac{1}{3}[/tex]. This equals 5/8, meaning that she traveled 5/8 miles from Post office to her friend's home.

Maybe it will me 5/8 tell me if its right

C. [tex]\frac{4}{5}[/tex]

Step-by-step explanation:

In order to find the slope knowing two points, use the slope formula [tex]\frac{y_2 - y_1}{x_2-x_1}[/tex]. [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of one point the line intersects, and [tex]x_2[/tex] and [tex]y_2[/tex] represent the x and y values of another point the line intersects.

Knowing this, use the points (-4, -4) and (6, 4) for the formula. Substitute -4 for [tex]x_1[/tex], -4 for [tex]y_1[/tex], 6 for [tex]x_2[/tex], and 4 for [tex]y_2[/tex]. Then, simplify:

[tex]\frac{(4) - (-4)}{(6) - (-4)} \\= \frac{4+4}{6+4} \\= \frac{8}{10} \\= \frac{4}{5}[/tex]

Thus, [tex]\frac{4}{5}[/tex] is the slope of the line.

Answer:

yes

Step-by-step explanation:

Frequent and detailed measurements help scientists make models of and determine changes in Earth's water cycle. The water cycle describes how water evaporates from the surface of the earth, rises into the atmosphere, cools and condenses into rain or snow in clouds, and falls again to the surface as precipitation.

Answer: angle R and T = 55; angle S and U = 125

Step-by-step explanation:

Answer:

∠S and ∠U = 125° and ∠R and ∠T = 55°

Step-by-step explanation:

The interior angles of a parallelogram with differing values form a supplementary angle meaning the sum is 180°. Use this information to make an equation.

11x + 4 + 5x = 180

16x + 4 = 180

16x = 176

x = 11

Substitute the solution for x to find the interior angles.

11(11) + 4 = 121 + 4 = 125

5(11) = 55
