Answer:
(3 , 2.5)
Step-by-step explanation:
.5x + y = 4
y = .5x+1
.5x + (.5x + 1) = 4
x + 1 = 4
x = 3
y = .5(3)+1
y = 1.5 + 1
y = 2.5
Answer:
<em> 1005 girls</em>
Step-by-step explanation:
From the question we are given ratio of boys to girls as 7 : 29
Total ratio will be 7 + 29 = 36
Total students in the school = 1248 students
Number of girls in the school = 29/36 * 1248
Number of girls in the school = 29 * 35
Number of girls in the school = 1005
<em>Hence the approximate total number of girls in the school is 1005 girls</em>
<em></em>
<em>Note that the ratio was assumed since we are not given in question</em>
Volume is measured by squared units, which is why you could use cubes to represent the volume of a figure. Since volume means the entire figure, you have to stack the cubes one on top of the other and fill the entire cube in an orderly fashion to best identify the volume. Hope this help! :)
Answer:
Step-by-step explanation:
The top and bottom triangles have two congruent sides with different included angles.
- AB = AD and AC is common side.
<u>The greater angle has greater op</u>posite side.
- The ∠BAC is greater than the ∠DAC as opposite side of the first (22) is greater than the opposite side of the second (16).
The ∠DAC must be greater than zero but smaller than 48°.
<u>Required inequality is:
</u>
- 0 < 2x - 12 < 48
- 12 < 2x < 60
- 6 < x < 30
So x has a value between 6 and 30
