How many integers between $1$ and $200$ are multiples of both $3$ and $5$ but not of either $4$ or $7$

Rainbow [258]

There are only 13 multiples of both 3 and 5, since

$200 = 3\cdot5\cdot13 + 5$

From these integers, we eliminate any that are also divisible by 4 or 7.

$3\cdot5\cdot4 = 60 \implies \{60,120,180\}$

$3\cdot5\cdot7 = 105 \implies \{105\}$

so there are 13 - 4 = 9 such integers.

What is the value of x?

In-s [12.5K]

Answer:

Step-by-step explanation:

The vertically opposite angles make it possible to say that the two triangles are similar. The reason is that you are give 1 pair of angles being equal and the vertically opposite angles make a second pair. By AA, the triangles are similar.

Hint: always put the line labeled x in the numerator of the proportion that you set up.

x/8 = 15/5 For just this question reduce the right side

x/8 = 3 Now multiply both sides by 8

8*x/8 = 3*8 Do the multiplicaton

x = 24

What is the simplified expression for 7 power 4 multiplied by 7 power 6 over 7 power 8?

Masteriza [31]

Answer:

The simplified expression of $\frac{7^{4}.7^{6}}{7^{8}}$ is 7² ⇒ C

Step-by-step explanation:

Let us revise some rules of exponent

$a^{m}$ × $a^{n}$ = $a^{m+n}$

$\frac{a^{m}}{a^{n}}$ = $a^{m-n}$

Let us solve the question

∵ The expression is $\frac{7^{4}.7^{6}}{7^{8}}$

→ By using the first rule above add the exponents of 7

∴ $\frac{7^{4}.7^{6}}{7^{8}}$ = $\frac{7^{4+6}}{7^{8}}$

∴ $\frac{7^{4}.7^{6}}{7^{8}}$ = $\frac{7^{10}}{7^{8}}$

→ By using the second rule above, subtract the exponents of 7

∵ $\frac{7^{4}.7^{6}}{7^{8}}$ = $7^{10-8}$

∴ $\frac{7^{4}.7^{6}}{7^{8}}$ = 7²

∴ The simplified expression of $\frac{7^{4}.7^{6}}{7^{8}}$ is 7²
